New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design

open access: yesAdvanced Engineering Materials, EarlyView.
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Slant spacelike ruled surfaces and their Bertrand offsets

open access: yesFrontiers in Physics
In this work, we investigate the synthesis problem of slant spacelike ruled surfaces and associated Bertrand offsets (BO) in E13 (Minkowsk 3-space). We provide the parametric equation for a non-developable spacelike ruled surface (SLRS) by using the ...

Intersection theory over quantum ruled surfaces [PDF]

open access: yes, 2007
In this paper, we will extend several results on intersection theory over commutative ruled surfaces to quantum ruled surfaces. Typically, we define the fiber of a closed point, the quasi-section, and the quasi-canonical divisor on a quantum rules ...

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

open access: yesAdvanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Theories and Methods for Development of Developable Ruled Surfaces and Approximate Flattening of Non-developable Surfaces

open access: yesDiségno, 2018
Geometric genesis of surfaces and knowledge of their properties are basis for solving many problems, both constructive and measurement. A developable surface can be manufactured starting from a flat “strip”, using a flexible and non-deformable material.

On projections of ruled and veronese surfaces

open access: yesJournal of Algebra, 1989
A closed subscheme \(X\subset {\mathbb{P}}^ n\) is said to be of maximal rank if for every \(h\geq 1\) the restriction homomorphism \(H^ 0({\mathcal O}_{{\mathbb{P}}^ n}(h))\to H^ 0({\mathcal O}_ X(h))\) is injective or surjective. In many previous papers the authors gave contributions to answer the following question (Hartshorne projection conjecture).

OntOMat: Toward Ontology‐Based Product and Process Design Engineering and Optimization Solutions Fueling Circular Value Chains

open access: yesAdvanced Engineering Materials, EarlyView.
The OntOMat ontology establishes a structured framework for polymer matrix fiber reinforced composite materials, integrating manufacturing processes, characterization methods, and multiscale design through the VDI/VDE 3682 formalized process description standard.

Some foliations on ruled surfaces

open access: yes, 1994
In this paper, (complex analytic) foliations on ruled surfaces leaving a curve invariant and having no singularities on it are observed. Classification of ruled surfaces and curves with such foliations is done and examples of each case are ...
