description: This paper proposes novel computational multiscale methods for linear second-order elliptic partial differential equations in nondivergence-form with heterogeneous coefficients satisfying a Cordes condition. The construction follows the methodology of localized orthogonal decomposition (LOD) and provides operator-adapted coarse spaces by solving localized cell problems on a fine scale in the spirit of numerical homogenization. The degrees of freedom of the coarse spaces are related to nonconforming and mixed finite element methods for homogeneous problems. The rigorous error analysis of one exemplary approach shows that the favorable properties of the LOD methodology known from divergence-form PDEs, i.e., its applicability and accuracy beyond scale separation and periodicity, remain valid for problems in nondivergence-form.

description: We study the combinatorics of modular flats of oriented matroids and the topological consequences for their Salvetti complexes. We show that the natural map to the localized Salvetti complex at a modular flat of corank one is what we call a poset quasi-fibration -- a notion derived from Quillen's fundamental Theorem B from algebraic $K$-theory. As a direct consequence, the Salvetti complex of an oriented matroid whose geometric lattice is supersolvable is a $K(π,1)$-space -- a generalization of the classical result for supersolvable hyperplane arrangements due to Falk, Randell and Terao. Furthermore, the fundamental group of the Salvetti complex of a supersolvable oriented matroid is an iterated semidirect product of finitely generated free groups -- analogous to the realizable case.
 Our main tools are discrete Morse theory, the shellability of certain subcomplexes of the covector complex of an oriented matroid, a nice combinatorial decomposition of poset fibers of the localization map, and an isomorphism of covector posets associated to modular elements.
 We provide a simple construction of supersolvable oriented matroids. This gives many non-realizable supersolvable oriented matroids and by our main result aspherical CW-complexes.

description: Hierarchical Bayesian Poisson regression models (HBPRMs) provide a flexible modeling approach of the relationship between predictors and count response variables. The applications of HBPRMs to large-scale datasets require efficient inference algorithms due to the high computational cost of inferring many model parameters based on random sampling. Although Markov Chain Monte Carlo (MCMC) algorithms have been widely used for Bayesian inference, sampling using this class of algorithms is time-consuming for applications with large-scale data and time-sensitive decision-making, partially due to the non-conjugacy of many models. To overcome this limitation, this research develops an approximate Gibbs sampler (AGS) to efficiently learn the HBPRMs while maintaining the inference accuracy. In the proposed sampler, the data likelihood is approximated with Gaussian distribution such that the conditional posterior of the coefficients has a closed-form solution. Numerical experiments using real and synthetic datasets with small and large counts demonstrate the superior performance of AGS in comparison to the state-of-the-art sampling algorithm, especially for large datasets.

PERCEPTION OF ACCENTS AND DIALECTS IN ADULTS AND INFANTS
Creators: name: BUTLER, JOSEPH PATRICK
Publisher: name: University of Plymouth
Year: 2010

description: This thesis has been undertaken with the purpose of investigating how adult speech processing systems are affected by. and how they cope with, the presence of different regional and foreign accents in speech, and to investigate the developmental origins of adult accent perception capabilities. Experiments 1 to 4 were designed to investigate the long term effects of exposure to different accents, and whether short term adaptation to an accent was possible, using a lexical decision task. The results demonstrated an effect of accent familiarity but no short term adaptation was evident. Experiments 5 to 7 investigated the short term effects of accents by looking at the length of activation of accent-related information in working memory by using a cross-modal matching task. The results found that selective accent related effects were reduced after a 1500 millisecond delay. Experiments 8 to 11 investigated infants' discrimination abilities for regional and foreign accents using a preferential looking habituation method, and found infants at 5 and 7 months could discriminate their own accent from another, unfamiliar regional accent, but could not discriminate two unfamiliar regional accents at 5 months or a foreign accent from their own at 7 months. Experiments 12 and 13 investigated how accents affected infants' word segmentation abilities with continuous speech at 10 months, and found that segmentation was impaired in the presence of regional and foreign accents. Using these results, the Accent Training Model (ATP) is proposed, which attempts to explain how accent related indexical information is processed in the speech processing system. The findings of the infant studies further our understanding of the effect of indexicat variation in early speech perception.

