Nowadays, weblogs or blogs are important tools for personal or workgroup websites publication. These tools give the necessary performances to create, edit, evaluate, publish and file digital contents, in the framework of a standarized workflow, and for managing the digital information life cycle. Nevertheless, these tools must be complemented with existence of technical funcionalities necessary...

The permanent removal of data from computer disks has always been problematic. This has been due, in part, to the lack of availability of tools, and in part due to the misperception by the user that when a file is deleted it is destroyed and cannot be recovered and that when a disk is formatted, the data is destroyed. In this paper, we examine a number of the commonly available tools to determi...

A usability evaluation was performed on four drywall sanding tools and redesign specifications were developed for one, to improve the human-tool interface of the sander that provides the greatest control of drywall dust, a known respiratory health hazard. Sixteen novice participants performed simulated drywall-finishing tasks with each of the four tools: block, ventilated, pole, and wet sponge ...

Although the processing power of uniprocessor sys tems is signi cantly increasing every year there is a never ending quest for peak performance The so called grand challenges in computing require more computing power than a single uniprocessor machine can ever o er Recent advances in parallel processing however has brought the solution of grand challenges into reach What is usually neglected wh...

The purpose of this article is to provide a critical commentary of the physiological and psychological tools used in the evaluation of swimmers. The first-level evaluation should be the competitive performance itself, since it is at this juncture that all elements interplay and provide the 'highest form' of assessment. Competition video analysis of major swimming events has progressed to the po...

This paper presents an evaluation of feature modeling tools. The purpose of the evaluation was to gain insight in the aspects that influence the quality and more in the particular usability. The evaluation focused on the quality criteria: usability, safety, and the support for functional usability requirements. The study involved 9 feature-modeling tools and was done using an experimental evalu...

In the current state of the art in ontology matching, diverse golden standards are used to evaluate the algorithms. In this paper we show that by following appropriate rules in their construction and use, the quality of the evaluations can be significantly improved, particularly in the accuracy of the precision and recall measures obtained.

The emergence of large repositories of web-based learning resources has increased the need for valid and usable evaluation tools. This paper reviews current approaches to learning object evaluation and introduces eLera, a set of web-based tools we have developed for communities of teachers, learners, instructional designers and developers. Compatible with current metadata standards, eLera provi...

This chapter discusses a set of coordination tools (the Continuous Coordination (CC) tool suite that includes Ariadne, Workspace Activity Viewer (WAV), Lighthouse, Palantír, and YANCEES) and details of our evaluation framework for these tools. Specifically, we discuss how we assessed the usefulness and the usability of these tools within the context of a predefined evaluation framework called D...

A number of operational and geometric factors impact the safety of at-grade intersections. Examples include the type of traffic control, the existence of left-turn lanes, and adequate sight distance. Determining whether an intersection of particular geometric design has unusual crash patterns could help identify those locations that need additional safety evaluation. During the last two years, ...
