Algorithm-Aided Design for Composite Bridges

open access: yesBuildings, 2023
Bridges are geometrically complex infrastructures, and their designs usually exhibit significant geometric variations between different structural solutions.

On mathematical modelling of insect flight dynamics in the context of micro air vehicles [PDF]

open access: yes, 2006
This paper discusses several aspects of mathematical modelling relevant to the flight dynamics of insect flight in the context of insect-like flapping wing micro air vehicles (MAVs).

The Oblate Schwarzschild Approximation for Light Curves of Rapidly Rotating Neutron Stars [PDF]

open access: yes, 2007
We present a simple method for including the oblateness of a rapidly rotating neutron star when fitting X-ray light curves. In previous work we showed that the oblateness induced by rotation at frequencies above 300 Hz produces a geometric effect which ...

Geometric Characterisation of Stochastic Fibrous Networks: A Comprehensive Review

open access: yesFibers
Fibrous networks are porous materials that can have stochastic and uniform microstructures. Various fibrous networks can be found in nature (e.g., collagens, hydrogels, etc.) or manufactured (e.g., composites and nonwovens).

The effects of age, sex and season on the macronutrient composition of the diet of the domestic Asian elephant

open access: yesJournal of Applied Animal Research, 2019
Limited data are available on the relationship between seasonal diets and macronutrient and energy intake of domestic Asian elephants. The effects of age, sex and season on the nutrient composition and intake of food were investigated using 16 ...

Determining geometric primitives for a 3D GIS : easy as 1D, 2D, 3D? [PDF]

open access: yes, 2015
Acquisition techniques such as photo modelling, using SfM-MVS algorithms, are being applied increasingly in several fields of research and render highly realistic and accurate 3D models.

RESEARCH AND IMPLEMENTATION OF 3D CITY BATCH RAPID MODELLING METHOD [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
For the current 3D city modelling, the use of computer programs for batch modelling of non-fine models can only ensure the building height information, and cannot effectively use the attribute information of 2D data; and the manual modelling method for ...

Geometric continuous patch complexes [PDF]

open access: yes, 1987
A theory of geometric continuity of arbitrary order is presented. Conditions of geometric continuity at a vertex where a number of patches meet are investigated.

Almost Kaehler Ricci Flows and Einstein and Lagrange-Finsler Structures on Lie Algebroids

open access: yes, 2013
In this work we investigate Ricci flows of almost Kaehler structures on Lie algebroids when the fundamental geometric objects are completely determined by (semi) Riemannian metrics, or effective) regular generating Lagrange/ Finsler, functions. There are

Tolerance Synthesis of Delta-like Parallel Robots Using a Nonlinear Optimisation Method

open access: yesApplied Sciences, 2023
Robotic systems require high accuracy in manipulating objects. Positioning errors are influenced by geometric tolerances and various sources. This paper introduces a new technique based on the interior-point algorithm optimisation method to allocate ...