Twin-width of Planar Graphs; a Short Proof

description: The fascinating question of the maximum value of twin-width on planar graphs is nowadays not far from the final resolution; there is a lower bound of 7 coming from a construction by Král' and Lamaison [arXiv, September 2022], and an upper bound of 8 by Hliněný and Jedelský [arXiv, October 2022]. The upper bound (currently best) of 8, however, is rather complicated and involved. In the paper we give a short and simple self-contained proof that the twin-width of planar graphs is at most 11. We believe that this short proof can also shed more light on the topic of upper bound(s) on the twin-width of planar and beyond-planar graphs in general.

description: Autonomous soundscape augmentation systems typically use trained models to pick optimal maskers to effect a desired perceptual change. While acoustic information is paramount to such systems, contextual information, including participant demographics and the visual environment, also influences acoustic perception. Hence, we propose modular modifications to an existing attention-based deep neural network, to allow early, mid-level, and late feature fusion of participant-linked, visual, and acoustic features. Ablation studies on module configurations and corresponding fusion methods using the ARAUS dataset show that contextual features improve the model performance in a statistically significant manner on the normalized ISO Pleasantness, to a mean squared error of $0.1194\pm0.0012$ for the best-performing all-modality model, against $0.1217\pm0.0009$ for the audio-only model. Soundscape augmentation systems can thereby leverage multimodal inputs for improved performance. We also investigate the impact of individual participant-linked factors using trained models to illustrate improvements in model explainability.

INVESTIGATION AND SIMULATION OF HOT WATER USE AND PRODUCTION IN FARM DAIRIES
Creators: name: NORMAN, ALICE JANE
Publisher: name: University of Plymouth
Year: 1988

description: The dairy farming sector of European Agriculture is currently under considerable economic pressure so the aim of each farmer should be to produce saleable milk, at the lowest cost. One important area of concern is the expenditure on hot water for hygiene, as to be acceptable to the buyer the milk must have a low level of contaminants. Clean milk is produced from clean, healthy udders by means of equipment which is adequately and appropriately cleaned. To facilitate this hygienic milk production most dairies are eguipped with heaters to provide water at 40°C (for cleaning udders) and 80- 100°C (for plant cleaning). The practice of udder washing is a subjective process as it depends on the operator's judgement of a 'clean' udder and his view of necessity. In England and Wales there are two only accepted methods of plant cleaning, circulation cleaning and Acidified Boiling Water (A. B. W.). Prior to the. audit described it was expected that water and electricity consumption for plant cleaning would be predictable. To date there has been little information on the volume and temperature of water used on commercial dairy farms and the electricty consumed to produce this hot water. It is therefore difficult for farmers to make informed judgement on methods of reducing their electricity costs. Thirteen farms in South Devon have been monitored, to establish current practice: farmers were questioned about their water use; electricity and water consumption were metered for two years; and cleaning practices were observed. This survey has revealed that many non-standard cleaning methods are used on dairy farms, making the prediction of water and electricity consumption difficult. The management of equipment has been revealed as the most important aspect in determining the energy used. A computer model has been produced to simulate water heating in the farm dairy, which can be used to advise farmers as to the energy cost of their cleaning practices. This model has .been successfully used on several of the farms surveyed, on one farm its use resulted in energy savings in excess of 400 kWh per month.

AN EXPERT SYSTEMS APPROACH TO COLLISION AVOIDANCE
Creators: name: Blackwell, Grahame Kenneth
Publisher: name: University of Plymouth
Year: 1992

