description: This study provides information about current farm data ownership practices, perceptions among producersâ€™ regarding the value of farm data, their willingness to pay for access to farm data, and the degree to which farmland leases specify ownership of farm data. Results indicate farmers are not generally willing to pay higher premiums to acquire historical farming data on rented farmland and operator-landlords are not generally interested in charging their tenants for farm data. This is likely driven by the rarity of farm data use agreements in farmland lease contracts since only 6% of renters report having a lease that clearly specified farm data ownership. However, farmers who rent a large portion of the land they operate express a higher willingness-to-pay, which may reflect their exposure to information asymmetries in farmland markets. Farmers largely believe that farm data collected on rented farmland is the legal property of the operator collecting the data, although farmers who rent land out to other operators are less inclined to agree that tenant-farmers own the data. As farm data collection continues to grow, data sharing agreements between landowners and tenants may become more popular.

description: We show that adding a vacuum expectation value to a gauge field left over from a dimensional reduction of three-dimensional pure supersymmetric Yang-Mills theory generates mass terms for the fundamental fields in the two-dimensional theory while supersymmetry stays intact. This is similar to the adjoint mass term that is generated by a Chern-Simons term in this theory. We study the spectrum of the two-dimensional theory as a function of the vacuum expectation value and of the Chern-Simons coupling. Apart from some symmetry issues a straightforward picture arises. We show that at least one massless state exists if the Chern-Simons coupling vanishes. The numerical spectrum separates into (almost) massless and very heavy states as the Chern-Simons coupling grows. We present evidence that the gap survives the continuum limit. We display structure functions and other properties of some of the bound states.

description: Farm managers must continuously manage risk in their farm business if they are to remain competitive and successful in their farm business operations. Although various risk management strategies can be adopted to reduce the uncertainties farmers face, the choice of a risk management strategy is influenced by the unique characteristics of the farm or the farm manager. Therefore, assuming a relationship between a particular risk and the strategy to be adopted may not necessarily be valid across heterogeneous decision makers. Using data from a 2017 survey, the risk management practices of grain and oilseed farmers in Saskatchewan is examined using a count-based approach of best-worst scaling and latent class cluster analysis. The results indicate there is considerable diversity among strategies producers perceive important.

description: The aim of this paper is to show that the invariant measure for a class of one dimensional chaotic maps, $T(x)$, is an extended solution of the Schröder functional equation, $q(T(x))=λq(x)$, induced by them. Hence, we give an unified treatment of a collection of exactly solved examples worked out in the current literature. In particular, we show that these examples belongs to a class of functions introduced by Mira, (see text). Moreover, as a new example, we compute the invariant densities for a class of rational maps having the Weierstrass $\wp$ functions as an invariant one. Also, we study the relation between that equation and the well known Frobenius-Perron and Koopman's operators.

description: Chiral superconductivity exhibits the formation of novel electron pairs that breaks the time-reversal symmetry and has been actively studied in various quantum materials in recent years. However, despite its potential to provide definitive information, effects of disorder in the crystal structure on the chiral superconductivity has not yet been clarified, and therefore the investigation using a solid-solution system is desirable. We report muon-spin-relaxation (muSR) results of layered pnictide BaPtAs_1-x_Sb_x_ with a honeycomb network composed of Pt and (As, Sb). We observed an increase of the zero-field muon-spin relaxation rate in the superconducting (SC) state at the Sb end of x=1.0, suggesting the occurrence of spontaneous magnetic field due to the time-reversal symmetry breaking in the SC state. On the other hand, spontaneous magnetic field was almost and completely suppressed for the As-Sb mixed samples of x=0.9 and 0.2, respectively, suggesting that the time-reversal symmetry breaking SC state in x=1.0 is sensitive to disorder. The magnetic penetration depth estimated from transverse-field muSR measurements at x=1.0 and 0.2 behaved like weak-coupling s-wave superconductivity. These seemingly incompatible zero-field and transverse-field muSR results of BaPtAs_1-x_Sb_x_ with x=1.0 could be understood in terms of chiral d-wave superconductivity with point nodes on the three-dimensional Fermi surface.

