▼ Renewable energy sources, e.g. solar energy and wind energy, have gained popularity as an alternative means of energy production as they do not reinforce global warming. In addition, more and more electrical appliances (e.g. electric vehicles, induction cookers, and heat pumps) are used as a substitute for appliances that need non-renewable energy sources. This increase in the use of renewable energy resources pushes the electricity grid to its limits due to new induced load peaks. The grid is not designed for these developments and as a result, asset deterioration, higher transport losses, and outages are expected to occur. The most straightforward solution for the distributed system operator, i.e. the operating manager of the distribution network, is to expand the grid. However, grid expansion is a costly operation and there are additional promising methods to decrease grid load peaks, e.g. by using different charging strategies for electric vehicles. The conventional charging strategy for electric vehicles is uncontrolled charging. With uncontrolled charging, the charging of the electric vehicle immediately commences once a connection with the charging pole is established. The smart charging strategy, however, is able to delay the charging moment to a more optimal time instant in view of, e.g. variable electricity prices. The vehicle-to-home (V2H) charging strategy is similar to smart charging, but in addition, the V2H strategy allows the electric vehicle to discharge electricity to power a nearby residential home. This research aims to compare smart charging and V2H charging on their economical effects for their users. The charging strategies are implemented using two control algorithms: a rule-based controller and a
model predictive control (MPC) algorithm. The rule-based controller is implemented due to its simplicity and the MPC algorithm is used for its ability to take into account predictions of system related variables, e.g. household loads. The MPC algorithm is implemented with two different forecasts namely, perfect information, i.e. uncertain variables are forecasted perfectly, and certainty equivalent, i.e. uncertain variables are predicted using a persistence forecast
model. The persistence forecast
model assumes that the future values of an uncertain variable remain equal to the latest measurements, e.g. the solar generation of tomorrow is expected to be equal to that of today. The control problem is non-linear as an electric vehicle behaves differently depending on its status, e.g. driving or charging. The control problem is therefore reformulated into a
mixed logical dynamical framework such that it can be solved efficiently using
mixed integer linear programming. An extensive comparison in performance for a microgrid case study is done using real data of solar generation, electric vehicles, and household loads for simulation. The results show that the V2H charging strategy can outperform smart charging by reducing both the peak loads and the electricity costs. However, the V2H strategy only gives a…

▼ Traditional electric power systems with large centralized base load power plants have a limited ability to react rapidly to the high supply variability associated with the increasing deployment of variable and intermittent renewable energy sources (RESs). Furthermore, with current power distribution networks primarily designed for unidirectional power flow, the introduction of reverse power flows by renewable feed-in strategies has been shown to negatively impact grid stability, security and system protection. For residential grid-connected microgrids (MGs) wishing to increase their renewable generation, these issues along with economic considerations often highlight that optimal operation can only be achieved through an increased self-consumption of locally generated renewable energy. Recently, researchers have highlighted that these issues can be addressed by the application of demand side management (DSM). Broadly speaking, these DSM strategies can be considered as programs which attempt to modify flexible user demands in order to achieve objectives such as reduced energy costs or increased RES utilization. To achieve these optimal energy management goals, this thesis focuses its efforts on the application of hybrid economic model predictive control (EMPC) strategies for the DSM of small to medium sized grid-connected residential MGs, containing both local photovoltaic (PV) generation capabilities and thermal energy storage (TES) devices. In particular, the investigation exploits thermal energy storage properties of switched domestic electric water heaters (DEWHs) to optimally schedule energy demand for the minimization of MG operating costs. By considering the time varying electricity tariffs, it is shown that the implementation of EMPC is able to simultaneously target reduced electricity costs while also encouraging the self-consumption of local PV generation. Finally, to address the unavoidable presence of uncertainty in domestic hot water (DHW) user demand, the thesis additionally explores the use of stochastic and robust variants of EMPC. By explicitly considering uncertainty, these control frameworks are able to provide more robust system operation. Specifically, the work implements min-max and stochastic scenario-based frameworks, which were shown to drastically reduce the violation of user comfort constraints when compared with their deterministic counterparts.

▼ Real-time optimisation of gas pipelines in transient conditions is considered to be a challenging problem. Many pipeline systems are, however, only mildly non-linear. It is shown, that even the shutdown event of a compressor station can be described using a linear model. A dynamic, receding horizon optimisation problem is defined, where the free response prediction of the pipeline is obtained from a pipeline simulator and the optimal values of the decision variables are obtained solving a Quadratic Programming (QP) problem set up by using linear models, linearised constraints and quadratic approximations of the cost function, which is the energy consumption of the compressor stations (CSs). The problem is extended with discrete decision variables, the shutdown/start-up commands of CSs. A Mixed Logical Dynamical (MLD) system is defined, but the resulting Mixed Integer QP problem is shown to be very high-dimensional. Instead, a series of QP problems, each containing linear constraints modelling the shut down state of CSs, results in an optimisation problem with considerably smaller dimension. The receding horizon optimisation is tested in a simulation environment and comparison with data from the Finnish natural gas pipeline shows that 5 to 8 % savings in compressor energy consumption can be achieved using optimisation. A new idea, maximisation of energy consumption, is used to calculate maximal energy savings potential of the pipeline. A new result is that step response models used in conjunction with MLD systems do not produce the same model change behaviour than state space models.

