description: We obtain a phase diagram of the spin imbalanced Hubbard model on the Lieb lattice, which is known to feature a flat band in its single-particle spectrum. Using the BCS mean-field theory for multiband systems, we find a variety of superfluid phases with imbalance. In particular, we find four different types FFLO phases, i.e. superfluid phases with periodic spatial modulation. They differ by the magnitude and direction of the centre-of-mass momentum of Cooper pairs. We also see a large region of stable Sarma phase, where the density imbalance is associated with zero Cooper pair momentum. In the mechanism responsible for the formation of those phases, the crucial role is played by the flat band, wherein particles can readjust their density at zero energy cost. The multiorbital structure of the unit cell is found to stabilize the Sarma phase by allowing for a modulation of the order parameter within a unit cell. We also study the effect of finite temperature and a lattice with staggered hopping parameters on the behaviour of these phases.

description: We present 1.3 and 3.3 mm polarization maps of Orion-KL obtained with the BIMA array at approximately 4 arcsec resolution. Thermal emission from magnetically aligned dust grains produces the polarization. Along the Orion ``ridge'' the polarization position angle varies smoothly from about 10 degrees to 40 degrees, in agreement with previous lower resolution maps. In a small region south of the Orion ``hot core,'' however, the position angle changes by 90 degrees. This abrupt change in polarization direction is not necessarily the signpost of a twisted magnetic field. Rather, in this localized region processes other than the usual Davis-Greenstein mechanism might align the dust grains with their long axes parallel with the field, orthogonal to their normal orientation.

Self-healing organic/inorganic composites

Publisher: name: Imperial College London
Year: 2015

description: Nature provides us with amazingly complex and clever systems, structures and substances that make up the world we see around us. We can refer to nature, borrowing its ingenious solutions to solve engineering challenges or improve existing man-made materials. The process of assimilating real- world biological examples into technology is called “bio-inspiration,” and for many years scientists have been attempting to imitate the design of natural materials. This project seeks to mimic some of the complex architectures with outstanding properties found in nature: the shells of molluscs, with extraordinary toughness due to a highly hierarchical structure of platelets on the micro- and nano- scale, and human bone, with its ability to self-heal and regenerate its complex composite organic/inorganic microstructure after fracture. In this work it will therefore be investigated the effect of composite polymer/ceramic structures obtained via a manufacturing technique called freeze-casting, it is observed and optimised the role of the thin interface in self-healing organic/inorganic composites and the composition of the soft supramolecular phase and the inorganic phase is varied in order to obtain structures with properties closer to the behaviour of natural ones. The study couples interface and composite design with mechanical tests to determine interfacial adhesion in order to understand the factors that control the strength of the composite and the effectiveness and timescale of its self-healing. The same self-healing polymer is moreover used in the production of an innovative light composite exhibiting electrical conductivity and compression and flexion sensing capabilities in the attempt to mimic the outstanding properties of skin.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

Hydro-economic modelling of groundwater-fed irrigation
Creators: name: Foster, Timothy
Publisher: name: Imperial College London
Year: 2015

description: Expansion of groundwater-fed irrigation has enhanced agricultural productivity, while simultaneously causing large reductions in groundwater storage. Hydro-economic modelling provides a valuable tool for evaluating trade-offs between agriculture and aquifer sustainability. However, a central argument in this thesis is that the reliability of integrated analysis of groundwater systems may be affected by the failure to consider adequately the variables influencing field-level irrigation decisions and the dynamic aquifer responses to those choices. This thesis addresses this limitation of existing research through three main contributions to the literature. In Chapter 2, a new model of farmers’ individual field-level groundwater-fed irrigation decision making is developed. Innovations include the explicit consideration of the role of soil moisture in intraseasonal irrigation scheduling, and evaluation of the impacts of weather variability and well yield on crop production. Application to a case study in the High Plains region of the United States demonstrates that low well yields limit significantly irrigated area and demand for groundwater. Furthermore, it is shown that this important behavioural response can not be captured by existing models that do not consider instantaneous supply constraints imposed by well yield. In Chapter 3, a combination of empirical analysis of observation data, and numerical simulations using the model developed in Chapter 2, are conducted to generate insights about the feedbacks between groundwater and agriculture. Reductions in well yield are shown to have large negative impacts on the productivity of irrigation whereas, contrary to previous assumptions, the response of irrigation behaviour to increased groundwater pumping lifts is found to be minimal. Importantly, this result highlights the need for integrated models to consider a broader range of factors influencing the sustainability of agricultural groundwater use. In Chapter 4, a novel hydro-economic modelling framework is presented that integrates the model of farmers’ individual irrigation decision making with a distributed multi-scale groundwater flow model. The model extends the scope of existing research by using pump head-capacity curves to quantify the effect of changing aquifer storage on well yields. Advantages of the modelling framework for policy analysis in coupled agricultural groundwater systems are demonstrated. Specifically, it is shown that the long-term sustainability of irrigated agriculture is influenced by intraseasonal and interannual changes in well yield that depend on famers’ pump choice and expectations about future dynamic aquifer responses. Moreover, the model demonstrates that managing the rate of well yield decline may have positive long-term impacts on both agricultural production and farmer welfare that have not been recognised in previous research.