description: Backgrounding is the period between calf weaning and feedlot placement. There is no predetermined period for how long calves of specific weight classes should be backgrounded. The primary objective of this study was to establish which backgrounding period is the most economical and risk efficient for various weight groups of weaned Bonsmara calves in the Free State province of South Africa. A trial was conducted to establish performance data for four backgrounding treatments for four weaning weight groups. The performance data obtained from the trial were incorporated into an economic simulation model to determine the economic gross margins. Economic gross margins include the opportunity cost of the backgrounding pasture as the pasture rent. Gross margins for weekly cycles in 2020 were calculated. Furthermore, the gross margins were integrated into a stochastic efficiency with respect to a function (SERF) analysis to rank the strategies based on their risk efficiency. The findings indicated that no backgrounding should be conducted; instead, animals should be placed on the feedlot immediately. Economic gross margins and risk efficiency decreased as the backgrounding periods increased. However, when excluding the opportunity cost of land and simply calculating the accounting gross margins, the recommendations differ. Longer backgrounding periods are then more profitable and risk efficient, with the immediate feedlotting strategies being the least preferable. The conclusion is thus that the backgrounding pastures are too valuable to conduct backgrounding.

The dark sector consists of SU(2) dark gauge fields, two triplet dark Higgs fields, and two dark fermion doublets (dark matter candidates in this model). The dark sector interacts with the SM sector through kinetic and mass mixing operators. The model explains both PAMELA and Fermi LAT data very well and also satisfies constraints from both the DM relic density and Standard Model precision observables. The phenomenology of the model at the LHC is also explored.

description: Cholangiocarcinoma (CCA) is one of the most common hepatic and biliary malignancies. The overall five-year survival rate for cholangiocarcinoma is less than 15%. miR-28-5p has been reported to participate the development of various human cancer types. But whether miR-28-5p is associated with the clinical course of CCA patients has not been clarified. Herein, we observed that miR-28-5p was reduced in CCA tissues and predicts the poor prognosis of CCA patients. Treatment with the demethylating agent 5-aza-2’-deoxycytidine (5-AZA) restored miR-28-5p expression in CCA cell lines. Furthermore, up-regulated miR-28-5p inhibited CCA cells growth and metastasis. Mechanistically, miR-28-5p suppressed CCA cells growth and metastasis via directly targeting CD44 molecular. Specific CD44 special siRNA abrogated the discrepancy of the proliferation and metastasis capacity between miR-28-5p-overexpression CCA cells and their control cells, which further confirmed that CD44 was required in miR-28-5p-inhibited CCA cell growth and metastasis.

description: The primary purpose of this study was to measure brand loyalty in the agribusiness environment by applying a validated model that measures brand loyalty. Brand loyalty measurement in the agribusiness environment is based on an existing brand loyalty model originally developed for consumer products. The model was adapted and applied to the agribusiness environment and then used to measure the brand loyalty of farmers in the North-West Province (a corn-producing region) of South Africa. The twelve brand loyalty antecedents in the model are Customer satisfaction; Switching costs; Brand trust; Repeat purchase; Involvement; Perceived value; Commitment; Relationship proneness; Brand affect, Brand relevance, Brand performance, and Culture. Data were collected from 100 corn farmers in the region. The results concluded that the antecedents of brand loyalty are reliable, valid, and important to measure agribusiness brand loyalty. Therefore, the model can be used as a managerial tool to measure and manage agribusiness brand loyalty and improve its competitiveness. The study, thus, contributes to the strategic management of agribusinesses in the strategic management thereof.

description: Tile drain systems have been used for many years in agriculture; however, their popularity has increased over recent years. At the same time, questions around the costs and environmental impacts of these systems have increased. These concerns have left many operations and individuals questioning if the systems benefits outweigh itâ€™s costs. This paper presents a Life Cycle Costs (LCC) and Life Cycle Anaylsis (LCA) for implementing a new tile drain system into a traditional row crop operation. The results found that the use of four-inch single wall correcated pipe was the best piping for both economic and envirormental impacts. The model presented here, is the first model present an LCC and LCA for a tile drain system, and will provide the needed baseline to compare differnet system designs and materials for implementing a tile drain system.

