Background Trichoderma reesei is one of the most important fungi utilized for cellulase production. However, its cellulase system has been proven to be present in suboptimal ratio for deconstruction of lignocellulosic substrates. Although previous enzymatic optimization studies have acquired different types of in vitro synthetic mixtures for efficient lignocellulose hydrolysis, production of in vivo...
This paper presents a proposed cuckoo search algorithm with interactive learning and linear decreasing probability strategy (CSIL) to solve the economic dispatch problem with power balance, prohibited operating zones, valve point effect, and ramp rate. In the new approach, interactive learning strategy helps the nest to exchange good information from each other. Meanwhile, the linear decreasing probability...
In modern cognitive ratio systems, the spectrum is becoming increasingly crowded and expensive; thus spectrum sensing becomes more important than ever before. Traditional spectrum sensing assumes Gaussian noise (or of other given distributions) in general. However when secondary users (SUs) have no prior information about the measurement distributions, the spectrum sensing schemes assuming given distribution...
In this paper, we consider an overlay cognitive radio network that transmits discrete-time analog sources over additive white Gaussian noise channels. Our focus is on the case where the primary and secondary sources are correlated. The secondary user (SU) knows the primary message non-causally, and allocates part of its power for transmitting the primary message. We study a hybrid digital-analog coding...
To enable effective signal detection of human microwave, it is important to design high performance ultra-wideband wearable antenna. Due to its intrinsic complexity, antenna optimization is a nonlinear problem that is expensive to simulate and optimize. In this paper, we propose to optimize tapered slot antenna (TSA) with an improved particle swarm optimization (PSO) algorithm. Comparing to the state-of-the-art...
Food chemistry and analysis is a professional basic course closely combining theory with practice. The practical teaching of food chemistry and analysis is of great help to improvement of classroom teaching quality. However, there are a variety of problems in practical teaching. Based on years of teaching experience, the proposal of experimental course reform is mentioned. The effectual methods of...
In this paper, the jitter-induced noise is estimated in continuous-time quadrature bandpass sigma-delta modulator. The closedform formulas for the output spectrum of noise caused by clock jitter are derived. The correctness of the obtained analytical results is proved, based on model simulation. The noise introduced by clock jitter increases the in-band noise power, and therefore decreases the signal-to-noises...
Introducing the rank-weight method into the basic ant colony optimization (ACO), we use the modified ACO to optimize the weights and thresholds value of neural networks (NN). And when the BPNN is being trained, this method can solve the disadvantages of running into the minimum easily, and enhance the convergence speed. So we get a heuristic method, which is good at time efficiency and derivation...
