A residential heat detector. A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have ...
In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
Figure 2: [8] Working principle of a thermal laser sensor (Adapted from figure 3 with permission) As shown in Fig 2, a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T 1) being exposed to an absorption area and the other junction type (cold junction at temperature T 2) being exposed to a heat sink.
Industrial and organizational psychology (I-O psychology) "focuses the lens of psychological science on a key aspect of human life, namely, their work lives. In general, the goals of I-O psychology are to better understand and optimize the effectiveness, health, and well-being of both individuals and organizations."
This field utilizes knowledge from several fields such as mechanical engineering, psychology, and industrial engineering [7] to design instruments. Human factors is broader than engineering psychology, which is focused specifically on designing systems that accommodate the information-processing capabilities of the brain.
Morris Simon Viteles (March 21, 1898 - December 7, 1996) [1] was an influential researcher and writer in the field of industrial and organizational psychology.His book Industrial Psychology, published in 1932, was the first comprehensive modern textbook in the field. [2]
For pipelines carrying fluids at temperatures above or below the ambient ground temperatures (i.e., steam, oil, liquefied gases, or chemicals), an alternative is to use the heat sinking ability of the earth to draw heat from the pipeline under test. The crucial point to remember is that the energy must be flowing through the ground and fluids.
Heat and cold stress occur when the temperature is significantly different from room temperature (68-74 degrees Fahrenheit). [30] When the body is exposed to heat stress, excess sweating can lead to a range of heat-related illnesses. [31] Excessive cold can lead to several cold-related illnesses such as hypothermia, frostbite, etc. [32]