description: "Pinch points," singular features observed in (quasi-)elastic neutron scattering, are a widely discussed hallmark of spin liquids with an emergent gauge symmetry. Much less attention has been paid to "half moons," distinctive crescent patterns at finite energy, which have been observed in experiments on a number of pyrochlore magnets, and in a wide range of model calculations. Here we unify these two phenomena within a single framework, paying particular attention to the case of ordered, or field-saturated states, where pinch points and half moons can be found in bands of excitations above a gap. We find that half moons are nothing other than pinch points inscribed on a dispersing band. Molecular dynamics simulations of the kagome lattice antiferromagnet are used to explore how these bands evolve into the ground state and excitations of a classical spin liquid. We explicitly demonstrate that this theory can reproduce the pinch points and half moons observed in Nd$_2$Zr$_2$O$_7$.

The suitability of magnesium phosphate cement for uranium metal encapsulation
Creators: name: Montague, William
Publisher: name: Imperial College London
Year: 2014

description: Nuclear waste streams consist of a diversity of physical and chemical forms, requiring a toolbox approach in the application of materials to their disposal. Solid uranium metal wastes constitute a disposal challenge due to their tendency to oxidise, making encapsulation within cementitious waste packages for storage potentially troublesome. MKPC (Magnesium Potassium Phosphate Cement) is being considered as an alternative to Portland cement for U-metal encapsulation due to the potential for lower free water content, lower internal pH and the micro-encapsulation of radioactive isotopes as low-solubility phosphate minerals. In this work the development and characterisation of MKPCs optimised for U-metal encapsulation was undertaken. This included the investigation of MKPC property development under both near ambient and elevated temperature conditions, the performance of MKPC/U-metal wasteform corrosion trials utilising temperature elevation (to 30, 40 and 50 °C) for the acceleration of chemical kinetics, and assessment of the impact of dehydration treatments (at 50, 80 and 110 °C) on the cement properties. In general MKPC exhibited excellent processing and mechanical properties. Other significant outcomes of the work include, firstly, the determination that uranium corrosion rate dependencies in MKPC are dominated heavily by the presence of water over other chemical effects, with an anoxic activation energy of 68 ± 6 kJ/mol. Secondly, the development of a methodology for determining the bound water content of MKPC, which allowed the calculation of the extent of reaction. This enabled analysis yielding empirical strength-porosity and kinetic models of the material, capable of facilitating improved mix design for the tailoring of MKPC properties. Finally, the instability of the K-struvite matrix toward dehydration at temperatures of ≥ 72 °C has been recorded. The work concluded that MKPC has many properties which make it suitable as a general encapsulant, whilst being ultimately unsuitable for U-metal storage without further development around the reduction of water availability.

description: The width $ΔT$ of the deconfinement transition region is shown to influence strongly the flow structure in the (Landau-) hydrodynamical expansion of a quark-gluon plasma. For a sharp first order transition ($ΔT=0$) the mixed phase is rather long-lived, with a lifetime that has a maximum when the initial energy density is at the phase boundary between mixed and pure quark-gluon matter. For increasing $ΔT$, however, the lifetime decreases rapidly. Hadronic matter, however, remains long-lived as a consequence of the rapid change in the degrees of freedom in the transition region and the corresponding ``softening'' of the equation of state.

