International Journal of computer science Issues 2012年第1 1-3期9卷 395-400页

作者： subramanian, D. Venkata Geetha, Angelina Department Of Computer Science and Engineering B.S. Abdur Rahman University Chennai India

Knowledge sharing portals are the primary gateways for users to access all the information they need for their activity with adequate safety, security and in the b.s. quality. The usability of a Knowledge sharing Portal plays an important role in every organization and higher learning institutions, as it helps to increase the user satisfaction, reuse of knowledge assets, consistency of information and simplification of the maintenance process, regardless of the context, order or type of users. The primary goal of this paper is to propose a strategy for the ranking and rating of usability of the KM system. In this proposed work, we first describe the ways to design and develop the quality factors, using a multi-dimensional metric model for measuring usability along with other supporting factors. secondly we have shown the ways to apply the Weighted Average Mean (WAM) on the usability factor and other relevant factors for evaluation. Using the weights and values generated in the metric datab.s., the usability of the KM system can be ranked and rated both manually and automatically. © 2012 International Journal of computer science Issues.

作者： P. Kumaran R. shriram Department of Computer Science and Engineering B.S. Abdur Rahman University Chennai India

The advent of pervasive computing has thrown various challenges in resource management and optimization. services offered by the various platforms need to be composed together dynamically to offer the b.s. outcomes to the user. service composition in pervasive environments enables the users to utilize diverse services in the environment from heterogeneous service providers to solve complex queries. We present here a survey that classify the existing service composition model for pervasive environments in terms of interoperability, discoverability, adaptability, context awareness, Qos management, security, spontaneous management, and autonomous management. In this work, a dynamic parallel service composition b.s.d on community networks is introduced exhibiting the properties of quality of service, spontaneous management and contingency management. The middleware provides a model for real time service monitoring and adaptation. The prototype work is described along with a discussion of the results.

The objective of the work is to propose a Trusted Fault Tolerant (TFT) model incorporating user recovery features in mobile Ad Hoc networking using Location Aided Routing (LAR) protocol. The LAR protocol in mobile Ad Hoc network is challenged by a complicated interaction of contention, congestion and mobility. The fault model addressed here covers the link faults that occur in the packet transmission due to the high mobility of the nodes and the node congestion occurs when there is no capacity for the buffers at the nodes to hold the incoming packets. The location fault occurs when the node moves away from the source to an unreachable location after having received the packets. The implementation model focuses on nodes which do not actively participate in a network that are considered as selfish or misbehaving nodes. The performance of the model is improvised using location awareness feature and node trust levels b.s.d on which the recovery of the lost packets is achieved. © 2011 IEEE.

A mobile ad-hoc network (MANET) is a collection of mobile nodes communicating within a transmission range and it is a self-configuring network of mobile routers. The concept of caching frequently accessed data provides efficient communication among mobile nodes. The main objective is to avoid the stale data using invalidation policy b.s.d on TTL. In this paper we introduce an Enhanced Adaptive TTL (EATTL) algorithm in which each 1-hop distance node's to data cache node maintain a hash table for cache invalidation. Data item name is used as key and TTL used as its value. simulations are carried out in Ns-2 to evaluate the performance of the proposed scheme. The simulation results showed that EATTL algorithm can cut the query delay by a factor of 3 and double the throughput compared to the Adaptive TTL.

Cooperative relaying introduces spatial diversity through the creation of a virtual antenna array. The vast majority of the research in digital cooperative relaying assumes the modulation level used by both the source and relay to be the same. This assumption does not necessarily hold when adaptive modulation is implemented. In conventional selection combining, the branch with the highest sNR is chosen;we refer to this scheme as sNRb.s.d selection combining (sNR-sC). In this paper, we introduce bER-b.s.d selection combining (bER-sC), as an alternative to sNR-sC, to be used in cooperative communications when a relay may use a modulation level different than that of the source. We provide bER performance analysis for the sNR-sC and bER-sC schemes and show that bER-sC significantly outperforms sNRsC, without any increase in complexity. Moreover, we analytically quantify the gain achieved by using bER-sC over sNR-sC through asymptotic approximation. We note that bER-sC and sNR-sC schemes are identical when the received signals belong to the same modulation level. © 2009 IEEE.

GROUND WATER MONITORING AND REMEDIATION 1986年第2期6卷 126-128页

作者： GRAVENGAARD, Gb Gabrielle B. Gravengaard is a geologist in the Water Resources Division at Environmental Science and Engineering Inc. located in Gainesville Florida. Her specialities include hydrogeology and geology. She works with computer ground water modeling and ground water monitoring using state-of-the-art technology. She holds a B.S. in geology from the University of Florida.

Performing long-term pump tests, single-well aquifer tests and long-term ground water monitoring were, in the past, considered costly and labor-intensive tasks. However, because of recent advances in portable data acquisition systems, these field tests can be performed in a relatively cost-effective and efficient manner. Certain data acquisition systems (DAs) have unique options available. Recently developed and commonly used computers are the Envirolab®, the Paroscientific®, and the In-situ®. The use of implementing DAs in ground water field studies has proved to be successful when compared to the many disadvantages of performing those tasks manually. successful acquisition of aquifer characterization data using computerized methods is highly dependent on the implementation of proper field programming and operational procedures. In order to provide high qualify and meaningful data, the field operator must be familiar with proper equipment implementation and programming instructions. Once familiar with these procedures, the use of DAs in the field provides a cost-effective and efficient tool for aquifer testing.
