The control of cell division by tension or diffusion
Nature, 1978SEVERAL types of experiment which have been interpreted as evidence for the control of cell division by the action of diffusion boundary layers can equally well be interpreted as being due to the action of mechanical effects. The pumping experiment, and wounding experiments1 have all been interpreted as evidence that increasing the rate of exchange of ...

Biofeedback, self-control and tension headache
Journal of Psychosomatic Research, 1985This research tested the belief that muscle contractions are a primary source of tension headache. EMG level was found to be associated with both headache-specific and more global symptoms following biofeedback training. However, the level of pretreatment relationship between EMG level and headache symptoms was weak, and the amount of reduction in EMG ...

Inhibition of Tension Vibration for Winding Tension Control System
2018 37th Chinese Control Conference (CCC), 2018Aimed at the tension vibration of the winding tension control system, this paper study control strategy of inhibiting it. A dual-motor driven winding control system model is constructed. The causes of tension vibration are analyzed. The control strategy of fuzzy adaptive control to inhibit the tension vibration is proposed, and the fuzzy controller is ...

Local control of bias and tension in beta-splines
Proceedings of the 10th annual conference on Computer graphics and interactive techniques, 1983The Beta-spline introduced recently by Barsky is a generalization of the uniform cubic B-spline: parametric discontinuities are introduced in such a way as to preserve continuity of the unit tangent and curvature vectors at joints ( geometric continuity ) while providing bias and tension parameters, independent of ...

Relaxation and Neuromuscular Tension Control and Changes in Motor Performance under Induced Tension
Perceptual and Motor Skills, 1972The purpose of this study was to determine the effects of specific instructions in relaxation and neuromuscular tension control on changes in the performance of a motor test under stress. The motor test was throwing darts at a specific target for speed and accuracy. Stress was induced by a verbal threat of failure.

Tension controller design for unwinding tension system based on active disturbance rejection control
2012 IEEE International Conference on Mechatronics and Automation, 2012A unique controller based on active disturbance rejection control (ADRC) method is presented to strengthen the stability of the tension in unwinding system of gravure printing machines. The uniqueness of the ADRC design is that both the internal dynamics and the external disturbances can be actively estimated and compensated in real time, which makes ...

Design and control of multi-span tension simulator
Conference Record of the 1999 IEEE Industry Applications Conference. Thirty-Forth IAS Annual Meeting (Cat. No.99CH36370), 1999In this paper, the design and control aspects of a multispan tension simulator are presented. The simulator consists of four driven rolls, including unwinder, winder, and two bridle rolls. Some relationships between design parameters and characteristics of the simulator are explained as a design guide of a multispan system.

A shape preserving interpolant with tension controls
Computer Aided Geometric Design, 1988Shape-preserving interpolation with tension controls is studied. In the one-variable setting, a weighted least-squares minimization model is used with weights controlling the shapes of the curve. By forcing a spline model, the resulting model is a constrained quadratic programming problem.

A Design for Spinning Tension Control
Journal of Engineering for Industry, 1985A new cap-spinning design is described. A unique feature enables the cap to be operated at different speeds from the bobbin to increase or decrease yarn tension as needed. The new spinner will operate as a modification on a conventional ring spinning frame. However, it eliminates the need for rings and travelers. Due to the spinners independent tension
