The thin walled metal plates (TWMP) on top of a commercial vehicle body are easy to produce vibration and booming noise under the action high-speed airflow, which reduces sound quality inside vehicle. Therefore, effective control TWMP is very important for comfort performance. Based experimental, finite element, dynamic fluid techniques, method identification, analysis optimization airflow proposed in this paper. problem frequency, source cause identified by amplitude-frequency...
Image enhancement techniques are very important to image processing, which used improve quality or extract the fine details in degraded images. In this paper, two novel objective functions based on normalized incomplete Beta transform function proposed evaluate effectiveness of grayscale and color enhancement, respectively. Using these functions, parameters estimated by quantum-behaved particle swarm optimization (QPSO). We also propose an improved QPSO with adaptive parameter control...
Abstract This article presents a comparison study of two unique parallel robotic machine tools (PRMTs): three degrees freedom (DOF) PRMT and 3-DOF with actuation redundancy. The has driving units linear motion, while the actuator redundancy four these units. For both designs, motion are identical machines have same passive constraining link in middle structure. manipulator is designed to prevent singularity improve stiffness. inverse kinematics Jacobian matrix PRMTs analysed. stiffness...
As a key technique of vibration control, transfer path analysis (TPA) provides theoretical support for diagnosis, analysis, evaluation, and optimization in mechanical systems. The coupling phenomena often exists the paths complex systems, which makes most existing TPA methods unable to accurately analyze function coupled paths. classical (CTPA) is an effective method solve problem coupling, but it changes inherent characteristics system, results can not reflect system. In order overcome...
Methane, ethane, ethylene, acetylene are the effective failure characteristic gases for power transformer. Semiconductor metal oxide gas sensor based on tin had been well applied in on-line monitoring of dissolved transformer oil. Nano-SnO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> was prepared by sol-gel method this paper. The microstructure and morphology o f sensitive materials were characterized X-ray diffraction (XRD) scanning...
A novel unidirectional authentication method is proposed to solve the problems of access security and protect privacy tag in RFID ecosystems on basis asymmetric cryptography. It provides better with shorter length secret key lower computational cost contrast other methods cryptographies. This implements one-way from reader-writer tag, allows update its private improve authentication. also own name, which can keep attackers tracking so as protection tags.
<title>Abstract</title> Vibration control is the key to development of high-speed and light-weight transmission system. There are many factors affecting vibration, influence misalignment most obvious. Therefore, it important understand dynamic response shaft with misalignment. In previous studies, researchers studied plane angle However, there few researches on effect spatial shafting vibration. this paper, a numerical model established. The vibration studied. experimental results show that...
In this paper, we explore the applicability of quantum-behaved particle swarm optimization (QPSO) algorithm, an efficient variant (PSO) to online system identification problems. First, quantum and are introduced. Then these two algorithms genetic applied identify parameters a described by differential equations respectively. Finally simulation results show that QPSO algorithm PSO greatly accelerate identification. Convergence speed accuracy far better than GA algorithm. Moreover convergence is PSO.
Top oil temperature is a key parameter of the transformer in operation, which difficult to measure and predict. To predict top more correctly, an artificial neural network (ANN) method was proposed. According field data from many transformers operation such as ambient temperature, bottom load current active power, prediction model based on Elman algorithm set up. In training section, nonlinear mapping relationships among power were determined, could be employed directly conduct with...

As events that results failure occur, triggered redetect original integral map pixel-wise confidence from color information. Furthermore, when quality unreliable no reliable re-detected, model not updated. Experiments...
