Image segmentation plays vital role in computer vision for image retrieval, visual summary, image base modeling, and for many other purposes. Despite many years of research and significant contributions, image segmentation is still a very challenging task to suit for variety of applications. Among the different segmentation approaches, graph theoretical approach is the most popular since it has capabilities of organizing the image elements into accurate mathematical structures and makes the formulation computationally efficient This paper critically reviews recent graph based segmentation methods along with their detailed analysis, experimental performance and evaluation on the basis of Berkeley benchmark The study and evaluation is useful in improving the performance of existing methods as well as helpful in the development of new methods. © 2014 IEEE.

Low efficiencies and costly electrode materials have limited harvesting of thermal energy as electrical energy using thermo electrochemical cells (or "thermocells"). VVe demonstrate chermocells, in practical configurations (from coin cells to cells thai can be wrapped around exhaust pipes), that harvest low-grade thermal energy using relatively Inexpensive carbon multiwalled nanotube (MWNT) electrodes. These electrodes provide high electrochemically accessible surface areas and fast redox-mediated electron transfer, which significantly enhances thermocell current generation capacity and overall efficiency. Thermocell efficiency is further improved by directly synthesizing MWNTs as vertical forests that reduce electrical and thermal resistance at electrode/substrate junctions. The efficiency of thermocells with MWNT electrodes is shown to be as high as 1.4% of Carnot efficiency, which is 3-fold higher than for previously demonstrated thermocells. With the cost of MWNTs decreasing. MWNT-based thermocells may become commercially viable for harvesting low-grade thermal energy. © 2010 American Chemical Society.

Highly efficient arithmetic operations are necessary to achieve the desired performance in many real-time systems and digital image processing applications. In all these applications, one of the important arithmetic operations frequently performed is to multiply and accumulate with a small computational time (delay). As in all the arithmetic operations, it is the squaring which is most important in finding the transforms or the inverse transforms in signal processing. The squaring operation occupies most of the computing time; therefore, it becomes imperative to concentrate on improving the speed with which we square the numbers. The squaring operation also forms the backbone in cryptography. In this paper, we propose a technique for implementing squaring operation using Vedic methods in VHDL and evaluate the performance. The results are compared with the conventional Booth's algorithm in terms of time delay and area occupied on the Xilinx Virtex 4vlx15sf363-12. Copyright © 2011 by the IETE.

Models are important artifacts in the software development life-cycle and often to produce results on which multiple developers has to work collaboratively, especially with the adoption of Model-Driven Development. If a modeling task is distributed, it will frequently be necessary to merge models developed by different team members. When multiple developers work over diagrams of modules of the same project while integrating those modules conflicts can occur and need to be resolved by merging. Existing approaches for model merging require developers to solve all conflicts manually before commit. Sometimes conflicts increases more because of manual commitment. And existing approaches while merging make assumptions about the types of model to be merged, and the nature of the relationship between them. In this paper, we propose a simple model merging approach for two different diagrams of same model. This facilitates resolution of conflicts and merging. In this paper, we describe proposed algorithm for transforming different software design models to XML and vice versa and we also describe proposed algorithm for model merging along with experimental results. © 2012 IEEE.

With the advance of network technology digital communication has become an essential part of infrastructure nowadays. The Internet is widely used as a channel for communication and information transfer. The network security is becoming more important as the amount of data being exchanged on the Internet is increasing. Security requirements are necessary for the information transmitted which requires features of security like confidentiality, identification, non repudiation, integrity control and availability from the sender level up to the receiver level. This has resulted in an explosive growth of the field of information hiding, by providing secured communication between two or more computers, for exchanging confidential data like credit card numbers, usernames, passwords and tender amount etc. by preventing hackers from hacking the confidential data. This paper proposes a system that provides a novel method for secure data transmission using steganography by hiding data in TCP/IP header. Copyright © 2011 ACM..

Our faces are complex objects with features that can vary over time. However, we humans have a natural ability to recognize faces and identify persons in a glance. Unfortunately, this natural ability does not exist in machines, so we need to create intelligent autonomous machines to simulate recognition system artificially. We have implemented intelligent machine for face recognition. A discriminative and robust feature - -kernel enhanced informative Genetic Algorithm based Gabor feature is proposed in this paper for face recognition. We have used Genetic Algorithm approach for selection of parameter of Gabor filter. We proposed optimization function for selection of parameters of Gabor in this paper. Experiments have been conducted on face and non face images from the ORL database. The method was tested on several images from ORL database and experimental results were great. Copyright 2010 ACM.

