Theorems on n-dimensional Laplace transforms and their applications
Electronic Journal of Differential Equations, 1999 In the present paper we prove certain theorems involving the classical Laplace transform of $n$-variables. The theorems are then shown to yield a nice algorithm for evaluating $n$-dimensional Laplace transform pairs.

On exit time of stable processes [PDF]
arXiv, 2011 We study the exit time $\tau=\tau_{(0,\infty)}$ for 1-dimensional strictly stable processes and express its Laplace transform at $t^\alpha$ as the Laplace transform of a positive random variable with explicit density. Consequently, $\tau$ satisfies some multiplicative convolution relations. For some stable processes, e.g.

Dynamic Properties of the Warm Dense Uniform Electron Gas With the qSTLS Dielectric Scheme
Contributions to Plasma Physics, EarlyView.ABSTRACT The recently derived Fourier–Matsubara expansion of imaginary–time correlation functions comprises an exact result of linear response theory for finite‐temperature quantum many‐body systems. In its density–density version, the expansion facilitates systematic comparisons between quasi‐exact ab initio path integral Monte Carlo simulations and ...

Creep properties and constitutive model of diabase in deep water conveyance tunnels
Deep Underground Science and Engineering, EarlyView.The axial and lateral creep characteristics of diabase were analyzed based on compression creep tests. The nonlinear viscoelastic‐plastic model capable of describing the whole creep process was established based on the fractional derivative and damage theories.

Real‐time simulation multi‐point decoupling method of power systems based on terminal resistor
IET Generation, Transmission &Distribution, Volume 16, Issue 24, Page 4914-4923, December 2022., 2022 Abstract Traditional decoupling methods in real‐time simulation of complex power systems are poor in stability and unsatisfactory in use. In order to solve this problem, an improved decoupling method based on a terminal resistor is proposed. By paralleling a fixed‐value resistor and inverse‐paralleling a controlled current source in the traditional ...

ELECTROPHORESIS, EarlyView.ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Intent Arabic text categorisation based on different machine learning and term frequency
IET Networks, EarlyView., 2022 Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...
