Abstract:
Laptops in 21
st century are an integral part of every professional in vivid fields. Off late there has been
emergence of several ergonomic injuries such as repetitive strain injuries (RSIs) due to extensive usage of
laptops, which can be closely linked with applied force and postures. This study investigated the effect of
various angles of keyboard on the applied force and motor action plus response time while performing five
distinct tasks. On the basis of literature two different laptops were selected for performing different tasks. For
each case the three levels of platform angle were considered as 0°, 5°, and 10°. Male subjects were selected to
perform five distinct tasks for each platform angle for both laptops. The force applied (in milli-volts) and the
motor action plus response time (milli-seconds) were recorded using an oscilloscope. The data collected were
analyzed through ANOVA using MINITAB software. The abduction angle with the least mean response time
and applied force were considered as the best from ergonomics viewpoint. The ANOVA results showed that the
angle of abduction for both laptops (small and large) do have significant effect on applied force but not on motor
action plus response time. The analysis of results indicate that 10° angle of abduction in case of small laptops
should be applied to minimize musculoskeletal disorder and repetitive strain injuries.
Research relevance: This work suggests that those responsible for the function and operation of laptops would
have to redesign the system to reduce injuries, as far as musculoskeletal disorder, repetitive strain injuries and
other related problems are concerned. The present work can be quite useful for the system designers of
tomorrow.

Abstract:
Indonesia has renewable energy source very large, as biomass. Installed capacity power plants of Indonesia
now 53,585 MW, where the potential energy biomass is the largest of renewable sources of energy that owned
by Indonesia. The machine of gasification is designed to produce combustible gas (CO, H
2, CH
4). These
combustible gas are produced to replace fossil fuel as engine fuel to generate electricity. However, the
properties and characteristics of these combustible gas should meet the characteristic of the engine as every
engine has its own specific characteristic. In this research, Biomass Power Generation (BPG) which work more
properly with CO was used. High level of tar contained in produced combustible gas contaminates the engine
filter rapidly. Therefore, the machine cannot be operated at a longer time. The objective of this research was to
study the potential application of downdraft gasification machine with high content of CO and low production
of tar. Downdraft gasification machine which designed in this research had installed capacity as much as 50 kW
with reactor diameter and height were 900 mm and 1000 mm, respectively. The testing result showed that power
generated from this machine was 40 kW, efficiency 80 % and can be operated for 6 hours. The optimum
combustible gas produced by this machine occurred at CO, H
2 and CH
4 content were 21.75 %, 13.12 % and 1.12
%, respectively. Besides of using active carbon, tar removal was carried out using dust trap system (wet
scrubber). The potential reduction of value of greenhouse gases emission is about 37 until 67 %. Based on an
analysis calculation of financial , a test performance of gasification, and analysis of environmental impact, the
use of system gasification can be used on a system a power plant in the isolated area from national electricity
company in Indonesia.

Abstract:
Artificial roughness is an efficient way for increasing the heat transfer rate in solar air heater with the
corresponding improvement in its thermal performance. A viscous sub-layer is responsible for the low heat
transfer coefficient between absorber plate and flowing air. Repeated ribs in form of artificial roughness are an
effective way to increase the heat transfer rate and improving the performance of solar air heater. Artificial
roughness of the absorber plate is much economical and effective way to improve the thermal performance of
solar air heater. Several investigators have done various investigations to improve heat transfer coefficient with
little penalty of friction factor. They have also developed different correlation for heat transfer coefficient and
friction factor. The correlations developed for heat transfer and friction factor by various investigators have been
reviewed and presented.

