Abstract:
Sparse reflectivity inversion of processed reflection seismic data is intended to produce reflection coefficients that represent boundaries between geologic layers. However, the objective function for sparse inversion is usually dominated by large reflection coefficients, which may result in unstable inversion for weak events, especially those interfering with strong reflections. We have determined that any seismogram can be decomposed according to the characteristics of the inverted reflection coefficients that can be sorted and subset by magnitude, sign, and sequence, and new seismic traces can be created from only reflection coefficients that pass the sorting criteria. We call this process reflectivity decomposition. For example, original inverted reflection coefficients can be decomposed by magnitude, large ones removed, the remaining reflection coefficients reconvolved with the wavelet, and this residual reinverted, thereby stabilizing inversions for the remaining weak events. As compared with inverting an original seismic trace, subtle impedance variations occurring in the vicinity of nearby strong reflections can be better revealed and characterized when only the events caused by small reflection coefficients are passed and reinverted. When we apply reflectivity decomposition to a 3D seismic data set in the Midland Basin, seismic inversion for weak events is stabilized such that previously obscured porous intervals in the original inversion can be detected and mapped, with a good correlation to the actual well logs.

Abstract:
Abstract Chromosomal inversions are among the primary drivers of genome structure evolution in a wide range of natural populations. Although there is an impressive array of theory and empirical analyses that have identified conditions under which inversions can be positively selected, comparatively little data are available on the fitness impacts of these genome structural rearrangements themselves. Because inversion breakpoints can disrupt functional elements and alter chromatin domains, the precise positioning of an inversion’s breakpoints can strongly affect its fitness. Here, we compared the fine-scale distribution of low-frequency inversion breakpoints with those of high-frequency inversions and inversions that have gone to fixation between Drosophila species. We identified a number of differences among frequency classes that may influence inversion fitness. In particular, breakpoints that are proximal to insulator elements, generate large tandem duplications, and minimize impacts on gene coding spans which are more prevalent in high-frequency and fixed inversions than in rare inversions. The data suggest that natural selection acts to preserve both genes and larger cis-regulatory networks in the occurrence and spread of rearrangements. These factors may act to limit the availability of high-fitness arrangements when suppressed recombination is favorable.

Abstract:
Conventional full-waveform seismic inversion attempts to find a model of the subsurface that is able to predict observed seismic waveforms exactly; it proceeds by minimizing the difference between the observed and predicted data directly, iterating in a series of linearized steps from an assumed starting model. If this starting model is too far removed from the true model, then this approach leads to a spurious model in which the predicted data are cycle skipped with respect to the observed data. Adaptive waveform inversion (AWI) provides a new form of full-waveform inversion (FWI) that appears to be immune to the problems otherwise generated by cycle skipping. In this method, least-squares convolutional filters are designed that transform the predicted data into the observed data. The inversion problem is formulated such that the subsurface model is iteratively updated to force these Wiener filters toward zero-lag delta functions. As that is achieved, the predicted data evolve toward the observed data and the assumed model evolves toward the true model. This new method is able to invert synthetic data successfully, beginning from starting models and under conditions for which conventional FWI fails entirely. AWI has a similar computational cost to conventional FWI per iteration, and it appears to converge at a similar rate. The principal advantages of this new method are that it allows waveform inversion to begin from less-accurate starting models, does not require the presence of low frequencies in the field data, and appears to provide a better balance between the influence of refracted and reflected arrivals upon the final-velocity model. The AWI is also able to invert successfully when the assumed source wavelet is severely in error.

Abstract:
Using a fast 2-D inverse solution, we examined the resolution of different resistivity/IP arrays using noisy synthetic data subject to minimum structure inversion. We compared estimated models from inversions of data from the dipole‐dipole, pole‐dipole, and pole‐pole arrays over (1) a dipping, polarizable conductor, (2) two proximate conductive, polarizable bodies, (3) a polarizable conductor beneath conductive overburden, and (4) a thin, resistive, polarizable dike. The estimated resistivity and polarizability models obtained from inversion of the dipole‐dipole data were usually similar to the pole‐dipole estimated models. In the cases examined, the estimated models from the pole‐pole data were more poorly resolved than the models from the other arrays. If pole‐pole resistivity data contain even a fraction of a percent of Gaussian noise, the transformation of such data through superposition to equivalent data of other array types may be considerably distorted, and significant information can be lost using the pole‐pole array. Though the gradient array is reputed to be more sensitive to dip than other arrays, it evidently contains little information on dip that does not also appear in dipole‐dipole data, for joint inversion of dipole‐dipole and gradient array data yields models virtually identical to those obtained from inversion of dipole‐dipole data alone.

