Abstract Blind deconvolution techniques applied to spatially and/or temporally oversampled signals have recently attracted much interest in the research community. This contribution contains an analysis of experimental data collected from an antenna array in a suburban environment. The Noise Subspace (NS) technique of [1] and the Linear Prediction (LP) method of [2, 4] are examined. The real da...

OBJECTIVE It has been suggested that level of cognitive functioning as assessed by formal neurocognitive tests may be as important as, or even more important than, symptoms in predicting level of community functioning for patients with schizophrenia. The results of past prospective studies, when carefully examined, do not consistently support this hypothesis. In the current study, the authors u...

BACKGROUND: Randomized clinical trials (RCT) in critical care mostly return negative results. The research community discusses strategies to improve RCTs design. METHODS: This paper presents a theoretical framework based on marginal utility treat the problems of hypothesis generation and treatment effects valuation recently published high-quality studies as instances where such predicts irrelev...

Today, even in the presence of IT applications built for the blind, they are facing many problems. Either the applications are for individual’s use or if offer collaborative writing, they are not up to the mark. In the collaborative writing, for instance, in Microsoft Word Add-In and the Google Docs UI, the authors do not know about changes made in the document. Though the former facilitates th...

The Global Initiative — Vision 2020: The Right to Sight was officially launched on 18 February 1999 with the endorsement of Dr Gro Harlem Brundtland, Director-General, World Health Organization. The mission of Vision 2020 is to eliminate the main causes of blindness in order to give all people of the world, particularly the millions of needlessly blind, the right to sight by the year 2020. In t...

The visual acuities of 1625 individuals recruited to a community-based clinical trial of ivermectin in southern Sierra Leone were measured, and the prevalence of visual loss in this rural population where onchocerciasis is hyperendemic was determined. Ocular examination was performed before treatment to establish the cause of visual loss. Using WHO definitions, 1.3% were blind (less than 3/60 i...

Screen reader technology has appeared first to allow blind and people with reading difficulties to use computer and to access to the digital information. Until now, this technology is exploited mainly to help blind community. During our work with deaf people, we noticed that a screen reader can facilitate the manipulation of computers and the reading of textual information. In this paper, we pr...

Numerous projects have investigated assistive navigation technologies for the blind community, tackling challenges ranging from interface design to sensory substitution. However, none of these have successfully integrated what we consider to be the three factors necessary for a widely deployable system that delivers a rich experience of one’s environment: implementation on a commodity device, u...
