Developments in computer aided diagnosis used for
Tuberculosis detection
using chest radiography: A survey |
Author (s): |
K. G. Satheeshkumar and Alex Noel Joseph Raj |
Abstract: |
One of the major health problems of global concern is Tuberculosis (TB).
According to the global report of WHO, approximately 1.3 million people
died out of 8.6 million reported with TB in 2012. Most of the TB death
can be prevented if it is detected at an early stage. Hindrance to that
is improper diagnosis at the initial stage. Chest X ray (CXR) image is
the primary medical diagnosis used for identifying the lung diseases at
the first stage. Interpreting the information from CXR depends upon the
experience of the doctor and the possibility of over and under diagnosis
is very high. To identify the disease accurately a proper classification
tool along with computer aided diagnosis should be used. Neural network
can be used as a classifier tool for the same. Advancement in VLSI
technology reduces the computational complexity of Artificial Neural
Network (ANN). The research of neural networks in medical images (x-ray
images of TB, lung cancer) diagnosis during adolescent stage, show a lot
of remarkable improvements. This paper describes the fundamentals of
radiology of lungs (analysis of CXR), image processing, ANN and recent
developments in this area using computer aided diagnosis (CAD). We have
gone through the Chest Radiology and found that an accurate classifier
is required for proper diagnosis. |

methodology |
Author (s): |
S. Dhamodaran, E. Archana and J. S. Umashankar |
Abstract: |
Extensible Access Control Mark-Up Language (XACML) based solutions for
dynamic privacy policy management and decision enforcement is proposed
in recent research to enhance the accuracy of the component like Policy
Enforcement Point (PEP) and Policy Decision Point (PDP). Composition
plan will be generated where any service WS1 which depends on another
service WS2. To manage data privacy, Web Services defines a privacy
policy for each instance in its OWL repository. Each repository manages
data access through SPARQL endpoint. A dynamic, semantic-based privacy
policy management framework is proposed in our system on the top of the
XACML reference architecture for policy-based access control. XACML is a
protocol of communication between a PDP and PEP used for context
handling. The context handler accepts the request from an XACML formed
by PEP and sends it to the PDP. The PDP uses the attributes to evaluate
policies and it returns the final decision. |

Performance evaluation of UDP based on traffic size and traffic load
using NS2 |
Author (s): |
Saif Uldun and Raed Alsaqour |
Abstract: |
This study concerned on examining network matrices over user datagram
protocol (UDP). The current challenges associated with network
performance and streaming of packets was the main motivation for the
researchers. A review of UDP was given with the relation to its network
performance. We found UDP offer a minimal, unreliable, best-effort and
message-passing transport to applications. Hence, a further examination
of its performance was performed using NS2 on aspects related to traffic
size and traffic load. The simulation result revealed that when
establishing communication over UDP, it was noticed that changing packet
size and traffic load has a small effect on UDP performance in which it
was found a minimal associated end system state. |

Author (s): |
Ammadi Abdelaziz and Elbelkacimi Mourad |
Abstract: |
In this work provides for the publication of an optimal technique to end
the problem of lack of chlorine in drinking water ends of the
distribution network and ensure sufficient concentrations by chlorine
injections through intermediaries chlorination stations to maintain the
quality of drinking water to the consumer. This technique has two main
objectives namely to minimize the number of chlorine deficit nodes and
the number of stations to be set. This method is divided into two parts:- the first can detect target areas (chlorine <standard), these areas
will be classified in order of importance (number of nodes lover, number
of nodes swallows, flow ...)- Reduce the number of these nodes deficit up by chlorine injection. To meet these two criteria, we have developed an optimization tool able
to offer sound solutions to minimize both the number of loss and nodes
and the number of stations to be set. |

Effective clusters culled out through algorithmic implementations |
Author (s): |
Manalina and K. Mohana Prasad |
Abstract: |
Data mining is a technology that collects and search a bulk of data from
database to discover relationship among data. It is an application that
view data from different angles and group it into information that is
useful in many perspectives. There are different types of clustering
methods that used to grouping the generated data sets such as K-means etc.
K-means algorithm is a centroid based technique and has input parameter
as k. This technique has two restrictions such as k-means value
selection and centroid selection i.e. the size of cluster is assigned by
manually and the centroid value is selected by randomly. These two
parameter impacts on the clustering performance massively. Another
metric such as distance metric also have impact on choosing the cluster
also presented. This paper presents powerful K-means (PKM). To show the
performance of the proposed algorithm various set of dataset have been
taken. That has been applied on traditional K-means and proposed
algorithm. The experimental result shows proposed algorithm gives better
result when compared to traditional k-means. |

An improved load-displacement prediction for a coned disc spring using
the energy method |
Author (s): |
Noor Fawazi and Jung-Youn Lee |
Abstract: |
An improved computation of the load-displacement prediction for a coned
disc spring is proposed. This work is an extension work of the previous
proposed energy-based computation for coned disc springs. To show the
validity of the improved method, the load-displacement results using the
improved computation, the previous proposed method, and the finite
element analyses are compared. In this work, the improved computation
and the finite element analyses have accounted for the radial deflection
of the disc spring in the form of energy method. This is different in
the previous work where the radial deflection of the disc spring was
ignored and the comparison to the finite element analyses without
accounting the radial deflection is not practical. The present work
makes the comparison to the finite element analyses to be more
reasonable and more practical. |

Author (s): |
Abdallah S. Abdelrahman, Rashid A. Saeed and Raed A. Alsaqour |
Abstract: |
In recent years, Voice over IP (VoIP) has gained a lot of popularity and
become an industry favorite over Public Switching Telephone Networks (PSTN)
with regards to voice communication. This paper work consists of
creating a VoIP network and testing for its known faults. Through this
paper, we get a better understanding of the underlying layers of the
network and see if and where improvements can be made. In implementation
stage the Real-time Transport Protocol (RTP) packets for VoIP
applications had been sent and compared with TCP/UDP packets to obtain
results which are mainly related to Quality of Service (QoS) factors.
The attained result approved that RTP consider to be better to reduce a
packet loss than UDP and also approved that UDP/RTP are most reliable
because they had a very small delay and jitter in contrast with TCP.
Hence, we find that, UDP/RTP are more balance and prefer than TCP in
real-time applications such as VoIP. |

