not yet developed and massive excavated and used, especially energy
solar cells and energy rainwater. The advantages of the tropical
climate, the rain and heat, should be developed on a massive scale and
the diversification of energy. Not only fossil energy is used, but the
energy that is around us. One of this rain water energy by using
Piezoelectric. The piezoelectric material capable of converting
mechanical energy into electrical energy becomes a major source of
discussion in this study. The amount of energy generated from impact of
rain water can be calculated using mechanical-electric models. The
amount of energy that can be produced depends directly on the size of
the piezoelectric membrane, the size of raindrops and frequency. As well
as solar cells used as electricity. When the two are combined energy

Abstract: |
Purbalingga, Indonesia, is regency with moderately high seism city
potential requiring compliance with planning and implementation rules
for earthquake-resistant structural systems. We evaluate the performance
of a ten-story irregular apartment building model in Purbalingga due to
the seismic load. It is necessarily conducted in order to provide
information on impacts and mitigation strategies that should be
implemented. The evaluation is performed based on seismic loads given in
the 2002 and 2012 Indonesian National Standard (SNI) using linear static
analysis, dynamic response analysis, and pushover analysis. Based on
linear static analysis, the drift ratio decreases by an average of 34.42
and 32.61% for the X and Y directions respectively. Meanwhile, based on
the dynamic response analysis, the drift ratio also decreases by an
average of 30.74 and 27.33% for the X and Y directions respectively. In
addition, the pushover analysis indicates that the performance of this
apartment building model is still at Immediate Occupancy (IO) level, the
post-earthquake damage state in which the building remains safe to
occupy, essentially retaining the pre-earthquake design strength and
stiffness of the structure. The risk of life-threatening injury as a
result of structural damage is very low, and although some minor
structural repairs may be appropriate, these would generally not be
required prior to re-occupancy. |

paths of Unity-STF SMASH sigma delta modulator architecture |
Author (s): |
Mehdi Taghizadeh and Sirus Sadughi |
Abstract: |
This
Paper presents a practical way to improve signal bandwidth and
resolution in a Sturdy Multi-Stage Noise-Shaping (SMASH) sigma delta
modulator. In this way, the processing timing issue in the critical
paths of the proposed architecture has been relaxed due to the shifting
delay of the modulator loop filter of each stage to the its feedback
path. The proposed Unity-STF SMASH architecture, which is realized with
several efficient techniques, would be robust to circuit non-idealities
such as finite op-amp DC gain. Furthermore the topology can be
implemented by a fewer active blocks, suitable it for low power, high
operation speed applications. |

Abstract: |
The
dependency of the forefront islands towards non-renewable energy
resulting in difficulty to use this energy in the future. Sungai Suci
Beach is the beach that has steep topography and high waves because it
is directly facing with Indian Ocean. Based on an initial analysis,
Oscillating Water Column (OWC) fixed on-shore tool is suitable to be
implemented in this location. This research was conducted through
collecting wind, tides, bathymetry and beach slope data. The wind data
was used for wave hindcasting using SMB method. Tide data was processed
by using Admiralty method. Based on hindcasting wave using 17 years wind
data, the average of significant wave height were 2.3 meter and periods
8.5 second with energy availability 67 %. The capacity of power that
could be generated was 1.0073 MW and categorized as small hydro. In a
review of coastal bathymetry and slope, depths ranging from 0 to 25
meters, and the cliff slope average was 74 degrees. Based on the tidal
analysis, OWC’s top side must be built taller than 1.71 meters and the
lowest side should be lower than 0.21 meters from MSL. Through this
analysis, OWC quite potential to be implemented in the Sungai Suci Beach

Green public procurement criteria for road
infrastructures: State of the art and proposal of a weighted sum
multi-criteria analysis to assess environmental impacts |
Author (s): |
L. Moretti, P. Di Mascio and A. D. Andrea |
Abstract: |
In
the last years, the attention to environmental issue is growing,
demonstrating the interest to protect the nature and to better use the
non-renewable resources. At international level, and especially in the
European Community, for different trades, a wide production of voluntary
documents and institutional acts proves the interest and the need for a
green economy. An innovative approach may lead to the experience of
Green Public Procurements (GPP), in order to protect the environment as
a public interest and to promote technological developments. So far the
experiences of GPP are limited, not entirely positive and in the field
of road infrastructures almost entirely absent. Construction and
maintenance of road infrastructures is objectively more complex than
purchasing goods or services. The paper proposes the integration of the
weighted sum multi-criteria analysis into existing procedures. The
methodology needs for environmental labels related to materials,
machines and works which contribute to the final product “road”. The
labels are recognized at international level and consistent with
procedures, conditions and criteria currently published in road tenders,
therefore the approach can be followed to pursue the environmental
sustainability of road infrastructures without compromising the economic
attention. |

Author (s): |
Thishya Varshitha U. and Balamurugan K. |
Abstract: |
In
recent years there has been a considerable growth on the integration of
various renewable sources and multi types of flexible ac transmission
systems (FACTS) in many practical power systems in the world. Hence the
Distributed Generation is implemented in terms of using renewable
source. The major problem faced in distribution network is power loss
reduction and finding the proper location of distributed generation
(DG). The main aim of the project deals with optimal placement of
Distributed Generation with considering the Flexible AC Transmission
Systems (FACTS) devices in order to minimize the total real power loss.
This paper aims at improving the voltage profile in the Distribution
network by optimally placing the DG with and without FACTS devices
(SVC). The optimal placement of DG is done based on Voltage Stability
Index. The simulation studies of proposed test systems are performed in
MATLAB coding. The outcome of the coding shows that there is an
improvement in the voltage profile and also there is minimization in
power loss of the distribution system. |

