An Efficient Photo Voltaic System for Onboard Ship Applications
In this paper a high efficient photovoltaic system is proposed for onboard ship applications which convert the
lower voltage obtained from solar modules to higher voltage required by the ship service loads. In a typical
photovoltaic system only step-up /boost converter is used due to which the converter has to operate in extreme
duty ratio, resulting in increase of switching losses and thus decreasing the overall efficiency. But in this paper
the conventional boost converter is used with interleaved inductors and capacitors. The poposed system stores
the energy in inductors and thus reduces the stress in the switches (Without allowing the total voltage to appear
across the switch). The simulation is designed using MATLAB/Simulink with an Input voltage of 40-V to
achieve a output voltage of 300-380 V. The developed simulation results are compared for output powers of
500W and 1kW

Some Remarks on Prime Submodules in Weak Co-Multiplication Modules
Throughout this paper, the entire ring will be treated as commutative ring with non-zero identity and all the
modules will be treated as unitary modules. In this paper we shall discuss some remarks on prime submodules in

Groundwater Quality Assessment in hard rock terrain of Rasipuram Taluk, Namak...
Groundwater is of most important to rural development in many countries of the world. Over exploitation of
groundwater has become a major challenge not only to the present civilization and also for the future
generations. The main focus of this study is to assess the suitability of groundwater quality for drinking and
irrigation purposes in vicinity of Rasipuram block in Tamil Nadu. Groundwater samples from 15 locations were
collected from different wells during January 2015 and analyzed for different physico-chemical parameters. The
usefulness of these parameters in predicting groundwater quality characteristics were discussed. The quality of
groundwater in the study area is fresh to brackish water, moderately hard to very hard in nature. The piper plot
shows that the most of the groundwater samples fall in the field of Na+-Cl- and mixed Ca++-Na+-Cl- type. Water
quality index rating was carried out to quantify overall groundwater quality status of the area. The WQI for these
samples ranges from 37.34 to 650. Hence majority of the water samples are poor to very poor in water quality.
The area in general is characterized by hard water, hence is not suitable for drinking purpose. The samples
plotted in the piper and USSL diagram were used to understand the chemical characteristic of groundwater for
irrigation purposes. However, the values of SAR, Na% and RSC indicate that groundwater is suitable for
irrigation purposes. Overall water quality of the study area was found satisfactory for drinking purpose except in
few locations and suitable for irrigation purpose. Hence the local government needs to initiate remedial
measures.
Study on Theoretical Aspects of Virtual Data Integration and its Applications
Data integration is the technique of merging data residing at different sources at different locations, and
providing users with an integrated, reconciled view of these data. Such unified view is called global or mediated
schema. It represents the intentional level of the integrated and reconciled data. In the data integration system,
our area of interest in this paper is characterized by an architecture based on a global schema and a set of
sources or source schemas. The objective of this paper is to provide a study on the theoretical aspects of data
integration systems and to present a comprehensive review of the applications of data integration in various
fields including biomedicine, environment, and social networks. It also discusses a privacy framework for
protecting user’s privacy with privacy views and privacy policies.
Design of Digital Adder Using Reversible Logic
Reversible logic circuits have promising applications in Quantum computing, Low power VLSI design,
Nanotechnology, optical computing, DNA computing and Quantum dot cellular automata. In spite of them
another main prominent application of reversible logic is Quantum computers where the quantum devices are
essential which are ideally operated at ultra high speed with less power dissipation must be built from reversible
logic components. This makes the reversible logic as a one of the most promising research areas in the past few
decades. In VLSI design the delay is the one of the major issue along with area and power. This paper presents
the implementation of Ripple Carry Adder (RCA) circuits using reversible logic gates are discussed.
Experimental Study on Two-Phase Flow in Horizontal Rectangular Minichannel wi...
An experimental study was conducted to investigate two-phase air-water flow characteristics, in horizontal
rectangular minichannel with Y-junction. The width (W), the height (H) and the hydraulic diameter (DH) of the
rectangular cross section for the upstream side of the junction are 4.60 mm, 2.50 mm and 3.24 mm, while those
for the downstream side are 2.36 mm, 2.50 mm and 2.43 mm. The entire test section was machined from
transparent acrylic block, so that the flow structure could be visualized. Liquid single-phase and air-liquid twophase
flow experiments were conducted at room temperature. The flow pattern, the bubble velocity, the bubble
length, and the void fraction were measured with a high-speed video camera. Pressure profile upstream and
downstream from the junction was also measured for the respective flows, and the pressure loss due to the
contraction at the junction was determined from the pressure profiles. Two flow patterns, i.e., slug and annular
flows, were observed in the fully-developed region apart from the junction. In the analysis, the frictional pressure
drop data, the two-phase frictional multiplier data, bubble velocity data, bubble length data and void fraction data
were compared with calculations by some correlations in literatures. In addition, new pressure loss coefficient
correlations for the pressure drop at the junction has been proposed. Results of such experiment and analysis are
described in the present paper.
Effect of Algal Bio-fertilizer on the Vigna radiata: A Critical Review
The continuous increasing demand of food crops and decrease in productivity due to continuous use of chemical
fertilizer has not only resulted in decline of crop yield, loss of fertility and degradation of soil but has also led us
one step back in achieving sustainable agriculture. The use of algal bio-fertilizer provides an effective, ecofriendly
and non-polluting approach in improving the productivity of crop by both nitrogen fixation and
photosynthesis. Algal bio-fertilizers improve soil structure and increase yield productivity even if applied in a
small area. The application of algal bio-fertilizers in plants has resulted in increase in root, shoot length with
number of leaves and hence overall growth of the plant has been increased. India being one of the largest
producer and consumer of pulses requires abundant amount of pulse production to fulfil the demands of ever
growing populations which can be achieved by using algal bio-fertilizers. This paper briefly underlines the usage
of algal bio-fertilizers as an important tool for sustainability and alternative usage against the chemical
fertilizers.
Nanofluid Flow past an Unsteady Permeable Shrinking Sheet with Heat Source or...
The consideration of nanofluids has been paid a good attention on the forced convection; the analysis focusing
nanofluids in porous media are limited in literature. Thus, the use of nanofluids in porous media would be very
much helpful in heat and mass transfer enhancement. In this paper, the influence of variable suction, Newtonian
heating and heat source or sink heat and mass transfer over a permeable shrinking sheet embedded in a porous
medium filled with a nanofluid is discussed in detail. The solutions of the nonlinear equations governing the
velocɨty, temperature and concentration profiles are solved numerically using Runge-Kutta Gill procedure
together with shooting method and graphical results for the resulting parameters are displayed and discussed.
The influence of the physical parameters on skin-friction coefficient, local Nusselt number and local Sherwood
number are shown in a tabulated form.
