▼ In the modern era there is an unprecedented ability to actuate via an increasingly cheaper array of actuators, and to sense through a growing, increasingly cheaper, array of sensors. The ability to sense in particular represents both the unique opportunity and the unique challenge of our time. It is an opportunity because through the acquired data, it is possible to glean insight into processes that are still too complex to be modeled correctly, and a challenge because the sheer volume of data generated is often overwhelming. Paradoxically, despite having the capability to collect vast stores of data, we still lack knowledge of how to best analyze and use this data. In fact, multiple review papers have demonstrated that published methods are too application specific and depend too strongly on the data set size to be deployed on the scale necessary to address the problem. Heated debates rage in the scientific literature on how to best reduce the data into meaningful features and how to apply this reduced data to solve real-world problems. This thesis proposes a novel approach to reducing the dimension of data into meaningful features that preserve the information of the data, but also enable the localization of a small, newly collected, set of data in a previously stored data set. The process of identifying a location within a stored data set is termed in-sequence localization and it is particularly important in applications such as vehicle localization, economic forecasting, energy generation mode selection, and stream health monitoring, where stored data can be used to infer the present and future state of a process. To enable the process of in-sequence localization, this thesis proposes to model the data using autoregressive models, such that a small number of model coefficients can be used to represent large subsets of data. Then using these autoregressive models, in-sequence localization is performed by comparing new data with the models and determining model feasibility. Emphasizing the fact that this method is to be used on practical data, the models are determined such that in-sequence localization is robust to the data collection noise typically observed in sensors. This thesis is developed around the application of vehicle localization. This motivating application arises from the need to augment position estimates of the Global Positioning System in the event of emergencies or signal occlusions. We return repeatedly to this application because of its intuitive nature when conveying concepts throughout the thesis. To demonstrate the broad applicability of the methods, data from the applications of economic forecasting, energy generation mode selection, stream health monitoring, and random data is used to demonstrate algorithms throughout the text.

O presente trabalho é referente ao estudo das indústrias líticas do sítio Brito, localizado na margem direita do rio Paranapanema, no Estado de São Paulo. Os materiais estudados estão associados a datações recuadas a transição Holoceno Inicial/Médio, entre, aproximadamente, 8.000 BP e 6.500 BP. O nosso primeiro objetivo concerne à caracterização tecnológica das indústrias líticas a partir de uma abordagem centrada no conceito de cadeia operatória visando reconstituir os processos técnicos e as estratégias de uso das matérias primas que geraram a variabilidade artefatual observada. O segundo objetivo trata da verificação, por meio da análise da distribuição vertical e horizontal dos vestígios, da integridade de solos de ocupação identificados durante a escavação. Propomos que as indústrias líticas mais antigas do sítio Brito estão distribuídas em um nível arqueológico caracterizado por um palimpsesto de ocupações.

The present dissertation refers to the study of the lithic assemblages from the Brito site, located at the right bank of the Paranapanema river, in the state of São Paulo. The materials that were studied are associated to dates that go back to the transition between the initial and the middle Holocene, approximately 8,000 to 6,500 BP. Our first objective concerns the technological characterization of the lithic assemblages from an approach based on the concept of operation sequence (chaîne opératoire), with the aim of reconstituting the technical processes and the strategies of usage of raw material that generated the observed artifact variability. The second objective was to verify, by means of analyzing the vertical and horizontal distribution of the lithic materials, the integrity of the occupational floors identified during the fieldwork. We suggest that the oldest lithic assemblages of the Brito site are distributed over an archeological level characterized by a palimpsest of occupations.

