High Performance Data Acquisition And Analysis Routines For The Nab Experiment, David Mathews
High Performance Data Acquisition And Analysis Routines For The Nab Experiment, David Mathews
Theses and Dissertations--Physics and Astronomy
Probes of the Standard Model of particle physics are pushing further and further into the so-called “precision frontier”. In order to reach the precision goals of these experiments, a combination of elegant experimental design and robust data acquisition and analysis is required. Two experiments that embody this philosophy are the Nab and Calcium-45 experiments. These experiments are probing the understanding of the weak interaction by examining the beta decay of the free neutron and Calcium-45 respectively. They both aim to measure correlation parameters in the neutron beta decay alphabet, a and b. The parameter a, the electron-neutrino correlation coefficient, is …
Industrial Control System Data Resiliency, Daniel A. Bovard
Industrial Control System Data Resiliency, Daniel A. Bovard
Boise State University Theses and Dissertations
This thesis identifies and fortifies against a critical vulnerability in industrial control system (ICS) security. A properly designed ICS security framework consists of a multi-layered approach starting with heavy fortifications in information technology and ending with control information of operational technology. Currently, ICS security frameworks lack visibility and place blind trust in devices at the lowest level of the control hierarchy. Attaining control data visibility at the lowest level of the control hierarchy is critical to increasing the resiliency of an ICS security posture. This thesis demonstrates how this data can be captured at the lowest level of the control …
Evaluate The Use Of Fpga Soc For Real Time Data Acquisition And Aggregate Micro-Texture Measurement Using Laser Sensors, Mudit Pradhan
Evaluate The Use Of Fpga Soc For Real Time Data Acquisition And Aggregate Micro-Texture Measurement Using Laser Sensors, Mudit Pradhan
Computer Science and Engineering Theses
Aggregate texture has been found to play an important role in improving the longevity of highways and pavements. Aggregates with appropriate surface roughness level have an improved bonding with asphalt binder and concrete mixture to produce a more durable road surface. Macro-texture has been found to effect certain other important features of the road surface for example, the skid resistance, flow of water on the surface and noise of the tyre on road. However, more research need to done to access the impact of surface texture at micro-meter level. Accurate measurement of the micro-texture at high resolution and in real-time …
Tooling Data Collection System, Judith S. Brown
Tooling Data Collection System, Judith S. Brown
Regis University Student Publications (comprehensive collection)
This paper provides supporting documentation for the development and implementation of a Tooling Data Collection System. The project replaced a primitive Microsoft Excel log sheet. The original workstation for the data acquisition was a standalone system with limited access to the corporate network information and engineering resources. The need for a system revision and upgrade escalated due to the increasing prices of raw materials for component stamping. Refining this process to minimize the scrap generated was the main objective of the Tooling Data Collection System. The intent was for the information to provide the engineers with a mechanism to reduce …
Automatic Target Cueing Of Hyperspectral Image Data, Terry A. Wilson
Automatic Target Cueing Of Hyperspectral Image Data, Terry A. Wilson
Theses and Dissertations
Modern imaging sensors produce vast amounts data, overwhelming human analysts. One such sensor is the Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) hyperspectral sensor. The AVIRIS sensor simultaneously collects data in 224 spectral bands that range from 0.4µm to 2.5µm in approximately 10nm increments, producing 224 images, each representing a single spectral band. Autonomous systems are required that can fuse "important" spectral bands and then classify regions of interest if all of this data is to be exploited. This dissertation presents a comprehensive solution that consists of a new physiologically motivated fusion algorithm and a novel Bayes optimal self-architecting classifier …
