A Platform to Emulate Ambient Assisted Living Environments

According to the opinion of clinicians, emerging medical conditions can be timely detected by observing changes in the activities of daily living and/or in the physiological signals of a person. To accomplish such purpose, it is necessary to properly monitor both the person’s physiological signals as well as the home environment with sensing technology. Wireless sensor networks (WSNs) are a promising technology for this support. After receiving the data from the sensor nodes, a computer processes the data and extracts information to detect any abnormality. The computer runs algorithms that should have been previously developed and tested in real homes or in living-labs. However, these installations (and volunteers) may not be easily available. In order to get around that difficulty, this paper suggests the making of a physical model to emulate basic actions of a user at home, thus giving autonomy to researchers wanting to test the performance of their algorithms. This paper also studies some data communication issues in mobile WSNs namely how the orientation of the sensor nodes in the body affects the received signal strength, as well as retransmission aspects of a TDMA-based MAC protocol in the data recovery process.

PROGRAMA PARA A JUSTIÇA PORTUGUESA

Há a verdade, há a mentira e há as estatísticas. Muitas outras medidas poderiam ser alvitradas, mas estas são algumas das ideias fundamentais para um programa de Governo que visa uma Justiça humanista, na qual o Ser Humano, organizado ou individual, é o centro da questão. A Justiça portuguesa também não pode ser uma competição entre a cor-de-laranja e o rosa, vermelho, azul ou qualquer outra cor, como amarelo, cinzento, castanho, entre outras. A Justiça portuguesa deve fazer-se sentir e respeitar. Não é mentira se dissermos que temos entre os melhores Magistrados do mundo, entre os melhores Advogados e Solicitadores do mundo, entre os melhores Funcionários Judiciais, Conservadores, Notários e outros Auxiliares de Justiça, entre os melhores polícias e investigadores do mundo. Bem hajas, Portugal, pois és capaz de muito mais e melhor. § There is the fact there are lies and there are statistics. Many other measures could be tell, but these are some of the key ideas for a government program aimed at a humanistic Justice, in which the human being organized or individual, is the heart of the matter. The Portuguese Justice can not be a competition between the pink-orange and pink, red, blue or any other color, such as yellow, gray, brown, and others. The Portuguese Justice must be felt and respect. It's not a lie if we say we have among the best Magistrates of the world, among the best Lawyers and Solicitors of the world, among the best Judicial Officers, Conservatives, notaries and other auxiliaries of Justice, police and among the best researchers in the world. Well wilt, Portugal, for you are capable of much more and better.