Abstract:
We present a general formula for the back projection of traveltime residuals in traveltime tomography. For special choices of an arbitrary weighting factor this formula reduces to the asymptotic back‐projection term in ray‐tracing tomography (RT), the Woodward‐Rocca method, wavepath eikonal traveltime inversion (WET), and wave‐equation traveltime inversion (WT). This unification provides for an understanding of the differences and similarities among these traveltime tomography methods. The special case of the WET formula leads to a computationally efficient inversion scheme in the space‐time domain that is, in principle, almost as effective as WT inversion yet is an order of magnitude faster. It also leads to an analytic formula for the fast computation of wavepaths. Unlike ray‐tracing tomography, WET partially accounts for band‐limited source and shadow effects in the data. Several numerical tests of the WET method are used to illustrate its properties.

Abstract:
This paper presents a multilayer generalization of an algebraic method of inverting frequency‐doma in airborne active electromagnetic (AEM) data in terms of 1-D layered earth models. The processing of the AEM data, which includes a recalibration procedure, is also outlined. The inversion is applied to synthetic fields generated from a multilayer model which is intended to approximate a measured conductivity profile of the water column in the Gulf of Mexico and to measured AEM data from a survey of the Barataria Bay estuary region of the Louisiana Gulf of Mexico coast. The inversion results from the synthetic data are in good agreement with the forward model. The conductivities calculated from the inversions of measured AEM data are compared to ground‐and water‐based measurements. The depth variations of the calculated electrical conductivities in the nearshore Gulf waters are in good agreement with measurements of conductivity versus depth by conductivity‐temperature‐depth (CTD) casts at several points on the over‐the‐water portion of two flight lines.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Linguistics and Philosophy, 2008.
Includes bibliographical references (leaves 158-165).
In this thesis I examine some of the fundamental questions surrounding inversion structures. I first provide an analysis of Locative Inversion. I show that the mixed A- and A- syntactic behavior of the fronted PP in English could be derived once we understand how the featural composition of locative phrases influences on the Probe-Goal relation between C and the postverbal DP. In particular, I argue that there is a correlation between syntactic categories of locative phrases and typological differences in the syntactic patterns in Locative Inversion: in Mandarin Chinese, Chichewa, Kinande and Gungbe, locatives are (or can be) represented by nominal categories (i.e. equipped with complete cp-features) and these locatives exhibit pure A-properties in Locative Inversion; in English and Sesotho, however, they are characteristically represented by non-nominal categories and the locative phrases are thus forced to undergo two-step movement from an Aposition to an A-position as avoidance of intervention effects in the Agree system.I also discuss a variety of (generalized) inversion constructions, including English Quotative Inversion, Sentential Subject and French Stylistic Inversion. In these constructions I show that since a cp-deficient constituent moves to [Spec, TP], additional operations (such as topicalization) have to take place so as to destroy the potentially offending structure created by the fronted defective elements.
(cont.) Specifically, I suggest that these are related constructions because they all display a mixture of A- and A- properties.Finally I focus on the generalization concerning the placement restrictions of arguments by Spell-Out, in particular the principles that force argument externalization from the vP and VP. I argue that argument externalization is motivated by Case-related concerns.

Abstract:
Amplitude-versus-offset, AVO, approximations allow the estimation of various properties from pre-stack seismic gathers. Recently it has been suggested that fluid mobility is a controlling factor in pore pressure equalisation and can result in anomalous velocity dispersion in the seismic bandwidth. However, current approximations all assume an elastic subsurface and are unable to account for velocity dispersion. I have applied existing methodologies to a real dataset to qualitatively detect and interpret spectral amplitude anomalies. Three areas had AVO and spectral signature consistent with frequency-dependent AVO theory. The results suggest that it is feasible to measure such effects on real data in the presence of random noise. It would imply that the relaxation parameter, tau, is larger in the field than has been measured in water-saturated real and synthetic sandstones in the laboratory. I extended a two-term AVO approximation by accounting for velocity dispersion and showed how the resultant reflection coefficient becomes frequency-dependent. I then used this to measure P- and S-wave reflectivity dispersion using spectrally-balanced amplitudes. The inversion was able to quantify the affect of the P-wave velocity dispersion as an instantaneous effect on the reflection. NMO stretch was an issue at the far offsets and I limited myself to the near offsets and effectively measured only the P-wave reflectivity dispersion. I showed how the P-wave reflectivity dispersion signs depend on the AVO classification of the reflection whilst the magnitude depends on the crack density of my model. I showed how the effect of noise and thin-bed tuning can enter uncertainties into the interpretation of spectral anomalies. Whilst it is possible to detect frequency-dependent AVO signatures on pre-stack gathers, the interpretation remains non-unique. I have quantitatively measured a new physical property, reflectivity dispersion, from pre-stack seismic data. I have presented a method of detecting and measuring velocity dispersion in pre-stack gathers but there remain ambiguities in the interpretation of such results. The approach incorporates spectrally decomposed data in an extended AVO inversion scheme. Future work should investigate the application of the methodology to a real seismic dataset.

