A study of the stability of an electrically heated single channel, forced convection horizontal system was conducted by using Freon-11 as the test fluid. Two major modes of oscillations, namely, density-wave type (high frequency) and pressure-drop type (low frequency) oscillations have been observed. The steady-state operating characteristics and stable and unstable regions are determined as a function of heat flux, exit orifice diameter and mass flow rate. Different modes of oscillations and their chara...
2-D Kinematics of the Shank and Foot Complex during Stance using Markerless Segmentation and Body-Segment Anatomical Axes Identification
Sürer, Elif; Della Croce, Ugo (2008-10-31)
In this work, a markerless motion capture method is proposed for the 2-D description of the movement of the shank and foot complex. The video sequences of subjects walking wearing socks or barefoot, were segmented isolating the moving regions from the background. Anatomical axes of a three-segment model of the shank and foot complex were identified using two different methods applied to the segmented images: 1) skeletonization and line detection ...
2-D analysis of Ge implanted SiO(2) surfaces by laser-induced breakdown spectroscopy
Yalcin, Serife; Oerer, Sabiha; Turan, Raşit (Elsevier BV, 2008-10-01)
2-D elemental distribution of Ge in silicon oxide substrates with differing implantation doses of between 3x10(16) cm(-2) and 1.5x10(17) cm(-2) has been investigated by Laser-induced Breakdown Spectroscopy (LIBS). Spectral emission intensity has been optimized with respect to time, crater size, ablation depth and laser energy. Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM) coupled with Energy-Dispersive X-Ray Spectroscopy (EDX) have been utilized to obtain crater depth, morphology and ...

A two-point, aerodynamic design method is presented that improves the aerodynamic performance of transonic airfoils over a range of the flight envelope. It couples an Euler flow solver and a numerical optimization tool. The major limitation of single-point design is the poor off-design performance. Two-point design is used to extend the optimized performance range over more of the desired flight envelope. The method is applied to several transonic flow design points, and the results are compared to sing...
