Solution to the triharmonic heat equation

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we study the equation $$ frac{partial}{partial t},u(x,t)-c^2circledast u(x,t)=0 $$ with initial condition $u(x,0)=f(x)$. Where x is in the Euclidean space $mathbb{R}^n$, $$ circledast=Big(sum^p_{i=1}frac{partial^2}{partial x^2_i ...

Abstract of: Residual stress distribution in tempered glass with reground edges

open access: yesChallenging Glass Conference Proceedings, 2018
Many glass applications require laminated glass to achieve a safe load-bearing behaviour. Beside the structural aspect, glass elements have to meet high aesthetic demands.

Distribution of Organic-Tempered Pottery in Southeast Europe and the Near East: A Complex Picture. The Case of Northern Greece

open access: yesOpen Archaeology, 2021
Organic-tempered pottery is considered characteristic for the early pottery assemblages in most parts of Southwest Asia and Southeast Europe. The aim of the present paper is to explore: (a) the chronological consistency of this practice, i.e.

Risk measurement using the mixed tempered stable distribution

open access: yes, 2014
The Mixed Tempered Stable distribution (MixedTS) recently introduced has as special cases parametric distributions used in asset return modelling such as the Variance Gamma (VG) and Tempered Stable. In this paper, we start from this flexible distribution

Solutions of a partial differential equation related to the oplus operator

open access: yesElectronic Journal of Differential Equations, 2010
In this article, we consider the equation $$ oplus^ku(x)=sum^{m}_{r=0}c_{r}oplus^{r}delta $$ where $oplus^k$ is the operator iterated k times and defined by $$ oplus^k=Big(Big(sum^p_{i=1}frac{partial^2}{partial x^2_i}Big)^{4}-Big(sum^{p+q}_{j=p+1}

Tempering the Bayes Filter Towards Improved Model-Based Estimation

open access: yesIEEE Open Journal of Control Systems
Model-based filtering is often carried out while subject to an imperfect model, as learning partially-observable stochastic systems remains a challenge.

Effect of Tempering on Structure and Mechanical Properties of Steel 20SiMn3NiA

open access: yesTeshugang, 2010
Structure and mechanical properties of steel 20SiMn3NiA normalized at 860 ℃, oil quenched at 900 ℃ for 40 min and tempered at 180~650℃ for 90~150 min have been studied.

Calibration of the subdiffusive arithmetic Brownian motion with tempered stable waiting-times [PDF]

open access: yes
In the classical analysis many models used to real data description are based on the standard Brownian diffusion-type processes. However, some real data exhibit characteristic periods of constant values.
