A high precision alignment system has been developed for online monitoring of the tracking detectors of HERMES. The system consists of a He-Ne laser, Fresnel zone plates, CCD cameras, and electronics to read out the image. It records the alignment information of each detector automatically every 30 minutes during the experiment. The relative detector positions can be monitored with a precision ...

If each off-diagonal entry and the sum of each row of a diagonally dominant M -matrix are known to certain relative accuracy, then its smallest eigenvalue and the entries of its inverse are known to the same order relative accuracy independent of any condition numbers. In this paper, we devise algorithms that compute these quantities with relative errors in the magnitude of the machine precisio...

three rapid, simple, moderately sensitive and selective spectropho-tometric methods are described for the determination of pyrantel pamoate (pyp) in bulk drug and in its pharmaceutical formulations. the methods are based on the reduction of ferric chloride by pyp in neutral medium and subsequent complexation of iron (ii) with ferricyanide (method a), 1, 10-phenanthroline (method b) and 2,2’-bip...

gTOOLS is an open-source software for the processing of relative gravity data. available in MATLAB and as a compiled executable to be run under free Runtime Compiler. The has been designed time-lapse (temporal) monitoring. Although programmed read Scintrex CG-5 CG-6 gravimeters output data files, it can easily modified files from other gravimeters. binds together single-task modules within very...
