Interface reduction for Hurty/Craig-Bampton substructured models: Review and improvements
(2019)The Hurty/Craig-Bampton method in structural dynamics represents the interior dynamics of each subcomponent in a substructured system with a truncated set of normal modes and retains all of the physical degrees of freedom ... -
Nonlinear modeling of structures with bolted joints: A comparison of two approaches based on a time-domain and frequency-domain solver
(2019)Motivated by the current demands in high-performance structural analysis, and by a need to better model systems with localized nonlinearities, analysts have developed a number of different approaches for modeling and ... -
A Review of Intent Detection, Arbitration, and Communication Aspects of Shared Control for Physical Human–Robot Interaction
(2018)As robotic devices are applied to problems beyond traditional manufacturing and industrial settings, we find that interaction between robots and humans, especially physical interaction, has become a fast developing field. ... -
Compressible-flow geometric-porosity modeling and spacecraft parachute computation with isogeometric discretization
(2018)One of the challenges in computational fluid–structure interaction (FSI) analysis of spacecraft parachutes is the “geometric porosity,” a design feature created by the hundreds of gaps and slits that the flow goes through. ... -
The effect of plate design, bridging span, and fracture healing on the performance of high tibial osteotomy plates: An experimental and finite element study
(2018)Objectives: Opening wedge high tibial osteotomy (HTO) is an established surgical procedure for the treatment of early-stage knee arthritis. Other than infection, the majority of complications are related to mechanical ... -
A finite element model for magnetohydrodynamic squeeze-film flows
(2018)A computational model is developed to analyze magnetohydrodynamic (MHD) squeeze-film flows featuring an electrically conducting fluid subjected to imposed magnetic and electric fields. The model is based on the so-called ... -
Quantitative Testing of fMRI-Compatibility of an Electrically Active Mechatronic Device for Robot-Assisted Sensorimotor Protocols
(2018)OBJECTIVE: To develop a quantitative set of methods for testing the functional magnetic resonance imaging (fMRI) compatibility of an electrically-active mechatronic device developed to support sensorimotor protocols during ... -
Strain Hardening for Elastic-Perfectly Plastic to Perfectly Elastic Flattening Single Asperity Contact
(2018)For elastic contact, an exact analytical solution for the stresses and strains within two contacting bodies has been known since the 1880s. Despite this, there is no similar solution for elastic-plastic contact due to the ... -
Assessing Wrist Movement With Robotic Devices
(2018)Robotic devices have been proposed to meet the rising need for high intensity, long duration, and goal-oriented therapy required to regain motor function after neurological injury. Complementing this application, exoskeletons ... -
Conveying language through haptics: a multi-sensory approach
(2018)In our daily lives, we rely heavily on our visual and auditory channels to receive information from others. In the case of impairment, or when large amounts of information are already transmitted visually or aurally, ... -
Trajectory Deformations From Physical Human–Robot Interaction
(2018)Robots are finding new applications where physical interaction with a human is necessary, such as manufacturing, healthcare, and social tasks. Accordingly, the field of physical human-robot interaction (pHRI) has leveraged ... -
Reflection on System Dynamics Principles Improves Student Performance in Haptic Paddle Labs
(2018)Contribution: Significant effort has been placed on the development of laboratory exercises for mechanical engineering curricula. Often, however, the exercises are not structured to encourage students to see the labs as a ... -
Electromagnetic tracking of flexible robotic catheters enables “assisted navigation” and brings automation to endovascular navigation in an in vitro study
(2018)Objective: Combining three-dimensional (3D) catheter control with electromagnetic (EM) tracking-based navigation significantly reduced fluoroscopy time and improved robotic catheter movement quality in a previous in vitro ... -
Evaluation of Velocity Estimation Methods Based on Their Effect on Haptic Device Performance
(2018)This paper comparatively evaluates the effect of real-time velocity estimation methods on the passivity and fidelity of virtual walls implemented using haptic interfaces. Impedance width or Z-width is a fundamental measure ... -
Aorta zero-stress state modeling with T-spline discretization
(2018)The image-based arterial geometries used in patient-specific arterial fluid–structure interaction (FSI) computations, such as aorta FSI computations, do not come from the zero-stress state (ZSS) of the artery. We propose ... -
Effects of Assist-As-Needed Upper Extremity Robotic Therapy after Incomplete Spinal Cord Injury: A Parallel-Group Controlled Trial
(2017)Background: Robotic rehabilitation of the upper limb following neurological injury has been supported through several large clinical studies for individuals with chronic stroke. The application of robotic rehabilitation ... -
Sparse and low-rank methods in structural system identification and monitoring
(2017)This paper presents sparse and low-rank methods for explicit modeling and harnessing the data structure to address the inverse problems in structural dynamics, identification, and data-driven health monitoring. In particular, ... -
Nonlinear rocking of rigid blocks on flexible foundation: analysis and experiments
(2017)Primarily, two models are commonly used to describe rocking of rigid bodies; the Housner model, and the Winkler foundation model. The first deals with the motion of a rigid block rocking about its base corners on a rigid ... -
Persistent anomalies of the extratropical Northern Hemisphere wintertime circulation as an initiator of El Niño/Southern Oscillation events
(2017)Climates across both hemispheres are strongly influenced by tropical Pacific variability associated with the El Niño/Southern Oscillation (ENSO). Conversely, extratropical variability also can affect the tropics. In ... -
A perspective on climate model hierarchies
(2017)To understand Earth's climate, climate modelers employ a hierarchy of climate models spanning a wide spectrum of complexity and comprehensiveness. This essay, inspired by the World Climate Research Programme's recent “Model ...