Author (s): |
S. Vimala and S. K. Srivatsa |
Abstract: |
In this paper, the necessity to achieve a capable Medium Access Control
protocol subject to bandwidth constraints is considered. As Medium
Access Control has an important role on the bandwidth allotment,
bandwidth efficiency is one of the main concept in the design of Medium
Access Control (MAC) protocols for MANETs. Nodes are placed in an ad hoc
manner, when transmitting the packets nodes will be inactive for more
time and when it becomes an active state, some characteristics of MANETs
and applications motivate a MAC that is different from IEEE 802.11 in
some ways like Live Bandwidth Allotment and self-organization are the
targets. The significance of routing protocol that makes security as
wanted by providing a broad architecture of Secured PPEM Mechanism based
Multi-Hop Strong Path Geographic Routing protocol (SMHSP) with effective
key management, secure neighbor detection, secure routing data’s,
finding malicious nodes, and eliminating these nodes from routing table
is considered. In this paper, we would implement the LBA-MAC protocol
under SMHSP routing protocol and compare the performance parameters by
varying number of nodes in the MANETs. |

An effective retrieval of secured and ranked data in cloud environment |
Author (s): |
R. Shanmugaapriyaa and A. Safiya Parvin |
Abstract: |
Cloud computing is a successful environment due to many recent
technologies. The main advantage of using cloud computing is that it
allows users to store a copious amount of data. The mobile data which
has been redistributed to the third party cloud requires protection from
the trapdoor, intruders to do so the data were encrypted using
asymmetric encryption into blocks and then distributed to the various
cloud storages. But there exists some difficulties in search of those
data in cloud, which may not give an accurate search results. The main
aim of this paper is to overcome this drawback through gateway
encryption and blind storage, through dynamic block splitting in order
to preserve the redistributed data in the cloud storage. Natural
Language Processing technique is used to extract keywords by secured
multi-keyword search over the cloud data which pre computes the
resulting data that the user needs to search and gives accurate and
relevant results by without downloading the files contents .Indexing and
the privilege preferences were also done prior to enhance the security
and decryption of the entire group members file content is also done. |

On the performance of segment averaging of
Discrete Cosine Transform
coefficients on musical instruments tone recognition |
Author (s): |
Linggo Sumarno |
Abstract: |
In the Discrete Cosine Transform (DCT) domain, the tones of musical
instruments can be divided into two groups. The first one with the
single significant local peaks and the second one with the multiple
significant local peaks. The second one can be divided into two sub
groups, which have many and a few significant local peaks. This research
deal with multiple significant local peaks. In this research, segment
averaging was used to reduce the number of DCT coefficients, in the DCT
domain. In this case, the reduced number of DCT coefficients called
feature extraction coefficients. Based on the experiment, when the
segment averaging of DCT coefficients was used optimally for the tones
which had many (i.e. thirteen) and a few (i.e. three) significant local
peaks, it could give 8 and 16 feature extraction coefficients
respectively. So, in order that segment averaging of DCT coefficients
could be used optimally, either for the tones which have many or a few
significant local peaks in the DCT domain, it could use segment length 4
points and DCT length 64 points. By using it, it could give 16 feature
extraction coefficients. |

Author (s): |
Luca Piancastelli, Leonardo Frizziero, Simone Pica and Giampiero Donnici |
Abstract: |
In high altitude operations, the cooling system takes part to the
vehicle design optimization process. An integrated design of the cooling
ducts is strictly necessary. At high altitudes, the cooling air is taken
from high-pressure areas into an alternate, extremely optimized, path. A
diffuser reduces the airspeed and increases pressure of the cooling air.
Then a group of high performance finned radiators rejects the heat from
coolant, air charge and oil. The high altitude, after diffuser radiator
performance is discussed in this paper. At first high performance
Formula 1 radiators are introduced and discussed. Experimental data are
also exposed and summarized. The pressure drop and heat rejection are
expressed in function or Re and Pr numbers of cooling air. Then the
radiator performance at high altitude is extrapolated from the ground
test data. Finally a few suggestions on radiator and cooling ducts
arrangement are introduced. |

Mustapha |
Abstract: |
This paper proposes a novel constraint handling strategy that is based
on random walk (RW) for metaheuristic techniques in solving economic
dispatch (ED) problems. To implement this CHM, a Cuckoo Search (CS)
algorithm has been adopted. The absolute as well as the relative
performance of the resultant hybrid algorithm is experimentally
investigated using a standard test case with valve point effects.
Statistical parameters are used in order to evaluate the robustness of
the method. The proposed methodology proves that it outperforms
established methods such as particle swarm optimization and genetic
algorithm methods in terms of robustness and achieving consistent
results throughout all the trials in each experiment. |

N. F. Baharin, N. Sidek, S. M. A. Musa, A. I. Azmi, A. S. Abdullah, M.
Y. M. Noor and M. E. M. Roslan |
Abstract: |
A refractive index sensor based modal interference in hollow core
photonic crystal fiber (HCPCF) is proposed and demonstrated. The sensor
is realized by splicing both ends of a HCPCF section to single mode
fiber (SMF). At both splicing points, the HCPCF air holes are fully
collapsed by the arc discharge. The collapsed regions excite and
recombine core and cladding modes which formed modal interference for
sensing purpose. The HCPCF sensor is tested in sugar solution and the
response is measured from the wavelength shift in the interference
spectra. The achieved sensitivity and resolution are 36.184 nm/RIU and
5.53×10-4 RIU, respectively, in refractive index range between 1.3330
and 1.3775. Result also shows that the sensor has a small temperature
sensitivity of 19 pm/°C in the range of 35.5°C to 60.5 °C. The proposed
sensor potentially can be applied in biomedical, biological and chemical
applications. |

