Abstract:

Due to the enhanced level of national security currently required due to the possibility of terrorist attack, monitoring devices for trace levels of explosive materials are now of the upmost importance. One such method that offers a possible route towards the development of a system for the detection of such analytes is via an electrochemical regime, coupled to the use of disposable sensor technology. Within this study, the use of modified carbon screen-printed sensors for the detection and analysis of such analytes of importance has been investigated. The modification of the base carbon subst

Abstract:

<p> This thesis discusses the application of advanced digital signal and image processing techniques, particularly the technique known as super-resolution (SR), to enhance the imagery produced by cameras mounted on an airborne platform such as an unmanned aircraft system (UAS). SR is an image processing technology applicable to any digital, pixilated camera that is physically limited by construction to sample a scene with a discrete, <i><b>m x n</b></i> pixel array. The straightforward objective of SR is to utilize mathematics and signal processing to overcome this physical limitation of the <

Abstract:

Millimetre-wave radar in a missile seeker for the engagement of ground targets allows all-weather, day and night, surface imaging and has the ability to detect, classify and geolocate objects at long ranges. The use of a seeker allows intelligent target selection and removes inaccuracies in the target position. The selection of the correct target against a cluttered background in radar imagery is a challenging problem, which is further constrained by the seeker’s hardware and flight-path. This thesis examines how to make better use of the components of radar imagery that support target selecti

Exposure to air pollution can cause adverse health effects, may also adversely affect the central nervous system and affect cognitive performance.

A critical ability of any aircraft is to be able to detect potential collisions with other airborne objects, and maneuver to avoid these collisions. This can be done by utilizing sensors on the aircraft to monitor the sky for collision threats. However, several problems face a system which aims to use multiple sensors for target tracking. The data collected from sensors needs to be clustered, fused, and otherwise processed such that the flight control system can make accurate decisions based on it.

碩士<br>淡江大學<br>航空太空工程學系碩士班<br>93<br>This research develops a low cost three-axis electronic crash sensor for airborne application. The key elements of the crash sensor are two dual-axis MEMS technology based micro accelerometers. The crash sensor continuously monitors the acceleration of the air vehicle. An emergency activation signal will be engaged to activate the Emergency Locator Transmitter once a real crash is assured. In the design, the crash accident is assured if the acceleration exceeds 2.3 G and the velocity variation exceeds 1.4 m/sec. The data acquisition, reduction, crash con
