A general approach for building Linux on sensor node Imote2

Recently, Wireless Sensor Network (WSN) has become a significant research field. Imote2 is an advanced WSN platform, which supports Linux operating system. However, building Linux on Imote2 is not trivial. In this paper, we introduce a general approach in detail, including installing bootloader, communication between Imote2 and host PC, as well as loading kernel and file system. After it, some fundamental configurations on Imote2 and host PC are presented. We further provide test method by sending and receiving radio on Imote2. More development on Imote2 with Linux can benefit from our approach.

Power generation maximization of distributed photovoltaic systems using dynamic topology reconfiguration

The ‘mismatch losses’ problem is commonly encountered in distributed photovoltaic (PV) power generation systems. It can directly reduce power generation. Hence, PV array reconfiguration techniques have become highly popular to minimize the mismatch losses. In this paper, a dynamical array reconfiguration method for Total-Cross-Ties (TCT) and Series–Parallel (SP) interconnected PV arrays is proposed. The method aims to improve the maximum power output generation of a distributed PV array in different mismatch conditions through a set of inverters and a switching matrix that is controlled by a dynamic and scalable reconfiguration optimization algorithm. The structures of the switching matrix for both TCT-based and SP-based PV arrays are designed to enable flexible alteration of the electrical connections between PV strings and inverters. Also, the proposed reconfiguration solution is scalable, because the size of the switching matrix deployed in the proposed solution is only determined by the numbers of the PV strings and the inverters, and is not related to the number of PV modules in a string. The performance of the proposed method is assessed for PV arrays with both TCT and SP interconnections in different mismatch conditions, including different partial shading and random PV module failure. The average optimization time for TCT and SP interconnected PV arrays is 0.02 and 3 s, respectively. The effectiveness of the proposed dynamical reconfiguration is confirmed, with the average maximum power generation improved by 8.56% for the TCT-based PV array and 6.43% for the SP-based PV array compared to a fixed topology scheme.

SSH框架在Web项目开发中的设计与实现

在Web项目开发中,一个良好的框架可以加快开发速度,降低成本,减少工作量,同时可以使Web项目具有良好的扩展性和移植性。基于Spring MVC+Spring+Hibernate(简称SSH)的项目以其快速的开发效率和良好的扩展性,成为中小企业应用主流的框架组合。Spring MVC是一个基于MVC设计模式的框架,是Spring的子项目,主要负责表现层和控制层的功能,例如响应请求等。Spring是一个实现IoC和AOP的容器,降低组件间的耦合度,可以整合和支持Spring MVC和Hibernate等主流框架,使业务逻辑更加清晰。Hibernate负责管理数据持久化,实现与数据库相关的CRUD操作。以购书网站的后台管理系统为例,重点说明SSH框架在Web应用系统的后台开发中的应用。
