Application of the Algebraic Extension Method to the Construction of Orthogonal Bases for Partial Digital Convolutions

Algorithms
Mathematical tools have been developed that are analogous to the tool that allows one to reduce the description of linear systems in terms of convolution operations to a description in terms of amplitude-frequency characteristics.

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection

Advanced Intelligent Systems, EarlyView.
We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

Advanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

Elementary Abelianp-extensions of algebraic function fields

Manuscripta Mathematica, 1991
Let \(K\) be a field of characteristic \(p >0\), and let \(F/K\) be an algebraic function field. If \(E/F\) is an elementary abelian Galois extension with Galois group of order \(p^ n\) then \(E\) can be generated over \(F\) by an element \(y\) whose minimal polynomial is of the form \(T^{p^ n}-T-y\).

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.

Positively ramified extensions of algebraic number fields.

Journal für die reine und angewandte Mathematik (Crelles Journal), 1995
This paper is based on the author's thesis of the same title (in German) (1993; Zbl 0803.11059)]. He generalizes results of \textit{K. Wingberg} [J. Reine Angew. Math. 400, 185-202 (1989; Zbl 0715.11065)] on certain Galois groups of CM-fields to fields that are ``locally of CM-type'' at all primes above \(p\).

Bioconvective Unsteady Casson Hybrid Nanofluid Flow on a Variable Darcy Regime Between Two Rotating Disks With Variable Heat Source

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study carries significant consequences in various engineering applications, such as cooling rotating disk surfaces, improving chemical reactor performance, and designing filtration systems. Considering these main applications in view, the aim of this study is to investigate time‐dependent Casson hybrid nanofluid flow on a permeable ...

The epistemic ceiling: Veteran practitioners' perspectives on primary qualification entry standards for teaching secondary mathematics in Scotland

British Educational Research Journal, EarlyView.
Abstract This paper presents an exploratory analysis of contemporary curricular and professional qualification policies in the Scottish education system, focusing on minimum qualification thresholds for mathematics teaching. The study examines how veteran secondary mathematics practitioners perceive the structural and pedagogical implications of using ...

Automated Data‐Efficient Symbolic Regression for Interpretable Bioprocess Model Development

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Bioprocessing is central to the sustainable manufacture of pharmaceuticals, food products, and renewable chemicals. Consequently, developing high‐fidelity kinetic models to facilitate accurate process prediction, optimisation, and scale‐up is a top research priority.
