Implementation of fatigue prediction models, such as the Sleep, Activity, Fatigue, and Task Effectiveness model, optimize scheduling by being able to predict pilot fatigue at any point in time. Although the mathematical model is limited by individual pilot differences it is the most accurate existing prediction because it takes into account ...
v. t. e. In political science, voter fatigue is a cause of voter abstention which result from the electorates of representative democracies being asked to vote often, on too many issues or without easy access to relevant information. [1] Voter fatigue can be a symptom of efforts that make voting more difficult that some describe as voter ...
Fatigue duty. German prisoners in Britain on fatigue duty during World War I. Fatigue duty (or fatigue labor) is the labor assigned to military men that does not require the use of armament. [1] [2] Parties sent on fatigue duty were known in English by the French term "en détachement" according to an 1805 military dictionary. [3]
The bright area is caused by sudden fracture. In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface.
A time and motion study (or time-motion study) is a business efficiency technique combining the Time Study work of Frederick Winslow Taylor with the Motion Study work of Frank and Lillian Gilbreth (the same couple as is best known through the biographical 1950 film and book Cheaper by the Dozen ). It is a major part of scientific management ...
Media fatigue is psychological exhaustion due to information overload from any form of media, though it is generally from news media [1] and social media. [2] The advent of the internet has contributed widely to media fatigue with vast amounts of information easily accessible and easily disseminated. Psychological exhaustion caused by media ...
Effects of fatigue on safety. [1] Fatigue is a major safety concern in many fields, but especially in transportation, because fatigue can result in disastrous accidents. Fatigue is considered an internal precondition for unsafe acts because it negatively affects the human operator's internal state.
Low cycle fatigue (LCF) has two fundamental characteristics: plastic deformation in each cycle; and low cycle phenomenon, in which the materials have finite endurance for this type of load. The term cycle refers to repeated applications of stress that lead to eventual fatigue and failure; low-cycle pertains to a long period between applications.
