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.

Physiotherapy for Tension-Type Headache: A Controlled Study
Cephalalgia, 2004The role of non-pharmacological therapies in the preventive treatment of tension-type headache (TTH) is still an object of debate. The primary aim of this study was therefore to investigate the therapeutic effect of physiotherapy in properly classified patients with TTH in a controlled trial.

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 ...

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.

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.

Manufacturing Science and Engineering, 1999
Abstract This paper analyzes the current coil-winding machine to determine the wire tension occurring at various locations along the winding apparatus. The goal is to make possible design improvements for better wire tension control at the armature to prevent wire breakage and to enable high-speed winding.

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

Behavioral Control of Tension Headaches
1981Headache pain is a widely reported physical complaint. Survey data indicates that up to 65% of nonclinical populations report periodic headaches (20). The majority of headaches can be classified as tension or migraine varieties, with tension headaches accounting for up to 80% of headaches (1). The purpose of this chapter is to present research relevant

Controls and Tensions in the Soviet System
American Political Science Review, 1950Scholarly analysis of contemporary Soviet realities has faced increasing difficulties in recent years. Direct access to the Soviet Union is denied to all except a handful of diplomats, journalists, and business men on special missions, and even the very few who gain access find themselves largely cut off from all except carefully controlled official ...
