The Flood Frog: An Autonomous Wireless Device For Flood Detection And Monitoring, Valerio Plessi Jan 2006

The Flood Frog: An Autonomous Wireless Device For Flood Detection And Monitoring, Valerio Plessi

Masters Theses

"Accurate real time monitoring is gaining critical importance in a broad range of domains. Of particular interest to this research is the development of monitoring and detection systems for environmental and structural phenomena. Transportation infrastructures, in particular bridges, provide examples for both categories. Flooding of low water bridges is one example of rapidly evolving environmental phenomena, while stress and vibration are structural phenomena in need of monitoring.

Early warning and advanced preparation for emergency are two of the most effective lines of defense against catastrophic events, where real time monitoring can facilitate containment and recovery efforts. The operating environment of …


Paleocene To Early Eocene Dinoflagellate Cyst Biostratigraphy In Southeast Nigeria And The Cote D'Ivoire-Ghana Transform Margin (Odp Site 959), Hernan Antolinez-Delgado Jan 2006

Paleocene To Early Eocene Dinoflagellate Cyst Biostratigraphy In Southeast Nigeria And The Cote D'Ivoire-Ghana Transform Margin (Odp Site 959), Hernan Antolinez-Delgado

Masters Theses

"This study represents a contribution to Early Paleogene biostratigraphy in the tropics where published studies are sparse in comparison with mid and high latitude regions. Data were derived from a comprehensive analysis of dinoflagellate cysts (dinocysts) in 45 samples from the Early Paleocene to Early Eocene interval at two localities in West Africa, namely Alo-1 well in the Anambra Basin, southeastern Nigeria, and Ocean Drilling Program Hole 959D (ODP Leg 159) in the Cote d'Ivoire-Ghana Transform Margin. Dinocyst recovery varied from very good to poor, and the specimens were commonly well preserved. The dinocyst data were calibrated with existing calcareous …


Comparison Of Combustion Sources And Measurement Techniques For Particulates Emitted From Engines And A Power Plant, Matthew F. Chandler Jan 2006

Comparison Of Combustion Sources And Measurement Techniques For Particulates Emitted From Engines And A Power Plant, Matthew F. Chandler

Masters Theses

"Sub-micron particulates emitted from various combustion sources have serious negative impacts on human health and the environment. It is essential to accurately characterize the physical properties of these particulates including size, shape, structure, and chemical composition in order to monitor, regulate, and model the various transport, toxic, optical, chemical, and deposition properties which dictate their harmful effects. This study consists of two related investigations involving the application of diagnostics methods to characterization and comparison of combustion generated particulate emissions from various sources. The first investigation includes the measurement of particulates emitted from a compression-ignition (diesel) engine using two independent measurement …


Model Checking Control Communication Of A Facts Device, David Andrew Cape Jan 2006

Model Checking Control Communication Of A Facts Device, David Andrew Cape

Masters Theses

"This thesis concerns the design and verification of a real-time communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to design and verify the correctness in the presence of these lost data frames under real-time constraints. This thesis describes a temporal verification that if the end processes do not detect that too many frames are lost, defined by comparison of error counters against given threshold values, then there will be a bounded delay between transmission of …


Direct Microstructure Deposition By Micromirror Direct Patterning And Laser Sintering Of Nanoparticles, Weiya Fang Jan 2006

Direct Microstructure Deposition By Micromirror Direct Patterning And Laser Sintering Of Nanoparticles, Weiya Fang

Masters Theses

"The emerging demand for low cost, medium volume production and flexible micro-fabrication techniques has been advanced by the development of MEMS and limitations of the existing technique. As a promising building block for future MEMS and IC industry, nanoparticles are attracting more and more attention due to their interesting electronic, catalytic and optical properties, which can be finely tuned by varying their size. A novel process for the manufacturing of functional microstructures by modulated laser direct patterning and curing of nanoparticles is presented.

The first part of the thesis aims to understand the possibility and process of using modulated laser …
