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...

اجريت هذه الدراسة في معمل الحشرات قسم وقاية النبات، كلية الزراعة ، جامعة عمر المختار، البيضاء – ليبيا، عرفت الحشرة قيد Ocnogyna loewii Zeller 1846 تحت فصيلة Arctiinae Arctiidae رتبة Lepidoptera وصفت الأطوار غير الكاملة (الطور اليرقي و طور العذراء) من ذكور واناث وتم اعتماد الوصف على الشكل الظاهري((الخارجي)) لأطوار طول الجسم وشكل قرن الاستشعار لون الأجنحة وكذلك الصفات والظاهري الجناح بالإضافة إلى...

This work presents an alternative approach (Evolutionary Algorithms approach) to traditional treatment of Recommender Systems (RSs). The work examines genetic algorithms possibilities to offer adaptive characteristics to this systems trough learning. The main goal, in addition to give a general view about RSs capabilities and possibilities, it is to provide an example mechanism for to extend RS...

Determination of mobile localization with time of arrival (TOA) signal is a requirement in cellular mobile communication. In some of the previous methods, localization with non-line-of-sight (NLOS) paths can lead to large position error. Also for simplicity, in most simulations suppose non stationary actual environments as stationary. This paper proposes (residual test + recursive least square)...
