Existence of weak solutions to stochastic evolution inclusions [PDF]

open access: yes, 2004
We consider the Cauchy problem for a semilinear stochastic differential inclusion in a Hilbert space. The linear operator generates a strongly continuous semigroup and the nonlinear term is multivalued and satisfies a condition which is more heneral than

Impulsive evolution inclusions with state-dependent delay and multivalued jumps

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper we prove the existence of a mild solution for a class of impulsive semilinear evolution differential inclusions with state-dependent delay and multivalued jumps in a Banach space.

A cookbook for temporal conceptual data modelling with description logic [PDF]

open access: yes, 2014
We design temporal description logics suitable for reasoning about temporal conceptual data models and investigate their computational complexity. Our formalisms are based on DL-Lite logics with three types of concept inclusions (ranging from atomic ...

Modification of Alumina Inclusions in SWRS82B Steel by Adding Rare Earth Cerium

open access: yesMetals, 2020
The aluminum oxide inclusions in SWRS82B steel seriously affect the drawing performance of the steel strand. In this study, the influence of different additions of cerium (within the range of 0–0.034%) on the composition, morphology, size, number, and ...

Inclusion agglomeration in electrified molten metal: thermodynamic consideration [PDF]

open access: yes, 2016
The effect of electric current on inclusion agglomeration in molten metal has been investigated. It is found that the agglomeration is dependent on the electric current density, distance between inclusions and orientation of electric field.

Optimal Control of History-Dependent Evolution Inclusions with Applications to Frictional Contact

open access: yesJournal of Optimization Theory and Applications, 2020
In this paper, we study a class of subdifferential evolution inclusions involving history-dependent operators. First, we improve an existence and uniqueness theorem and prove the continuous dependence result in the weak topologies. Next, we establish the

Convergence of proximal solutions for evolution inclusions with time-dependent maximal monotone operators [PDF]

open access: yesMathematical programming, 2019
This article studies the solutions of time-dependent differential inclusions which is motivated by their utility in optimization algorithms and the modeling of physical systems.

Evaluation and Analysis of the Influence of Rare-Earth Ce on Inclusions in Heavy Rail Steel

open access: yesMetals, 2023
The effect of rare-earth Ce on the evolution behaviour of inclusions in heavy rail steel was studied. The addition of Ce can significantly reduce the number and size of class A, B, D, and Ds inclusions in the heavy rail steel smelting process.
