基于Java平台的数据库桥接层Spring框架可靠性研究 摘 要 在Java编程环境中，无论是在web应用程序还是桌面应用程序中，都可以使用几个框架来简化应用程序的创建。如果我们更关注Java web框架，那么自2004年以来流行的Spring框架，特别是Spring框架的能力，它可以与各种其他框架（如Hibernate框架、Ibatis框架或MyBatis框架）以及其他一些框架相结合。本研究旨在比较使用Java编程语言构建的web服务应用程序与Spring框架的数据加载能力，尤其是与数据库桥接层（如Java数据库连接（JDBC）、Hibernate框架、MyBatis框架、，加上Hibernate和MyBatis中包含的具有as缓存数据层的附加框架功能。性能测试场景在Spring框架中创建一个web服务，然后由使用第三方代码构建的自定义测试脚本访问，并在特定时间段内重复调用它。 关键词： Spring Framework；Hibernate； Ibatis�

基于单片机的智能温度控制系统设计 摘要 本文提出一种基于单片机的智能温度控制系统的设计方法。智能温度控制系统分为四个部分：监控，加热器，控制过程和反馈回路。其中，温度检测电路设计有检测水的电导率的传感器。光耦合器MOC3041用于实现功率控制电路，其控制对象为具有220V交流电的1kW电加热器;键盘和显示电路SMC1602A包括四个按钮和LCD显示，实现人机交互;在单片系统STC89C52上，将传感器信号和键盘设置的目标温度进行比较使电源自动完成水温控制。通过静态和动态数据测试，结果表明该方法提供了一种实现实时采集和温度控制的有效方法。 关键词：微控制器;温度传感器;功率控制;SCR 1.介绍 温度是表示热和冷的物理量也是在我们的生产和生活最基本的物理量。温度测量与工业和农业生产的各种领域有关。温度控�

Communication Security We have now finished our study of the tools of the trade. Most of the important techniques and protocols have been covered. The rest of the chapter is about how these techniques are applied in practice to provide network security, plus some thoughts about the social aspects of security at the end of the chapter. In the following three sections, we will look at communication security, that is, how to get the bits secretly and without modification from source to destination and how to keep unwanted bits outside the door. These are by no means the only security issues in networking, but they are certainly among the most important ones, making this a good place to start. 1. IPsec IETF has known for years that security was lacking in the Internet. Adding it was not easy because a war broke out about where to put it. Most security experts believe that to be really secure, encryption and integrity checks have to be end to end (i.e., in the application

COMPARATIVE ANALYSIS OF AMERICAN AND EUROPEAN YACHTSMAN PROFILE FOR BETTER MARKETING PLACEMENT OF CROATIA AS TOURISM DESTINATION Ivo Andrijanić Natalija Parlov ABSTRACT: Countries develop their nautical tourism depending on their nature potentials and resources and in line with their national economic strategies. The main development determinant is a national strategy as the basis of all plans and activities. The nautical tourism development encourages tourism destination development and impacts on economic and social sustainability. Nautical tourism is a specific form of modern tourism trends whose extremely important and highly profitable economic influence is largely visible in numerous multiplicative effects. Renown world researches prove that nautical tourism is one of the most important economic activities in tourism sector, perceived in Croatia as one of the most competitive tourism products. The objective of this paper is to point at the necessity of differentiation

SYMPOSIUM: THE FUTURE OF THE LEGAL PROFESSION INTRODUCTION Robert P. Lawry[1] WHAT THESE PAPERS ARE AND ARE NOT The seven papers gathered together for this Symposium were commissioned for the First National Assembly of the Institute on the Future of the Legal Profession, held June 1-3, 1993, at Case Western Reserve University (CWRU) School of Law in Cleveland, Ohio. The Assembly was a joint venture of the American Bar Associations Center for Professional Responsibility, the American Bar Foundation, and the CWRU School of Law. The purpose of the Assembly was two-fold: (1) to bring to the attention of the legal profession key themes and issues it must confront if it is to sustain its vitality and contribute to the good of society into the 21st century; and (2) to encourage and assist leaders throughout the legal community to devise and implement plans and policies to help the profession achieve these goals. The papers were designed to provide a framework for discussion

The Role of Hydropower in Climate Change Mitigation and Adaptation: A Review Abstract Hydropower is a clean, renewable, and environmentally friendly source of energy. It produces 3930 (TW.h).aminus;1, and yields 16% of the worldrsquo;s generated electricity and about 78% of renewable electricity generation (in 2015). Hydropower and climate change show a double relationship. On the one hand, as an important renewable energy resource, hydropower contributes significantly to the avoidance of greenhouse gas (GHG) emissions and to the mitigation of global warming. On the other hand, climate change is likely to alter river discharge, impacting water availability and hydropower generation. Hydropower contributes significantly to the reduction of GHG emissions and to energy supply security. Compared with conventional coal power plants, hydropower prevents the emission of about 3 GT CO2 per year, which represents about 9% of global annual CO2 emissions. Hydropower projects may also h