- A New Approximation of Water Saturation Estimation Based on
Vertical Seismic Profiling Data

[Abstract]
[PDF]
[Cite]
Abstract:
Water saturation is the ratio between the volumes of fluid in the rock pores. Water saturation is one of the
important reservoir parameters to be known in the exploration or exploitation of oil and gas. I have developed a
new technique to estimate the distribution of water saturation values based on the seismic wave attenuation
analysis, frequency and porosity from the equation of Biot-Turgut-Yamamoto-Sismanto. It is applied to the real
data using the vertical seismic profiling (VSP) data in Pasir Cantang well, West Java for some layers.
The obtained values of water saturation have not been calibrated to the known value of the well. This step needs
to be done, so that the results that have been corrected can be performed to estimate the area around the well
Pasir Cantang guided by seismic section. Regardless of the calibration factor, the method of the water saturation
estimation on VSP data can technically be well done but still needs necessary calibration for the accuracy.

Abstract:
This work focuses on the study of the chemical reactivity of an advanced oxidation process (AOP), called the
plasma technique, in order to prevent industrial effluent from pollution and better cope to several damage of
environment. The oxidizing and acidifying properties of an electric discharge of the gliding arc plasma and its
application to a target which is a real effluent (wastewater from Brasseries du Cameroun -Bafoussam plant)
fascinated this study. Samples were collected from the central collecting point (CCP) of the effluent. The
collected effluent samples were analyzed by volumetric and instrumental methods, and then exposed to the
gliding discharge during specific time periods of 3-60 min to exhibit the desired decontamination effects. At the
end of 60 min of exposure time to the discharge, 52.22% and 50.19% obtained respectively to abatement of
turbidity and rate of fall in absorbance. This reduction can be explained by the fact that the coloured compounds
were degraded and this degradation gave rise to the transparent appearance observed. After stopping the
discharge process, the abatement percentage of BOD
5, COD and TOC, were obtained at the same time (60min)
with values of 52.05%, 68.63% and 69.37% respectively. These results reflect the considerable reduction of the
pollution load of the wastewaters collected from CCP of the brewery. These results showed that the
effectiveness of the gliding arc plasma depends not only on the physico-chemical parameters of the target, but
also on the exposure time and concluded that the non-thermal plasma process alone provides good reduction of
organic pollutants in wastewater. Moreover, the phenomenon of post- discharge, even though not studied in
details demonstrated that, after switching the discharge, the evolution of parameters such as pH, electrical
conductivity and TDS increase.

Abstract:
Pyrus elaeagnifolia Pallas. ssp. elaeagnifolia is a medicinal plant used in traditional medicine for the treatment
of various diseases in Turkey. The leaves of Pyrus elaeagnifolia ssp. elaeagnifolia are a rich source of arbutin,
which is a naturally occurring derivative of hydroquinone. It is found in various plant species belonging to
diverse families, such as Lamiaceae, Ericaceae, Saxifragaceae and Rosaceae. It inhibits tyrosinase and has
been employed as a cosmetic skin whitening agent. In this study, Response Surface Methodology (RSM) using a
Box Behnken Design (BBD) was employed to optimize the condition for extraction of arbutin from the leaves of
Pyrus elaeagnifolia ssp. elaeagnifolia. Three influencing factors; methanol concentration, period of ultrasoundassisted
extraction and extraction temperature were investigated in the ultrasonic aqueous extraction. The
Response Surface Methodology was applied to optimize the extraction process focused on arbutin content with
respect to the above influencing factors. The best combination of each significant factor was determined by
RSM design and optimum pretreatment conditions for maximum arbutin content were established to be
methanol concentration of 48.54 %, extraction time of 39.32 min. And extraction temperature of 43.71 0C.
Under these conditions 5.37 % of arbutin content was observed experimentally, similar to the theoretical
prediction of 5.30 %.

