The quality of continuous cast steel is greatly affected by fluid flow in the mold region, especially involving transient phenomena and the transport of inclusion particles. As part of a long-term effort to develop and apply comprehensive models of these and other phenomena, this paper reports on studies to evaluate the relative accuracy of models of three different fluid flow phenomena in cont...

CERN, Meyrin, Switzerland Time-of-Flight PET (TOFPET) is likely to bring a significant improvement in PET image quality that could have a high impact in PET/MR acquisition and image reconstruction procedures. Silicon photomultipliers (SiPM) are known to be compatible with high magnetic fields. However, commercial SiPMs do not take advantage of their digital nature and are working in an analog m...

The transient bubble behavior was experimentally investigated to fundamentally understand the transient motion of gas bubbles in freely bubbling fluidized beds, simulating the FBC systems. Due to the oversimplified traditional two phase flow model concepts developed and most of the related numerous experimental works from 1960s to 1980s, the transient bubble behaviors could not have received du...

A one–dimensional, transient and thermal degradation model for predicting responses of composite materials when are exposed to the fire is presented. The presented model simulates ablation of composites with different layers of materials and considers material properties as functions of temperature. The reactions are modeled by using Arrhenius-type parameters and density-temperature diagram...

Prediction of traffic is very crucial for its management. Because of human involvement in the generation of this phenomenon, traffic signal is normally accompanied by noise and high levels of non-stationarity. Therefore, traffic signal prediction as one of the important subjects of study has attracted researchers’ interests. In this study, a combinatorial approach is proposed for traffic signal...

We present an ellipsometric technique and ellipsometric analysis of repetitive phenomena, based on the experimental arrangement of conventional phase modulated ellipsometers ~PME! conceived to study fast surface phenomena in repetitive processes such as periodic and triggered experiments. Phase modulated ellipsometry is a highly sensitive surface characterization technique that is widely used i...

This paper describes a data mining approach for extracting enriched data from scientific data archives such as NASA’s Earth Observing System Data and Information System (EOSDIS) that are stored on slow access tertiary storage. This enriched data has significantly smaller volume than the original data, yet preserves sufficient properties of this data such that over time, many different users can...

In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...