description: Any object or entity moving i n an open environment requires, together with certain navigational skills, the capacity to avoid collisions. Such ability presupposes: manoeuvrability; awareness of the nature of, and ability to detect, potential hazards; and innate intelligence to formulate, evaluate, and implement appropriate avoidance strategies. The maritime environment, and vessels moving within it, provide a classic illustration of the problems and principles of collision avoidance in two-dimensional space. Events in recent years, leading to loss of life, wastage of resources and pollution of the environment, have highlighted the limited success being achieved in this area. In most cases human error has been identified as the major factor; errors of judgement consequent on either a false sense of security or (more often) information overload - an excess of data from various sources, to be processed in limited time. This thesis describes the development of a shipboard expert system for marine collision avoidance. This system, to be operated in a microcomputer on the bridge, analyses all pertinent data on an encounter with another vessel and formulates an optimal strategy to deal with the situation. Detailed information on own-ships characteristics, including a mathematical manoeuvring model, is held in the knowledge base. Situational data relating to own-ship, potential hazards and any other relevant factors are to be input via on-board sensors , including ARPA (Automatic Radar Plotting Aid) ; keyboard input is an additional option . The user interface makes extensive use of an advanced WIMPS (Windows Icons-Mouse-Pointer System) environment; scrollable text and graphic s windows provide the main display; menus and dialogue boxes provide for input and control functions; all user facilities are mouse-operated. The system logic incorporates facilities for emergency manoeuvring, and t h e potential for extension to handle multi-ship encounters; direct input and consideration of electronic chart data on coastal features and shipping lanes has also been anticipated in the design. These issues are considered in some depth in the thesis and form the basis of two new research projects now in progress. The system has been validated for two-ship encounters i n the open sea, through expert appraisal of simulated manoeuvres and random simulation of large numbers of encounters; sea trial s on board a research vessel have shown it to be seaworthy and effective in practical operation.

description: For the realization of magnon-based current-free technologies, referred to as magnonics, all-optical control of magnons is an important technique for both fundamental research and practical applications. Magnon-polariton is a coupled state of magnon and photon in a magnetic medium, expected to exhibit magnon-like controllability and photon-like high-speed propagation. While recent studies have observed magnon-polaritons as modulation of incident terahertz waves, the influence of magnon-photon coupling on magnon propagation properties remains unexplored. This study aimed to observe the spatiotemporal dynamics of coherent magnon-polaritons through time-resolved imaging measurements. BiFeO$_3$ was selected as the sample due to its anticipated strong coupling between magnons and photons. The observed dynamics suggest that antiferromagnetic magnons can propagate over long distances, up to hundreds of micrometers, through strong coupling with photons. These results enhance our understanding of the optical control of magnonic systems, thereby paving the way for terahertz opto-magnonics.

Year: 2023
Subjects: subject: Numerical Analysis (math.NA)

description: This paper analyzes a regularization scheme of the Monge--Ampère equation by uniformly elliptic Hamilton--Jacobi--Bellman equations. The main tools are stability estimates in the $L^\infty$ norm from the theory of viscosity solutions which are independent of the regularization parameter $\varepsilon$. They allow for the uniform convergence of the solution $u_\varepsilon$ to the regularized problem towards the Alexandrov solution $u$ to the Monge--Ampère equation for any nonnegative $L^n$ right-hand side and continuous Dirichlet data. The main application are guaranteed a posteriori error bounds in the $L^\infty$ norm for continuously differentiable finite element approximations of $u$ or $u_\varepsilon$.

Here an experiment is presented to demonstrate the use of Rydberg atoms to solve (i.e., to program and obtain the solution of) the satisfiability (3-SAT) problem, which is the prototypical NP-complete problem allowing general programming of all NP problems. Boolean expressions of the 3-SAT problem are programmed with the blockade interactions of Rydberg atom graphs and their many-body ground states are experimentally obtained, to determine the satisfiabilities of the given 3-SAT problem instances quantum mechanically.

Occupational Commitment Under Conditions of Social Change: The Case of Professional Marine Engineering in Taiwan
Creators: name: CHIANG, YAN-NAN
Publisher: name: University of Plymouth
Year: 1995

