Abstract: |
Chemical pulping of durian shell fiber is a comparatively new approach
in the field of pulping, and the paper industry as a whole. Pressures of
rising wood resource consumption have resulted in increased attention on
the use of non-wood raw materials in the papermaking industry. This
situation is due to trees being exploited in high numbers for the
purpose of paper manufacturing. Thus, some alternative solutions have
been developed to remedy this. Natural resources wastes like kenaf,
bamboo and sugarcane bagasse are used as the raw material to produce
these varied grades of paper. Additionally, cellulose fiber possesses a
natural tendency to absorb moist and water vapor from the surrounding,
producing weak mechanical properties and limiting paper’s use.
Therefore, in this study, lignin acts as a natural plasticizer in plant
cell wall has been optimized to overcome the hygroscopic issue. An
optimal amount of lignin will generate maximum hydrophobic effect to
prepare for the production of water resistant paper. The process is
optimized under the influence of three operational variables; 1) % of
NaOH, 2) cooking temperature, and 3) period of cooking. To analyze the
response, two level factorial design method by Design Expert v.6.0.8
software has been used. The results show that the highest water contact
angle reading of 70.33° has been achieved at the condition of 17 %
alkalinity, 140 °C of cooking temperature and 120 min of cooking period.
At the same process condition, the highest amount of lignin (57.67 %)
has also been obtained which showing the significant interaction between
lignin and the hydrophobic effect. From the analysis of variance
(ANOVA), all parameters have significantly affected the reading of water
contact angle. The P-value of the experiment model is less than 0.0001
and the coefficient of determination value (R2) is 1.000. This
conclusively suggested that the model is significant and influences on
the precision and process-ability of the production. |

Abbas H. Ali |
Abstract: |
Behavioral of Glass Fiber Reinforced Pipes includes several important
points which are as worthy to study as the main aim of present study
which is to find stability represented by pipes deflection. To find
pipes deflection, it was decided to take AL-Hindi District Sewage
Network as a case study. The diameter of Grp Pipe was selected of 1.4m
that to be made in KSA. Two methods have been chosen to check stability and
behavior of this type of pipes under real field condition.
The first method was done by using AWWA formula, while the second method
was performed by using finite element Analysis which is done by plaxis
3D software. It was found that the maximum predicted value of pipe
deflection reached the value of (2.9388%) at maximum depth of (10) m but
when applying finite element method the above maximum mentioned
deflection was reduced to (0.6744 %) at the same maximum depth of (10)
m. The significant difference between the two values which have resulted
by using the two different methods can be attributed to the technique
used in these two methods and the personification of field condition in
each method .Both results consider safe value according to specification
limit 5% with difference of safety factor degree. Field test must be
done to find measured deflection which is considered conclusive evidence
and degree of pipe line stability. |

Author (s): |
M. Sangeetha and S. Prakash |
Abstract: |
The
objective of this work is to compare the loss of material in the
drill bit after drilling the metal matrix composites coated with carbon
nano tubes with uncoated metal composites. In this work, two different
specimen are fabricated using stir casting process. The fabricated
specimen includes coated silicon carbide particles reinforced in LM 25
alloy and uncoated ceramics reinforced in LM 25 alloy. The carbide drill
bit is analyzed after drilling metal matrix composites with 10% silicon
carbide particles in LM 25 and hybrid metal matrix composites with 10%
of silicon carbide particle and 1.5% of Multi Wall Carbon Nano Tubes (MWCNT)
in LM 25 alloy. Morphology of the drill bit is recorded using Scanning
Electron Microscope (SEM). The metal matrix composites (LM 25/SiCp) and
hybrid metal matrix composites (LM 25/MWCNT coated SiCp) are prepared
using semi-solid stir casting method. The fabricated specimen is
subjected to machining. After machining the flank, chisel edge and flute
of the tool are analyzed using SEM. The wear and the built up edges are
studied using morphology in the flank, chisel edge and the flute. From
the morphological study it is proved that the depth of wear in the
carbide tool used to machine the uncoated metal matrix composite is more
compared to the depth of wear used to machine the coated metal matrix
composites. It is also proved that distribution of coated ceramics;
silicon carbide particles on the LM 25 matrix are uniform. |