Abstract: |
Modal
Analysis is a common practice to define parameters of structure under
scientific view. Experimental Modal Analysis (EMA) is a well-known
procedure to determine modal parameters. The usage of piezoelectric film
sensor as viable and cost-saving device is indeed a need in this advance
and sophisticated era. An experiment is conducted to determine modal
parameters of aluminum 6061 (Al6061). Here, a free dynamic vibration
analysis is conducted to obtain the parameters. Al6061 is chosen as the
experiment component because of its wide application in manufacturing
industries. Theoretically, if the component vibrates and produce
frequency coherence with the natural frequency, resonance frequency will
occur which can lead to structural failure. Modal analysis study is
conducted by using both simulation and experimental methods. Simulation
is conducted via ANSYS software while impact hammer testing is done for
experimental work. Piezoelectric film and accelerometer are used as the
sensor. The result obtained from simulation showed that frequencies for
mode shape 1, 2 and 3 for square shape are 191.89Hz, 542.34Hz and
766.18Hz. The result gained from accelerometer showed that frequencies
for mode shape 1, 2 and 3 for square shape are 195.00Hz, 557.00Hz and
865.00Hz. The result captured from piezoelectric film sensor appeared
that frequencies for mode shape 1, 2 and 3 for square shape are
205.33Hz, 609.33Hz and 904.33Hz. The result obtained from simulation
showed that frequencies for mode shape 1, 2 and 3 for circle shape were
134.60Hz, 324.73Hz and 727.52Hz. The result obtained from accelerometer
showed that frequencies for mode shape 1, 2 and 3 for circle shape were
158.67Hz, 421.33Hz and 625.00Hz. Finally, the result captured from
piezoelectric film sensor appeared that frequencies for mode shape 1, 2
and 3 for circle shape were 141.00Hz, 321.00Hz and 504.33Hz
respectively. The equation of gradient for accelerometer and piezofilm
is ya = 316.42x – 104.13 and yp = 309.63x – 43.20 respectively.
Therefore, the relationship between the natural frequency of
accelerometer and piezofilm for the square-shaped specimen is ya =
1.02yp – 59.98. The equation of gradient for accelerometer and piezofilm
is ya = 270.55x – 134.82 and yp = 280.89x – 215.04 respectively.
Therefore, the relation between the natural frequency of accelerometer
and piezofilm for the circle-shaped specimen is ya = 0.96yp + 72.3. Both
result showed the regression ratio of 1.02 and 0.96 which is
approximately 1.0 and there was a good results agreement between
simulation and experimental outcome. |

An overview on state-of-art and future
application fields of BLDC motors: Design and characterization
of a PC-Interfaced driving and motion control system |
Author (s): |
Paolo Visconti and Patrizio Primiceri |
Abstract: |
New
generations of equipments must have better performances respect to the
previous generations, such as higher efficiency, low power consumption,
reduced electromagnetic interference, small dimensions, lightness and so
on; all these improvements must be achieved while maintaining, at the
same time, systems cost as low as possible. Brush-Less Direct Current (BLDC)
motors, employed even more in the last years in many equipments in
various application fields, present low maintenance costs, compact size,
high reliability, efficiency, low power consumption and other optimum
features, proposing themselves as excellent candidates for satisfying
the stringent requirements mentioned previously. In this paper, after a
detailed overview on the current and possible future application fields
of BLDC motors, from home appliances, to automotive, industrial
automation, medical equipments and robotic instrumentation, the design
and realization of a driving and control system of a BLDC motor, with
Hall sensors embedded, is presented. A BLDC motor is provided by
permanent magnets on moving part (rotor) and windings on fixed part
(stator); energized stator windings create electromagnetic poles and the
rotor (equivalent to a bar magnet) is attracted by the energized stator
phase. By using appropriate sequence to supply stator phases, a rotating
field on stator is created and maintained. The lead between rotor and
rotating field must be controlled to produce torque and this
synchronization implies accurate knowledge of rotor position which is
obtained by means of the embedded Hall effect sensors. The realized
driving system is composed by three principal blocks: the control
electronic board, the power driving board and the BLDC motor. By PC
connected via USB with the driving board, the user can choose the motor
rotation direction, set the desired rpm value and, by varying
potentiometer value located on board, change the rotation speed.
Different tests were performed for verifying the correct motor operation
and the results show that all the employed devices, driving board,
control board and BLDC motor, work properly. |

evolutionary algorithm for MANETs |
Author (s): |
R. Thanuja and A. Umamakeswari |
Abstract: |
Network security is one of the primary concerned now days for large
organizations. MANETs are deployed in challenging real-world
environments for example, disaster management, civilian emergency
operation and unmanned aircraft operation. Providing Security in this
type of environment is the most challenging problems as the operation
environment of such network is usually is difficult to decide. This will
lead to any malicious activity that will affect the operation of the
networks. Various modifications are being applied to IDS regularly to
detect new attacks to handle them effectively. In this paper, we have
designed a effective Intrusion Detection System (IDS) to detect the
attacks in a MANET that uses modified fuzzy min max neural network in a
effective manner. The aim of the proposed work is to improve the
detection accuracy ratio and reduce the false positive rate. IDS is
designed as a two phases technique, in which the first phase use the
fuzzy min max neural network algorithm to train 60% data and test 40%
data of the network. In the second phase, the modified fuzzy min max
neural network algorithm is applied to 60% of train data +20% test data
to form a new train data set and test the remaining 20% data collected.
The proposed two phase intrusion detection method was evaluated using
KDD cup data set. The experimental results showed that the proposed
method is better than the other methods in terms of the detection rate,
accuracy and reduced false positive rate. |

