Bio-Mechanics : Biomechanics is mechanics applied to biology. This includes research and analysis of the mechanics of living organisms and the application of engineering principles to and from biological systems. This research and analysis can be carried forth on multiple levels, from the molecular, wherein biomaterials such as collagen and elastin are considered, all the way up to the tissue and organ level. Some simple applications of Newtonian mechanics can supply correct approximations on each level, but precise details demand the use of continuum mechanics.
FAQ : FAQ is an acronym for "Frequently Asked Question(s)." The term refers to listed questions and answers, all supposed to be frequently asked in some context, and pertaining to a particular topic. Since the acronym originated in textual media, its pronunciation varies; "fak", "faks" and "F.A.Q." are commonly heard. Depending on usage, the term may refer specifically to a single frequently asked question, or to an assembled list of many questions and their answers.
FPS : A first-person shooter is an action video game from the shooter game subgenre. Like all shooters, they involve "an avatar, one or more ranged weapons, and a varying number of enemies." FPSs are distinguished by a first person perspective, that renders the game world from the visual perspective of the player character.
MMORPG : Massively multiplayer online role-playing game is a genre of massively multiplayer online computer role-playing games (CRPGs) in which a large number of players interact with one another in a virtual world.
Megawatt (MW) : The megawatt (symbol: MW) is equal to one million (106) watts.
Orthopedics : Orthopedic surgery or orthopedics is the branch of surgery concerned with acute, chronic, traumatic, and overuse injuries and other disorders of the musculoskeletal system. Orthopedic surgeons address most musculoskeletal ailments including arthritis, trauma and congenital deformities using both surgical and non-surgical means. Nicholas Andry coined the word "orthopaedics," derived from Greek words for "correct" or "straight" ("orthos") and "child" ("paidion"), in 1741, when at the age of 81 he published Orthopaedia: or the Art of Correcting and Preventing Deformities in Children.
Recycling : Recycling is the reprocessing of old materials into new products, with the aims of preventing the waste of potentially useful materials, reducing the consumption of fresh raw materials, reducing energy usage, reducing air (from incineration) and water (from landfilling) pollution by reducing the need for "conventional" waste disposal, and lowering greenhouse gas emissions as compared to virgin production. Recycling is a key concept of modern waste management and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy, though colloquial usage of "recycling" can also include "reuse."
Robot : A robot is a mechanical or virtual, artificial agent. It is usually an electromechanical system, which, by its appearance or movements, conveys a sense that it has intent or agency of its own. While there is still discussion about which machines qualify as robots, a typical robot will have several, though not necessarily all of the following properties:
• is not 'natural' i.e. artificially created
• can sense its environment, and manipulate or interact with things in it
• has some ability to make choices based on the environment, often using automatic control or a preprogrammed sequence
• is programmable
• moves with one or more axes of rotation or translation
• makes dexterous co-ordinated movements
• appears to have intent or agency
Six degrees of freedom : Six degrees of freedom (6DoF) refers to motion in three dimensional space, namely the ability to move forward/backward, up/down, left/right (translation in three perpendicular axes) combined with rotation about three perpendicular axes (yaw, pitch, roll). As the movement along each of the three axes is independent of each other and independent of the rotation about any of these axes, the motion indeed has six degrees of freedom. Robots are often categorized by their degrees of freedom (typically achieving more than six degrees of freedom). This number typically refers to the number of single-axis rotational joints in the arm, where a higher number indicates an increased flexibility in positioning a tool. This is a practical metric, in contrast to the abstract definition of degrees of freedom which measures the aggregate positioning capability of a system.
Stewart platform : A Stewart Platform or Hexapod is a kind of parallel manipulator using an octahedral assembly of struts. A Stewart platform has six degrees of freedom (x, y, z, pitch, roll, & yaw).There are six independently actuated legs, where the lengths of the legs are changed to position and orient the platform. The forward kinematics problem, a system of equations which given the leg lengths, yields the position and orientation of the platform, has up to 40 solutions. However, the inverse kinematics problem (i.e. given the position and orientation of the platform, find the required leg lengths) has a unique and very simple solution.
WaterJet :A water jet cutter is a tool capable of slicing into metal or other materials using a jet of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process is essentially the same as water erosion found in nature but accelerated and concentrated by orders of magnitude. It is often used during fabrication or manufacture of parts for machinery and other devices. It has found applications in a diverse number of industries from mining to aerospace where it is used for operations such as cutting, shaping, carving, and reaming.
Wind Power : Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. In windmills, wind energy is directly used to crush grain or to pump water. At the end of 2007, worldwide capacity of wind-powered generators was 94.1 gigawatts. Although wind currently produces just over 1% of world-wide electricity use, it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data). Globally, wind power generation increased more than fivefold between 2000 and 2007.
Wind Turbine : A wind turbine is a rotating machine that converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind turbine, wind power unit (WPU) or wind energy converter (WEC).