Year: 2009
Subjects: subject: Plasma Physics (physics.plasm-ph)

description: We investigate the effects of collective modes on the temperature relaxation rates in fully coupled electron-ion systems. Firstly, the well-understood limit of weakly coupled plasmas is considered and the coupled mode formula within the random phase approximation is derived starting from the Lenard-Balescu kinetic equation. We show how the frequency integration can be performed by standard methods without applying additional approximations. Due to the well-defined approximation scheme, the results can serve as a benchmark for more approximate theories and numerical simulations in this limit. The coupled mode electron-ion transfer rates show a considerable reduction compared to the Fermi-Golden Rule approach for certain parameters and very small changes for other systems. We demonstrate how these coupled mode effects are connected to the occurrence of ion acoustic modes and under which conditions they occur. Interestingly, coupled mode effects can also occur for plasmas with very high electron temperatures; a regime, where the Landau-Spitzer approach is believed to give accurate results. Finally, we extend the approach to systems with strongly coupled ions by applying static local field corrections. This extension can substantially increase the coupled mode effects.

description: Massive black holes are key ingredients of the assembly and evolution of cosmic structures. Pulsar Timing Arrays (PTAs) currently provide the only means to observe gravitational radiation from massive black hole binary systems with masses >10^7 solar masses. The whole cosmic population produces a signal consisting of two components: (i) a stochastic background resulting from the incoherent superposition of radiation from the all the sources, and (ii) a handful of individually resolvable signals that raise above the background level and are produced by sources sufficiently close and/or massive. Considering a wide range of massive black hole binary assembly scenarios, we investigate both the level and shape of the background and the statistics of resolvable sources. We predict a characteristic background amplitude in the interval h_c(f = 10^-8 Hz)~5*10^-16 - 5*10^-15, within the detection range of the complete Parkes PTA. We also quantify the capability of PTAs of measuring the parameters of individual sources, focusing on monochromatic signals produced by binaries in circular orbit. We investigate how the results depend on the number and distribution of pulsars in the array, by computing the variance-covariance matrix of the parameter measurements. For plausible Square Kilometre Array (SKA) observations (100 pulsars uniformly distributed in the sky), and assuming a coherent signal-to-noise ratio of 10, the sky position of massive black hole binaries can be located within a ~40deg^2 error box, opening promising prospects for detecting a putative electromagnetic counterpart to the gravitational wave emission. The planned SKA, can plausibly observe these unique systems, although the number of detections is likely to be small. (Abridged)

description: We investigate the possibility that the large orbital eccentricity of the transiting Neptune-mass planet Gliese 436b is maintained in the face of tidal dissipation by a second planet in the system. We find that the currently observed configuration can be understood if Gliese 436b and a putative companion have evolved to a quasi-stationary fixed point in which the planets' orbital apses are co-linear and in which secular variations in the orbital eccentricities of the two planets have been almost entirely damped out. We adopt an octopole-order secular theory based on a Legendre expansion in the semi-major axis ratio to delineate well-defined regions of (P_c, M_c, e_c) space that can be occupied by a perturbing companion. We incorporate the evolutionary effect of tidal dissipation into our secular model of the system, and solve the resulting initial value problems for a large sample of the allowed configurations. We then polish the stationary configurations derived from secular theory with full numerical integrations. We present our results in the form of candidate companion planets to Gliese 436b. For these candidates, radial velocity half-amplitudes, K_c, are of order 3 m/s, and the maximum amplitude of orbit-to-orbit transit timing variations are of order Delta t=1 s to Delta t=5s. For the particular example case of a perturber with orbital period, P_c=40 d, mass, M_c=8.5 M_Earth, and eccentricity, e_c=0.58, we confirm our semi-analytic calculations with a full numerical 3-body integration of the orbital decay that includes tidal damping and spin evolution. Additionally, we discuss the possibility of many-perturber stationary configurations, utilizing modified Laplace-Lagrange secular theory.

