Three-dimensional supergravity reloaded [PDF]

open access: yes, 2006
The locally supersymmetric extension of the most general gravity theory in three dimensions leading to first order field equations for the vielbein and the spin connection is constructed.

Large Depth-of-Field Integral Microscopy by Use of a Liquid Lens

open access: yesSensors, 2018
Integral microscopy is a 3D imaging technique that permits the recording of spatial and angular information of microscopic samples. From this information it is possible to calculate a collection of orthographic views with full parallax and to refocus ...

Three Dimensional Software Modelling [PDF]

open access: yes, 1998
Traditionally, diagrams used in software systems modelling have been two dimensional (2D). This is probably because graphical notations, such as those used in object-oriented and structured systems modelling, draw upon the topological graph metaphor ...

Three-dimensional imaging and scanning: Current and future applications for pathology

open access: yesJournal of Pathology Informatics, 2017
Imaging is vital for the assessment of physiologic and phenotypic details. In the past, biomedical imaging was heavily reliant on analog, low-throughput methods, which would produce two-dimensional images.

Aerodynamic Optimization of Relay Nozzle Using a Chebyshev KAN Surrogate Model Integration and an Improved Multi-Objective Red-Billed Blue Magpie Optimizer

open access: yesBiomimetics
In air jet looms, relay nozzles are critical components in governing airflow velocity and air consumption during the weft insertion process. Although computational fluid dynamics (CFD) offers high-fidelity simulation for aerodynamic analysis, its ...

Three dimensional analysis of natural

open access: yesAlexandria Engineering Journal, 2016
A computational study has been performed to make a computational analysis of natural convection and entropy generation in a sharp edged finned cavity. Three dimensional analysis has been done by solving governing equations with a written computational ...

Three‐dimensional ultrasound [PDF]

open access: yesUltrasound in Obstetrics & Gynecology, 1995
The papers in this issue show that the feasibility of three-dimensional ultrasound methods in the clinical setting using commercially available equipment is nearby. Their results demonstrate some of the advantages compared to two-dimensional ultrasound and other diagnostic modalities, including reduced scanning times that will offer more cost-effective

Three-dimensional hybrid vortex solitons [PDF]

open access: yes, 2014
We show, by means of numerical and analytical methods, that media with a repulsive nonlinearity which grows from the center to the periphery support a remarkable variety of previously unknown complex stationary and dynamical three-dimensional solitary ...

Statistical Timing Analysis for Subthreshold Circuit Based on Bayesian Inference

open access: yesIEEE Access
Accurately predicting the delay distribution of subthreshold circuits is crucial for verifying the timing closure of digital circuits and estimating parameter yields.

Three dimensional conformal sigma models [PDF]

open access: yes, 2007
We construct novel conformal sigma models in three dimensions. Nonlinear sigma models in three dimensions are nonrenormalizable in perturbation theory. We use Wilsonian renormalization group equation method to find the fixed points.
