The purpose of this paper is to explore the contributing factors of the knowledge management in universities through literature research, extract three elements that is cultural factors, information technology factors and organizational factors as hypothesis. The assumption is examined and verified through factor analysis by questionnaires, the data were collected from real knowledge management system...
This paper proposes a parameterized algorithm for aligning two protein structures, in the case where one protein structure is represented by a contact map graph and the other by a contact map graph or a distance matrix. If the sequential order of alignment is not required, the time complexity is polynomial in the protein size and exponential with respect to two parameters and...
Accounting information system play a crucial role in enterprise information management, it is of great importance for modern enterprise management. In this paper, we focus on how to effectively assess and control risk of the accounting information system. Index system for accounting information system risk evaluation is proposed, which is made up of five parts: 1) U1: Technical risk, 2) U2: Operational...
With the wide application of ontology in the field of computer, ontology aroused people's concern. In order to conduct nubilous object, Fuzzy ontology is introduced. How to construct the fuzzy ontology becomes a meaningful work. It is known that the inaccuracy of information is high, which leads to inefficiency in the manual construction of fuzzy ontology. To solve this problem, conceptual distance...
Distributed Denial of Service (DDoS) attack presents the following characteristics, that the botnets become extra-large scale, the mode of attack presents a variety of characteristics and the application-level attacks become the main attack approach, which seriously impact on Internet Security. However, traditional software defense detection means have such problem, that the accurate rate is too low,...
The calibration of accelerometers and gyros error coefficients is an effective way to reduce navigation error of Ring Laser Gyroscope (RLG) Position and Orientation System (POS). To reduce the complexity of the traditional calibration method, an improved scheme of six-position hybrid calibration method in full temperature was proposed based on the error model in accelerometer and gyro channels of...
With the rapid development of smart grid, intelligent high-pressure equipment to be more concerned about the industry. Intelligent component for high-voltage equipment and smart grid construction of great significance. The starting point of the article is an intelligent equipment, considering the intelligent substation architecture and development. Put forward high-voltage equipment, the realization...
Alga microscopic image usually has a lot of noises and blurs. So a proper image enhancement algorithm which can remove noise and retain detail information is very important for alga microscopic image disposal. In the paper a new image enhancement method based on fuzzy set and subdivision is proposed. It is effective for alga microscopic image disposal. Subdivision scheme's good similarity among different...
Distribution, which is one of important part in the logistics system, has a great influence on the improvement of the whole logistics efficiency and reducing of cost. Nowadays, because the development of domestic logistics distribution is still at initial stage and distribution scheduling system is basically at artificial experience stage, it is unable to meet extensive centralized distribution, uniform...
As the most promising candidate for the realization of high-efficiency light sources for general lighting, the high power lighting emitting diodes(HP-LEDs) still have reliability issues that hinder the large scale application of LED devices. Nowadays, the reliability is becoming an essential barrier for LED devices to substitute the traditional light sources. Failure analysis is one of the key approaches...
With the development of sensor and measurement technology, more and more parameters are monitored to assess power transformer condition. Different parameters may reflect different aspects of transformer insulation and the same parameter diagnosed by different methods may get different results. Facing such a complex transformer system and so much online and offline data, the most important thing is...
[Purpose]Soil moisture is a main limiting factor to influence vegetation restoration in loess plateau. Studying the impact of environmental factors on spatial distribution of soil water resource from regional scale can make it easier to understand the relationship between vegetation restoration and eco-environment construction, which can provide theoretical basis about soil water resource effective...
High power light emitting diodes (LEDs) have begun to play an important role in many illumination applications due to their excellent performance in terms of high efficiency, low power consumption, high reliability and long life. With the rapid development of the LED industry, the reliability is becoming essential for the large scale applications of LED devices, modules and systems. Generally the...
In a single chamber microbial fuel cell (MFC), the gas diffusion electrode was employed as cathode. Different organic substrates including starch, glucose and drainage from a hotel were used as fuel to generate electricity. Glucose resulted the best electricity production and the highest COD removal ratio. Nickel foam and carbon cloth were employed as anodes and their effect on MFC performance was...
On behalf of The 2nd International Conference on Information Science and Engineering (ICISE2010), it is my great pleasure to welcome you to the conference. This annual international event has attracted a great number of academies, scientists, engineers, postgraduates and other professionals from a large range of countries. ICISE2010 will provide a unique forum to discuss a large array of Information...
In this paper, we propose a modified bidimensional empirical mode decomposition (BEMD) algorithm where the interpolation method is based on radial basis function interpolation using blocking technique combined with natural mosaicing. We can get ride of solving large linear equations and calculating huge matrix. It is proved that the modified method has faster calculating speed. At the same time, it...
As the traditional security and defense systems appear some defects, such as wiring problems, higher construction and maintenance expense and delay of receiving alarm messages, a scheme based on Internet of Things is proposed. Embedded ARM9 S3C2440A micro controller is adopted as system master controller, which carries out receiving and processing the transmission alarm message of RF chip worked at...
Tuning the hyperparameters of Support Vector Machine (SVM) is an important way to improve the generalization performance of SVM. Because it is time consuming to seek for optimal parameters by grid search method, the Ant Colony Optimization (ACO) search method selecting parameters is presented in my paper, which can acquire the best parameters of SVM.. My research was done in Xijieri area, Qinghai...
The spectral library of Shan Mei Litchi Orchard in Zeng Cheng City, which was built on the basis of the spectrum of the representative litchi and its background parameter measured by Analyzed Spectral Devices(0.35~2.5μm), was transformed into the spectral library of TM band width. The digital number of TM image, which had been preprocessed, was transformed into ground surface reflectance. The litchi...
In order to compress calculation, the background estimation algorithm for the infrared target detection was proposed. Firstly, a Least Square Matrix is proposed and an image background is estimated. Then the target is detected by self-adaptive threshold detection in different images. It is shown by nonlinear function regression experiment and sequence infrared image detection experiment whose methods...
