Petascale data management and analysis remain one of the main unresolved challenges in today's computing. The 6 th Extremely Large Databases workshop was convened alongside the XLDB conference to discuss the challenges in the health care, biology, and natural resources communities. The role of cloud computing, the dominance of file-based solutions in science applications, in-situ and predictive...

In commercial software vendor organizations, evolution of a software product by means of scheduled feature releases is a central activity. Relying on existing work on maintenance task effort prediction, this paper proposes a management framework for periodically capturing updated estimation data and using it as a basis for initial planning and subsequent re-planning of releases. The framework i...

In this article, we extend Cheng, Zhang and Wang [17] model studied pricing strategies in marketing. The objective is to find the optimal inventory and pricing strategies maximizing the net present value of total profit over the infinite horizon. It is important to control and maintain the inventories of deteriorating items for the modern corporation. We will discuss two models: one is without ...

This paper is concerned with the economic trade-offs associated with open-sourcing, the business strategy of releasing free open-source versions of commercial software products. The effect of the release of open-source versions on the customers’ perception of products is an important determinant of open-sourcing outcomes. We model open-sourcing as a strategic option for firms that compete in th...

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...
