Ramp event analysis for western Missouri
… however variable winds that contain ramp events are not represented very accurately. To better understand variability in western Missouri a statistical analysis was conducted to identify ramp events in various capacities based on time and strength. 10 minute average wind speeds were …

Popular event analysis in social communities
… among web users. As a result, a popular topic or event can spread much faster than in the Web 1.0 age. Indeed, when searching for a recent popular event (e.g., Hurricane Irene or Toyota Recall) on Twitter, all the results returned on the first page are created within the past five minutes. In such …

Initiating Event Analysis of a Lithium Fluoride Thorium Reactor
… of this study is to perform an Initiating Event Analysis for a Lithium Fluoride Thorium Reactor (LFTR) as the first step of a Probabilistic Safety Assessment (PSA). The major objective of the research is to compile a list of key initiating events capable of resulting in failure of safety …

Evaluating Alpha Spending Functions Applied to Observational Time-to-Event Analysis
… (RCTs) to observational studies with time to event analyses. In these less structured environments, key design parameters such as the total number of events are often unknown, posing challenges for the standard implementation of sequential analysis methods.</p> <p> Through simulation studies, …

The UK wind regime - Observational trends and extreme event analysis and modelling
… is found to capture the same set of extreme events as an ensemble consisting of nine global centres (157-239) highlighting the value of using model physics perturbations at this range. A prominent ETC, Emma, then forms the basis of a high-resolution model sensitivity analysis using the …

Advances in Time-to-Event Analysis: Big Data Applications in Cancer Risk Prediction
… some of them, with a particular focus on Time-to-Event analysis. The Cox hazard model, one of the most widely used statistical tools in biomedicine, is extended to analyses for large-scale and high-dimensional data sets. Built on recent machine learning frame- works the approach scales readily to …

Machine learning for social event analysis : public perceptions during COVID-19 and collective violence in South Africa
… social phenomena. The computational analysis of the dataset provides a different perspective on the observed phenomena. The data provided on social media platforms allows users to communicate and engage in discourse without the restrictions that traditional surveys and polls sometimes …

Integration Of Multi-Sensory Earth Observations For Characterization Of Air Quality Events
In order to characterize air quality events, such as dust storms or smoke events from fires, a wide variety of Earth observations are needed from satellites, surface monitors and models. Traditionally, the burden of data access and processing was placed on the data user. These challenges of …

Mining intrusion detection alert logs to minimise false positives & gain attack insight
… Detection System (IDS) logs in security event analysis is crucial in the process of assessing, measuring and understanding the security state of a computer network, often defined by its current exposure and resilience to network attacks. Thus, the study of understanding network attacks …

Examining telecommunication industry efficiencies in light of regulatory reform
… of telecommunication industry regulation is an event analysis of the trend of the employee per access line efficiency correlated with the announcement of regulatory reforms. A significant relationship is demonstrated.

The role of the Tehran Bazaaris in protest events under the first government of Mosaddeq in Iran (29 April 1951 - 21 July 1952)
… of the first government of Mosaddeq. Protest event analysis is used to test the religious explanation and the economic explanation of the <em>bazaaris</em>’ political activities. The results reveal the rivalry among the Tehran <em>bazaaris</em> over the economic and political advantages. This …

A comparative study of dementia-related service provision and configuration in Canada
… were also examined through time using time-to-event analysis. Further, relationships between participants and services were described using social network analysis. The following services were analyzed: neuroimaging, depression-related, delirium-related, future planning, informal support, …

A Toxicological Analysis of Exposure Magnitude, Duration, and Frequency and the Significance for Monitoring and Management of Episodic Pollution Events
… and appropriate models were used to expand the analysis of organism effects to additional exposure scenarios. Ceriodaphnia dubia and fish population models were used to evaluate population level and even community level responses to intermittent disturbances. Effects at the population level …

Statistical Analysis of Treatment Compliance for Clinical Trials using Electronic Compliance Monitoring
… behaviour from real ECM data through statistical analysis of compliance rate, followed by a time-to-event analysis with respect to first noncompliance event. Then, using discrete event simulation and proportional hazards models we compare analyses using a fixed treatment covariate and time-varying …

Big data in power systems: a statistical approach on synchrophasor application
… is offline, such as model validation and post-event analysis. This thesis aims to provide a significantly different approach in the synchrophasor usage. Rather than considering synchrophasor data as extra sensor data that allows for enhancement of models, this thesis treats synchrophasor data …

Implementation of an airline recovery model in an event-based simulation
… bad weather or unscheduled aircraft maintenance events can have a significant impact on an airline's operations. The consequences of these disruptions are major costs to airlines, passengers and, ultimately, to the economy itself. In this thesis, the steps taken to implement an airline schedule …
