Recognition of the role played by social capital in the way in which entrepreneurs access resources and information has grown in recent years. Social capital refers to „productive potential‟ which is derived from relationships between actors (Coleman, 1988). According to Nahapiet and Ghoshal (1998) social capital has three distinct dimensions: structural, relational and cognitive. While the str...

Instruction fetch bandwidth is feared to be a major limiting factor to the performance of future wide-issue aggressive superscalars. In this paper, we focus on Database applications running Decision Support workloads. We characterize the locality patterns of ia database kernel and find frequently executed paths. Using this information, we propose an algorithm to lay out the basic blocks for imp...

We describe the application of automated support for issue tracking and related software engineering activities of development teams at the world’s largest medical device manufacturer. We present some challenges and classes of defects found in product software, related artifacts, and the issues which track them. We describe enhanced means for defect detection, data mining and analysis, and othe...

As the issue rate and depth of pipelining of high performance Superscalar processors increase, the importance of an excellent b r a n c h predictor becomes more vital to delivering the potential performance of a wide-issue, deep pipelined microarchitecture. We propose a new dynamic branch predictor (Two-Level Adaptive Branch Prediction) that achieves substantially higher accuracy than any other...

Prepaid energy meters have been widely adopted by utilities in different countries across the world as an innovative solution to the problem of affordability and consumption management. However, the present smart card based systems have some inherent problems like added cost, low availability and lack of security. In the future Smart Grid paradigm, use of smart meters can completely overhaul th...

This paper presents the activities undertaken in TELEFONICA I+D under the SESMU project to define an integrated customer management functionality for multimedia services. The defined functionality includes customer queries, trouble ticketing, billing management, contract management, inventory control and marketing support for services like satellite digital television distribution, cable televi...

An electronic ticket is a contract, in digital format, between the user and the service provider, and reduces both economic costs and time in many services such as air travel industries or public transport. However, the electronic ticket security has to be strongly guaranteed, as well as the privacy of their users. We present an electronic ticketing system that considers these security requirem...

Code review is becoming a common practice in large scale software development projects. In the case of free, open source software projects, many of them are selecting Gerrit as the system to support the code review process. Therefore, the analysis of the information produced by Gerrit allows for the detailed tracking of the code review process in those projects. In this paper, we present an app...

Telecommunications networks comprise elements of very different types that work together to provide services. Quite often, hardware failures are interrelated and it is hard for technicians specialized in specific hardware to find out these relationships. In this context, Bayesian Networks (BN) provide a good and flexible solution because they allow us to model the causal relationships between e...

This study attempted to reuse the web learning portfolios to scaffold problem solving for activating students ’ Zone of Proximal Development. First, we analyzed cases from students ’ learning portfolios for getting case knowledge and student ability, and then used Case Based Reasoning technology for recommending cases to students. After students referred these cases, we adopted Data Mining tech...