On Spectral and Temporal Variability in Blazars and Gamma Ray Bursts
Creators: name: Dermer, Charles D.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A simple model for variability in relativistic plasma outflows is studied, in which nonthermal electrons are continuously and uniformly injected in the comoving frame over a time interval dt. The evolution of the electron distribution is assumed to be dominated by synchrotron losses, and the energy- and time-dependence of the synchrotron and synchrotron self-Compton (SSC) fluxes are calculated for a power-law electron injection function with index s = 2. The mean time of a flare or pulse measured at photon energy E with respect to the onset of the injection event varies as E^{-1/2} and E^{-1/4} for synchrotron and SSC processes, respectively, until the time approaches the limiting intrinsic mean time (1+z)dt/(2 D), where z is the redshift and D is the Doppler factor. This dependence is in accord with recent analyses of blazar and GRB emissions, and suggests a method to discriminate between external Compton and SSC models of high-energy gamma radiation from blazars and GRBs. The qualititative behavior of the X-ray spectral index/flux relation observed from BL Lac objects can be explained with this model. This demonstrates that synchrotron losses are primarily responsible for the X-ray variability behavior and strengthens a new test for beaming from correlated hard X-ray/TeV observations.

Phase Transition in Evolutionary Games

description: The evolution of cooperative behaviour is studied in the deterministic version of the Prisoners' Dilemma on a two-dimensional lattice. The payoff parameter is set at the critical region $1.8 < b < 2.0$ , where clusters of cooperators are formed in all spatial sizes. Using the factorial moments developed in particle and nuclear physics for the study of phase transition, the distribution of cooperators is studied as a function of the bin size covering varying numbers of lattice cells. From the scaling behaviour of the moments a scaling exponent is determined and is found to lie in the range where phase transitions are known to take place in physical systems. It is therefore inferred that when the payoff parameter is increased through the critical region the biological system of cooperators undergoes a phase transition to defectors. The universality of the critical behaviour is thus extended to include also this particular model of evolution dynamics.

Investigations of Aspergillus fumigatus RNA silencing mechanisms and pathogenicity in the presence of dsRNA mycoviruses
Creators: name: Özkan, Selin
Publisher: name: Imperial College London
Year: 2014

description: Mycoviruses are a specific group of viruses that naturally infect and replicate in fungi. Aspergillus fumigatus, an opportunistic pathogen causing fungal lung diseases in humans and animals, is recently shown to harbour at least three different types of mycoviruses. RNA silencing mechanisms exist in fungi against mycoviruses and it is also known that A. fumigatus encodes all the proteins involved in RNA silencing, including Dicer and Argonaute homologues. Therefore, it is anticipated that small interfering RNAs (siRNAs) are generated and silencing of viral dsRNAs occurs as seen with other mycoviruses. This study compares the gene expression levels in isogenic lines of virus-free and virus-infected A. fumigatus. Eight different genes that play a role in RNA silencing were selected and analysed by quantitative PCR in order to determine whether the expression levels of these genes correlate with virus infection. To further evaluate the potential existence of siRNAs, small RNA profiles of virus-free and virus-infected isolates were compared using next generation sequencing. Virus-derived siRNAs were detected in the presence of three A. fumigatus virus infections. Moreover first miRNA-like candidates in A. fumigatus were identified. Additionally, the effects of mycoviruses on the pathogenicity of A. fumigatus were assessed using larvae of the greater wax moth Galleria mellonella. A. fumigatus uncharacterised virus was found to cause mild hypervirulence in A. fumigatus. To our knowledge this is the first study reporting the small RNA profiles of A. fumigatus isolates and also the interaction between mycoviruses and virulence of A. fumigatus.

Year: 2014

description: Aims: To study the effect of pre-existing maternal cardiac disease on cardiovascular function during pregnancy, and on obstetric and fetal/neonatal outcomes, and to investigate maternal risk factors for adverse events. Methods: Retrospective case note review. Results: Four hundred and eighty-nine pregnancies in 326 women were studied. Most pregnancies (50%) occurred in women with congenital heart disease. There were 4 maternal deaths, 6 stillbirths and 5 neonatal deaths. Cardiovascular events occurred in 7.4% of pregnancies, while obstetric and perinatal complications occurred in 34% and 30% of pregnancies respectively. Conclusions: Pregnancy in women with pre-existing heart disease continues to be associated with high rates of maternal and neonatal mortality and morbidity. This work highlights the importance of effective prepregnancy counselling and meticulous surveillance during pregnancy, delivery and the puerperium by an experienced multidisciplinary team. Additionally there is an urgent need for well-designed randomisedcontrolled trials to determine best practice.

