The role of dual-phase-lag (DPL) heat conduction model on transient free convection flow in a vertical channel

open access: yesPartial Differential Equations in Applied Mathematics, 2022
This work investigates the role of dual-phase-lag (DPL)heat conduction model on transient free convection flow of an incompressible viscous fluid in a vertical channel.

Proposal of an algorithmic methodology in Geo Gebra for the teaching of the Riemann sum a tool for approximating definite integrals

open access: yesJournal of Physics: Conference Series, 2020
Abstract Integral calculus is a fundamental subject that enables the teaching of branches of physics like, mechanics, thermodynamics, and electromagnetism to engineering students. However, the incapacity of understanding either the concept of the area under a curve or to develop an efficient and simple way to calculate integrals ...

Quantum Jackiw-Teitelboim gravity, Selberg trace formula, and random matrix theory

open access: yesPhysical Review Research, 2020
We show that the partition function of quantum Jackiw-Teitelboim (JT) gravity, including topological fluctuations, is equivalent to the partition function of a Maass-Laplace operator of large (imaginary) weight acting on noncompact, infinite-area ...

Comparison of Two Different Analytical Forms of Response for Fractional Oscillation Equation

open access: yesFractal and Fractional, 2021
The impulse response of the fractional oscillation equation was investigated, where the damping term was characterized by means of the Riemann–Liouville fractional derivative with the order α satisfying 0≤α≤2.

On the second moment for primes in an arithmetic progression

open access: yes, 2000
Assuming the Generalized Riemann Hypothesis, we obtain a lower bound within a constant factor of the conjectured asymptotic result for the second moment for primes in an individual arithmetic progression in short intervals. Previous results were averaged

Hybrid scheme for Brownian semistationary processes

open access: yes, 2017
We introduce a simulation scheme for Brownian semistationary processes, which is based on discretizing the stochastic integral representation of the process in the time domain.

Linear Sigma model in the Gaussian wave functional approximation II: Analyticity of the S-matrix and the effective potential/action [PDF]

open access: yes, 2002
We show an explicit connection between the solution to the equations of motion in the Gaussian functional approximation and the minimum of the (Gaussian) effective potential/action of the linear $\Sigma$ model, as well as with the N/D method in ...
