Using color for visual recognition outdoors has proven to be a difficult problem, chiefly due to varying illumination. Attempts to classify pixels or image patches in outdoor scenes based on their RGB values often fail, partly because of the inadequacy of the feature set, but partly because of color shifts due to changes in illumination are not well modeled as random noise. Approaches which att...

BACKGROUND The extent to which novel land-efficient neighborhood design can promote key health behaviors is examined, concentrating on communal outdoor space provision (COSP). OBJECTIVES To test whether a neighborhood (Accordia) with a higher ratio of communal to private outdoor space is associated with higher levels of resident's (a) self-reported local health behaviors and (b) observed enga...

Face images obtained by an outdoor surveillance camera, are often confronted with severe degradations (e.g., low-resolution, lowcontrast, blur and noise). This significantly limits the performance of face recognition (FR) systems. This paper presents a framework to overcome the degradation in images obtained by an outdoor surveillance camera, to improve the performance of FR. We have defined a ...

Forty-eight Polish Landrace pigs (initially 32.43 ± 0.70 kg live weight) were assigned to a 2 × 2 × 2 factorial arrangement in order to assess the effects of the rearing system (outdoor v. indoor), diet (with corn grain silage v. without corn grain silage) and gender (barrows v. gilts) on performance, carcass traits, meat quality and intramuscular collagen (IMC) characteristics. During the tria...

BACKGROUND We examined the association between perceived environmental barriers to outdoor mobility and loneliness among community-dwelling older people. In addition, we studied whether walking difficulties and autonomy in participation outdoors affected this association. METHODS Cross-sectional analyses of face-to-face home interview data with 848 people aged 75-90 years (mean age: 80.1 year...

Architects and engineers are beginning to consider a new dimension of indoor air: the structure and composition of airborne microbial communities. A first step in this emerging field is to understand the forces that shape the diversity of bioaerosols across space and time within the built environment. In an effort to elucidate the relative influences of three likely drivers of indoor bioaerosol...

background: human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. materials and methods: an in situ assessment of the indoor and outdoor background radiation in akwanga and keffi towns of nasarawa state nigeria was carried out using a halogen-quenched geiger muller (gm) detector (insp...
