In high technological complexity industrial systems, the operators' role is more and more critical. They need deeper and deeper specialization and a continuous monitoring of both process and plant to achieve high efficiency and proper working. That requires a continuous training and upgrading of the operator knowledge to react promptly and properly to the different plant/process situation to manage...
In the paper, a new method of extracting HTML Tree from web pages is proposed. Its main idea is that the parts of web pages which are not easy to parse including tags and attributes should be handled previously, then the remaining parts are tidied and parsed, and then both the two former extracted parts are deposited in the tree. As integrated the tidying process and the parsing process, the new method...
Recent endeavors in addressing the challenges of the current and future Internet pursue a clean slate design methodology. Simultaneously, it is argued that the Internet is unlikely to be changed in one fell swoop and that its next generation requires an evolutionary design approach. Recognizing both positions, we claim that cleanness and evolution are not mutually exclusive, but rather complementary...
Nowadays, content distribution is of high attention in peer to peer information systems. There are two main problems that could be mentioned in this context. The first problem is how to disseminate fragments of information efficiently and the next is to avoid missing same rare fragments towards end of download. For overcoming these problems, a new mechanism is presented in this paper which uses gossip...
Scientific visualization is the process of transforming raw numeric data into a visual form, and is a key element of computational science. While many tools exist, they are unnecessarily difficult to use. This complexity increases time to insight and inhibits casual inquiry. The complexity derives from the need to support arbitrarily formatted data and many visualization algorithms. EnVision addresses...
The generation and marking of complex exercises always is a very difficult task. This paper presents the concept and realisation of an e-learning tool that provides predefined or automatically generated calculation exercises. Students may practise where- and whenever they like to via the Internet. Their solutions are marked automatically while considering consecutive faults and without any intervention...
Next generation networks, as well as the Future Internet, need to provide context-sensitive services that adapt to changing user needs, business goals, and environmental conditions. This article presents a novel autonomic management methodology and associated architecture to make the networks and devices that it manages responsive to context-aware business needs. This approach provides a mapping between...
Sometimes the backbone network of Internet experiences congestion because traffic is not distributed rationally. This fact may lead network resources utilized inefficiently. The main idea for load balancing is to alter the route for some traffic. But current approaches with this idea often get such a long route that decrease the quality of service. This paper presents a new flow routing adjustment...
In this paper, we present a scheme of steganalysis of JPEG images with the use of polynomial fitting and computational intelligence techniques. Based on the Generalized Gaussian Distribution (GGD) model in the quantized DCT coefficients, the errors between the logarithmic domain of the histogram of the DCT coefficients and the polynomial fitting are extracted as features to detect the adulterated...
