High-pressure thermoelasticity of body-centered-cubic tantalum [PDF]
Physical Review B, 2002 We have investigated the thermoelasticity of body-centered cubic (bcc) tantalum from first principles by using the linearized augmented plane wave (LAPW) and mixed--basis pseudopotential methods for pressures up to 400 GPa and temperatures up to 10000 K.

Circular Components in Center of Pressure Signals
Motor Control, 2013 Static posturography provides an objective assessment of postural control by characterizing the body sway during upright standing. The center of pressure (COP) signal is recorded by a force platform, and it is analyzed by means of many different models and techniques.

Quantifying center of pressure variability in chondrodystrophoid dogs [PDF]
The Veterinary Journal, 2017 The center of pressure (COP) position reflects a combination of proprioceptive, motor and mechanical function. As such, it can be used to quantify and characterize neurologic dysfunction. The aim of this study was to describe and quantify the movement of COP and its variability in healthy chondrodystrophoid dogs while walking to provide a baseline for ...

Cluster Analysis of Center-of-Pressure Measures [PDF]
International Journal of Electrical and Computer Engineering, 2012 − Postural stability analysis is useful in a variety of applications, such as assessing the risk of falls for older adults or investigating neuromuscular disorders. Variations in the center-of-pressure (COP) are often used to assess postural stability. The COP is a point where the vertical reaction forces of the ground act.