▼ This thesis is a discussion and continuation of a project started by John Etchemendy with his criticism of Tarski's account of
logical consequence. To this end the two central concepts of the thesis are those of an interpretational and representational
model-theoretic account of
logical consequence, respectively.
The first chapter introduces Etchemendy's criticism of Tarski's account of
logical consequence, a criticism which turns essentially on an interpretation of Tarski according to which his proposed account gives rise to a purely interpretational
model-theoretic account of
logical consequence. Consequently there must be a representational aspect to our
model-theoretic definition of
logical consequence.
The second chapter introduces Etchemendy's notion of
logical consequence: that of being truth preserving in virtue of the semantics of the involved terms. While this notion is representational, we argue that Etchemendy's notion of a categorematic treatment of terms reintroduces an interpretational aspect back into the
model theory. The chapter investigates the resulting notion, compares it to other notions in the literature, and presents certain results that can be proved, under certain conditions, about this notion in relation to the notion of being truth preserving in virtue of the semantics of all terms.
Chapter three of the thesis is concerned with the question of how a standard
model, seen as a domain and an interpretation function, manages to capture the different notions of
model-theoretic consequence. As we explain, this question is most pressing when we want our models to both represent and interpret, and we will present a theory which allows us to see the models as both representing non-actual possibilities as well as provide interpretations for the terms.
The fourth chapter applies the lessons of the preceeding chapters to argue that Kripke Semantics can be seen as capturing the notion of being truth preserving in all possibilities under all interpretations of the non-
logical terminology in the case where our language is augmented with an operator, ⃞, to represent
logical necessity. We will argue this point by contrasting it with, though not necessarily disagreeing with, claims made by various authors to the effect that Kripke Semantics is not the appropriate semantics when our language contains an operator for
logical necessity.

▼ Buckman Laboratories (Pty) Ltd. (hereafter referred to as Buckman Laboratories) is an international, privately owned, specialty chemical manufacturer. The company's marketing strategy is based on customer intimacy and knowledge sharing and currently segments its markets (pulp and paper, water, leather and mining) by means of customer categorization based on industry potential sales. The Buckman brand is synonymous with the heavy industries (Sasol, ArcelorMittal, Mondi, Sappi, Eskom). For the company to grow and increase its profitability, Buckman Laboratories has to identify and select innovative brand drivers to stay competitive in the heavy industry market segment as well as identify other market segments to compete profitably in.
In this study the Logical brand management model was specifically applied in terms of the customer perspective. Brand and cost drivers were identified from the company's and customers' perspective to identify opportunities in the current market segments (pulp and paper, water and leather). Metrics utilized were traditional gap analysis as well as the Opportunity Algorithm from Ulwick. Of importance was the consistent alignment of the model with Buckman Laboratories' strategy.
The model includes continuous improvement, on-time delivery, product innovation, knowledge sharing, and providing a holistic product/service offering as brand drivers that will ensure innovative growth of the Buckman Laboratories brand.
The conclusion is that the Logical brand management model as developed by Marc Logman may be successfully utilized to identify brand drivers to grow the Buckman Laboratories brand innovatively in future.

▼ Recent research concerning measurements of agreement between different methods or different raters have received wide attention. The concordance correlation coefficient (CCC) has been used to assess agreement between two raters or two measuring methods while the measurements are taken on the same continuous scale. However, the circumstances of repeated measurements may arise, e.g. longitudinal studies in clinical trials or bioassay data with sub-samples. The random variables are not independent nor identically distributed in that kind of situation. To appropriately account for the covariance between measurements, we have fitted three-level linear
mixed-effect models with random intercepts at two levels. The
model parameters are estimated using an expectation-maximization [E-M] like approach by iterating between the Empirical Bayes [EB] estimates of the random effects and maximum marginal likelihood estimates of the fixed and covariance parameters. For comparing agreement between two raters, we utilize two-level and three-level models to estimate CCC and observe that three-level models fit better for the dataset we collected in GAIT study. In order to handle missing data, we did the analysis with missing values by using
mixed-effects
model,
model imputation, multiple imputation and pattern
mixed model. We have achieved at consistent results among all the methods handling missingness in the dataset. The proposed
model also gives us the opportunities to evaluate agreement after adjusting for the other covariates. We also use an approach to get the generalized confidence interval of CCC for further statistical inference. Our approach represents a first attempt in evaluating CCC for data with multiple level variations.

