Abstract. Business value attainment should be a key consideration when designing software processes. Ideally they are structured to meet organizational business goals, but it is usually difficult to integrate the process and business perspectives quantitatively. This research uses modeling and simulation to assess process tradeoffs for business case analysis. A model for commercial software ent...

Open source software is increasingly used by public administrations as an alternative to commercial software. In this paper we present a case study of the transition of the ministerial cabinets of the Brussels-Capital Region towards OpenOfRce.org. In this case, the decision to use open source software was taken by the Government of the Brussels-Capital Region. The goal of the paper is to outlin...

With more emphasis on reuse of software applications, the commercial-off-the-shelf (COTS) based software systems have emerged. As a result, reliability analysis of COTS-based software system has gained prominence. The focus of this paper is to provide an overview for the state of the art of COTS-based software system reliability analysis. In this paper, we first describe the definition of COTS ...

This paper describes a method for mapping a sequence of notes to a set of guitar fretboard positions (tablature). The method uses a Genetic Algorithm (GA) to find playable tablature through the use of a fitness function that assesses the playability of a given set of fretboard positions. Tests of the algorithm on a variety of compositions demonstrate an excellent ability of the GA to discover e...

The increasingly popular design technique called ‘personas’ provides a natural way to introduce issues of diversity and power relationships in software development. Persona development is a powerful technique that must be used carefully. It may be the most effective way to introduce participative approaches into mass market software development. This is of broader significance because it is inc...

While quality has been widely stressed in literature as a goal of the software design methodologies, quality as a result of the interaction among the actors involved in the design and development processes has not received the same attention. This work aims to investigate the software production process by addressing the communication among work groups in the organisation. Our focus is on under...

In this paper a new bucket configuration for a Savonius wind generator is proposed. Numerical analyses are performed to estimate the performances of the proposed configuration by means of the commercial code COMSOL Multiphysicsr with respect to Savonius wind turbine with overlap only. Parametric analyses are performed, for a fixed overlap ratio, by varying the slot position; the results show th...

Many of the concepts that need to be taught in software engineering courses are hard to get across because it is difficult to give the student practical experience of the intuitions and techniques involved. The student must come to understand multiple design and implementation formalisms whose relationship is often hidden by modern commercial software. Education theory would suggest that studen...

I study the time series dynamics of commercial mortgage credit risk and the unobservable systematic risk factors underlying those dynamics. A first-passage model with equilibrium macroeconomic dynamics is presented, and the default hazard rate is solved. The solutions are then put into a state space form and estimated with real world commercial mortgage performance data using extended Kalman fi...
