Characterizing, simulating, and eliminating vibration-induced counts in measurement-while-drilling gamma ray detectors
Autor: K. Kimmich, C. Grodsinsky
Publikováno v: Applied Radiation and Isotopes. 48:1385-1390
A measurement-while-drilling (MWD) gamma ray tool will report a higher than actual count rate if its scintillation crystal package produces vibration-induced light pulses. The scintillation crystal is used as a transducer that measures the count rate

Stochastic Model for Microgravity Excitation
Autor: C. Grodsinsky, Joseph Ellison, Goodarz Ahmadi
Publikováno v: Journal of Aerospace Engineering. 8:100-106
A simple stochastic method for generating synthetic orbital accelerations is proposed in this paper. The procedure is used to develop a stochastic model for the STS-40 orbital excitation. The method uses a filtered white-noise model that takes into a

A new approach to controller design for microgravity isolation systems
Autor: Alok Sinha, C.K. Kao, C. Grodsinsky
Publikováno v: Acta Astronautica. 21:771-775
A new method has been developed to design an active vibration isolation system for microgravity space experiments. This method yields the required controller transfer functions for a specified transmissibility. Hence, it is a straightforward task to

The change of gamma equivalent energy with temperature for scintillation detector assemblies
Autor: R. Schreiner, C. Grodsinsky, P. Raby, C. Rozsa, D. Penn
Publikováno v: 1999 IEEE Nuclear Science Symposium. Conference Record. 1999 Nuclear Science Symposium and Medical Imaging Conference (Cat. No.99CH37019).
The change in the relative light output of the alpha and gamma response of scintillators with temperature has been measured. BGO, CaF/sub 2/(Eu), NaI(Tl) and YAP(Ce) were investigated over the temperature range from -20/spl deg/C to 70/spl deg/C. The

Vibration control of equipment aboard spacecraft
Autor: C. Grodsinsky, Joseph Ellison, Goodarz Ahmadi
Publikováno v: Active Materials and Smart Structures.
The performance of various passive and active vibration control devices for equipment aboard spacecraft is analyzed. Several vibration control mechanisms, including pure friction, spring- damper, resilient friction and active friction control systems

The value of endoscopic retrograde cholangiopancreatography in the surgical management of chronic pancreatitis
Autor: D H, Wong, B M, Schuman, C, Grodsinsky
Publikováno v: The American journal of gastroenterology. 73(4)
Sixty-five patients had ERCP for evaluation of chronic pancreatitis. Twenty-six had surgery. Based on surgical and pathological correlation, ERCP was found to be useful in preoperative planning for the type of surgical treatment most appropriate for