▼ This work proposes a comprehensive querying database system based on an enhanced entity relationship (EER)
model. The DBMS is fully operational and performs all queries that are illustrated in the paper. This work is also applicable for the general ER
model proposed by Chen. So far, the ER
model is mainly used by database designers as a conceptual
model during the database design phase. An ER schema is usually mapped into a representation in the
logical model of the targeted database. As an analogy, the ER schema represents a program, written in a higher level language that is compiled into a lower level machine-executable equivalent. Semantics like the relationships among entities or the cardinality ratio constraints may no longer be available at the
logical model level. Queries are then written against the
logical model, which generates a discrepancy between the view of the database designer and the view of the database user. This work bridges this gap by introducing an EER-algebra and a high-level query language called ERSQL. The algebra is heavily based on the general ER-algebra proposed by Parent and Spaccapietra. To provide a semantic foundation for ERSQL we introduce a canonical translation algorithm that maps an ERSQL query into an EER-algebra expression. In recent years, in NoSQL data stores the functional primitives are greatly simplified for performance and scalability reasons. Our ERDBMS goes in the opposite direction: We use CISC (complex instruction set) operators but implement them efficiently in main-memory data storage.

▼ Demand for learning, design and decision making is higher than ever before. Autonomous
vehicles need to learn how to ride safely by recognizing pedestrians, traffic signs, and other cars.
Companies and consumers need to identify possible changes in the environment and adapt their
strategies relatively fast to stay competitive. The complexity of biological systems necessitates
incorporation of the biological knowledge with mathematical models to find effective treatments
for many chronic fatal diseases. This dissertation addresses some of the critical issues concerning
estimation, identification and learning of complex
dynamical systems observed through noisy data.
Nonlinear state-space models are a popular class of time series models with numerous applications
in fields such as cyber-physical systems, economics, biology and more. However, the
applicability of the existing techniques for inference of large systems or systems with big data sets,
two common scenarios in many real-world applications, becomes impossible. We have developed
a multi-fidelity Bayesian optimization algorithm for the inference of general nonlinear state-space
models (MFBO-SSM), which enables simultaneous sequential selection of parameters and approximators.
The accuracy and speed of the algorithm are demonstrated by numerical experiments
using synthetic gene expression data from a gene regulatory network
model and real data from the
VIX stock price index.
Along with estimation and identification, control of
dynamical systems has been on the center
of attention is many years. A Markov Decision Processes (MDPs) is a rich framework for
modeling the
dynamical systems in varieties of fields. The optimal control of MDP with known
dynamics and finite state and action spaces is achievable using the Dynamic programming (DP)
framework. However, in complex applications, there is often uncertainty about the system dynamics.
In addition, many practical problems have large or continuous state and action spaces which
hinders the simple application of DP. Reinforcement learning is a powerful technique widely used
for adaptive control of MDPs with unknown dynamics. Existing RL techniques developed for
MDPs with unknown dynamics rely on data that is acquired via interaction with the system or via
simulation. While this is feasible in areas such as robotics or speech recognition, in other applications
such as biology, manufacturing, cyber-physical systems, and marketing, there is either a lack
of reliable simulators or inaccessibility to the real system due to practical limitations, including
cost, ethical, and physical considerations. We have developed Bayesian decision making framework
for control of MDPs with unknown dynamics and large, possibly continuous, state, action,
and parameter spaces in data-poor environments. The effectiveness of the proposed framework
is demonstrated using a simple
dynamical system
model with continuous state and action spaces,
as well as a more complex
model for a metastatic melanoma gene regulatory network observed
through noisy…

▼ Homomorphic encryption is a form of encryption that allows computations to be carried out on ciphertext and generate an encrypted result which, when decrypted, matches the result of operations performed on the plaintexts. The feature of homomorphic encryption is used in modern communication system architectures and cryptosystems. In view of the previous works, most of homomorphic encryptions support additive or multiplicative homomorphism. There is few homomorphic encryption schemes tailored for
logical operations. In this paper, we propose a homomorphic encryption scheme that supports
logical operations. Additionally, our proposed scheme can be applied to 2-DNF and k-CNF. Furthermore, the proposed scheme achieves provable security under the subgroup decision assumption.

▼ In the era of the knowledge economy, companies whether to have the talent is the key to maintain their competitiveness and have the competitive advantages. Therefore, this study aims to find personalized talent management strategies by analyzing the company's transaction log. This study is based on data analysis, different from traditional human resources management strategies, to find out personal conditions of each talent and then give them different management strategies.
In this study, 623,863 transaction logs were collected from 2009 to 2016, and then used descriptive statistics to overview the talent development of the company, drew the growth curve of each talent , and then used data to establish a forecast
model to predict each talentâs retention rate and the expected revenue contribution in the next year.
According to the results of this study, the
model AUC is 84%, so the company can predict each talentâs retention rate, and if he/she stay he/she will bring how much revenue contribution. Based on the result, this study proposed a talent value matrix to help enterprises to manage different types of talent, coupled with the growth curve can do a more comprehensive talent development strategy. This study used data analysis to optimize the traditional human resources managementâs "training, development and retention" strategies and the personalized talent management can effectively assist enterprises to know each talentâs condition, maintain and create its competitiveness.

