In this paper, a method is presented for lowering the energy consumption and/or increasing the speed of a standard manipulator spray painting a surface. The approach is based on the observation that a small angle between the spray direction and the surface normal does not affect the quality of the paint job. Recent results in set-based kinematic control are utilized to develop a switched contro...

The computer graphic simulation of a common spray painting artifact, called orange peel, is discussed. Orange peel distorts surface reflections and is commonplace in product design applications. The orange peel measurements from a standard industrial instrument are used to construct a height field, and this surface is rendered using traditional normal mapping techniques. Comparisons are made be...

Data from Washington State's work-related asthma surveillance system were used to characterize isocyanate-induced asthma cases occurring from 1999 through 2010. Injured worker interviews and medical records were used to describe the industry, job title, work process, workers' compensation cost, and exposure trends associated with 27 cases of isocyanate-induced asthma. The majority (81%) of case...

It is known that even if process information at macroscale is fully accessible and properly utilized in manufacturing, product and process performance may be still not sufficiently assured. This may be due to the influence of phenomena at finer scales, which are normally not measurable and thus unknown in operation. Besides, even if such information is available, how to integrate it across scal...

In this research, we examined the effect of prediction-observation-explanation (POE) method on learning image formation by a plane mirror and pre-service teachers’ opinions. Twenty science teachers studying at first grade in Department Science Education Turkey participated research. We used one group pretest–posttest design. teaching process, carried out accordance with POE method, made their o...

Diffuse alveolar haemorrhage (DAH) is a clinical syndrome resulting from injury to the alveolar microcirculation, most commonly associated with not only autoimmune disorders or connective tissue disease, but also a variety of infections, neoplasms and toxins. We report here a case of an otherwise healthy young man with DAH attributable to an inhalation injury resulting from use of aerosol spray...
