The problem of how to train variance parameters on scarce data is addressed in the context of text-dependent, HMM-based, automatic speaker verification. Three variations of variance flooring is explored as a means to prevent over-fitting. With the best performing one, the floor to a variance vector of a client model is proportional to the corresponding variance vector in a non-client multi-spea...

Walkway floors have a significant effect on cattle locomotion and claw health, as well as on animal behaviour and general cattle house hygiene; and affected both animals’ welfare and dairy farmers’ profit. There are several qualities floors should fulfil, which contemporary walkway floors do not completely do. From an animal point of view, the most favourable of present passageway floorings in ...

From its creation to its disposal, there are environmental and health problems associated with polyvinyl chloride (vinyl), the major component of vinyl flooring. The production of vinyl creates toxic waste that must be dumped or incinerated. Because very little vinyl is recycled, the waste material must also be landfilled or burned. Furthermore, the heavy chlorine content of these materials res...

Falling accidents caused by slipping represent a high proportion of all accidents and are cost intensive in industry as well as in the private sphere. To prevent such accidents, the slip resistance of flooring must be evaluated. Therefore, measurement methods are necessary. These methods must provide results that comply with an individual's perception of when a floor is slippery. This article d...

LIFE CERSUDS is a project carried out over the period 2016-2019 whom main objective was to improve ability of cities adapt climate change by promoting use green infrastructures in renewal urban environments. Under project, an innovative permeable pavement (hereinafter, CERSUDS) designed using ceramic tile stock low commercial value. This solution tested demonstrator town Benicí ssim.

Slippery flooring often leads to unintentional slips and falls, which results in traumatic injuries. To reduce slipping risks, adequate traction at the shoe contact is essential. In addition, viscous slippery contaminants like water or oil a floor’s performance increase hazards. this work, effect of commonly available protective floor coatings on safety-labelled shoes was extensively studied. T...

A test chamber method was developed to provide a small and simple emission testing facility capable of testing construction products over a range of climatic parameters, such as temperature, ventilation rate and air velocity, that could be varied independently around typical indoor values. Volatile organic compounds (VOCs), specifically the aromatic hydrocarbons fraction, were measured using a ...

Methods for detecting microorganisms on surfaces are needed to locate biocontamination sources and to relate surface and airborne concentrations. Research was conducted in an experimental room to evaluate surface sampling methods and quantitative PCR (QPCR) for enhanced detection of a target biocontaminant present on flooring materials. QPCR and culture analyses were used to quantitate Bacillus...

Feather pecking and high mortality levels are significant welfare problems in non-cage housing systems for laying hens. The aim of this study was to identify husbandry-related risk factors for feather damage, mortality, and egg laying performance in laying hens housed in the multi-tier non-cage housing systems known as aviaries. Factors tested included type of system flooring, degree of red mit...

This review provides a comprehensive overview of the vascularization of the avian growth plate and its subsequent role in the pathogenesis of bacterial chondronecrosis with osteomyelitis (BCO, femoral head necrosis). BCO sporadically causes high incidences of lameness in rapidly growing broiler (meat-type) chickens. BCO is believed to be initiated by micro-trauma to poorly mineralized columns o...