▼ Sentences in a formal language are true or false in a
given structure, or
model. A theory of truthmakers aims to provide
an account of \why sentences are true or false. This thesis studies
a theory of
model-relative truthmakers developed by Neil Tennant in
a series of recent works. One of the key facts about this theory is
that for any
model M there exists an M-relative truthmaker for a
sentence phi if and only if phi is true in M in the usual Tarskian
sense. After arithmetizing Tennant's theory of truthmakers, I show
that the weak theory RCA
0 suffices to prove this equivalence
between Tarskian truth and the existence of a truthmaker.I turn
next to notions of
logical consequence. The standard Tarskian
definition of
logical consequence requires that truth be preserved
from the premises to the conclusion. In the truthmaker-theoretic
setting, we can generalize this to require that ways of being true
be preserved from the premises to the conclusion. This in turn can
be understood to say that phi is a consequence of Delta if there is
a way to transform any truthmakers for the members of Delta into a
truthmaker for phi. Tennant had proposed a series of reduction
procedures analogous to proof-theoretic normalization that were
meant to accomplish this truthmaker-transformation. I show that
Tennant's procedure is flawed, failing to transform a truthmaker
for B into a truthmaker for "if A then (A and B)". I offer a
solution to this problem by defining a slightly more complicated
procedure for transforming truthmakers of the premises of an
argument into a truthmaker for the conclusion. I prove this
solution to be adequate in the sense that the resulting conception
of
logical consequence is coextensive with the standard Tarskian
definition, provided the premise set is consistent.

▼ We investigate several questions regarding the proposition that physical body size and one's image of their own body type affect the ability to make accurate judgements of distances. Data collected include subjects' guesses of distances of four cones set 10, 15, 20, and 25 meters away and the weight, BMI, and self-perception of body image for each of 67 subjects. Interest lies in determining the covariates that are most important in explaining one's ability to accurately judge distances and whether weight or BMI is the better explainer among the physical body size predictors. We utilize linear
mixed models to account for correlation among each subjects' own distance guesses and to allow for flexible modeling of
subject-specific effects. Flexibility is further promoted through use of
model averaging techniques to account for
model selection uncertainty inherent in typical approaches in which an analyst selects only one
model from which inferences are made. A generalization of the coefficient of determination from ordinary linear models is made to the linear
mixed model setting (R²LMM) in order to provide an additional goodness measure for fixed effects and for individual fixed effects themselves. Baseline differences among subjects' ability to accurately judge distances are so vast that extracting the importance of the fixed effects becomes difficult. It is found that body size is a significant predictor of subjects' ability to accurately judge distances but body image is not at the 0.05 significance level. We recommend choosing weight over BMI as a predictor of guessing behavior based on information criteria,
model averaging, and the generalized R²LMM. Specifically, heavier individuals tend to guess more accurately.

▼ This work deals with the car sequencing (CS) problem, a combinatorial optimization problem for sequencing mixed-model assembly lines. The aim is to find a production sequence for different variants of a common base product, such that work overload of the respective line operators is avoided or minimized. The variants are distinguished by certain options (e.g., sun roof yes/no) and, therefore, require different processing times at the stations of the line. CS introduces a so-called sequencing rule H:N for each option, which restricts the occurrence of this option to at most H in any N consecutive variants. It seeks for a sequence that leads to no or a minimum number of sequencing rule violations. In this work, CS’ suitability for workload-oriented sequencing is analyzed. Therefore, its solution quality is compared in experiments to the related mixed-model sequencing problem. A new sequencing rule generation approach as well as a new lower bound for the problem are presented. Different exact and heuristic solution methods for CS are developed and their efficiency is shown in experiments. Furthermore, CS is adjusted and applied to a resequencing problem with pull-off tables.
Die vorliegende Arbeit beschäftigt sich mit dem Car Sequencing (CS) Problem, einem kombinatorischen Optimierungsproblem zur Reihenfolgeplanung bei Variantenfließfertigung. Ziel ist es für verschiedene Varianten eines Basisproduktes eine Produktionsreihenfolge zu finden, sodass Überlastungen der Fließbandarbeiter vermieden bzw. minimiert werden. Die Varianten unterscheiden sich hinsichtlich der Ausprägung bestimmter Optionen (z.B. Schiebedach ja/nein) und benötigen dementsprechend eine unterschiedliche Montagezeit an den einzelnen Stationen des Fließbandes. CS führt für jede Option eine sogenannte Reihenfolgeregel H:N ein, die das Auftreten der Option in N aufeinanderfolgenden Varianten auf maximal H beschränkt. Es wird eine Reihenfolge gesucht, die zu keiner bzw. minimaler Anzahl an Regelverletzungen führt. In dieser Arbeit wird untersucht inwieweit sich CS tatsächlich für die überlastungsorientierte Reihenfolgeplanung eignet. Hierzu wird in Experimenten seine Lösungsqualität mit dem verwandten Mixed-Model Sequencing Problem verglichen. Die Arbeit präsentiert einen neuen Ansatz zur Erstellung von Sequenzregeln für CS, sowie eine neue Methode zur Berechnung einer unteren Schranke für das Problem. Verschiedene exakte und heuristische Lösungsverfahren für CS werden entwickelt und deren Effizienz in Experimenten nachgewiesen. Darüberhinaus wird CS auf ein Resequencing Problem mit Pull-Off Tables anpasst and angewendet.

