A Hybrid 3D Indoor Space Model [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
GIS integrates spatial information and spatial analysis. An important example of such integration is for emergency response which requires route planning inside and outside of a building. Route planning requires detailed information related to indoor and

Hypergraph modelling for geometric model fitting [PDF]

Pattern Recognition, 2016
In this paper, we propose a novel hypergraph based method (called HF) to fit and segment multi-structural data. The proposed HF formulates the geometric model fitting problem as a hypergraph partition problem based on a novel hypergraph model. In the hypergraph model, vertices represent data points and hyperedges denote model hypotheses. The hypergraph,

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

MATEC 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.

Geometric models of Helium [PDF]

Modern Physics Letters A, 2017
A previous paper [M. F. Atiyah and N. S. Manton, arXiv:1609.02816 ] modeled atoms and their isotopes by complex algebraic surfaces with the projective plane modeling Hydrogen. In this paper, models of the stable isotopes Helium-4 and Helium-3 are constructed.

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

Nihon 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-

On the geometrical interpretation of scale-invariant models of inflation

Physics 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

The Geometric Block Model

Proceedings 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

Modeling Realistic Geometries in Human Intrathoracic Airways

Diagnostics
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]

EPJ 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.

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

The 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 ...
