We analyze the intermediate buffer requirements in a tandem queue where service times of each customer are deterministically correlated between the servers and arbitrarily distributed between customers. The major issue at hand is the determination of intermediate buffer sizes assuring no blocking when the arrivals pattern is arbitrary and unpredictable. The analysis shows that the worst arrival...

Background. The Emergency Department (ED) is a daunting environment for the medical learner. Time pressures on the attending physicians mean that the learning needs of the medical student may, quite appropriately, be given a lower priority than the clinical needs of the patients. We propose that a collection of brief focused computer tutorials presented at the time of the patient encounter can ...

Evaluating progression of players in a game can take a variety of forms, but ideally combines playstyle or performance analysis with one or more aspects of progression, e.g. through a levelor mission-based structure. Furthermore, visualization of the results of analysis are essential to ensure that action can be taken on them. In this paper behavioral profiling through Archetype Analysis is com...

Small and medium size enterprises (SMEs) have gained competitive advantage by using Just-in-Time, Total Quality Management, and Information Technology. Cellular Manufacturing (CM) has received less attention from SMEs. This paper reports the findings of a case study of the application of Group Technology in an SME. A framework for the design and implementation of Cellular Manufacturing Systems ...

The increasing competition in global markets forces companies to optimise their manufacturing and logistic processes. Tied supply chains, just in time production are means to reduce costs while shortening the needed “time to market”. Customers are attracted not only by the product prize, but properties like quality and safety. In case of higher prized goods the ability to offer individualised p...

As knowledge becomes a crucial asset to organization’s survival, an efficient knowledge management policy should be set up and should result into an organizational memory. Similarly, an effective eLearning program must be implemented in the organization and exploit the organizational memory to manage competence evolution. In this paper, we introduce a framework to manage organizational knowledg...

BACKGROUND Human resolution for object size is typically determined by psychophysical methods that are based on conscious perception. In contrast, grasping of the same objects might be less conscious. It is suggested that grasping is mediated by mechanisms other than those mediating conscious perception. In this study, we compared the visual resolution for object size of the visuomotor and the ...