description: Red supergiants are a short-lived stage in the evolution of moderately massive stars (10-25Mo), and as such their location in the H-R diagram provides an exacting test of stellar evolutionary models. Since massive star evolution is strongly affected by the amount of mass-loss a star suffers, and since the mass-loss rates depend upon metallicity, it is highly desirable to study the physical properties of these stars in galaxies of various metallicities. Here we identify a sample of red supergiants in M31 (the most metal-rich of the Local Group galaxies) and derive their physical properties by fitting MARCS atmosphere models to moderate resolution optical spectroscopy, and from V-K photometry.

description: Despite previous research evaluating the cost of grain harvesting operations and combines, there are still major gaps in the literature around the uncertainty of machine prices. Couple this with the recent price increases of new machines that have pushed operations to purchase used equipment. Which has led to the need for evaluating the various precision agriculture technologies and how they impact a combines value. The study proposed will aim to fill the holes in previous studies by predicting combine values across multiple makes and models. Unlike the previous studies, this work will evaluate the impact from various factors such as add-ons centered around precision agriculture in order to better predict the true value of the machine. In order to accomplish this task, the study will combine a hedonic model with an auction dataset from a national machinery sales company.

description: Velocity oscillations "measured" simultaneously at the photosphere and the chromosphere -from time series of spectropolarimetric data in the 10830 A region- of different solar magnetic features allow us to study the properties of wave propagation as a function of the magnetic flux of the structure (i.e. two different-sized sunspots, a tiny pore and a facular region). While photospheric oscillations have similar characteristics everywhere, oscillations measured at chromospheric heights show different amplitudes, frequencies and stages of shock development depending on the observed magnetic feature. The analysis of the power and the phase spectra, together with simple theoretical modeling, lead to a series of results concerning wave propagation within the range of heights of this study. We find that, while the atmospheric cut-off frequency and the propagation properties of the different oscillating modes depend on the magnetic feature, in all the cases the power that reaches the high chromosphere above the atmospheric cut-off comes directly from the photosphere by means of linear vertical wave propagation rather than from non-linear interaction of modes.

description: Concept of applying manure to a crop when needed can help with environmental issues of water quality in Iowa and the Upper Midwest in USA. Novel technologies have emerged which allow manure application on growing corn beyond V4 plant growth stage. Dribble Bar (Agrometer SDS 8000) allows manure application from planting up to a corn height of 1-meter (V9 growth stage) whereas 360 RAIN Robotic Irrigator allows diluted manure irrigation from planting to R5 corn growth stages. In addition to manure application during the growing season, both methods can reduce water stress on the corn plant during dry weather or drought conditions. This reduced stress can potentially result in an increase in corn grain yields. This paper compares the costs of manure application using Dribble Bar and 360 RAIN with the traditional method of fall or spring manure application with a drag-hose system when no crop is growing in the farm fields. A profitability analysis is then presented to show how the increased costs of manure application with these two specialized technologies can potentially be offset with increased income due to better corn grain yields. Such in-season manure application has potential to provide greater environmental benefit to the society with better nutrient management.

