Design and Implementation of the School Status Management System for a University

近年来，随着某高校招生规模不断扩大，高校管理理念和管理方式受到极大的挑战，原有的传统管理模式和学习生活方法在当今快速发展的校园环境下显得极为不协调。在这其中，学生的学籍管理也变得越来越被各大高校重视。在传统学籍管理方式中，以人工管理为主、信息量大以及不方便储存等引起了大量资源投入却成效不大，现代化教育理念的革新使得整个高校的学籍管理急需更新。 本文基于VB语言和微软的.NET软件开发平台，以面向对象开发为主线，以UML进行快速建模，通过三层架构模式对该系统进行开发，后台数据库采用的是微软SQLSERVER，整个系统设计和实现以后可以满足当前高校对于学籍管理的实际需求。 本文首先对系统设计和...In recent years, as a university recruitment of students scale expands unceasingly, the management concept and management way is a great challenge, the original traditional management model and learning method of life in today's rapid development of the campus environment is very not harmonious. In it, the school roll status management also becomes more and more taken seriously by universities. In...学位：工程硕士院系专业：软件学院_软件工程学号：X201123061

The raindrop impact is very important in soil erosion problems on hill slopes, while the splash characteristics (especially the jet and mixing) are crucial in raindrop impact processes. Focusing on the jet and mixing features in this process, a series of numerical experiments and discussion are conducted in this study. The meshless Smoothed Particle Hydrodynamics (SPH) method is employed and validated with the theoretical solution and experimental data. Two groups of numerical experiments, focusing on the jet around the rigid surface and the mixing between the drop and different underlain water layers respectively, are carried out. In the first group of numerical experiments, the effect of incidence angle of the drop is discussed. A high speed jet strip is found near the rigid surface and varied with incidence angle of the raindrop. In the second group of numerical experiments, it is found that full mixing between drop and water layer only happened in a very close range around the impact zone while the outer zone is just simply driven away. Two kinds of mechanism on jet occurrence and mixing are proposed and explained based on the simulated results.

Study on the thermal performance of lightweight wall using Phase-Change Material

北九州市立大学博士(工学)Phase-change materials (PCM) can improve the thermal performance of lightweight walls, but their contribution efficiency is related to the PCM thermo-physical parameters, installation locations, and climatic conditions. However, the current research mostly focuses on a specific factor, which makes the existing conclusions too absolute and flawed. Therefore, the typical lightweight wall was taken as the research object in this paper, ascertained the basic scientific problem of the influence laws and suitability of different PCM parameters on the thermal performance of lightweight walls under different thermal boundaries through theoretical analysis, numerical simulation, and experiment. Meanwhile, evaluated the energy-saving potential of PCM lightweight wall and its economic feasibility in different climates/cities. The research results can provide a reference for decision-makers to select suitable PCM products in lightweight walls in terms of energy-saving and economics, and provide data support for manufacturers to develop innovative energy-saving lightweight wall products using PCM.doctoral thesi

Correspondence: LIU An-Ping to ZHOU Yan on the exhibition PROSPECT 96

The artist LIU An-Ping\u27 letter to ZHOU Yan is about the exhibition PROSPECT 96 that was held in Frankfurt, Germany, 1993. In addition, he talks about his feelings about the works by Wang Youshen and him in the show, and how German art media commented on these works .

Proposal: King of Paintings--- Peonies 方案：画王---《国色天香》

This proposal consists of three documents: the artist\u27s sketch of the art fair King of Paintings---\u27Peonies\u27 , an advertisement of this art fair, and an edited photograph of how the advertisement looks on the street. A black-and-white photograph of Mao Zedong and the artists and the literary workers at Yan\u27an is positioned as the background of this advertisement. This photograph was taken during the Speech at the Forum of Art and Literature in Yan\u27an in May, 1942. The artist edits the words The Jetset Company Releases the Art Fair \u27King of Paintings ----\u27Peonies\u27 in Commemoration of the XX Anniversary of the \u27Speech\u27 (1942-19xx) on the photograph. It is noted by the artist that the color of the words on the advertisement should be red, and the Chinese words King of Paintings (画王) at the art fair will use the calligraphy by Mao Zedong.

Artist Statement: East Wind No. 3

This artist statement, written in both Chinese and English, is about the artist\u27s conceptual art East Wind No. 3 东风3号 was executed at the National Art Museum of China in Beijing on Aug. 8th, 1995.

Artist Statement: A Legal Trespass

This document is written in both Chinese and German. It states that someone is instucted by Zhang to enter Apartment No. 1--505, Laodong Street, H city within 48 hours in the summer of 1994, and take photos at will. This conceptual art is designed by Xiaohong, likely the alias of Liu Anping. After the photographs are taken, this execution is named A Legal Trespass (正当侵犯) . According to Xiaohong, he reserves the right to judge whether this act is legitimate or not, because the conceptual art is executed inside his property. Note: the artist provides “Legitimate Violation” as the English name of this work, however, we think that “A Legal Trespass” is a more proper translation.