Abstract: |
A kinetic study of three Egyptian agricultural wastes has been conducted
at a heating rate of 5oC/min using thermo gravimetric analysis TGA. The
kinetic parameters (order of reaction, activation energy, and frequency
factor) have been determined from the TGA experiment measurements. The
kinetic results indicate that the thermal degradation is a first order
reaction. The activation energies (25.7 - 26.2 - 26.1) kJ/mol and the
pre-exponential factors (5.86E-3, 6.95E-3, and 6.95E-3) were attained
for cotton stalks, corn stalks, and rice straw, respectively. These
activation energy values are considered low, which specify the ease of
gasification of these three types of the agricultural wastes. |

transducer there were travel speed of the machine to the bottom hole and
the travel rate were registered. The paper has proved that existing
means of the objective control procedure of working conditions of the
URAL-20R machines do not provide best performance operation of the
winning machines. The motor loading indicators that the newest models of
the "URAL" machines have are adjusted to peak current and start alarming
about the overload at 60-70 % of the load to the driving motors. On the
basis of data analysis the paper has proved efficient operating
conditions of the URAL-20R combine operation. It is proved that during
the combine operation with its nominal performance of 7 t/min. as
compared to usual performance of 4 t/min., energy intensity on the
potash ore output recedes by 1, 5 times, and the extraction of the crude
ore (-0,25 mm) decreases by 30%. The paper has recommended the
stationary complex development registering load intensity and load

Author (s): |
M. K. Aravindan and K. Balamurugan |
Abstract: |
The current paper investigates the wear behaviour of sic and nano sic
reinforced with aluminium metal matrix composites were prepared by stir
casting method. In this method five sets of both the Almmcs were
produced with incorporating 2,4,6,8 and 10 wt% of sic and nano sic
particulate Aluminium composites, due to increase in weight percentage
of sic and nano sic particulates reduces the fracture toughness, which
results in higher wear rate. Plots depict that increase in %
reinforcement of sic and nano sic reduces wear up to around 5 to 7% and
beyond this the wear has a tendency to increase for Al composites. Pin
on disc wear tests were conducted and the results were gives the effect
of increasing sic with Aluminium increases wear rate. This work focuses
on developing an Aluminium metal matrix composite (AMMC) material for
turbocharger components made by wrought aluminium alloy with various
weight fractions of aluminium silicon carbide and nano silicon carbide
composites in order to make five different forms of metal matrix
composites comparison on wear behaviour were discussed. |

Robust fuzzy logic technique for low contrast image shadow removal |
Author (s): |
A. Sunandini and D. Usha Nandini |
Abstract: |
The shadows are playing very hazardous for recognizing objects in low
contrast Images. Shadow leads to the problem of false positive errors
and false negative errors. Shadows are created because the light source
has been blocked by object. In the existing method, suspected shadows
are extracted and removed by taking the shadow features into
consideration during image segmentation and by calculating the
statistical features of the image. But the main limitation of existing
method is that the dark objects which could be mistaken for shadows are
ruled out according to object properties and spatial relationship
between objects. Many effective algorithms have been proposed for shadow
detection but no algorithm is produced accurate results. In this project
robust fuzzy logic technique is using to eliminate shadow of object.
This method accurately identifies shadow areas with information such as
gray scale and brightness of the images. The threshold value is obtained
by s-curve from the estimated grayscale value of the shadow areas by
estimating control parameters. This method work perfectly for low
contrast, noisy and overlapped images. |

An efficient pilot carrier channel estimation using
Genetic Algorithm in MIMO-OFDM system |
Author (s): |
R. S. Ganesh and J. Jayakumari |
Abstract: |
MIMO-OFDM (multiple input multiple output-orthogonal frequency division
multiplexing) is an excellent technique used in modern wireless
communication systems. It has excellent quality of high speed data/voice
transmission with high spectral efficiency. The Least Square (LS) and
Minimum Mean Square Error (MMSE) channel estimation are the most common
methods presented by several researchers. Discrete Fourier Transform (DFT)-based
channel estimation is introduced to minimize the receiver noise
interference which cannot be possible in the LS and MMSE techniques.
Also, Genetic Algorithm-based optimized channel estimation is proposed
in this paper to identify the best channel matrix from the existing LS,
MMSE and DFT estimation algorithms. The simulation results clearly show
that the performance of optimized GA-based DFT channel estimation is
better than the LS and MMSE estimation. |

Comparative study of Image Fusion techniques in spatial and transform
domain |
Author (s): |
Bhuvaneswari Balachander and D. Dhanasekaran |
Abstract: |
The process by which different images or information from multiple
images are combined is termed as Image fusion which is achieved by
applying a sequence of operators on the images. Recently, a number of
image fusion techniques have been developed. This paper presents a
review on the main categories of image fusion namely spatial domain
technique, transform domain technique and statistical domain fusion
technique. Image Fusion is one of the latest fields adopted to solve the
problems of digital image; image fusion produces high-quality images
which contains additional information for the purposes of
interpretation, classification, segmentation and compression, etc. The
principle requirement of the fusion process is to identify the most
significant features in the input images and to transfer them without
loss of detail into the fused image. Image Fusion finds its application
in vast range of areas. It is used for medical diagnostics and
treatment. This paper presents a brief description of some of the
extensively used image fusion techniques. Comparison of all available
image fusion techniques concludes a better approach for future research
on image fusion. |

Short-term and long-term land subsidence calculation using analytical
relations and numerical modeling by FLAC3D software for southern part of
line three of Tehran subway under rail lines and investigation of influencing parameters |
Author (s): |
Hossein Soltani-Jigheh, Parviz Enany, Manouchehr Tajrostami and Ahmad
Yaghoubi |
Abstract: |
Earth response to digging an underground tunnel appears as changing
stress field and displacements around digging location and this point
depends on various factors such as geological conditions, geotechnical
characteristics, the drilling process and the implementation of final
and temporary maintenance. There should be a separation between these
items; 1) subsidence due to digging methods in tunneling 2) conditions on
the ground in terms of construction 3) loads available for subsidence in
cutting face and subsidence that occurs on the backside of cutting face.
However, due to the progress on the construction of automated machines,
such as the TBM and Road header, paying attention to benefits of each of
these devices is important to reduce occurrence of subsidence. Among all
a device like TBM can change stress and displacement in the lands around
the tunnel via simultaneously putting pressure on cutting face and walls
of tunnels using filler injection, and this change should be so that
amount of subsidence reach the minimum in short-term and long-term
period comparing to the traditional methods of digging underground
tunnels. In this research, calculation of land subsidence amount due to
a tunnel passing under rail lines and also investigation of influencing
parameters on subsidence using theoretical relations and modeling with
FLAC3D are done. In order to have a real sample, one of the lifelines in
Tehran subway was selected and influencing parameters including amount
and place of dynamic forces caused by passing trains from the ground,
underground tunnel boring method, and in the case of drilling with TBM,
pressure changes on cutting face and tunnel walls simultaneous with
digging the tunnel were considered. According to local observations and
carried out analyzes, subsidence of land in short-term using mapping
camera readings in long-term using analytical relations and computer
modeling is determined, so in the case of subsidence being situated in
dangerous range, injuries and irreparable damage be avoided through
providing suitable solutions. |

