Ever since the invention of Bell Laboratories Layer Space-Time (BLAST) in mid 1990s, focus MIMO research and development has been largely on pushing limit spectral efficiency. While massive technologies laid foundation high spectrum efficiency 5G beyond, challenge remains improving energy given increasing complexity associated radio systems. With substantial negative implications climate change...
In this paper a novel power management method for an electric vehicle (EV) equipped with two energy storage systems is presented. In this way, an optimized nonlinear controller based on fuzzy system is developed. The main stage to design a fuzzy controller is proper determination of fuzzy rules and membership functions that in this paper, the fuzzy rules and input and output membership function...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Energy efficient lighting can be achieved by help of high efficiency light emitting diodes (LEDs). Substantial performance gains are feasible in the green – 500–555 nm – spectral region by implementing proper design of the active region. Here we analyze external quantum efficiency of high performing LED dies as a function of current and temperature in order to formulate relevant optimization ru...
It is believed that energy efficiency is an important constraint in brain evolution. As synaptic transmission dominates energy consumption, energy can be saved by ensuring that only a few synapses are active. It is therefore likely that the formation of sparse codes and sparse connectivity are fundamental objectives of synaptic plasticity. In this work we study how sparse connectivity can resul...
