—A fast digital integrator (FDI) with dynamic accuracy and a trigger frequency higher than those of a portable digital integrator (PDI), which is a state-of-the-art instrument for magnetic measurements based on rotating coils, was developed for analyzing superconducting magnets in particle accelerators. Results of static and dynamic metrological(More)
The ironless inductive position sensor can be the ideal candidate for linear position sensing in harsh environment and in the presence of external magnetic fields. Starting from the validated electromagnetic characteristics, this paper presents a model of thermal effects influencing the sensor's position reading and an effective algorithm to compensate(More)
The reliability of wireless communication in a network of mobile wireless robot nodes depends on the received radio signal strength (RSS). When the robot nodes are deployed in hostile environments with ionizing radiations (such as in some scientific facilities), there is a possibility that some electronic components may fail randomly (due to radiation(More)
—The ironless inductive position sensor is a linear position sensing structure, which exhibits intrinsic immunity to external magnetic fields since it is characterized by air-cored windings. This new solution may be of major interest for applications where external magnetic fields can be a source of interference. In this paper, an analytical model of the(More)
Problems inherent in corticosterone radioimmunoassay (RIA) led to consideration of alternative methods. A high-performance liquid chromatography (HPLC) procedure was evaluated that separated and quantitated dichloromethane-extracted corticosterone by reverse-phase chromatography. The results were correlated (r = 0.92) with an RIA procedure. The HPLC(More)
Solid-state extraction of plasma or serum offers significant advantages over traditional liquid-liquid methods in cortisol determinations by liquid chromatography (HPLC). Sample preparation is facilitated and HPLC column contamination is minimized. Extract yield from the solid-state columns is enhanced by sample pretreatment with methanol. Cortisol values(More)