Author (s): |
Rudi Sugiono Suyono, Ofyar Z. Tamin, Sony S. Wibowo and Heru Purboyo H. P. |
Abstract: |
The concept of sustainability emerged in the early 1970s since The UN
Conference in Stockholm in 1972. The sustainability concept must be
implemented earlier in the strategic planning process, that the
appraisal plays a key role. Through the good appraisal process, all the
possibilities related to the impact of the implementation can be
identified earlier. The infrastructure development in the developing
countries, has the typical problems such as environmental, social and
economic, the large demand of infrastructure development, but has
inadequate funding and the issue of the short term and long term impact
that arising from infrastructure development which often cannot be
anticipated earlier. An appropriate working title for this new
assessment approach seems to be Strategic Sustainability Appraisal (SSA).
The emphasis of SSA is on comprehensive transport policies, assessing
policies simultaneously in order to detect possible interdependencies
and cumulative impacts, handling the three basic aspects of
sustainability equally. |

Abstract: |
The
effect of modified and non-modified starch as a filler was investigated
in this study. The blend of Polyvinyl Alcohol (PVA) and starch was
prepared as a film for further analysis. The starch was modified by an
acetylating process in which -OH group was substituted in the starch
solution. Fourier-transform infrared (FTIR) analysis was used to analyze
the presence of functional group of starch acetate. The biodegradable
plastic film composed of plantain peel starch and PVA blend was made
through solution casting method. The degradable film was produced by
compounding the starch with PVA and the use of glycerol as a
plasticizer. The blend was spread on the flat glass plate in order to
produce the film with even thickness. The casted film is dried in an
oven at 90oC for about one hour. The elasticity and strength of the film
then was analyzed through tensile test. It was found that the film
produced from modified starch has more flexibility and reliability
compared to non-modified starch. The highest tensile strength and
elongation at break of the film produced was found at 15g of the starch-PVA
blend. Meanwhile, the Young’s modulus obtained is concurrent to the
tensile strength of produced film. |

Detecting the smoothness of numerical solutions to the

of gas dynamics |
Author (s): |
Sudi Mungkasi, F. A. R. Sambada and I. Gusti Ketut Puja |
Abstract: |
Analytical solutions to the Euler equations for gas dynamics are not
available for general cases. The Euler equations are three simultaneous
partial differential equations representing the conservation of mass,
momentum, and energy of the gas. In this paper, the Euler equations are
solved using a finite volume numerical method. As the partial
differential equations are of hyperbolic type, their solutions admit
discontinuity. The finite volume solution is generally accurate at
smooth regions and inaccurate at rough regions. Knowing which regions of
the solutions where they are smooth or rough is the goal of this paper.
To achieve our goal, here we propose the weak local residual of the
entropy equation as a smoothness indicator for numerical solutions to
the Euler equations. |

Abstract: |
Lung cancer in human body is proving to be a catastrophic threat to the
mankind or humanity and is prime cause of deaths among other cancer
related fatalities. The presence of solitary/isolated pulmonary nodules
in human lungs in the form of benign or malignant calculates the gravity
of lung ailment or disorder. In our project we are using a literature
method for lung nodule detection, segmentation and
classification/taxonomy using computed tomography (CT) images. One of
the most common noise in CT imaging is an impulse noise which is caused
by unstable voltage. In this paper, a new decision based technique
called new adaptive median filter is presented which shows better
performance than those already being used. The CT slices are initially
preprocessed to remove the Gaussian noise by using Gaussian filter. Otsu
thresholding is applied to extract the region of Interest (ROI). We have
the different classifications about the nodules in the lung. It contains
the different method of classification, segmentation and detection
techniques. Malignant (virulent) cell presented in the lungs specified
nodules are classified for the therapy processes. Now, we will classify
the images into nodules and non-nodules. We will now take out the
object’s feature vectors in choosen /selected boxes. Lastly, the support
vector machine (SVM) is applied which will classify the extracted
feature vectors. The SVM will classify the images into normal or
abnormal based on the second order gray level co-occurance matrix
features. |

Author (s): |
Archana Shree S. and Vigneshwari S. |
Abstract: |
In recent days, web searching and security of the archives plays most
incredible progress. The enduring research prototypes many web search
show the result by searching the relevant data alone. Due to the mere
relevancy search, the users may loss some useful data which are not
included in the search result. Moreover, it also may consume more time
by searching the data sequentially. To overcome these challenges
stemming process is united with the existing model for searching the
both labelled and unlabelled documents. Furthermore, User Based
Advertisement (UBA) is included with the proposed search engine to
display the advertisements based on search. To improve the ranking
system, Time Stamp Based Analysis (TSBA) is incorporated in the process
for easy search of users. With these improvements downloading one's file
that are uploaded in the web search become quite easy. But security is a
major concern sending a request for downloading a data. In order to
overcome this difficulty, Email OTP Alert (EOTPA) is provided in the
proposed model to increase the security in web search. |

Author (s): |
Nidhin Raj A. and Sellamuthu R. |
Abstract: |
An
investigation was carried out to determine the effect of Ni addition on
the microstructure, hardness, tensile properties and wear rate of the
cast Al-0.4Mg-8Si alloy. The Al-0.4Mg-8Si alloy was melted in an
electric furnace and Ni was added to the melt in the appropriate amount.
The melt was cast in a metal mould. The cast specimens were solutionised
and aged. The microstructure was observed using an optical microscope
and the phases present in the microstructure were identified using
energy dispersive spectroscopy (EDS). The hardness, tensile properties,
wear rate and coefficient of friction (CoF) were determined. The
eutectic Si morphology was refined and an intermediate phase Al3Ni was
observed. The hardness and tensile properties increased, wear rate
decreased and CoF remained constant for the Ni modified alloy compared
to the base Al-0.4Mg-8Si alloy. It is concluded that the Ni addition
significantly improves the properties of the base alloy. |

