This article describes the implementation in C# of a Client/Server pattern, and the design of an instant message application in LAN. It also included the discussion of the Socket mechanism, I/O streams with the implementation. The software features the core instant messaging core functions, video conference, and file transferring between peers. It is an effective service and also very suitable for...
This article mainly elaborates the method and the process which are using the object-oriented idea to develop the Ajax-based technology platform for the University Educational Management. This system realizes the management about the university's organizational structure, student information, teacher information, student performance, student curriculum, teaching program, information dissemination,...
The impacting dynamic stresses of automatic weapon's key elements(breech mechanism) are analyzed and studied in this paper. The distribution and magnitude of dynamic stresses of the breech mechanism have been obtained with LS-DYNA when they are impacted. The intensity of the breech mechanism has been checked. The obtained results in this paper are of significant importance for breech mechanism design.
This paper introduces the data structure and the key algorithm to develop the structure mode reader of RFC document and gives the tree structure of RFC document and its sample picture in structure mode after a full research of the RFC document format and the class and the function of MFC.
This study attempts to explore Chinese students' beliefs and attitude towards Computer Assisted language learning (CALL) and the difference in attitude and beliefs towards CALL between good language learners (GL) and poor language learners (PL). The author designed the questionnaire composed by two parts — CALL Belief and Information Input Channel and Load via computers and internet. 100 valid questionnaires...
This study attempts to explore Chinese students' beliefs and attitude towards Autonomous Language Learning (ALL) and ALL under Computer Assisted language learning (CALL) environment and the difference in attitude and beliefs towards ALL under CALL environment between good language learners (GL) and poor language learners (PL). The author designed the questionnaire composed by two parts — ALL Belief...
This research focuses on the flapping wing mechanism design for the micro air vehicle model. The paper starts with analysis the topological structure characteristics of Single-Crank Double-Rocker mechanism. Following the design procedure, all of the possible combinations of flapping mechanism which contains not more than 6 components were generated. The design procedure is based on Hong-Sen Yan's...
One-class SVM, which is a good machine learning method, has recently attracted wide interest. In this paper, we focus on the properties of the optimal solution to its primal optimization problem. We first prove that the optimal solution with respect to the normal vector of the hyperplane is unique, and then present and prove the necessary and sufficient conditions for the case where the optimal solution...
At present, each industry has its own database system. Yet, the overall performance of the business systems is falling, with the increase of running time and the rapid growth of the amount of data. Data rapid finding program was designed in this paper, table partition and index partition technology were used in large oracle table, and fast data retrieval was completed.
The advantages and shortcomings of three methods to find linear systematic error were analyzed. Malikov criterion is the most common method, but it often produced wrong judgment in application. The invalidation reason of Malikov criterion was analyzed, and then the t-test method was developed to find linear systematic error. The t-test method can exactly judge whether there is linear systematic error...
