A Novel Marker Based Interactive Image Segmentation Method

Abstract
| Pages: 13-18
An important branch of computer vision is image segmentation. Image segmentation aims at extracting meaningful objects lying in images either by dividing images into contiguous semantic regions, or by extracting one or more specific objects in images such as medical structures. The image segmentation task is in general very difficult to achieve since natural images are diverse, complex and the way we perceive them vary according to individuals. For more than a decade, a promising mathematical framework, based on variational models and partial differential equations, have been investigated to solve the image segmentation problem. The proposed scheme is simple yet powerful and it is image content adaptive. With the similarity based merging rule, a two stage iterative merging algorithm was presented to gradually label each non-marker region as either object or background. We implemented the MSRM algorithm in the MATLAB.

Abstract
| Pages: 19-23
This paper presents the methods to reduce dynamic power consumption of a digital Finite Imppulse Respanse (FIR)filter these methods include low power serial adder, combinational booth multiplier And low-powerdelay buffer. The proposed delay buffer uses several new techniquesto reduce its power consumption. Since delay buffers are accessed sequentially, it adopts a ring-counter addressing scheme. In the ring counter, double-edge-triggered (DET) flip-flops are utilized to reduce the operating frequency by half and the C-element gated-clock strategy is proposed. A novel gated-clock-drivertree is then applied to further reduce the activity along the clock distribution network. Moreover, the gated-driver-tree idea is also employed in the input and output ports of the memory block to decrease their loading, thus saving even more power. folding transformation in linear pheasarchitecture and applied to firfilters to power consumption reduced thus reduce power consumption due to glitching Is also reduced. The proposed FIR filters were synthesized implemented using Xilinx ISE Virtex IVFPGA and power is analized using Xilinx XPower analyzer.

The Insurance industry forms an integral part of the Indian financial market, with insurance companies being significant institutional investors. In recent decades, the insurance sectors, like other financial services, have grown in economic importance. The insurance sector, along with other elements of marketing, as well as financial infrastructure, have been touched and influenced by the process of liberalization and globalization in India, every company is trying to implement new creations and innovative product characteristics to attract the entry of private players, the competition is becoming intense. Today numerous public and private insurance companies are providing Life Insurance Services to a large number of clientele and there has been mushroom growth in their numbers and size in India. There is a transition from “sellers market  to “buyers market . The efficiency of insurance sector depends upon how best it can deliver services to its target customers and how far expectations of customers are met. The major objectives of this research are to ascertain the socio-economic profile of sample respondents and identify the determinants of satisfaction of policyholders in private life insurance companies. Methodology of this study is based on the analysis of the data collected from three hundred individual policy holders by using interview schedule method. The interview schedule was kept respondent friendly to make a quality of questionnaire. Interview schedule was the main tool used to collect the pertinent data from the selected sample respondents. Primary data has been collected for this present study. The primary data was collected from three hundred sample respondents from Tirupur district, by adopting simple random sampling method. Through the analysis of the study, it is identified that Marital Status and Number of Policies are found to be associated with policy holder’s satisfaction. To conclude this study, is an attempt to measure the various parameters as perspective by the policy holders and to help the insurance company in serving its policy holders in a much better and efficient manner.

Computational Analysis and Design for Precision Forging Of Aluminium AA 6061 Connector

Abstract
| Pages: 36-43
Development of a new process methodology which satisfies given criteria is a big challenge faced by most of the forging industries. The domain of competition is quite large and hence every firm aims at producing near net shapes thereby eliminating the need for machining and other secondary operations. The present investigation deals with the flow simulation of Aluminium forgings conforming to AA 6061 specification and henceforth studies the mechanical characteristics of the flow simulation results. The Aluminium AA 6061 component considered is precision forged with a hydraulic press in a die having geometrical interlocking. During precision forging it was difficult to achieve the required net shape of the component because of unsymmetrical location of small ribs on cylindrical surface and variation in the cross sections from bottom to top (i.e. unsymmetrical about both X & Y axis). Thus to eradicate the problem encountered, the flow simulation of the precision forging process was carried out and the mechanical characteristics of the flow simulation results obtained were studied.

Abstract
| Pages: 44-62
Experimental and numerical studies are investigated to study the two-phase flow phenomena around straight hydrofoil for different angle of attacks in a rectangular enlarging channel which has the dimensions (10 ï‚´ 3 ï‚´ 70 cm) enlarged from assembly circular tube of the two phases. Experiments are carried out in the channel with air-water flow with different air and water flow rates. These experiments are aimed to visualize the two phase flow phenomena as well as to study the effect of pressure difference through the channel with the existence of the hydrofoil. All sets of the experimental data in this study are obtained by using a pressure transducer and visualized by a video camera for different water discharges (20, 25, 35 and 45 l/min), different air discharges (10, 20, 30 and 40 l/min) and different angle of attack (0, 15 and 30 degree). While the numerical simulation is conducted by using commercial Fluent CFD software to investigate the steady and unsteady turbulent two dimensional flows for different air and water velocities. The results show that when the angle of attack increases at constant air and water discharge or when air discharge increases with constant water discharge and angle of attack or when water discharge increases with constant air discharge and angle of attack, the pressure difference increases at the inlet and the outlet of the rectangular channel.

Abstract
| Pages: 63-67
Peer-to-peer overlay networks are widely used in distributed systems. P2P is a popular technology used for file sharing. File replication and Consistency maintenance are the techniques used in P2P for high system performance. The objective of this work is to design a hybrid peer-to-peer system for distributed data sharing which combines the advantages of both types of peer-to-peer networks and minimizes their disadvantages. However, in peer-to-peer networks, Information Retrieval (IR) performance is determined by both technology and user behavior, and little attention has been paid in the literature to improving IR performance through incentives to change user behavior.The proposed hybrid peer-to-peer system is composed oftwo parts: the first part is a structured core network the second part is multiple unstructured peer-to-peer networks each of which is attached to a node in the core network.Our cachingscheme can deliver lower query delay, better load balance and higher cache hit ratios.

Abstract
| Pages: 68-73
Water resources of a hydro power plant generally is influenced by rainfall in the watershed. Rainfall prediction is done by using monthly rainfall data at each station. Water resources are usually derived from some streams that flow into the hydropower reservoirs. The research was conducted by predicting rainfall at three locations. These locations are considered to have a very large impact on water resources of the plant. The method used is the time series.