using ZigBee and Zynq FPGAs |
Author (s): |
M. Vishwanath, Himani Goyal and
Habibulla Khan |
Abstract: |
The
last decade has witnessed immense increase of wireless networks for
different applications in mobile communication, internet, and industrial
automation. The next generation wireless nodes will be used in real time
applications such as auto navigation, cloud computing and ad-hoc data
networks etc. These applications need precise time synchronization to
function properly. In this paper, the time synchronization between two
wireless nodes is achieved using novel technique. The main principle is
to periodically synchronize clocks running in two different nodes
through wireless communication protocols. Each node consists of one
ZigBee module working at 2.4 GHz ISM (Industrial, Scientific and
Medical) band radio and Zynq Configurable System on Chip (C-SOC)
platform. Based on the ZigBee communication the Field Programmable Gate
Array (FPGA) running real time clock with resolution of 10 nano seconds
is synchronized through software. The modules developed in this
experiment are FPGA real time counter, External Trigger interface module
and UART communication. To validate the developed method another Spartan
3E FPGA generated trigger pulse is used. The time synchronization error
is among the two wireless nodes is analyzed and plotted using Matlab.
The results demonstrated reduction of time synchronization error up to
10 micro seconds. The work is aimed to be extended towards realizing
other techniques for further improvement in the time synchronization. |

Abstract: |
The
attenuation values polycarbonate material was evaluated using the XCom
database. The results were compared with the attenuation values of the
human thyroid published by the International Commission on Radiation
Units and Measurements - ICRU no. 44. The adult thyroid was designed
from scratch as a 3D thyroid model using the 3Ds Max software. The model
was then 3D printed with a Pursa i3 printer using the polycarbonate
material. The Scintigraphy images were obtained after injection of Tc-99
inside the thyroid phantom. The results show that the polycarbonate
material can be used as a tissue-equivalent substitute of human thyroid.
The quality of the images in nuclear medicine was evaluated, where the
images are similar to the images of a healthy human thyroid. The 3D
printing technology shortens the time of phantom fabrication and it
shows good results to mimic the real geometry of the human thyroid. |

Cooling system optimization for light
diesel helicopters |
Author (s): |
Luca Piancastelli, Michele Gardella and
Stefano Cassani |
Abstract: |
CRDID
(Common Rail Diesel Engine) main advantage is the reduced fuel
consumption, the safety and the flight readiness. In fact, diesel fuel
is available everywhere and flights to airports just for refueling can
be avoided. However, diesel engines are generally heavier than
turbo shaft and require cooling. This necessity is particularly important
during near stationary operations of the helicopter. If fans are used
for the cooling system, the available power is reduced with an increased
penalty weight for the installation. For this reason the ejector exhaust
system can be successfully used in CRDID powered helicopters. A
feasibility study for the installation of a CRDID (Common Rail Diesel
Engine) on a common light helicopter (AB 206) is introduced. The total
mass available for the CRDID is evaluated starting from fuel consumption
and helicopter data. A derivative of an automotive engine can be used
for the turbo shaft to CRDID powered plant conversion. The result is that
the installation is indeed possible and the payload can be slightly
increased in the diesel powered helicopter due to more power available. |

