Unmanned ground vehicles are one of the enlightening ideas that will shape our future by providing enhanced safety and improved mobility. Although the development of prototypes is still going on, we are now assisting to demonstrations that witness the real applicability of the early concepts. T HE history of Unmanned Ground Vehicles (UGVs) developed in the last 20-25 years. In fact, although th...

background there is significant prevalence of physical injuries sustained by civilian recruits at military training garrisons. civilian recruits sustain these injuries mostly during the intensive and rigorous military combat-training period. objectives we sought to determine the prevalence and causes of oral and maxillofacial injuries as the first step in reducing and preventing them in civilia...

The role of authoritative sources of information in a constructivist learning environment has always been ambiguous, especially in science learning where there is a bountiful of knowledge readily available in various sources. Taking a social semiotics perspective in this study, we take the view that authoritative sources are inscriptions of cultural artifacts and science learning involves meani...

In this paper, we present a methodology for finding authoritative researchers by analyzing academic Web sites. We show a case study in which we concentrate on a set of Czech computer science departments’ Web sites. We analyze the relations between them via hyperlinks and find the most important ones using several common ranking algorithms. We then examine the contents of the research papers pre...

Immunoassay interferences are diverse in scope (1–8) and are the subject of several recent large-scale studies (9, 10), opinions, and editorials (6, 11). Most interferences originate from components of the sample (e.g., human antianimal antibodies, lipid, bilirubin, drug metabolites) that interact with assay reagents or the detection system. The latest interference to rear its ugly head has bee...

The web resource is a rich collection of the dynamic information that are useful in various disciplines. There has also been much research work related to improving the quality of information searching in the web. However, most of the work is still inadequate to satisfy a diversified demand from users. In this paper, we exploit the hyperlinks in the web and propose a new approach called SFP in ...

We study dynamic selection of governments under different political institutions, with a special focus on institutional "flexibility" . A government consists of a subset of the individuals in the society. The competence level of the government in office determines collective utilities (e.g., by determining the amount and quality of public goods), and each individual derives additional utility f...
