The Gromov-Hausdorff Metric on the Space of Compact Metric Spaces is Strictly Intrinsic [PDF]
, 2015 It is proved that the Gromov-Hausdorff metric on the space of compact metric spaces considered up to an isometry is strictly intrinsic, i.e., the corresponding metric space is geodesic. In other words, each two points of this space (each two compact metric spaces) can be connected by a geodesic.

COMPACTNESS OF THE SPACE OF LEFT ORDERS [PDF]
Journal of Knot Theory and Its Ramifications, 2007 A left order on a magma (e.g. semigroup) is a total order of its elements that is left invariant under the magma operation. A natural topology can be introduced on the set of all left orders of an arbitrary magma. We prove that this topological space is compact.

Digital Methods for the Fatigue Assessment of Engineering Steels
Advanced Engineering Materials, EarlyView.The use of engineering steels is often limited by their fatigue strength. In the sake of a faster product development, the fatigue behavior can be predicted by machine learning (ML). In this work, ML is applied on a heterogeneous database, covering a wide range of steel types.

On a stronger form of hereditary compactness in product spaces [PDF]
arXiv, 1998 The aim of this paper is to continue the study of sg-compact spaces. The class of sg-compact spaces is a proper subclass of the class of hereditarily compact spaces. In our paper we shall consider sg-compactness in product spaces. Our main result says that if a product space is sg-compact, then either all factor spaces are finite, or exactly one factor

Topology and its Applications, 1992 AbstractThe property measure-compact fits between the Lindelöf and realcompact properties, i.e., Lindelöf implies measure-compact implies realcompact. Much of the research on measure-compact spaces centers on two themes: one, what properties measure-compactness shares with Lindelöf and realcompactness and two, the relationships between measure ...

Advanced Engineering Materials, EarlyView.Multilayer ferrite inductor prototypes are fabricated by cofiring metallized tapes of NiCuZn ferrite and glass‐ceramic composite. Prerequisites for a predictive component simulation are discussed. An automated data‐pipeline stores and semantically links the experimental data acquired in the study according to a domain ontology.

Net-Compact Hausdorff Topologies and Continuous Multi-Utility Representations for Closed Preorders
AxiomsIn this paper, we deal with continuous multi-utility representations for closed preorders. We introduce the definition of a net-compact topology, which generalizes the concept of a sequentially compact topology.

Weakly compact composition operators on spaces of Lipschitz functions [PDF]
arXiv, 2014 Let $X$ be a pointed compact metric space. Assuming that $\mathrm{lip}_0(X)$ has the uniform separation property, we prove that every weakly compact composition operator on spaces of Lipschitz functions $\mathrm{Lip}_0(X)$ and $\mathrm{lip}_0(X)$ is compact.

Advanced Engineering Materials, EarlyView.The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.
