Online communities that form social networks became extremely important in many tasks related with information processing, presentation, navigation, especially in context of web-based information systems. Web-based information systems employing communities could benefit from the classical studies of human social interactions social network analysis. In this paper, we present an extensible open-source JAVA-based framework for social network analysis which can be used either a a stand-alone application with its own GUI as well as a library within third-party software projects developed in JAVA. We provide not only a standalone desktop application, but the whole framework, which allows anyone to incorporate results of social networks analysis into their own project, which would possibly boost up its functionality, enhance the results etc.

Many documents available on the current web have quite a complex structure that allows to present various kinds of information. Apart from the main content, the documents usually contain headers and footers, navigation sections and other types of additional information. For many applications such as document indexing or browsing on special devices, it is desirable that the main document information should precede the additional information in the underlying HTML code. In this paper, we propose a method of document preprocessing that automatically restructures the document code according to this criteria. Our method is based on rendered document analysis. A page segmentation algorithm is used for detecting the basic blocks on the page and the relevance of the individual parts is estimated from the visual properties of the text content.

The availability of services can be comprimised if a service request sent to the web services server hides some form of attack within its contents. This article presents AIDeM (An Agent-Based Intrusion Detection Mechanism), an adaptive solution for dealing with DoS attacks in Web service environments. The solution proposes a two phased mechanism in which each phase incorporates a special type of CBR-BDI agent that functions as a classifier. In the first phase, a case-based reasoning (CBR) engine utilizes a Naives Bayes strategy to carry out an initial filter, and in the second phase, a CBR engine incorporates a neural network to complete the classification mechanism. AIDeM has been applied within the FUSION@ architecture to improve its current security mechanism. A prototype of the architecture was developed and applied to a case study. The results obtained are presented in this study.

This paper proposes a novel methodology of distributed PLM platform deployment. It efficiently incorporates PLM technologies to support collaborative product development in a global enterprise with multiple distributed sites. The methodology systematically analyzes a company's PLM requirements from the Organizational, Application, and Data perspectives. A customized network configuration plan can then be developed for the company to build up a performance-oriented, cost-effective, and easy-to-maintain collaborative PLM platform. A case study is conducted to verify the feasibility of our method. The promising result of the case study gives rise to the potential and possibility to derive further research based on this work.

This paper details a method of determining the uncertainty of dimensional measurement for a three dimensional coordinate measurement machine. An experimental procedure was developed to compare three dimensional coordinate measurements with calibrated reference points. The reference standard used to calibrate these reference points was a fringe counting interferometer with the multilateration technique employed to establish three dimensional coordinates. This is an extension of the established technique of comparing measured lengths with calibrated lengths. Specifically a distributed coordinate measurement device was tested which consisted of a network of Rotary-Laser Automatic Theodolites (R-LATs), this system is known commercially as indoor GPS (iGPS). The method was found to be practical and able to establish that the expanded uncertainty of the basic iGPS system was approximately 1 mm at a 95% confidence level.

This research addresses a hybrid flow shop scheduling problem using a simulation approach. The scheduling problem is characterized by two features---blocking scheduling and sequence dependent setup time. The objective of the scheduling is to minimize the makespan, i.e. the time needed to complete all jobs. Different dispatching rules have been evaluated and their relative performances have been compared. The experimental results indicate that the commonly good dispatching rules in usual job shop scheduling like FIFO and SPT do not perform better or even much worse than LPT in the studied scheduling problem. The main reason is the special characteristic of the scheduling problem. Although this paper proposes some dispatching rules which perform well in minimizing the makespan, further researches are needed to find better dispatching rules for this kind of scheduling environment. The simulation uses the Flexism software as the coding and testing environment.

The integration of people with intellectual disabilities into working and social environments is one of the main issues in applying Information and Communication Technology (TCT) into Assistive Technology field. In order to solve this problem, the use of intelligent Tutoring Systems (ITSs) is a fact among the attendance community. Human Emotion Management System (HEMS) enhances the performance of ITSs. In this work a HEMS is included in a new ITS system (LAGUNTXO) which adds user affective information. People with intellectual disabilities and elderly need physical and intellectual support. This may be achieved by a HEMS which attempts to solve critical situations, like those presented in blockage stages. In this paper, new methods and material to analyze and classify human emotions and corresponding elicited emotions have been tested. This study has provided finding emotional changes which give the opportunity of detecting blockage situations in people with disabilities. The evaluation results of the created elicitation material and methods indicate a high level of accuracy with respect to others classically presented in the literature.

An optimization-based approach is developed for routing a just-in-time (JIT) supply system, which requires for high-frequency, small quantity deliveries. The mathematical model called common frequency routing problem (CFR) is formulated. To solve the model, tabu search strategies have been developed. The utility of the approach is demonstrated through a computational experiment. The result shows that in the same demand conditions, the total transport distance is shorten, the total times of vehicle trips is reduced and side inventory decreases.

One of the most significant paradigm shifts of modern business management is that individual businesses no longer compete as autonomous entities but rather as supply chains. However, the majority of companies, especially small and medium enterprises, fail to design and manage their supply chains in a profitable way, as it is difficult to understand the complex dynamics of Supply Chain Management (SCM). In this paper we argue that agent technologies can provide an intelligent solution to the improvement of SCM. We present a multiagent-based framework for simulating supply chain (SC) operation and re-configuration, with the vision of helping to improve overall SC performance and coordination. The suggested key innovation lies in the better explanation of simulation results and its attractiveness to SCM practitioners. Its theoretical conceptualisation, a logic-based formalisation and the system's architecture that combines agent technologies with business rules and business process modelling are presented.
