Practice projectile motion with fully solved physics problem examples. This video walks through step-by-step solutions to help you understand equations, motion components, and problem-solving ...

Abstract: Geometric insight may lead to a quick solution for a class of non-LQ optimal control problems. We illustrate this with a simple, inconspicuous-looking example. While necessary conditions for ...

Air traffic controller staffing shortages worsened over the weekend as the nation’s government shutdown hit its fourth week, leading to delays and anxiety, and experts say it won’t get better until ...

An audit of ambient storage and distribution food business operators in Ireland has revealed pest control problems and a variety of other deficiencies. The Food Safety Authority of Ireland (FSAI) said ...

The Federal Aviation Administration reported 12 of their facilities were short-staffed on Friday, including some which have caused delays for travelers. Phoenix Sky Harbor International airport will ...

Gun control as a solution to spectacular public murders doesn’t stand up to scrutiny. In the aftermath of multiple murderous outrages — political assassinations, school shootings, attacks on law ...

Air travel was supposed to be just one part of Niraj Chokshi’s assignment at The Times. But then the pandemic started a wave of news that hasn’t really stopped. By Terence McGinley Times Insider ...

We numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the non-linear case and ...

Abstract: A novel technique to solve optimal control problems with state constraints is proposed. We exploit the theory of exact penalty functions, used in mathematical programming, to construct a ...
