▼ In California, a vast population and agricultural industry rely on groundwater for their main water supply source. Recent drought conditions have placed a higher demand on groundwater resources, and in order to preserve this resource for future use, groundwater must be managed carefully. In areas where oil fields are located, there is concern that petroleum extraction operations and produced wastewater disposal are negatively impacting groundwater that may qualify as protected. To protect these waters, it is essential to know their location and extent. To accomplish this, we develop maps that locate the distribution of groundwater containing less than 10,000 parts per million (ppm) total dissolved solids (TDS) since these waters are more likely to qualify as protected. To map groundwater TDS at the Midway-Sunset oil field, we use the Stephens et al., [2018] method which relies on produced water geochemical measurements, TDS calculated using the RP method, and ordinary kriging. However, unlike the areas mapped by Stephens et al., [2018], the Midway-Sunset oil field presents unique challenges to mapping groundwater TDS. At the Midway-Sunset oil field, decades of enhanced oil recovery operations have led to significant variations in the geothermal gradient, while detrital diatomite in the sediments causes geophysical porosity logs to overestimate total porosity. This is a problem because TDS calculations require resistivity, temperature, and porosity data. The following thesis addresses these challenges to mapping groundwater TDS at Midway-Sunset in several key ways. Thermal effects from enhanced oil recovery were removed by only considering a subset of wells that were unaffected by thermal processes while three different porosity models were developed and tested for different regions of the field in order to remedy the diatomite-porosity-problem. The resulting calculated TDS values were then combined with existing geochemical measurements of TDS and kriged to generate salinity maps and cross sections for the Midway-Sunset oil field. In the northern portion of the field, the TDS maps and cross sections reveal that the depth to the 10,000 ppm TDS boundary extends to greater than ~-1500 feet elevation, while in the southern region the boundary is much shallower, with a maximum depth of ~150 feet elevation. In the study area, stratigraphy, faults, and freshwater recharge appear to control the distribution of groundwater TDS. Advisors/Committee Members: Shimabukuro, David.

▼ Las lateritas niquelíferas son una fuente generadora de la materia prima del acero inoxidable, el níquel. Dicho elemento se encuentra presente en diferentes tipos de rocas que son formadas por procesos externos que alteran, meteorizan y por último transforman la roca madre del depósito. La presencia de diferentes tipos de rocas, desde el punto de vista físico, químico, mecánico y, por último, de su contenido en mineralización en porcentajes (%) de níquel, hierro, magnesio, sílice, alúmina, entre otros, sugiere que cada tipo de roca debe estudiarse en forma propia. Cada perfil de meteorización o dominio geológico, conformado por diferentes tipos de rocas, tiene un comportamiento geoespacial diferente debido al proceso geológico de formación y enriquecimiento del depósito. Surge entonces la pregunta de cómo diseñar una metodología para muestrear el perfil de meteorización para la optimización de la malla de muestreo a corto plazo, partiendo del muestreo realizado en exploración, para generar el respectivo modelo de recurso. La metodología que se propone para determinar la malla de muestreo a corto plazo en lateritas niquelíferas, es la siguiente: análisis exploratorio y variográfico de datos espaciales, seguido de la construcción de múltiples escenarios mediante simulación Gaussiana secuencial y, a partir de los escenarios obtenidos, categorización de los recursos en cada dominio geológico usando gráficos tonelaje-ley sobre una ley de corte vs coeficiente de variación condicional (CCV). Lo anterior se aplica a varias mallas de muestreo tentativas para cada dominio geológico y permite estudiar y analizar la relación CBNT (relación costo/benefico, número-tiempo de muestras preparadas-analizadas en el laboratorio, tiempo en perforar cada dominio con su respectiva malla propuesta) para determinar la malla óptima de corto plazo en cada dominio. Se ilustra la propuesta con un caso de estudio de una zona particular de una laterita niquelífera subdividida en tres dominios geológicos que cubren todo el perfil de meteorización.

Dissertação de Mestrado em Sistemas de Informação Geográfica

De modo a classificar as linhas de alta e média tensão em Portugal continental, recorreu-se a estudo levado a cabo pela Quercus e pela SPEA, que reúne dados relativos a amostragem de mortalidade causada por electrocussão e colisão de aves. Recorrendo estes dados e a um conjunto de variáveis geográficos e biológicos realizou-se um processo de análise em componentes principais com o objectivo de condensar a informação contidas nas variáveis. Para a produção dos mapas de previsão de perigosidade das linhas eléctricas utilizou-se o Geostatistical Analyst (ARcMap9.2). O modelo que apresentou melhores resultados após a realização dos testes foi o Exponencial, e foi utilizado na produção dos mapas de previsão segundo dois conjunto de factores: geográficos; e ambientais. A análise da qualidade do modelo e consequentemente dos mapas foi realizada em termos de erros dos resíduos, onde se provou a bom ajuste do modelo. As linhas que apresentam maior perigosidade em termos de electrocussão localizam-se no centro norte do território nacional, enquanto que as linhas mais perigosas para a colisão se situam sobretudo no litoral.

