Abstract: This paper studied a novel parallel machine rescheduling problem with controllable processing times under machine breakdown and precedence constraints. This problem is strongly $\mathcal {NP ...

A right triangular plate scaled by a factor two generates a bigger plate composed of four triangular plates the same size as the original. By using dimensional analysis we write the moment of inertia ...

This is an updated version of a story first published on May 5, 2024. For many high school students returning to class, it may seem like geometry and trigonometry were created by the Greeks as a form ...

A high school teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students. Then Calcea Johnson and Ne'Kiya Jackson stepped up to the challenge.

When using the Z3 solver, I've noticed that despite enabling parallel mode (set_param("parallel.enable", True)), the actual solving process doesn't seem to fully utilize multi-threading. I've observed ...

Where were you on that day in March 2020 when the COVID-19 pandemic shut the world down? How did you spend your year in quarantine? When did you realize the world and life as you knew it — your little ...

Neelkanth Mishra, Chief Economist of Axis Bank, says the Reserve Bank of India's policy to stabilize the rupee has lasted longer than necessary and has resulted in a weakening of the currency.

Calcea Johnson (right), currently studying environmental engineering at Louisiana State University, published the new study with her high school classmate, Ne'Kiya Jackson (left), now a student in ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school. When you ...
