Background: A pressure ulcer is a complication related to the need for the care and treatment of primarily disabled and elderly people. With the decrease of the blood flow caused by the pressure loaded, ulcers are formed and the tissue will be wasted with the passage of time.Objective the aim of this study was to construct blood flow monitoring system on the heel tissue which was under external...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
In the 5th-generation mobile communication system (5G), a multiuser multiplexing scheme, nonorthogonal multiple access (NOMA), has been proposed to accommodate massive connectivity in wireless systems. By nonorthogonality, NOMA allows use of new domain that is ineffectively utilized conventional orthogonal (OMA) schemes. power-domain (PD-NOMA), user signals are allocated different power levels ...
To develop nanoscale sensors with future potential, a receiver utilizing the nanomechanical vibration of cantilever composed carbon nanotube, had been proposed for detecting digital information carried by wireless signals. The introduced includes two essential parts: phase detector and demodulator, which employ reference signal carrier signal, respectively. Additional components such as electri...
