The conjugation of High Performance Computing (HPC) and Grid paradigm with applications based on commercial software is one among the major challenges of today e-Infrastructures. Several research communities from either industry or academia need to run high parallel applications based on licensed

Previous studies of commercial software enterprises have employed industry-level analyses, or have focused on major players in the industry. There is, therefore, a dearth of in-depth research on small-to-medium software enterprises (SMSE). The need to understand the institutional contexts and firm-specific capabilities of such firms is important, as they account for over 90% of software enterpr...

This paper reports the findings of an investigation of children’s performance and attitude towards a paper based and computer based test. Twenty children, aged between 7 and 8 of mixed gender, participated in this study using a commercial software application. The children’s attitude towards the software was captured through the use of a smarty-o-meter to indicate their level of preference and ...

OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 ...

This paper is devoted to simulate the arc movement in the quenching chamber of the low-voltage circuit breaker. Based on a group of governing equations, a three-dimensional (3-D) arc model is built and solved by a modified commercial code. According to the simulated results, some phenomena such as a ‘bulge’ in front of the arc column, a tail in the rear of the arc column, arc shrinkage near the...

Discrete groups of isometries provide a rich class of groups for detailed study in an undergraduate course in abstract algebra. After developing some geometric tools, we illustrate several important ideas from group theory via symmetry groups. In particular, we consider conjugation, homomorphisms, normal and nonnormal subgroups, generators and relations, quotient groups and direct and semidirec...

Data produced by three dimensional MHD calculations are often difficult to visualize. Here we present a technique to view field lines of vector fields and one to display multiple isosurfaces of scalar fields. These methods do not rely on expensive commercial software and are general enough to be applied to other research sectors where visualization of 3D fields is important. Printed copies of t...

Hot forging of an Fe-Ni-Co alloy used for aeronautical purposes has been modeled using the commercial software ABAQUSTM/Explicit in order to obtain all the mechanical and thermal information to proceed with piercing and ring rolling. The material used is a 909 Incoloy type super alloy and it is used for the energy generation industry. Information of the constitutive behaviour of the alloy was i...
