Handheld dynamometry (HHD) is a promising tool for obtaining reliable hip strength measurements in the clinical setting, but intertester reliability has been questioned, especially in situations where testers exhibit differences in upper-extremity muscle strength (male vs female). The purpose of this study was to examine the intertester reliability(More)
The Joint Systems Baseline Assessment (JSBA) program is currently planning operational demonstrations of a selected set of joint and coalition intelligence and collection management systems to be performed in early fall of 2006. The Naval Postgraduate School (NPS) is applying a system of systems engineering methodology (Osmundson and Huynh 2005) to the(More)
A computational model of Standing Joint Force Headquarters (SJFHQ) processes was developed using EXTEND simulation software. In this paper we describe the use of this modeling and simulation approach for analyzing time-critical information systems and performing trade studies. An object-oriented model was constructed of the processes performed by SJFHQ(More)
This technical paper presents the results from tests conducted with the ES-2re, a version of the ES-2 side impact dummy that was modified by the National Highway Traffic Safety Administration (NHTSA) to improve its performance in crash tests. Through the series of biofidelity tests conducted on the ES-2re, described in International Standards Organization(More)
A BioRID II dummy and a Hybrid III dummy, each representative of a midsize adult male, were tested side-by-side in simulated rear-impact sled tests. In all tests the dummies were restrained by 3-point belt systems. The results of 4 test sets conducted at a nominal change in velocity (deltaV) of 16 km/hr are presented and discussed. In three of the test(More)
A comparison of the Q3 and Hybrid III 3-year-old crash test dummies is presented in this paper. The performance of the dummies were compared in sixty biofidelity tests, seventy-seven static out-of-position airbag tests and sixty-three calibration tests. Various time histories and other data pertaining to accelerations, deflections, forces and moments are(More)