description: The thesis is concerned with investigating the area of occupational commitment to marine engineering of students from various levels of higher education in maritime institutions. From a general description of socioeconomic change and its relationship to the seafaring profession, the study focuses on the case of Taiwan. A review of literature on commitment demonstrates that commitment may vary as the social-economy changes over time. As technology changes, ships' officers, more specifically marine engineers, are required by shipowners to be educated to degree level. The emphasis in this study is upon the commitment to the shipping industry of young engineering students at university. The theoretical model established takes individual intentions, willingness to study, and occupational commitment, as the dependent variables while students' demographic backgrounds, personal needs and values are taken as the independent variables. The theoretical model is tested with the aid of data from questionnaires administered to a sample of engineering students from various levels of academic institutions. The SPSS statistical package, including factor analysis and chi-squares, is employed on the data analysis. One result is that traditional Chinese cultural values, including "studying is superior to all other professions", and the current entrance examination system for Taiwanese universities, predominate in students "willingness to study", which in turn, affects the occupational commitment of engineering students. Another result shows that the "willingness to study" of students in seafaring-oriented departments is not related to their "occupational commitment". Marine Engineering at sea is not perceived as being able to satisfy the higher level needs of graduates. To overcome this disparity, the job characteristics of ships' engineer officers need redesigning to create a more challenging work context for graduate marine engineers. If, for whatever the reason, the job of the seagoing marine engineer cannot be redesigned to satisfy graduate engineers then the only alternative is to recruit non-graduate seagoing engineers from five year junior colleges.

Patina: a Method Oriented Design Environment for Parametric Analysis
Creators: name: Shurville, Simon
Publisher: name: University of Plymouth
Year: 1998

description: The central issue to be addressed in this thesis is the provision of support for design tasks that require problem formation and evaluation and some inventive adaptation of products and design strategies. Hitherto, computer tools have failed to support the full range of design tasks. In particular, they have been focused upon solving previously formulated design tasks in well-defined domains where little inventiveness with materials or design strategies is required (Green, 1992a). A solution is offered in the form of an analysis that yields a new class of system, called Method Oriented Design Environments (MODEs), which provide support for some of these more complicated design tasks. An implementation of such a system is presented in the fom1 of Patina: a MODE to support parametric analysis. It is argued that the lack of support for design tasks involving problem formulation, evaluation and inventiveness with components and strategies has partly been due to usage of an overly narrow view of the design process as a basis for system development on the part of developers of knowledge aided design. To provide a more complete orientation for these developers, and 'to expand the theory of knowledge aided design, an alternative model of design tasks is developed in the form of a 'design activity space' by transferring knowledge from the field of design research to that of knowledge aided design. A mapping is constructed between this new design activity space and Green's model space of tools for knowledge aided design (Green, 1992a). The mapping is first used to analyse the range of utility of some recent alternatives to traditional knowledge based systems for design. It is then used to single out a 'niche' of design tasks that are not supported by traditional systems or their more recent alternatives. The design tasks which lie in this niche awaiting support from computer tools share the following characteristics: ( 1) they encompass the activities of analysis, synthesis and evaluation, (2) they require an intermediate degree of innovation with the product, and (3) they require an intermediate degree of innovation in design strategy. The class of tools that are proposed to offer support to tasks in this niche are named MODEs because their defining characteristic is that the majority of their constituent knowledge is derived from a design method or strategy. Therefore the main item that is being represented to the user of a MODE is such a structured method rather than an evolving artefact. This is radically different from the traditional knowledge based tools, where the item being represented is an artefact in a particular domain, and from a recent proposal for systems that depict an unstructured process (Blessing, 1994). To demonstrate the feasibility of implementing a MODE, the implementation of a system called Patina, to support designers in applying the technique of parametric analysis, is reported.

description: Cardiac cine magnetic resonance imaging (MRI) is one of the important means to assess cardiac functions and vascular abnormalities. Mitigating artifacts arising during image reconstruction and accelerating cardiac cine MRI acquisition to obtain high-quality images is important. A novel end-to-end deep learning network is developed to improve cardiac cine MRI reconstruction. First, a U-Net is adopted to obtain the initial reconstructed images in k-space. Further to remove the motion artifacts, the motion-guided deformable alignment (MGDA) module with second-order bidirectional propagation is introduced to align the adjacent cine MRI frames by maximizing spatial-temporal information to alleviate motion artifacts. Finally, the multi-resolution fusion (MRF) module is designed to correct the blur and artifacts generated from alignment operation and obtain the last high-quality reconstructed cardiac images. At an 8$\times$ acceleration rate, the numerical measurements on the ACDC dataset are structural similarity index (SSIM) of 78.40%$\pm$.57%, peak signal-to-noise ratio (PSNR) of 30.46$\pm$1.22dB, and normalized mean squared error (NMSE) of 0.0468$\pm$0.0075. On the ACMRI dataset, the results are SSIM of 87.65%$\pm$4.20%, PSNR of 30.04$\pm$1.18dB, and NMSE of 0.0473$\pm$0.0072. The proposed method exhibits high-quality results with richer details and fewer artifacts for cardiac cine MRI reconstruction on different accelerations.

