Calibration of cosmogenic 36Cl production rates from Ca and K spallation in lava flows from Mt. Etna (38?N, Italy) and Payun Matru (36?S, Argentina)
(2011)Published cosmogenic 36Cl production rates from Ca and K spallation differ by almost a factor of 2. In this paper we determine production rates of 36Cl from Ca and K in samples of known age containing little Cl. Ca-rich ... -
A Condition-Based Maintenance Strategy for Heterogeneous Populations
(2014)This paper develops a maintenance strategy, called inspection-replacement policy, to cope with heterogeneous populations. Burn-in is the procedure by which most of the defective products in a heterogeneous population can ... -
Considerations on the UK Re-Arrest Hazard Data Analysis (How Model Selection Can Alter Conclusions for Policy Development)
(2011)The offence risk posed by individuals who are arrested, but where subsequently no charge or caution is administered, has been used as an argument for justifying the retention of such individuals? DNA and identification ... -

Continuous-Observation Partially Observable Semi-Markov Decision Processes for Machine Maintenance
(2017)Partially observable semi-Markov decision processes (POSMDPs) provide a rich framework for planning under both state transition uncertainty and observation uncertainty. In this paper, we widen the literature on POSMDP by ... -
Danger! men at work: a study of the underepresentation of women in third-level engineering

DCF: An Efficient and Robust Density-Based Clustering Method
(2021)Density-based clustering methods have been shown to achieve promising results in modern data mining applications. A recent approach, Density Peaks Clustering (DPC), detects modes as points with high density and large ... -
Decision-theoretic approaches to display strategies in content based image retrieval
(2004)In this report we continue development of a Bayesian CBIR system by considering the issue of an image display strategy. This is a decision problem and so within the Bayesian paradigm is to be solved by decision theory. ... -
Degradation-Based Maintenance Using Stochastic Filtering for Systems under Imperfect Maintenance
(2015)The stationaryWiener process is widely used in modeling degradation processes, mainly due to the existence of an analytical expression of the first hitting time distribution. However, it is only appropriate for modelling ... -
Dependent Gaussian mixture models for source separation
(2012)Source separation is a common task in signal processing and is often analogous to factor analysis. In this study, we look at a factor analysis model for source separation of multi-spectral image data where prior information ... -
Double Markov random fields and Bayesian image segmentation
(IEEE, 2002)Markov random fields are used extensively in modelbased approaches to image segmentation and, under the Bayesian paradigm, are implemented through Markov chain Monte Carlo (MCMC) methods. In this paper,we describe a ... -
The effects of Flare Definitions on the Statistics of Derived Flare Distributions.
(2016)The statistical examination of solar flares is crucial to revealing their global characteristics and behaviour. Such examinations can tackle large-scale science questions or give context to detailed single-event studies. ... -
Estimating production test properties from test measurement data
(2011)A complex sequence of tests on components and the system is a part of many manufacturing processes. Statistical imperfect test and repair models can be used to derive the properties of such test sequences but require model ... -
Estimating redshift distributions using Hierarchical Logistic Gaussian processes
(2019)This work uses hierarchical logistic Gaussian processes to infer true redshift distributions of samples of galaxies, through their cross-correlations with spatially overlapping spectroscopic samples. We demonstrate that ... -
Estimation of asymmetry in physics
(IEEE, 1996)The notion of asymmetry arises in many physical experiments, being a natural expression of the relative difference between two quantities. In this paper, we discuss the estimation of asymmetries between the rates of two ... -
Exponential family mixed membership models for soft?clustering of multivariate data
(2016)For several years, model-based clustering methods have successfully tackled many of the challenges presented by data-analysts. However, as the scope of data analysis has evolved, some problems may be beyond the standard ... -
Facing extinction? Why men are not attracted to primary teaching

Factors influencing when species are first named and estimating global species richness
(2015)Estimates of global species richness should consider what factors influence the rate of species discovery at global scales. However, past studies only considered regional scales and/or samples representing <0.4% of all ... -
A fast Bayesian model for a latent radio signal
(2009)Abstract?This paper considers the use of a recently developed Bayesian statistical approximation technique that leads to very fast determination of highly accurate estimates for latent radio signal power. Following ... -
Forward-Stagewise Clustering: An Algorithm for Convex Clustering
(2019)This paper proposes an exceptionally simple algorithm, called forward-stagewise clustering, for convex clustering. Convex clustering has drawn recent attention since it nicely addresses the instability issue of traditional ...
