Signal processing techniques for ultrasonic inspection
… some of the limitations in present day techniques. Special interest has been given to ultrasonic examination techniques and the problems encountered when they are applied to thick welded plates. Some suggestions are given using signal processing methods. Chapter 2 treats the need for …

Advancing acoustography by multidimensional signal processing techniques
… is the investigation into multidimensional signal processing for acoustography. Acoustography is a novel inspection technique similar to x-ray. However, instead of using hazardous ionising radiation, acoustography is based on sound. Inspection data are intensity images of the interior of …

Signal Processing Techniques Applied to Biomedical Diagnostics
… (FWHT), and evaluate its ability to boost the signal-to-noise ratio of optical fluorescence signals. The LIA is designed to be resilient in challenging environments containing high/unpredictable ambient noise. We then develop two rapid diagnostic systems that pair this technology with …

GNSS Signal Processing Techniques for Spoofing Resiliency
… is a spoofing attack where the agent transmits signals with the same signal structure as GNSS signals, but they are modified to produce an incorrect navigation solution. Resiliency to these attacks is important for GNSS navigation. Two methods for GNSS resiliency are explored in this …

Fault detection in rotating machines by vibration signal processing techniques
… at an early stage. There are a large number of signal processing techniques that can be used in order to extract interesting information from a measured vibration signal. This study seeks to detect rotating machine defects using a range of techniques including synchronous time averaging, Hilbert …

Software packages performance evaluation of basic radar signal processing techniques
This dissertation presents a radar signal processing infrastructure implemented on scripting language platforms. The main goal is to determine if any open source scripted packages are appropriate for radar signal processing and if it is worthwhile purchasing the more expensive MATLAB, commonly used …
