The use of novel analytical techniques (such as data clustering and decision trees) that can model and predict patient disease outcomes has great potential for assessing disease process and progression in Alzheimer's disease and mild cognitive impairment. For this study, 43 different variables (generated from image data, demographics and clinical data) have been compiled and analyzed using a modified clustering algorithm. Our aim was to determine the influence of these variables on the incidence of Alzheimer's and mild cognitive impairment. Furthermore, we used a decision tree algorithm to model the level of "importance" of variants influencing this decision.

This paper discusses a problem of pricing and replenishment decisions for a system consisting of a single vendor and a single retailer. The retailer faces a stochastic customer demand, and adopts a continuous review (r,Q) policy for replenishing inventory from the vendor. At the beginning of the time horizon, the retailer chooses his expected sales target, and satisfies customer demands with resultant price that depends on the sales target. Taking the optimal centralized solution as benchmark, we analyze the system performances with wholesale-price contract and revenue-sharing contract, respectively. Numerical computations show that the performance of the revenue-sharing contract dominants the wholesale-price contract in most of the regular cases.

Water quality management policies on a river basin scale are of special importance in order to prevent and/or reduce pollution of several human sources into the environment. Industrial effluents represent a priority issue particularly in Urban Wastewater Systems (UWS) that receive mixed household and industrial wastewaters, apart from rainfall water. In this paper, we present an analysis and an implementation of normative agents which capture concrete regulations of the Catalan pollution-prevention policies. The implementation of the normative agents is based on situation calculus.

This paper presents a novel technique to semi-automatically identify metadata for documents when installing a knowledge management system. Document management systems often deal with large collections of documents. This vast amount of information needs to be searchable for the knowledge worker. Supporting techniques are needed to aid the knowledge worker in his search for information. Many of these techniques are based on the presence of metadata for each document. The techniques presented in this paper are based on a novel approach called multilayer clustering. Using this clustering technique, documents can be assigned to one or more document types. Besides this assignment to a specific type, properties and values are assigned to this document based on term networks extracted from this document. The preliminary tests presented in this paper were performed on a public and several private dataset. The results obtained from the tests indicate that this approach is promising.

This work presents improvements in the communication protocol and service coordination mechanism of the HoCa architecture, a multi-agent based architecture designed to facilitate the development of pervasive systems that proposes a new model where multi-agent systems and service oriented architectures are integrated to facilitate compatible services. A coordinator agent proposes a new planning model, where the complex processes are modeled as external services. The agent acts as coordinators of Web services that implement the four stages of the case-based planning cycle. One of the main aims of the pervasive systems is to be able to adapt themselves in execution time to the changes in the number of resources available, the mobility of the users, variability in the needs of the users and failures of the system. Multiagent systems are suitable to resolve these issues due to their capabilities such as autonomy, reactivity, pro-activity, mobility, etc.

Many biological processes involve synchronization between nonequivalent systems, i.e, systems where the difference is limited to a rather small parameter mismatch. The maintenance of the synchronized regime in this cases is energetically costly [1]. This work studies the energy implications of synchronization phenomena in a pair of structurally flexible coupled neurons that interact through electrical coupling. We show that the forced synchronization between two nonidentical neurons creates appropriate conditions for an efficient actuation of adaptive laws able to make the neurons structurally approach their behaviours in order to decrease the flow of energy required to maintain the synchronization regime.

PAAMS, the International Conference on Practical Applications of Agents and Multi-Agent Systems is an international yearly stage to present, to discuss, and to disseminate the latest advances and the most important outcomes related to real-world applications. It provides a unique opportunity to bring multi-disciplinary experts, academics and practitioners together to exchange their experience in the development of Agents and Multi-Agent Systems. This volume presents the papers that have been accepted for the 2010 edition. These articles capture the most innovative results and this years advances. Each paper has been reviewed by three different reviewers, from an international com-mittee composed of 82 members from 26 different countries. From the 66 submissions received, 19 were selected for full presentation at the conference, and 14 were accepted as short papers. Moreover, PAAMS'10 incorporated special ses-sions and workshops to complement the regular program, which included 85 ac-cepted papers.

Risks assessment in capacity expansion project is governed by large number of complex factors. Traditionally, tools like risk registers, risk management spreadsheets, brain storming sessions, individual decisions and so on are used to identify risks in these projects. As a result, many risks remain unidentified, and avoiding failure becomes impossible. Our work aims to resolve this dilemma of decision maker by providing a tool based on text mining and ontology driven approach to assist a decision maker not only by providing all the risks and their prevention measures that can emerge after and during capacity building project but also by evaluating cost associated with them. By including the cost, our model is more realistic in practice. This paper introduces the software we prototyped to achieve our goal.

Given an efficient process, five-axis milling is a productive technology that can help production industries in countries with a high level of workers' wages to remain competitive on the global market. For planning the required machining processes, engineers have to be supported by methods and tools. In current research at WZL of RWTH Aachen and IPT of Fraunhofer Gesellschaft, a CAx framework for simulation-based planning of complex machining processes is developed. This software tool, embedded in a CAM system, bases on coupled models of numerical controllers, machine tools, control loops and cutting processes. For supporting an iterative optimization without long computational times, the optimization concept focuses on the identification of critical areas in NC programs regarding effects of different domains (e.g. control, machine, and process). These effects can be determined by applying a sensitivity analysis in combination with tracing tools, as it is exemplarily presented for NC effects.

In this paper, we describe the design of a RFID-enabled container yard management (RFCYM) system in harbour to enhance operational efficiency. Design and fabrication of an active RFID reader and tag for monitoring container is presented. This study demonstrates the feasibility of acquisition of container information using active UHF RFID technology. Finally, we mention the limitations of this study and several future development directions.
