A microprocessor-controlled rate controller for use in cryopreservation
Cryobiology, 1979The design and operation of a microprocessor-controlled rate controller incorporated into a constant-rate cooling system used in the cryopreservation of cells is described. The controller differs from those currently available in that the actual temperature of the cell suspension being cooled is compared with a preselected ramp of the microprocessor ...

A pragmatic controller for explicit rate congestion control
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002This paper examines congestion control for explicit rate data networks. The available bit rate (ABR) service category of asynchronous transfer mode (ATM) networks serves as an example system for this paper, however the results of this paper are applicable to other explicit rate systems as well.

Heart rate perception and the voluntary control of heart rate
Biological Psychology, 1980Heart rate perception was assessed in two sets of trials by having subjects set an intermittent visual pulse to match their heart rates. Just prior to matching subjects were required to either hyperventilate, hypoventilate or breathe normally to encourage a range of cardiac levels.

Mechanisms in the Control of Speech Rate
Phonetica, 1981Abstract Mechanisms of speech rate control are discussed from the point of view that unidimensional models are inadequate to explain the extensive physiological and acoustical effects observed during changes in speech rate. Evidence is presented to demonstrate that changes in speech rate can result in changes in segmental duration ...

Anxiety, Perception, and Control of Heart Rate
Perceptual and Motor Skills, 19848 women and 8 men took Cattell's IPAT-anxiety questionnaire and later McFarland's test of ability to perceive heart activity. The second test involved subjects' tracking their own heart rates, then they enrolled in an EKG biofeedback session to evaluate ability to increase and decrease heart rate from subjects' resting baselines.

Tracking control of nonlinear systems with bounded controls and control rates
Automatica, 1996Tracking control of nonlinear systems \(\dot x=f(x,u)\), \(y=h(x)\), with \(x\in \mathbb{R}^n\) and \(u,y\in \mathbb{R}^m\) is considered under control constraints and control-rate constraints. A continuous time predictive control approach is proposed provided the system is input-output decouplable and minimum phase.