Author (s): |
J. K. R. Sastry, T. Naga Sai Tejasvi and J.
Aparna |
Abstract: |
RS485
based networking is quite often used for establishing a distributed
embedded system. The communication among the embedded systems that are
connected in a network is established through a serial communication
protocol. The embedded systems are identified with station numbers at
the time when the embedded system gets connected to the network. Most of
the communication is initiated through the master. Applications that are
implemented on a distributed embedded network needs that the messages
flow in a chronological sequence which can undergo a change from time
based on the environmental conditions prevailing when the system is in
running state. The criticality conditions as such keep changing from
time to time. The way the messages flows across the network changes
dynamically. In this paper, a dynamic scheduling algorithm has been
presented that effects the communication as per the environmental
conditions prevailing at any point in time. |

Author (s): |
M. Martinaa, V. Vaithiyanadhan and A.
Raghunadhan |
Abstract: |
In
wireless sensor network, detecting the node/link failure is a great
challenge .Failed nodes must be identified and renovated as earlier by
system controller to reduce the damage. Various fault detection
mechanisms have been suggested, these work cooperatively within a
particular region. Extending this concept to multiple regions will
decrease the efficiency in terms of time. In our proposed method in
Section 1 Superior Node Selection Mechanism (SNSM), we suggest an
approach for selection of superior nodes within a region. This superior
node is cooperatively connected to other nodes within the region and in
turn with other superior nodes belonging to other region in Section 2.
Given that, Superior nodes are scattered across multiple regions, each
superior node is connected via the SNL (Superior Node Linking)
Algorithm. |

Swaminathan Pichai Iyer |
Abstract: |
Speech communication is gaining lots of importance today made in common
technology especially in mobile technology. These technologies have
paved the way for users to access Internet using mobile devices,
particularly mobile phones. As the volume of multimedia data being
stored, accessed or shared over Internet is skyrocketing, there is a
significant demand for a high level of security to multimedia. In this
paper, a methodology for audio encryption is proposed. The method uses
Two-Key Dependent Permutation algorithm for scrambling the contents of
short length uncompressed audio. A high degree of unintelligibility of
the encrypted signal is achieved by providing two levels of security to
audio contents. The results obtained appear to be satisfactory. |

Local Area Networks |
Author (s): |
Macha Sarada and Avula Damodaram |
Abstract: |
This
manuscript explores a novel channel scheduling algorithm for varying
size windows transmission in 802.11 based Wireless Local Area Networks.
The objective of the proposal is to achieve maximum throughput and
minimal transmission loss and fair channel usage. The critical factors
considered to schedule a channel are optimal bandwidth and idle channel
availability. The proposed scheduling strategy is a hierarchical
approach of three levels. The optimal idle channel allocation, optimal
multiple idle channels allocation and optimal multiple channels with
considerable transmission intervals allocation are the objectives of the
respective levels of the scheduling hierarchy of the proposed algorithm.
The introduction of the WLAN and channel scheduling, associated
literature, detailed exploration of the proposed channel scheduling
strategy and performance analysis by simulation study were presented in
this article. The experimental study is evincing the scalability and
robustness of the proposal in the context of maximizing throughput and
minimizing the transmission loss. The performance analysis is done by
comparing the proposed model with contemporary scheduling strategies
found in recent literature. |

in distribution system with non-linear and linear loads using shunt APF |
Author (s): |
S. V. D. Anil Kumar and K. Ramesh Reddy |
Abstract: |
The
shunt active power filter has proved to be a useful device to eliminate
harmonic currents and to compensate reactive power for linear/nonlinear
loads. This paper presents harmonic identification and compensation for
harmonics using shunt active filter. With load consisting of linear and
non-linear loads, harmonics are induced in source components and affect
the other sensitive loads connected at point of common coupling.
Harmonics in source components insists for mitigation. Shunt active
power filter is a custom power device used to compensate harmonics in
power system source components. The work concentrates on identification
of harmonics when non-linear loads are placed at different nodes of
power system and their mitigation using shunt APF. Total Harmonic Power
method/Active Compensation method is used for identification of
harmonics. This paper proposes a new constant hysteresis current
controlled objective for shunt active power filter which maintains a
fixed switching frequency. In this control technique, the hysteresis
bandwidth need not be specified in entire control objective. The
operating principle of the proposed technique is proposed in this paper
and implemented. Proposed work is simulated using MATLAB/SIMULINK and
results are presented. |

