Sensor array geometry has a direct impact on the direction-of-arrival (DOA) estimation of a seismic signal.In this paper, we design a planar array that aims to optimize the DOA estimation of a narrowband signal in the sense of the minimum mean-squared-periodic-error (MSPE) obtained by the maximum a-posteriori (MAP) estimator of the DOA.We investiga
Electromagnetic interference poses enormous challenges for feedback-controlled systems, especially at medium-voltage levels.As power converters are increasingly utilized for medium- and high-voltage applications, optically-based measurement methods must be explored.This paper investigates current measurement via electroluminescence from silicon car
Feeding is an elementary human need from which we obtain the energy and nutrients necessary for development and survival.Health heavily depends on food, which can be a means of knafs lander 3 different microbial hazards when contaminated at any stage of the food chain, compromising food safety and consumer health.Fish are considered widely produced
Chemical separation and purification are the important part of the chemical industry which consumes up to 70% energy cost.The separation technology such as distillation and absorption are well known in essential oil purification.The purification of clove leaf oil needs an attention because the current technology still consumes high energy and produ
