Energy consistent nonlinear dynamic contact analysis of structures
Creators: name: Zolghadrzadehjahromi, Hamed
Publisher: name: Imperial College London
Year: 2015

description: This work is motivated by the need for a numerically stable dynamic contact algorithm, for use with finite element (FE) analysis including both material and geometric nonlinearities, which imposes the appropriate full kinematic compatibility between the interfaces of impacting boundaries during a persistent dynamic contact. Several methods were previously developed based on Lagrangian multipliers or penalty functions in an attempt to impose the impenetrability condition of dynamic contact analysis. Some of these existing algorithms suffer from lack of numerical stability, and most of them are incapable of accurately predicting the persistent contact force, hence they would not be suitable for frictional dynamic contact analysis. The numerical stability and energy conservation characteristics of conventional frictionless dynamic contact algorithms using Lagrangian displacement constraints and penalty functions are investigated in this thesis. Two energy controlling dynamic contact algorithms are proposed in conjunction with the well-known Newmark trapezoidal rule, namely, regularised penalty method and Lagrangian velocity constraint. Although energy consistent, the state of the art for these two methods is somewhat similar to the conventional displacement constraints in the sense that acceleration compatibility is not imposed when simulating problems featuring persistent dynamic contact. In this work, a novel and superior energy controlling-algorithm is proposed which overcomes the aforementioned shortcomings. The proposed DVA method enforces the displacement, velocity and acceleration compatibilities (referred to as DVA constraint in this work) between the impacting interfaces, which in contrast to existing algorithms can be used for FE analysis of problems exhibiting geometric and material nonlinearities. The advanced DVA method is devised such that the kinematic compatibilities at the interface are consistent with the solution for a continuous system without any special treatment in the time-integration or solution procedure of the penetrating interface boundaries. Furthermore, this can be achieved in conjunction with all of the prevalent implicit time-integration schemes such as the trapezoidal rule, midpoint rule, HHT-α and the most recently developed Energy-Momentum family of Methods. Finally, utilising the proposed dynamic contact algorithms, a novel multi-constraints node-to-surface dynamic contact element is formulated and programmed within a geometric and material nonlinear dynamic FE analysis software. Several verification examples of frictionless mechanical contact are presented to demonstrate the superiority and performance of the developed node-to-surface contact element in conjunction with the proposed DVA constraint as well as the Lagrangian velocity constraint, providing a robust and accurate solution procedure for highly nonlinear dynamic contact analysis.

description: The last several years have revealed information technology and scientific data to be important allies. However, the most important scientific ally is that which can assist in the complex task of identifying, collecting and treating the exponential amount of data added to the Web every day in the XXI century. Moreover, the volume of this data exceeds 2.5 x 1018 new bytes per day and arrives on the Web at a rapid speed. Thus, it is necessary to assess the veracity of these data and their value to decision-making. Although approximately 43% of the data are related to health and about one million scientific articles published per year are in the health field, it is important to think beyond trivial models to solve problems of local health with a global focus. Thus, this work aims to contribute to the reflection on the use of free tools as well as to discussions of collaborative and effective partnerships for action in the field of Public Health. This study shows opportunities to use open science for global health innovation, mainly, to the countries with difficulty in managing the problems of their ills. Open science in times of Big Data are much more agile than the old model of closed science, i.e., isolated groups that either did not share data or did share but at prices that were unaffordable for developing or underdeveloped countries. Technological development for new chemical entities can be facilitated by using the open science of the Scientific’s Big Data.

description: We use multiple scattering theory to evaluate the $Q^{2}$ dependence of the forward-backward asymmetry, $A_{z}$, of the missing momentum distribution in quasielstic $A(e,e'p)$ scattering, which is expected to be affected by color transparency. The novel features of our analysis are a consistent treatment of the structure of the ejectile state formed after absorption of the virtual photon by the struck proton and a careful evaluation of the background asymmetry induced by the nonvanishing real part of the proton-nucleon scattering amplitude. We find that the absolute magnitude of $A_{z}$ is dominated by this background at the $Q^{2}$'s attainable at the Continuous Electron Beam Accelerator Facility. However, the $Q^{2}$ dependence of the asymmetry is sensitive to the onset of color transparency, whose observation in high statistics experiments appears to be feasible, particularly using light targets such as $^{12}C$ or $^{16}O$.

