This paper proposes a pre-reckoning algorithm for distributed virtual environments. First, an overview of dead reckoning techniques used in distributed virtual environments is provided. The benefits and drawbacks of implementing dead reckoning within specific types of distributed virtual environments are discussed. An alternative to traditional dead reckoning techniques used in DIS-compliant di...

Channels of communication are presented as an emergent property of cooperative work. During actual interaction channels of communication are typically used in an intermittent fashion. Thus bandwidth is not an appropriate measure. Instead pace, the measure of the rate at which individual communications occur through a channel, is proposed as a primary property. We can relate this to the pace of ...

This tool paper discusses how model behavior expressed in a UML and OCL model can be analysed with filmstrips and classifying terms in the tool USE. Classifying terms are a means for systematic construction of test cases. In the case of behavior models these test cases correspond to testing the model with different sequence diagrams. We explain how behavior analysis can be carried out in the to...

INTRODUCTION In developed countries, substituting physicians with nurse practitioners, physician assistants and nurses (physician substitution) occurs in nursing homes as an answer to the challenges related to the ageing population and the shortage of staff, as well as to guarantee the quality of nursing home care. However, there is great diversity in how physician substitution in nursing homes...

Healthcare professionals are dedicated to maintaining the confidentiality of patient information but are resistant to maintaining an information security compliant environment within a health information system. In this paper, a literature review is used to gain knowledge about the factors that affect this information security compliance. An overview of the security threats and those specific t...

Given a prediction of opponent behavior in a generalsum two-player normal form game, it is difficult to select a strategy that balances the opportunity to use the prediction to inform one’s action with the risk of becoming predictable. We propose Restricted Stackelberg Response with Safety (RSRS), a novel way of generating such a strategy. RSRS uses an r-safe Stackelberg equilibrium in a modifi...

Does past performance influence success in grant applications? In this study we test whether the grant allocation decisions of the Netherlands Research Council for the Economic and Social Sciences correlate with the past performances of the applicants in terms of publications and citations, and with the results of the peer review process organized by the Council. We show that the Council is suc...

This paper studies Knowledge Discovery (KD) using Tabu Search and Hill Climbing within Case-Based Reasoning (CBR) as a hyper-heuristic method for course timetabling problems. The aim of the hyper-heuristic is to choose the best heuristic(s) for given timetabling problems according to the knowledge stored in the case base. KD in CBR is a 2-stage iterative process on both case representation and ...

Destination choice modelling can be employed to analyse the choices that tourists make when selecting between different holiday destinations. The data for a destination choice modelling analysis are often obtained from a survey in which prospective tourists state their choices in a series of hypothetical choice scenarios. In each scenario, the choice alternatives are described in terms of desti...
