In this expository article we will be primarily concerned with core aspects of Grids and Grid computing using OSS with some emphasis on utility computing. It is based on a technical report entitled 'Grid-Computing Using Linux' by the present author. Grids have made great progress in the area of scientific computing and collaboration projects in the recent past. They have also moved into the dom...

After telecommunications, also medicine has been revolutionized by optical fibers. They were firstly used, in the early sixties, to visualize internal anatomical sites by illuminating endoscopes. The essential technological solution to obtain good quality images was the introduction of “cladding” during the fifties. The result was the development of minimally invasive tools that have become ess...

Dr. George Lush Foss who died on 11th February 1985 at the age of 76 years was not only a highly respected General Practitioner in Bristol but also a pioneer in the early days of Endocrinology and the problems of sub-fertility. Educated at Marlborough and Jesus College, Cambridge he did his clinical training in Bristol where his father was a general practitioner in St. George. On the very day t...

"Blind source separation" is an array processing problem without a priori information (no array manifold). This model can be identified resorting to 4th-order cumulants only via the concept of 4th-order signal subspace (FOSS) which is defined as a matrix space. This idea leads to a "Blind MUSIC" approach where identification is achieved by looking for the (approximate) intersections between the...

For a computer science course of distributed computing, Internet is, at the same time, an object for study, and a (virtual) library of resources (textbooks, tutorials, FAQs, software packages (especially FOSS), project examples. But especially, a place for experiments with grid, cluster, and distributed computing tasks, i.e. a virtual laboratory for High Performance Computing. In the paper, som...

Because of the distributed and collaborative nature of free / open source software (FOSS) projects, the development effort invested in a project is usually unknown, even after the software has been released. However, this information is becoming of major interest, especially —but not only— because of the growth in the number of companies for which FOSS has become relevant for their business str...

The work presented in this paper is motivated by the need to estimate the security effort of consuming Free and Open Source Software (FOSS) components within a proprietary software supply chain of a large European software vendor. To this extent we have identified three different cost models: centralized (the company checks each component and propagates changes to the different product groups),...

Online learning in K-12 and higher education has been growing rapidly, and open source software has the potential to improve the quality of e-learning. This chapter describes how FOSS enables turning e-learning from a potentially restrictive and narrow framing of the education experience to an emergent and social experience. The chapter will identify several key elements of the FOSS model that ...