Utilization of rice husk ash and ceramic
wastes in manufacturing of developed cement bricks |
Author (s): |
Azza I. Hafez, Maaly M. A. Khedr, Mona S.
Mohammed, Randa M. Osman and Rania M. Sabry |
Abstract: |
Huge
quantity of rice husk ash (RHA) and broken ceramics in Egypt are
produced as wastes and become of great threat to the environment,
causing damage to the land and the surrounding areas in which it is
dumped. In addition, production of cement is responsible for about 7% of
all CO2 generated in the world. For that, the aim of the present
research is to produce modified cement bricks by replacing cement
partially by RHA and broken ceramic wastes, to bring a substantial
reduction for CO2 emitted every year in the atmosphere, and to reuse
agricultural and industrial solid wastes. Therefore two sets of
experiments were investigated by replacing part of Ordinary Portland
Cement (OPC) with: 1) RHA and 2) mixture of RHA and ceramic wastes, to
produce modified cement bricks, at different curing time, namely7, 14
and 28 days. Characterizations of raw materials used for the target
preparation were carried out covering: free silica and organic matters,
XRD, TGA, and DTA. Thecold and boiling water absorption, compressive
strength, apparent porosity and bulk density for the prepared modified
concrete samples are determined. The experimental results proved that
the , modified cement brick contains 5% RHA and 3% ceramic powder as
cement replacement shows higher bulk density and compressive strength
compared to other brick samples. The bulk density and the compressive
strength were 2.33gm/cm3and 295 kg/cm2respectively, which are higher
than the allowable standard limits. In addition, preliminary production
cost was estimated. |

be used for the Philippine’s Manila Rail Transit (MRT) system. The group
would focus on two major tasks and that is for the interface of the RFID
reader to the PC and creating simulation that has a database that would
store, sort and retrieve data according to the needs of the system. The
input module for the simulation system is done in two methods first is
coming from the user input and the other one is with the use of RFID
tags to be read and checked by the reader before sending it to the
database system for recording and classification of data. The system has
also been made in accordance to the current situation of the MRT. With
the use different formulas and equations created by the group, would
then determine the train’s scheduling depending on the number of RFID
tags per station. This would also determine the number of passengers
that would enter the train station, and could possibly reduce people
congestion inside the train. This paper has been able to produce an
algorithm to aid in the queuing of the MRT System to ease congestion. |

Author (s): |
Ainie Khuriati, Wahyu Setia Budi, Muhammad
Nur, Istadi Istadi and Gatot Suwoto |
Abstract: |
This
study is aimed at developing an empirical model to estimate the heating
value of municipal solid waste as a function of its element content (C,
H, N, S, O). A correlation was developed using multiple stepwise
regression analysis based on 29 samples of municipal solid waste that
were randomly selected and gathered from 29 different areas in Semarang.
Experimental results show that carbon and hydrogen are statistically
significant predictors of the heating value. The model is HHV=
-2762.68+114.63C+310.55H kcal/kg (R2= 0.99 and Adj R2 =0.98).
Furthermore, this work also indicates that if only the C content is
known, the heating value can be estimated by HHV= -1737.55+143.33C
kcal/kg (R2= 0.94 and Adj R2 =0.94). These results show that the new
correlations using regression method give accurate and excellent results
that are closer to measured values. |