Abstract:
Automation or automatic control is the use of various control systems for operating equipment such as
machinery, processes in factories, boilers and heat-treating ovens, switching in telephone networks, steering and
stabilization of ships, aircraft and other applications with minimal or reduced human intervention. Some
processes have been completely automated. The motor speed is controlled via the driver as an open loop control.
To make a more precise closed loop control of motor speed we will use a tachometer to measure the speed and
feed it back to the PLC, which compares to the desired value and take a control action, then the signal is
transferred to the motor – via driver – to increase / decrease the speed. We will measure the speed of the motor
using an incremental rotary encoder by adjusting parameters (PLC, driver) and also we need to reduce the
overall cost of the system. Our control system will be held using the available Siemens PLC. In addition, we will
monitor motor parameters via SCADA system.

Abstract:
"Alert System for High Speed Vehicles to Avoid Wildlife Accidents" is an alert system used to safeguard our
wildlife. We often hear of various accidents of wild animals like elephant, nilgai etc., who are trying to cross the
railway track. So, an intelligent electronics system is necessary which can be affixed to avoid the possibilities of
accidents. Regarding this, in our project we are using a Passive Infrared Sensor (PIR sensor) which is an
electronic sensor that measures infrared (IR) light radiating from objects in its field of view and switches ON
any electrical/electronic device to which it is connected to. The key component of the sensor module is the pyroelectric
element. All objects with a temperature above absolute zero emit heat energy in the form of radiation.
Usually this radiation is invisible to the human eye because it is radiated at infrared wavelengths, but it is
detected by this PIR sensor. This sensor does not radiate any energy for detection purposes and thus, it has no
harmful effects on living beings. In our project the PIR sensor is used as a part of a burglar alarm and the
electronic in the PIR typically control a small relay. This relay completes the circuit across a pair of electrical
contacts connected to a detection input zone of the burglar alarm control panel. The system is usually designed
such that if no living creature is being detected, the relay contact is closed- a "normally closed‟ (NC) relay. If
energy emitted from any nearby creature is detected, the relay opens, triggering the alarm, a signal will be
directly sent to the driver‟s chamber and it will create a message in the LED screen of his chamber also an alarm
will be heard which we have implemented using an ultrasonic sensor hc-sr04.

- Analysis of Stress and Deflection of Cantilever Beam and its
Validation Using ANSYS
Ashis Kumar Samal, T. Eswara Rao
[Abstract]
[PDF]
[Cite]
Abstract:
This study investigates the deflection and stress distribution in a long, slender cantilever beam of uniform
rectangular cross section made of linear elastic material properties that are homogeneous and isotropic. The
deflection of a cantilever beam is essentially a three dimensional problem. An elastic stretching in one direction
is accompanied by a compression in perpendicular directions. The beam is modeled under the action of three
different loading conditions: vertical concentrated
load applied at the free end, uniformly distributed load and uniformly varying load which runs over the whole
span. The weight of the beam is assumed to be negligible. It is also assumed that the beam is inextensible and so
the strains are also negligible. Considering this assumptions at first using the Bernoulli-Euler's bendingmoment
curvature relationship, the approximate solutions of the cantilever beam was obtained from the general
set of equations. Then assuming a particular set of dimensions, the deflection and stress values of the beam are
calculated analytically. Finite element analysis of the beam was done considering various types of elements
under different loading conditions in ANSYS 14.5. The various numerical results were generated at different
nodal points by taking the origin of the Cartesian coordinate system at the fixed end of the beam. The nodal
solutions were analyzed and compared. On comparing the computational and analytical solutions it was found
that for stresses the 8 node brick element gives the most consistent results and the variation with the analytical
results is minimum.