description: We consider a fermionic fluid in a non-equilibrium steady state where the fluctuation-dissipation theorem is not valid and fields conjugate to the hydrodynamic variables are explicitly required to determine response functions. We identify velocity-dependent forces in the kinetic equation that are equivalent to such fields. They lead to driving terms in the hydrodynamic equations and to corrections to the hydrodynamic initial conditions.

The Generation of Compound Nominals to Represent the Essence of Text The COMMIX System
Creators: name: Norris, Jennifer Vivien
Publisher: name: University of Plymouth
Year: 1998

description: This thesis concerns the COMMIX system, which automatically extracts information on what a text is about, and generates that information in the highly compacted form of compound nominal expressions. The expressions generated are complex and may include novel terms which do not appear themselves in the input text. From the practical point of view, the work is driven by the need for better representations of content: for representations which are shorter and more concise than would appear in an abstract, yet more informative and representative of the actual aboutness than commonly occurs in indexing expressions and key terms. This additional layer of representation is referred to in this work as pertaining to the essence of a particular text. From a theoretical standpoint, the thesis shows how the compound nominal as a construct can be successfully employed in these highly informative representations. It involves an exploration of the claim that there is sufficient semantic information contained within the standard dictionary glosses for individual words to enable the construction of useful and highly representative novel compound nominal expressions, without recourse to standard syntactic and statistical methods. It shows how a shallow semantic approach to content identification which is based on lexical overlap can produce some very encouraging results. The methodology employed, and described herein, is domain-independent, and does not require the specification of templates with which the input text must comply. In these two respects, the methodology developed in this work avoids two of the most common problems associated with information extraction. As regards the evaluation of this type of work, the thesis introduces and utilises the notion of percentage attainment value, which is used in conjunction with subjects' opinions about the degree to which the aboutness terms succeed in indicating the subject matter of the texts for which they were generated.

description: Omega Centauri, the largest known globular cluster in the Milky Way, is believed to be the remains of a dwarf galaxy's core. Giving its potential abundance of dark matter (DM), it is an attractive target for investigating the nature of this elusive substance in our local environment. Our study demonstrates that by observing Omega Centauri with the SKA for 1000 hours, we can detect synchrotron radio or Inverse Compton (IC) emissions from the DM annihilation products. It enables us to constrain the cross-section of DM annihilation down to $\sim {\rm 10^{-30}~cm^3~s^{-1}}$ for DM mass from several $\rm{GeV}$ to $\rm{100~GeV}$, which is much stronger compared with other observations. Additionally, we explore the axion, another well-motivated DM candidate, and provide stimulated decay calculations. It turns out that the sensitivity can reach $g_{\rm{aγγ}} \sim 10^{-10} ~\rm{GeV^{-1}}$ for $2\times 10^{-7} ~\rm{eV} < m_a < 2\times 10^{-4} ~\rm{eV}$.

