In this paper we apply transformation optics theory to thermodynamics and design thermal cloaks and Neuw Rebel Skinny Eternal Black Jeans concentrators with arbitrarily shaped non-conformal objects and coatings.Expressions of the required material parameters are derived analytically and then validated by numerical simulations.We apply this method t
This paper propose a design and simulation of Amplitude Shift Keying (ASK ) 31 channel frequency hopping spread spectrum (FH/SS) transceiver system.The proposed design is implemented using Matlab/Simulink package.There are many available synchronization techniques that can be used in frequency hopping spread spectrum (FH/SS) transceiver system most
A 25-year-old woman with a history of recent dyspnea and palpitation was admitted to our center.Transthoracic echocardiography (TTE) showed an echogenic and septal muscular ridge along the left atrium which were indicative of cor triatriatum sinister (CTS).Further evaluation with transesophageal echocardiography (TEE) showed that a lower chamber of
Mining in close distance coal seams (CDCSs) is frequently associated with engineering disasters because of the complicated nature of stress distribution within CDCSs.In order to establish a layout of a roadway to minimize the occurrence of disasters associated with mining CDCS, here the spatial and temporal evolution of stress distribution during t
