Background: Computer usage has rapidly grown. This is because it helps to resolve problems, i.e., encountered in daily life by individuals. Various monitor screens that have been developed affect the userchr('39')s eyes. Screen size is one of the relevant impacts. Thus, this study compared the immediate effects of two computer screen sizes on visual fatigue in Video Display Terminal (VDT) users...

The localization accuracy of a track-before-detect search for a target moving across a distributed sensor field is examined in this paper. The localization accuracy of the search is defined in terms of the area of intersection of the spatial-temporal sensor coverage regions, as seen from the perspective of the target. The expected value and variance of this area are derived for sensors distribu...

Representation and reasoning about time-dependent information is an active and important research area in Artificial Intelligence and in Computer Science. Vilain and Kautz’s point algebra (see [VK86]) is one of the most influential models used for representing and reasoning with qualitative time information, because the reasoning tasks are solvable in polynomial time in that model, contrary to ...

Typical image feature trackers employ a detect-describe-associate (DDA) or detect-track (DT) paradigm. Intuitively, a hybrid of the two approaches inherits the benefits of each approach and possibly their defects, however this has never been demonstrated formally in a more general setting. In this paper, the stability and speed of DDA, DT, and hybrid trackers are compared and discussed using a ...

– The Internet is growing explosively, as is the number of crimes committed against or using computers. As a response to the growth of computer crime, the field of Computer and Network Forensics emerged. Computer forensics is the art of discovering and retrieving information about a crime in such a way to make it admissible in court. It is after-the-fact in that the only preventative capability...

Causal broadcasting has been introduced to reduce the asynchrony of communication channels inside groups of processes. It states that if two broadcast messages are causally related by the happened-before relation, these messages are delivered in their sending order to each process of the group. Even though protocols implementing causal broadcasting do not add control messages, they suuer from t...