T. Ch. Madhavi and S. Annamalai |
Abstract: |
Electrical conductivity of concrete is of current interest since it can
be used as a parameter relating to certain characteristics of concrete.
Electrical resistivity is the inverse of electrical conductivity. This
literary study indicates that moist concrete behave as a semiconductor
with resistivity of the order of 105 ohm-mm while oven-dried concrete
behaves as an insulator with resistivity of the order of 1012ohm-mm.The
methods of measuring resistivity are studied which draws to the fact
that Wenner probe method being the more reliable method. The principle
behind the measuring techniques is to quantify the conductive properties
of the microstructure or pore network of concrete. This study also

Author (s): |
J. Dinesh, G. Mohammad Ashraf and N. Radhika |
Abstract: |
The Al LM25/TiB2 (10 wt %) composite is fabricated using in-situ process
by stir casting method. LM25 alloy is melted in a graphite crucible at
8000C using electric furnace in argon gas atmosphere and a mixture of
K2TiF6 and KBF4 is added to the melt gradually through the hopper
attached at the top of the furnace. The melt is stirred with the aid of
mechanical stirrer which rotates at 200 rpm for 40 minutes
intermittently. The reaction between K2TiF6 and KBF4 in those conditions
results in the formation of TiB2. This melt is poured in the stainless
steel mould which is preheated at 2000C and the obtained casting have
dimension 100 mm length and 20 mm diameter. The composite specimens are
then machined according to the specification requirement of the
experiments. All the specimens are polished using emery sheets of grade
1/0 and 2/0 followed by velvet polisher. The specimen used for
microstructure analysis is further etched with Keller’s reagent.
Spectroscopy of LM25 alloy is carried out to observe its elemental
composition. X-ray diffraction is used to ensure the formation of TiB2
during casting process. Inverted metallurgical microscope and Vickers
hardness tester are used to study the microstructure and micro hardness
of the fabricated composite respectively. The X-ray diffraction results
revealed the formation of TiB2 particles in the fabricated composite.
Microstructure analysis revealed uniform distribution of TiB2 in the
aluminum matrix and Micro hardness test shows an increase in hardness of
the composite (91HV) as compared to the un reinforced alloy (82HV) by
10%. |

Pervious concrete or enhanced porosity concrete has a strictly gap
graded coarse aggregate phase and little or no fine aggregates so as to
facilitate the formation of an interconnected network of pores in the
material. The material is designed with cementitious material content
just enough to coat the coarse aggregate particles so that a
configuration that allows the passage of water at a much higher rate
than conventional concrete. The pervious concrete has main advantages
that improves city environment, recharge the ground by rain water and
could be used as pavement for light vehicles, pedestrian pathways,
parking lots, also it reduces the tire pavement interaction noise etc,
the effectiveness of a pervious concrete pavement depends as the
intrinsic permeability of the mass, and normally this is defined by the
porosity. This paper presents a new method for determining the
permeability or pervious concrete and provides design methodology to
prepare pervious concrete based on experimental test values of pervious

A novel approach to multi-objective OPF
by a new parallel non-dominated Sorting Genetic Algorithm-considering diverse constraints |
Author (s): |
S. Ragavan Swaminathan and E. Nandakumar |
Abstract: |
Transient stability constrained optimal power flow (TSCOPF) is able to
reduce costs while keeping the operation point away from the stability
boundary. While especially useful in modern power system operations,
TSCOPF problems are practically very hard to solve; unacceptable
computational time is considered to be one of the largest barriers in
applying TSCOPF-based solutions. The basic idea of the proposed method
is to model transient stability as an objective function rather than an
inequality constraint and consider classic Transient Stability
Constrained OPF (TSCOPF) as a tradeoff procedure using Pareto ideology.
Second, a parallel elitist Non-dominated Sorting Genetic Algorithm II (NSGA-II)
is used to solve the proposed multi-objective optimization problem; the
parallel algorithm shows an excellent acceleration effect and provides a
set of Pareto optimal solutions for decision makers to select. Case
study results demonstrate the proposed multi-objective algorithm in
IEEE39 bus system is quite strategic. |

A novel neural network approach to data classification |
Author (s): |
K. G. Nandha Kumar and T. Christopher |
Abstract: |
Data classification is a major task in data mining paradigm. In this
paper an artificial neural network approach is proposed for data
classification. In this approach data classification is accomplished
through a cluster analysis. It is a two-pass process, clusters are
created in the first step and classification is achieved from the
results of first pass. A self organizing map neural network (SOMNN) is
used for clustering in the first pass. In the second pass classification
task is completed by using multilayer neural networks (MNN). Basically
SOM is an unsupervised neural network and multilayer networks are
supervised neural network, hence this approach is a hybrid method. Nine
hybrid neural networks (HNN1 to HNN9) are constructed from the
combination of above said methods and are experimented. Performance of
each hybrid neural network is evaluated by using metrics such as
accuracy, precision, recall, and F-measure. Feed back of library users
is used as data set for classification. |

Berkeley synchronized algorithm based fault tolerant mechanism for
Computational Data Grid in cloud environment |
Author (s): |
Ramachandra V. Pujeri, S. N. Sivanandam and N. Suba Rani |
Abstract: |
Computational Data Grid provides massive resource sharing and aggregated
computing resources in a dynamic manner. Due to the limitation of
available heterogeneous resources distributed through several networks
in computational data grid, occurrence of failure poses severe problem.
Providing efficient fault tolerance mechanism is a key optimization
technique for improving scalability and attain QoS based fault tolerant
dynamic replication in a wise manner. In this paper, Merkle Damgard
Clock Synchronized based Fault Tolerant (MDCS-FT) mechanism is developed
to overcome the fault occurrence in computational data grid. MDCS-FT in
cloud services allows for concurrent transaction without relying on a
centralized grid component, which amounts for better scalability. Clock
Synchronized with Berkeley algorithm uses the optimized different data
grid sequences to attain QoS based fault tolerant dynamic replication.
Berkeley algorithm in MDCS-FT mechanism is more suitable for easily
identifying the fault with time server. Time server in MDCS-FT Mechanism
periodically fetches the time from all the clients and averages the
results on cloud zone to secure data objects replication in cloud data
grid by removing the fault. Experimental results demonstrate that the
proposed mechanism achieves better performance by improving the
scalability and QoS (error rate and transmission delay) and minimizes
the fault tolerance compared to the state-of-the-art works. |