characteristics during turning using deform 3D |
Author (s): |
R. Rajesh, J. Lilly Mercy, S. Ravikumar
and Akanksha Singh |
Abstract: |
Titanium and aluminium alloys are ubiquitously used in aerospace,
automobile, chemical and medical applications due to their innate and
characteristic properties of high strength to weight ratio, specific
strength at elevated temperatures, corrosion and chemical resistance,
creep and fatigue strength etc. Manufacture of accurate precision
components from titanium alloys is a daunting task as the alloys are
difficult to cut material due to the ingrained microscopic as well as
macroscopic qualities such as low thermal conductivity, low modulus of
rigidity, work hardening, high chemical reactivity with tool, built-up
edge formation etc. during machining processes. Turning is one of the
most widely used manufacturing techniques for producing circular shape
from irregular shape in the real time industry applications and there
are a large number of parameters to be investigated in this process.
Predictions of important process variables of turning such as
temperature, cutting forces and stress distributions play significant
role on designing turning process parameter and optimizing cutting
conditions. Therefore finite element deform 3d (FEA) and simulation
comes as a handy tool to calculate and analyse the tool wear rate which
in turn helps us save time and also leads to less material wastage. The
tool bit base metal used is tungsten carbide over which a coating of
three different materials namely Ti, Al2O3 and TiCN has been applied.
Four factors that are -material, federate, speed, and depth of cut were
taken into considerations at three different levels to get nine
experiments which was then optimized by taguchi method to infer and
analyse the best suitable parameter and condition for least amount of
tool wear during turning operation. |

Abstract: |
Rain
has deleterious impact on satellite signal propagation above Ku-band due
to scattering and absorption. Numerous Empirical and Non-empirical
models are evolved based on measured statistics to estimate the rain
attenuation. The day wise, monthly and yearly analysis for 3 years of
data is performed in Vaddeswaram. Of the available models, for the
tropical region, ITU-R model which uses bulk recorded database clearly
underestimates the value. In this paper different attenuation models
like ITU-R, RH, SAM and Moupfouma are studied and the results are
compared with measured values and analyzed to determine the suitable
model for one of the tropical region Vaddeswaram, A.P. It is observed
that the average attenuation is around 13.5dB in a year and Moupfouma
model is best suited for this region. |

Behavior change in peat stabilized with
fly ash and lime CaCO3 due to water infiltration |
Author (s): |
Noor Endah Mochtar and Faisal Estu
Yulianto |
Abstract: |
Stabilization method for fibrous peat is more beneficial than other soil
improvement methods; it is cheaper and environmental friendly.
Therefore, it has been developed continuously to obtain the optimum
results. The previous study shows that 10% of admixture (lime CaCO3+fly
ash) causes bearing capacity of the stabilized peat increases and its
compression decreases. However, the study was carried out without
considering the field condition where the area of stabilized peat was
only as wide as the area that will be built. It means that the
surrounding of the stabilized peat is still the original peat with very
high water content. Consequently, water from the original peat will
infiltrate into the stabilized peat area which has smaller voids and
lower water content. Based on this consideration, the study was carried
out to check the effect of water infiltration to the behavior of
stabilized peat. This field condition was imitate in the laboratory
model by putting the stabilized peat in the middle of the original peat.
The admixture (lime CaCO3+fly ash) used was 10% and the stabilized peat
parameter was observed until 180 days. The results show that behavior of
stabilized peat w/o-infilt improve rapidly because formation of CaSiO3
gel is faster; however, in short curing period (90 days), its shear
strength drops drastically and its compression becomes bigger. On the
other hand, CaSiO3 gel formation of stabilized peat w-infilt is slow due
to CaSiO3 gel formation is disturbed by water infiltration. As a result,
its behavior improves slowly and the optimum results of the stabilized
peat w-infilt reaches when the curing periods longer than 120 days. It
also figures out that water infiltration gives a good effect to the
behavior of stabilized peat. |

restructured power system with facts devices |
Author (s): |
K. Chandrasekar, B. Paramasivam and I. A.
Chidambaram |
Abstract: |
This
paper presents evaluation of Power System Restoration (PSR) Indices
based on the Automatic Generation Control (AGC) assessment of two-area
thermal reheat power system with FACTS devices in a restructured
environment. These PSR indices indicate the ancillary service
requirements to improve the efficiency of the physical operation of the
power system with the increased transmission capacity in the network. In
this study, a new control strategy the Proportional and Integral plus
(PI+) controllers are designed using Krill Herd (KH) algorithm for
solving AGC problem in power system. The PI+ controller uses a low-pass
filter on the command signal to remove the transient’s response over
shoot. In this way, the integral gain can be raised to higher values and
PI+ controller is useful in applications for AGC loop. The recent
advances in power electronics have led to the development of the FACTS
devices such as Thyristor Controlled Phase Shifter (TCPS) and Static
Synchronous Series Compensator (SSSC) are capable of controlling the
network condition in a very fast and economical manner. The proposed PI+
controllers are designed and implemented in two-area unequal
interconnected reheat thermal power plants with FACTS devices are
considered for simulation study and their optimum settings are obtained
using KH algorithm employing Integral Square Error based fitness
function. From the simulations results, the incorporation of FACTS
devices can enhance the total transfer capability and decrease the line
congestion and to ensure improved PSR Indices in order to provide good
margin of stability. |

