Subcutaneous Abscess Secondary to Xanthogranulomatous Cholecystitis
Correia, Hugo; Serviço de Imagiologia. Centro Hospitalar Tondela-Viseu. Viseu. Portugal.One of the known complications of gallstones consists in gallbladder perforation with cholecystocutaneous abscesses or external fistulas formation. Nowadays these types of complications are uncommon, having been more frequent. The authors report the case of an 86 year-old woman, bedridden and dependent, referred to our institution by presenting a tumefaction with inflammatory signs in the right upper quadrant. ...

Compositional abstraction of CSP Z processes
Farias,Adalberto; Mota,Alexandre; Sampaio,AugustoData abstraction is a powerful technique to overcome state explosion in model checking. For CSP Z (a formal integration of the well-known specification languages CSP and Z), current approaches can mechanically abstract infinite domains (types) as long as they are not used in communications. This work presents a compositional and systematic approach to data abstract CSP Z specifications even when communications ...
Using CAN to retrofit houses for quadriplegic people
Fonseca, José; Bartolomeu, Paulo; Silva, Valter; Santos, Vasco; Abreu, Carlos; Mota, Alexandre; Cunha, Margarida; Lopes, ArmindaThis paper describes the B-Live® system targetted to automate house appliances for severely impaired people, in particular quadriplegic. This system has been developed at Micro I/O for enhancing the quality of life and the independence of its potential users. The envisaged application is the retrofitting of common dwellings. The B-Live system is described and details on its software, hardware and CAN-based comm...

Automating Home Appliances For Elderly and Impaired People: The B-Live Approach
Bartolomeu, Paulo; Fonseca, José; Santos, Vasco; Mota, Alexandre; Silva, Valter; Sizenando, MargaridaThis paper describes the B-Live approach for automating home appliances for elderly and impaired people. This system has been developed at Micro I/O for enhancing the quality of life and the independence of its potential users. The target application is the retrofitting of common dwellings. The paper introduces the motivation for the B-Live system and presents a survey on current Smart Home projects and endeavo...

Modelagem de planos de recomposição de sistemas elétricos como grafos CPM/PERT
Mota,Alexandre de Assis; Mota,Lia Toledo Moreira; França,André Luiz MorelatoEsse trabalho formaliza um modelo de grafos CPM/PERT para viabilizar a representação de planos de recomposição de sistemas elétricos e expõe uma metodologia para derivação automática do mesmo a partir da lista de atividades de um procedimento de recomposição. Essa técnica de montagem automática foi aplicada com sucesso a uma instrução operativa de recomposição pós-blecautes do sistema interligado nacional (SIN)...
Modelagem e simulação de cargas residencias termostáticas para a recomposição d...
Mota,Lia Toledo Moreira; Mota,Alexandre de Assis; França,André L. MorelatoEste trabalho trata da modelagem da carga no processo de recomposição do sistema de energia elétrica após a ocorrência de blecautes. Em especial, é analisado o comportamento de cargas residenciais termostáticas, que são as principais responsáveis pelo aumento da demanda pós-perturbação, e cujo conhecimento é essencial na recomposição do sistema. A modelagem é construída a partir de técnicas de programação orien...