An investigation into the roles of water, sanitation, and hygiene in the control of schistosomes and other helminths
Creators: name: Grimes, Jack Edwin Thomas
Publisher: name: Imperial College London
Year: 2015

description: Schistosomes (primarily Schistosoma mansoni, S. haematobium, and S. japonicum) and soil-transmitted helminths (STHs: Ascaris lumbricoides, Trichuris trichiura, and hookworms) are prevalent parasites in many tropical countries. Their life cycles suggest that water, sanitation, and hygiene (WASH) might reduce their transmission. However, this field has suffered from a lack of rigorous studies with sufficient statistical power. A systematic review and meta-analysis determined that people with access to safe water and adequate sanitation have significantly lower odds of schistosome infection, although there was a risk of socioeconomic confounding (that is, people of higher socioeconomic status having better WASH and being protected from infection for other reasons). A more qualitative review identified many sources of complexity and non-linearity between WASH exposures and schistosome infection outcomes. Next, in a survey in and around 30 schools in southern Ethiopia, children were tested for the parasites, and school-, household-, and child-level WASH facilities and practices were assessed. Child- and household-level sanitation risk factors were compared with hookworm infection (the other helminths being very rare), but no significant associations were found. Finally, a school-level WASH survey was integrated into an Ethiopian national mapping programme for schistosomes and STHs, and data were collected from 1,645 schools. School-level scores were constructed, reflecting exposure to potentially schistosome-infested water during the collection of water for school, and the adequacy of school sanitation and hygiene facilities. These were compared with school-level arithmetic mean infection intensities for S. mansoni and the STHs, using Kendall's τb. Statistically significant associations were found for water and S. mansoni, sanitation and A. lumbricoides, and hygiene and hookworm, suggesting that these are the WASH elements best suited to the control of the respective parasites.

description: We have made a survey of heavy-to-heavy and heavy-to-light nonleptonic heavy baryon two-body decays and have identified those decays that proceed solely via $W$-boson emission, i.e. via the tree graph contribution. Some sample decays are $Ω_{b}^{-}\toΩ_{c}^{(*)0}ρ^{-}(π^{-}),\, Ω_{b}^{-}\toΩ^{-}J/ψ(η_{c}),\, Ξ_{b}^{0,-}\toΞ^{0,-}J/ψ(η_{c}),\, Λ_{b}\to ΛJ/ψ(η_{c}),\, Λ_{b}\to Λ_{c} D_{s}^{(\ast)},\, Ω_{c}^{0}\toΩ^{-}ρ^{+}(π^{+})$, and $Λ_c \to p ϕ$. We make use of the covariant confined quark model previously developed by us to calculate the tree graph contributions to these decays. We calculate rates, branching fractions and, for some of these decays, decay asymmetry parameters. We compare our results to experimental findings and the results of other theoretical approaches when they are available. Our main focus is on decays to final states with a lepton pair because of their clean experimental signature. For these decays we discuss two-fold polar angle decay distributions such as in the cascade decay $Ω_{b}^{-}\toΩ^{-}(\to Ξπ,ΛK^{-})+J/ψ(\to \ell^{+}\ell^{-})$. Lepton mass effects are always included in our analysis.

Seismic reflectivity and impedance inversion in multichannel fashion
Creators: name: Wang, Ruo
Publisher: name: Imperial College London
Year: 2014

