The means whereby animals adapt their locomotor behavior to variation in environmental conditions is an important and neglected problem in the area of motor control. To investigate this problem, young (3-month-old) pigtailed macaques (Macaca nemestrina) were filmed leaping a fixed distance from both rigid and elastic take-off supports. Sixteen of 17 subjects exhibited substantial invariance in ...

[Purpose] The aim of the study was to investigate the effects of external supports on the degree of knee flexion. [Subjects] Twenty volunteers (40 knees) were recruited to the study. [Methods] Active knee flexion was measured using a goniometer with the patient in the supine position. After measuring the knee flexion with the leg naked, the same procedure was repeated after application of an el...

We present the design, implementation, and an evaluation of Elastic Phoenix. Based on the original Phoenix from Stanford, Elastic Phoenix is also a MapReduce implementation for shared-memory systems. The key new feature of Elastic Phoenix is that it supports malleable jobs: the ability add and remove worker processes during the execution of a job. With the original Phoenix, the number of proces...

Free vibration analyses of lattice sandwich beams with general elastic supports have rarely been discussed in this field’s literature. In paper, a unified method is proposed to study the free characteristics under various boundary conditions. The convert three truss cores into an equivalent homogeneous layer and introduce two different types constraint springs simulate support at both ends beam...