Shrouded kinetic turbines optimization for
run the river and tidal pico-hydropower |
Author (s): |
Robert Vincent Clarke |
Abstract: |
At
our current state of technological development, the designs being
proposed for the “channeling of a turbine” based on wind power, commonly
called DAWT (Diffuser-Augmented) or CWAT (Compact-Acceleration), utilize
a diffuser (divergent) shaped as an airfoil. Further developments of the
concept have brought about the introduction of other winged-profiled
ring structures behind or in front of the entrance to the divergent
making the design more complicated as well as more expensive due to the
difficulty of producing correct contours. Even though this results in an
increase in power, it usually is limited to slightly more than a
four-fold increase at most. In addition, brims (wing-lens) have been
recently added around the external edges of the diffuser. Nonetheless,
brims thus designed, are not suitable for use in a river due to the
significant stress that the structure as a whole needs to withstand. No
design, proposed until now, includes a convergent at the entrance to a
turbine due to the obstruction effect that it has on the flow of water
into the turbine, slowing it down and thereby reducing the acceleration
produced by the “channelizing” divergent. This article will introduce an
innovative convergent-divergent to which can be inserted a hydro-kinetic
turbine which will increase the maximum output power available 12.7
times compared with a free turbine. |

Modeling initial velocity profiles
for continuous free-vibrating beams using distributed impulse loading |
Author (s): |
Mustafa Kamal Al-Kamal and David J. Mukai |
Abstract: |
The
purpose of this paper is to develop an analysis method to solve the free
vibration response for a continuous system subjected to an initial
velocity profile using an initial velocity approximation based on an
equivalent impulse load. It has been shown that for a single degree of
freedom system, the initial velocity can be applied as an impulsive
loading with a very short duration. The proposed analysis method in this
paper is done for a continuous system to show that this approximation
works not only for a single degree of freedom system, but for a
continuous system as well. The assumed initial velocity profile is from
a case of interest to the authors. The available analytical solution for
a continuous system such as a simply supported beam subjected to an
initial velocity is compared with the finite element solution determined
from SAP 2000 using the initial velocity approximation. The SAP 2000
solution using the proposed approximation showed an excellent agreement
to the analytical solution. Finally, this method can be used to find the
dynamic response of complex frames subjected to an initial velocity
profile, where the analytical solution for such cases is difficult to
find. |

Author (s): |
K. Thamizhmaran, M. Anitha and
Alamelunachippan |
Abstract: |
Emerging technology allows the users to access information and services
anywhere regardless of their geographic location. Mobile Ad hoc Network
is the significant technology among various wireless communication
technologies where all the nodes are mobile and which can be connected
to dynamically used wireless link in a random manner. The
self-configuring ability of nodes in MANETs made it popular among
critical applications like military use or natural emergency recovery.
Most of the proposed protocols assume that all nodes in the network are
cooperative, and do not address any security issue. To adjust to such
trend, it is vital to address its potential security issues. The main
objective of this paper is to define the path for security and to
further improve throughput, routing overhead, packet delivery ratio and
at the same time to create energy enhanced way with excellent security.
Implementation of cryptographic algorithm for the information is done in
such a way that it is impossible for the attackers to knock the
resources of information sent on the web. In this paper, a new intrusion
detection system, Energy Efficient Enhanced Adaptive 3 Acknowledgement
(EE-EA3ACK), using EA3ACK with Elliptical curve cryptography is (ECC)
specially designed for MANET. In this ECC there is a two key encryption
technique based on elliptic curve based theory that can be used to
create faster, smaller, and more energetic and efficient cryptography.
Network Simulator (NS2) is used to implement and test the proposed
system. The proposed cryptography provides secured transmission, further
it reduces routing overhead, improves packet delivery ratio and
throughput. |

