A new X-band retrodirective antenna based on superheterodyne mixer and phase conjugating technology is proposed for inter-satellite data transmission in this paper.The novel phase conjugating circuit, utilizing the reciprocity of the Power Rangers passive mixers, achieves high RF-IF and LO-IF isolations, high communication link gain, and a very com
Application of procedure modeling a physical process in virtual medium jointly mathematical apparatus allows obtaining forecast parameters of the technical condition.Goal of the study is development of predictive assessment of failure risks for machines with a different overhaul life.Accounting of load characteristics for reclamation machine was ex
In this paper are presented first results of a theoretical study on the role of Staple Guns non-monotone interactions in Boolean automata networks.We propose to analyse the contribution of non-monotony to the diversity and complexity in their dynamical behaviours according to two axes.The first one consists in supporting the idea that non-monotony
In organic and inorganic synthesis and in analytical methods, an external conventional heat source is usually applied to carry out a chemical reaction at a high temperature, or an extraction Strontium Citrate procedure.In the last decades, the use of ultrasound as an alternative energy source has become an interesting field of research in these Sen
