Rapidly sheared homogeneous stratified turbulence in a rotating frame
(2007)
Rapid distortion theory is applied to stratified homogeneous turbulence that is sheared in a rotating frame. Insight into the stabilizing and destabilizing effects of the combined stratification and frame rotation is gained ...
Complex effects in Large Eddy Simulations
(Springer, 2007)
Target cascading in vehicle redesign: A class VI truck study
(2002)
The analytical target cascading process is applied to the redesign of a U.S. class VI truck. Necessary simulation and analysis models for predicting vehicle dynamics, powertrain, and suspension behaviour are developed. ...
Wetting of doped carbon nanotubes by water droplets
(2005)
We study the wetting of doped single- and multi-walled carbon nanotubes by water droplets using molecular dynamics simulations. Chemisorbed hydrogen is considered as a model of surface impurities. We study systems with ...
Assignment of natural frequencies by an added mass and one or more springs
(2004)
The problem of assigning natural frequencies to a multi-degree-of-freedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...
Identification of hysteretic systems using the differential evolution algorithm
(Affiliation: Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United KingdomCorrespondence Address: Kyprianou, A.Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United Kingdomemail: Mep96Gak@sheffield.ac.uk, 1998)
In system identification, it is well-known that any non-linear in the parameters system, possesses a complicated error surface with many local minima. In this case the conventional algorithms, such as those based on least ...
A Frequency-Based Interpretation of Energy-Based Model Reduction of Linear Systems
(2016)
Various modeling techniques have been proposed in order to make modeling a more systematic procedure and to facilitate the development of modeling software that provide users, even experienced users, more ease when developing ...
Energy-based model reduction methodology for automated modeling
(2010)
In recent years, algorithms have been developed to help automate the production of dynamic system models. Part of this effort has been the development of algorithms that use modeling metrics for generating minimum complexity ...
First-passage study and stationary response analysis of a BWB hysteresis model using quasi-conservative stochastic averaging method
(1995)
The quasi-conservative stochastic averaging (QCSA) method is applied to a Bouc-Wen-Baber hysteretic system (BWB) under Gaussian white noise excitations. The stationary probability density of the system's response amplitude ...
Stress-mediated progression of solid tumors: effect of mechanical stress on tissue oxygenation, cancer cell proliferation, and drug delivery
(2015)
Oxygen supply plays a central role in cancer cell proliferation. While vascular density increases at the early stages of carcinogenesis, mechanical solid stresses developed during growth compress tumor blood vessels and, ...