A comprehensive evaluation of work and simulation based assessment in otolaryngology training
Creators: name: Awad, Zaid
Publisher: name: Imperial College London
Year: 2014

description: Introduction: The otolaryngology curriculum requires trainees to show evidence of operative competence before completion of training. The General Medical Council recommended that structured assessment be used throughout training to monitor and guide trainee progression. Despite the reduction in operative exposure and the variation in trainee performance, a ‘one size fits all’ approach continues to be applied. The number of procedures performed remains the main indicator of competence. Objectives: To analyse the utilisation, reliability and validity of workplace-based assessments in otolaryngology training. To identify, develop and validate a series of simulation platforms suitable for incorporation into the otolaryngology curriculum. To develop a model of interchangeable workplace- and simulation-based assessment that reflects trainee’s trajectory, audit the delivery of training and set milestones for modular learning. Methods: A detailed review of the literature identified a list of procedure-specific assessment tools as well as simulators suitable to be used as assessment platforms. A simulation-integrated training programme was piloted and models were tested for feasibility, face, content and construct validity before being incorporated into the North London training programme. The outcomes of workplace- and simulation-based assessments of all core and specialty otolaryngology trainees were collated and analysed. Results: The outcomes of 6535 workplace-based assessments were analysed. The strengths and weaknesses of 4 different assessment tools are highlighted. Validated platforms utilising cadavers, animal tissue, synthetic material and virtual reality simulators were incorporated into the curriculum. 60 trainees and 40 consultants participated in the process and found it of great educational value. Conclusion: Assessment with structured feedback is integral to surgical training. Assessment using validated simulation modules can complement that undertaken in the workplace. The outcomes of structures assessments can be used to monitor and guide trainee trajectory at individual and regional level. The derived learning curves can shape and audit future otolaryngological training.

description: New V photoelectric observations of the eclipsing system YY CMi, obtained at La Silla, Chile, and Merate Observatory, Italy, are presented. New times of minima and ephemeris based on our observations are also given. The V light curve was analysed by using the WD code to derive the geometrical and physical parameters of the system. Since no spectroscopic mass ratio is available, the q-search method was applied to yield the preliminary range of the mass ratio in order to search for the final solution. First the unspotted solution was carried out by using the unperturbed parts of the light curve and applying the DC program of the WD code. The solution was performed by assuming contact (mode 3) and semi-detached (mode 4) configuration, since no classification of the system is possible from the shape of the light curve. The solution in mode 4 does not lead to an acceptable model, since the secondary was found to be slightly overcontact. Therefore the contact solution was finally adopted. Moreover the light curve peculiarities (Max II fainter than Max I and excess of light around the phase 0.32) were explained by assuming a cool and a hot spot on the surface of the secondary (cooler) component. The degree of contact is very small (f about 3%) and the thermal contactis poor (T1-T2) about 650 K. These results together with the high photometric mass ratio q about 0.89 indicate that YY CMi is very probably a system at the beginning or the end of the contact phase.

