Kiran Raj, S.
Prabhakar and J. Rajesh Kumar |
Abstract: |
This Paper focused on the
Citronella oil based bio diesel which is important renewable
and alternative fuel in future. Citronella oil is used as a
input for biodiesel production via transesterification. Diesel
fuel is much higher use than any other gasoline fuels because
diesel engines have many adaptabile domestic uses like small
irrigation water pumbing systems, light weight four/two seated
auto cab and car engine small electricity generators etc.
Citronella biodiesel fuel properties are observed and tested
in the fuel testing laboratory with standard procedure. Then
an experimental set up is construct to study the performance
of a small Kirloskar Diesel in the internal combustion engine
by using different blends of Citronella Oil based biodiesel
under different Operation Conditions. We have to determine the
optimum performance of this citronella biodiesel. NOx emission
from the test engine can be measured by chemical luminescent
detector type NOx analyser. |

Y. L. Lee |
Abstract: |
In order to improve the efficiency of the
refrigeration cycle or the heat pump cycle, it is important to
improve the efficiency of a compressor. In this study, the
authors intended to develop a three-dimensional numerical
model that can predict the performance of a linear compressor.
For this purpose, CFD model which can simulate the entire
cycle was developed. The numerical analysis on the cooling
capacity of two linear compressors was successfully conducted
and the numerical results were in good agreement with the
experimental results. In future, if considering the detailed
valve behavior, the accuracy of the numerical analysis model
can be further improved. |

Abstract: |
This paper presents the
investigation of influence of matric suction on unconfined
compressive strength of clayey soils with different sand
contents. The matric suction within clay samples with cement
contents of 0, 20 and 40 percent was applied using the suction
chamber. The results show that the unconfined compressive
strength increased with increasing matric suction for the
matric suction range less than 50 kPa but decreased with
increasing matric suction for the suction range greater than
50 kPa. The results also show that the unconfined compressive
strength increases with increasing sand content for all values
of matric suction. Furthermore, the values of unconfined
compressive strength normalized by matric suction for the
samples with different sand contents trend to converse to each
other at high value of matric suction. |

Analysis of
hybrid slot antenna based on substrate permittivity |
Author (s): |
B.
Sadasivarao and B.T.P. Madhav |
Abstract: |
Most of the microstrip patch antennas are
constructed on thin substrates with low dielectric constant.
The demand of millimeter wave and monolithic fabrication
increased the interest of thick substrates with high
dielectric constant. The efficiency of the antenna will
decreases with increase in substrate permittivity but size of
the antenna also decreases. When substrate permittivity is
decreased, then performance can be improved. The thicker
substrates will increase the bandwidth but if it exceeds some
point then surface wave losses will be affected. Thinner
substrates will not give bandwidth enhancement but surface
wave losses can be decreased. There is tradeoff between
substrate material selection and the performance of the
antenna and the size. Without changing the substrate material,
the size reduction can be achieved by employing slots in the
model. The purpose of this paper is to provide a set of output
parameters of hybrid slot antenna with change in substrate
permittivity. The performance evaluation of hybrid slot
antenna is carried out by changing the dielectric constant of
the materials by maintaining the constant thickness of 1.6mm. |

Study of
impact of climate change on water availability in the gumti
hydropower plant, tripura, India using artificial neural network |
Author (s): |

Roy P. K. and Mazumdar A |
Abstract: |
Electricity is recognized as fundamental to
industrialization and improving the quality of life of the
people. Harnessing the immense untapped hydropower potential
in Tripura region opens avenues for growth and provides an
opportunity to improve the well-being of the people of the
region, while making substantial contribution to the national
economy. Gumti hydro power plant generates power to mitigate
the crisis of power in Tripura, India. The first unit of hydro
power plant (5MW) was commissioned in June 1976 and another
two units of 5 MW was commissioned simultaneously. But out of
15MW capacity at present only 8MW-9MW power is produced from
Gumti hydro power plant during rainy season. But during lean
season the production reduces to 0.5MW due to shortage of
water. Hence forecasting models are necessary to predict the
future available water based on past and current information.
Water prediction will tell us whether the coming years will be
good, bad or average. Accordingly contingency measures can be
planned well in advance. The present investigation tried to
analyze the impact of climate change on availability of water
in the Gumti Reservoir using Artificial Neural Network. In
this regard a neural network model is developed and
implemented for prediction of the volume of water in the
reservoir due to the change in meteorological variables which
is imminent for the future climate change scenarios as
predicted by the PRECIS climate models. As per the model
prediction there will be a deficit in the water availability
of the reservoir. The level of deficit will be 25.17% in A2
scenario under peak flow conditions and 20.52% in lean flow
condition for A1B scenario. |

