Weak Subdifferential in Nonsmooth Analysis and Optimization [PDF]

open access: yesJournal of Applied Mathematics, 2011
Some properties of the weak subdifferential are considered in this paper. By using the definition and properties of the weak subdifferential which are described in the papers (Azimov and Gasimov, 1999; Kasimbeyli and Mammadov, 2009; Kasimbeyli and ...

Smoothed quantile residual life regression analysis with application to the Korea HIV/AIDS cohort study [PDF]

open access: yesBMC Medical Research Methodology
Background The residual life of a patient with human immunodeficiency virus (HIV) is of major interest to patients and their physicians. While existing analyses of HIV patient survival focus mostly on data collected at baseline, residual life analysis ...

Bolza type problems in infinite dimensional discrete time [PDF]

open access: yesJournal of Hyperstructures, 2013
In this paper we study a discrete time version of deterministic models in optimization in infinite dimensional. The functionals are assumed to be merely lower semi continuous.

Semidefinite Multiobjective Mathematical Programming Problems with Vanishing Constraints Using Convexificators

open access: yesFractal and Fractional, 2021
In this paper, we establish Fritz John stationary conditions for nonsmooth, nonlinear, semidefinite, multiobjective programs with vanishing constraints in terms of convexificator and introduce generalized Cottle type and generalized Guignard type ...

Stability and Periodic Motions for a System Coupled with an Encapsulated Nonsmooth Dynamic Vibration Absorber

open access: yesApplied Sciences, 2023
The dynamic vibration absorber (DVA) is widely used in engineering models with complex vibration modes. The research on the stability and periodic motions of the DVA model plays an important role in revealing its complex vibration modes and energy ...

Asymptotic stationarity and regularity for nonsmooth optimization problems [PDF]

open access: yesJournal of Nonsmooth Analysis and Optimization, 2020
Based on the tools of limiting variational analysis, we derive a sequential necessary optimality condition for nonsmooth mathematical programs which holds without any additional assumptions. In order to ensure that stationary points in this new sense are

Duality for nonsmooth mathematical programming problems with equilibrium constraints

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we consider the mathematical programs with equilibrium constraints (MPECs) in Banach space. The objective function and functions in the constraint part are assumed to be lower semicontinuous.

Investigation of the Effect of Dimple Bionic Nonsmooth Surface on Tire Antihydroplaning

open access: yesApplied Bionics and Biomechanics, 2015
Inspired by the idea that bionic nonsmooth surfaces (BNSS) reduce fluid adhesion and resistance, the effect of dimple bionic nonsmooth structure arranged in tire circumferential grooves surface on antihydroplaning performance was investigated by using ...

The calculation of discriminating kernel based on viability kernel and reachability

open access: yesAdvances in Difference Equations, 2017
We discuss the calculation of discriminating kernel for the discrete-time dynamic game and continuous-time dynamic game (namely differential game) using the viability kernel and reachable set.