Abstract: |
This paper reveals the fabrication of aluminium silicon carbide metal
matrix composite using stir casting method and various tests carried out
and their outcomes. Generally metal matrix composites are formed with
two constituents, one being a metal and the other material either being
a different metal or other material like ceramic or organic compound.
Metal matrix composites (MMC’s) are generally costly but their
performances justify the added cost. However various limitations exist
during formation of the composite and is counteracted by considering the
factors such as reactivity at the interface, volume fraction of the
reinforcing material and type of reinforcing material being added.
Aluminium silicon carbide metal matrix composite is prepared with Al
6082 as base material and SiC as reinforcement material. The weight of
the reinforcement material is varied from 0 to 10% and different test
samples are prepared. Various tests are conducted to evaluate the
performance of the composite and the results obtained are discussed. |

The mechanical behavior of Nano sized Al2o3 -reinforced
Al-Si7-Mg alloy
fabricated by powder metallurgy and forging |
Author (s): |
Sathiaraj G., Mani R., Muthuraj M. and Mayakannan S. |
Abstract: |
The study is to be undertaken to investigate the effect of Alumina
particle size, sintering temperature, sintering time on the
microstructure and mechanical properties of Al-Si7-Mg0.3 (A356). This
metal matrix composite has been investigate by powder metallurgy. Powder
metallurgy (PM) is a widely used fabrication method for producing metal
matrix composites. This usually involves three major stages: blending of
the metal and ceramic powders, pressing or cold compaction, and
sintering. These last two steps are often combined during hot pressing.
One of the advantages of PM compared to casting is having better control
on the microstructure, where better distribution of the reinforcement is
possible in PM compacts. Particle size and the amount of reinforcement
had pronounced effect on the mechanical properties of composites. Proper
addition of reinforcements to aluminum composites have a positive effect
on mechanical properties, such as hardness, strength and wears
resistance. The difference composition of Nano sized alumina particles
is added 2wt%, 3wt%. The average size of aluminum and reinforcement
particle size 30µm and 100nm respectively. For Proper production of the
powder which will be placed in planetary ball mill. The sintering
Temperature and time are in the range of 550-610ºc for 60-120 min.
Forging had been involved for increasing the properties of composites at
350-400 ºc. The results that exhibited at elevated sintering
temperatures, lower porosity is obtained. Higher relative densities are
achieved at higher sintering temperature. Higher hardness was observed
in samples containing finer alumina particles. The dependence of the
diffusion to time may be explained for sintering temperature. It can be
seen that the atomic displacement is proportional to the square root of
time. This is responsible for the atomic diffusion leading to grain
coarsening. It is seen that, at higher sintering temperatures, a denser
structure is formed due to higher diffusion rates. |

Abstract: |
In most industries today productivity improvement is a major cause for
concern. This paper focuses on the logistics scenario followed by the
company, involving contractors and subcontractors. In the company, more
than 75% of the manufacturing processes are outsourced by the
manufacturer and there is no orderly or pre-planned method to
efficiently manage the logistics involved in outsourcing the required
components. To help improve the current state, a Vehicle Routing Problem
(VRP) was solved applying the existing constraints. The solution was
obtained based on the VRP concepts. ODL Studio, an open source and free
software was used to solve this rich VRP formulated. The obtained
results were integrated with a map showing the optimal transportation
sequence and the routes to be taken, thus instructing the driver on the
sequence to be followed. With a structured mathematical approach towards
the transportation problem, the total distance traveled and time taken
by the vehicle was reduced. With reduction in time, there is an increase
in the number of products that are being worked on at the manufacturer's
facility. |

periods of low demand. Faced with predictable variability, a company’s
goal is to respond in a manner that balances supply with demand to
maximize profitability. The goal of sales and operations planning is to
appropriately combine two broad options to handle predictable
variability. In this article we use aggregate planning to maximize
revenue. LINGO is used as the optimization tool. |

Title: |
Design and development of simulation based model to rank job flow
strategies |
Author (s): |
V. R. Sathish Kumar, S. P. Anbuudayasankar and M. Thennarasu |
Abstract: |
In recent days many business organizations make huge investment in
establishing their shop floors, installing most mechanized machines.
These mechanized machines ought to operate in tandem with other
machines, whose productivity level are usually different, which leads to
individual machines working in maximum efficiency and the overall shop
floor working in sub-optimal level. A spool shop assembles flanges,
valves and nozzles to lengthier pipe, which are used in the construction
of power plant, petroleum refinery, and cement plant. Longer cycle time
at different work stations, lengthier job queue waiting for processing,
high level of work-in-progress are inherent issues in a spool shop.
Individual machines operating at maximum efficiency without analyzing
the flow metrics in a spool shop leads to bottleneck. Current study,
aims at spotting and decongesting the bottle neck at various machines,
improve the output of the spool shop and optimize individual machine
utilization. Four simulation models are developed using ARENA and each
one of them are evaluated on the following metrics: output from spool
shop per time period, utilization of individual machines per time
period, value added time per unit of pipe, average queue length at each
machine, average waiting time of a pipe and work-in-progress. First
model depicts the data captured in the existing spool shop. In second
model, high priority is assigned to the jobs that ought to be further
processed in shot blasting machine and heat treatment furnace, thus
minimizing the wait time. In third model, a modification is suggested to
the existing annealing process, where the job is allowed to cool outside
the furnace, thus making the furnace available for the next job. Forth
model uses the priority rule in the suggested modified model. In all
these models, inter-arrival time of job from storage yard to spool shop
is maintained constant. Evaluating each model against performance
statistics and queue statistics helps rank models based on each metrics.
Models with high priority for further processing make use of single
piece flow, a proven lean principle technique that has enhanced the
overall efficiency. This eventually motivates practicing shop floor
manager to incorporate flow metrics in designing the layout and machine
capacity for optimal overall utilization. |