title: Legal medicine: acari trace evidence as forensic markers, when associated with crime scenes, clothed and concealed cadavers
Creators: name: Hani, Medjedline
Publisher: name: University of Reading
Year: 2019

description: The structure and nature of fabrics makes them one of the most valuable tools in forensic investigations of crime scenes. Fabrics are widely used by humans, and are commonly found in households, vehicles, offices and hospitals, in the form of clothing, or as part of the surrounding furniture. Because of their structure, they are able to retain associative traces from different origins. During a crime, the individuals involved are most often dressed, and come into contact with each other. The interaction between the participants in a crime and the crime scene and/or victim, leads to an exchange of traces, following Lockard’s exchange principle. The recognition, recovery and analysis of trace evidence - particularly Acari - from clothing, are fundamental to an accurate interpretation of clues provided by these traces. The retrieval of mite evidence from scenes of crimes has yet to be fully exploited by forensic investigators. This is principally due to the technical difficulty of recovering the mites, as well as an absence of experimental data and established protocols. To address this, here we aimed to assess the performance of commercially available forensic tapes at lifting mites from clothing. Amongst the tested tapes, we found that the J-Lar tapes performed best in a mite-recovery assay. In addition, we found that the negative-phototropic characteristics of common household mites could be exploited to drive greater numbers of mites onto the adhesive tapes and gels. Moreover, for best forensic practice, mites should be collected from the clothes as soon as possible, to diminish the time that has elapsed before lifting of the mites. We also investigated the effect of concealment of dead bodies using blankets, to understand the process of decomposition in relation to the possible preservation of mite traces from before death. The associative traces can be exploited as markers of crime scene location and as indicators of movements of cadavers after death. Mites found on a decomposing body may be useful in the estimations of time elapsed since death. Adequate knowledge of the mites biology such as habitats, lifecycle and populations dynamics, are beneficial to the assessment of time of colonisation by these mites or their carrier arthropods. Mites have proven their ability as associative markers in a forensic case study due to their environmental specificity, as a result of their sensitivity to subtle environmental changes. Our findings will be useful to forensic investigators with an interest in the use of trace evidence of acarological origin to draw inference.

description: Production agriculture is a cyclical business, the primary driver often being prices. During times of low prices and profitability, capital asset values often moderate or even decrease below trends, thus providing opportunities. The question posed in this research is what financial characteristics appear to be associated with those farms that do well during cyclical lows. That is, where are these farms significantly different coming out of a cyclical high that may be associated with their ability to do well during the cyclical low and thus potentially take advantage of opportunities? Data from 178 Wisconsin dairy farms from 2014 to 2018 were used. The year 2014 was the last of a cyclical high in profitability and 2018 was the last year of a cyclical low. The farms were split into two groups, high and low profit farms, by their Return on Assets at the end of 2018. Financial characteristics were then compared for the same two groups at the conclusion of 2014. Significant differences resulted for costs of production per sales unit, operating profit margin ratio, production, and herd size. The level of debt and working capital was not significantly different, but there was evidence of differing uses of debt.

description: This paper uses a linear-programming resource allocation model combined with sequencing and machinery selection to optimize the practices and machinery utilization of a Kentucky grain farm. After establishing a base model, further models were developed to evaluate the adoption of cover crops into a traditional row crop system. This was accomplished through maximizing returns over selected costs at various acreage adoption levels. Additionally, a decision tool was developed to assess the costs related to cover crop adoption. The results show a $30 per acre cost to adopt 1000 acres of cover crops when no benefits were considered.

description: Long-term trend in the closure of abattoir businesses has reduced â€œprivate killâ€ provision across the UK, leading to longer and more complex livestock journeys - jeopardising animal welfare, and threatening the viability of the locally-finished and -slaughtered red meat supply chain. This â€œproof of conceptâ€ study uses farmer and abattoir survey data, GIS software and Monte Carlo simulations to estimate the impacts of possible further closures of private kill abattoirs on the robustness of the private kill network. In August 2020, we estimate 18% of the UK was further than 45kms from a private kill abattoir, while 21% was serviced by one, 14% by two and 47% by three or more abattoirs. We estimate the robustness of the private kill network by calculating the size of these areas in turn should 9% or 18% of the existing private kill abattoirs stop operating. In both scenarios the area further than 45km from a private kill service, and with one and two providers increased, while the area with three or more providers decreased. The discussion considers additional information needed to allow this methodology a become a useful tool for supporting the private kill network by providing support to strategically located abattoir businesses within the overarching network of private kill businesses.

