This paper proposes an adaptive Wiener filtering method for speech enhancement. This method depends on the adaptation of the filter transfer function from sample to sample based on the speech signal statistics; the local mean and the local variance.

Air bubble detectors (ABDs) are utilized during cardiopulmonary bypass (CPB) to protect against massive air embolism. Stockert (Munich, Germany) ABD quantify microbubbles >300 μm; however, their reliability has not been reported. The aim of this study was to assess the reliability of the microbubble data from the ABD with the SIII and S5 heart-lung machines. Microbubble counts from the ABD with...

RESUMO Uso o relato de ‘Abd al-Raḥmān al-Baghdādī, imã otomano que visitou Brasil (1866-69), como guia para discutir sua pregação a comunidades afro-muçulmanas no país. Esse relato, conhecido há quase três décadas pela historiografia especializada, proporciona uma visão interna da comunidade africana adepta do Islã oitocentista, com detalhes só superados pelos documentos Revolta dos Malês em 18...

Objective: Acid-base disorders (ABDs) are usually correlated with high rates of morbidity and mortality. The objective of this study was to analyze the causes, outcomes, types and incidences of ABDs in patients presenting at the emergency department (ED). Material and Methods: We prospectively analyzed data from patients who presented between January 2011 and May 2011. Data on age, gender, chie...

We propose a crash safe and pseudo-stabilizing algorithm for implementing an atomic memory abstraction in a message passing system. Our algorithm is particularly appealing for multi-core architectures where both processors and memory contents (including stale messages in transit) are prone to errors and faults. Our algorithm extends the classical fault-tolerant implementation of atomic memory t...
