Performance Evaluation of DSDV and MDSDV Routing Protocol with Varying Node D...IJERA Editor
Mobile Ad Hoc Networks (MANET) is an important and challenging research area. The routing protocol should detect and maintain a good route between source and destination nodes in these dynamic networks. Many routing protocols have been proposed for mobile ad hoc networks, and none can be considered as the best under all conditions. This thesis work consist a systematic comparative evaluation of a new multipath routing protocol for MANETS. The new protocol, called Multipath Destination Sequenced Distance Vector (MDSDV) is based on the well known single path Destination Sequenced Distance Vector (DSDV) is compared with known protocol DSDV. This work containing evaluates the protocols on a range of MANETS with between 50, 75 and 100 nodes, which are static nodes. The protocol comparison metrics are Throughput and Residual Energy.

A comparative study of the impact of citrate of manganese, obtained with the help of nanotechnology, on the growth of mycelium of medicinal fungus Trametes versicolor on their cultivation in a liquid media. It was demonstrated that sulfate and citrate manganese have dramatically different effects on the growth of mycelium Trametes versicolor depending on which medium they were added to.
Evaluation of sub-soil geo-electric properties in a proposed power sub-statio...IJERA Editor
Electrical resistivity survey was carried out in a site proposed for the construction and installation of a Power sub-station. The project will involve subsurface installation of cables and other objects that easily conduct electricity. Extant laws including EIA also require knowledge of subsurface distribution of resistivity in construction projects that would involve burial of steel pipes and cables. The imperative of this is emphasized by the location of the project in an area of shallow groundwater conditions. Field resistivity measurements were undertaken using ABEM Terrameter SAS 1000, adopting Schlumberger configuration in vertical electric sounding at 12 locations within the study site. The results were used to generate geo-electric log models. Three geo-electric profile models (pseudo- profiles) were also taken NE-SW of the site. Interpretation of the models shows that the area is characterized by two geo-electric layers to the depth of 30m. The upper layer of lower resistivity occurs to a depth of 2-3m. This layer consists of lateritic to silty sands. The lower layer has a resistivity of between 900 - >2000 Ωm and represents fine to coarse sands and gravels. On the Soil Electrical Resistivity Classification (BS 1377), the subsoil falls within non-corrosive class. Objects installed in the soil are not likely to suffer corrosion soon. Similarly, subsurface electrical installations will pose minimal hazards and would require basic precautions to avoid electrical accidents.
DESIGN OF A LOW POWER MULTIBAND CLOCK DISTRIBUTION CIRCUIT USING SINGLE PHASE...IJERA Editor
The clock distribution network consumes nearly 70% of the total power consumed by the integrated circuit since
this is the only signal which has the highest switching activity. Normally for a multiband clock domain network
we develop a multiple PLL to cater the need. This project aim for developing a low power true single phase
clock(TSPC) multiband network which will supply for the multi clock domain network. In this paper, a wide
band 2/3 prescaler is verified in the design of proposed wide band multimodulus 32/33/47/48 or 64/65/78/79
prescaler. A dynamic logic multiband flexible integer-n divider based on pulse swallow topology is proposed
which uses a low power wide band 2/3 prescaler and a wide band multimodulus 32/33/47/48 or 64/65/78/79
prescaler. Since the multimodulus 32/33/47/48 or 64/65/78/79 prescaler has a maximum operating frequency of
6.2GHz, the values of P and S counters can actually be programmed to divide over the whole range of
frequencies. However the P and S counter are programmed accordingly. The proposed multiband flexible
divider also uses an improved loadable bit cell for swallow counter and consumes a power of 0.96 and 2.2mW.
This project is highly useful and recommended for communication applications like Bluetooth, Zigbee, IEEE
802.15.4 and 802.11 a/b/g WLAN frequency synthesizers which are proposed based on pulse swallow topology.
This design is modelled using Verilog simulated tool „MODELSIM 6.4b‟ and implemented and synthesized
using „Xilinx ISE 10.1‟.
