The boundary element method (BEM) based cortical imaging technique (CIT) has been applied to an experimental study on human somatosensory evoked potentials (SEPs) recorded from a patient. The accuracy of the analysis was determined by comparing SEPs recorded from the scalp with those recorded directly from the patient's cortex. The results indicate that the CIT improved the spatial resolution o...

The Boundary Element Method (BEM) is a well-established numerical method for simulation of physical phenomena including structural, fluid flow and heat transfer analysis. It is particularly interesting in electromagnetics because of its handling of open region problems and its accuracy in computing the fields where gradients are high. Classical BEM, however, does not inherently contain a facili...

Resumo. A distribuição das equipes de desenvolvimento tem provocado diversos desafios ao processo de software. Dentre os desafios, a engenharia de requisitos destaca-se, sofrendo impacto de fatores como distância, diferença de cultura e fuso-horário, bem como dos meios de comunicação disponíveis. Nesse contexto, o gerenciamento das informações relacionadas a requisitos torna-se crítico para gar...

Suppression of Multi-User Interference (MUI) and mitigation of timeand frequency-selective (doubly-selective) channel effects constitute major challenges in the design of thirdgeneration wireless mobile systems. Relying on a Basis Expansion Model (BEM) for doubly-selective channels, we develop a channel-independent block spreading scheme that preserves mutual orthogonality among single-cell use...

This article discusses the relations between healthcare systems and the pharmaceutical industry, focusing on state support for pharmaceutical innovation. The study highlights the experiences of the United States, United Kingdom, and Germany, developed countries and paradigms of modern health systems (liberal, universal, and corporatist), in addition to Japan, a case of successful catching up. T...

Tenho o prazer, como Editor da IEEE Transactions on Education, de dar as boasvindas a IEEE-RITA ao portofolio de edições da IEEE Education Society. Nos dois últimos anos, a IEEE Education Society tem vindo a reflectir como poderá dar benefícios adicionais aos seus membros através das suas publicações. Além de IEEE Transactions on Education (periódico do IEEE sobre investigação em educação), The...

INTRODUCTION Anisocorias are a relatively frequent reason for consultation in neuro-ophthalmology units. They remain a diagnostic challenge for specialists as they may be due to several etiological factors. In the absence of other accompanying symptoms, anisocorias are usually due to benign processes. Benign episodic mydriasis (BEM) is an isolated cause of intermittent pupil asymmetry, in which...

A dual boundary integral equation (BIE) formulation is presented for the analysis of general 3-D electrostatic problems, especially those involving thin structures. This dual BIE formulation uses a linear combination of the conventional BIE and hypersingular BIE on the entire boundary of a problem domain. Similar to crack problems in elasticity, the conventional BIE degenerates when the field o...

Boundary-element methods (BEMs) for solving integral equations numerically have been used in many fields to compute the induced charges at dielectric boundaries. In this paper, we consider a more accurate implementation of BEM in the context of ions in aqueous solution near proteins, but our results are applicable more generally. The ions that modulate protein function are often within a few an...