Title: |
Performance comparison for aluminium, copper and steel shots in
waste heat recovery and scrap preheating from solidifying molten metal |
Author (s): |
Mobin M. Mathew, M. Thenarasu, Aravind G. and Selvaraj J. |
Abstract: |
During solidification of molten metal in sand casting, the sensible,
latent and superheat are lost to the sand. This research article focuses
on waste heat recovery from solidifying molten metal and scrap
preheating using the recovered heat. This is done by incorporating an
intermediate heat transfer medium such as aluminium, copper and steel
shots in green sand mould. These intermediate heat transfer media absorb
the heat from the solidifying metal in the mold cavity; the heated shots
are separated from the mold and allowed to transfer their heat energy to
the metal scrap by conduction, convection and radiation. The experiments
prove that 8.4 % of heat recovery is achievable by introducing copper
shots with the green sand mold, compared to aluminium shots, which
generates 3.7 % and steel shots achieving 3 %. This method has the
potential to be instrumental in reducing the enormous amount of energy
spent to melt the metal in foundries. The experiments reveal that about
84 kWh of energy can be saved by using copper shots for melting one ton
of metal. Cumulative effect of this novel energy conservation method on
energy costs and global warming mitigation is found to be very
convincing for industrial implementation, particularly for countries
such as India. |

A collaborative application of AHP to enhance a routing model for
logistics and reverse logistics |
Author (s): |
Arun Raja A., Arjun M. and Anishkumar M. |
Abstract: |
The routing of material transport determines the efficacy of logistics
network. Due to the increased usage of plastics in the country like
India, large quantities of HDPE bottles are generated every year. HDPE
being formed from petroleum, production of new bottles cost a
significant effect to the global warming. Therefore rework of defective
bottles is necessary. The obstacles faced during the rework process are
the uncertainty involved in collection of returned bottles from
different manufacturing units, at the same time the diversity in the
variety, quantity, quality of the products. This necessitates for an
effective and well-organized reverse logistics network to return the
remanufactured products. The objective of this work is to exemplify the
role of transportation in reverse logistics for the purpose of further
improvement and to assist the HDPE bottle manufacturing industries,
having problems in efficient routing of defective goods. The proposed
model is solved using Arena optimization solver which provides the
decisions related to the utilization capability of the manufacturing
units and the allocation of the corresponding product flows. Energy
analysis of the model is also presented to find the energy of
transportation and to minimize the cost of transportation. |

Hazim Mohamad Amini, Mazlan Mohamed, Muhammad Iqbal Ahmad, Janshah
Moktar and Mohamad Azhar Ibrahim |
Abstract: |
Nowadays, the main largest energy resource is coal followed by oil and
natural gas. This phenomenon raises the public concerns to diversify the
energy sources to sustain energy availability. To address these
predicaments, biomass from agricultural residue is an important source
for renewable energy. Oil palm frond is one of the abundant agricultural
residues available from the oil palm plantation area in Malaysia.
Processing the oil palm fronds into fuel pellets are seen as an
attractive option, which is expected to reduce the amount of
agricultural residue in the plantation area. In this study, 3 portions
of oil palm fronds which are bottom, middle and top have been divided
and 2 different particle sizes which are 0.5 and 1.5 mm were used
combination with glycerin, a by-product from biodiesel production to
determine their influences on the energy properties of fuel pellets. The
glycerin was combined with oil palm fronds as a biomass binder to
enhance the energy properties with the optimum ratio of ingredients
(ratio of raw material and glycerin) for producing fuel pellets.
Proximate properties (moisture content, volatile matter, ash content and
fixed carbon) and energy content (calorific value) were conducted as the
parameters to determine the energy properties of the fuel pellets. The
glycerin content ranging from 15 to 45% (by weight), enhanced the
calorific value of the oil palm fronds’ fuel pellets from 16.73 to 22.72
MJ/kg. The results from the proximate and energy content analyses met
the fuel pellet standard requirement according to the Pellet Fuel
Institute (PFI). The highest of 22.72 MJ/kg heating value of fuel pellet
were achieved from the middle portion of 1.5 mm particle size with the
mixture ratio was 55:45; oil palm frond and glycerin respectively. In
the result, the combination of oil palm fronds and glycerin can be used
as an alternative material for biomass energy sources. |

Abstract: |
The heavy reliance on non-renewable energy sources from fossil fuel such
as petroleum, natural gas and coal has led to the scarcity of these
sources and occurrence of global warming. This phenomenon raises the
public concerns to diversify the energy sources to sustain energy
availability. To address these predicaments, biomass is among the
prominent alternative energy sources since it is renewable and possesses
minimal harms to the environment. Leucaena leucocephala, or locally
known as ‘Petai Belalang’ is one of the potential energy crops. In this
study, 3 portions of Leucaena leucocephala stem which are bottom, middle
and top have been divided and 2 different particle sizes which are 0.5
and 1.5 mm were used to determine their influences on the properties of
the samples. Proximate analysis (moisture content, volatile matter, ash
content and fixed carbon), physical analysis (specific gravity and bulk
density) plus calorific value of Leucaena leucocephala were conducted as
the parameters to determine the properties of the samples. Among the
proximate parameters, portions differ significantly (p < 0.01) in
moisture content, volatile mater and ash content except for fixed
carbon. Whereas, particle sizes shown significant differences (p < 0.01)
in moisture content, ash content and fixed carbon while differing (p <
0.05) in volatile matters. Both independent factors differ significantly
(p < 0.01) in the physical parameters, including specific gravity and
bulk density. The highest calorific value was observed in the bottom
portion with particle size 0.5 mm which is 18.56 MJ/kg, whereas
calorific values are significantly differing (p < 0.01) for both
independent factors. In conclusion, Leucaena leucocephala species show a
good result to be as potential biomass energy sources. |

Abstract: |
In recent years, a lot of researches have done by domestic and foreign
scholars to enhance and improve the development of man-made board
production that based on natural fiber and agricultural residues. Due to
a worldwide shortage of forest resources which have been excessive
cutting, man-made board production has become one of the alternative
ways to solve wood supply problems. Particle board is a panel product
manufactured under pressure from particles of wood or other
ligno-cellulosic materials and an adhesive. In Malaysia, the demand and
trend of uses wood panel product such as particle board is increasing in
the market. The purpose of this study is to identify the potential use
of cassava root as a raw material for bio-composite development. In this
research, cassava root from different ages (6, 9 and 12 months) were
used for production of bonded particle boards by using polyester as a
binder. Constant resin content, temperature, time pressing and pressure
were applied during boards’ production. Moisture content, density, water
absorption and thickness swelling test were carried out to determine
dimensional stability of the boards while static bending tests were
carried out to assess the mechanical strength of the boards.
Particleboard from 12 month cassava root gave the best results in term
of physical and mechanical properties. But, particleboard from 12 month
cassava root did not meet the ANSI/A208.1-1999 standard for
general-purpose boards. For this reason, additional research needs to be
done on improving the physical and mechanical properties produced from
different ages of the cassava root. |

