This paper presents a case-study for the optimization, the monitoring and the automatic control of a refrigeration system in a commercial store. The existing controllers were replaced by Omron temperature controllers, connected to an industrial network and linked to a central computer for data monitoring and temperature control using a LabView software. In case of an alarm occurrence, this syst...

Despite their enhanced marketplace visibility, validity of wearable photoplethysmographic heart rate monitoring is scarce. Forty-seven healthy participants performed seven, 6-min exercise bouts and completed a valid skin type scale. Participants wore an Omron HR500U (OHR) and a Mio Alpha (MA), two commercial wearable photoplethysmographic heart rate monitors. Data were compared to a Polar RS800...

BACKGROUND AND DESIGN This study assesses clinical findings and coexisting dermatological and systemic diseases of Turkish vitiligo patients. MATERIALS AND METHODS One hundred and thirteen patients were included in the study over a 2-year period. Patients were diagnosed by clinical findings and Wood's lamp. Each patient's age, sex, date of onset, first localization, clinical type, disease act...

We discuss scanning electron micrographs and atomic force microscope images of thermally etched GaAs(113) surfaces. The GaAs(113)A and GaAs(113) B surfaces are compared. The polarity of the surface leads to a different morphology for the two surfaces after thermal etching. It is found that the Ga-enriched droplets, which form under As-deficient conditions at higher temperatures, are sitting on ...