Publisher: name: University of Plymouth

description: A programme of study was undertaken to assess the effect of pretreating raw soya bean and processed full fat soyabean meals with protease enzymes prior to use in liquid feed for grower and finisher pigs. A series of laboratory studies was undertaken to examine the efficacy of three microbial proteases (P2, P3 and P4) in partially hydrolysing soya protein and in reducing the levels of trypsin inhibitors in raw soyabean. Pretreatment consisted of steeping ground soyabean for 24 h at 20° C in the absence (control) or presence of 20 000 units gˉ¹ N of P2, P3 or P4. Pretreating raw soyabean (RSB) with P2, P3 and P4 significantly (P < 0.05) reduced trypsin inhibitor levels from 28.53 to 19.98, 17.17 and 18.35 (s.e.m.1.14) mg trypsin inhibited gˉ¹ soya respectively. Pretreating RSB, micronized (MIC) or autoclaved (AUT) soyabean meal with P2, P3 or P4 resulted in increases in soluble a.-amino nitrogen of 5.22, 7.08, and 6.58 (RSB), 5.11, 5.57 and 4.32 (MIC) and 3.56, 7.03 and 6.18 (s.e.d. 0.06) mg gˉ¹ soya respectively and in vitro digestibility of nitrogen of 7.6 %, 9.9 %and 6.4 % (RSB), 4.9 %, 8.3 % and 2.8 % (MIC) and 11 %, 8 % and 12.2 % (AUT) respectively compared with the appropriate controls. Feeding trials were conducted in which pretreated soya was added to a basal cereal diet. Pretreatment of RSB with P4 resulted in a significant (P < 0.05) increase in ADG of 0.08 kg pigˉ¹ dˉ¹ (s.e.d. 0.04) in grower pigs (33.5 ± 4 kg) over the 6 week duration of the trial but had no significant effect on FCR. Pretreatment of AUT with P4 did not significantly improve performance. In a feeding trial with grower/finisher pigs pretreatment of RSB with P3 resulted in significant (P < 0.05) improvements of 0.10 (s.e.d. 0.04) kg pigˉ¹ dˉ¹ in ADG and 0.476 (s.e.d. 0.19) in FCR. Pretreatment of MIC with P3 resulted in a significant reduction (P < 0.05) of 4 d (s.e.d. 1. 7) in the time taken for pigs to attain slaughter weight.

description: Pricing decisions of companies require an understanding of the causal effect of a price change on the demand. When real-life pricing experiments are infeasible, data-driven decision-making must be based on alternative data sources such as purchase history (sales data) and conjoint studies where a group of customers is asked to make imaginary purchases in an artificial setup. We present an approach for price optimization that combines population statistics, purchase history and conjoint data in a systematic way. We build on the recent advances in causal inference to identify and quantify the effect of price on the purchase probability at the customer level. The identification task is a transportability problem whose solution requires a parametric assumption on the differences between the conjoint study and real purchases. The causal effect is estimated using Bayesian methods that take into account the uncertainty of the data sources. The pricing decision is made by comparing the estimated posterior distributions of gross profit for different prices. The approach is demonstrated with simulated data resembling the features of real-world data.

ELECTRICITY USE IN THE FARM DAIRY
Creators: name: Bowes, Robert Christopher
Publisher: name: University of Plymouth
Year: 1989

description: Dairy farmers suffered substantially increased energy bills during the 1970's, at a time of herd expansion and modernisation of equipment to allow bulk milk refrigeration and storage on the farm. Little was known of the levels of electricity use in the dairy farming sector, but extrapolations had suggested a figure of 300 to over 400 kWh/cow/annum. Farmers were requesting quantitative estimates for the potential of conservation equipment, particularly plate heat exchangers and heat recovery units. An energy audit of dairy farms in South Devon is described. Over a period of two years, data were collected relating to energy use by each of the major components of a milking parlour and dairy, for a range of parlour sizes, levels of production and the ambient conditions. Analysis revealed the factors most influencing variations in energy use. An equation was developed to describe the energy use by a bulk milk tank, given the level of production and the ambient temperature. The bulk tank accounted for some 40% of the total energy used. The bulk tank has been studied in detail. The stages of heat transfer from the milk to the chilled water and the resulting effects upon the ice bank have been modelled. Laboratory investigations were carried out to determine some parameters empirically. The model's limits, sensitivity and validation are reported. Typical levels and ranges of energy use are suggested. A mean of approximately 250 kWh/cow/annum resulted from the audit, but 200 kWh/cow/annum was achieved by the most economical of farms without resort to conservation equipment, and this level is proposed as a target for the conscientious farmer. The factors affecting energy use in the farm dairy are identified as political, environmental, technical and managerial and these are discussed. The farmer's influence has to be directed mainly at the last of these categories. Investment in energy conservation equipment should not be considered until consumption is down to the proposed target level.
Sliced Optimal Transport on the Sphere

