INVESTIGATION OF THE INFLUENCE OF INFORMATION SECURITY CELL STACK MATERIAL PARAMETERS ON ITS RELIABILITY

open access: yesИзмерение, мониторинг, управление, контроль, 2021
Background. Printed circuit boards of modern analog, digital and digital-analog electronic devices of medium complexity and higher have a base in the form of a stack-a set of layers for various purposes, which are subsequently pressed into a single ...

LaNi0.6Co0.4−xFexO3−δ as Air-Side Contact Material for La0.3Ca0.7Fe0.7Cr0.3O3−δ Reversible Solid Oxide Fuel Cell Electrodes

open access: yesCrystals, 2022
The goal of the current work was to identify an air-side-optimized contact material for La0.3Ca0.7Fe0.7Cr0.3O3−δ (LCFCr) electrodes and a Crofer22APU interconnect for use in reversible solid oxide fuel cells (RSOFCs).

Pancake Flipping is Hard [PDF]

open access: yes, 2011
Pancake Flipping is the problem of sorting a stack of pancakes of different sizes (that is, a permutation), when the only allowed operation is to insert a spatula anywhere in the stack and to flip the pancakes above it (that is, to perform a prefix ...

Monopoles at Finite Volume and Temperature in SU(2) Lattice Gauge Theory

open access: yes, 1996
We resolve a discrepancy between the SU(2) spacial string tension at finite temperature, and the value obtained by monopoles in the maximum Abelian gauge. Previous work had incorrectly omitted a term due to Dirac sheets.

Experimental Investigation of a Solid Oxide Fuel Cell Stack using Direct Reforming Natural Gas [PDF]

open access: yesHydrogen, Fuel Cell & Energy Storage, 2017
In this study, a solid oxide fuel cell (SOFC) stack has been successfully fabricated and tested by using direct natural gas. The main objective of this research was to achieve optimal long-term performance of the SOFC stack without carbon deposition by ...

Emission Characteristics of Polychlorinated Dibenzo-p-Dioxins/Dibenzofurans (PCDD/DFs) in Commercial Bio-SRF and SRF Incineration Plants

open access: yesEnergies, 2022
Incineration plants using solid refused fuel (SRF) should control their air pollution materials to minimize environmental impact. This study evaluated the emission of polychlorinated dibenzo-p-dioxin/dibenzofurans (PCDD/DFs) congener patterns in seven ...

A note on threshold velocity criteria for modelling the solid particle erosion of WC/Co MMCs [PDF]

open access: yes, 2011
The threshold velocity for erosion of a ductile material is considered as the velocity required for initiation of plastic deformation in the substrate.

Mapping stacks of topological stacks [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2010
We prove that the mapping stack Map(Y,X) of topological stacks X and Y is again a topological stack if Y admits a compact groupoid presentation. If Y admits a locally compact groupoid presentation, we show that Map(Y,X) is a paratopological stack. In particular, it has a classifying space (hence, a natural weak homotopy type).

Detect Windows Code Injection by Cross-validating Stack and VAD Information

open access: yesJournal of Harbin University of Science and Technology
Windows 32/64-bit code injection attacks are a common attack technique by malware. In the field of memory forensics, the existing code injection attack detection technologies cannot handle dynamic content in terms of verification integrity, and cannot be
