Existence and Stability of Solutions for Implicit Multivalued Vector Equilibrium Problems

open access: yesFixed Point Theory and Applications, 2011
A class of implicit multivalued vector equilibrium problems is studied. By using the generalized Fan-Browder fixed point theorem, some existence results of solutions for the implicit multivalued vector equilibrium problems are obtained under some ...

Variational problems with inequality constraints

open access: yesJournal of Mathematical Analysis and Applications, 1962
In an earlier paper [I] we showed how the local characterization of optimality of dynamic programming led to simple derivations of many of the results of the calculus of variations. Except for one brief section, we restricted our attention to the Problem of Lagrange.

On the Generalized Quasi-variational Inequality Problems

open access: yesJournal of Mathematical Analysis and Applications, 1996
The authors have obtained many existence results for generalized quasi-variational inequalities problems by using the fixed point techniques. The results obtained in this paper contain the previously known results as special cases.

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

open access: yesAsian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

A Class of Quasistatic Contact Problems for Viscoelastic Materials with Nonlocal Coulomb Friction and Time-Delay

open access: yesMathematical Modelling and Analysis, 2014
In this paper, a mathematical model which describes the explicit time dependent quasistatic frictional contact problems is introduced and studied. The material behavior is described with a nonlinear viscoelastic constitutive law with time-delay and the ...

Advanced therapy medicinal products (ATMPs) – An analysis of the global regulatory status

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Background A rapid progress in the development of advanced therapy medicinal products (ATMPs) has taken place over the past decades. The ATMPs hold great potential but face challenges in the clinical development and the regulatory process.

THE TIKHONOV REGULARISATION METHOD FOR PSEUDOMONOTONE EQUILIBRIUM PROBLEMS

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2012
We extend the Tikhonov regularisation method widely used in optimisation and variational inequalities to pseudomonotone equilibrium problems. In this case, the Tikhonov regularised sub-problems have a unique solution only in the limit, but any Tikhonov ...

Activism as education in and through the youth climate justice movement

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Young people worldwide are increasingly participating in a global movement for climate justice, yet to date, little research has examined how youth climate justice activists conceive of and experience activism as education. The present study used in‐depth, semi‐structured interviews with 16 US climate justice activists (aged 15–17) to address ...

A class of uncertain variational inequality problems

open access: yes, 2015
In this paper, we propose a new class of variational inequality problems, say, uncertain variational inequality problems based on uncertainty theory in finite Euclidean spaces Rn$R^{n}$.