Lyubov Ivanovna Nikitina |
Abstract: |
We
need to know the magnitude of the forces acting on rolling drilling bit
to assess reliability and durability of cutting structure of rolling
drilling bits and datum mode of roller bit. There is a brand new
measuring device that allows measuring the amount of force on each tooth
of each roller bit in cooperation with nondestructive bottom hole,
consisting of concentric steel rings, divided into two sectors. There
was made a skid for realization of this method, which was intended for
rolling drilling bit under pressure in bottom hole of measuring device.
There is a method for measurement of forces, which effects on elements
of rolling drilling bit. There is a substantiation about choice of
object of research and results of made experiments and its statistical
processing minimum required length of one test was determined and number
of repeats of each test to obtain reliable results at a given confidence
level and permissible measurement error. There was made an analysis,
which showed cooperation schemes of one crown to bottom hole, and on the
basis of which it was concluded that axial components of forces have a
greater impact on the durability of drilling bit cutting structure than
tangential. Therefore, only axial components were evaluated in selection
of test mode. Optimal ranges of axial loads on bit and bit speeds were
determined, and that allowed getting an objective picture of
distribution of forces on drilling bit cutting structure. Developed
method with using a computer allows getting a large amount of reliable
information very quickly about how to download all elements of equipment
of rolling drilling bits of various sizes in order to optimize the
design of their cutting structure and gauntries. |

Locker system: development of intelligent
surveillance using secure One Time Password and face recognition |
Author (s): |
B. Srikar, N. Anusha and A. Darshan Sai |
Abstract: |
Present day locker systems are not highly secured. In order to overcome
the various security issues proposed a locker system using latest
technologies like IoT (Internet of Things) coupled with Facial
recognition system and generation of OTP (One Time Password). IoT is one
of the latest technologies where the various smart electronic devices
are connected using the internet with the help of sensors, actuators in
order to exchange information. Face recognition system is another
application which ensures that only authentic user gets to access the
locker by ensuring verification of facial features. To access the
locker, the user has to type the locker PIN (Personal Identification
Number). The camera module is initiated for the facial recognition after
the verification of pin is validated. Using Viola Jones Algorithm an
efficient face detection system is developed. Extractions of facial
features are being carried out efficiently using GLCM (Grey Level
Co-occurrence Matrix), HOG (Histogram of Oriented feature Gradient), and
Gabor Filter techniques. After verifying the authentic user an OTP is
sent to the registered mobile number. If any of the credentials do not
match then the system will capture the intruder’s face and
simultaneously an email and a SMS (Short Message Service) will be sent
to the registered mobile number through which one can inform to the
police. |

Abstract: |
For
the present, it has been dispensed with the traditional ways using
modern methods in a lot of practical industries that require a more
accurate control. In this paper, a Fuzzy logic has been applied to
control the important variables of steam turbine in AL Dura station in
Baghdad that generate (160MW). These controlled variables are pressure,
temperature, speed and humidity. Fuzzy requires a data which obtained
from actual power plant. This work explains the control on turbine
stages during operation in order to make a right decision if any faults
occurred during these stages at limit conditions based on fuzzy system.
It was used simulation of Fuzzy system in MATLAB program (V 2014 a). The
interest of the fuzzy controller that it is fundamentally based on the
practical experience of engineer for putting specific values must be
appropriate for the system's work within the normal operating limits for
control via fuzzy logic and make a right decision when a problem occurs. |

Author (s): |
A. Hadi Fikri A. H., Paulson E. N., Rozeha
A. Rashid, Kamaludin Mohamad Y. and Mohd. Adib Sarijari |
Abstract: |
During emergencies, a number of rescue teams come to the field and setup
their own radio communication systems. If the deployed communication
setup does not coordinate among themselves properly, they may interfere
with each other when using the same RF channels known as co-channel
interference. Spectrum sensing is the most important and complex job for
cognitive radios. Cooperation among cognitive radio nodes is needed to
enhance the sensing performance. In this paper, we present an
experimental study of this solution. A Software Defined Radio comprising
of GNU Radio and USRP were used to capture the signal samples to build a
database profile of the spectrum condition. MATLAB communications
toolbox was used to analyze the data and examine the spectrum pertaining
to the condition in emergency networks. The benefits of cooperative
spectrum sensing in avoiding co-channel interference during emergency
situations are illustrated. Cooperation among cognitive spectrum sensing
nodes operating at the same frequency improves the probability of
detection, and the overall efficiency of the system. Results show that
the cooperative sensing scheme outperforms the individual sensing
approach. It can increases the probability of detection relative to the
collected samples as the key performance indicator. |

