Efficient localization of multiple targets is one of the basic technical problems in wireless sensor networks (WSN).The traditional sparse representation method based on greedy class is not efficient in multi-target positioning.Aiming at this problem, a multi-target localization algorithm based on QR Course a pied - Femme - Chaussures - Neutre deco

The investigation into a full-scale 27 m high, by 6 m wide, thermosyphon loop.The simulation model is based on a one-dimensional axially-symmetrical control volume Combs approach, where the loop is divided into a series of discreet control volumes.The three conservation equations, namely, mass, momentum and energy, were applied to these control vol

Abstract: Difficulties and errors in the pronunciation of Arabic phonology still often occur in the process of learning Arabic by non-Arab students it is due to lack of attention in teaching Arabic phonology by teachers and non-Arab students.But in previous studies, no one has researched the use of Knee Pads methods in the learning.Thus in this stu

Low critical rotary speed and large vibration in the metal drive-line system of heavy-duty machine tool affect the machining precision seriously.Replacing metal drive-line with the CFRP drive-line can effectively solve this problem.Based on the composite laminated theory and the transfer matrix method (TMM), this paper puts forward a modified TMM t

In order to explore the influence mechanism of the perceived overqualification of the new generation of miners on safety performance and improve the safety performance level of the new generation of miners, based on the theory of relative exploitation, self-verification theory and social exchange theory, we construct a hypothetical model of the rel
