Wood mask of flat triangular form with a disk superstructure on top of two curved columns. The bottom triangular form is painted in dark brown with bands of semicircles within semicircles in white, ...

A neural network (NN) adaptive control design problem is addressed for a class of uncertain multi-input-multi-output (MIMO) nonlinear systems in block-triangular form. The considered systems contain ...

This book focuses on mesh (grid) enhancement techniques — specifically, the use of selected elliptic methods for both structured and unstructured meshes associated with computational physics ...

Abstract Let UTn(F) UT n (𝔽) be the semigroup of all upper triangular n× n n × n matrices over a field F 𝔽 whose main diagonal entries are 0 0 s and/or 1 1 s. Volkov proved that UT3(R) UT 3 (ℝ) is ...
