Increase of the delivered energy probability in DES using a fuzzy probabilistic modeling

The paper proposes a methodology to increase the probability of delivering power to any load point by identifying new investments in distribution energy systems. The proposed methodology is based on statistical failure and repair data of distribution components and it uses a fuzzy-probabilistic modeling for the components outage parameters. The fuzzy membership functions of the outage parameters of each component are based on statistical records. A mixed integer nonlinear programming optimization model is developed in order to identify the adequate investments in distribution energy system components which allow increasing the probability of delivering power to any customer in the distribution system at the minimum possible cost for the system operator. To illustrate the application of the proposed methodology, the paper includes a case study that considers a 180 bus distribution network.

Le moment venu ou l’eveil dês editoriaux. Mutations de la littérature des années quatre-vingt vues par les revues littéraires

Les années quatre-vingt signalent un point de bascule dans et une mutation majeure dans les caractéristiques narratives de la littérature française. D’une certaine façon, elles entament la contemporanéité littéraire telle que nous la connaissons du point de vue critique. Nous insisterons sur le rôle des revues et des éditoriaux dans ce processus. Ils manifestent quelques hésitations de la critique par rapport à la littérature naissante.

Motivations which influence volunteers' satisfaction

In this paper we attempt to find out which motivations influence volunteers satisfaction. So, in a first moment, we categorize satisfaction through a factor analysis and then use linear regression models to find out the relations previously mentioned. Furthermore we analyse the existence of correlations between some demographic attributes and the other variables. In this research the population under study includes volunteers that work in the health area, more precisely volunteers that work in hospital and have direct contact with patients and their families. We obtained a total of 327 questionnaires and after excluding incomplete answers we get 304 questionnaires which embody a response rate of 36%. The outcomes of our analysis reveal that we can categorize satisfaction into intrinsic and extrinsic categories and show that motivations related to belonging and protection and career recognition are the ones influencing extrinsic satisfaction; motivations associated to development and learning and altruism are the ones with higher effect in intrinsic satisfaction. There are some negative correlations between age and extrinsic satisfaction, between years of participation and extrinsic satisfaction, between education and the motivation related to belonging and protection and between age and the motivation related to career recognition. There is only one positive correlation between hours per week and intrinsic satisfaction. The results offer new insights for research about volunteers’ motivations, motive fulfillment and volunteer satisfaction. Furthermore the outcomes advocate that to ensure satisfied volunteers, their motivations must be identified in a timely and appropriate moment, meaning that should happened as early as possible.

Organisational influence on volunteer satisfaction and attitudes towards HRM practices: the case of hospital volunteers

We examine volunteer satisfaction with HRM practices, namely recruitment, training and reward in NPOs and attitudes regarding the appropriateness of these practices. The participants in this study are 76 volunteers affiliated with four different NPOs, who work in hospitals and have direct contact with patients and their families. Analysing aggregate results we show that volunteers are more satisfied with training, and consider the training strategies to be very appropriate. After identifying differences between organisations we discover that in some organisations volunteers are satisfied with rewards but they have negative attitudes regarding the appropriateness of the recognition strategies. We also identify the volunteers who are the most and the least satisfied.

Learner’s satisfaction within a breast imaging eLearning course for radiographers

Background: An asynchronous eLearning system was developed for radiographers in order to promote a better knowledge about senology and mammography. Objectives: to assess the learners’ satisfaction. Methods: Target population included radiographers and radiogr aphy students, in order to assess eLearning satisfaction according to different experience levels in breast imaging. Satisfaction was measured through a questionnaire developed especially for eLearning systems, using a seven - point Likert scale. Main topics related are content, interface, personalization and learning community. Results: Overall, 85% of learners were satisfied with the course and 87,5% considered that the course is successful. Main areas that were evaluated by most learners in a positive way were interface and content (between six and seven - point); on the other hand, learning community presented a wider distribution of answers . Conclusions: The course provides an overall high degree of learner satisfaction, thus providing more effective knowle dge gain on breast imaging for radiographers.

Interface IP-KNX para um sistema de controlo domótico

São vários os factores sociais e económicos que valorizam a aplicação de tecnologias de domótica em edifícios. No caso particular dos edifícios residenciais, a tendência dos seus utilizadores é a instalação de sistemas de controlo da segurança, do ambiente, de mecanismos de rega e de alarmes. Assim, seguindo a premissa do marketing, que identifica como uma boa prática a projecção de produtos / serviços que satisfaçam as necessidades inventariadas pelos seus utilizadores, este trabalho assenta na criação de um sistema domótico, controlado remotamente através de uma aplicação Android, que pretende, numa primeira instância, o controlo das lâmpadas de uma habitação. Neste trabalho é utilizado o protocolo KNX.TP para a comunicação dos dispositivos de domótica existentes no ISEP, que constituem o ambiente domótico deste trabalho. De forma a implementar o controlo remoto destes dispositivos via internet, este trabalho foca-se no desenvolvimento de uma interface IP-KNX, usando como hardware de controlo, um Arduino Mega 2560, uma placa de interface Ethernet para Arduino, a placa de integração KNX, e um servidor web com a linguagem PHP instalada. Para efeitos de demonstração, foi criada uma aplicação para o SO Android que controla as lâmpadas da rede KNX. Neste trabalho foram utilizadas várias linguagens de programação: C++ no firmware do Arduino, PHP no servidor web e JAVA + XML na aplicação Android.

Veículo ZEV (sem emissões)

A crescente dependência energética do Petr óleo e o impacto ambiental daí resultante, tanto como as excessivas autonomias e desempenho dos veículos perante as nossas necessidades, leva a que Portugal, a Europa, o Mundo, necessitem de apostar em inovar e alterar costumes, de forma a que o nosso planeta se mantenha sustentável e de maneira a aumentar a qualidade de vida de todos nós. As emissões proveniente dos veículos representam uma excessiva parcela na poluição atmosférica causada pela queima dos derivados do petróleo. Uma das soluções mais viáveis para a redução de emissões, passaria pela implementação de leis que fomentassem a compra dos veículos ZEV. Este trabalho pretende provar a inviabilidade do uso contínuo de combustíveis fósseis, destaca as principais características dos veículos eléctricos e os benefícios destes quando comparados com os veículos convencionais, descreve as características dos veículos eléctricos comercializados em Portugal e apresenta a sugestão, com base no estudo elaborado, de um veículo ZEV que se adapte às necessidades do cidadão europeu.

Satisfaction towards human resources practices and repatriates’ retention: an empirical examination in the portuguese companies context

This paper examines the relationship between the level of satisfaction towards Human Resources Management practices among repatriates and the decision to remain on the home company after expatriation. Data was collected through semi-structured interviews of 28 Portuguese repatriates who remain and 16 organisational representatives from eight companies located in Portugal. The results show that (1) compensation system during the international assignment; (2) permanent support during the international assignment and; (3) recognition upon the return of the work and effort of expatriates during the international assignment are the most important HRM practices for promoting satisfaction among repatriates. Moreover, it is at repatriation phase that repatriates show higher dissatisfaction with HRM support. These findings will be discussed in detail and implications and suggestions for future research will be proposed as well.
