Interference is one of the critical factors that affects the performance of cognitive radio networks. In these networks, secondary users are allowed to use the primary user channel with the condition that they cause no interference to it. Interference power received at the primary user is impacted by a number of parameters, including nodes transmit powers, distance between the primary user and the...
In this work, we studied the catalytic kinetics of the alliin/alliinase system using a fiber-optic in situ monitoring system (fiber-optic drug dissolution test system, FODT) to explore the application of a fiber-optic sensor analysis technique in the process of monitoring catalytic kinetics. According to Lambert–Beer's law and with the assistance of the computational relationship of alliin, allicin...
In order to meet the marketing demands, the core enterprise need to identify the bottleneck link of supply ability in the supply chain network, which can guide a prevention or improvement measure. In fact, the supply ability of a supplier usually is a variety. This paper takes genetic algorithm to identify the bottleneck of the supply chain network, and then simulates the supply chain network with...
There are big ripples on current and flux linkage and electromagnet torque under traditional direct torque control (DTC) on motor drive system. To solve these problems, fuzzy controller is designed to instead traditional hysteretic comparator, and zero voltage vectors are used to further reduce ripples. Rotor speed is estimated online by extended Kalman filter (EKF) algorithm. Speed sensorless DTC...
