Metroeconomica, Volume 74, Issue 4, Page 658-697, November 2023., 2023 Abstract This paper builds and explores in detail a post‐Keynesian–Sraffian one‐country model of effective demand, which, on the one hand, extends the Kurz multiplier model to open–with state‐economies of single production and, on the other hand, is applicable to data from the National Input–Output Tables of the World Input–Output Database.

International Journal for Numerical Methods in Engineering, Volume 124, Issue 17, Page 3603-3636, 15 September 2023., 2023 Summary A general technique to develop arbitrary‐sided polygonal elements based on the scaled boundary finite element method is presented. Shape functions are derived from the solution of the Poisson's equation in contrast to the well‐known Laplace shape functions that are only linearly complete.

IET Generation, Transmission &Distribution, Volume 16, Issue 15, Page 3050-3068, August 2022., 2022 Abstract Interconnection and expansion of AC networks through high‐voltage direct current grids based on modular multilevel converters to form a multiterminal hybrid AC/DC grid can pose stability issues. These challenges can arise from dynamic interactions between/within AC and DC subgrids due to poorly damped modes that are potential sources of ...

Modal decompositions and point scatterer approximations near the Minnaert resonance frequencies
Studies in Applied Mathematics, Volume 149, Issue 1, Page 164-229, July 2022., 2022 Abstract This paper provides several contributions to the mathematical analysis of subwavelength resonances in a high‐contrast medium containing N$N$ acoustic obstacles. Our approach is based on an exact decomposition formula which reduces the solution of the sound scattering problem to that of an N$N$ dimensional linear system, and characterizes ...

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 The study of convex functions is an interesting area of research due to its huge applications in pure and applied mathematics special in optimization theory. The aim of this paper is to introduce and study a more generalized class of convex functions. We established Schur (S), Hermite‐Hadamard (HH), and Fejér (F) type inequalities for introduced class ...

Optimal Sliding Mode Preview Repetitive Control for Three‐Phase Z‐Source Inverters
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Aiming at high output voltage and obvious current fluctuation of the off grids inverters with unbalanced and nonlinear loads, a compound control strategy of sliding mode controller and optimal preview controller based on Z‐source inverter (ZSI) is proposed.

Doubly periodic lozenge tilings of a hexagon and matrix valued orthogonal polynomials
Studies in Applied Mathematics, Volume 146, Issue 1, Page 3-80, January 2021., 2021 Abstract We analyze a random lozenge tiling model of a large regular hexagon, whose underlying weight structure is periodic of period 2 in both the horizontal and vertical directions. This is a determinantal point process whose correlation kernel is expressed in terms of non‐Hermitian matrix valued orthogonal polynomials (OPs).

Some Bohr‐Type Inequalities for Bounded Analytic Functions
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 In this paper, some new versions of Bohr‐type inequalities with one parameter or involving convex combination for bounded analytic functions of Schwarz function are established. Some previous inequalities are generalized. All the results are sharp.

Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 Convexity theory becomes a hot area of research due to its applications in pure and applied mathematics, especially in optimization theory. The aim of this paper is to introduce a broader class of convex functions by unifying geometrically strong convex function with h convex functions. This new class of functions is called as generalized geometrically

Filterbank optimization with convex objectives and the optimality of principal component forms [PDF]
, 2001 This paper proposes a general framework for the optimization of orthonormal filterbanks (FBs) for given input statistics. This includes as special cases, many previous results on FB optimization for compression. It also solves problems that have not been
