Mobile Ad hoc networks (MANET) allow a set of wireless hosts to exchange information without any special infrastructure. The projct entitled “Energy Optimization in Manets using On-Demand Routing Protocol” motivates the need for energy management in ad hoc wireless networks. Limited battery power is one of the most important issues in mobile ad hoc network as the mobile nodes operate in limited...

Open Source Software Development appears to depart radically from conventional notions of software engineering. In particular, requirements for Open Source projects seem to be asserted rather than elicited. browser in attempt to understand how prevalent this phenomenon is. Using archives of mailing lists and issue tracking databases, these features were traced from first mention to release, to ...

We present a methodology for comprehensively evaluating architectural and technological alternatives of the processor, cache hierarchy, system interconnect, and main memory subsystems. We use the methodology to explore the design of an 8-way superscalar microprocessor implemented in 0.3 micron technology and employed in a high-performance workstation. We discuss the cache hierarchy design chall...

This paper studies value predictor design under table access latency and energy constraints for high-frequency, wide-issue microprocessors. Previous value prediction efforts make generous assumptions regarding table sizes and access conditions, while ignoring prediction latencies and energy issues. Our work shows that the latency of a high-performance value predictor cannot be completely hidden...

The wide deployment of wireless networks and mobile technologies and the significant increase in the number of mobile device users has created a very strong demand for emerging mobile commerce applications and services. Barcode-based identification and validation solutions are considered an important part of electronic commerce systems, particularly in electronic supply chain systems. This pape...

As we know that the online mining of streaming data is one of the most important issues in data mining. In this paper, we proposed an efficient one.frequent item sets over a transaction-sensitive sliding window), to mine the set of all frequent item sets in data streams with a transaction-sensitive sliding window. An effective bit-sequence representation of items is used in the proposed algorit...

In many real life queueing systems, customer balk from the queue but the environment is aware of it only at their times to be served. Naturally, the balking is an outcome of the queue length, and the decision is based on a threshold. Yet, the inspected queue length contains customers who balked In this work, we consider a Markovian queue with infinite capacity with homogeneous customers with re...

Continuing the Push for Cost Reductions The single most important issue in health care is eliminating unnecessary medical spending. Health costs have traditionally increased at 1% to 2% annually above the growth of the economy. Long-term financial security requires the growth in cost to slow to economic growth or less. With about one-third of medical spending estimated to be wasted, achieving l...

In this article the actual and relative costs of tuition at 3 Ontario medical schools are traced over the past 150 years. In addition, the factors that led to Ontario's nearly 4-decade experiment in private medical education (and to its eventual demise) are presented. In relative terms, tuition was stable for over a century, then declined (after 1960) as government support rose. Access to medic...

The W3C Linked Data Platform (LDP) specification defines a standard HTTP-based protocol for read/write Linked Data and provides the basis for application integration using Linked Data. This paper presents an LDP adapter for the Bugzilla issue tracker and demonstrates how to use the LDP protocol to expose a traditional application as a read/write Linked Data application. This approach provides a...