▼ Recent advances in multimedia research have generated a large collection of concept models, e.g., LSCOM and Mediamill 101, which have become accessible to other researchers. While most current research efforts still focus
on building new concepts from scratch, little effort has been made to construct new concepts upon the existing models already in the "warehouse". To address this issue, we have developed a new framework in this thesis, termed LEarning structured
model by probabilistic loGic Ontology (LEGO) to seamlessly integrate both the new target training examples and the existing
primitive concept models. LEGO treats the primitive concept models
as a Lego toy to potentially construct an unlimited vocabulary of new concepts. Specifically, LEGO first formulates the logic operations to be the Lego
connectors used to combine existing concept models hierarchically in probabilistic logic ontology trees. LEGO then simultaneously incorporates new target training information to efficiently disambiguate the underlying logic
tree and correct the error propagation. We present extensive experimental results on a large vehicle domain data set from ImageNet and demonstrate
significantly superior performance over existing state-of-the-art approaches which build new concept models from scratch.

▼ We investigate a proposal to address several outstanding shortcomings of the perturbative Standard
Model (SM) of particle physics, specifically a common,
dynamical origin for the number of fermion generations, the spectrum of fermion masses and for Charge-Parity (CP) violating processes. The appeal of this proposal is that these features are a manifestation of the non-perturbative sector of the SM, requiring no assumptions about new physics beyond presently attainable experimental limits. In this thesis we apply non-perturbative techniques, which have been
used to investigate
dynamical symmetry breakdown in other quantum field theories, to the U/(1) hypercharge sector of the SM, peculiar among chiral gauge theories in that the same gauge field mediates both interacting sectors. We consider two models, a toy 4-fermion
model containing explicit chiral symmetry-breaking terms (of an anomalous origin) and the quenched hypercharge gauge interaction, which complement each other. The key difference between this theory and studies of "conventional" breaking (such as in the gauged Nambu Jona Lasinio
model) is the realisation that here fermion pairing terms associated with
dynamical chiral symmetry breakdown are a necessary but not sufficient requirement for
dynamical mass generation, analogous to the pseudogap phenomenon observed in systems of strongly-correlated electrons. Understanding of how the mass, generations and CP-violation might arise are first investigated in the toy 4-fermion
model. It is shown that different scale-invariant 4-fermion operators are present for the three subspaces of the full theory enabling self-consistent introduction of three fermion generations. The second part of the thesis is concerned with
dynamical fermion mass generation in the quenched hypercharge interaction. In particular we follow the successful procedure developed for QED, developing a 1-loop renormalisable vertex ansatz for solution of the fermion self-energy Dyson-Schwinger equation. In the absence of
dynamical fermion-antifermion bound states it is found there exist two mass "gaps" corresponding to two types of condensate. These "gaps" cannot be interpreted as physical fermion mass. It is suggested that only after the incorporation of the composite scalars does the self-energy equation admit multiple (physical) solutions. An alternative possibility, that of a rearrangement of fermionic degrees of freedom analogous to spin-charge separation (SCS) in condensed matter physics, is also briefly outlined.

▼ Governing laws and equations, such as Newton's second law for classical mechanics and the Navier-Stokes equations thence derived, have been responsible throughout history for numerous scientific breakthroughs in the physical and engineering sciences. There are many systems of interest for which large quantities of measurement data have been collected, but the underlying governing equations remain unknown. While machine learning approaches such as sparse regression and deep neural networks have been successful at discovering governing laws and reduced models from data, many challenges still remain. In this work, we focus on the discovery of nonlinear
dynamical systems models from data. We present several methods based on the sparse identification of nonlinear dynamics (SINDy) algorithm. These approaches address a number of challenges that occur when dealing with scientific data sets, including unknown coordinates, multiscale dynamics, parametric dependencies, and outliers. Our methods focus on discovering parsimonious models, as parsimony is key for obtaining models that have physical interpretations and can generalize to predict previously unobserved behaviors.

