[Documents] CommunicatorP2C_Prospectus

Description: The P2C communicator is intended for remote readout of electricity meters on the level of industrial consumption according to the protocol complying to the IEC 61107 standard. It enables bi-directional data transmission from a meter to a data processing centre and vice-versa. The communicator is provided with two communication interfaces - one for the access to the meter, and another for data transmission to the billing centre. The communicator reads meters via CS interface (20 mA current loop by DIN 66348) or via RS 232 interface. Data are sent to the centre via various communication media (PSTN, ISDN, GSM or CaTV network). The SEP2W software enables parameter setting and readout of the communicators-The P2C communicator is intended for remote readout of electricity meters on the level of industrial consumption according to the protocol complying to the IEC 61107 standard.

[JSP/Java] onlineweb

Description: 这是一个JSP在线考试系统，后台数据库为MySQL。这是一个完整的web应用程序，实现了教师出题、学生在线考试(自由测试、单元测试、模拟考试)、错题本，以及相关的系统维护功能。在线测试的功能主要包括三部分：教师出题、学生在线考试和系统维护：系统维护包括对年级科目、知识点和模拟考试这些信息的维护-Technological innovations have already started to transform the way universal access is being extended to rural and remote areas. In some countries, mobile technologies have been instrumental in extending access to communication services to disadvantaged parts of the population. In developing and least developed countries, the rapid expansion of mobile networks increased the availability of services, allowing regions access to basic phone services not previously reached by the PSTN. In many cases, the extension of mobile networks did not have to be supported by subsidies. Mobile technologies may offer access to data services at speeds that – though not similar to fixed broadband technologies – provide a wide national coverage. However, high prices for data access and bit caps, which are, at times, quite restrictive, has meant that mobile broadband access technologies are still far from being a substitute for fixed broadband access technologies, although some operators are now