Abstract: |
Residual stress classified as secondary stress that exist after all
loads been removed. Residual stress can be favorable or detrimental to
some components, depend on its type. Usually, tensile residual stress
can cause harm to components while compressive residual stress can
improve the component quality. Residual stress, either tensile or
compressive present in almost all manufactured components. Both residual
stress, either tensile or compressive can be found in welding
components. Many researchers agreed that tensile residual stress can be
found in the weld metal area, but the compressive residual stress
distribution is complex. The distribution welding residual stress varies
in different locations depends on welding parameters, types, sequence,
component type, component materials and component sizes. This review
paper provides the information of welding residual stress and their
distribution. This paper can help and giving idea to researchers on
planning their welding work with a minimum value of residual stress. |

Author (s): |
Wan Farahiyah Wan Kamarudin, Muhammad Nasri Abdul Rahman, Zildawarni
Irwan and Afifah Afnani Donak |
Abstract: |
Wastewater treatment is one of the major problems faced by textile
manufacturers as they produce large volumes of wastewater. The main
pollution in textile wastewater come from dyeing and finishing process.
The effluent that comes from textile industries not only causes
coloration of water, but also give potential to human health hazard and
a threat to aquatic life. The main objective of the study was to
evaluate and to compare the efficiency of degradation of Congo Red (CR)
dye using Fenton reagent and TiO2. The study also comprises the
influence of different experimental conditions which are the
concentration of CR dye used, the concentration of FeSO4 as catalyst in
Fenton reagent, the concentration of hydrogen peroxides (H2O2), the mass
of TiO2 and the value of the pH of the experimental solutions in CR dye
degradation. The results indicated that the photo-degradation efficiency
of the CR solution of dye was more effective when it is being treated by
Fenton reagent than the TiO2. For photo-Fenton reagent, the result
showed that the operated condition for Fenton reagent was pH under 3 (pH
< 3). As for the concentration of FeSO4 as catalyst, the optimum
concentration was at 4 x 10-5 M and the maximum removal of the CR dye
for H2O2 concentration was at 2.9 x 10-2 M with the initial dye and pH
value. As for the TiO2, the result showed less efficiency of degradation
occurred compared with the Fenton reagent in this experimental value.
The higher percentage removal of dye CR was at 0.4g of TiO2 dose and at
the pH 7 in this heterogeneous process. Additionally, the Fenton reagent
was the efficient method for pollutant removal due to the addition of
the catalyst FeSO4 where the Fe3+ ion will undergo reduction under the
ultraviolet (UV) light and through the photolysis of the H2O2 itself. |

Abstract: |
The commercial repellent product and insecticide used to repel
mosquitoes was reported to contain toxicity, caused skin irritant and
has given rise to environmental concern. In consideration of this, the
need to develop environmental friendly products is imperative to control
the mosquito attack. The means of this study are to analyze the content
of 2-undecanone (repellent agent) in the extracted Etlingera Elatior oil
of its stem, midrib, leaves and flower and also to identify its prospect
as a natural mosquito repellent. Steam distillation was chosen for
extraction of Etlingera Elatior with 2 different solvent which are
methanol and n-hexane. The characterization of the oil was analyzed
using Gas Chromatography-Mass Spectrometry. The obtained result is
2-undecanone, where the desired component was not identified in the
Etlingera Elatior plant. Despite of the absence of 2-undecanone, a great
number of different components were detected and a few of other
potential reported mosquito repellent were present such as limonene,
hexanal and dodecanoic acid in small amount. In conclusion, Etlingera
Elatior has the potential to be a natural mosquito repellent. |

Abstract: |
In
Malaysia, textile industry contributes the most to the wastewater that
has led to environmental problems. Most of the dyes used in textile
industries are toxic in nature with suspended carcinogenic and mutagenic
effect that affects aquatic lives and human beings. The focus of this
study is to identify the potential of Musa paradisiaca stem (banana
stem) which commonly available waste material that are low-cost, natural
and an eco-friendly bio-sorbent for the economical removal of methylene
blue (MB) dye in aqueous solution. In this study, the stem is acting as
an adsorbent. Batch model experiments are conducted to determine the
effect of pH and the initial concentrations of MB solutions, adsorbent
dosages and its contact time in methylene blue solutions towards the
efficiencies and adsorptivity (%) of the stem as a MB removal agent. The
stem is dried and treated with Potassium Hydroxide to remove its lignin
and to activate its cellulose part. The concentrations of MB solution
are analyses using ultraviolet-visible spectrophotometry (UV-VIS) before
and after the adsorption processes. The MB uptake has increased with the
increased of pH value. The MB adsorption increased simultaneously with
the adsorbent dosages and contact times. The maximum adsorptivity is
identified as 91.47% at 70 ppm of MB solution at pH 12 using 0.6 g of
adsorbent dosage. The best adsorbent dosage is found to be as 0.6 g due
to its higher adsorptivity in all ranges of concentration and pH of the
dye solutions. However, the removal percentage (%) decreases with the
increased of initial MB concentrations. In conclusion, this study
recommends that Musa paradisiaca can be used effectively in the
adsorption of MB in aqueous solution. |

Abstract: |
The
application of underutilized resources and eco-friendly adsorbents is
studied as the substitute for the commercially available activated
carbon which occurred at high cost. The carbon type adsorbents were
prepared from oil palm frond (OPF). It is a domestic waste that
comfortably used to eradicate basic dye, which is methylene blue (MB)
from aqueous solution using the adsorption removal method. The oil palm
frond activated carbon is used to adsorb methylene blue as one of the
effluents from the textile industry by varying the concentration, mass
of adsorbent used and contact time. The findings disclose that the most
efficient condition to remove the color intensity of methylene blue is
by using 0.4g mass of OPF activated carbon at 10 minutes of contact
time, which was tested on the lowest concentration of 20 ppm. The
results from this research have proven that the percentage removal of
dye decreases as the initial dye concentration increases. The percentage
removal on the effect of adsorbent dosage increases with the increase of
adsorbent dosage used. In overall, the findings give us hope to have a
better water quality which is free from pollution. |