On Markovian approximation schemes of jump processes
Creators: name: Mina, Francesco
Publisher: name: Imperial College London
Year: 2014

description: The topic of this thesis is the study of approximation schemes of jump processes whose driving noise is a Levy process. In the first part of our work we study properties of the driving noise. We present a novel approximation method for the density of a Levy process. The scheme makes use of a continuous time Markov chain defined through a careful analysis of the generator. We identify the rate of convergence and carry out a detailed analysis of the error. We also analyse the case of multidimensional Levy processes in the form of subordinate Brownian motion. We provide a weak scheme to approximate the density that does not rely on discretising the Levy measure and results in better convergence rates. The second part of the thesis concerns the analysis of schemes for BSDEs driven by Brownian motion and a Poisson random measure. Such equations appear naturally in hedging problems, stochastic control and they provide a natural probabilistic approach to the solution of certain semi linear PIDEs. While the numerical approximation of the continuous case has been studied in the literature, there has been relatively little progress in the study of such equations with a discontinuous driver. We present a weak Monte Carlo scheme in this setting based on Picard iterations. We discuss its convergence and provide a numerical illustration.

Some topics in topological graph theory motivated by chemistry
Creators: name: Barthel, Senja Dominque
Publisher: name: Imperial College London
Year: 2015

description: Topological graph theory is a field of geometric topology. The mathematical objects of interest are embeddings of graphs in 3-space. The image is a so called spatial graphs. A spatial graph can be seen as a generalised knot. In addition to the resulting richer structure, questions about spatial graphs can also be motivated from other natural sciences. In particular, there are many applications to chemistry since molecules can be modelled as graphs embedded in R3. This text consists of two parts. Both cover pure mathematical problems which are motivated by questions from synthetic chemistry. The aim is to find materials with new chemical/physical properties. The structural richness of entangled, catenated and knotted structures has long been a target for synthetic chemistry. The first part investigates the behaviour of entanglements in spatial graphs that are not caused by knotted or linked subgraphs with respect to the surfaces the spatial graphs embed in. We show that all nontrivial embeddings of abstractly planar graphs on the torus contain either a nontrivial knot or a nonsplit link. It follows that ravels do not embed on the torus which was conjectured by Castle, Evans and Hyde in 2008. Our results provide general insight into properties of molecules that are synthesised on a torus. The second part predicts the topologically possible braided structures of 1-dimensional coordination polymers. Given the common way of synthesising via self-assembly, these coordination polymers can be modelled by pure braids with n rigidly congruent strands up to chirality. We discuss the properties and symmetries of 1-dimensional coordination polymers with up to five strands. This project is part of a collaboration with Prof D. M. Proserpio, Dr I. A. Baburin and Dr F. D.-H. Lau.

description: Active matter, as other types of self-organizing systems, relies on the take-up of energy that can be used for different actions, such as active motion or structure formation. Here we provide an agent-based framework to model these processes at different levels of organization, physical, biological and social, using the same dynamic approach. Driving variables describe the take-up, storage and conversion of energy, whereas driven variables describe the energy consuming activities. The stochastic dynamics of both types of variables follow a modified Langevin equation. Additional non-linear functions allow to encode system-specific hypotheses about the relation between driving and driven variables. To demonstrate the applicability of this framework, we recast a number of existing models of Brownian agents and Active Brownian Particles. Specifically, active motion, clustering and self-wiring of networks based on chemotactic interactions, online communication and polarization of opinions based on emotional influence are discussed. The framework allows to obtain critical parameters for active motion and the emergence of collective phenomena. This highlights the role of energy take-up and dissipation in obtaining different dynamic regimes.

description: The paper aims at building a conceptual framework on how user innovation concept may be employed for the idea of creating innovation network between universities and business. Such innovation network would serve different purposes that are currently qualified as barriers for innovation management in business organizations as lack of easy access to lead-user innovators; difficulties in building minimal viable products; problems in validating innovation in its pre-market phase, etc. On the other hand, such innovation network would also satisfy some identified problems in innovation management education like reducing the gap between theory and business; teaching students through real live projects, etc. The approach for designing the conceptual framework steps on the user innovation theory. A literature analysis on user innovation identifies the utility of utilizing users in innovation development. Based on these, a focus group with 15 innovation managers qualitatively validates whether the identified 26 user activities in innovation development from prior researches would be beneficial if students take the role of user innovators (educated user innovators). The conceptual framework is built as a result from the respondents’ answers by designing where students may participate in innovation development as user innovators and how beneficial it is expected to be that cooperation. The assessment aims also at define the best place where the proposed activities may take place within the innovation development process. The finding of the study may play the role of a roadmap for user utilization in innovation development.