▼ This thesis compares different techniques for applying reduced order modeling to PDE constrained optimization and develops a new method based on recent work by Dihlmann and Haasdonk.
Model reduction techniques have been used to significantly reduce computation time for solving PDEs. But naive application of
model reduction in the optimization context may lead to incorrect results. To overcome this, Dihlmann and Haasdonk recently proposed a method applicable to problems with a small number of optimization parameters. I develop an approach that extends this idea to accommodate problems with a larger number of optimization parameters and, under certain assumptions, satisfies an a posteriori error estimate. I show that the proposed scheme achieves an accurate approximation with as much as a 70 fold decrease in computation time compared to solving the full
model. I also show my method compares favorably with an approach proposed by Kunisch and Volkwein.

▼ This dissertation examines the effect of two types of system complexity, nonlinearity and heterogeneity, on oscillatory dynamics in networked systems. In particular, we focus on finding conditions for complete synchronization, where the dynamics of multiple systems are identical, phase locking, where the dynamics of multiple systems share critical features, and
mixed mode oscillations (MMOs), where the dynamics of a single system demonstrate periodic oscillations with peaks of markedly different sizes. A fascinating application of these conditions is to networks of
model neurons and the crucial role of synchronization in brain function.
We establish conditions for synchronization in networks of heterogeneous systems with nonlinear dynamics and diffusive coupling. We leverage a passivity-based Lyapunov approach to find a condition for complete synchronization in networks of identical nonlinear systems in terms of the network structure and the dynamics of individual systems. An application to networked
model neurons with biologically relevant parameter values demonstrates improvement over alternative methods. Cluster synchronization is an extension of complete synchronization where the network can be partitioned into distinct subgroups of systems that are synchronized. We find conditions for cluster synchronization in networks of non-identical systems with nonlinear dynamics and diffusive coupling using a passivity-based Lyapunov approach and a contraction based approach.
We examine a system of two
model neurons where the first neuron receives a constant external input and the second neuron receives input from the first through diffusive coupling. Large networks that are cluster synchronized can be represented by simpler systems; in particular, the dynamics of a network synchronized in two clusters can be represented by a system of two coupled
model neurons. We use techniques from
dynamical systems theory to characterize parameter regimes where each
model neuron is resting, firing, or sustaining MMOs. The system of two
model neurons and its extensions represent a foundation for investigating how network structure and external stimuli interact to influence the dynamics in networks of neurons.
Characterization of the conditions for when synchronization may arise in networks of heterogeneous nonlinear systems is a crucial step toward understanding complex networked systems.

▼ Matrix models are formulated to study the dynamics of the structured populations. We consider closed populations, that is, without migration, and populations with migration. The effects of specific patterns of migration, whether with constant or time-dependent terms, are explored within the context of how they manifest in model output, such as population size. Time functions, commonly known as relative sensitivities, are employed to rank the parameters of the models from most to least influential in the population size or abundance of individuals per group

▼ The study of the Hubbard model in three dimensions contains a variety of phases dependent upon the chosen parameters. This thesis shows that there is the indication of a zero temperature phase transition at a finite doping. The Hubbard model has been used to identify a similar quantum critical point in two dimensions. The presented results continue these investigations. The system demonstrates a strange metal phase at finite temperature which cannot be described in term of the conventional Fermi liquid. While there have been extensive studies over the past three decades for such materials in two dimensions, there are few numerical studies in three dimensions. This study strives to identify the existence of the strange metal beyond two dimensions. In this work we present numerical results based on the dynamical cluster approximation to demonstrate the existence of a strange metal phase in three dimensions.

▼ Generally, large-scale
dynamical systems pose tremendous computational difficulties when applied in numerical simulations. In order to overcome these challenges we use several
model reduction techniques. For stable linear models these techniques work very well and provide good approximations for the full
model. However, large-scale unstable systems arise in many applications. Many of the known
model reduction methods are not very robust, or in some cases, may not even work if we are dealing with unstable systems. When approximating an unstable sytem by a reduced order
model, accuracy is not the only concern. We also need to consider the structure of the reduced order
model. Often, it is important that the number of unstable poles in the reduced system is the same as the number of unstable poles in the original system. The Iterative Rational Krylov Algorithm (IRKA) is a robust
model reduction technique which is used to locally reduce stable linear
dynamical systems optimally in the mathcal{H}
2-norm. While we cannot guarantee that IRKA reduces an unstable
model optimally, there are no numerical obstacles to the reduction of an unstable
model via IRKA. In this thesis, we investigate IRKA's behavior when it is used to reduce unstable models. We also consider systems for which we cannot obtain a first order realization of the transfer function. We can use Realization-independent IRKA to obtain a reduced order
model which does not preserve the structure of the original
model. In this paper, we
implement a structure preserving algorithm for systems with nonlinear frequency dependency.

