Distances Between Species in Food Webs: Evaluating Alternative Metrics' Predictive Power
<p>The complexity of ecological systems makes it difficult to predict how one species will react to the disturbance of another. Complex systems of species’ interactions can be described as ecological networks. One way in which ecological networks can give information concerning one species’ …

Alternative metrics for measuring heating trends, with possible connections between the surface and troposphere
… the surface and troposphere. Continued work with alternative heating metrics will increase understanding of microclimate influences and surface-troposphere connections.

Creating a Metric to Measure Software Flexibility in Object-Oriented Programming
… The metric was evaluated by comparison to alternative metrics and through user feedback.

Improvements to power system dynamic load model parameter estimation
… the computational burden. We then investigate alternative metrics for defining the difference between two time series, because the Euclidean distance was shown to be inadequate.

Quantifying a Range of Global Air Pollution Projections and Health Impacts under the Paris Agreement’s Temperature Targets
… health impacts, and broader sustainability metrics. This thesis responds to these needs by developing a new Tool for Air Pollution Scenarios (TAPS) and applying it to example policy effects on emissions, health impacts, and alternative metrics that are consistent with a stock-based …

Defining, measuring and regulating energy security
… about the definition of energy security and the metrics that could be used to measure the efficiency of different policies. As a result of this, it may be that both a political intervention in one direction and an intervention in the opposite direction could be justified on grounds of energy …

Hybrid solar-fossil fuel power generation
… fuel simultaneously, thus excluding the viable alternative of solar thermal plants which use fossil fuels as backup. The review is divided into three main sections: performance metrics, the different concentrated solar receiver technologies and their operating conditions, and the different …

Enhancing the Sustainability of Aluminium Production and Products
… is limited, prompting further investigation into alternative metrics. Subsequent chapters shift the focus to the hot forming of 6xxx series aluminium alloys. Chapter 4 details lab-scale experiments on 6082.50 and two 6110 alloy variants, including finite element modelling and constitutive data …

Identifying the Invisible Impact of Scholarly Publications: A Multi-Disciplinary Analysis Using Altmetrics
The field of ‘altmetrics’ is concerned with alternative metrics for the impact of research publications using social web data. Empirical studies are needed, however, to assess the validity of altmetrics from different perspectives. This thesis partly fills this gap by exploring the suitability and …

Connectivity, metapopulation dynamics, and genetic structure of tiger salamanders in a heterogeneous landscape
… better predictor of occupancy and turnover than metrics based on Euclidean distance or expert opinion. Occupancy and colonization probabilities were related positively to connectivity and negatively to fish presence. Extinction probability was related positively to fish presence, but extinction …

The development and drivers of the impact advantages of open access research
… 2010–23, the study examines OAAs across multiple metrics. These include journal citations, and six altmetric data sources, being citations from patents, Wikipedia, policy documents, and mentions on Twitter, in news, and in blogs. Analyses are segmented by publication year, time since publication, …
