An analysis of human motor control during bipedal walking with passive knee orthoses
The muscle-tendon units of human beings are helpful for minimizing the energy costs during walking. Therefore, proper use of characteristics of these units is effective for walking support and performance improvement.

Granular Crystals: Controlling Mechanical Energy with Nonlinearity and Discreteness [PDF]
The presence of structural discreteness and periodicity can affect the propagation of phonons, sound, and other mechanical waves. A fundamental property of many of the periodic structures and materials designed for this purpose is the presence of ...

Influence of Humidity on the Energy of Specific Strain in the Process of Loading Sedimentary Rocks
This article presents the results of tests on the energy properties of sedimentary rocks in the Upper Silesian Coal Basin. The rocks were tested both in an air-dry state and in a water saturation state.

Estimating the rockburst hazard of hard rocks based on laboratory test results
The relevance of the problem under study is based on the fact that dynamic fractures of mine workings occur in rock masses when developing mineral deposits. Safety assurance of mining depends on the awareness of proneness of various rock types to brittle

Energy Propagation in a Cauchy Elastic Material [PDF]
It has been shown by Schouten [1] that in an anisotropic homogeneous elastic material subjected to infinitesimal deformations the energy propagation vector is necessarily normal to the slowness surface. It can be readily shown (see, for example, [2]) that the bicharacteristics are also normal to the slowness surface.

Variation of Elastic Energy Shows Reliable Signal of Upcoming Catastrophic Failure
We consider the Equal-Load-Sharing Fiber Bundle Model as a model for composite materials under stress and derive elastic energy and damage energy as a function of strain.
