Minimum impact and immediacy of citations to physics open archives of arXiv.org: Science Citation Index based reports

The present work has calculated the minimum Open Archive Impact Factors and Open Archive Immediacy Index for the Physics Classes of arXiv.org as calculated for traditional journals in Journal Citation Reports of the Institute of Scientific Information using Science Citation Index without the citation by the classes itself. The calculated Impact Factors reveal that High-Energy Physics classes of arXiv.org (‘hep-th’, ‘hep-lat’, ‘hep-ex’, and ‘hep-ph’) have made more impact on the scientific community than any other classes except ‘nucl-ex’. The Impact Factors for the year 2003 are: ‘hep-th’ (0.999), ‘nucl-ex’ (0.806), ‘hep-lat’ (0.766), ‘hep-ex’ (0.73), ‘hep-ph’ (0.719), ‘nucl-th’ (0.338), ‘quant-ph’ (0.334), ‘cond-mat’ (0.313), ‘astro-ph’ (0.195), ‘math-ph’ (0.162), ‘physics’ (0.061), and ‘gr-qc’ (0.002). If the period for getting the citations to the open archive classes is considered one year as against two years for journal articles, the rank of the classes is the same. The immediacy of citing the Open Archives is also high for the High-Energy Physics classes. The Immediacy Indexes for the year 2003 are: ‘hep-ex’ (0.619), ‘hep-th’ (0.454), ‘hep-ph’ (0.44), ‘hep-lat’ (0.263), ‘nucl-ex’ (0.238), ‘quant-ph’ (0.202), ‘nucl-th’ (0.185), ‘cond-mat’ (0.168), ‘astro-ph’ (0.094), ‘math-ph’ (0.075), ‘physics’ (0.03), and ‘gr-qc’ (0.002). The impact is definitely much higher than what is concluded from the calculated factors because self-citations are not reckoned in the study. Use of web-tools like ‘Citebase’, ‘Citeseer’ etc. may strengthen the above argument

Co-citation Analysis: An Overview

This article gives an overview of co-citation analysis and its applications in tracking the linkages among the intellectual works and mapping the evolutionary structure of scientific disciplines. It also focuses on the features, interface, terminology used, merits and demerits of co-citation based online database applications

Effect of shape anisotropy on transport in a 2-dimensional computational model: Numerical simulations showing experimental features observed in biomembranes

We propose a 2-d computational model-system comprising a mixture of spheres and the objects of some other shapes, interacting via the Lennard-Jones potential. We propose a reliable and efficient numerical algorithm to obtain void statistics. The void distribution, in turn, determines the selective permeability across the system and bears a remarkable similarity with features reported in certain biological experiments.Comment: 1 tex file, 2 sty files and 5 figures.

A Proposed Approach to Detect Sybil Attack Using SBDM in Wireless Sensor Networks

Recent advances in wireless and electronic communications have allowed the implementation of low-cost multifunction sensors, low power consumption and low power consumption, and communicate in a few words. Smart and cheap sensors, connected to the network through wireless connections and distributed in large quantities, offer unprecedented opportunities to monitor and control homes, cities and the environment. In addition, the sensors connected to the network use a wide range of applications within the defense area, generating new functions for recognition and surveillance and various tactical applications. Sybil is one of the most terrible attacks is the cloning attack of nodes, in which the attacker captures the node and extracts its secret information, creates replicas and inserts other malicious behavior into the network. In this document, sink Based detection mechanism (SBDM) have been proposed to detect and mitigate this attack

SSOPS based Solution to Improve QoS in VANET

Vehicular Ad-hoc Networks (VANETs) is an emerging network technology derived from ad-hoc networks. This paper provides the state-of-the-art of VANETs and provides optimum proposal by improving Quality of Service (QoS.) Today, wireless systems are preferred over wired systems and these are gaining popularity as it provides wireless connectivity to the users irrespective of their geographic position, VANET is one of them. VANETs are installed to minimize the risk of road accidents and to improve passenger comfort by permitting the vehicles to exchange various types of data. In this paper, the Signal Strength based Optimum Path Selection (SSOPS) based solution on how to mitigate the QoS issues that exists while using the existing methods are discussed. Moreover, the solution has been tested using NS2 software using various parameters

A Proposal Approach for Enhanced Route Stability in MANET Using AODV Protocol

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth restricted wireless links. Since the nodes in topology are mobile, the network might change rapidly and unpredictably with time. Due to mobility of nodes in a network, the path stability is disturbed and hence the link breakage occurs. In this paper, an estimated time based stable routing methodology is proposed with the help of flowchart, which further will improve breakage of link and hence the lifetime of the network will increase considerably

A Novel Methodology for Route Stability Using AODV in MANET

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth restricted wireless links. Since the nodes in topology are mobile, the network might change rapidly and unpredictably with time. The network is decentralized; where all network activities including discovering the topology and delivering messages must be executed by the nodes themselves i.e. route discovering functionality will be incorporated into mobile nodes. But, due to mobility of nodes in a network, the path stability is disturbed and hence the link breakage occurs. In this research work, the signal strength is continuously measured till the node go out of range. Then, time is noticed and if time limit is below threshold value, then the path is not selected. On the other hand, if the value of time limit is above threshold, the path is selected and hence the less breakage occurs in that case
