Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
Various patterns of behavior enable certain ectotherms to regulate body temperature to a useful extent. To warm up, reptiles and many insects find sunny places and adopt positions that maximise their exposure; at harmfully high temperatures they seek shade or cooler water.
The centrifugal governor is an early proportional control mechanism.. A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops.
The Lee–Yang zeros may be connected to the cumulants of the conjugate variable of the control variable . [ 11 ] [ 12 ] For brevity, we set β = 1 {\displaystyle \beta =1} in the following. Using that the partition function is an entire function for a finite-size system, one may expand it in terms of its zeros as
Sociotechnical systems (STS) in organizational development is an approach to complex organizational work design that recognizes the interaction between people and technology in workplaces.