Abstract: |
Groundwater, which is both a part of subsoil and part of total water
resources, is a valuable mineral, the use of which in the economy and
social sphere, and mainly for household and drinking water supply of the
population, is increasing every year. At the moment, the Russian
groundwater resources management system is imperfect, as the regulatory
methods used have a number of significant problems that limit the
optimal course of the processes of studying, extracting and using such a
valuable resource as water. Accordingly, the optimization of the
production and use of groundwater requires significant changes in the
field of the organizational and economic mechanism. As a result of the
analysis of the tax legislation of the Russian Federation in the field
of regulation of the commercial use of underground mineral medicinal and
potable water, the main problems were identified and rational ways of
their solution are proposed. |

automotive sectors because of its lightweight, high-temperature
strength, and high corrosion resistance. This research paper
investigates the influence of machining variables on the surface
roughness of the machined component in finish turning of titanium alloy
Ti-6Al-4V. The finish turning experiments conducted on GEEDEE WEILER CNC
lathe at different speeds (v), feed (f) and depth of cut (d). Uncoated
tungsten carbide insert was used as the cutting tool. Taguchi L9
orthogonal array utilized to perform the experiments. After conducting
each test, surface roughness measured using surfcom tester. The optimal
machining variables that provide the smaller value of surface roughness
is determined based on signal to noise ratio method. Analysis of
variance (ANOVA) was accomplished to identify the most affecting
machining variable on surface roughness. The experimental result shows
that the feed was the most dominant variable that influences the surface
roughness. From the ANOVA, the surface roughness in finish turning is
strongly influenced by the feed rate followed by speed and depth of cut.
The minimum surface roughness was obtained by the following optimal
variables via speed 75 m/min, feed rate 0.1 mm/rev and depth of cut 0.25
mm. |

G. Sasi Bhushana Rao |
Abstract: |
In
the present world the death rate due to cancer, a malignant tumour is
increasing day by day. Therefore, cancer detection is a challenging task
to the doctors to detect it, in the preliminary stages. This detection
can be done by identifying the tumour whether it is benign or malignant
with help of Magnetic Resonance Imaging (MRI). In this paper, the MRI
slices are segmented and then they are reconstructed to into 3D for
better understanding the stage of tumour. First the MRI images are
preprocessed and a new heuristic algorithm based on
Expectation-Maximization, Histogram and object based thresholding
methods is developed to identify the cancer wherein the resultant of the
algorithm is 2D. For better understanding of the cancer stage these 2D
images are combined to form a 3D view of the tumour. The performance of
these hybrid fused techniques will be compared in terms of quality of
the resultant tumor. |

Abstract: |
An
Experimental study was conducted to investigate the compressive strength
of lightweight polystyrene sandwich blocks. Eight blocks were subjected
to compressive strength by using combination of cement, weld mesh,
Thermocol and sand. Four blocks in single mesh and other four blocks in
three web mesh with combination of M, V and U Pins. The test results of
control block i.e. single mesh block without pin was compared with other
specimen show that lightweight aggregate concrete blocks (400mm X 200mm
X 100mm) offered higher compressive strength of 4.12MPa at 28 days. The
density of foamed-concrete is found to be 1200 kg/m3. Hence there is a
reduction of dead load, faster building rates in construction and lower
haulage and handling costs. |

An advanced IWD based Hyper-heuristic
workflow scheduling in computational grid |
Author (s): |
S. Gokuldev, C. Sowntharya and S.
Manishankar |
Abstract: |
Grid
computing paved way for efficient utilization of resources and this is
one of the important aspects in the recent research trends. In this
paper, an Intelligent Water Drops (IWD) algorithm is proposed for task
workflow scheduling with hyper-heuristic search for achieving better
performance optimization for workflow distribution in computational grid
environment. The challenge is to find the best matching resource among
the available free resources for which a grid broker is used. A hyper
heuristic search is performed which undergoes multiple rounds of
searches for finding the best matching resource by imparting a specific
point in time rule. Load balancing is achieved by computing the average
computational power of all the resources and grouping the resources.
This helps the system to assign various types of jobs to the resources,
thus improving the computational efficiency. The performance parameters
such as makespan, cost, deadline of jobs and number of searches for
finding best optimal resource are considered for performance
enhancement. The simulation results of Intelligent Water Drops based
Hyper-heuristic algorithm is compared with few of the latest existing
works and the proposed algorithm outperforms thus achieving performance
optimization. |

Boundary optimization of Ground Glass
Opacity in CT images of lung cancer |
Author (s): |
Saravanan S., Selvakumar G., Amarnath C.
and Manikandan S. |
Abstract: |
In
computer aided diagnosis, pre-processing, segmentation, feature
extraction and classification are the steps involved. For segmentation
the boundary must be defined to get regional information inside the
boundary. Ground Glass Opacity (GGO) has ill-defined boundary. Hence,
there is a necessity to optimize the boundary of GGO. Once the boundary
is optimized, feature extraction and classification of malignant and
benign of the particular GGO becomes easy. Using Distance Regularized
Level Set Evolution (DRLSE) and Active contour without edges
independently, the contour is grown and compared with the model image.
The model image was created using the expertise of a Radiologist,
applying Mattes Mutual information method. The contour which gives
maximum mutual information is concluded as the optimized boundary.
Wavelet transform has already been proven its application in identifying
pits and cracks of corrosion metals. The same analogy is applied in GGO
so that the partly solid and liquid GGOs can be precisely classified as
malignant or benign. After optimizing the ill-defined boundary of GGO
features of wavelet transformation were extracted along with textural
features of mean and variance. Skewness and kurtosis were neglected
since they were negligibly small. It is shown that on comparing the
growing contour with model image using mattes mutual information, the
DRLSE method shows greater results, without leaking compared to Active
contour without edges. After extraction of features from wavelet
transformation and textural features classification as malignant and
benign was done using learning vector quantization (LVQ). On finding the
optimized boundary, it is easier to classify the ground glass opacity as
diffuse finding or local finding. Hence taking two images where one is
taken as malignant and other as benign classification was done as benign
and benign by the classifier. The malignant have been identified as
benign due to minimum number of images used in training. |

