The AC servo motor control system based on traditional single chip microcomputer exists the following problems: slow processing speed, poor real-timing and low integration, etc. In order to resolve above problems, a position, speed and torque control scheme of the AC servo motor based on the STM32F103ZET6 micro-controller is proposed. The system structure and principle has been introduced in this...
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
The quality of biometric sample acquired from different acquisition devices is higher, then the reliability of recognition is higher. For the same biometric sample, recognition method is better, then the reliability of recognition is higher. So this paper proposed a multi-biometric recognition algorithm using biometric sample quality and recognition expert reliability (PSVM for short). First, obtains...
Silicon Avalanche-based p+nn+ Light Emitting Devices (SiAvLEDs) have been developed in a silicon 0.35 micron RF bi-polar process with emission intensities up to 200 nWμm-1. The spectral range is in the 600 nm to 850 nm wavelength region. The achieved emitted optical intensity is 100 fold better as compared with recent other published work for nearest related devices. Particularly, evidence has been...
A scientific, objective and comprehensive evaluation of the works of the customer service staffs is essential for improving the customer service ability and qualities, and especially for improving the satisfactory rate. In this paper, we propose a scientific and objective method for the comprehensive evaluation of the staffs of State Grid Customer Service Center which consists of two steps. In the...
A novel score normalization algorithm, named MF normalization, is presented. The MF normalization algorithm can consider the client and impostor score distributions, and the relationship of different expert score distributions simultaneously. The MF normalization will be of fewer parameters to estimate, and is easy to implement. The simulation results on XM2VTS multimodal database show that the proposed...
Hadoop and Storm are playing a significant role in Cloud Computing and either of them has its own applicable area. Cocktail is a new hybrid system that combines Hadoop and Storm into one single system, leveraging the functions of two computing frameworks. The design and implementation of Cocktail includes a SQL-like query language making the implementation of details transparent for users, an intelligent...
According to the digital revolution and the dramatically increasing number of TV channels on different satellites thus a massive content being broadcasted, a copyright and intellectual property infringement problem is occurring due to piracy and misuse of content, especially in developing countries. The abuse of content is leading to a significant money loss to content owners that may cause the collapse...
This paper presents an ultra-low-power design technique for CMOS low noise amplifiers. Parallel capacitance with input transistor Cgs is discussed for reducing gate induced noise and make it an effective way to implement low power LNA with small transistor size and moderate biasing condition. This technique is more effective for advanced process with high transition frequency. A low power LNA is implemented...
In this paper, we propose an image compression framework that integrates image decomposition technique with image inpainting to exploit visual redundancy in color images. An original image is first decomposed into geometry and texture using nonlinear filter decomposition model. Then, the geometry and texture image are compressed with edge-based inpainting and the standard JPEG respectively. At the...
On the basis of mechanism structure and the flash temperature theory, the instantaneous contact temperature rising principle of constantly no clearance precision steel ball transmission is studied and the formulas of relative sliding velocity, maximum contact stress, and friction coefficient are derived. Meantime, the mathematical model of instantaneous contact temperature rising of engagement pairs...
The weapon target assignment (WTA) problem is to find a proper assignment of weapons to the enemy's targets with the objective of minimizing the total expected survival value of the targets. The problem can be formulated as a nonlinear integer programming problem, and is proven to be NP-hard. In this paper, we focus on the case where the defense has multi-type weapons and the offense (the enemy) has...
Automatic train operation (ATO) system generally consists of the generation of recommended speed profile and the speed tracking strategy. It determines the tracked trajectory and the energy consumption of trains during the trip. Therefore, the optimization of recommended speed profile and the tracking strategy are regarded as two important means to achieve energy-efficient train operation between...
Coupled learning algorithm, in which the eigenvector and eigenvalue of a covariance matrix are estimated in coupled equations simultaneously, is a solution to the speed-stability problem that plagues most noncoupled learning rules. Möller has proposed a class of well-performed CPCA (coupled principal component analysis) algorithms, but it is a pity that only few of CMCA (coupled minor component analysis)...
This paper investigates the technique of network access switch between host-gigabit-Ethernet-switch and backup-gigabit-Ethernet-switch, and proposes an automatic, security, stable and high reliability switching method adopting high-frequency relays. The new method uses the following strategy. If the host-gigabit-Ethernet-switch works properly, the automatic network switcher is powered off, the automatic...
As the environment of battlefield is increasingly complex, single UAV(Unmanned Aerial Vehicle) has problem in reconnaissance mission, which needs cooperative reconnaissance of multi-UAV. However, the multi-UAV cooperative reconnaissance mission planning has trouble in searching the excellent solution, because of its large searching space but sparse solution space. Heuristic algorithm, which is widely...
Based on the text feature and syntatic structure of Tibetan, this theory mainly focuses on categorization of Tibetan through ensemble learning classified method. Combine KNN and Naive Bayesian to build a basic classifier on account of three character subsets over category of word character. And then take weighted calculation of basic classifier. For the last step, calculate the weight of basic classifier...
