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 ...
