Changes in control ow, caused primarily by conditional branches, are a prime impediment to the performance of wide-issue superscalar processors. This paper investigates a block-level prediction scheme to mitigate the e ects of control ow changes caused by conditional branches. Instead of predicting the outcome of each conditional branch individually, this scheme predicts the target of a sequent...

With the increasing affordability of computers, displays and telecommunications, the scenario of introducing digital Information and Communication Technologies (ICT) into communities with little or no previous exposure to computing has become common place. Understanding how ICT affects the functioning of such communities is important for determining design and introduction strategies that can m...

Today mobile Internet, which is the “wireline and wireless (W&W)” environment, is a reality. Although broadband wireless technologies may replace the cable communication ones in the future, we have to work with the W&W framework for quite a while. The introduction of wireless communication in the Internet environment, broadband or not, has brought a new problem. That is, the traffic pattern can...

This paper focuses on reducing power in instruction cache by eliminating the fetching of instructions that are not needed from a cache line. We propose a mechanism that predicts which instructions are going to be used out of a cache line before that line is fetched into the instruction buffer. The average instruction cache power savings obtained by using our fetch predictor is 22% for SPEC95 be...

The paper primarily suggests the use of RFID technology to provide an efficient and enhanced automated ticketing system. The principle aim of the paper is to improve the efficiency of the prevailing suggested RFID ticketing system by considering and overcoming its limitations. The prevailing system proposes the installation of RFID reader circuit in each and every bus stop to facilitate the cal...

This paper addresses the problem of knowledge templates update in product development. A framework is developed to support template instances update process by providing a decision support system and an update strategy. An Issue-Based Information system is designed to allow the collaboration among various experts in order to solve template related problems. An ontology is used to represent and ...

This case study concerns the use of software agent advisors to improve efficiency and quality in issue tracking activities of development teams at the world’s largest medical device manufacturer. Each software agent monitors, interacts with, and learns from its environment and user, recognizing when and how to provide different kinds of advice and support to facilitate issue tracking activities...

A ~ s w ~ K The use of' wireless and mobile devices is espanding worldwide; with, a growing eagerness to find new and useful ways to apply mobile technologies. New applications, as mobile ticketing, can benefit of mobile-payment facility. This paper aims to provide a mobile ticketing system design for PDA, scalable to other mobile devices, presenting a wireless weaknesses overview and security ...

Permporometry IS a method by which the characterlstlcs of the mterconnectmg ‘active’ pores of an ultrafiltration membrane can be measured It 1s these ‘active’ pores that are responsible for the actual membrane performance Apphcatlon of permporometry on different membrane types, including ceramic as well as polymeric membranes, shows that the method can provide obJectwe mformatlon on the ‘active...

Electronic consultation through the Internet has become an important means of eparticipation in order to enable interaction and discussion among government agencies and citizens on public policies and decisions. Tools that enhance the quality of electronic consultations need therefore to be designed in a way that better opinions and arguments are produced. Well designed ICT tools can contribute...
