This paper describes a device speci®cally designed to facilitate neonatal sweat testing. The components are sized appropriately for attachment to the limbs of newborns. Iontophoretic electrodes, with pilocarpine gel inserts, are latched into small holders attached by straps to the limb. The holder at the anodic site remains in place to receive and align the sensor cell, which uses a conical col...

Several recent demonstrations of the abilities of micro-electromechanical systems (MEMS)-based microsensor technology to detect hazardous ompounds and their simulants in a variety of background conditions are presented. In each case, two pairs of conductometric metal oxide sensors TiO2 and SnO2) produced via chemical vapor deposition are operated using temperature-programmed sensing (TPS). NIST...

A general-purpose microcomputer was used to au tomate the determination of lead conductance value by titration. The microcumputer, presented with an extracted sample in a beaker, controls the addition of titrant and the taking of data, performs all calculations, and finally prints the corrected result along with a record of the titration. A number of operating parameters were studied in order t...

A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...

in this research work, alpha particle detector is made using semi-insulating gaas. a surface barrier detector with a semi-insulating gaas substrate at room temperature with pressure of 10-4 torr under -particle radiation with 5.48 mev of am241 source, have been under investigation. energy resolution of 2 and 3 mm schottky diameter have been matured and compared with the effect of voltage varia...