▼ Global reanalyses provide the most consistent atmospheric circulation datasets for many
dynamical processes that are not easily observed. Reanalysis products are, however, of limited value in hydrological applications due to the coarse spatial scales they are available at.
Dynamical downscaling of these products offers a means to convert them to finer spatial scales useful in resolving dominant atmospheric processes and thus leading to improved accuracy in the surface climate derived. In downscaling the climate of the recent past with a regional climate
model (RCM), lateral boundary conditions (LBCs) are created from an available reanalysis in order to simulate the observed climate. This allows the investigation of regional climate processes and quantification of the errors associated with the regional
model. Thus the global reanalysis being downscaled should provide the most accurate LBCs in order to produce the best downscaled simulations. Despite this, choice of reanalysis to perform such downscaling has mostly been left to convenience, a researchers familiarity or on performance of the reanalysis within the regional domain for variables such as near-surface air temperature and precipitation. These variables may only partially be relevant for downscaling as they do not directly reflect information contained in the LBCs fields which are the principal input to a RCM. A framework to evaluate reanalyses derived LBCs to choose the most accurate at the intended boundaries and time of an example domain over southern Africa is demonstrated. The robustness of the approach is demonstrated over a different domain in the same region. The two reanalyses with the best LBCs are subsequently downscaled over 31 years (1980-2010). It is revealed that although choice of LBCs has a bearing on simulations of a RCM, internal
model physics also plays some role in determining the simulated near-surface temperature and precipitation. The evaluations are extended to basin scale where the resultant near-surface temperature and precipitation are also found to be useful especially in studying sustained hydrological extremes over the data poor region. It is also revealed that simple bias correction of raw reanalyses temperature and relative humidity fields before downscaling gives
mixed results in terms of improving the simulation.

▼ The Arctic and sea ice cover play fundamental roles in the environment of the Earth system. Improved causal understanding of their changes is needed for meaningful predictions and planning. Among the linkages composing our understanding and predictions, hypothesized mechanisms and historical cases suggest that potentially long-lived, (sub-)synoptic coherent circulation features termed tropopause polar vortices (TPVs) can impact the evolution of Arctic sea ice on daily to seasonal time scales. Diagnostics and causal
dynamical experiments are developed to evaluate whether there are mechanisms sufficient for TPVs to significantly impact Arctic summer sea ice loss.
A TPV's place, structure, and history are intimately related to its dynamics and associated impacts. A restricted regional watershed segmentation and major correspondence overlap TPV tracking method more robustly defines tracked TPVs' spatial structure (through restricted regional watershed basins with variable shapes and intensities) and time evolution (through similarity overlap with mergers and splits) relative to previous methods. Tracking with a more restrictive definition of lifetime and more robust, variable size, individual cyclonic TPVs can exceed radii of 1000~km, amplitudes of 40~K, and lifetimes of 2 months, coincide with multi-day extreme sea ice loss, and contribute seasonal-scale geographic anomalies.
To represent the potential, integrated impacts of TPVs on Arctic sea ice, it is argued that a comprehensive
model should resolve TPVs and feedbacks with the larger polar circulation, consistently couple and realistically evolve sea ice, and be computationally tractable. Motivated by limitations in limited-area and coarser general circulation models to satisfy these requirements, the
Model for Predictions Across Scales non-hydrostatic atmospheric
dynamical core is embedded within the Community Atmospheric
Model of the Community Earth System
Model (CESM-CAM-MPAS). A global, Arctic-refined atmospheric configuration efficiently provides needed local resolution to TPVs with two-way feedbacks to the polar circulation. Coupling with an Earth system
model evolves sea ice through process-based exchanges. With
mixed historical and analog initial conditions intended to balance considerations of realism and consistency, summer simulations capture mean polar circulation anomalies and yield competitive September sea ice extent forecasts with skill for the sea ice edge. An effective, localized tendency-based modification strategy permits sensitivity experiments to quantify causal responses throughout the Earth system to input TPV perturbations.
Sensitivity experiments are conducted with directly modified TPV intensity within the coupled Earth system to causally explore and evaluate whether TPVs can have extreme sea ice impacts. Strong intensification of cyclonic TPVs in the Arctic can cause less summer sea ice loss. Multi-scale, thermodynamic, mechanical, and multi-component mechanisms contribute to differences in sea ice mass, momentum, and…

▼ Arctic ice extent serves as one of the best proxy indicators of climate change. The annual Arctic ice extent average has declined at an alarming and continual rate for the last 50 years. The Arctic ice is without a doubt becoming vulnerable and fragile in both thickness and resilience, and scientists around the world worry about witnessing an ice-free summer in the imminent future. Most climate scientists predict that the first ice-free Arctic summer will happen before or around 2050, including the researchers of the Intergovernmental Panel on Climate Change (IPCC). The majority of these forecasts are made with ocean-atmosphere general circulation models (GCMs), highly complex in their input and output, which often renders traditional mathematical analysis difficult. This thesis aims to develop a mathematically tractable and analyzable model of the Arctic sea ice extent using the structure of Budyko-type energy balance models (EBM) and a previous master's student Wen Xing's model, with the goal of making a deterministic prediction for the first ice-free Arctic summer. The new model, which will be called the Daily Budyko model, extends the original annual average Budyko-type EBM to the daily scale and recalibrates model parameters for the domain of the northern polar region. In addition, new model equations are constructed using the main idea of proportional growth in Xing's model. The Daily Budyko model predicts September of 2051 for the first ice-free Arctic summer, which is in line with the IPCC's forecast of around 2050.

