In adaptive learning systems for distance learning attention is focused on adjusting the learning material to the needs of the individual. Adaptive tests adjust to the current level of knowledge of the examinee and is specific for their needs, thus it is much better at evaluating the knowledge of each individual. The basic goal of adaptive computer tests is to ensure the examinee questions that are...
The aim of the presented work is to improve the quality of testing of SoC digital cores surrounded with test wrappers. The paper presents a new effective delay fault test generation method for the transition faults based on the skewed-load test. The generated delay fault test can be applied to a SoC core through a test wrapper architecture with only a simple boundary scan chain. This eliminates the...
This paper introduce the technology of electromotor control and protective electrical appliance intelligent, using the artificial fish swarm algorithm (AFSA) which is based on genetic algorithm to optimize the calculate of the intelligent ac contactor. According to the result of optimization design, we have made a showpiece, after the test and experimentation of the prototype; finally we got results...
The multi-core technique will play an important role in high density computing, therefore, it is significant to design MPSoC with handy intellectual property core. This paper gives the design of the 4-core multi-processor system on chip (MPSoC) based on hierarchy AHB bus architecture in RTL, and the testing results indicate that the speed increases along with the increasing dimension of the multiplication...
According to biological immune danger theory, a condition monitoring algorithm based on immune danger theory was presented. In the algorithm, the whole diagnosis feature space is divided into danger feature space, normal feature space and abnormal feature space. The algorithm consists of primary testing module, APC testing module and self-adapting testing module. The algorithm can make judgment according...
This paper proposed a system solution to data transfer and control based on EZ-USB 2.0 for FPGA applications. The data transfer is achieved in Slave FIFO mode of EZ-USB, and the FPGA controlling is realized by PC sending commands to 8051 in EZ-USB FX2 through EP.0 followed by 8051 sending the received commands to FPGA through I2C channel. The proposed solution offers a high-speed data communication...
DDoS attack is a major Internet security problem-DoS is that lots of clients simultaneously send service requests to certain server on the internet such that this server is too busy to provide normal services for others. Attackers using legitimate packets and often changing package information, so that traditional detection methods based on feature descriptions is difficult to detect it. This paper...
One of oldest and best-known methods used in constructive testing of smaller programs is the symbolic program execution. It is partly similar to method of simulation of computer function, but differs in aim. One of ways to prove whether given program is written correctly is to execute it symbolically. Aim of this paper is to test ramified program structure using single symbolic set of inputs, in one...
A new multi-channel virtual ultrasonic testing system which consists of PC cards, focus probes and machine system is proposed. Using this system the A, B, C scan, data processing and quantitative analysis can be realized. In addition, computer technology, virtual instrument, signal and image process technology are introduced to ultrasonic nondestructive testing and the range of application of traditional...
Aiming to increase the proportion of the samples that has been determinate classified in Naive Credal Classifier, this paper improves conservative inference rule and proposes an incomplete data classification model based on relaxed conservative inference rule. Simulation results of comparative experiment with Naive Bayesian Classifier and Naive Credal Classifier verify the effectiveness of this classification...
For the ground performance testing problem of airship propeller propulsion system, based on the operational principle of test method and the key technologies of the ground propulsion systems, a design of on-line testing system is proposed by high power-density asynchronous motor driven. This testing system can improve the measurement accuracy and efficiency. In this paper, the technological scheme,...
How will information from online banks influence the choice of customers? This research uses information processing theory, WOM theory, perceived risk theory and trust theory, in order to find the flow of information from online banks to customers, and the relationships among those issues. Moreover, online banks in Mainland China are the targets of this research.
A single-chip microcomputer-based test device of flash relay is presented in this paper, whose circuit and testing method are also introduced. The test device can not only detect parameters of relays in dynamic process, but also has additional functions such as durability detection, failure indication and so on. Finally, a simulated load circuit aiming at improving the test environment is designed,...
The purpose of this study was to identify switching costs and examine the moderating effect of switching costs on buyer loyalty model in the B2B e-marketplace. Then a questionnaire was constructed and data were collected from 649 buyers of a Chinese B2B e-marketplace in 114 countries all over the world. Multi-group analysis was applied to examine the moderating effect of switching costs. Finally,...

The text posed a brand new counting method of using infrared which was distinct to the normal usage in the product line. By adopting the infrared lattice and the appropriate recognition algrithom, the MCU is able to detect the status of traffic flow in complicated circumstance, easily and economically. All this enables to improve the real time information of traffic condition, furthter to instruct...
After subjects take part in the Mongolian Standard Speech Test, they have some divergent opinions about their tested results. In order to eliminate these divergences of the test results, a new window is opened to employ a kind of software to assist the testing of the Mongolian Standard Speech based on the comparisons of language features. Specifically speaking, after the subject's speech data are...
A new cross flow solid-liquid separate equipment with high efficiency has been proposed, and comparative experiment investigations between the municipal sewage plant and the test device of the separator and the numerical simulation of the device flow field using FLUENT CFD software have been combined to define its basic operating parameters and precipitation characteristics, and has laid the foundation...
This research examines the impact of perceived social environment on entrepreneurial intention based on the mediating role of entrepreneurial self-efficacy (ESE) in the context of China. Our results indicated that perceived social environment have positive impact on students' entrepreneurial intention and the impact among two specific role of perceived environment is different. Inspiration has the...