Automatic controlling system of the
blower’s speed for smoking area |
Author (s): |
Andrew Joewono, Rasional Sitepu, Yuliati,
Peter R. Angka and Richard I. A. |
Abstract: |
Nowadays, almost in every public room there is particularly a spot for
smokers and it is commonly called as smoking area. In order to keep the
condition of smoking area comfortable, it is installed blowers that
exhaust the smoke out of the room. However, the blower rotation is
usually in constant speed whiteout considering the amount of smoke.
Blower that rotates in constant speed will waste of electricity because
the smoking area is not all of the time full of smoke. This paper
presents a blower system using exhaust fan that rotation speed depends
on the volume of smoke in the room. If the smoke increase then blower’s
speed automatically increase, and vice versa if the level of smoke
decrease then the blower speed automatically decrease. The rotation
speed is controlled by implementing gas sensor MQ2 and, Zero Crossing
Detector, and Microcontroller Atmega8 technologies. The blower system
has three different speed levels, in which the speed is proportionately
linier with the smoke level in the area. Based on the tests, it is found
that the system has triggering delay time. The longer the triggering
delay occurs, the lower the rotation speed. |

Abstract: |
The
technical features in manufacturing press non-ferrous metal articles
have been considered via the Conform continuous pressing. Based on an
analysis of different types of press equipment, the absence of a
connection between the system for fastening the two-part container fixed
part (the shoe) and the working wheel shaft has been revealed as a
shortcoming specific to many Conform installations. This does not allow
observation of a controlled gap between the shoe and the groove bottom
during the operation of the installation, which, in turn, breaks the
stable feed of the bar billet into the die. The purpose of this
operation is to develop a system for fastening the shoe that ensures the
stable continuous metal extrusion process. Meanwhile, the task has been
set of creating a tough and strong connection between the shoe and the
working wheel shaft with the levers and drafts system that reduces the
load of the bearings in the housing posts in which the wheel shaft
rotates. As a result, the original technical solution of the Conform
installation press unit has been developed. The practical use of the
design presented in this work will open up new possibilities for
manufacturing pressed metal non-ferrous metal products with a
permanently high level of properties. |

clusters and administrators. Along these outlines, a significant issue
in live migration is the complete migration time and the downtime. To
enrich the concert of live migration, an optimized iterative pre-copy
procedure is used to decrease the dirty rate of virtual machines. In
pre-copy approach that is essentially utilized as a part of live
migration, total migration time, which influence on the performance of
VM, is delayed by iterative copy operations and the noteworthy measure
of transferring data during the entire migration process. In this paper,
we presented a system that incorporates pre-processing phase in
traditional pre-copy based live migration for decreasing the amount of
transferred data. In pre-processing stage, we recommend the prediction
working set algorithm to show that complete migration time as well as
downtime is controlled by specific memory utilization patterns. Applying
the proposed lazy counting based splay tree algorithm, the system can
diminish the amount transferred memory page. The lazy counting-based
splay algorithm along with traditional pre-copy approach that contains a
pre-processing phase for diminishing the amount of transferring memory
page and total migration time. |

Design and development of fuzzy based
reliable scheme for energy efficiency in MANET |
Author (s): |
N. Suresh Kumar and S. Bhavani |
Abstract: |
Ad
hoc network plays a major role in wireless networks where it does not
have any access point. Reliability is a major issue in Mobile Ad hoc
Network (MANET) which influences the network performance. Links and
nodes are the major part of ad hoc network. To keep network stable,
links and nodes must be kept stable and reliable. Mobility of nodes
affects the reliability of ad hoc network. In this research work, we
designed and implemented the Reliability based Stable Scheme (RSS) to
attain maximum throughput. Link reliability and node reliability are
calculated based on capacity and mobility metrics. In this connection, a
reliability model is created to attain maximum performance. Based on the
analysis using simulation tool, the proposed scheme provides better
results than existing schemes in terms of jitter, throughput, packet
delivery ratio and Network reliability. |

