Topology optimization with geometrical constraints based on fictitious physical models (The geometrical constraint for molding and milling)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
This paper proposes a scheme for imposing geometrical constraints in topology optimization for molding and milling so that optimal configurations that guarantee manufacturability can be obtained, based on the fictitious physical model. First, a level set-

Factor Price Equalization : Geometrical Conditions [PDF]

open access: yes, 1998
This paper presents a geometrical approach to the univalence problem for a system of cost functions. We present a natural (almost tautological) extension of a geometrical theorem due to McKenzie: our sufficient condition is related to the non ...

Optimization of geometrical parameter for V-type alpha Stirling engine based on dimensionless analysis [PDF]

open access: yesMATEC Web of Conferences, 2018
This paper aims to study the effect of mechanism and geometrical parameters on the shaft work of alpha-type Stirling engine with V-cylinder arrangement and find the appropriate value of geometrical parameters to get the maximum value of shaft work output.

On the geometrical interpretation of scale-invariant models of inflation

open access: yesPhysics Letters B, 2016
We study the geometrical properties of scale-invariant two-field models of inflation. In particular, we show that when the field-derivative space in the Einstein frame is maximally symmetric during inflation, the inflationary predictions can be universal

Modeling Realistic Geometries in Human Intrathoracic Airways

open access: yesDiagnostics
Geometrical models of the airways offer a comprehensive perspective on the complex interplay between lung structure and function. Originating from mathematical frameworks, these models have evolved to include detailed lung imagery, a crucial enhancement ...

Detecting dynamical patterns in pedestrian bottlenecks Koopman-based quantification of crowd dynamics [PDF]

open access: yesEPJ Web of Conferences
What properties characterize a bottleneck through which pedestrians are walking? Using Koopman theory, we analyze simulated bottleneck scenarios for their underlying geometrical components.

The Geometric Block Model

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2018
To capture the inherent geometric features of many community detection problems, we propose to use a new random graph model of communities that we call a Geometric Block Model. The geometric block model generalizes the random geometric graphs in the same way that the well-studied stochastic block model generalizes the Erdös-Renyi random

POPULATING A LIBRARY OF REUSABLE H-BOMS: ASSESSMENT OF A FEASIBLE IMAGE BASED MODELING WORKFLOW [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
The paper shows the intermediate results of a research activity aimed at populating a library of reusable Historical Building Object Models (H-BOMs) by testing a full digital workflow that takes advantages from using Structure from Motion (SfM) models ...

Information Geometrical Characterization of Quantum Statistical Models in Quantum Estimation Theory

open access: yesEntropy, 2019
In this paper, we classify quantum statistical models based on their information geometric properties and the estimation error bound, known as the Holevo bound, into four different classes: classical, quasi-classical, D-invariant, and asymptotically ...
