System Non-Linearities Induced by Skyhook Dampers

Shock and Vibration, 2001
The nonlinearities induced by skyhook dampers are studied experimentally and analytically using a single degree of freedom base-excited system that is representative of the systems that such dampers are often used in. The experimental results are used to

SimpleTrack: Rethinking and Improving the JDE Approach for Multi-Object Tracking

Sensors, 2022
Joint detection and embedding (JDE) methods usually fuse the target motion information and appearance information as the data association matrix, which could fail when the target is briefly lost or blocked in multi-object tracking (MOT).

A Hybrid Control Policy for Semi-Active Vehicle Suspensions

Shock and Vibration, 2003
Various control policies, such as skyhook and groundhook control, have often been considered for semi-active vehicle suspensions. Past studies have shown the performance limitations of these policies, as well as others that have been considered for ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

An Evaluation of Magneto Rheological Dampers for Controlling Gun Recoil Dynamics

Shock and Vibration, 2001
The application of magneto rheological dampers for controlling recoil dynamics is examined, using a recoil demonstrator that includes a single-shot 50 caliber BMG rifle action and a MR damper.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