Frictional effect and load carrying
capacity in porous inclined multi stepped composite bearings with couple
stress fluids |
Author (s): |
Nisha and Sundarammal Kesavan |
Abstract: |
This
paper presents the frictional effect and load carrying capacity in
porous inclined multi stepped composite bearings with couple stress
fluids. The most general form of the modified Reynolds type equations
derived for the squeeze film lubrication of the porous inclined multi
stepped bearings and an expressions for pressure distribution, work load
and frictional force is mathematically derived. These expressions can be
utilized to obtain the performance characteristics of different types of
geometry under consideration. The important parameters for discussing
the behavior of bearing characteristics are the couple stress parameter
, the percolation parameter ‘ß’ and the permeability parameter. The
global system of equations was obtained for the bearing and solved using
MATLAB iterative scheme. It is observed that there is a significant
increase in the pressure distribution this will lead to an increase in
load capacity for fluids with couple stress in comparison with Newtonian
fluids and the coefficient of friction for inclined stepped composite
bearing compared to other geometries. According to the results, the
couple stress fluid as a lubricant improves the squeeze film
characteristics and results in a longer bearing life. |

Power factor correction converters for
BLDC motor drive system: A comparative evaluation |
Author (s): |
P. Sarala, S. F. Kodad and B. Sarvesh |
Abstract: |
AC to
DC conversion with the help of power electronic converters is very much
used these days in many applications. Rectification of input supply is
essential in many areas of engineering especially in motor drive
applications. BLDC motor is fed with DC supply and need a rectifier to
convert available AC supply to DC type. Rectification from input AC
supply to DC output with simple diode bridge rectifier insists for an
output capacitance for stiff DC output. The presence of capacitance at
the output of DC side deteriorates source power factor and reduced power
factor at source side can cause serious problems in the system. This
phenomenon insists for power factor correction. Power factor correction
using DC-DC converters is a general practice. This paper presents a
comparative evaluation of different types of power factor correction
converters for BLDC motor drive application. Power factor correction
converters like current follower Buck converter, Bridgeless Buck
converter and Hybrid Buck converters were presented in this paper for
evaluation. The Simulink models and results are developed using MATLAB/SIMULINK
software. Power factor angle between source voltage and source current
was presented with all three converters and THD in stator current was
also depicted. |

Design and analysis of novel high
performance CMOS domino-logic for high speed applications |
Author (s): |
Rajesh Kumar Patjoshi, Suvarsha, S. K.
Irfan Ali, S. K. Mastan Basha and D. Anjum |
Abstract: |
Dynamic logic style is popular due to its fast processing speed and less
power dissipation in high performance circuit design as compared to
static CMOS logic style. However, dynamic logic has less noise tolerance
and charge sharing problems and hence it is not widely accepted for all
high speed applications. As a consequence, a domino logic circuit is
proposed for applications such as high-speed adder, comparator and
arithmetic and logic unit (ALU) design. Furthermore, the proposed domino
logic circuit provides multi standard advantages such as less
propagation delay, less power dissipation and high fan out capability.
The proposed circuit is simulated and tested in T SPICE with 45 nm
technology. Moreover, it is compared with other domino logic circuits in
terms of power dissipation and propagation delay. |

Abstract: |
What
you do today determines your tomorrow; not having an efficient disposal
strategy today will lead to a trashy tomorrow. Noting and implementing a
robust mechanism for disposal is what this paper aims at. This project
works on an integrated sensing system which involves gathering details
of parameters that help us in being aware of the condition of dustbin
using sensors and updating the inputs received from the sensors to an
IOT based server using Raspberry-pi so that that the information can be
accessed from any remote device by waste handlers and from the
information received by the waste handlers help them decide whether a
particular area needs immediate cleaning or not and also if an area
needs extra litter bins to be placed nearby or removal and relocating
existing litter bins to other places where they are needed so as to
handle waste effectively. Dustbins are fixed with sensors which are
further interfaced with microcontroller and based on the information
received from sensors it notifies the status of the bin to the municipal
corporation. This results in automation of the process of waste
management. The data thus collected can also be used in data analytics
which helps in the precise estimation of the condition of bin
beforehand. |

Abstract: |
This
study focuses on the effects of colloidal nanosilica (nS) on fresh and
key hardened properties of SCCs in comparison with similar replacement
values of the commonly used microsilica (mS). Two types of portland
cement with low (type V) and moderate (type I) tricalciumaluminates
(C3A) and three percentages of cement replacement with nS or mS.
Fourteen concrete mixes were evaluated for flow, T50, V- funnel, J-ring
and L-box as workability measurements; and compressive strength,
splitting tensile strength and chloride resistance as hardened
properties. Fresh properties results reveal that with equivalent
percentages of cement replacement and super-plasticizer added, colloidal
nS shows lower workability measurements compared to that of mS. This
observation is consistence for both types of cement used. The use of nS
enhanced all concretes compressive strengths compared to mS and control
mixtures. The improvements were a function of nS dosages used. The
enhancements in splitting tensile strengths, however, were more
pronounced at lower nS dosage of 3%, which reflect the sensitivity of
tensile properties to the binder replacement effects. The remarkable
improvements in chloride resistance performance for concretes contained
nS, correlate with the compressive strength results and indicating for
better pore structure characteristics. |

