Decomposability and convex structure of thermal processes [PDF]

New Journal of Physics, 2018
We present an example of a Thermal Process for a system of $d$ energy levels, which cannot be performed without an instant access to the whole energy space. This Thermal Process is uniquely connected with a transition between some states of the system, that cannot be performed without access to the whole energy space even when approximate transitions ...

Tricorns and Multicorns in Noor Orbit With s-Convexity

IEEE Access, 2019
In today’s world, complex patterns of the dynamical framework have astounding highlights of fractals and become a huge field of research because of their beauty and unpredictability of their structure.

Additive Structure in Convex Sets

Combinatorica
Abstract This paper considers some different measures for how additively structured a convex set can be. The main result gives a construction of a convex set A containing $$\Omega (|A|^{3/2})$$

Existence of Equilibria for Discontinuous Games in General Topological Spaces with Binary Relations

Journal of Function Spaces, 2018
We provide several results on the existence of equilibria for discontinuous games in general topological spaces without any convexity structure. All of the theorems yielding existence of equilibria here are stated in terms of the player’s preference ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Further Properties of 1- and 2-Dimensional U- and W-Convexity and Fixed Point of Nonexpansive Mappings in Banach Spaces X and X∗

Journal of Mathematics, 2021
In this paper, we further studied properties of the modulus of n-dimensional U-convexity and the modulus of n-dimensional U-flatness when n = 1 (2-dimensional character) and n = 2 (3-dimensional character).

Convex Learning of Multiple Tasks and their Structure

CoRR, 2015
Reducing the amount of human supervision is a key problem in machine learning and a natural approach is that of exploiting the relations (structure) among different tasks. This is the idea at the core of multi-task learning. In this context a fundamental question is how to incorporate the tasks structure in the learning problem.We tackle this question ...