description: Sliced optimal transport reduces optimal transport on multi-dimensional domains to transport on the line. More precisely, sliced optimal transport is the concatenation of the well-known Radon transform and the cumulative density transform, which analytically yields the solutions of the reduced transport problems. Inspired by this concept, we propose two adaptions for optimal transport on the 2-sphere. Firstly, as counterpart to the Radon transform, we introduce the vertical slice transform, which integrates along all circles orthogonal to a given direction. Secondly, we introduce a semicircle transform, which integrates along all half great circles with an appropriate weight function. Both transforms are generalized to arbitrary measures on the sphere. While the vertical slice transform can be combined with optimal transport on the interval and leads to a sliced Wasserstein distance restricted to even probability measures, the semicircle transform is related to optimal transport on the circle and results in a different sliced Wasserstein distance for arbitrary probability measures. The applicability of both novel sliced optimal transport concepts on the sphere is demonstrated by proof-of-concept examples dealing with the interpolation and classification of spherical probability measures. The numerical implementation relies on the singular value decompositions of both transforms and fast Fourier techniques. For the inversion with respect to probability measures, we propose the minimization of an entropy-regularized Kullback--Leibler divergence, which can be numerically realized using a primal-dual proximal splitting algorithm.

MATHEMATICAL MODELLING OF THE DYNAMIC RESPONSE, IN SIX DEGREES OF FREEDOM, OF SMALL VESSELS IN A SEAWAY
Creators: name: Wallis, Barbara Diana
Publisher: name: University of Plymouth
Year: 1997

description: This thesis treats the motion of a small vessel described in six degrees of freedom. There are three are translation equations of motion and the other three are equations of angular motion. The aim is to develop a model with a sound mathematical base and use experimentation to find forces to aid the completion of the model, with the intention of use in an auto pilot, by the following means: 1) By solving the equations of motion for large movements, with given sea and wind conditions and also with given control forces and moments. 2) Deduce the forces and moments being applied from the sea etc., from the motion of the vessel. Thus to enable the auto pilot to deduce the required additional forces and the forces and moments applied by the water and wind and the control devices, such as the propeller and rudder. These two aims are achieved by analysing the transformation of axes using the standard Euler equations. However, as Euler's angles are ordered and therefore cannot cope with large angles which are present in the motion of a small vessel, another set of angles relating to axes and planes have been deduced. These are then rotated and the set of three measured angles are found in terms of the Euler angles. This is the main pan of original work in the thesis. The rest of the thesis is then based upon these set of measured angles and a general case mathematical model is deduced using them. This is proceeded by a functional analysis of the vessel's motion, environment and control action's. After that the general case model is theoretically validated by analysing the work done by ARJM Lloyd and showing how his work is a specific case of the general case. Experimental work performed on a small vessel is then used in the building of a mathematical model for the specific case of a small vessel, using a set of measured angles.

description: The present investigation was focused on the variations in rainwater infiltration experienced by soils of Gamboa zone (Panama Canal Watershed) during various seasons of the year, employing a time-lapse analysis of electrical resistivity tomography (ERT). In 2009, a total of 3 geoelectrical tests were undertaken during the dry, transition and rainy seasons across a profile 47 m in length, strategically distributed on site. The results obtained in this study showed strong variations in calculated resistivity between these seasons, taking the dry season as a reference with decreases and increases of percent difference of resistivity between -20% and -100%, and between 50% and 100%, respectively. These decreases, when displayed through a sequence of time-lapse images, reveal a superficial extension of the water content variations along the entire profile, as well as strong inversion artifacts showing false increases of calculated electrical resistivity. Decreases are the product of the rainfall increase obtained in this type of tropical environment; permanent conductive anomalies in 3 tests are associated with the streams close to the study site. The results of this work were compared with a simulation resulting from a series of bi-dimensional models applied to the 3 studies evaluated: dry, transition and rainy seasons.
