A note on contributions concerning nonseparable spaces with respect to signal processing within Bayesian frameworks

open access: yesMathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1178-1184, 15 January 2023., 2023
In this paper, we discuss the study of some signal processing problems within Bayesian frameworks and semigroups theory, in the case where the Banach space under consideration may be nonseparable. For applications, the suggested approach may be of interest in situations where approximation in the norm of the space is not possible.

Tellurium‐Free, Sustainable Thermoelectric Device for Mid‐Temperature Waste Heat Recovery

open access: yesCarbon Energy, EarlyView.
We demonstrate the novel, low‐cost, non‐toxic, earth‐abundant p‐type and n‐type combination of materials for TEG fabrication. Sustainably fabricated TEG demonstrated a remarkable power of 5 mW and a maximum conversion efficiency of 4.6%. ABSTRACT Famatinite (Cu3SbS4, p‐type) and chalcopyrite (CuFeS2, n‐type) are well‐recognized sustainable minerals ...

TiNiSi‐Type ALiAu (A = Ca, Sr, Ba, Eu, Yb) Compounds: Alternative Use of “Excess” Electrons

open access: yesChemistry – A European Journal, EarlyView.
Excess electrons distinguish the bonding in ALiAu (A = Yb, Ca, Eu, Sr, Ba), a new series of intermetallic compounds crystallizing in TiNiSi type. According to bonding analysis, these metallic phases are classified as aurides containing polycations with multiatomic bonding between A, Li, and Au . Abstract New TiNiSi‐type compounds ALiAu (A = Ca, Sr, Ba,

Efficient space‐time adaptivity for parabolic evolution equations using wavelets in time and finite elements in space

open access: yesNumerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023
Abstract Considering the space‐time adaptive method for parabolic evolution equations we introduced in Stevenson et al., this work discusses an implementation of the method in which every step is of linear complexity. Exploiting the tensor‐product structure of the space‐time cylinder, the method allows for a family of trial spaces given as spans of ...
