Design and development of an ultrafine particle reflection-time-of-flight mass spectrometer
(Texas A&M University, 2002)
The primary motivation for the research is to study the effect of small particles on global climate. The study can also help to understand the dynamics involved with gas to particle conversion, which is being debated to ...
Optical detection of air bubbles trapped in a micro-capillary pore using a laser interferometric backscatter technique
(Texas A&M University, 2002)
The laser interferometric backscatter technique has been used to detect the presence of air bubbles trapped inside a micro-capillary pore. A simple experimental setup consists of a low power He-Ne laser, micro-capillary ...
Increasing the robustness of the input-shaping method using adaptive control
(Texas A&M University, 2002)
Input-Shaping is a widely used method of suppressing residual vibrations in point-to-point motion of flexible bodies. It is easy to implement and gives good results if the dynamics of the system are known accurately. ...
Heat transfer characteristics of circular impinging jet arrays in an annular section with cross flow effects
(Texas A&M University, 2002)
Jet impingement has been shown to be an effective method for enhancing convective heat transfer. There are a variety of applications of impinging jets in industry, including tempering and shaping of glass, annealing of ...
Optimization of a dual acting, magnetically driven, linear actuator
(Texas A&M University, 2002)
In this study the geometry of a dual acting, magnetically driven, linear motion actuator will be optimized. This will be accomplished by modeling the system through a set of differential equations to be solved in Matlab. ...
Aerosol-to-Hydrosol Transfer Stages for use in bioaerosol sampling
(Texas A&M University, 2002)
Single-Jet and Multi-Jet Aerosol to Hydrosol Transfer Stages (AHTS) with cutpoints of 2 and 0.8 []m AD, respectively, were designed and evaluated. Both devices operate at nominal air sampling flow rate of 1 L/min, 0.1% ...
Specific grinding energy causing thermal damage in precision gear steels
(Texas A&M University, 2002)
This project is aimed at developing a better understanding of thermal damage caused by grinding of precision gear materials and also a model to predict the onset of burn in AISI 9310 gear steel. This study is concerned ...
Consolidation of zirconium-based metallic glass powder by equal channel angular extrusion
(Texas A&M University, 2002)
In this study, amorphous Zr₅₈.₅Nb₂.₈Cu₁₅.₆Ni₁₂.₈Al₁₀.₃ (Vitreloy 106a) gas-atomized powder was consolidated by equal channel angular extrusion (ECAE). Several copper cans were filled with the powder, vacuum encapsulated ...
On-line implementation of a fault diagnosis system for three-phase induction motors
(Texas A&M University, 2002)
Condition monitoring of electric machinery has received increased attention due to the advantages it offers in terms of productivity. Automation of the fault detection and diagnosis processes would not only allow for ...
Automatic Calibration of a Building Energy Performance Model and Remote Fault Detection For Continuous Commissioning Using a Global Optimization Program
(Texas A&M University, 2002)
Building simulation models have been used for many years to forecast and analyze a building's energy consumption. Over the past several decades, building energy simulation programs and input techniques have been developed ...
