This paper presents the use of a modified ant colony optimization algorithm and interactive web technologies for the problems of real-time path planning and navigation for an autonomous mobile robot. Assume that the mobile robot serves in an office building for delivering documents and packages, and all staff in different locations can assign tasks to the robot via a web-based application. Ther...

This chapter focuses on recommender systems based on the coherent user’s browsing patterns. Biclustering approach is used to discover the aggregate usage profiles from the preprocessed Web data. A combination of Discrete Artificial Bees Colony Optimization and Simulated Annealing technique is used for optimizing the aggregate usage profiles from the preprocessed clickstream data. Web page recom...

Accurate and reliable time is necessary for financial and legal transactions, transportation, distribution systems, and many other applications. Time synchronization protocols such as NTP (the Network Time Protocol) have kept clocks of such applications synchronized to each other for many years. Nowadays there are many commercial GPS based NTP time server products at the market but they almost ...

Traditionally, the earthmoving operations have been developed based on the minimum cost per production criterion. Nowadays, due to the negative impacts of the emissions on the environment, there is an increasing public awareness to reduce the emissions from the earthmoving operations. Different management strategies can be employed to reduce emissions, amongst other things, which can also resul...

A Web server’s constraint on the number of pages it can serve simultaneously is largely because of two factors: the bandwidth available and the Web server itself. When a website is popular and if there is only one web server responding to all the incoming HTTP requests for a website it may be possible that the capacity of the web server may not be able to handle high volumes of incoming traffic...

A Web client request traverses four types of Web caches, before the Web server as the origin of the requested document is reached. This client-to-server path is continued to the backend DB server if timely and transaction-consistent data is needed to generate the document. Web caching typically supports access to single Web objects kept ready somewhere in caches up to the server, whereas databa...

In the traditional project of industry control, the field operator is the only man who watches production condition at the production spot. Enterprise administers cannot obtain real-time production status and make real-time decision if they don’t reach the production spot. Because of the development of Embedded Web Server such status is being changed. The remote monitor and control mode based o...

This is a case study on using DSP board to construct an encryption/decryption module embedded in a E-Commerce web server. The idea of using DSP is to push beyond the key length limits of encryption/decryption algorithms and computational power in software environment while avoiding the heavy investment in dedicated hardware encryptor/encryptor. The low cost, high computational power, high flexi...