Title: |
Hybrid model for adaptive noise cancellers
in ICG using modified non negative algorithms |
Author (s): |
Madhavi Mallam and K. Chandra Bhushana Rao |
Abstract: |
In
this paper, a new process of adaptive artifact elimination from
Impedance Cardiography (ICG) signals is proposed. This is a composite
model based on wavelet decomposition and adaptive filter. The prime
feature of this type methodology is the realization of adaptive noise
canceller (ANC) without any reference signal. The proposed model is able
to generate a reference signal from the input signal itself with the
help of wavelet transforms. In the real time medical environment during
critical conditions due to heart rhythm disorders the filter
coefficients may become negative. This makes the convergence unbalance,
leads to low filtering capability. In order to solve this problem, we
incorporate non-negative adaptive algorithms in the proposed ANC. To
enhance the performance of ANC, error normalization is adapted to change
filter coefficients automatically. Again, in order to minimize
computational complexity and to avoid overlapping of data samples at the
input stage of the filter a hybrid version of non-negative and sign
based algorithms is considered for implementation. The resulting hybrid
versions are error normalized nonnegative least mean square (EN3LMS)
algorithm, error normalized non negative sign regressor LMS (EN3SRLMS)
algorithm, error normalized non negative sign error LMS (EN3SELMS)
algorithm and error normalized non negative sign sign LMS (EN3SSLMS)
algorithm. Finally, various ANCs are developed using these algorithms,
performance measures are computed and compared. All the implemented ANCs
are tested on real impedance cardiogram signals. |

by using dynamic P-Box and S-Box (DPS method) based on modular
calculation and key encryption |
Author (s): |
M. Zobeiri and B. Mazloom-Nezhad Maybodi |
Abstract: |
Through the passage of time, computer technology has been considered as
a pivotal element in human life. Because of this point, it is more
evident that information security gained a prominent position.
Cryptography is utilized to secure information in a way that information
became impenetrable under attack. In this paper, a new method of
encryption is introduced according to dynamic P-Box and S-Box based on
modular calculation and key encryption. P-Box is a tool that changes the
order of the input bits and they appear in the output. In this case, the
key is order transmission of input bits in output bits. An S-box is a
basic component which performs substitution. In this paper, a new method
for the production of encryption method with the help of modular
computing is introduced. This method called DPS method which in its
P-boxes and S-boxes the order of the input bit transfer in output, are
the function of the encryption key. |

Author (s): |
Rajesh Nayak and Raviraj Shetty |
Abstract: |
Many
industries and academic centers are looking for alternatives to improve
the manufacturing quality, performance of the tool, optimum cutting
conditions and cost reduction that help for better understanding of the
metal cutting process. One of these alternatives is the Finite element
method. The inelastic-plastic finite element method is established in
this learning to examine the influence of the tool rake angle on the
cutting force, chip contour, total energy and stress developed in
machined work piece during the precision orthogonal turning process of
elastomer. The results specify that an increase in the tool rake angle
evidences to reduction in the cutting force established, smoother chip
contour and a decrease in the total energy of the turning process under
different cutting speeds. |

Abstract: |
The
increase in population numbers lead to the high quantity of domestic
wastewater and potentially contaminates the environment. Domestic
wastewater management in Depok City, Indonesia was carried out by
on-site system, but it was not managed properly. That is described by the
high number of households did not desludge their septage and the high of
idle capacity of STP. One solution is a regular desludging as a solid
way to prevent any further contamination and to make sure all septages
should be treated in STP. The purpose of the study is to optimize the
city septage desludging service as a step to design a good septage
management. The findings of this study is the regular
septage desludging service that has to be implemented to serve 63,598
households and the need of six unit vacuum trucks to cover the city
central region. The use of small vehicle and transfer station as
additional facilities should be considered to cover limited area and

