Bessel Beam Dielectrics Cutting with Femtosecond Laser in GHz-Burst Mode

open access: yesMicromachines, 2023
We report, for the first time to the best of our knowledge, Bessel beam dielectrics cutting with a femtosecond laser in GHz-burst mode. The non-diffractive beam shaping is based on the use of an axicon and allows for cutting glasses up to 1 mm thickness ...

Bayesian Inference of a Non normal Multivariate Partial Linear Regression Model [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2021
This research includes the Bayesian estimation of the parameters of the multivariate partial linear regression model when the random error follows the matrix-variate generalized modified Bessel distribution and found the statistical test of the model ...

Sharp Estimates of Transition Probability Density for Bessel Process in Half-Line [PDF]

open access: yes, 2013
In this paper we study the Bessel process Rt(μ)$R_{t}^{(\mu )}$ with index μ ≠ 0 starting from x > 0 and killed when it reaches a positive level a, where x > a > 0. We provide sharp estimates of the transition probability density pa(μ)(t,x,y)$p_{a}^{(\mu

Gap Probabilities for the Generalized Bessel Process: A Riemann-Hilbert Approach [PDF]

open access: yes, 2013
We consider the gap probability for the Generalized Bessel process in the single-time and multi-time case, a determinantal process which arises as critical limiting kernel in the study of self-avoiding squared Bessel paths.

Some explicit formulas for the Brownian bridge, Brownian meander and Bessel process under uniform sampling [PDF]

open access: yes, 2013
We show that simple explicit formulas can be obtained for several relevant quantities related to the laws of the uniformly sampled Brownian bridge, Brownian meander and three dimensional Bessel process. To prove such results, we use the distribution of a

Bessel Beam Generation Using Dielectric Planar Lenses at Millimeter Frequencies

open access: yesIEEE Access, 2020
In this work a dielectric planar lens is proposed to generate a Bessel beam. The lens works at Ka-band and produces a non-diffraction range within the Fresnel region of the antenna.

Application of the Generalized Bessel Function to Two-Color Phase-of-the-Phase Spectroscopy

open access: yesMathematics, 2022
In two-color strong field ionization of atoms, dynamical characteristics such as ionization rate and electron trajectory depend heavily on the relative phase of the strong fundamental field and its second harmonic.

REGARDING SOME FUNDAMENTAL ASPECTS OF DESIGN AND DEVELOPMENT OF BESSEL ULTRASONIC CONCENTRATORS USED IN NONCONVENTIONAL MACHINING

open access: yesNonconventional Technologies Review, 2023
In the category of nonconventional machining, the use of concentrated energy from ultrasonic mechanical oscillations has long been a practical solution for efficient technological utilization. This work comprehensively develops and addresses an algorithm