- A Novel Approaches For Chromatic Squander Less Visceral
Coding Techniques Using Maneuver Stabilization

[Abstract]
[PDF]
[Cite]
Abstract:
Recent advances in video capturing and display technologies, along with the exponentially increasing demand of
video services, challenge the video coding research community to design new algorithms able to significantly
improve the compression performance of the current H.264/AVC standard. This target is currently gaining
evidence with the standardization activities in the High Efficiency Video Coding (HEVC) project. The distortion
models used in HEVC are mean squared error (MSE) and sum of absolute difference (SAD). However, they are
widely criticized for not correlating well with perceptual image quality. The structural similarity (SSIM) index
has been found to be a good indicator of perceived image quality. Meanwhile, it is computationally simple
compared with other state-of-the-art perceptual quality measures and has a number of desirable mathematical
properties for optimization tasks. We propose a perceptual video coding method to improve upon the current
HEVC based on an SSIM-inspired divisive normalization scheme as an attempt to transform the DCT domain
frame prediction residuals to a perceptually uniform space before encoding.
Based on the residual divisive normalization process, we define a distortion model for mode selection and show
that such a divisive normalization strategy largely simplifies the subsequent perceptual rate-distortion
optimization procedure. We further adjust the divisive normalization factors based on local content of the video
frame. Experiments show that the scheme can achieve significant gain in terms of rate-SSIM performance and
better visual quality when compared with HEVC.

Abstract:
The consumption of energy in the buildings is increasing as the development is taking at a very fast rate. No evidence is now
required to prove that the present climate changes are directly linked to the human activities and also the concerns regarding
exploitation of the fossil fuel have reached a level where the negative effect are having impact on the life of a common man.
Passive Architecture involves blending conventional architectural principles with solar & wind energy and the inherent
properties of building materials to ensure that the interiors remain warm in winter and cool in summer, thus creating a yearround
comfortable environment. Various solar passive techniques have been studied in detail so that the undesirable impact
in hot and dry climate could be mitigated. It is concluded that with the application of these techniques the building could be
made comfortable with comparatively less use of energy.

Abstract:
In this paper we proposed a face detection method based on feature selection and feature optimization. Now in
current research trend of biometric security used the process of feature optimization for better improvement of
face detection technique. Basically our face consists of three types of feature such as skin color, texture and
shape and size of face. The most important feature of face is skin color and texture of face. In this detection
technique used texture feature of face image. For the texture extraction of image face used partial feature
extraction function, these function is most promising shape feature analysis. For the selection of feature and
optimization of feature used multi-objective TLBO. TLBO algorithm is population based searching technique
and defines two constraints function for the process of selection and optimization. The proposed algorithm of
face detection based on feature selection and feature optimization process. Initially used face image data base
and passes through partial feature extractor function and these transform function gives a texture feature of face
image. For the evaluation of performance our proposed algorithm implemented in MATLAB 7.8.0 software and
face image used provided by Google face image database. For numerical analysis of result used hit and miss
ratio. Our empirical evaluation of result shows better prediction result in compression of PIFR method of face
detection.

Abstract:
The aim this research paper was to evaluate the phytochemicals and free radical scavenging activities of
ethanolic extract of plants like Toddalia asiatica, Polygala arillata, Debregeasia longifolia. The main secondary
metabolites such as Alkaloids, Phenols, Flavnoids, Tannins and Saponin have been evaluated among the plants
analysed. The antioxidant potential of ethenolic extract of T. asiatica, P. arillata and D. longifolia leaf and stem
using tests involving inhibition of lipid peroxidation, hydroxyl radicals, Superoxide anions and 1, 1-diphenyl 2-
picrl – hydrazyl free radical (DDPH). The present study revealed that ethanolic extract of Leaf and stem of T.
asiatica, P. arillata and D. longifolia are the potential sources of natural antioxidants that could be of greater
importance in folkloric medicines.

Abstract:
With the traditional fund management and vote bank analysis, it was difficult to manage and analyze the details
of fund collection and vote bank where all the records and relevant details were maintained at manual level,
which is always a troublesome process. To overcome these problems, an online web application is being
developed which provide the means of maintaining the funds gathered, Analyzing vote bank generated, Analysis
of area wise grievances and providing data security using encryption algorithms like Advanced Encryption
standard enabling two step verification mechanisms such as legitimate user authentication and secured access to
data. Also various reports will be generated depicting graphical assessment of information gathered.
