Atomic beam experiments are limited by intensity. Intensity limitations are specially critical in the measurements of metastable atoms, since their relative population is several order of magnitude smaller than the beam population. This thesis provides a method for increasing the intensity of metastable argon and neon beams effusing from a hot cathode, glow discharge by use of a longitudinal magnetic field. The argon and neon metastable atom intensities have been measured for a range of discharge pressure, voltage, and current for a magnetic field strengths from 0 to 31 mT. For both argon and

A cold cell (6 K) is filled with a buffer gas, such as helium, that exhibits sufficiently high vapour pressure for cryogenic applications. Hot molecules (150 to 300 K) enter the cell and therma

An analytical model of cracked composite beams vibrating in coupled bending-torsion is developed. The beam is made of fiber-reinforced composite with fiber angles in each ply aligned in the same direction. The crack is assumed open. The local flexibility concept is implemented to model the open crack and the associated compliance matrix is derived. The crack introduces additional boundary conditions at the crack location and these effects in conjunction with those of material properties are investigated. Free vibration analysis of the cracked composite beam is presented. The results indicate t

Abstract:

Laser-beam-induced-current (LBIC) is being investigated as a combined electro-optical (EO) alternative to individual electrical and optical based measurements of p-n junction photodiodes. The technique is non-destructive and employs a focused low-power laser beam that is scanned across the semiconductor surface, between two shorted ohmic contacts located at remote positions on either side of the scanned area. The LBIC image is then a two-dimensional map of the steady-state current-flow as a function of laser position. However, despite its simplicity, its application has thus far been limited t

Tenax-TA adsorbent tubes and a low flow rate pump were used to collect the coffee beans aroma. Then the adsorbent tube was submitted to TD-GC-MS for analysis. Different roasting conditions would give the coffee beans aroma various smells and taste characteristics. This is due to the complex chemical reactions occurred during the roasting process. 17 major components have been identified by GC-MS. R

碩士<br>國立高雄應用科技大學<br>精密模具與機械產研碩士外國專班<br>99<br>A computational fluid dynamics model used to understand the hydrodynamics of three phase fluidized bed is presented in this paper. In the present investigation, an attempt has been made to study the complex hydrodynamics of three phase fluidized bed; bed expansion, holdup of two phases, bed pressure drop, fluidized bed voidage and velocity profile. The model is developed by using the commercial CFD code Fluent 6.2. The drag model for simulating is used Gidaspow model. The main focus on for analyzing the results is on the column with 1.5m height and

Abstract:

The effect of the refraction of a laser beam propagating through three different phase objects, i.e. a laser produced plasma and two different gas media, is investigated in this thesis. It is shown that these effects have useful applications. As an introduction to the work performed, a basic discussion of the theory of light is given. In the first experimental study, the accuracy of using the Refractive Fringe Diagnostic, as a tool to determine the electron density profiles of laser produced plasmas, is investigated [Buccellato et al. (1992)]. A comparative study is performed between a

Abstract:

LIDAR, an acronym for LIght Detection And Ranging, is a system used for studying the scattering of laser light incident on a parcel of air. This thesis investigates the atmosphere above the Durban region using two atmospheric LIDARs, referred to, in this study, as the "old LIDAR" and the "new LIDAR". The old LIDAR was used in a campaign of observation from July to October 1997 in a study of aerosol concentrations over Durban. This thesis will focus on, among other things, the local aerosol profiles for low altitude (0 to 10 km) and high altitude (10 to 35 km). In particular, the focus w

Abstract:

Research capabilities in nuclear physics have greatly expanded in recent years with the availability of radioactive ion beams and exotic nuclei near the drip line. As a result, new phenomena are being discovered in areas of nuclear reactions and nuclear structure. This thesis work is focused on studies of reaction mechanisms of light weakly bound nuclei at energies near the Coulomb barrier, where nuclear structure influences nuclear reactions outcomes. Two strands towards this end were followed concurrently; the first, to develop a ra