description: Seismic reflectivity inversion is an important step in both signal processing and quantitative interpretation since reflectivity contains the information of impedance and other elastic parameters. Conventional methods assume stratified media and perform deconvolution on seismic data trace by trace. However, when using these single-channel methods, the lateral coherency of the result may be affected when the input seismic traces have low signal-to-noise ratios (SNRs) or complex structures. In this thesis, the development of multichannel inversion algorithms will be investigated to improve the continuity of the reflectivity profiles and suppress the noise. An example of a widely-used seismic reflectivity inversion method that is applied to single-channel seismic trace is the basis pursuit method. In this thesis, an FX prediction filter is incorporated with the conventional BP method, to investigate the potential benefit of multichannel implementation. Since the dictionary used in BP is huge in size, the matrix operations are very time consuming, yielding a long overall computational time. To improve the efficiency, a GPU-accelerated basis pursuit method is further implemented under CUDA architecture. Numerical results with the same accuracy are obtained and a speedup factor up to 145 for the whole process has been achieved. To implement a multichannel reflectivity inversion, the curvelet transform is employed. A comparative study on the performance of the curvelet deconvolution with two other widely used methods, the least-squares method and Lp-norm deconvolution, is further conducted. Since the deconvolution based on the curvelet transform offers a good trade-off between the lateral continuity and sparseness, the curvelet deconvolution result is used as the initial model to enhance the Lp-norm deconvolution. Numerical results show that the lateral continuity of the spiky reflectivity profile can be further improved. Moreover, I develop a proper multichannel deconvolution method based on the Cauchy constraint. In this algorithm, a multichannel prediction operator is integrated into the iteration process. In this way, the information of the adjacent traces is exploited during the inversion procedure. This method can provide results with improved lateral coherency, better structure characterisation ability and lower residual energy ratio. I also develop two modified processes based on the original Cauchy constrained multichannel method. These two modifications can give better quality for the reflectivity inversion results, when compared with the original algorithm. Finally, using a similar concept as the multichannel deconvolution method with the Cauchy constraint, I apply the multichannel inversion algorithm to seismic impedance inversion, with the input reflectivity series obtained from the previous inversion steps. Numerical results show impedance profiles with better structure identification and lateral continuity.
The Colour-Magnitude Relation as a Constraint on the Formation of Rich Cluster Galaxies

description: In this paper, we examine the role that the colour-magnitude relation (CMR) can play in constraining the formation history of rich cluster galaxies. Firstly, we consider the colour evolution of galaxies after star formation ceases. We show that the scatter of the CMR places a strong constraint on the spread in age of the bulk of the stellar population. However, although the bulk of stars must be formed in a short period, continuing formation of stars in a fraction of the galaxies is not so strongly constrained. We examine a model in which star formation occurs over an extended period of time in most galaxies. An extension of this type of star formation history allows us to reconcile the small present-day scatter of the CMR with the observed blue galaxy fractions of intermediate redshift galaxy clusters. Secondly, the CMR can also be used to constrain the degree of merging between pre-existing stellar systems. This test relies on the slope of the CMR. We show that random mergers between galaxies very rapidly remove any well-defined CMR. However, we prefer to examine the merger process using a self-consistent merger tree. In such a model there are two effects: massive galaxies preferentially merge with systems of similar mass; and the rate of mass growth is considerably smaller than for the random merger case. As a result of both of these effects, the CMR persists through a larger number of merger steps. The passive evolution of galaxy colours and their averaging in dissipationless mergers provide opposing constraints on the formation of cluster galaxies in a hierarchical model; but at the level of current constraints, a compromise solution appears possible.

description: We present the results of a study that uses numerical simulations to interpret observations of tidally disturbed satellites around the Milky Way. When analysing the simulations from the viewpoint of an observer, we find a break in the slope of the star count and velocity dispersion profiles in our models at the location where unbound stars dominate. We conclude that `extra-tidal' stars and enhanced velocity dispersions observed in the outskirts of Galactic satellites are due to contamination by stellar debris from the tidal interaction with the Milky Way. However, a significant bound population can exist beyond the break radius and we argue that it should not be identified with the tidal radius of the satellite. We also develop and test a method for determining the mass loss rate from a Galactic satellite using its extra-tidal population. We apply this method to observations of globular clusters and dwarf spheroidal satellites of the Milky Way, and conclude that a significant fraction of both satellite systems are likely be destroyed within the next Hubble time. Finally, we demonstrate that this mass loss estimate allows us to place some limits on the initial mass function (IMF) of stars in a cluster from the radial dependence of its present day mass function (PDMF).

