This aluminium salt is largely used up to 25% (w/w) in 90% of antiperspirants. Investigations were thus designed to study the neurotoxicity of this ...

Such activities are generally dynamic, cooperative, long-lived, interactive, and non-prescriptive. We propose a new multi-agent transaction model, which is based on extended transactions and multi-agent technologies. The novelty of this model is that it automatically customises transactions to the requirements of the design activities. In addition, this model is believed to improve concurrency and fault tolerance, facilitate interaction and co-operation of participating systems involved in design activities.

Depending on the negotiation mechanism such search space can be dynamic wherein agents may be cooperative or non-cooperative. In a realistic negotiation, agents are unwilling to reveal their utility functions to their opponents or collaborators.

In the prevailing models for QoS management, QoS resolution is achieved by table look-up, a feature that makes table access the focal point of activity. This approach suffers from two limitations, namely, an inability to deal with unexpected QoS requests, and a reliance on human intervention for update of information. This paper is concerned with the presentation of an architecture for supporting automated QoS resolution through verification. The architecture is modular and the QoS resolution function is performed by a subsidiary component, which combines knowledge base with resolution mechanism. This separation of concerns and the support for flexible QoS management has the advantage of accommodating new forms of QoS requests, and of minimising human intervention. An implementation of the QoS resolution architecture is presented in terms of Timed Automata. In addition, a framework is also introduced for extending QoS architectures such as ITSUMO.

Such activities are generally dynamic, cooperative, long-lived, interactive and non-prescriptive. We propose a new multi-agent transaction model, which is based on extended transactions and multi-agent technologies. The novelty of this model is that it automatically customises transactions to the requirements of design activities. In addition, this model is believed to improve concurrency and fault tolerance, facilitate interaction between and co-operation among the participating systems involved in design activities. The proposed model is formally specified using CCS (Calculus of Communicating Systems) language. Formalism is crucial to model the correctness, reliability, and recovery of multi-agents transactions, given the complex and unreliable nature of the Web-based design activities.

Conceptually the paper is divided into three parts. The first part presents the salient features of data mining and its symbiotic relationship to data warehousing. In the second part of the paper, historical serial documents are introduced, and the Ottoman Tax Registers (Defters) are taken as a case study. Their conformance to the data mining approach is established in terms of structure, analysis and results. A high-level conceptual model for the Defters is also presented. The final part concludes with a brief consideration of the implication of data mining for historical research.

Several e-learning systems have been developed to address this issue. However, they usually provide the same material in the same sequence irrespective of the characteristics of the students, such as their knowledge level and learning style. In this paper, an approach to learning style adaptivity is proposed for the teaching of computer security. An e-learning system was developed to provide more personalised and adaptive learning, based on the information perception style of the Felder-Silverman model. This is the dimension of learning style, which has received the least attention in published research. In the approach, a personalised sequence of learning material is generated based on an individual learning style. The approach is evaluated in order to determine its effectiveness in learning provision. An experiment conducted with sixty subjects produced significant results. They indicate that matching computer security learning material, according to the learning style of the students, yields significantly better learning gain and student satisfaction than without matching.

The project is aimed at exploiting existing Internet technologies in implementing new processes and in providing an integrated and structured teaching environment. This work presents a rationale for a new approach to training and details the resulting re-engineering process. Four main processes were identified in the re-engineering of the training programme: skill identification, curriculum development, training and evaluation of the programme. The implementation of the new programme has focussed on curriculum development with an emphasis on a suite of software tools that were developed in order to illustrate and support business and industrial processes. A number of modules have been written using Web development technologies, including HTML and Java.

Agent technology is seen as a critical factor in knowledge acquisition in semantically rich environments, as exemplified by the Semantic Web. In addition the development and delivery of learning content is facilitated by the adoption of eLearning standards. In this paper we consider an eLearning framework where the learning process is mediated by software agents and supported by a knowledge base on learner profiles and skill maps. The roles of the agents are closely associated with the different stages of the learning process. The proposed approach is put into perspective through a brief discussion of some of the challenges that eLearning development is facing.

A high level of satisfaction can increase the motivation of students, their engagement and experience, and therefore improve their learning. This paper is concerned with the investigation of the effect of adaptation based on learning style on students' satisfaction. An adaptive approach, which involves the construction of personalised learning paths based on learning style, was implemented in an adaptive e-learning system. A controlled experiment in this learning environment was conducted with sixty undergraduate students to evaluate their level of satisfaction with the system. The results indicate that the students were generally satisfied with their learning experience. It can be concluded that adaptation of learning content according to learning style can improve student satisfaction and enhance their experience and motivation.

However multiple disciplinary teams in different departments and companies often use different systems with different modelling methods and techniques. While the parallelism of this approach can reduce the design life cycle, the complexity of the optimisation problem can lead to difficulties. Agent technology can alleviate some of the difficulties of concurrent design. In this paper, we present an architecture in which agent technology is used to model interactions between design systems, and thereby enable design agents from various design disciplines to explore the design problem and solution space. We also introduce a multiple-evolutionary approach with an automated negotiation mechanism to enable agents to exchange design solutions and to reach an agreed optimised solution for a global design problem.

Autonomous agents representing different organizations need to implement a set of behaviors in addition to their problem solving behaviors in order to facilitate the coordinated exception handling processes across organizational boundaries. In this paper we review the limitations of the current domain independent exception handling approaches and propose a flexible approach to exception handling in MAS. The approach works by incorporating the exception handling services provided by the MAS infrastructure owner and local exception handling mechanism of individual agents. It allows the agent to use system provided exception handling service for all of its protocol related (social) exceptions or use its local exception handling mechanism to deal with a subset of these exceptions. It is claimed that this provides flexibility in exception han...

This paper presents an architectural approach to QoS evaluation and admission control, based on the modelling of both system behaviour and QoS requirements. Two aspects are considered. The first refers to QoS management, and to a component-based architecture for QoS evaluation. The second illustrates the approach with the help of a case study based on a Personal Area Network. The proposed approach is model-based and makes use of models representing both behaviour and QoS aspects of the system via Timed Automata. The compatibility of the mechanism with architectures, which promote QoS management in its own right, such as ITSUMO, is also highlighted.

In contrast, adaptive e-learning systems take into account learner characteristics such as learning style and level of knowledge in order to provide more personalised learning. The contribution of this paper is threefold. First, a generic adaptive framework aimed at enhancing learning is proposed. Second, a specific approach to adaptivity based on learning style is put forward within the framework. Third, the framework is validated and the approach is evaluated in order to determine their effectiveness in learning provision in an adaptive e-learning system. An experiment conducted with 60 participants produced positive results. They indicate that adapting instructional material according to learning style yields significantly better learning outcome and learner satisfaction than without adaptation.