▼ Several computational biology and bioinformatics problems involve DNA sequence classification using supervised machine learning algorithms. The performance of these algorithms is largely dependent on the availability of labeled data and the approach used to represent DNA sequences as {\it feature vectors}. For many organisms, the labeled DNA data is scarce, while the unlabeled data is easily available. However, for a small number of well-studied model organisms, large amounts of labeled data are available. This calls for {\it domain adaptation} approaches, which can transfer knowledge from a {\it source} domain, for which labeled data is available, to a {\it target} domain, for which large amounts of unlabeled data are available. Intuitively, one approach to domain adaptation can be obtained by extracting and representing the features that the source domain and the target domain sequences share. \emph{Latent Dirichlet Allocation} (LDA) is an unsupervised dimensionality reduction technique that has been successfully used to generate features for sequence data such as text. In this work, we explore the use of LDA for generating predictive DNA sequence features, that can be used in both supervised and domain adaptation frameworks. More precisely, we propose two dimensionality reduction approaches, LDA Words (LDAW) and LDA Distribution (LDAD) for DNA sequences. LDA is a probabilistic model, which is generative in nature, and is used to model collections of discrete data such as document collections. For our problem, a sequence is considered to be a ``document" and k-mers obtained from a sequence are ``document words". We use LDA to model our sequence collection. Given the LDA model, each document can be represented as a distribution over topics (where a topic can be seen as a distribution over k-mers). In the LDAW method, we use the top k-mers in each topic as our features (i.e., k-mers with the highest probability); while in the LDAD method, we use the topic distribution to represent a document as a feature vector. We study LDA-based dimensionality reduction approaches for both supervised DNA sequence classification, as well as domain adaptation approaches. We apply the proposed approaches on the splice site predication problem, which is an important DNA sequence classification problem in the context of genome annotation. In the supervised learning framework, we study the effectiveness of LDAW and LDAD methods by comparing them with a traditional dimensionality reduction technique based on the information gain criterion. In the domain adaptation framework, we study the effect of increasing the evolutionary distances between the source and target organisms, and the effect of using different weights when combining labeled data from the source domain and with labeled data from the target domain. Experimental results show that LDA-based features can be successfully used to perform dimensionality reduction and domain adaptation for DNA sequence classification problems.

▼ Science and engineering problems frequently require solving a sequence of single linear systems or a sequence of dual linear systems. We develop algorithms that recycle Krylov subspaces and preconditioners from one system (or pair of systems) in the sequence to the next, leading to efficient solutions. Besides the benefit of only having to store few Lanczos vectors, using BiConjugate Gradients (BiCG) to solve dual linear systems may have application-specific advantages. For example, using BiCG to solve the dual linear systems arising in interpolatory model reduction provides a backward error formulation in the model reduction framework. Using BiCG to evaluate bilinear forms – for example, in the variational Monte Carlo (VMC) algorithm for electronic structure calculations – leads to a quadratic error bound. Since one of our focus areas is sequences of dual linear systems, we introduce recycling BiCG, a BiCG method that recycles two Krylov subspaces from one pair of dual linear systems to the next pair. The derivation of recycling BiCG also builds the foundation for developing recycling variants of other bi-Lanczos based methods like CGS, BiCGSTAB, BiCGSTAB2, BiCGSTAB(l), QMR, and TFQMR. We develop a generalized bi-Lanczos algorithm, where the two matrices of the bi-Lanczos procedure are not each other's conjugate transpose but satisfy this relation over the generated Krylov subspaces. This is sufficient for a short term recurrence. Next, we derive an augmented bi-Lanczos algorithm with recycling and show that this algorithm is a special case of generalized bi-Lanczos. The Petrov-Galerkin approximation that includes recycling in the iteration leads to modified two-term recurrences for the solution and residual updates. We generalize and extend the framework of our recycling BiCG to CGS, BiCGSTAB and BiCGSTAB2. We perform extensive numerical experiments and analyze the generated recycle space. We test all of our recycling algorithms on a discretized partial differential equation (PDE) of convection-diffusion type. This PDE problem provides well-known test cases that are easy to analyze further. We use recycling BiCG in the Iterative Rational Krylov Algorithm (IRKA) for interpolatory model reduction and in the VMC algorithm. For a model reduction problem, we show up to 70% savings in iterations, and we also demonstrate that solving the problem without recycling leads to (about) a 50% increase in runtime. Experiments with recycling BiCG for VMC gives promising results. We also present an algorithm that recycles preconditioners, leading to a dramatic reduction in the cost of VMC for large(r) systems. The main cost of the VMC method is in constructing a sequence of Slater matrices and computing the ratios of determinants for successive Slater matrices. Recent work has improved the scaling of constructing Slater matrices for insulators, so that the cost of constructing Slater matrices in these systems is now linear in the number of particles. However, the cost of computing determinant ratios remains cubic in… Advisors/Committee Members: De Sturler, Eric (committeechair), Beattie, Christopher A. (committee member), Borggaard, Jeffrey T.

