Considering water resource scarcity and uncertainty in climate and demand futures, decision-makers require techniques for sustainability analysis in resource management. Through unclear definitions of “sustainability”, however, traditional indices for resource evaluation propose options of limited flexibility by adopting static climate and demand scenarios, limiting analysis variables to a part...

exposure to vibration is the cause of some occupational injuries and diseases. objective of this study was determination of vibration exposure of tractor drivers and assessment of musculoskeletal disorder . this cross-sectional and descriptive- analytical study was administrated to 95 tractor drivers to census method and measuring induced vibration to the drivers was done in three axis, x, y, a...

This paper presents a detailed analysis of the QR-RLS algorithm in infinite precision, when the input signal samples are not correlated. Equations for the dynamic range of the algorithm are derived.

The regulation of water loss through the skin is a poorly understood but crucial process in maintaining terrestrial life-forms. In mammalian skin, the outermost layer, called the stratum corneum (SC), is rate-limiting to water loss. We have evaluated temperature-dependent changes in water vapor permeability and infrared spectra of porcine SC. In particular, we have analyzed the infrared absorpt...
