Transverse Cracking in a Fiber Reinforced Ceramic Matrix Composite [PDF]

open access: yes, 1990
The purpose of this study was to investigate the transverse cracking behavior of a fiber reinforced ceramic matrix composite. The major objectives were to determine the crack initiation stress and the minimum transverse crack spacing for different cross ...

Beiträge zur Robusten Optimierung: Netzwerkflüsse, Marktgleichgewichte, Lineare Komplementaritätsprobleme und Pareto-Optimalität [PDF]

open access: yes, 2023
In applications, often not all parameters of optimization problems are known precisely, for example, due to measurement inaccuracies or imprecise statistical predictions. Optimization under uncertainty, therefore, plays an increasingly important role in

Uncertain Chinese Postman Problem with Budget Constraint: A Robust Optimization Approach

open access: yes, 2023
The Chinese postman problem (CPP) is a well-known combinatorial optimization problem, that is used in various real-world applications. Modeling such real-world applications frequently necessitates taking into account some uncertain variables.

Non-Smooth, H\"older-Smooth, and Robust Submodular Maximization

open access: yes, 2023
We study the problem of maximizing a continuous DR-submodular function that is not necessarily smooth. We prove that the continuous greedy algorithm achieves an $[(1-1/e)\OPT-\epsilon]$ guarantee when the function is monotone and H\"older-smooth, meaning

Expedient method for oxidation of alcohol by hydrogen peroxide in the presence of amberlite IRA 400 resin (basic) as phase-transfer catalyst [PDF]

open access: yes, 2008
Amberlite IRA 400 (strongly basic), a classical polymer imparts phasetransfer catalysis in the oxidation of primary and secondary alcohols by hydrogen peroxide to give excellent yields of the corresponding carbonyl compounds or carboxylic acids in ...

A Moment-SOS Hierarchy for Robust Polynomial Matrix Inequality Optimization with SOS-Convexity

open access: yes, 2023
We study a class of polynomial optimization problems with a robust polynomial matrix inequality (PMI) constraint where the uncertainty set itself is defined also by a PMI. These can be viewed as matrix generalizations of semi-infinite polynomial programs,

On modelling planning under uncertainty in manufacturing [PDF]

open access: yes, 2007
We present a modelling framework for two-stage and multi-stage mixed 0−1 problems under uncertainty for strategic Supply Chain Management, tactical production planning and operations assignment and scheduling.

Optimal Learning via Moderate Deviations Theory

open access: yes, 2023
This paper proposes a statistically optimal approach for learning a function value using a confidence interval in a wide range of models, including general non-parametric estimation of an expected loss described as a stochastic programming problem or ...

Implicit regularization in AI meets generalized hardness of approximation in optimization -- Sharp results for diagonal linear networks

open access: yes, 2023
Understanding the implicit regularization imposed by neural network architectures and gradient based optimization methods is a key challenge in deep learning and AI.
