Stratifying Quotient Stacks and Moduli Stacks [PDF]

open access: yes, 2018
Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S/H] has a geometric quotient S/H ...

Stack-sorting with consecutive-pattern-avoiding stacks [PDF]

open access: yesAdvances in Applied Mathematics, 2021
We introduce consecutive-pattern-avoiding stack-sorting maps $\text{SC}_σ$, which are natural generalizations of West's stack-sorting map $s$ and natural analogues of the classical-pattern-avoiding stack-sorting maps $s_σ$ recently introduced by Cerbai, Claesson, and Ferrari.

Sorting and preimages of pattern classes [PDF]

open access: yes, 2012
We introduce an algorithm to determine when a sorting operation, such as stack-sort or bubble-sort, outputs a given pattern. The algorithm provides a new proof of the description of West-2-stack-sortable permutations, that is permutations that are ...

Wear maps for TiC composite based coatings deposited on 303 stainless steel [PDF]

open access: yes, 2014
Dry sliding wear (pin-on-disc) tests were carried out under ambient conditions at room temperature for TiC coated and uncoated 303 stainless steel, using alumina as a counterface.

Effect of Cell Size on the Performance and Temperature Distribution of Molten Carbonate Fuel Cells

open access: yesEnergies, 2020
Molten carbonate fuel cells (MCFCs) are high-operating-temperature fuel cells with high efficiency and fuel diversity. Electrochemical reactions in MCFCs are exothermic.

Agentic AI in Cloud-Based Credit Card Fraud Detection: Towards Autonomous Risk Mitigation

open access: yesITEGAM-JETIA
Credit card fraud (CCF) still remains an ongoing concern for financial institutions because to the huge disparity between genuine and fraudulent transactions, as well as the ever-changing behavior of fraudsters. This paper proposes a cloud-based Agentic