title: Essays on sentiment: an analysis of the commercial real estate market
Creators: name: Heinig, Steffen
Publisher: name: University of Reading

description: This thesis deals with the extraction, construction and analysis of commercial real estate (CRE) sentiment within Europe and the U.K. especially. The three empirical studies in this thesis may contribute to our understanding of the discipline. As I establish in the literature review, the analysis of commercial real estate sentiment still offers a lot of potential for further research. Since real estate markets are subject to sentiment swings, scholars and market participants should consider them in their market analysis. The first study establishes the need for sentiment consideration within the European real estate market. In order to justify the research of sentiment analysis, I have used different indirect and direct sentiment proxies and applied them in yield models for 80 different commercial property (sub-)markets within Europe. The statistical modification of different sentiment proxies is needed since not all European property markets offer direct sentiment measures. The results suggest, that the consideration of sentiment in a yield model framework adds significant information. I found, that CRE markets, which are assumed to be more liquid and developed, show a larger exposure to property specific sentiment measures. Markets, which are assumed to be less developed (i.e. Eastern European markets) on the other hand, have a larger exposure to more general macroeconomic sentiment indicators. The second study introduces a new method, which can be used to extract sentiment from text documents. The primary motivation for the use of text documents and the application of Natural Language Processing (NLP) methods lies in the fact that these documents are published much faster than other sentiment proxies. This allows extracting a much more accurate market sentiment. The second study should be understood as an introductory chapter to the method and the field of NLP. In total four different wordlists (AFINN, BING, NRC and TM) are used to extract the sentiment form various market reports for the CRE market in U.K. The study reveals that sentiment extracted from those documents, can be used to improve autocorrelated models. The last study uses those findings and applies different supervised learning methods. While the second study has produced sufficient results, the underlying text corpus of market reports has shown a series of insufficiencies. I have therefore, used a large dataset of more than 120,000 news articles, all concerning the British CRE market. Findings suggest, that the main issue of supervised learning algorithms is the appropriate classification of the different entities. I offer two approaches in order to construct robust sentiment indicators.

description: We present magnetic-torque experiments on the organic superconductor k-(BEDT-TTF)2Cu(NCS)2 for magnetic fields applied parallel to the 2D superconducting layers. The experiments show a crossover from a second-order to a first-order transition when the upper critical field reaches 21 T. Beyond this field, which we interpret as the Pauli limit for superconductivity, the upper critical field line shows a pro-nounced upturn and a phase transition line separates the superconducting state into a low- and a high-field phase. We interpret the data in the framework of a Fulde-Ferrell-Larkin-Ovchinnikov state.

Year: 2022

description: The main aim of the Critical Making project is to foster criticality in making and at the same time support the responsibility of the global maker movement and local makers and makerspaces by co-creating tailored RRI principles and practices for makers in collaboration with the Critical Making project team and practitioners. The Critical Making evaluation framework introduced in this document is an essential part in achieving these goals. It 1) outlines the general RRI and SDG goals of the project as well as specific goals for the three case action work packages focusing on gender, youth and openness in making, 2) introduces the co-evaluation approach which enables the consortium members to follow the impacts of case activities and to learn from the feedback throughout the case actions and 3) presents the evaluation process and measures for each of the case actions and 4) outlines how the evaluation framework is used and elaborated during the project to guarantee the responsibility of the project itself and to achieve the goals of the project.
title: Authenticity, performance and the construction of self: a journey through the terrestrial and digital landscapes of men's tailored dress
Creators: name: Bluteau, Joshua Max
Publisher: name: University of St Andrews
Year: 2018

