EUROPEAN SIMULATION AND MODELLING CONFERENCE 2009

Abstract
Memory is one's mental ability to store, to retain, and recall information, representing past and future, our dreams and/or expectations. However, as the human been ages, the capacity of remembering decreases as well the ability to pile up new memories, therefore affecting our quality-of-living and lowering our self- esteem. This configures a social and human dilemma. With the present work we intend to address some of these problems, in terms of a Personal Memory Assistant (PMA), in order to help the user to remember things and occurrences, making it in a proactive mode. It will also cater for some form of relaxation on the part of the user.

TRENDS IN PRACTICAL APPLICATIONS OF AGENTS AND MULTIAGENT SYSTEMS

Abstract
Memory is one of our most precious goods has it gives us the ability to store, retain and recall information thus giving a meaning to our past and help us to envision our future, dreams and expectations. However, ageing decreases the capacity of remembering and the capacity to store new memories, thus affecting our life quality. These presented problems configure a social and human dilemma. With the presented work we intend to address some of these problems, thru the use of the Personal Memory Assistant (PMA) concept in order to help its user to remember things and occurrences in a proactive manner. We will also address socialization and relaxation events that should be part of the user's life. With the use of a Multi-Agent System to implement the PMA, the objectives can be achieved in a ubiquitous and highly configurable manner. It is presented here the platform concept, scheme and the agent characteristics and their contribution to each and every agent.

EUROPEAN SIMULATION AND MODELLING CONFERENCE 2008

Abstract
Researchers are giving special attention to innovative healthcare projects in order to reduce medical service costs and to deal with the population ageing. The Virtual e-Care was born taking those goals in mind. An intelligent and proactive system has been prototyped, Supporting group decision making techniques, idea generation, argumentation and the quantification of the quality of information. In this paper it is simulated a virtual Assisted Living Environment, based in a solid agent-based architecture. Special attention is given to the monitoring system.

QUALITY OF KNOWLEDGE IN GROUP DECISION SUPPORT SYSTEMS

Publicação
ICAART 2009: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON AGENTS AND ARTIFICIAL INTELLIGENCE

Abstract
In this work it is addressed the problem of knowledge evaluation in a VirtualECare Group Decision Supporting System (GDSS), in terms of an Multi-valued Extended Logic Programming language, which is aimed at sustaining online healthcare services. Indeed, reasoning with incomplete and uncertain knowledge have to be dealt with, due to the particular nature of the healthcare services, where the awful consequences of bad decisions, or lack of timely ones, demand for a responsible answer.

Electronic voting: An all-purpose platform

ELECTRONIC GOVERNMENT, PROCEEDINGS

Abstract
It is generally considered that a key component of electronic government in the future will be electronic voting, as a means of facilitating the participation of citizens in elections and public debates. However, a long path has to be pursued before electronic voting, particularly if based on Internet, is accepted as a reliable system alternative to conventional methods. In this paper, we propose a new and simple platform, based on open software, which can be used primarily in small to medium sized communities, as a means to build confidence and experience for future larger elections. We try to provide adequate answers to multiple requirements, such as accuracy, democracy, privacy, verifiability and mobility. This can be done by establishing a distributed system which supports the different roles of a voting system and by using cryptography techniques in the interactions between these components.

Ambient Assisted Living

Abstract
Population aging brings increased social problems. Solutions for this new reality must be devised. Providing care services at home may benefit patients, health service providers, and social security systems and needs to be seen as a possible solution for those social problems. By maintaining the patient at home, in his or her own environment, care services costs can be diminished and, at the same time, the comfort and well-being of the person in need are significantly increased. To pursue this goal, we explore the advantages that ambient assisted living can bring to people in a home environment, focusing on the problems of health care services at home. Specifically, in this chapter, we present a framework focused on the monitoring and assistance of the elderly that are living alone, focusing on those elderly with memory disabilities. We believe that this approach will enable the challenges that the current trend of population aging poses to be tackled. © 2015 by Taylor & Francis Group, LLC.
