Simulating ubiquitous computing environments
Moreira, SamuelDissertação de mestrado em Engenharia Informática ; Ubiquitous computing (Ubicomp) technologies provide exciting new opportunities for enhancing physical spaces to support the needs and activities of people within them. The ability to develop such systems effectively will offer significant competitive advantage. Tools are required to predict problems related with use early in the design cycle. At the Departmen...
Quantificação volumétrica da hiperplasia neointimal em artérias ilíacas após im...
Moreira,Samuel Martins; Kambara,Antonio Massamitsu; Ajzen,Sergio; Costa Junior,José de RibamarOBJETIVO: Quantificar a hiperplasia neointimal em artérias ilíacas após stent, correlacionando fatores clínicos, arteriais e materiais dos stents. MATERIAIS E MÉTODOS: De junho de 2003 a agosto de 2005, 60 pacientes realizaram angioplastia transluminal percutânea e stent. Desses, 30 foram reestudados com ultrassonografia intravascular. Os dados foram analisados no laboratório de análise quantitativa. RESULTA-DO...
Intestinal obstruction induced by a giant incarcerated Spigelian hernia: case r...
Ribeiro,Edson Augusto; Cruz Junior,Ruy Jorge; Moreira,Samuel MartinsCONTEXT: Spigelian hernia is an uncommon spontaneous lateral ventral hernia with an incarceration ratio of around 20%. However, complications such as intestinal obstruction are extremely rare. We report on a case of giant incarcerated Spigelian hernia with a clinical condition of complete intestinal obstruction that was treated using prosthetic polypropylene mesh. CASE REPORT: A 72-year-old woman was admitted t...

Pedra,Carlos A. C.; Pedra,Simone R. F.; Braga,Sérgio L. N.; Esteves,César A.; Moreira,Samuel M.; Santos,Magali A. dos; Bosisio,Ieda J.OBJECTIVE: To report short and midtem follow-up results of balloon aortic valvuloplasty to treat congenital aortic stenosis. METHODS: Seventy-five patients (median age: 8 years) underwent the procedure through the retrograde femoral or carotid route. RESULTS: The procedure was completed in 74 patients (98.6%). The peak-to-peak systolic gradient dropped from 79.6±27.7 to 22.3±17.8 mmHg (P<0.001), the left ventri...