Influence of
fly-ash as a filler in bituminous mixes |
Author (s): |
Debashish kar,
Mahabir Panda and Jyoti Prakash Giri |
Abstract: |
A bituminous paving
mixture is a mixture of
coarse aggregate, fine aggregate and bitumen mixed in suitable
proportion to result strong and durable mix to withstand
traffic load. In this paving mix, normally cement and stone
dust are used as filler material. A study has been carried out
in this study to explore the use of fly ash, a by-product of a
coal based thermal power plant in bituminous paving mixes. For
comparison, control mixes with cement and stone dust have also
been considered. Marshall test has been considered for the
purpose of mix design as well as evaluation of paving mixes.
Other performance tests such as indirect tensile strength and
retained stability have also been carried out. It is observed
that the mixes with fly ash as filler exhibit marginally
inferior properties compared to control mixes and satisfy
desired criteria specified by a much higher margin. Hence, it
has been recommended to utilise fly ash wherever available,
not only reducing the cost of execution, but also partly solve
the fly ash utilisation and disposal problems. |

A highly
constrained geometric problem: the inside-out-human-based
approach for the automotive
vehicles design |
Author (s): |
Luca
Piancastelli, Leonardo Frizziero and Giampiero Donnici |
Abstract: |
The traditional automotive design process that
starts from the sketches and the 2D drawings has been
superseded by the modern CAD modeling tools. The step through
the clay model and the following digitalization problems can
be superseded. It is now possible to construct the inside and
to define the ergonomic boundaries of the vehicle in an inside
out process. This approach greatly reduces the time to market
of the final product by including all the parts and the
components that comes from other projects or from outsourcing.
However a 1:1 (true scale) physical mock up of the vehicle is,
in most the cases, still necessary. In fact the evaluation of
the real aesthetics of the new project should be made in a
true 3D environment. The inside-out approach optimizes the
standardization, the outsourcing, the multi powertrains and
the unified "platform" concepts. |

Title: |
The
extensiveness of ICT application in the maintenance of
government office buildings in Malaysia |
Author (s): |

Abstract: |
Information and Communication
Technology (ICT) has benefited many economic industries. The
construction industry is also one of these industries that
have improved in terms of quality, preservation, and also
means of communication between parties of a building
life-cycle. This paper aims to identify the extensiveness of
ICT application in the maintenance of government office
buildings in Federal Territoryof Putrajaya, Malaysia.
Putrajaya has been selected as the focus of this study as it
is the central administration of Malaysia. Primary data were
obtained through interview sessions with the relevant parties
including officers from the Public Works Department (JKR),
planner from the Putrajaya master developer (Putrajaya Holding
(PJH)) and also an officer from a construction company
focusing on software for maintenance (Stagno Tech Sdn. Bhd.).
It was found out that ICT is used extensively in terms of
maintenance of the government office buildings and has
provided a better means of communication for building
occupants and building operators to communicate between each
other. It was found out that the building occupants still
prefer the old method of communication - that is by calling
the maintenance call-centre. Nevertheless, the system used by
Public Work Department for the maintenance of the said
buildings i.e. CWORKS have proven effective as it stores,
processes and transfers data and information from one party to
another effectively. Allocation of resource, time, and
responds to users who lodged the reports or complaints can be
done much faster with the interconnectivity of the different
parties through the system. Although ICT has proven effective
so far, much more can be done to improve the building
maintenance scenario. Perception of users towards ICT can be
further improved by portraying more benefits of ICT in aspects
of time, cost, quality and also comfort. |

