Wireless sensor network (WSN) is one of the most evolving technologies. WSN involves collecting, processing, transferring and storing information about objects with the help of sensor nodes. Tracking and detection of targets is one of the most attractive applications of WSN in surveillance systems. To resolve the problem of target tracking, it is essential to deploy a system model. It has been observed...
The paper describes conceptual design, control strategies and full simulation for a new fully autonomous lower limb exoskeleton system for human motion enhancement. The exoskeleton supports the subject weight and provides an additional strength and endurance to the subject. The designed exoskeleton is able to decouple the weight/mass carrying function of the system from its forward motion function...
Energy efficient VLSIs with an ultra-low voltage power supply down to 0.5V are in growing demand in various applications, e.g., secure card, sensor node, and medical systems where power is supplied by RF wave, solar cells and small batteries. Various technological challenges, including PVT variations, low operating voltage margin, increased stand-by power consumption and low driving current, must...
The established building design process is a very conservative one. New technologies and energy efficient systems are hardly adopted since there are few reference buildings out there. Risk minimization, cost pressure and the complexity of the design process therefore leads to a poor innovation cycle and old-fashioned, inefficient buildings. We present a design flow that overcomes this hurdle by means...
Flux-switching machines are attracting interest among researchers over the last decade due to the increased importance of energy efficient systems. Among this class of machines, the rotary flux-switching PM machines (FSPM) with high power density are mostly analyzed by magnetic equivalent circuit (MEC) and finite element methods (FEM). In addition to those analysis techniques, this paper introduces...
This paper presents a very brief review on the energy loss development so far. There are lots of advancements in terms of generation, distribution, transmission and utilization. Also energy loss could also be reduced through training so the users know the limitation of the devices used.
