Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool , used during prehistory , followed by the control of fire —which in turn contributed to the growth of the human brain and the development of ...
Systems engineering uses a host of tools that include modeling and simulation, requirements analysis, and scheduling to manage complexity. Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles.
The US Navy initiated the Military Manpower versus Hardware (HARDMAN) Methodology in 1977 to address problems with manpower, personnel and training in the service. [7] In 1980, The National Academies of Sciences, Engineering, and Medicine established the Committee on Human Factors, which was later renamed the Committee on Human Systems Integration. [8]
Ubiquitous computing (or "ubicomp") is a concept in software engineering, hardware engineering and computer science where computing is made to appear seamlessly anytime and everywhere. In contrast to desktop computing, ubiquitous computing implies use on any device, in any location, and in any format.
An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR (revolute-spherical-spherical-revolute) spatial four-bar linkage.
Mero architectural systems are the closest example to a modular system in terms of hard products in markets. Weapons platforms, especially in aerospace, tend to be modular systems, wherein the airframe is designed to be upgraded multiple times during its lifetime, without the purchase of a completely new system.
Robot arms, Stewart platforms, and humanoid robotic systems are also examples of spatial mechanisms. Bennett's linkage is an example of a spatial overconstrained mechanism, which is constructed from four hinged joints. The group SE(3) [clarification needed] is six-dimensional, which means the position of a body in space is defined by six ...
