This paper describes a PC-based controller for robot-assisted minimally invasive surgery. The development is motivated by the need of reducing the exposure of operating room personnel to X-rays during surgical procedures such as percu-taneous discectomy. The approach taken consists of upgrading the hardware architecture and the control software of a clean-room PUMA 260 manipulator, and by devel...

Computing devices in pervasive environments have limitations on the following attributes: calculation capacity, power consumption, and chip size. The huge amount of operation required for applications of cryptographic primitives restricts the implementation of these primitives in pervasive environments. In order to overcome such limitations, we propose a new primitive for stream ciphers called ...

When developing embedded systems, developers often use simulation techniques to allow development to proceed without access to the target hardware. To make use of the high quality development tools available on the PC platform, one popular simulation method is to compile the code intended for the target system to run on the PC, allowing the development of the software to proceed on the PC witho...

Game AI is a well-established area of research. Classic strategy board games such as Chess and Go have been the subject of AI research for several decades, and more recently modern computer games have come to be seen as a valuable testbed for AI methods and technologies. Modern board games, in particular those known as German-Style Board Games or Eurogames, are an interesting mid-point between ...

background pancreatic cancer (pc) is classified as one of the most deadly cancers. since the role of diet in modifying the effects of known risk factors of pc has been well established, exploring the dietary intakes in relation to the etiology of pc can be useful for elucidating the mechanisms of the disease progression. methods and materials this study was conducted within the golestan prospec...

In this paper, we present the design and implementation of the integrated proactive surveillance system for prostate cancer (PASS-PC). The integrated PASS-PC is a multi-institutional web-based system aimed at collecting a variety of data on prostate cancer patients in a standardized and efficient way. The integrated PASS-PC was commissioned by the Prostate Cancer Foundation (PCF) and built thro...

When a group of characters in a game aim to efficiently explore an environment, it is important that they coordinate their actions to cooperatively discover new areas. This paper tackles the exploration task as a multiagent problem in the context of computer games. Four simple strategies and an auction-based negotiation strategy were implemented and evaluated. Their performance was compared in ...

This article investigates issues of controlling the amount of time during computer game play and potential solutions to help prevent excessive gaming. The study incorporates the realization of three different variants. Two screen based solutions and one based on a physical agent, outside the computer screen, provide notification and additionally even “intervention” to the user. The three realiz...

stractDespite the complexity of modern computer games and the wide range of different themes explored, there been only a few games that feature large chaotic groups of people, such as those found at riots or protests. The st popular, State of Emergency, features hundreds of individual people on the screen at any one time, however the ificial Intelligence (AI) that controls the rioting NPCs is f...

A system is proposed in which case-based reasoning principles are applied to the wayfinding problem for computer games. As case-based reasoning is thought to mimic aspects of human thinking, applying this methodology can provide more convincing non-player character behaviour. Additionally, knowledge re-use could provide performance gains through a reduction in redundant computation. Agents stor...
