Noise reduction algorithms in hearing aids are crucial to improve speech understanding in background noise for hearing-impaired persons. For binaural hearing aids multi-microphone algorithms, exploiting signals from both the left and the right hearing aid, are considered to be promising techniques for noise reduction, because in addition to spectral information spatial sound information can be ...

BACKGROUND Outbreaks of hypersensitivity pneumonitis (HP) are not uncommon in workplaces where metal working fluid (MWF) is used to facilitate metal turning. Inhalation of microbe-contaminated MWF has been assumed to be the cause, but previous investigations have failed to establish a spatial relationship between a contaminated source and an outbreak. OBJECTIVES After an outbreak of five case...

In a binaural hearing aid system, output signals for the left and the right ear are generated by exchanging information between the two hearing aids. A significant noise reduction can be achieved using the binaural multi-channel Wiener filter (MWF), which requires all microphone signals from both hearing aids. However, the limited bandwidth of the binaural link typically does not allow to trans...

11 12 The biological treatment of spent synthetic metalworking fluid (MWF) has been investigated in many studies, 13 with most reporting the presence of un-degraded components in the residual waste. In this study, we 14 investigated a hybrid approach to waste treatment of spent MWF, involving both physical treatment and 15 microbial degradation. The effect on biological degradation, of the remo...

Abstract Through their day-to-day usage collaboration tools collect data on the work process. These data can be used to aid participants’ retrospective reflection on the process. The paper shows how this can be done in software development project work. Through a case study we demonstrate how retrospective reflection was conducted by use of an industry approach to project retrospectives combine...

BACKGROUND Increasing evidence suggests that autism is associated with abnormal white-matter (WM) anatomy and impaired brain 'connectivity'. While myelin plays a critical role in synchronized brain communication, its aetiological role in autistic symptoms has only been indirectly addressed by WM volumetric, relaxometry and diffusion tensor imaging studies. A potentially more specific measure of...

The goal of this paper is to examine Wh-islands effects in Bulgarian and Serbo-Croatian (SC) and constructions in which SC must have Wh-movement. The starting point will be Rudin’s (1988) seminal paper on the structure of multiple Wh-fronting (MWF) constructions in Bulgarian and SC. In section 1 of the paper I briefly summarize Rudin’s (1988) analysis as well as a modification of Rudin’s analys...

Mycobacterium immunogenum, a newly identified member of the Mycobacterium chelonae_M. abscessus complex is considered a potential etiological agent for hypersensitivity pneumonitis (HP) in machine workers exposed to contaminated metalworking fluid (MWF). This study investigated the biocidal efficacy of the frequently applied commercial formaldehyde-releasing (HCHO) biocides Grotan and Bioban CS...