description: It is well known that a spinning body moving in a fluid suffers a force orthogonal to its velocity and rotation axis --- it is called the Magnus effect. Recent simulations of spinning black holes and (indirect) theoretical predictions, suggest that a somewhat analogous effect may occur for purely gravitational phenomena. The magnitude and precise direction of this "gravitational Magnus effect" is still the subject of debate. Starting from the rigorous equations of motion for spinning bodies in General Relativity (Mathisson-Papapetrou equations), we show that indeed such an effect takes place and is a fundamental part of the spin-curvature force. The effect arises whenever there is a current of mass/energy, non-parallel to a body's spin. We compute the effect explicitly for some astrophysical systems of interest: a galactic dark matter halo, a black hole accretion disk, and the Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime. It is seen to lead to secular orbital precessions potentially observable by future astrometric experiments and gravitational-wave detectors. Finally, we consider also the reciprocal problem: the "force" exerted by the body on the surrounding matter, and show that (from this perspective) the effect is due to the body's gravitomagnetic field. We compute it rigorously, showing the matching with its reciprocal, and clarifying common misconceptions in the literature regarding the action-reaction law in post-Newtonian gravity.

description: We report on kinematic observations of Ha emission line from four late-type galaxies of Hickson Compact Group 16 (H16a,b,c and d) obtained with a scanning Fabry-Perot interferometer and samplings of 16 km/s and 1". The velocity fields show kinematic peculiarities for three of the four galaxies: H16b, c and d. Misalignments between the kinematic and photometric axes of gas and stellar components (H16b,c,d), double gas systems (H16c) and severe warping of the kinematic major axis (H16b and c) were some of the peculiarities detected. We conclude that major merger events have taken place in at least two of the galaxies group. H16c and d, based on their significant kinematic peculiarities, their double nuclei and high infrared luminosities. Their Ha gas content is strongly spatially concentred - H16d contains a peculiar bar-like structure confined to the inner $\sim$ 1 h^-1 kpc region. These observations are in agreement with predictions of simulations, namely that the gas flows towards the galaxy nucleus during mergers, forms bars and fuel the central activity. Galaxy H16b, and Sb galaxy, also presents some of the kinematic evidences for past accretion events. Its gas content, however, is very spare, limiting our ability to find other kinematic merging indicators, if they are present. We find that isolated mergers, i.e., they show an anormorphous morphology and no signs of tidal tails. Tidal arms and tails formed during the mergers may have been stripped by the group potential (Barnes & Hernquist 1992) ar alternatively they may have never been formed. Our observations suggest that HCG 16 may be a young compact group in formation throught the merging of close-by objects in a dense environment.

description: We model the broadband (optical/UV and X-ray) continuum spectrum of the "changing-look" active galactic nucleus (AGN) Mrk 1018 as it fades from Seyfert 1 to 1.9 in $\sim 8$ years. The brightest spectrum, with Eddington ratio $L/L_{\rm Edd}\sim 0.08$, has a typical type 1 AGN continuum, with a strong "soft X-ray excess" spanning between the UV and soft X-rays. The dimmest spectrum, at $L/L_{\rm Edd} \sim 0.006$, is very different in shape as well as luminosity, with the soft excess dropping by much more than the hard X-rays. The soft X-ray excess produces most of the ionizing photons, so its dramatic drop leads to the disappearance of the broad line region, driving the "changing-look" phenomena. This spectral hardening appears similar to the soft-to-hard state transition in black hole binaries at $L/L_{\rm Edd} \sim 0.02$, where the inner disc evaporates into an advection dominated accretion flow, while the overall drop in luminosity appears consistent with the Hydrogen ionization disc instability. Nonetheless, both processes happen much faster in Mrk 1018 than predicted by disc theory. We critically examine scaling from galactic binary systems, and show that a major difference is that radiation pressure should be much more important in AGNs, so that the sound speed is much faster than expected from the gas temperature. Including magnetic pressure to stabilize the disc shortens the timescales even further. We suggest that all changing-look AGNs are similarly associated with the state transition at $L/L_{\rm Edd} \sim$ a few percent.

