Predicting Abrasion Resistance in Thermoplastic Polyurethanes Using Machine Learning

Journal of Applied Polymer Science, EarlyView.
Data‐driven prediction of TPU abrasion resistance using Gradient Boosting Regression (GBR), demonstrating superior performance through an ensemble of decision trees. ABSTRACT Abrasion resistance is a critical property of thermoplastic polyurethane (TPU), especially for applications in automotive, footwear, and medical devices where durability under ...

Growth and Characterization of a CoTPP/NiO(001) Antiferromagnetic Spinterface

Advanced Physics Research, EarlyView.
Co tetraphenyl porphyrins self‐assembled monolayer on NiO form an antiferromagnetic spiterface, in which the paramagnetic molecules inherit a long‐range magnetic ordering from the interaction with the antiferromagnetic oxide. These kind of system combines the versatility of molecules with the potential of antiferromagnets for high‐speed and high ...

New identities for the polarized partitions and partitions with $d$-distant parts

, 2013
In this paper we present a new class of integer partition identities. The number of partitions with d-distant parts can be represented as a sum of the number of partitions with 1-distant parts whose even parts are greater than twice the number of odd ...

Adaptive event‐based asynchronous approach for containment control of Markov jump multi‐agent systems with hidden Markov models

Asian Journal of Control, EarlyView.
Abstract This paper focuses on the issue of adaptive event‐triggered containment control for Markov jump multi‐agent systems characterized by hidden Markov jump parameters. The central objective is to design an output‐feedback controller for the Markov jump multi‐agent system by using an adaptive event‐triggered technique that not only ensures the ...

Microcanonical Entropy, Partitions of a Natural Number into Squares and the Bose–Einstein Gas in a Box

Entropy, 2018
From basic principles, we review some fundamentals of entropy calculations, some of which are implicit in the literature. We mainly deal with microcanonical ensembles to effectively compare the counting of states in continuous and discrete settings. When

Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Delivered cost of switchgrass pellets transported from depots to a biorefinery in the Piedmont, USA

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The southeast region of the USA has the potential to be a significant producer of biobased products; however, research is needed to demonstrate the most cost‐effective feedstock delivery system. This study considers a distributed network of five pellet depots to supply feedstock (i.e., switchgrass pellets) for the operation of a hypothetical ...

The effect of discontinuous injection on particle backflow in pneumatic conveying systems

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Pneumatic conveying is used in many process industries to transport dry, granular, and powdered solids. The triboelectrification of particles during conveying causes particle agglomeration, spark discharges, and disruptions in particle flow, making particles move upstream against the fluid flow. The effect of frequency of particle injection on

Random discrete probability measures based on a negative binomial process

Canadian Journal of Statistics, EarlyView.
Abstract A distinctive functional of the Poisson point process is the negative binomial process for which the increments are not independent but are independent conditional on an underlying gamma variable. Using a new point process representation for the negative binomial process, we generalize the Poisson–Kingman distribution and its corresponding ...

A PAIR OF FOUR-ELEMENT HORIZONTAL GENERATING SETS OF A PARTITION LATTICE

Ural Mathematical Journal
Let \(\lfloor x \rfloor\) and \(\lceil x\rceil \) denote the lower integer part and the upper integer part of a real number \(x\), respectively. Our main goal is to construct four partitions of a finite set \(A\) with \(n\geq 7\) elements such that each ...