description: This thesis explores high-end and bespoke menswear, tailoring and fashion, asking the question - why do some men choose to spend large sums of money to have clothes made for them? Using tailors and high-end menswear as a lens, this thesis unpacks how men construct their notion of self in the digital and terrestrial worlds through the clothes that they wear and the identities they perform. Based on twelve months’ terrestrial fieldwork in London and twenty-four months’ concurrent digital fieldwork with Instagram, this thesis examines notions of dress, performance and the individual across a multi-dimensional fieldsite set within a blended digital and terrestrial landscape. The fieldwork comprised visiting and interviewing tailors, and observing inside their workshops and at their fashion shows. In addition, the analyst-as-client built relationships with tailors, and constructed a digital self within Instagram through the publication of self-portraits and images of clothing. This thesis is presented in four chapters, flanked by an Introduction and Conclusion. These chapters move from an exploration of terrestrial research in the first two, to an analysis of digital research in the latter two. Five major motifs emerge in this thesis: the importance of the anthropology of clothing and adornment within western society; the nature of the individual in a digitised world; the difficulty in conducting western-centric fieldwork without an element of digital analysis; a methodological restructuring of digital anthropology; and the idea that a digital self can acquire agency. This thesis employs a pioneering blended methodology which brings together the fields of digital anthropology, visual anthropology and material culture to question how selves are constructed in a rapidly changing and increasingly digitised modernity. In conclusion, the thesis argues that individuals construct multiple digital selves and a sense of identity (around the notion of ‘authentic individualism’) that is illusory.

description: Physio-adaptive systems define a class of information systems that refer to an innovative mode where system interaction is reached by monitoring, analyzing, and responding to hidden psy-chophysiological user activity in real-time. However, despite a strong interest of scholars and practitioners in physio-adaptive systems, there exists a lack of a structured and systematic form in which physio-adaptive systems research can be classified. Against this backdrop, this article showcases the current state-of-the-art of physio-adaptive systems research along three different stages, namely (1) collection of physiological data, (2) state determination, as well as (3) system adaptation. Analyzing 44 articles during the years 1994 - 2019, our main contribution resides in the synopsis of physio-adaptive systems literature along these stages. For instance, we illus-trate that there exist three categories for adaptive responses: state display (20% of the analyzed studies), assistance offering (18%), and challenge adaptation (61%). On the grounds of our review, we propose seven promising avenues, which will support scholars in their endeavors on how to pursue with future research in the field of physio-adaptive systems.
title: Finite element methods as geometric structure preserving algorithms
Creators: name: Jackaman, James Iain
Publisher: name: University of Reading
Year: 2019

description: Here we investigate finite element techniques aimed at preserving the underlying geometric structures for various problems, and, in doing so, develop new geometric structure preserving methods. We initially focus on systems of Hamiltonian ODEs, examining the place of existing methods as geometric numerical integrators. We then develop a new geometrical finite element method for Hamiltonian ODEs with a view to generalise it to be the temporal discretisation of a space-time adaptive finite element method. We go on to investigate how well finite element methods can preserve the structure of Hamiltonian PDEs, which are a large class of physically relevant PDEs possessing a conserved physical invariant, the Hamiltonian functional, which often physically represents the energy of the problem. Examples of this kind of problem include, but are not limited to, oceanographical models of wave propagation such as KdV type equations and the nonlinear Schr¨odinger equations, and the semi-geostrophic equations for atmospheric modelling. We construct a general methodology for the design of finite element schemes for such problems and go on to develop multiple schemes in this framework for not only Hamiltonian PDEs but also systems of Hamiltonian PDEs. Within the study of finite element methods for Hamiltonian PDEs we prove both a priori and a posteriori error bounds, in addition to examining the role of spatial adaptivity for our schemes.
