technology advancement improves the way we interact with computer systems. keyboard, mouse, and touchpad provide an easier and more natural way of interaction with a computer system. nowadays, by introducing low cost and high performance depth cameras like kinect and xtion, new opportunities are available for creating even more natural interfaces. in this paper, a new model was demonstrated for...

introduction: users of hospital information system know its problems better than others. studying their views are very important and can be especially effective in the development of the information system. the aim of this study was to investigate the users' views towards the quality of hospital information system in the training hospitals of mashhad university of medical sciences. methods: the...

the early computer-aided design/computer-aided manufacturing (cad/cam) systems were relied exclusively on subtractive methods. in recent years, additive methods by employing rapid prototyping (rp) have progressed rapidly in various fields of dentistry as they have the potential to overcome known drawbacks of subtractive techniques such as fit problems. rp techniques have been exploited to build...

Abstract— In order to provide complete security in a computer system and to prevent intrusion, intrusion detection systems (IDS) are required to detect if an attacker crosses the firewall, antivirus, and other security devices. Data and options to deal with it. In this paper, we are trying to provide a model for combining types of attacks on public data using combined methods of genetic algorit...

This paper presents a discrete-time single-server finite buffer N threshold policy queue with renewal input and discreteMarkovian service process. The server terminates service whenever the system becomes empty, and recommencesservice as soon as the number of waiting customers in the queue is N. We obtain the system-length distributionsat pre-arrival and arbitrary epochs using the supplementary...
