, 2009 The definition of a groupoid is presented as well as examples of common structures from which a groupoid can be formed. Haar measure existence and uniqueness theorems for topological groups are used for the construction of Haar systems on groupoids. Some

MathematicsIn this study, we introduce an algorithm that utilizes the Haar wavelet collocation method to solve the time-dependent Emden–Fowler equation. This proposed method effectively addresses both linear and nonlinear partial differential equations.

Frame Set for Gabor Systems with Haar Window
Applied and Computational Harmonic Analysis, 2023 We show the full structure of the frame set for the Gabor system $\mathcal{G}(g;α,β):=\{e^{-2πi mβ\cdot}g(\cdot-nα):m,n\in\Bbb Z\}$ with the window being the Haar function $g=-χ_{[-1/2,0)}+χ_{[0,1/2)}$. The strategy of this paper is to introduce the piecewise linear transformation $\mathcal{M}$ on the unit circle, and to provide a complete ...

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Bionisch inspirierte Strahlungskühlung: Kühlen wie die Silberameise
Physik in unserer Zeit, EarlyView.Wie kann ein wenige Millimeter großes Insekt helfen, Gebäude ohne Strom zu kühlen? Die Silberameise überlebt extreme Hitze mithilfe raffinierter Mikrostrukturen, die einen Großteil des Sonnenlichts zurückwerfen und gleichzeitig thermische Energie über Infrarotstrahlung in den Weltraum abführen.

Harmonic Analysis on Internally Gelfand Pairs Associated to Groupoids
International Journal of Analysis and Applications, 2019 Let G be a topological locally compact, Hausdorff and second countable groupoid with a Haar system and K a proper subgroupoid of G with a Haar system too.

Traffic Density Prediction using IoT-based Double Exponential Smoothing
Knowledge Engineering and Data Science, 2022 The number of vehicles and currents that tend to increase causes traffic density. A system is proposed to calculate the number of vehicles and predict real-time traffic density. This research uses Haar Cascade to detect the number of cars and motorcycles

Cystitis in guinea pigs (Cavia porcellus): Clinical findings and treatment outcomes
Veterinary Record, EarlyView.Abstract Background This retrospective study examined the incidence, diagnostic methods, bacterial isolates, treatments and outcomes associated with cystitis in guinea pigs presented at a single clinic between 2009 and 2022. Methods The clinic's medical records database was reviewed using easyvet software to identify cases eligible for inclusion in the

Uniformly continuous functions on non-Hausdorff groupoids [PDF]
Surveys in Mathematics and its Applications, 2010 The purpose of this paper is to study the notion of uniform continuity introduced in [M. Buneci, Haar systems and homomorphism on groupoids, Operator algebras and mathematical physics, 35-49, Theta, Bucharest, 2003].