Comparison of
stehfest’s and iseger’s algorithms for laplacian inversion in
pressure well tests |
Author (s): |
Freddy Humberto Escobar, Fabián
Andres Leguízamo and Jose Humberto Cantillo |
Abstract: |
This paper presents the comparison of two
algorithms used for the numerical inversion of the Laplace
transform. The comparison was applied to two well-known
oil-industry reservoir models in the Laplacian domain, for
which the inversion is made and the results are plotted to
establish comparison. Not only accuracy but also computing
effort was studied. Although, the Iseger’s algorithm is
computationally much heavier it handles more efficiently
functions with discontinuities or functions having sharp
changes. It was also observed in
well tests that fulfilling the conditions relating time with
the number of sample points leads to more stable inversions.
It was also found that the greater the number of points to be
inverted, the more accurate the solution. Moreover, the
oversampling parameter nrp provides more stable
solutions when it takes the value of three contrary to eight
as initially proposed by Iseger. |

Probabilistic
approach to reliability evaluation of lifting wire ropes |
Author (s): |
Mouradi Houda,
El barkany Abdellah and El biyaali Ahmed |
Abstract: |
Wire ropes are used for different applications
in many industrial domains, for instance, lifting system.
Depending on the conditions of use,
wire ropes are being degraded with direct
consequences are significant changes of geometric and
mechanical characteristics of its components.
This results in a reduction in the resistance
capacity of the wire rope with time, which could bring
failure.
Two parameters are susceptible to depict this
degradation: a continuous variable which is damage and a
statistical variable which is reliability. Our work consists
of studying the impact of the breaking of the wires which
constitute the wire ropes on its duration. For that we will
establish a model that will allow us to connect the two
parameters (Damage and reliability) and we will thus broaden
this link to the case of compound systems.
We are equally proposing to develop a new model which permits
providing the reliability of a wire rope in multiple levels of
damage of its components. The method adopted is a multi-scale
approach with a total decoupling between the scale of the wire
and the wire rope. |

Abstract: |
Visually impaired individuals have relied on a
variety of techniques to actively participate in society.
There are many available technologies both wearable and
non-wearable to assist them. These either provide them
assistance in walking, or some help them to recognize things
by audio or touch feedback. Our approach is to provide a
low-cost wearable assistive system which can not only help
blinds to navigate freely, but also tells them the time. The
system will also enable a distant mobile user to monitor body
vitals of the blind person and in case of any emergency the
blind can call him with just one press of a button. So
overall, the system provides not only aids to the blind, but
also to his/her family members. |

Abstract: |
Panorama
stitching or image stitching is gaining prominence in today’s
world due to its applications in wide context aware imaging.
The project aims on three different image stitching techniques
and comparing their efficiencies and computational time. After
the image is acquired, if the image parameters are unknown,
feature detection and extraction is carried out without
undistortion and cylindrical warping. In this case, the SIFT
features are calculated from the acquired images and the
images are translated based on the obtained homography. Then
images are blended using alpha or weighted blending. If the
image parameters, such as focal length and intrinsic
parameters are known after image acquisition, the image first
undergoes undistortion and warping. After that, two approaches
are followed to compare efficiencies between the methods. The
first approach involves the direct method in which the
translation between the images is calculated with the need for
features to reduce the calculated time manifolds and aid in
faster translation approximation. And also feathering is
performed to blend the images seamlessly and obtain the
stitched image. In the second approach, the feature based
method is used wherein the SIFT features are calculated for
the image sets. Following this, the features are used to
calculate the homography between the two images and determine
the translation. Then, the images are stitched using a
different blending technique called pyramid blending. This
technique proves slightly more efficient than the previous
technique due to computation of Laplacian and Gaussian
pyramids of the images. |

Abstract: |
The study was designed to determine the optimal
mixing ratio of cattle paunch manure (PM) and cow dung (CD) in
biogas production under tropical condition.
The mixing ratio used were 100: 0,
75: 25, 50: 50, 25:75 and 0:100 for paunch manure and
cow dung, respectively. The fermentation was carried out in
five 30 litres digesters locally fabricated for 30 days.
The biogas
yields obtained were in the order of 50% PM + 50% CD > 75% PM
+ 25% CD > 100% PM + 0% CD > 25% PM + 75% CD > 0% PM + 100%
CD. Thus, the optimum mixture ratio for paunch manure and cow
dung obtained from this study is 50% PM + 50% CD mixture ratio
with cumulative yield biogas of 76.42L/Total Mass of Slurry
(TMS) within the period of study. The experimental data of all
the treatments were fitted to Gompertz relation, which showed
adequate fit. |