Role of the cannabinoid system in nociceptive processing in primary sensory neurons

Publisher: name: Imperial College London

description: The endogenous ligand N-arachydonoylethanolamine (anandamide) is an important modulator of nociceptive processing in primary sensory neurons (PSN), because it activates both the excitatory transient receptor potential vanilloid type 1 ion channel (TRPV1) and the inhibitory cannabinoid type-1 (CB1) receptor, which are co-expressed in PSN and plays a pivotal role in the development and maintenance of pain associated with peripheral pathologies. However, the mechanisms involved in the anandamide-mediated modulation of nociceptive processing in PSN are not well understood. Here, we studied some important aspects of anandamide-mediated signaling in PSN. We found that multiple anandamide-synthesising pathways are present in PSN. The only Ca2+-sensitive anandamide-synthesising enzyme, Nacylphosphatidylethanolamine phospholipase D (NAPE-PLD), exhibits a high degree of co-expression with TRPV1, the CB1 receptor and the main anandamide-hydrolysing enzyme, fatty acid amid hydrolase. Spinal nerve injury, but not inflammation significantly alters this expression pattern. Although, the excitatory effect of anandamide is mediated by TRPV1 in PSN, not all TRPV1- expressing cells respond to anandamide. Blocking or deleting the CB1 receptor significantly reduces anandamide responsiveness of TRPV1, and PSN either express TRPV1 and the CB1 receptor in segregation or in close association. Cultured spinal microglia, in addition to PSN, also synthesise anandamide and that synthesis may depend on the activation state of spinal microglia and involve the activity of phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase 1 (Inpp5). 3 Our findings support the view that anandamide-mediated signalling may occur through autocrine mechanisms in PSN, and indicate that nerve injury may induce deregulation of that signalling which may contribute to the development of neuropathic pain. However, paracrine mechanisms, for example through anandamide synthesis in spinal microglia may also contribute to anandamide-mediated signalling, which is shaped, among others, by a complex crosstalk between the CB1 receptor and TRPV1. Finally, our findings suggest that NAPE-PLD and Inpp5 might be targets for future analgesics.

description: We investigate correlated insulating states in magic-angle twisted bilayer graphene (TBG) by the exact diagonalization method applied to the extended Hubbard model with interaction parameters recently evaluated in the realistic effective model. Our model can handle the competing interactions among Wannier orbitals owing to their significant overlap, which is a crucial but overlooked aspect of the magic-angle TBG. We propose two candidates for the correlated insulating states: spin- and valley-ferromagnetic band insulator and the Dirac semimetallic state for two flavors with peculiar renormalization, where a flavor denotes a combined degree of freedom with spin and valley. One of the important consequences for the latter candidate is that it allows van Hove singularity near half-filling of the whole band structure (i.e. near the Dirac points) to play some role in superconductivity. The consistency between the two flavor degrees of freedom for the Dirac semimetallic state and the two-fold degeneracy of the Landau level observed in the experiment is also noteworthy.

Aperture correlation microscopy

Publisher: name: Imperial College London

description: Microscopy as applied to the biological sciences has benefited tremendously in the last 50 years from the invention of optically sectioning microscopes. Many techniques for microscopy developed recently offer super-resolved imaging, but often at the cost of light efficiency, signal, acquisition speed or significant amounts of money. This thesis investigates further development of aperture correlation microscopy: a cheap, light-efficient, wide-field, optically sectioning, video-rate imaging technique until now incapable of super-resolution. An aperture correlation microscope was constructed, using a geometry consisting of 2 separate cameras permitting a larger field size than previous spinning disk aperture correlation systems. This microscope, operating at 16Hz (limited by the cameras) was then tested by imaging different samples and found to match reasonably well to the theory, while producing very clear images of biological samples. In order to power this aperture correlation microscope, an image registration algorithm must first register the frames from both cameras. We present a high-speed image registration algorithm suitable for fixed deformations, where a calibration pattern can first be imaged, by leveraging the graphics processing unit. In testing, this registration algorithm is capable of framerates of over 200Hz on modest hardware. A reflection correlation microscope was also constructed and characterised, operating at an illumination wavelength of 405nm, representing an advance into the UV for this technique. Synchronisation of camera acquisition and disk rotation allow for fast acquisition from a single camera. Measurements of its axial resolution match closely to the theory for 4 different illumination pattern pitches. Z-Stacks of transistor and Photovoltaic cell samples were taken in order to demonstrate this system's viability for imaging semiconductor devices. Finally, a novel type of aperture correlation microscope capable of super-resolution is designed and characterised, leveraging coherent illumination. It is demonstrated how tailoring the spatial frequencies present in the aperture mask can result in enhancement of high frequency information up to twice the diffraction limit. Transfer functions are measured, and found to match reasonably well with theory. Lateral resolution improvement of 1.5 times over conventional microscopy is seen here, paving the way for a new, highly efficient super-resolving microscope.
