Design Methods for Remotely Powered Unmanned Aerial Vehicles
<p>A method for sizing remotely powered unmanned aerial vehicles is presented to augment the conventional design process. This method allows for unconventionally powered aircraft to become options in trade studies during the initial design phase. A design matrix is created that shows where, and if, …

Characterization of uncertainty in remotely-sensed precipitation estimates
… framework for characterizing uncertainties in remotely-sensed precipitation estimates. This characterization is a prerequisite if these estimates are to be used in hydrological models. Precipitation forcing is the primary source of uncertainty in surface hydrological models used for forecasting …

Machine learning for automatic classification of remotely sensed data
As more and more remotely sensed data becomes available it is becoming increasingly harder to analyse it with the more traditional labour intensive, manual methods. The commonly used techniques, that involve expert evaluation, are widely acknowledged as providing inconsistent results, at best. We …

AN INVESTIGATION OF REMOTELY SENSED URBAN HEAT ISLAND CLIMATOLOGY
Satellite remotely sensed temperatures are widely used for urban heat island (UHI) studies. However, the abilities of satellite surface and atmospheric data to assess the climatology of UHI face many unknowns and challenges. This research addresses the problems and potential for satellite remotely …

Mass spectrometric characterization of remotely charged amino acids and peptides
<p>Ion–molecule reactions in a flowing afterglow are used to examine the electronic structure of 3- and 4-pyridinylnitrene-n-oxide radical anions. Reactions with nitric oxide are generally similar to those reported previously for other aromatic nitrene radical anions. In particular, phenoxide …

Human and automatic control interaction with a remotely piloted vehicle
In this dissertation, we present results from a study on the performance of humans and automatic controllers in a general remote navigation task. The remote navigation task is defined as driving a vehicle with nonholonomic kinematic constraints around obstacles toward a goal. We conducted …

Spatial reasoning about remotely sensed data for drainage network mapping
In order to extract a drainage network from a LANDSAT scene of mountainous terrain, it is necessary to use an illumination model to separate the reflectance information from the topographic information in the LANDSAT data. From the reflectance information, visible stream segments can be detected. …
