Semantic Geometric Modelling of Unstructured Indoor Point Cloud

open access: yesISPRS International Journal of Geo-Information, 2018
A method capable of automatically reconstructing 3D building models with semantic information from the unstructured 3D point cloud of indoor scenes is presented in this paper. This method has three main steps: 3D segmentation using a new hybrid algorithm,

Intelligent computational sketching support for conceptual design [PDF]

open access: yes, 2001
Sketches, with their flexibility and suggestiveness, are in many ways ideal for expressing emerging design concepts. This can be seen from the fact that the process of representing early designs by free-hand drawings was used as far back as in the early ...

The Effect of Different Magnetospheric Structures on Predictions of Gamma-ray Pulsar Light Curves

open access: yes, 2014
The second pulsar catalogue of the Fermi Large Area Telescope (LAT) will contain in excess of 100 gamma-ray pulsars. The light curves (LCs) of these pulsars exhibit a variety of shapes, and also different relative phase lags with respect to their radio ...

New chaos-geometric and information technology analysis of chaotic generation regime in a single-mode laser system with absorbing cell

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2015
Here we present the results of application of a new chaos-geometric approach and some information technology algorithms to analysis of chaotic generation regime in a single-mode laser system with absorbing cell. Earlier developed chaos-geometric approach

Prediction of the aerodynamic performance of re-usable single stage to orbit vehicles [PDF]

open access: yes, 2011
Re-usable single stage to orbit launch vehicles promise to reduce the cost of access to space, but their success will be particularly reliant on accurate modelling of their aero-thermodynamic characteristics.

Simulation and hedging oil price with geometric Brownian Motion and single-step binomial price model [PDF]

open access: yes, 2017
This paper[1] uses the Geometric Brownian Motion (GBM) to model the behaviour of crude oil price in a Monte Carlo simulation framework. The performance of the GBM method is compared with the naïve strategy using different forecast evaluation techniques ...