In this thesis, we investigate two expressions for symmetric group characters: Kerov?s universal character polynomials and Stanley?s character polynomials. We give a new explicit form for Kerov?s polynomials, which exactly evaluate the characters of the symmetric group scaled by degree and a constant. We use this explicit expression to obtain specific information about Kerov polynomials, including partial answers to positivity questions. We then use the expression obtained for Kerov?s polynomials to obtain results about Stanley?s character polynomials.

Abstract:
I implemented and tested the method of Non-Linear Conjugate Gradients (NLCG) to invert magnetotelluric (MT) and radiomagnetotelluric (RMT) data in two dimensions. The forward problem and the objective function gradients were computed using finite-difference methods. The NLCG algorithm was applied to three field data sets to test the performance of the code. It was then compared to the inversion techniques of Occam and damped Occam considering the quality of the output resistivity models and the computation times. The implemented code was further investigated by testing two line search techniques to reduce the objective function along a given search direction. The first line search procedure was constrained to the first Wolfe condition, leading to a rather inexact line search. The second, more thorough line search, was additionally constrained to the second Wolfe condition. Three preconditioners were applied to the NLCG algorithm and their performance was analysed. The first preconditioner was set to the diagonal of the approximate Hessian matrix and updated every 20-th iteration. Preconditioners two and three were updated with the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm using the identity matrix and the diagonal of the approximate Hessian matrix as start preconditioners, respectively. The tests showed that the method of NLCG is more efficient pertaining to computation times compared to the Gauss-Newton (GN) based techniques (Occam and damped Occam). For the two smaller data sets that were inverted, the NLCG inversion was two to four times faster than Occam and damped Occam. For the larger data set, the NLCG inversion converged more than one order of magnitude faster than the GN based inversion techniques. This is because GN methods require to evaluate the entire sensitivity matrix to update the model, whereas NLCG only needs to compute a matrix-vector product of the Jacobian. Moreover, expensive operations such as matrix products and direct inversions of linearised systems are avoided by NLCG. A limitation of the NLCG algorithm is that it is prone to converge to local minima due to the fixed Lagrange multiplier that is used in the penalty function. Occam inversion, which determines the optimal Lagrange multiplier as part of the inversion, did not show such problems. The line search tests of the NLCG algorithm showed that an inexact line search yields higher convergence per CPU time than a more exact line search. In accordance to previous studies, preconditioning accelerated the convergence of the NLCG algorithm considerably. The preconditioners updated with the BFGS algorithm achieved highest convergence. Choosing the identity matrix as a start preconditioner led to fast but unstable convergence. The reasons for that could not be determined completely. Taking the diagonal of the approximate Hessian as a start preconditioner instead of the identity matrix led to slower convergence for most of the inversion tests, but convergence could be stabilised. All the tests performed within this project led to a robust implementation of the NLCG algorithm. A default set-up pertaining to line search and preconditioning could be established. However, the NLCG set-up can be adjusted by the user to improve convergence for a specific data set. This makes the algorithm implemented in this thesis more flexible than previously introduced NLCG codes. Preconditioning can certainly still be improved with further tests. Moreover, a future project will be to extend the 2D code to 3D, where NLCG should perform especially well, because the number of model parameters is usually higher in 3D.

Abstract:
Ce travail de recherche propose une solution aux problèmes inverses probabilistes avec des outils de la statistique bayésienne. Le problème inverse considéré est d'estimer la distribution d'une variable aléatoire non observée X a partir d'observations bruitées Y suivant un modèle physique coûteux H. En général, de tels problèmes inverses sont rencontrés dans le traitement des incertitudes. Le cadre bayésien nous permet de prendre en compte les connaissances préalables d'experts surtout avec peu de données disponibles. Un algorithme de Metropolis-Hastings-within-Gibbs est proposé pour approcher la distribution a posteriori des paramètres de X avec un processus d'augmentation des données. A cause d'un nombre élevé d'appels, la fonction coûteuse H est remplacée par un émulateur de krigeage (méta-modèle) H chapeau. Cette approche implique plusieurs erreurs de nature différente et, dans ce travail, nous nous attachons a estimer et réduire l'impact de ces erreurs. Le critère DAC a été proposé pour évaluer la pertinence du plan d'expérience (design) et le choix de la loi a priori, en tenant compte des observations. Une autre contribution est la construction du design adaptatif adapté a notre objectif particulier dans le cadre bayésien. La principale méthodologie présentée dans ce travail a été appliquée a un cas d' étude d'ingénierie hydraulique.

