Direction finder, an important component of electronic warfare system, is a device that detects electromagnetic waves radiated from target radar and measures its angle of arrival. Compared to the phase-comparison method, the amplitudecomparison method has simpler system, and it’s easy to miniaturize; however, relatively, its direction finding is less accurate, and it has various factors that oc...

A novel scheme is proposed for direction finding with uniform rectangular planar array. First, the characteristics of noncircular signals and Euler's formula are exploited to construct a new real-valued rectangular array data. Then, the rotational invariance relations for real-valued signal space are depicted in a new way. Finally the real-valued propagator method is utilized to estimate the pa...

conclusions the modified illinois change of direction test must be considered as an asymmetrical test because it underestimates more than half of the players’ agility performances. therefore, fitness coaches should take these results into account when using this test. results the analysis revealed no significant difference in time performance between the two versions of test as a within-subject...

High telomerase expression is a hallmark of most types of cancer, and, therefore, strategies to inhibit telomerase as an anticancer treatment have been pursuit for many years. In contrast to cancer, short telomeres and lack of telomerase are associated with aging and agerelated disease, including heart disease. Consequently, pharmacological telomerase activation can delay aging and also provide...

Dans le contexte de la catégorisation de documents, la sélection des descripteurs est une étape de pré-traitement importante qui permet non seulement de réduire la taille de l’index, mais aussi d’améliorer les performances des classifieurs. Parmi les approches utilisées pour construire un sous-ensemble de l’index, on peut distinguer d’une part, les méthodes de réduction de dimensions qui génère...

ACKNOWLEOOMENTS I wish to express my special gratitude to Professor Patrick Suppes, who formulated the problems I worked on, and whose advice, guidance and encouragement at all stages of this work was invaluable. I also want to thank the other members of the reading committee, Professor ~oravcsik and Professor Hintikka, whose criticisms and suggestions were extremely useful, George Huff, who ma...

In intelligent transportation systems (ITS), transportation infrastructure is complimented with information and communication technologies with the objectives of attaining improved passenger safety, reduced transportation time and fuel consumption and vehicle wear and tear. With the advent of modern communication and computational devices and inexpensive sensors it is possible to collect and pr...

In direction-of-arrival (DOA) estimation, the direction of a signal is usually assumed to be a point. If the direction of a signal is distributed due to some environmental phenomenon, however, DOA estimation methods based on the point source assumption may result in poor performance. In this paper, we consider DOA estimation when the signal sources are distributed. Parametric and nonparametric ...