To run any application we need to first download the setup file/s and then install it on the system. License costs, download and installation time costs are very high. Economically, this limits the number of applications that can be accessed on a system. In an organization, the challenges include installing the same application on multiple computers, accommodating multiple versions of the same application as well as u pdating application packages on multiple computers. APPOX is a technology that enables the organizations to respond to these management challenges by providing the server the capability to dynamically stream the applications to multiple clients over a network. We know that software developers modularize large applications into several distinct files and we also know that, in a computer, every hardware device is independent of another. Based on these two facts, in this paper, we show how APPOX serves the purpose of letting clients use various applications without installing them on their machines. This form of delivery uses the clients's local computing resources to run the application and enables users to take applications with them even while they are disconnected from the network. This technology lets the server stream only parts of the application that need to be available at any instance for the end user to perform a particular function. Our experimental results show that, on Fedora 8 (Linux Kernel Version 2.6.28), APPOX can be successfully implemented for a Text Editor (MP-5), a Music Player (Rhythmbox), a Video/Music Player (Totem Player), a Graphic image editing/processing tool (GIMP) and a Pdf Reader (Document Viewer). © 2010 IEEE.

Home automation is a common field of interest for engineers, researchers and of course, consumers. Today, home automation systems are commonly found in many homes across many countries around the world. Such systems not only offer a high level control over home appliances, but also try to reduce the wastage of electricity. Powerline communication (PLC) is a popular technique employed in home automation systems that reuses household electrical wiring for communication. But the current systems have some drawbacks and need improvement. Our paper describes the design of a next generation home automation system that will provide great features to consumers as well as electricity distributors. The main features of this system are web based control and data-logging facility. © 2011 IEEE.

Multiple Sclerosis is a multifactorial disease with several pathogenic mechanisms and pathways. Successful MS management and medical care requires early accurate diagnosis along with specific treatment protocols based upon multifunctional nanotechnology approach. This paper highlights advances in nanotechnology that have enabled the clinician to target the brain and CNS in patient with multiple sclerosis with nanoparticles having therapeutic and imaging components. The multipartite theranostic (thera(py) + (diag)nostics) approach puts forth strong implications for medical care and cure in MS. The current nanotheranostics utilize tamed drug vehicles and contain cargo, targeting ligands, and imaging labels for delivery to specific tissues, cells, or subcellular components. A brief overview of nonsurgical nanorepair advances as future perspective is also described. Considering the potential inflammatory triggers in MS pathogenesis, a multifunctional nanotechnology approach will be needed for the prognosis. © 2012 Ajay Vikram Singh et al.

Multiple sclerosis (MS) is an autoimmune neurological disorder, which has impacted health related quality of life (HRQoL) more intensively than any other neurological disorder. The approaches to improve the health standard in MS patient are still a subject of primary importance in medical practice and seek a lot of experimental exploration. The present review briefly explains the anomaly in neuron anatomy and dysfunction in signal transmission arising in the context with the chronic cerebrospinal venous insufficiency (CCSVI), a recent hypothesis related with MS pathophysiology. Subsequently, it insights brain-machine interface (BMI) as an alternative approach to improve the HRQoL of MS subjects. Information sources were searched from peer-reviewed data bases (Medline, BioMed Central, PubMed) and grey-literature databases for data published in 2000 or later. We also did systemic search in edited books, articles in seminar papers, reports extracted from newspapers and scientific magazines, articles accessed from internet; mostly using PubMed, Google search engine and Wikipedia. Out of approximately 178, 240 research articles obtained using selected keywords, those articles were included in the present study which addresses the latest definitions of HRQol and latest scientific and ethical developments in the research of MS and BMI. The article presented a brief survey of CCSVI mediated MS and BMI-approach as a treatment to serve the patients suffering from disabilities as a result of MS, followed by successful precedence of BMI approach. Apart from these, the major findings of selected research articles including the development of parameters to define HRQoL, types and development of BMIs and its role in interconnecting brain with actuators, along with CCSVI being a possible cause of MS have formed the foundations to conclude the findings of the present review article. We propose a perspective BMI approach and promises it holds for future research to improve HRQoL in MS patients. In addition, we propose that brain-computer interfaces will be the core of new treatment modalities in the future for MS disabilities.
