The paper investigates the theory of operation of a passive millimeter-wave seeker sensor using a fast electronic sequential-lobing technique and the experimental validation obtained through laboratory trials. The paper analyzes in detail the theoretical performance of a difference channel sensor and a pseudo-monopulse sensor deriving agile formulas for the estimation of target angular tracking...

This article is the fifth in a series of articles from our study examining information-seeking behavior in relation to information-retrieval (IR) interaction. This article focuses on the examination of the interaction variables within Saracevic’s (1989) triadic IR model. The analysis involved an examination of the information-searching behavior of academic researchers during a mediated interact...

This paper provides an empirical characterization of elicitation purposes related to search tasks during mediated information retrieval. During retrieval, a human search intermediary consults with an information seeker about their information problem, and then conducts a search on the elicited topic, both elicit information from each other during the mediated search process. Elicitations during...

One of the most important problem in target tracking is Line Of Sight (LOS) rate estimation for using from PN (proportional navigation) guidance law. This paper deals on estimation of position and LOS rates of target with respect to the pursuer from available noisy RF seeker and tracker measurements. Due to many important for exact estimation on tracking problems must target position and Line O...

An in-house developed computer program system Belief SEEKER, capable to generate belief networks and to convert them into respective sets of belief rules, was applied in mining the melanoma database. The obtained belief rules were compared with production rules generated by LERS system. It was found, that belief rules can be presumably treated as a generalization of standard IF...THEN rules.