Newspaper articles, internet blogs, and textbooks are just some examples of written works that use illustrated texts to communicate information. In order to facilitate and improve comprehension of illustrated texts, it is important to understand the underlying cognitive processes (Mayer, 2021b). This dissertation project aimed to specify the ongoing cognitive processes when processing illustrated texts. To this end, the research presented in this project focused on the Resonance-Integration-Validation model of text comprehension (RI-Val, O’Brien & Cook, 2016a, 2016b) in combination with the Cognitive Theory of Multimedia Learning (CTLM; Mayer 2021a, 2021b). The RI-Val model assumes that readers passively activate information stored in long-term memory that overlaps with the current content that is being read, integrate the activated and currently read content, and validate the newly formed linkages, that is, check them for consistency. The CTML does not yet consider these passive processes. The overarching research questions investigated in this dissertation were whether activation, integration, and validation processes apply to illustrated texts, and, if so, whether pictures might influence these processes. To answer these questions, three research packages (A-C), each consisting of three experiments, were conducted (total N = 2,496). All nine experiments used adapted versions of what is known as the contradiction paradigm (Albrecht & O’Brien, 1993). In this paradigm, reading times for a target and the following sentence (i.e., spillover sentence) are measured. It was varied whether the information presented beforehand was consistent or inconsistent with the target sentence and whether the previously mentioned consistent or inconsistent information was illustrated with a picture or not. Overall, the results show that activation, integration, and validation processes apply to illustrated text and that these processes occur across modalities (i.e., text and picture). Furthermore, a summary with meta-analytic measures showed that pictures when presented beforehand slightly accelerated the reading times of the target sentences. These findings broaden the scope of the RI-Val model and further specify the cognitive processes identified within the CTML, by showing that passive activation, integration, and validation processes apply to illustrated texts and that they occur across modalities (i.e., for information from both texts and pictures).

description: Due to the increase in volume, velocity, and variety of data under analysis, software development practices and teams are increasingly being incorporated into non-IT components of academic organizations undertaking translational or clinical research. In this rapidly developing field, efficient software to analyze -omics data lag behind the newest technologies.

At the UAB Center for Computational Genomics and Data Science (CCGDS) and in previous iterations of our team elsewhere, we developed innovating software to address a variety of needs within the genomic medicine space. We apply novel methods in the creation of tools for the analysis and interpretation of omic-based data for clinical diagnoses and research in human disease. For example, we developed commercial-grade tertiary analysis software that enabled analysts to interpret and report a whole-genome in hours. Several labs have adopted this software for analysis over previously-used commercial software. It surpassed tools from larger software companies despite being created by 3FTE core developers over two years.

Our approach relies on a high degree of integration across the wide spectrum of specialties within our team, including analysts, biomedical and data scientists, and software engineers. While subgroups exist within the team focused around specialties, all successful outcomes, including software releases and patient diagnoses, can be contributed to the tight integration points iteratively developed among teammates. Disciplined software engineers evolve applications with rapid turnaround to increase our flexibility to quickly satisfy evolving user requirements.

In addition to supporting efficiency, we find the subgroups of our team have incorporated advantageous aspects of each other’s distinctly different work cultures and lived experiences. Our results show efficiency and effectiveness through this synthesis. Significant effort is invested in collaborative activities to cultivate these connections as our team grows.

