Water, salt water and alkaline solution uptake in epoxy thin films
(WileyJournal of Applied Polymer Science, 2013-05-10)
As a means of characterizing the diffusion parameters of fiber reinforced polymer (FRP) composites within a relatively short time frame, the potential use of short term tests on epoxy films to predict the long-term behavior ...
Anti-self-dual fields and manifolds
(University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2013-04-30)
In this thesis we study anti–self–duality equations in four and eight dimensions on manifolds of special Riemannian holonomy, among these hyper–Kähler,
Quaternion–Kähler and Spin(7)–manifolds.
We first consider the ...
Extremal and probabilistic bootstrap percolation
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2013-11-12)
In this dissertation we consider several extremal and probabilistic problems in bootstrap percolation on various families of graphs, including grids, hypercubes and trees. Bootstrap percolation is one of the simplest ...
Maximum likelihood parameter estimation in time series models using sequential Monte Carlo
(University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsStatistical LaboratoryDarwin College, 2013-06-11)
Time series models are used to characterise uncertainty in many real-world dynamical phenomena. A time series model typically contains a static variable, called parameter, which parametrizes the joint law of the random ...
Automorphisms of free products of groups
(University of CambridgeDepartment of Pure Mathematics and Mathematical Statistics, 2013-02-05)
The symmetric automorphism group of a free product is a group rich in algebraic structure and with strong links to geometric configuration spaces. In this thesis I describe in detail and for the first time the (co)homology ...
Essays on electricity market reforms: a cross-country applied approach
(University of CambridgeJudge Business School, 2013-06-11)
In the last two decades, more than half of the countries in the world have introduced a reform process in their power industries and billions of dollars have been spent on liberalizing electricity markets around the world. ...
Analysis of amorphous indium-gallium-zinc-oxide thin-film transistor contact metal
(AIP Publishing LLCApplied Physics Letters, 2013-04-15)
It is widely reported that threshold voltage and on-state current of amorphous indiumgallium-
zinc-oxide bottom-gate thin-film transistors is strongly influenced by the choice of
source/drain contact metal. Electrical ...
Gas-sensitive holographic sensors
(University of CambridgeDepartment of Chemical Engineering and BiotechnologyInstitute of Biotechnology, 2013-04-16)
Holographic sensors are photonic layered structures contained in analyte sensitive lms that upon illumination produce monochromatic reflections (λ). The present work reports the fabrication of oxygen and ammonia sensors ...
Automatic induction of verb classes using clustering
(University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2013-04-30)
Verb classifications have attracted a great deal of interest in both linguistics and natural language processing (NLP). They have proved useful for important tasks and applications, including e.g. computational lexicography, ...
