Chemical composition and pH of marine aerosols in the summer-time marine boundary layer of the Atlantic sector of the Southern Ocean
… constrain, in part because there are no direct methods to measure aerosol pH. The lack of observations in the remote clean atmosphere makes quantification of aerosol pH even more challenging. This dissertation aims to predict the spatial and temporal variation of aerosol pH and its drivers in …

Precision stationkeeping with azimuthing thrusters
… the optimization of thruster outputs uses an online method to minimize the amount of error. It simplifies necessary calculations by the assumption that the rotating thrusters are always parallel thus making the system holonomic. The scheme accommodates for limitations in actuator outputs, …

A New Method of Determining the Transmission Line Parameters of an Untransposed Line using Synchrophasor Measurements
… is of paramount importance. Traditional methods of determining transmission line parameters must take a large number of factors into consideration. It is difficult and in most cases impractical to include every possible factor when calculating parameter values. A modern approach to the …

Closed-loop control of spacecraft formations with applications on SPHERES
… times during an orbit. This thesis presents an online method for generating fleet-wide plans, using convex optimization techniques, that satisfy multiple objectives. The approach allows for minimum and balanced fuel usage, can position spacecraft in arbitrary configurations, and favors …

Goal Inference from Open-Ended Dialog
… agent is extremely certain about. We present an online method for embodied agents to learn and accomplish diverse user goals. While offline methods like RLHF can represent various goals but require large datasets, our approach achieves similar flexibility with online efficiency. We extract …

Biologically inspired goal directed navigation for mobile robots
… carried out in the literature by the offline method of linear regression, in this work we introduce a novel way of training these networks that is online using concepts from adaptive filters. This online method increases the adaptability of this system while significantly decreasing its memory …

CLASSIFIERS BASED ON A NEW APPROACH TO ESTIMATE THE FISHER SUBSPACE AND THEIR APPLICATIONS
In this thesis we propose a novel classifier, and its extensions, based on a novel estimation of the Fisher Subspace. The proposed classifiers have been developed to deal with high dimensional and highly unbalanced datasets whose cardinality is low. The efficacy of the proposed techniques has been …

Investigation of matching problems using constraint programming and optimisation methods
… the kidney exchange is inherently a stochastic online problem, first, we give a stochastic online method. This methos is more general and provides an expected value estimation that is correct within the limit of sampling errors. Sec- ond, we show that by taking into consideration a probabilistic …

Vision based methodology for evaluation of meat quality characteristics : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… of meat quality evaluation. Vision based methods have been shown to be an effective means for meat quality evaluation. At present there is no online method available in New Zealand to measure meat quality characteristics, but there is a real need to determine these characteristics as the …
