Heat treatments are applied to orthodontic wires in order to relieve the stresses arising during orthodontic work. Four types of wires were heated in air, argon or vacuum environments, and cooled in the furnace or in a water bath. The susceptibility to corrosion and mechanical properties of the heat-treated wires were investigated. Heat treatment marginally increased the yield strength and elas...

Raw poultry and poultry products are a significant source of zoonotic bacterial pathogen transmission; thus the sensitive detection of major zoonotic pathogens (Salmonella spp., Campylobacter jejuni, and Listeria monocytogenes) is a vital food safety issue. Recently, third generation PCR technology, known as droplet digital PCR (ddPCR) has been developed to be more accurate and sensitive to det...

Radiometry can be used to correct the wavefront distortions of millimeter and submillimeter signals introduced by the irregular distribution of water vapor in the Earth's troposphere. By measuring the emission due to water vapor along a line of sight it is possible to estimate the corresponding electrical path length. A correction system based on the strong water vapor transition at 183 GHz is ...

Automatic, accurate and online fault detection of heating ventilation air conditioning (HVAC) subsystems, such as chillers, is highly demanded in building management system (BMS) to prevent energy waste and high maintenance cost. However, most fault detection techniques require rich faulty training data which is usually unavailable. In this study, a novel hybrid method is proposed to detect fau...

iDataCool is an HPC architecture jointly developed by the University of Regensburg and the IBM Research and Development Lab Böblingen. It is based on IBM’s iDataPlex platform, whose air-cooling solution was replaced by a custom water-cooling solution that allows for cooling water temperatures of 70◦C/158◦F. The system is coupled to an adsorption chiller by InvenSor that operates efficiently at ...