Abstract: |
In
recent years, the world has seen a lot of progress in automated home
systems. The existing home automation systems are basic: turning
switches on/off, etc. over the Internet. But this leaves a lot to be
desired in the Home Security department. While there are systems that
let you view your security camera feed, this is highly time consuming
and counter-productive. Pressing of buttons also needs to be replaced
with a voice-to-text and a text-to-voice feedback system to enable ease
of access. Also, using the Internet servers to control devices makes the
systems prone to server-related issues like lag when the servers are
overloaded, etc. Hence, there is a need to access the devices in Real
Time. This paper deals with all of the above mentioned issues. It deals
with the idea of using PubNub Networks as a real time operator, and
using facial recognition interfaced with the Face book account of the
home owner to make the surveillance of homes more time saving and
accurate, and usage of a mobile application-based interactive feedback

Author (s): |
S.
Madiwale, A. Karthikeyan, V. Bhojwani and S. Chougule |
Abstract: |
Non
conventional, alternative and as different energy source of energy,
biodiesel attracted many scientists and researchers to consider him as
an alternative fuel for automotive sector in last few years by large.
Biodiesel is an oxygenated fuel, which contains 10 % to 11% oxygen, no
aromatics, higher cetane number and reduce harmful pollutants from
engine exhaust. Higher viscosity, higher flashpoint, poor cloud point,
poor pour point and poor cold filter plugging point of pure biodiesel
limits its direct usage as fuel in the diesel engine. So it is required
to prepare the blend of biodiesel /diesel with addition of ethanol as an
additive in order to improve hot flow and cold flow properties of the
blend. Improved hot flow and cold flow properties will enhance engine
performance, combustion and exhaust emissions. In the present study
feedstock of cottonseed biodiesel/diesel blend is used as fuel with the
addition of 5% of ethanol as an additive. Blend properties were
investigated as per IS 1448 standards. Experimental investigations were
carried out on single cylinder diesel engine with eddy current
dynamometer. Experimental investigation shows that addition of ethanol
improves kinematic viscosity by 7% .cloud point by 9%, and pour point by
10% but density was increased by 3% and calorific value decreased by 9%
.Engine performance , combustion characteristics and reduction in
emissions , are improved drastically by addition of an ethanol as an
additive in the cottonseed biodiesel/diesel blend . Improved hot flow
and cold flow properties , improved combustion , improved performance
and reduced emissions proves that cottonseed oil biodiesel/diesel blend
with ethanol as an additive stands as an alternative fuel for diesel
engine. |

Sundar S. |
Abstract: |
The
aim of this project is to reduce number of wires in vehicle and alert
the driver of blind zone collision. Because of the expanding number of
sensors sent in current vehicles, intra-vehicular remote sensor systems
(IVWSNs) have as of late gotten a great deal of consideration in the car
industry, as they can diminish the measure of wiring tackle inside a
vehicle. By evacuating the wires, auto producers can diminish the
heaviness of a vehicle and enhance motor execution, mileage, and
dependability. Notwithstanding these immediate advantages, an IVWSN is
an adaptable stage that can bolster other vehicular applications too. An
illustration application, known as a side visually impaired zone caution
(SBZA) framework, which screens the visually impaired zone of the
vehicle and cautions the driver in a convenient way to avoid impacts, is
talked about in this paper. The execution of the IVWSN-based SBZA
framework is assessed through genuine investigations led on two test
vehicles. Our outcomes demonstrate that the proposed framework can
accomplish roughly 95%-99% location rate with under 15% false alert
rate. Contrasted and business frameworks utilizing radars or cameras,
the primary advantage of the IVWSN-based SBZA is significantly lower
cost. |

Abstract: |
Indonesia is one of the countries categorized as developing countries
with increasing demand for transportation, in which the people prefer
using private transportation for its convenience and punctuality.
Meanwhile, one of the efforts to overcome the problem with public
transportation is by operating Bus Rapid Transit (BRT). Indeed, Jogja
has a BRT called Trans Jogja. The implementation of Bus Rapid Transit (BRT)
itself requires a performance evaluation, by exploring the service
quality. Strategic priorities for the implementation of Bus Rapid
Transit (BRT) management are needed in optimizing the performance of BRT
in Jogja. The findings of this study reveal that the better the
management of BRT is, the more the performance of BRT will directly
improve. The better the policy of BRT is, the more the performance of
BRT will directly improve. The better the quality of BRT management is,
the more the quality of BRT service will directly improve. The better
the policy of BRT is, the more the quality of BRT service will directly
improve. Improving the quality of BRT management and policy will
directly enhance the performance of BRT and indirectly will affect the
improvement of the service quality. |

