A general mathematical model for generating tooth surfaces of helical noncircular gears is established. Two basic parameters and a first order differential equation characterize this model. The condition for determining the cusp of tooth surfaces is also presented. Transverse pressure angle and normal length are introduced to deal with the model. The different tooth surfaces could be generated logically...
The modeling of complex control system is usually based on the UML, thus the distributed control system is generally constructed by function block. This paper studies the modeling element: Function Block Adapter, which responsible for the connection of UML-RT capsule and IEC 61131 function block. By an application to a realistic manufacturing system, the author describes the concept, structure and...
As a multidisciplinary subject, biomedical textiles included various disciplines such as textile and biomedical engineering, design and modeling, mechanics, materials and fiber science, and so on. Thus, it is a challenge for the experiment teaching in biomedical textiles. This paper presented the current status of experimental curriculum and recommended several suggestions to improve not only the...
Safety-related system development is now standardized in some intimation standards such as IEC 61131, For safety-related industrial applications, we propose using Function Block concept to facilitate system specification and verification testing. Control loops are built from components taken from domain-specific function block libraries. Code inspection and testing are the two predominant quality...
A fast time acquisition method for PSK-2DSS systems is presented in this paper. By analyzing the structure characteristics of the two dimensional spread spectrum sequence, the redundant operations hidden in traditional time correlation method were found. Then, a novel two-stage acquisition method is proposed, aiming mainly at removing the reduplicate multiply operations in the correlation processing...
Aiming at how to reduce energy consumption and improve the node survival cycle in mobile P2P network, SRDBSM was proposed. It uses the transmission characteristics of spatial node to search the optimal node which is considered as next-hop node within the maximum effective transmission range. It's not only reduces next-hop number and communion time, but also improves the efficiency of resource discovery...
With the rapid development of the computer and applied technology, universities increasingly focus on cultivating non-computer science students' computer application skills. This paper analyzes the teaching status and problems of non-computer major in universities, then explore the way to improve the computer application skills of the non-computer science students from the improvement of teaching...
Usually consumers need to provide private information when using E-commerce service. While this special information is vulnerable to leak, resulting from Internet operators' deregulation or government's surveillance and the potential venture blocks the development of E-commerce. Basing on Internet consumers' concerns about privacy violation, this paper establishes a structural equation model of the...
High surface area activated carbon (AC) obtained by KOH activation was pulverized by ultrasonic air-jet pulverization equipment and the effect of particle size of AC on rate performance of electric double layer capacitors (ECs) was investigated by electrochemical impedance spectrometry using an equivalent circuit model based on a mixed kinetic and charge transfer control. The model parameters were...
According the low-temperature (Td) data of 60 years from 1950/1951 to 2009-2010 in Fujian Province, geographic information, olive planting area, cut rates of yield and the farmer's net income, the low-temperature frost risk division of olive plant is done based on GIS technology, expert grading method, mathematical statistics and so on. The mainly indexes include the four factors of hazard, exposure,...
By replacing conventional mechanical bearing of wind power generator with magnetic bearing, the friction loss can be reduced obviously and the efficiency of power generation can be improved. Bearing capacity of radial magnetic bearing (RMB) is determined through analyzing the radial loads of wind power generator, and upon this, the structure of radial magnetic bearing is designed. Then the electromagnetic...
As one of the candidates of cellular phone TV standard, the DAB-based CDMB adopts convolutional codes as its channel coding. In this article, we present a new sum-product decoding algorithm, where parity-check matrix is constructed under the circumstance that the sending encoder is unaltered or partially modified. It shows that our method obtain about 1dB gain higher than the traditional Viterbi algorithm...
Data warehouse course is a discipline that includes many subjects. There are theoretical teaching and practical teaching in this course. This paper introduces a new teaching method that is called an embedded teaching method. This method is applied to the data warehouse course successfully. Firstly, the ideas of this method are presented. Some associative knowledge in other courses is integrated to...
In this issue, the effect of toluene diisocyanate on the mice blood secrum was studied to discuss its mechanism of EOS infiltration and conglomeration, which was the emblematical character of vocational asthma. Effects of TDI on the mass concentrations of IL-4, IL-5 in mice serum and granulocyte-macrophage colony-stimulating factor was observed by double-antibody sandwich enzyme-linked immunosorbent...
To elucidate the metabolism of toluene diisocyanate (TDI) in mice testis and epididymis, the metabolism was studied in vivo. By using of HPLC, the linear range, recovery and metabolic constants in mice testis and epididymis were studied. As result, both the metabolism of TDI in the testis and the epididymis were matched to the first order dynamic equation, and the average recovery was more than 96%...
By analyzing traditional method of projection position, we present a location method based on the car edge examination and color information in this paper. The characters are divided up by the traditional methods, the template storehouse is made artificially; and the characters are distinguished. The experiment results show that: compare to the traditional method of projection, the localization method...
This paper presents a method of group decision-making based on CBR. This method involves two steps. Firstly, decision-making problems are expressed by cases and the decision tree is created via ID3 algorithm. Then each decision-maker's preference is incorporated via utility theory to attain group consistent preference; and on the basis of the group preference, the similar case is retrieved in the...
