As a result, it is recommended that the use of open source as metaphor for ...

In this work we discuss the development of a web application in the domain of movie chains using a Blackboard architecture, which is a well-established style for solving the problem of control, communication and collaboration in a system; it has traditionally been accepted as adequate for heuristic problem solving though not generally used for web applications. We present and discuss how the Black ...

One of the characteristics in software development is that software systems require changes once they are deployed in an operational environment. When the software is being used by the intended audience it is almost inevitable that errors are found, requirements change or new requirements emerge because of changes in the business processes. Depending on the nature of these modifications and the li ...

There are many successful applications of Backpropagation (BP) for training multilayer neural networks. However, it has many shortcomings. Learning often takes long time to converge, and it may fall into local minima. One of the possible remedies to escape from local minima is by using a very small learning rate, which slows down the learning process. The proposed algorithm presented in this study ...

There are many successful applications of Backpropagation (BP) for training multilayer neural networks. However, they have many shortcomings. Learning often takes insupportable time to converge, and it may fall into local minima at all. One of the possible remedies to escape from local minima is using a very small learning rate, but this will slow the learning process. The proposed algorithm is pr ...

When people write a report that involves a complex argument towards a conclusion, they can use a design tool called the inference tree, which enables them to outline the argument, and quickly detect reasoning errors in the outline. Yet when the argument is very complex, the inference tree may spread over several pages, so that writers may often have to flip back and forth between those pages. To p ...

This tutorial aims at taking the participants through the concept and architecture of Web services, their components such as servlets, and JSPs; concept and usage of WSDL, and JAX-RPC-based web services. Furthermore, we introduce the concept of portals, portal page and portlets. A small part of the tutorial is devoted to the deployment practices of both - Web services and portlets. Relevant deploy ...

Portals are often seen as an appropriate method of informing clients. A problem of all web based solutions to informing clients is that the web is passive: clients must come to the web site. Approaches to research into use of portals are usually socio-technical, with common use of statistical techniques applied to survey results. Here we argue, informed by two detailed cases, that an actor network ...

An exploratory survey of business professionals from a broad range of organizations indicates that potential intranet benefits are both difficult to achieve and highly interrelated. Although many organizations implement intranets in the hope of generating cost savings or improving knowledge sharing across organizational units, this study indicates that the only likely benefit of implementing an in ...

The overall aim of this study is to determine the performance of selected web-based dynamic middleware systems that are used for designing and implementing dynamic web application systems. This is necessary in a world where more applications are moving to the web, and slow performance of such applications can discourage users, thereby reducing profit, and reduce programmers’ productivity and quali ...

A telecommunication network produces daily large amounts of calling data which contain hidden and valuable knowledge. This knowledge can be used in determining the calling patterns of customer, finding too thrifty customers, also for locating the best area to concentrate on in order to boost profits. In this paper, we designed an algorithm named CLOTELE which is based on the ideas of the pattern-g ...