Abstract: |
This
paper is the first to demonstrate and simulated a simple and systematic
transfer matrix (T-matrix) method for analyzing the accumulated effects
of Rayleigh Backscattering (RB) and Fresnal reflection (FR) crosstalk on
signal transmission in bidirectional single-fiber WDM-PON systems for
the conventional (usually 20 km transmission without any amplification
in remote node) and comparing with the analytical methods. Secondly by
using analytical method we are going to analyse the three cases for
long-reach WDM-PONs (100km by utilizing optical amplifier to enhance the
power budget) in the first case the best crosstalk-to-signal (C/S) is
achieved when the Remote Node (RN) is placed either near to the Central
office (CO) or Optical Network Unit (ONU) section. And in the second
case, we are going to achieve the best effective crosstalk-to-signal
(C/S) ratio when the Remote Node (RN) gain is placed at the middle of
transmission link. And in the third case, the crosstalk-to-signal (C/S)
ratio gets worse nearly by 1.5 dB in the presence of a strong reflection
(r = 30 dB). Eventually if the FR is increased by the smaller
reflectivity and therefore EDFA gain must be exaggerated, the
crosstalk-to-signal (C/S) ratio will even get worse when EDFA is placed
near to ONU section. This happens due to the reamplification and
re-modulation feedbacks of back reflections that may occur in the
Transmission of the signal at Remote Node (RN). This transfer matrix
method is efficient, powerful (when comparing with the analytical
methods). Its accuracy is verified for straight forward system
architectures and then applied for complex architectures of long-reach
hybrid WDM-PONs. |

the hunt of low carbon gas for cleanser environment - these are the
motive researchers are seeking out options of fossil fuels. Renewable,
non-flammable, biodegradable, and non-toxic are a few reasons that are
making biodiesel as a suitable solution to update fossil-gas in close to
future. In latest years, in many nations of the sector manufacturing and
use of biodiesel has gained popularity. On this research, biodiesel from
Jatropha curcas oil and Calophyllum inophyllum oil has been produced the
use of the transesterification technique. Properties of the produced
biodiesels have been compared with the BIS15607: 2005 standard:
biodiesel well known and trying out techniques. Density, kinematic
viscosity, flash point, cloud point, pour point and calorific fee, these
are the six important physicochemical houses that were investigated.
Each Jatropha curcas biodiesel and Calophyllum inophyllum biodiesel have
been within the popular limits, so that they both may be used as the
alternative of diesel gas. Moreover, engine overall performance and
emission parameters of a diesel engine run by both Jatropha
curcasbiodiesel–diesel and Calophyllum inophyllum biodiesel–diesel
blends were evaluated at excessive idling conditions. Brake precise
gasoline consumption accelerated for each the biodiesel–diesel blends
compared to natural diesel gas; but, at maximum idling circumstance,
this increase became almost negligible. Exhaust gasoline temperatures
decreased as mixture percentages expanded for each the biodiesel–diesel
blends. 20% Calophyllum inophyllum biodiesel-diesel blends emitted

collection and processing to form control signals and transfer them
without loss and distortion to actuators in order to achieve efficient
operation of the technological line for the concrete twin-layer paver
and block production. |

Abstract: |
The
proposed antenna is a transparent water dense dielectric patch antenna
which is fed by an L-shaped probe. The operating mechanism of the
proposed antenna is similar to the standard metallic patch antenna. A
study reveals that the gain of the antenna can be increased if the water
patch is brought close to the L-shaped probe but the distance between
the water patch and the L-shaped probe should be at least 1 mm. A
maximum gain of 7.3 dBi, return loss of 18.4 dB and impedance bandwidth
of 575 MHz was achieved. It had symmetrical unidirectional patterns. |

Abstract: |
Roseaneath and Murteree shale in Cooper basin, South Australia are
proven seal, source as well as shale gas reservoir rock. Source rock
characterization as a potential gas requires extensive understanding
about the geomechanical properties for optimization of stimulation
treatment and in order to avoid well bore instability and sand
production during drilling and completion stages. Fifteen samples were
selected from Moomba 191 well (depth 8473--8475 ft) drilled in Cooper
Basin by DSD, Australia. The Triaxial compression and unconfined
compression tests were performed on samples in order to find static
geomechanical properties. The wireline logs like sonic and density were
used to find dynamic mechanical properties. The calibrations were
carried out between static and dynamic parameters in order to get
reliable calibrated values. The 1-D Mechanical Earth Model (MEM) was
developed based on elastic parameters (Young’s modulus, Poison’s ratio),
failure parameters (Cohesion, internal friction angle, compressive
strength and tensile strength), in-situ stresses, pore pressure and mud
weight. The calibrated Young’s modulus and Poison’s ratio were ranging
from 15 GPa to 30 GPa and 0.20 to 0.3 respectively. Brittleness analysis
(BI) (ranges from 0.2-0.78) exhibited brittle and ductile layers within
the whole shale interval. The Brittle index (BI), Young’s modulus and
poison’s ratio on brittle layers were range from 0.4 to 0.78, greater
than 25 GPa and <0.3 respectively for brittle layers. Based on failure
parameters, insitue stresses and mud weight three possible locations for
wellbore breakouts, fractures, has been identified where special
considerations are needed to select the mud weight in order to avoid the
problems i.e. sand production, wellbore instability. The strongest
depths for minimum wellbore stability have been identified that have
also high BI (0.6 to 0.69) and can be potential target for stimulation.
Based on results, it has been concluded that this Roseneath shale
interval of Moomba 191 well have many critical zones based on limits of
upper and lower safe mud weight window where extra care need to be
taken. The normal stress regime exhibited that fractures orientation
will be perpendicular to minimum horizontal stresses. |
