Notes on Lipschitz Properties of Nonlinear Scalarization Functions with Applications

open access: yesAbstract and Applied Analysis, 2014
Various kinds of nonlinear scalarization functions play important roles in vector optimization. Among them, the one commonly known as the Gerstewitz function is good at scalarizing.

Viability and Feasibility of Constrained Kinematic Control of Manipulators

open access: yesRobotics, 2018
Recent advances in planning and control of robot manipulators make an increasing use of optimization-based techniques, such as model predictive control. In this framework, ensuring the feasibility of the online optimal control problem is a key issue.

Dynamic Network Design Problem under Demand Uncertainty: An Adjustable Robust Optimization Approach

open access: yesDiscrete Dynamics in Nature and Society, 2014
This paper develops an adjustable robust optimization approach for a network design problem explicitly incorporating traffic dynamics and demand uncertainty. In particular, a cell transmission model based network design problem of linear programming type

A polyhedral approach to the multi-layer crossing minimization problem [PDF]

open access: yes, 1997
We study the multi-layer crossing minimization problem from a polyhedral point of view. After the introduction of an integer programming formulation of the multi-layer crossing minimization problem, we examine the 2-layer case and derive several classes of facets of the associated polytope. Preliminary computational results for 2- and 3-layer instances

Mesh morphing-based pre-processing and numerical simulation of blockage accident in lead–bismuth fast reactor fuel assembly

open access: yesNuclear Engineering and Technology
This paper presents a CFD modeling approach for a 19-rod bundle fuel assembly with spiral semi-cylindrical ribs, which potentially can be used for liquid metal cooled fast reactor, as well as a numerical simulation of flow and thermal behavior under ...

Set-theoretic detection of data corruption attacks on cyber physical power systems

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
This paper addresses a set-theoretic method for the detection of data corruption cyber-attacks on the load frequency control loop of a networked power system. The system consists of several interconnected control areas forming a power grid.

Tiling arbitrarily nested loops by means of the transitive

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2016
A novel approach to generation of tiled code for arbitrarily nested loops is presented. It is derived via a combination of the polyhedral and iteration space slicing frameworks. Instead of program transformations represented by a set of affine functions,