The various methods and tools that we use to develop a variety of deliverables including processes, protocols, algorithms, and software within the group will be detailed. Included are discussions of 1) tools and methods that support teamwork and efficiency across a team that is geographically distributed, such as Scrum, Slack, 2) methods and tools that develop a sense of team and cohesion including standups, 3) processes and methods used to develop group culture including a team charter and mission.

description: Significant properties are those aspects of a digital record that must be preserved over time in order for the Information Object to remain accessible and meaningful. This report examines the notion of significant properties as it applies to electronic mail, a common form of digital communication. It seeks to identify the significant properties of email that must be maintained by examining each of its constituent elements and analyzing their designated function. It goes on to examine strategies that may be utilized to maintain access to e-mail assets in the longterm. Finally, it outlines a set of experiments that were performed by the project team to identify and evaluate tools that may be utilized to convert significant properties from one form to another.

description: We study a cubic lattice gas model for nuclear matter where each lattice site can be either occupied, by one proton or one neutron, or unoccupied. A nearest-neighbor interaction of the form $ - \sum_{} J_{ij}τ_{zi} τ_{zj}$ is assumed. Our model is an isospin-1 Ising model, with ${τ_z}$ = (1,0,-1) representing respectively (proton, vacancy, neutron). A kinetic-energy term has been included in our model. Under the Bragg-Williams mean field approximation our model exhibits the existence of a dense phase (liquid-like) and a rare phase (gas-like). The nuclear-matter p-v isotherms given by our model are discussed.

description: Light field (LF) cameras provide perspective information of scenes by taking directional measurements of the focusing light rays. The raw outputs are usually dark with additive camera noise, which impedes subsequent processing and applications. We propose a novel LF denoising framework based on anisotropic parallax analysis (APA). Two convolutional neural networks are jointly designed for the task: first, the structural parallax synthesis network predicts the parallax details for the entire LF based on a set of anisotropic parallax features. These novel features can efficiently capture the high frequency perspective components of a LF from noisy observations. Second, the view-dependent detail compensation network restores non-Lambertian variation to each LF view by involving view-specific spatial energies. Extensive experiments show that the proposed APA LF denoiser provides a much better denoising performance than state-of-the-art methods in terms of visual quality and in preservation of parallax details.

description: We analyse synthetic galaxy spectra from the evolutionary models of Bruzual&Charlot and Fioc&Rocca-Volmerange using the method of Principal Component Analysis (PCA). We explore synthetic spectra with different ages, star formation histories and metalicities, and identify the Principal Components (PCs) of variance in the spectra due to these different model parameters. The PCA provides a more objective and informative alternative to diagnostics by individual spectral lines. We discuss how the PCs can be used to estimate the input model parameters and explore the impact of noise in this inverse problem. We also discuss how changing the sampling of the ages and other model parameters affects the resulting PCs. Our first two synthetic PCs agree with a similar analysis on observed spectra obtained by Kennicutt and the 2dF redshift survey. We conclude that with a good enough signal-to-noise (S/N>> 10) it is possible to derive age, star formation history and metallicity from observed galaxy spectra using PCA.

description: We investigate two key representative semiclassical approaches for propagating resonant energy transfer between a pair of electronic two-level systems (donor and acceptor) with coupled Maxwell-Liouville equations. On the one hand, when the electromagnetic (EM) field is treated classically and Coulomb interactions are treated quantum-mechanically, we find that a quantum-classical mismatch leads to a violation of causality, i.e., the acceptor can be excited before the retarded EM field arrives. On the other hand, if we invoke a classical intermolecular Coulomb operator, we find that the energy transfer in the near field loses quantitative accuracy compared with Förster theory, even though causality is strictly obeyed. Thus, our work raises a fundamental paradox when choosing a semiclassical electrodynamics algorithm. Namely, which is more important: Accurate short range interactions or long range causality? Apparently, one cannot have one's cake and eat it too.
