In physics, the degrees of freedom (DOF) of a mechanical system is the number of independent parameters that define its configuration or state. It is important in the analysis of systems of bodies in mechanical engineering , structural engineering , aerospace engineering , robotics , and other fields.
The DOF beyond the subject is always greater than the DOF in front of the subject. When the subject is at the hyperfocal distance or beyond, the far DOF is infinite, so the ratio is 1:∞; as the subject distance decreases, near:far DOF ratio increases, approaching unity at high magnification. For large apertures at typical portrait distances ...
In many scientific fields, the degrees of freedom of a system is the number of parameters of the system that may vary independently. For example, a point in the plane has two degrees of freedom for translation: its two coordinates; a non-infinitesimal object on the plane might have additional degrees of freedoms related to its orientation.
By the equipartition theorem, internal energy per mole of gas equals c v T, where T is absolute temperature and the specific heat at constant volume is c v = (f)(R/2). R = 8.314 J/(K mol) is the universal gas constant, and "f" is the number of thermodynamic (quadratic) degrees of freedom, counting the number of ways in which energy can occur.
DOF ASA, company; DOF Subsea, company; Documento de Origem Florestal (Forest Origin Document), a governmental Brazilian system to regulation of extraction, transport and commerce of native forest products. Double old fashioned glass, a glass for serving "lowball" cocktails that is typically 12-16 fluid ounces (350-470ml)
The New York City Department of Finance (DOF) is the revenue service, taxation agency and recorder of deeds of the government of New York City. [2] Its Parking Violations Bureau is an administrative court that adjudicates parking violations, while its Sheriff's Office is the city's primary civil law enforcement agency.
The six degrees of freedom: forward/back, up/down, left/right, yaw, pitch, roll. Six degrees of freedom (6DOF), or sometimes six degrees of movement, refers to the six mechanical degrees of freedom of movement of a rigid body in three-dimensional space.
DOF ASA was the parent company of the DOF Group, a Norwegian supply shipping company.DOF ASA underwent a bankruptcy process in the Norwegian courts in 2023 and on the 25th of May 2023, a new parent company DOF Group ASA was established and the company continues to operate as an integrated offshore services supplier with global operations.
