LS-DYNA originated from the 3D FEA program DYNA3D, developed by Dr. John O. Hallquist at Lawrence Livermore National Laboratory (LLNL) in 1976. [4] DYNA3D was created in order to simulate the impact of the Full Fuzing Option (FUFO) or "Dial-a-yield" nuclear bomb for low altitude release (impact velocity of ~ 40 m/s).
The earliest units of measure devised by humanity bore no relationship to each other. [citation needed] As both humanity's understanding of philosophical concepts and the organisation of society developed, so units of measurement were standardized—first particular units of measure had the same value across a community, then different units of the same quantity (for example feet and inches ...

Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).
The system + =, + = has exactly one solution: x = 1, y = 2 The nonlinear system + =, + = has the two solutions (x, y) = (1, 0) and (x, y) = (0, 1), while + + =, + + =, + + = has an infinite number of solutions because the third equation is the first equation plus twice the second one and hence contains no independent information; thus any value of z can be chosen and values of x and y can be ...
10. "It's not all about talent. It's about dependability, consistency, and being able to improve. If you work hard and you're coachable, and you understand what you need to do, you can improve."
The case went cold until 2023, when detectives from the police department’s cold case unit reopened the investigation. Investigators used advanced forensic technology to identify Rodgers as the ...
Figure 1: An invariant manifold in the extended phase space, formed by an evolving material surface. On a phase space and over a time interval = [,], consider a non-autonomous dynamical system defined through the flow map : (,,), mapping initial conditions into their position (,,) for any time .
