Using machine learning to derive insights from sports location data
… we present applications of machine learning to derive insights from location data in soccer and basketball. In each case, we chose a data representation that allows the models to discover the importance of particular features and patterns. We demonstrate how new quantitive metrics can be derived …

Using age of infection models to derive an explicit expression for Ro
Using a multiple stage age of infection model, we derive an expression for the basic reproduction number, Ro. We apply this method to find Ro in analogous treatment models. We find, in the model without treatment, Ro depends only on the mean infective period, and not on the infective distribution. …

Using the Viable System Model to Derive Methods for Developing Principles of Enterprise Architecture
Principles play an important role in Information Management (IM); this can be seen from the different principle-based IM standards, such as ISO/IEC 38500 for IT Governance. Also, in the various definitions of Enterprise Architecture (EA), principles are regarded as a pivotal element. However, …

Intracellular peptide library screening to derive inhibitors of Parkinson's disease associated α-synuclein aggregation
Aggregation of α-synuclein (α-syn) into toxic fibrils is a pathogenic hallmark of Parkinson’s disease (PD). This research aimed to develop peptides capable of inhibiting α-syn aggregation using a semi-rational design combined with a multiplexed intracellular Protein-fragment Complementation Assay …

Formal framework and tools to derive efficient application-level detectors against memory corruption attacks
… protect. The analysis results are also used to derive selective detectors which are guaranteed to detect a given attack model. We demonstrate the methodology by deriving application specific detectors which are guaranteed to detect all attacks where the attacker's goal is to corrupt the …

Using Multiplayer Differential Game Theory to Derive Efficient Pursuit-Evasion Strategies for Unmanned Aerial Vehicles
… of the research presented in this thesis is to derive algorithms that can enable multiple UAVs to reason about the movements of multiple ground targets and autonomously coordinate their efforts in real-time to ensure that the targets do not escape. By improving the autonomy of multivehicle …

A comparison of multiattribute decision-making techniques using an iterative procedure to derive a convergent criterion
The objectives of the dissertation are to: (1) deductively compare five commonly used multiattribute decision making techniques and clarify the meanings of weights and (2) empirically evaluate the effectiveness of the techniques. The five techniques are multiattribute utility theory (MAUT), …

Use of artificial neural network models to derive particle size distributions and their moments from chord length distributions
The objective of this study was to develop a method for in-lie measurement of a particle size distribution (PSD) of suspended solids and its moments. This was part of a wider study, the aim of which was to develop a system for controlling a crystallisation process. The control strategy to be used …

Fuzzy Expert Systems: A More Human-Based Approach for Sensorial Evaluation of Coffee-Bean Attributes to Derive Quality Scoring
… Association of America</em> cupping process to derive quality scoring when grading specialty coffees. With a fuzzy expert system the judge's perception could be better assisted with a collection of linguistically expressed terms instead of numbers (complementary terms acting as shapers of the …

Modeling nonlinear stochastic ocean loads as diffusive stochastic differential equations to derive the dynamic responses of offshore wind turbines
… equations (SDE) in a state space form to derive the response statistics of offshore structures, specifically wind turbines. Often, severe wind and wave systems are highly nonlinear and thus treatment as linear systems is not applicable, leading to computationally expensive Monte Carlo …

MapNexus : a framework to derive human intent from architectural space to enable context-aware information exchanges in a wireless intranet
… and preserves the user's anonymity as it derives the client's physical location implicitly. Such a framework permits a new type of context-aware web interaction based upon the logical "common sense" patterns that are specific to architectural interior spaces at a given time.

Development of an analytical method to derive hydrophobicity parameters for use as descriptors for the prediction of the environmental and human health risk of chemicals
There is a requirement to assess the safety of chemicals to both 'man' and the environment. Traditionally this was determined through the use of animal testing. However, there is an increased need to develop alternatives to animal testing for the determination of toxicity due to ethical and …

Analisis orientado a objetos de imágenes de teledetección para cartografia forestal : bases conceptuales y un metodo de segmentacion para obtener una particion inicial para la clasificacion = Object-oriented analysis of remote sensing images for land cover mapping : Conceptual foundations and a segmentation method to derive a baseline partition for classification
El enfoque comúnmente usado para analizar las imágenes de satélite con fines cartográficos da lugar a resultados insatisfactorios debido principalmente a que únicamente utiliza los patrones espectrales de los píxeles, ignorando casi por completo la estructura espacial de la imagen. Además, la …

1+1+2 covariant approach to gravitational lensing in f(R) gravity
… theories of gravity. Using this formalism, we derive equations for a static and spherically symmetric spacetime for general f(R) gravity. We apply these master eqautions to derive some exact solutions, which are used to gain insight on Birkhoff's theorem in this framework. Additionally, we …
