Codificação para o Canal Gaussiano de Múltiplo Acesso

In this paper we propose a coding strategy for the two-user Gaussian Multiple Access Channel. We are interested in the problem from the point of view of the detection of the first user, which will treat the signals from the other user as noise. This strategy is known as Successive Interference Cancellation (SIC). Our coding scheme is based on the Low Density Parity Check (LDPC) codes. On detect...

Head positioning for anterior circulation aneurysms microsurgery Posicionamento da cabeça para microcirurgias de aneurismas da circulação anterior

Objective: To study the ideal patient’s head positioning for the anterior circulation aneurysms microsurgery. Method: We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the ...

Indicadores Para Avaliação Do Acesso Vascular De Usuários Em Hemodiálise Indicadores Para Evaluación Del Acceso Vascular De Pacientes En Hemodiálisis

The purpose of this study was to develop reliable assessment instruments to measure hemodialysis vascular access. The design of healthcare indicators involved an in-depthanalysis of vascular access practices in hemodialysis and their underlying theoretical rationale, and was grounded on Donabedian's framework. Four indicators were selected: performance of temporary double-lumen catheter, mainte...

Adoção da Metodologia Extreme Programming para Construção de Sofware

This paper deals with the possible use and adoption of the methodology Extreme Programming (XP) in the development of free software communities for developers. As each day comes new communities of free software and this type of development is becoming increasingly popular, feel free to look better if this code developed collectively and consequently its quality. The aim is that as a result this...
