Performance comparison of functional Magnetic Resonance Imaging (fMRI) software tools is a very difficult task. In this paper, a framework for comparison of fMRI analysis results obtained with different software packages is proposed. An objective evaluation is possible only after pre-processing steps that normalize input data in a standard domain. Segmentation and registration algorithms are im...

As the use of web grows, organizations are increasingly choosing to use it to provide their services. The modeling process is a previous step in the systematization of a process. Due to the great number of modeling tools in existence, it is necessary to identify the information that tools allow to specify. A set of concepts is proposed to evaluate modeling tools using three levels of abstractio...

In a given organization, if managers want to verify/improve the success and the return of investments of the organization Web site, they should assess the site quality during its entire life-cycle. Unfortunately, the trustworthiness of Web Quality Inspection Tools, which can be used to this aim, is not discussed in literature. The paper faces this problem proposing a thorough evaluation of trus...

Ontologies are being used nowadays in many areas, including bioinformatics. To assist users in developing and maintaining ontologies a number of tools have been developed. In this paper we compare four such tools, Protégé-2000, Chimaera, DAG-Edit and OilEd. As test ontologies we have used ontologies from the Gene Ontology Consortium. No system is preferred in all situations, but each system has...

Recently a great number of methods and frameworks to develop multiagent systems have appeared. Nowadays there is no established framework to evaluate environments to develop multiagent systems (MAS) and choosing between one framework or another is a difficult task. The main contributions of this paper are: (1) a brief analysis of the state of the art in the evaluation of MAS engineering; (2) a ...

Remote laboratories have become increasingly popular in engineering education, gradually replacing traditional hands-on labs. However, in the specialized field of microelectronics fabrication the move towards remote labs has been slow. This is due to the nature of the fabrication facilities, the cost and the extra challenges involved in such transformation. There has been wide debate regarding ...

We describe a number of experiments carried out to address the problem of creating summaries from multiple sources in multiple languages. A centroid-based sentence extraction system has been developed which decides the content of the summary using texts in different languages and uses sentences from English sources alone to create the final output. We describe the evaluation of the system in th...

This paper describes the performance evaluation and analysis of a set of open source petascale quantum simulation tools for nanotechnology applications. The tools of interest are based on the existing realspace multigrid (RMG) method. In this work we take a reference set of these tools and evaluate their performance with the help of performance evaluation libraries and tools such as TAU and PAP...

Despite their potential applications in software comprehension, it appears that dynamic visualisation tools are seldom used outside the research laboratory. This paper presents an empirical evaluation of five dynamic visualisation tools AVID, Jinsight, jRMTool, Together ControlCenter diagrams and Together ControlCenter debugger. The tools were evaluated on a number of general software comprehen...
