Lattice-valued continuous convergence is induced by a lattice-valued uniform convergence structure

open access: yes, 2006
We define a stratified L-uniform convergence structure on the set of all continuous mappings from a stratified L-limit space to a stratified L-uniform convergence space. This structure induces L-continuous convergence. This shows that the category of all

Theoretical and experimental evaluations of the convective and conductive heat transfers in a domestic hot-water store [PDF]

open access: yes, 1991
The design of a water based thermal store for use in a domestic central heating system has been investigated theoretically, experimentally and numerically.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

High-Frequency Green’s Function for a Semi-Infinite Array of Electric Dipoles on an Infinite Grounded Stratified Dielectric Slab. Part II: Spatial Domain Parameterization

open access: yes, 2005
This second part of a three-paper sequence deals with the spatial domain parametrization and physical interpretation of the relevant asymptotic high-frequency Green's function for a semi-infinite phased array of parallel dipoles on an infinite stratified

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Stratified deformation space and path planning for a planar closed chain with revolute joints

open access: yes, 2008
Given a linkage belonging to any of several broad classes (both planar and spatial), we have defined parameters adapted to a stratification of its deformation space (the quotient space of its configuration space by the group of rigid motions) making that

Microstructure measurements and estimates of entrainment in the Denmark Strait overflow plume [PDF]

open access: yes, 2013
To examine processes controlling the entrainment of ambient water into the Denmark Strait overflow (DSO) plume/gravity current, measurements of turbulent dissipation rate were carried out by a quasi-free-falling (tethered) microstructure profiler (MSP ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

On the category of $L$-fuzzy neighborhood groups and its connections with various categories of $L$-convergence groups

open access: yes, 2010
Motivated by the notion of $L$-fuzzy neighborhood system attributed to U. Hohle and A. P. Sostak [Axiomatic foundations of fixed basis fuzzy topology, in: Mathematics of Fuzzy Sets: Topology, Logic and Measure Theory, Edited by U. Hohle and S.
