This paper exhibits the first parallel sort algorithm for shared memory MIMD multiprocessors which has a theoretical and measured speedup near linear. The algorithm is based on a new asynchronous parallel merge which evenly partitions data to be merged between any number of processors. The merge of data sets @ and 63 on p processors has a time complexity of(More)
The Prism simulation system models the interaction of application, system and architectural structures for shared memory multiprocessors and distributed memory multicomputers. The simulation is achieved using two major components, a compiler and a library of processor and architecture modeling routines. The compiler processes application and system code(More)
The purpose of this study was to determine normal, mean quadriceps angles (Q angles) for college-aged men and women, and to compare Q angles measured in the supine and the standing positions. The Q angles of 269 men and 257 women were measured in both positions by use of a specially modified goniometer. The mean Q angle for men was 12.7 degrees in the(More)
In brief: Thirty-three prepubescent, pubescent, and postpubescent males participated in a nine-week resistive exercise program to test the hypothesis that pubescent males respond better to strength training than older and younger groups do. Before and after the program, the subjects' strength in elbow and knee flexion and extension was tested bilaterally on(More)
OBJECTIVE To determine the comparative rate of resolution of a contusion resulting from mechanical trauma to skeletal muscle, as a function of one of four exercise regimens. DESIGN Randomized control trial. The four exercise regimens were: running with its onset immediately after injury, running with a 72 hr delay after injury, swimming with immediate(More)
Lipoid proteinosis caused specific changes in the brain, larynx, and cervical esophagus of a young adult man. Laryngography clearly depicts the distribution and degree of pharyngeal and laryngeal pathology. Florid calcification, conforming to the classical temporal lobe distribution, is documented by plain films and tomography. The clinical picture and the(More)
