Design and Implementation of Human Resources Management System In Electricity Industry

随着电力行业规模不断扩大，人力资源管理成本不断提高，传统的纸质管理方式已不能满足企业内部的管理需求。为了满足企业不断扩大的信息化需求，同时由于电力行业的特殊性，如员工数量巨大，薪资计算复杂，考核标准灵活多变等特点，传统的人力资源管理系统不能充分满足电力行业的需要，因此为了使人力资源管理部门从重复繁杂的日常管理事务中解脱出来，提高企业竞争力，非常迫切地需要开发出一款适用于电力行业本身的人力资源管理系统。 本文针对电力行业人力资源管理的业务需求，基于J2EE技术设计并实现了一套适用于电力行业的人力资源管理系统。其主要研究内容如下： 1、本文设计并实现了电力行业人力资源管理系统，涵盖了“人事信息...Human resource management costs continue to increase with the electric power industry being expanding. The traditional paper-based management approaches have failed to meet internal management needs. Traditional human resources management system can’t fully meet the needs because of the particularity of the power industry, such as the huge number of employees, the complexity of the payroll calcula...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X201023034

This paper presents and demonstrates the principles and mechanisms of several typical GNPs-based methods for gene mutation and SNP analysis , aiming to provide some ideas and references for further studies.福建省青年科技人才创新项目(No.2006F3128)资助

A Wide Band Strong Acoustic Absorption in a Locally Network Anechoic Coating

Composite materials with interpenetrating network structures usually exhibit unexpected merit due to the cooperative interaction. Locally resonant phononic crystals (LRPC) exhibit excellent sound attenuation performance based on a periodical arrangement of sound wave scatters. Inspired by the interpenetrating network structure and the LRPC concept, we develop a locally network anechoic coating (LNAC) that can achieve a wide band of underwater strong acoustic absorption. The experimental results show that the LNAC possesses an excellent underwater acoustic absorbing capacity in a wide frequency range. Moreover, in order to investigate the impact of the interpenetrating network structure, we fabricate a faultage structure sample and the network is disconnected by hard polyurethane (PU). The experimental comparison between the LNAC and the faultage structure sample shows that the interpenetrating network structure of the LNAC plays an important role in achieving a wide band strong acoustic absorption

Analysis on epidemiological charateristics of chlamydia trachomatis infection in Jiangsu Province,2006-2011

目的了解江苏省2006-2011年生殖道沙眼衣原体感染的流行病学特征,为制定防治生殖道沙眼衣原体感染的策略提供科学依据。方法收集2006-2011年江苏省通过中国疾病预防控制信息系统报告的生殖道沙眼衣原体感染病例资料,并对资料进行流行病学分析。结果 2006-2011年,江苏省生殖道沙眼衣原体感染发病率呈快速上升的趋势,2006年为0.12/10万,2011年为3.15/10万,发病率年均增长速度为92.23%;在报告的5 859例病例中,男女性别比为0.3∶1,各年生殖道沙眼衣原体感染男女性别差异有统计学意义;发病年龄主要集中在20~29岁年龄组,占50.96%;江苏省生殖道沙眼衣原体感染报告病例主要集中在苏南和苏中的较发达城市;主要以家庭及待业者和工人为主。结论江苏省生殖道沙眼衣原体感染发病率快速增长,应加强对生殖道沙眼衣原体的防治,以控制其感染的快速流行。江苏省医学重点人才(RC2011086);江苏省医学重点人才(RC2011087); 江苏省科技项目(Y201029

Locally resonant phononic woodpile: A wide band anomalous underwater acoustic absorbing material

To meet the demand of modern acoustic absorbing material for which acoustic absorbing frequency region can be readily tailored, we introduced woodpile structure into locally resonant phononic crystal (LRPC) and fabricated an underwater acoustic absorbing material, which is called locally resonant phononic woodpile (LRPW). Experimental results show that LRPW has a strong capability of absorbing sound in a wide frequency range. Further theoretical research revealed that LRPC units and woodpile structure in LRPW play an important role in realization of wide band underwater strong acoustic absorption

让城市总体规划更有用

今天这场学术对话的主题是\"让城市总体规划更有用\"。城市总体规划是一个城市全局性、综合性规划,在统筹城乡发展、优化空间开发格局、合理配置空间资源、保障公共利益等方面发挥着战略引领和刚性控制作用,是城市重要的公共政策和指导城市建设的法定依据。无论从城乡规划法律的制度设计还是从城市总体规划的属性来看

Design and Implementation of Task-balanced Network Storage for Images

由于业务不断拓展，网站运营商面临大数据的处理压力，特别是大量图片的并发存储和检索会给网站性能带来巨大影响，例如访问速度下降、文件系统I/O读写频繁，甚至会引发网站崩溃。大企业通常购买高端硬件及配套解决方案进行网站升级，但中小型企业往往无法承担升级的高成本。因此，本论文设计和实现适用于中小型网站的图片网络存储方案，以满足大量图片并发处理的需求。 图片网络存储方案核心是图片服务器的设计与服务接口的实现。本方案可支持多个图片服务器，并通过任务均衡分配进一步提高服务性能和可靠性。图片服务接口利用.NET的缓存技术实现任务均衡分配，并在图片服务器上优化图片存储策略。网站开发人员可调用服务接口向图片服务...With the business growing, most enterprises face the problems of bulk data processing.
