Abstract: For a weakly nonlinear system described by Volterra series, if the nonlinear differential equation (NDE) model of the system is unique, the nonlinear auto-regressive with exogenous input ...

ORIGINAL MATRIX: [ [1.0000, 1.0000, 3.0000] [2.0000, 3.0000, 5.0000] ] RREF: [ [1.0000, 0.0000, 4.0000] [0.0000, 1.0000, -1.0000] ] RESULT: UNIQUE SOLUTION SOLUTION ...

Over the past few years, engineers and material scientists have been trying to devise new optical systems in which light particles (i.e., photons) can move freely and in useful ways, irrespective of ...

Solving an equation means finding the value or values for which the two expressions on each side of the equals sign are equal. One of the most common methods used to solve equations is the balance ...

The internet is torn over an elementary-level math equation which left many scratching their heads. The viral math problem has X users stumped - but the answer comes from lessons learned in fifth or ...

Designing a complex electronic device like a delivery drone involves juggling many choices, such as selecting motors and ...
