The research of cavitation in narrow gap flows, e.g., lubrication films journal bearings or squeeze film dampers, is a challenging task due to spatial restrictions combined with high time-resolution. Typically, the thickness range few microns and characteristic time for bubble generation collapse less than milliseconds. authors have developed bearing model experiment, which designed according s...

We demonstrate plasmonic lithography with an optical contact probe to achieve high speed patterning without external gap distance control between the probe and the photoresist. The bottom surface of the probe is covered with a 10 nm thickness silica glass film for the gap distance control and coated with self-assembled monolayer (SAM) to reduce friction between the probe and the photoresist. We...

Digital photography of cavitation in narrow gap flows, e.g., lubrication films journal bearings or squeeze film dampers, demands a high time-resolution and solution to approaching the particular spatial restrictions. Typically, thickness is range few microns characteristic time for vapor bubble generation collapse about one millisecond, respectively. The authors have developed Journal Bearing M...

The UCF driving simulator, housed in the Center for Advanced Transportation Systems Simulation (CATSS) laboratory, is a high fidelity simulator with access to an expansive virtual driving environment. It consists of a Saturn cab, motion base, scenario editor, operators console and Application Programmer Interface (API) for reading real-time data. The data includes driver inputs, namely steering...

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of ana...

Multi-commodity flows over time exhibit the non-intuitive property that letting flow wait can allow us to send flow faster overall. Fleischer and Skutella (IPCO 2002) show that the speed-up through storage is at most a factor of 2, and that there are instances where the speed-up is as large as a factor of 4/3. We close this gap by presenting a family of instances for which the speed-up factor t...