polymorphism with glutathione plasma level in pulmonary tuberculosis
patients |
Author (s): |
Ari Yuniastuti Irawan Yusuf, Muh Nasrum
Massi and Budu |
Abstract: |
Genetic polymorphism of glutamate-cysteine ligase (GCL) could lead the
changes in GCL enzyme activities. These changes could disrupt
glutathione synthesis allowing the reduction of glutathione level.
Furthermore, the decrease of glutathione level would change the
phenotype and allow the defenselessness against some diseases. The aim
of this study was to determine the relationship between genetic
polymorphism of the -129C/T promoter region in glutamate-cysteine ligase
sub unit catalytic (GCLC) genes with glutathione plasma level in
pulmonary tuberculosis patients. A prospective cohort study was
conducted to study this association. The samples were obtained from the
center of health lung community (BBKPM) and Labuang Baji Hospital,
Makassar, Indonesia in accordance with the inclusion and exclusion
criteria. The consecutive sampling technique was accomplished based on
the order of arrival of the patient. Analysis of genetic polymorphism
and glutathione level in pulmonary tuberculosis patients were performed.
The results of study indicated that genetic polymorphism of C/C was
increased by 11% in genotype C/C whereas in genotype C/T was decreased
by 32%. According to the results, the polymorphisms of GCLC gene were
associated with glutathione level in pulmonary tuberculosis patients. |

Abstract: |
Distributed Embedded systems are being used these days for monitoring
and controlling many applications which are either critical or
non-critical. No formal frameworks as such have been presented which can
be used for testing the distributed embedded systems. Many approaches
have been presented in the literature for testing stand alone embedded
systems which include testing through scaffolding, assert macros,
instruction set simulators, logic analyzers, in-circuit emulators,
monitors etc, It has to be explored to find how best these methods can
be used for testing the distributed embedded systems. In this paper, an
investigation on use of asserts macros for testing the distributed
embedded system is presented. The method has been used to test existing
distributed embedded systems that monitors and controls temperatures
within a Nuclear reactor system. |

Prediction of mechanical properties of
alccofine activated low calcium fly ash based geopolymer concrete |
Author (s): |
Bharat Bhushan Jindal, Sanjay K. Sharma,
Dhirendra Singhal and Parveen |
Abstract: |
Geopolymer concrete was developed with the intention to protect the
environment from the carbon dioxide which liberates to the environment,
as well as nature is harmed. However, geopolymer concrete had a severe
limitation that silica of fly ash, which was activated through alkaline
solution, could achieve required compressive strength only at high
temperature. In the present investigation alccofine which is richer in
silica and finer than fly ash has been added up to 10% of fly ash and
geopolymer concrete with different fly ash content has been produced.
The results are encouraging, as required compressive strength even 40MPa
could be achieved at ambient temperature. Compressive and tensile
strength have increased with increase in fly ash and alccofine content.
The strength further increased significantly up to 90% in the presence
of alccofine. Attempts were further made to relate the compressive and
tensile strength in the presence of alccofine. A relationship has been
suggested which holds good for geopolymer concrete with and without
alccofine at ambiently, and heat cured specimens. |

Author (s): |
Mehush Aliu, Sadija Kadriu, Luljeta Pula
Beqiri, Milaim Sadiku, Ismet Mulliqi and Mensur Kelmendi |
Abstract: |
After
Drin, Sitnica is the longest river in the territory of Kosovo. Since the
source, the southeastern part of Kosovo until its unification with the
River Iber in the western part of Kosovo, the waters of the Sitnica, in
the road with a length of 90 km, pass peacefully in the bed of the river
in an field area. This river is characterized by annual flow of water of
16.6 m3/s, while in the summer months the water flow which discharge on
the river Iber falls up to 2.35 m3/ s. Since the Vragoli village, in
Fushe Kosove, until his discharge in the river Iber, the waters of this
river polluted by various anthropogenic sources, such as households,
various preparations and agricultural chemicals and industrial
discharges. For the compilation of this work, we started by the needs of
identification of different pollutants of water quality of the river
Sitnica, based on physical-chemical parameters and for this reason we
have selected six monitoring points. During our research we have
achieved to ascertain that the rivers, as Graqanka, Drenica Prishtevka
together with Ferronikel, Kosovo Corporation Energy, industrial waste of
Industrial Park in Mitrovica and Trepça Mines are most potential
pollutants of waters of the river Sitnica. |