Behaviour of M30 Grade concrete with confinement under axial compressionIJERA Editor
The strength and durability of concrete have undergone continuous improvement. Over the years and these
improved materials are now commonly used. In the present experimental investigation the behaviour of M30
grade concrete with and without confinement for different percentages of replacement of silica fume is studied
under axial compression as per IS mix design. The 150mm x 300mm cylindrical specimens were cast with and
without confinement and investigating the mechanical properties like axial compressive strength and stress –
strain behaviour. It was observed that the confinement of concrete has increased the 28days strength for
different percentages of confinement and that the peak stress and corresponding strain at peak stress increased
with increase in percentages of confinement

Thermo catalytic decomposition of methane over Pd/AC and Pd/CB catalysts for ...IJERA Editor
Hydrogen production studies have been carried using Thermo Catalytic Decomposition (TCD) Unit. Thermo catalytic decomposition of methane is an attractive route for COx free production of hydrogen required in fuel cells. Although metal based catalysts produce hydrogen at low temperatures, carbon formed during methane decomposition reaction rapidly deactivates the catalyst. The present work compares the results of 10 wt% Pd supported on commercially available activated carbon and carbon black catalysts (samples coded as Pd10/AC and Pd10/CB respectively) for methane decomposition reaction. Hydrogen has been produced by thermo catalytic decomposition of methane at 1123K and Volume Hourly Space Velocity (VHSV) of 1.62 L/h g on the activity of both the catalysts has been studied. XRD of the above catalysts revealed, moderately crystalline peaks of Pd which may be responsible for the increase in catalytic life and formation of carbon fibers. Also during life studies (850°C and 54 sccm of methane) it has been observed that the activity of carbon black is sustainable for a longer time compared to that of activated carbon.
Towards Improving Crash Data Management System in Gulf CountriesIJERA Editor
Scientific and analytical approaches to accident data collection, storage and analysis are essential in dealing with road safety problems. Police accident records in the majority of countries form the main (and sometimes the only) source of accident data. Access to the accident database is also important to identifying specific safety problems and evaluating the effectiveness of the countermeasure introduced. Accident data collection and analysis offered by technological innovation such as Electronic Data Entry (EDE), Electronic Data transfer (EDT), and Geographic Information system (GIS) are implemented in developed countries. Developing countries, including the Gulf countries, should take advantage of the experience of developed countries on how the advance accident data management system works to identifying, more accurately, the main factors contributing to traffic accident. The main purpose of this research is to provide information on accident statistics process in Virginia state, starting from the time of accident occurring until it is stored in the database, with the aim of using it towards improving the process of collecting and maintaining accident data system in Gulf countries. The task is performed by reviewing the relevant international literature and interviewing police officers in charge and academic researchers in order to compare the accident data management system and also the quality of the data. Recommendations towards developing the crash data management system will be obtained based on the research results and international experience.
This presentation was given as a part of the Microsoft eScience panel discussion in Sao Paulo, Brazil. The panel discussion was in regards to Going Native, a reference to a quote from Jim Gray along the lines of “in order to really understand the computing needs of a scientist you have to go native”. Jim himself did this, immersing himself in astronomy to build what would become the WorldWide Telescope. Bridging the gap between experimental scientists and the computing that underpins their discoveries is an ongoing challenge for eScience. The panel explored what it means to go native and gave examples of where they have seen this work well and shared lesson’s learned from working in this way.
A Novel Hybrid Dstatcom Topology for Load Compensation with Non-Stiff SourceIJERA Editor
The distribution static compensator (DSTATCOM) is a shunt active filter, which injects currents into the point
of common coupling (PCC) (the common point where load, source, and DSTATCOM are connected) such that
the harmonic filtering, power factor correction, and load balancing can be achieved. The distribution static
compensator (DSTATCOM) is used for load compensation in power distribution network. A new topology for
DSTATCOM applications with non-stiff source is proposed. The proposed topology enables DSTATCOM to
have a reduced dc-link voltage without compromising the compensation capability. It uses a series capacitor
along with the interfacing inductor and a shunt filter capacitor. With the reduction in dc-link voltage, the
average switching frequency of the insulated gate bipolar transistor switches of the D-STATCOM is also
reduced. Consequently, the switching losses in the inverter are reduced. Detailed design aspects of the series and
shunt capacitors are discussed in this paper. A simulation study of the proposed topology has been carried out
using MATLAB environment and the results analyzed.