Enhanced
wavelet packet based un compressed video watermarking algorithm
with frame selection and HVS criteria |
Author (s): |
T. Jayamalar
and V. Radha |
Abstract: |
Digital video is a group of moving visual
images, text and sounds. The popularity of using digital video
in Internet leads to illicit copying and dispersal of content.
Inorder to avoid this, video watermarking technique are used
as a preventive measure for illegal copying of copyrighted
material. In this paper,
watermarking algorithm for identification of optimal frames
and embedding of nested watermark using static block selection
is proposed. The nested watermark is embedded in the
uncompressed video data and is extracted without the use of
original video sequences. These algorithms preserve the video
quality and provide more security. The performance of the
algorithm is analyzed using Peak Signal to Noise Ratio,
Normalized Correlation and Mean structure similarity index
with respect to various attacks. Experimental evaluation
demonstrate that the proposed algorithm perform satisfactorily
compared to traditional algorithms in terms of payload,
transparency and it is also robust against various attacks. |

Abstract: |
A mechanical
device to control kart’s tire pressure was developed. This
valve must blow air when temperature’s tire and pressure rise
with a not acceptable shape deformation and a corresponding
modification of the vehicles trim. With the new solution,
drivers can drive faster and more safely. Two design methods
have been utilized: QFD and TRIZ. The first one, Quality
Function Deployment, offers a clarification tool for
organizing the information flow in a structured way, and TRIZ,
Theory of Inventing Problem Solving, is an efficient tool in
the discovering the solution principles. With TRIZ’s Table,
technical and physical contradiction are put in evidence and
eliminated to improve the robustness of the device. The two
methods interact one another and offer the best path for the
development of a new design. |

Green homes
development: factors affecting housing developers’ readiness |
Author (s): |
Fazdliel Aswad
Ibrahim, Mohd Wira Mohd Shafiei, Radzi Ismail and Ilias Said |
Abstract: |
Housing can be inferred as an
industry with activities that provide buildings and structures
with the aim to fulfill the human needs for shelter,
protection from any dangers and as a rest place after daily
activities. The demand for housing keeps increasing in
consistence with the rising number of global population as
people seek for betterment of life in the modern civilization.
The Malaysian housing industry experiences similar
circumstances. However, Malaysian government has stressed that
the provision of housing should be developed in a sustainable
manner. In order to encourage sustainable practice in the
housing industry, the government has urged the housing
developers to develop green homes by introducing incentives in
relation to green technology development as well as become a
leader in green building design. Nevertheless, most of the
housing developers are still reluctant to develop green homes.
This study aims to identify factors that influence readiness
of housing developers to develop green homes. A
questionnaire-based survey was carried out within 395 housing
developer firms and 249 questionnaires were duly returned.
Statistical analyses such as descriptive analysis, exploratory
factor analysis and multiple regression analysis were utilized
to analyze the data. This study found that there are three
significant factors influencing Malaysian housing developers'
readiness to develop green homes that comprise of government
supports, external expertise supports and housing market
readiness. This implies that government’s role, the
availability of local green technology expertise and marketing
research on housing market will facilitate the housing
developers to develop green homes in Malaysia. |

Particle
swarm optimization technique for rule base optimization of FLC
for low speed acc vehicle |

A. Immanuel
Selvakumar |
Abstract: |
Adaptive Cruise Control is used in vehicles for
giving support to the drivers and to circumvent rear end
collision. Due to the presence of nonlinearity in the vehicle
(system), it is difficult to design an exact mathematical
model of the system. Heuristic based fuzzy logic controller
with optimized rule base, which does not require accurate
mathematical modelling is proposed here which uses the
knowledge of the designer for developing the rule base. The
performance metrics in terms of better control and response
time of the controller depends upon how well the rule base is
formulated. More the number of rules in the rule base, higher
the search time and increase in the total response time of the
system but better will be the control. On the other hand, if
the rules are less, then the search time will reduce which in
turn decreases the total time of response of the system but
control will be poor. In order to obtain an optimized control,
the rule base is optimized using Particle Swarm Optimization
technique. The result had shown a better performance. |
