Stochastic Equivalent Linearization for 3‐D Frames

Journal of Engineering Mechanics, 1988
Recent state-of-the-art reports emphasize the generality of stochastic equivalent linearization techniques in the nonlinear dynamic analysis of stochastically excited structures. When a three-dimensional frame is considered, it cannot be studied by decomposing the structure into several plane frames due to the impossibility of summing the effects that ...

A DQN-Based Autonomous Car-Following Framework Using RGB-D Frames

2020 IEEE Global Conference on Artificial Intelligence and Internet of Things (GCAIoT), 2020
Modeling car-following behavior has recently garnered much attention due to the wide variety of applications it may be utilized in, such as accident analysis, driver assessment, and support systems. Some of the latest approaches investigate scenario-based autonomous driving algorithms.

Inelastic Tangential Stiffness for 2‐D Frames

Journal of Structural Engineering, 1983
A general instantaneous or tangential stiffness matrix for a plane frame member is presented. Expressions in the form of integral equations are developed for members having axial forces and arbitrary material properties, distributed loads and moment-axial force-curvature relations.

Deep Learning for Automated Occlusion Edge Detection in RGB-D Frames

Journal of Signal Processing Systems, 2016
Occlusion edges correspond to range discontinuity in a scene from the point of view of the observer. Detection of occlusion edges is an important prerequisite for many machine vision and mobile robotic tasks. Although they can be extracted from range data, extracting them from images and videos would be extremely beneficial.

3-D Frame Vibrations by Consistent Mass Matrix

Journal of the Structural Division, 1973
In the present work, the consistent mass matrix of a component beam of a three-dimensional frame is presented. The frequencies of the example shown are calculated with the consistent mass matrix and compared with the results obtained with the two previous methods.

RELIABILITY EVALUATIONS OF 3-D FRAME SUBJECTED TO NON-STATIONARY EARTHQUAKE

Journal of Sound and Vibration, 2003
The objective of the present work is to evaluate the integrated reliability of multistoried space frame subjected to random earthquake. The stochastic ground motion is described by fully non-stationary sigma-oscillatory model. The stochastic dynamic analysis is performed in the frequency domain to obtain the power spectral density function of random ...

Relative Effectiveness of D-Frame Dip Nets, Quatrefoil Light Traps, and Towed Ichthyoplankton Nets for Larval Muskellunge

North American Journal of Fisheries Management, 2021
Abstract Muskellunge Esox masquinongy are large, predatory game fish whose association with shallow, complex habitats is well documented, particularly during early life stages. Despite this association, relatively little guidance exists regarding effective sampling of Muskellunge larvae and previous efforts to sample larval Muskellunge ...

Fusion of angiography and intravascular ultrasound in vivo: establishing the absolute 3-D frame orientation

IEEE Transactions on Biomedical Engineering, 1999
Data fusion of biplane angiography and intravascular ultrasound (IVUS) facilitates geometrically correct reconstruction of coronary vessels. The locations of IVUS frames along the catheter pullback trajectory can be identified, however the IVUS image orientations remain ambiguous. An automated approach to determination of correct IVUS image orientation

Dynamic Analysis of a 3-D Frame-Membrane Lunar Structure Subjected to Impact

Earth & Space 2008, 2008
A three-dimensional (3-D) frame-membrane structure covered with regolith shielding and pressurized internally has been proposed as a possible lunar habitat. This paper presents results from the dynamic impact analysis of the structure using nonlinear (large deformation) finite element technique.

Coarse to fine global RGB-D frames registration for precise indoor 3D model reconstruction

2017 International Conference on Localization and GNSS (ICL-GNSS), 2017
The conventional approach to register two or more RGB-D frames produced from low cost depth sensors, such as KINECT and Structure Sensor, applies SIFT matched points between color images along with corresponding depth from the depth images. This is known as RGB-D SLAM.