▼ The main topic of this paper is to forecast the inflation of Taiwan. As a most common prediction
model, Error Correction
Model (ECM) uses data that must be processed at the same frequency. The omission of high-frequency variables for observation may lead to loss of information. Therefore, in this paper, the
Mixed Frequency Error Correction
Model (MF- ECM) presented by GoÌtz et al. (2014) is adopted along with
Mixed Data Sampling. Sampling at different frequencies can obtain information at the low-frequency and high-frequency as well as explore the short and long-term relationship between the non-stationary data. It not only has the advantages of cointegration and error correction, but also improves both the problem of the high-frequency data loss and the performance of predictability.
The period for data collection was from January 2006 to December 2016, with 132 pieces of the monthly data and 528 pieces of the weekly data, the main variables being the Wholesale Price Index (WPI), Consumer Price Index (CPI) and crude oil prices. The
Mixed Frequency Error Correction
Model is used to predict WPI and CPI, and whether MF-ECM is better than ECM in predictability is also explored. According to the assessment at the three indexes of power of prediction, the empirical result of the study shows that MF-ECM is better than ECM in predictability.

▼ Mixed linear regression is a high dimensional affine space clustering problem where the goal is to find the parameters of multiple affine spaces that best fit a collection of points. We introduce a convex 2nd order cone program (based on l1/fused lasso) which allows us to reformulate the
mixed linear regression as an Rd clustering problem. The convex program is parameter free and does not require prior knowledge of the number of clusters, which is more tractable while clustering in Rd. In the noiseless case, we prove that the convex program recovers the regression coefficients exactly under narrow technical conditions of well-separation and balance. We demonstrate numerical performance on BikeShare data and music tone perception data.

▼ La plupart des patients infectés par le VIH ont une charge virale qui peut être rendue indétectable par des combinaisons antirétrovirales hautement actives (cART); cependant, il existe des effets secondaires aux traitements. L'utilisation des modèles mécanistes dynamiques basés sur des équations différentielles ordinaires (ODE) a considérablement amélioré les connaissances de la dynamique HIV-système immunitaire et permet d'envisager une personnalisation du traitement. L'objectif de ces travaux de thèse est d'améliorer les techniques statistiques d'estimation de paramètres dans les modèles mécanistes dynamiques afin de proposer des stratégies de surveillance et d'optimisation des traitements. Après avoir introduit NIMROD un algorithme d'estimation bayésienne basé sur une maximisation de la vraisemblance pénalisée, nous montrons la puissance des approches mécanistes dynamiques pour l'évaluation des effets traitements par rapport aux méthodes descriptives d'analyse des trajectoires des biomarqueurs. Puis, nous définissons le « modèle à cellules cibles », un système ODE décrivant la dynamique du VIH et des CD4. Nous montrons qu'il possède de bonnes capacités prédictives. Nous proposons une preuve de concept de la possibilité de contrôler individuellement la dose de traitement. Cette stratégie adaptative réajuste la dose du patient en fonction de sa réaction à la dose précédente par une procédure bayésienne. Pour finir, nous introduisons la possibilité de l’'individualisation des changements de cART. Ce travail passe par la quantification in vivo d'effets de cART en utilisant des indicateurs d'activité antivirale in vitro. Nous discutons la validité des résultats et les étapes méthodologiques nécessaires pour l'intégration de ces méthodes dans les pratiques cliniques.
Most HIV-infected patients viral loads can be made undetectable by highly active combination of antiretroviral therapy (cART), but there are side effects of treatments. The use of dynamic mechanistic models based on ordinary differential equations (ODE) has greatly improved the knowledge of the dynamics of HIV and of the immune system and can be considered for personalization of treatment. The aim of these PhD works is to improve the statistical techniques for estimating parameters in dynamic mechanistic models so as to elaborate strategies for monitoring and optimizing treatments. We present an algorithm and program called NIMROD using Bayesian inference based on the maximization of the penalized likelihood. Then, we show the power of dynamic mechanistic approaches for the evaluation of treatment effects compared to methods based on the descriptive analysis of the biomarkers trajectories. Next, we build the “target cells model “, an ODE system of the dynamics between the HIV and CD4. We demonstrate it has good predictive capabilities. We build a proof of concept for drug dose individualization. It consists in tuning the dose of the patient based on his reaction to the previous doses using a Bayesian update procedure. Finally, we introduce the…
