A variety of Software Sizing approaches have been conjectured in the literature. While many of these approaches have been used for Software Cost Estimation, none were specifically designed for Software Costing. This paper reviews current methods of Software Sizing to determine their suitability for Software Cost Estimation. The approach differs from previous approaches in that it is based on a ...

Creating useful software is a major activity of many scientists, including bioinformaticians. Nevertheless, software development in an academic setting is often unsystematic, which can lead to problems associated with maintenance and long-term availibility. Unfortunately, well-documented software development methodology is difficult to adopt, and technical measures that directly improve bioinfo...

Theories of interorganizational coordination propose that that the fit between information processing capabilities (structure, process and technology) and information processing needs (environmental, partnership and task uncertainty) is a strong determinant of IOS performance. Recently, electronic marketplaces have replaced many traditional interorganizational systems (IOS). While traditional I...

For years, the Human Computer Interaction (HCI) community has defined the expected characteristics of usable software systems. However, from a Software Engineering (SE) perspective, the process of incorporating usability into software is not always straightforward, as many usability features have strong implications in the underlying architecture. For example, successfully including a “cancel” ...

Different auction-based approaches have been used to allocate resources in Grids, but none of them provide the design choice for a specific economic model while considering the interest of all participants in the market. In this paper, we implement an auction-based framework for producer and consumer matchmaking in an ad-hoc Grid. In ad-hoc Grids, where the availability of resources and tasks i...

The ambiguity of natural language can be an important source of creative concepts. In compositional languages, a many-to-many network of associations exists linking concepts by the polysemy and synonymy of utterances. This network allows utterances to represent the combination of concepts, forming new and potentially interesting compound meanings. At the same time, new experiences of external a...

Let A = {a1, a2, . . . , as} and {b1, b2, . . . , bt} with s+r = n, the many to many point matching with demands and capacities matches each point ai ∈ A to at least αi and at most α ′ i points in B, and each point bj ∈ B to at least βj and at most β ′j points in A for all 1 ≤ i ≤ s and 1 ≤ j ≤ t. In this paper, we present an O(n) time and O(n) space algorithm for this problem.

Current efforts in Grid Computing operate on a zero settlement basis with users on the Internet downloading computation engines for “good causes” and subsequently returning their results. A number of attempts, for example Condor-G, GRaDS and NimrodG, have been made to develop computational economy based scheduling systems. However, these systems operate on a “top down” basis and have a number o...
