A generalization of Laplace and Fourier transforms [PDF]

arXiv, 2017
In this note we propose a generalization of the Laplace and Fourier transforms which we call symmetric Laplace transform. It combines both the advantages of the Fourier and Laplace transforms. We give the definition of this generalization, some examples and basic properties.

Superhydrophobic Solution Blow Spinning PTFE–SiO2 Composite Membranes for Enhanced Liquid–Liquid Extraction

Journal of Applied Polymer Science, EarlyView.
Solution blow spinning PTFE‐SiO2 membrane for membrane assisted solvent extraction. ABSTRACT An ultrafine‐fibrous polytetrafluoroethylene (PTFE)–SiO2 membrane was successfully fabricated using the solution blow spinning (SBS) method. This membrane demonstrated superhydrophobicity (water contact angle > 150°) and oleophilicity (ethyl acetate contact ...

Mass Hierarchies and Quantum Gravity Constraints in DKMM‐refined KKLT

Fortschritte der Physik, Volume 71, Issue 1, January 2023., 2023
Abstract We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an anti D3‐brane in a strongly warped throat. First, we derive the bound resulting from what is usually termed “the throat fitting into the bulk” directly from the Klebanov‐Strassler geometry.

On an application of Laplace transforms

New Trends in Mathematical Science, 2017
In this study, complex differential equations are solved using laplace transform. Firstly we seperate real and imaginer parts of equation. Thus from one unknown equation is obtained two unknown equation system. Later we obtain laplace transforms of real and imaginer parts of solutions using laplace transform.

Bayesian and frequentist statistical models to predict publishing output and article processing charge totals

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Academic libraries, institutions, and publishers are interested in predicting future publishing output to help evaluate publishing agreements. Current predictive models are overly simplistic and provide inaccurate predictions. This paper presents Bayesian and frequentist statistical models to predict future article counts and costs.

Laplace transform of fractional order differential equations

Electronic Journal of Differential Equations, 2015
In this article, we show that Laplace transform can be applied to fractional system. To this end, solutions of linear fractional-order equations are first derived by a direct method, without using Laplace transform.

H∞$$ {H}_{\infty } $$ filtering for 2D continuous‐discrete Takagi–Sugeno fuzzy systems in finite frequency band

Asian Journal of Control, EarlyView.
Abstract This paper focuses on the design of H∞$$ {H}_{\infty } $$ filtering for two‐dimensional (2‐D) continuous‐discrete Takagi–Sugeno (T–S) fuzzy systems. The frequency of disturbance input is assumed to be known and to reside in a finite frequency (FF) domain.

Birth–Death Processes with Two-Type Catastrophes

Mathematics
This paper concentrates on the general birth–death processes with two different types of catastrophes. The Laplace transform of transition probability function for birth–death processes with two-type catastrophes is successfully expressed with the ...

Solution of Differential Equations with Polynomial Coefficients with the Aid of an Analytic Continuation of Laplace Transform

Mathematics, 2016
In a series of papers, we discussed the solution of Laplace’s differential equation (DE) by using fractional calculus, operational calculus in the framework of distribution theory, and Laplace transform.