Abstract:
In this thesis I propose an explanation for the facts of copular inversion in Spanish, Catalan, and other Romance languages, as well as in German. Copular inversion is a phenomenon found in some languages, in which, at least superficially, the copula may be found agreeing with the postverbal DP instead of the preverbal DP. At first sight it appears that the agreeing postverbal DP is the subject of the sentence, but in this work I provide evidence that this is not the case: the agreeing postverbal DP is, in fact, the complement of the copula. This yields a singular case of non-subject agreement in Spanish, Romance and the rest of copular inversion languages that is not found in the rest of the grammar of these very same languages (e.g. they do not ever show object-agreement in transitive sentences). This requires an explanation that is integrated with the rest of the grammars of the languages. I claim that coreference is the driving force behind the presence of copular inversion: in copular inversion languages, all verbs actually seek agreement with it and all those grammatical functions that are coreferential with the subject. In intransitive and transitive sentences, the only possible candidate is the subject, but in copular sentences the complement is usually coreferential with the subject. The choice of the agreeing function among the possible candidates is decided with respect to a Person-Number Hierarchy: the copula will always agree with the function that has the most marked person and number agreement features with respect to it. This requires challenging the standard view of LFG by which the lexical entries of verbs determine the person and number features of the subject: the solution requires accepting that the person and number features of the verb must be represented in a function-independent “bundle” that is unified with the right grammatical function according to syntactic well-formedness constraints in an OT setting. Additionally to explain the facts of copular inversion languages, the proposed OT-LFG hypothesis predicts why other languages do not have copular inversion. Moreover, the proposed hypothesis can easily be extended to other phenomena of non-subject agreement, e.g. Catalan cleft sentences, Icelandic non-subject agreement in “quirky case” constructions, English locative inversion and agreement phenomena in the Dargwa family of languages.
En la presente tesis doctoral expongo una explicación para la inversión copulativa –presente en la mayoría de las lenguas romances como también en alemán–. Este fenómeno consiste, superficialmente, en que la cópula concuerda con el sintagma nominal posverbal en vez del preverbal. A primera vista, esto puede parecer simplemente que el sujeto se encuentra en posición posverbal, pero la evidencia que se presenta en este trabajo demuestra que ese sintagma posverbal no es el sujeto, sino el complemento del verbo. Por tanto, esta es una construcción singular en la que un verbo concuerda con un no-sujeto, con la misma morfología empleada para la concordancia con el sujeto, cosa absolutamente inusitada para la gramática de las lenguas analizadas –que carecen de cualquier tipo de concordancia verbo-objeto, por ejemplo–. Así pues, defiendo que la inversión copulativa es consecuencia del hecho de que la concordancia en estas lenguas es, en realidad, entre el verbo y alguna función gramatical que sea correferente con el sujeto, incluido el propio sujeto. Naturalmente, solo las oraciones copulativas poseen dos funciones correferentes con el sujeto –el sujeto y el complemento–, debido al significado de la cópula; en otros tipos de oraciones, la única función disponible es el sujeto, por lo cual el verbo solo puede concordar con este. La función con la cual se concuerda será aquella correferente con el sujeto cuyos rasgos de persona y número sean los más marcados según una Jerarquía de Persona y Número. Para ello, es absolutamente necesario abandonar la premisa de la Gramática Léxico-Funcional por la cual la concordancia del verbo se establece en su entrada léxica como una determinación de los rasgos de las funciones gramaticales concordantes. Aquí defiendo que los verbos simplemente determinan sus rasgos de concordancia, independientes de toda función gramatical, y que estos son unificados con los rasgos de una u otra función o funciones según restricciones formales de la gramática que, en este trabajo, se estipulan en un marco teórico inspirado en la Teoría de la Optimidad. Esto me permite explicar por qué existen lenguas como el inglés que carecen de dicha construcción e, incluso, explicar fácilmente otros fenómenos de concordancia verbal con no-sujetos en otras lenguas, como, por ejemplo, en islandés en construcciones de sujeto en caso oblicuo, en la inversión locativa presente en inglés y en general en las lenguas dargwa.