Nous effectué des réactions de cyclisations [3 +2] énantiosélectives entre des allénoates et des énones, catalyseées par des phosphines, donnant accès à des hétérocycles soufrés présentant des motifs moléculaires spirocycliques porteurs de nombreux centres asymétriques. De bons rendements chimiques et des bon excès énantiomériques ont été obtenus en utilisant le (S,S)-FerroPHANE comme le catalyseur chiral.D’autre part, nous avons développé de nouvelles réactions catalysées par les phosphines donnant accès à des hétérocycles azotés. En tenant de la réactivité des phosphines connue dans la Littérature, nous avons envisagé des substrats permettant la combinaison de différents processus catalytique.Des réactions de cyclisation [3+2], catalysées par les phosphines, entre des imines et des diènes conjugués, doublement activés à leurs extrémités, permet d’accéder en une seule étape à des 3-pyrrolines tri-substituées de manière diastéréosélective. Nous avons alors évalué les possibilités et limitation de cette nouvelle voie d’accès aux pyrrolines en mettant en jeu de toute une gamme de diènes et d’imines diversement fonctionnalisés.Nous avons ensuite étudié ce nouveau mode de cyclisation en utilisant des diènes où l’une des deux insaturations est inscrite dans un cycle. Dans le cas de ces substrats cycliques, des composés portant le motif hexahydroisoindol-4-one ont été obtenus de manière très efficace.Enfin, il a été montré que des diènes portant le motif coumarine réagissaient avec des imines en présence de quantités stœchiométriques de phosphine et d'eau pour donner lieu à un processus domino sans précédent: une réaction de aza-Morita-Baylis Hillman suivi d’une réaction de réduction. Ce processus s'est avéré très chimiosélectif et procède avec un excellent contrôle des configurations relatives des deux centres asymétriques contigus nouvellement formés.L’ensemble de ces études ont permis de mettre en valeur l’efficacité de la catalyse par les phosphines nucléophiles pour la formation d’hétérocycles soufrés et azotés, structurellement diversifiés et hautement fonctionnalisés, à partir de matières premières facilement accessibles.

We have applied the enantioselective [3+2] cyclisations between allenoates and enones, under phosphine catalysis, to the asymmetric synthesis of sulfides and sulfoxides displaying unprecedented spirocyclic molecular scaffolds and multiple stereocentres. Notably, good yields and e.e’s were obtained by using (S,S)-FerroPHANE as the chiral catalyst. Then, we established a highly diastereoselective oxidation procedure which converts the enantiomerically enriched spirocyclic sulfides into the corresponding sulfoxides. On the other hand, we have developed new phosphine promoted reactions for the synthesis of nitrogen heterocycles. From the known modes of action of phosphine nucleophiles, we have designed new combinations of properly functionalized substrates that have been processed in the presence of phosphorus catalysts. The [3+2] annulation reaction between imines and acyclic conjugated dienes,…

▼ Earthquakes can pose a serious threat to people and their environment. Natural earthquakes have the potential to be disastrous and mostly occur unexpectedly. Induced earthquakes caused by anthropogenic activities are commonly less disastrous, but can be a great nuisance and are increasingly attracting public attention. The physical processes behind seismicity are not understood well enough to predict natural earthquakes or to completely control induced earthquakes. Estimates about the future occurrence of earthquakes are typically very uncertain, which makes it difficult to use these estimates for mitigation strategies. These restrictions partially arise from the limited resolution of available data and analyses. This thesis will address these limits two-fold. First, it presents a holistic approach for natural earthquake sequences that translates the typically very low earthquake occurrence probabilities into risk estimates—these might reach intolerable levels and justify mitigation actions; in the broadest sense, these may save lives. Secondly, it presents a fundamental approach to produce a high-resolution earthquake catalog of consistent quality using a sensitive detection method and dedicated post-processing; this approach detects very small earthquakes and offers new possibilities for seismicity analyses. The first contribution in this thesis describes an alternative risk mitigation strategy based on probabilistic risk forecasting and cost–benefit analysis, which can support objective short-term evacuation decisions. We apply this approach to a scenario earthquake sequence that simulated a repeat of the 1356 Basel earthquake (∼Mw6.7), one of the most damaging events in central Europe. Based on this simulated sequence, we explore how to possibly provide decision support and information throughout an earthquake crisis. We forecast earthquake consequences, specifically quantified in terms of human loss. The final cost–benefit analysis adds value beyond making probabilistic forecasts: it provides objective statements that may justify evacuations. Compared to an earlier study, we incorporate recent developments in short-term earthquake forecasting and more detailed settlement data to permit spatial forecasts and district-wise decision-making. These new ingredients permit an increased spatial resolution for the decision support and have the potential to improve the cost-effectiveness of mitigation actions. For instance, the occurrence of an M5.5 earthquake or larger would justify evacuations in the central part of the city of Basel, Switzerland. To deliver such supportive information in a simple form, we propose a warning approach in terms of alarm levels. The second contribution in this thesis describes the development and analysis of a consistent high-resolution earthquake catalog of induced seismicity in the Enhanced Geothermal System (EGS) in Basel.

▼ As circuit size grows, the need of correct circuit functioning imposes a testing methodology to be applied to ensure proper behavior of that circuit after manufacturing. Towards that direction, Test Pattern Generation procedures are devised to validate the circuit function. These procedures produce sets of input vectors (test sets) that when applied to circuit inputs produce output responses that enable one to check the "correct" circuit functioning. In this dissertation we elaborate on efficient Automatic Test pattern generation methods for digital circuits. Test pattern generation methods differentiate between those that operate on a combinational circuit and those operating on sequential circuits. For combinational circuits, the circuit under test (CUT) with all the ATPG constraints is represented here by a neural network. This neural network is characterized by an energy function E that has global minimum (=0) only at the neuron states consistent with circuit’s logic function. With the help of the energy function E the ATPG problem for combinational circuits is formulated, in this work, as an energy minimization problem where we attempt to find the global minimum of the energy function. For this purpose, are developed: a) a method of gradient descent search where the studying of the surface of the energy function revealed a saddle point and the research focused on the use of saddle point as a starting point of the search process. b) A method that tries to find the solution (test vector) by using the transitive closure of the implication graph based on the energy function constraints. Furthermore, a parallel ATPG which is based on method b) is developed and implemented on a Network of Transputers. For sequential circuits, where a sequence of input vectors (test sequence) is required to detect a single fault the complexity of sequential circuit test generation is much higher than for combinational circuits. To cope with the complexity of sequential circuit test generation ATPG methods are developed which use Genetic Algorithms (GAs) for simulation-based test generation. In this work, it is ascertained that the current GA-based sequential test generators don’t take into consideration the following remarks: In a sequential circuit: a) it is very difficult, if not impossible, to identify the good "genes" of the circuit. b) Crossover operator which is responsible for the inheritance of good genes acts as a mutation operator. c) During the evolutionary process, "good" sequences survive while "weak" sequences are discarded though certain "weak" sequences may carry useful information about faults and/or states. States reached by "weak" sequences may be difficult for the "good" ones to reach and certain faults detected by them may be difficult to be detected in latter passes. Taking into consideration the above remarks, GA-based ATPG algorithms are devised that: a) Employ (GATPG algorithm) a crossover operator with a non-uniform probability distribution for the cut-point selection in order to preserve, as much as possible,…

▼ The iron cycle on the early earth was significantly different from today due to anoxic oceans and atmosphere. Today, the iron-rich deposits found show proof of this distinct cycle. For a long time, iron formations have been of particular interest because of their economic value and Fe isotopes were used to trace sources and depositional processes. Other sediments from the Precambrian are also distinctively iron-rich and might reflect iron cycling. Here, we present bulk iron isotope measurements of rocks from the Middle Mapepe formation of the Fig-Tree group from the Barb 5 drill core, Barberton Greenstone Belt, South Africa. 42 selected reference samples represent the basin development of the Middle Mapepe from deep anoxic to shallow water settings, including alluvial fans. Iron in the samples was chemically separated from its matrix and analysed for δ56Fe (relative to IRMM-014) with a MC-ICPMS at the Vrije Universiteit (VU) Amsterdam. Values ranged from -0.46‰ to 0.42‰ and showed a trend with negative values at the bottom of the core and more positive values at its top. This trend is interpreted to reflect variations in sedimentation and geochemical cycling in the Mapepe basin induced by changes in basin topography. Negative δ56Fe at the bottom of the core represent incorporation of isotopically light iron in diagenetic minerals, including pyrite, with only minor mixing with sediment input. In contrast, more positive values towards the top of the core suggest a stronger influence of detrital iron derived from weathering of mainly igneous rocks. This is mixed with iron that is withdrawn from the water column by an increasingly active anoxygenic photosynthesis in shallow conditions. A negative excursion of δ56Fe in a unit dominated by volcanoclastic debris coincided with a negative excursion in δ34S and an increase in inorganic carbon. This indicates active sulphur cycling and sulphide production by bacterial sulphur reduction and related Fe withdrawal and pyrite formation.