In order to sort the powerline of high and medium voltage in Portugal, it was used a study carried out by Quercus and SPEA, which gathers data on the sampling of mortality caused by collision and electrocution in birds. Using these data and a set of geographic and biological variable, carried out a review process on the principal components in order to condense the information contained in the variables. For the production of the forecast maps of danger from power lines was used the Geostatistical Analyst (ARcMap9.2). The model showed better results after the testing was exponential and was used in the production forecast maps second set of two factors: geographic, and environmental. The analysis of the quality of the model and therefore of the maps was performed in terms of errors of the waste, which proved the good fit of the model. The lines that are more in danger of electrocution are located in the central north of the country, while the lines more dangerous to the collision are located mostly along the coast.

▼ The spatial and temporal variation of soil properties was evaluated on three sites in close proximity to Bayou Wikoff, St. Landry Parish, Louisiana. A total of 1,068 surface (0-5 cm) samples were collected, geo-located, and transported to Louisiana State University for physical and chemical analyses. Physical and chemical properties were spatially and temporally displayed using ArcGIS. Interpolation techniques such as spline, kriging, and inverse distance weighting were evaluated to determine the best fit model for the project. Spline and inverse distance weighting were found to be the least accurate interpolation models. Kriging provided the most accurate model of spatial and temporal data distribution. Clay content (for total suspended solid control), P levels, and organic C % were a primary focus for this study, as potential non-point source pollution threats to water quality in Bayou Wikoff. All three sites were evaluated individually, as each had unique management practices. Pasture Site 1 exhibited larger concentrations of nutrient deposition proportional to increasing organic C % and clay content in areas of lower elevation. These areas were nearest to the bayou and potentially allowed for runoff, reducing water quality. Pasture Site 2 has artificial swale formations that affected the distribution of the evaluated properties. Extensive research at this site exhibited patterns of nutrient distribution that correlated with the swale formations. In the low portion of the swale, clay content, organic C %, and corresponding nutrient concentrations increased. The Pristine Site, used as a control site, showed evidence that the surface soil (0-5cm) was heavily altered from natural deposition as a result of being turned, moved, or replaced. Overall, spatial and temporal assessments revealed that while the three sites have unique distribution patterns of clay and organic C %, the soils are not hazardous for water quality. However, best management programs should focus on swales and low lying areas to determine the affect of spatial variability.

▼ Nanotechnology products have long since made their way to markets around the world increasing the concerns about whether nanomaterials pose a risk to our environment or health. It has been suggested that engineered nanomaterial (ENM) with broad applications and rapid commercialization need better risk assessment and regulation. However, the refinement of regulations to deal with ENMs is limited by the time consuming and costly nature of in vivo and in vitro toxicity testing. In silico methods offer an inexpensive and rapid mechanism to integrate data from in vitro and in vivo testing and to ultimately predict their toxicity without the need for toxicological evaluations. Quantitative structure activity relationships (QSARs) can be developed to correlate descriptors of chemical compounds with their biological activities to inform risk assessments. As one of the most widely used additives in paints, sunscreens and electronic devices, zinc oxide nanoparticles (NP) are expected to increase in our environment. Some computational models have been established for simple bare metal NPs; however, none to date have focused on surface modified ZnO NPs. The goal of this project was to use NP toxic response data and determine if the inherent NP surface modification has a predictable effect on toxicity. To assess for hazardous effects caused by ZnO NPs, embryonic zebrafish were selected as vertebrate test species as their transparent tissues allow for easy visual assessment of multiple developmental malformations and their short life span allows for rapid assessments. The physicochemical properties of NP surface modifications were calculated with consideration of fish water pH and electrolyte concentrations. Principal component analysis (PCA) and ordinary kriging (OK) methods were applied to develop our model. To test our model for prediction of more complicated ZnO NPs, we selected 2 additional ZnO NPs that were doped with Fe₂O₃ or Al₂O₃, and determined if they matched our toxicity estimations. Based on this strategy, ENM toxicity could be rapidly estimated from label information and wide range of kriging maps with increasing support from our publically available knowledgebase and global collaborations.

▼ There is a present need for post-processing tools capable of synthesising and interpreting the numerous spatial data that are typically generated in modern investigations of fluid mechanics. Recent advances have provided both the analyst and the experimentalist with powerful tools for resolving complete flow-field information, using Computational Fluid Dynamics to simulate the flow, or noninvasive flow metrology such as Particle Image Velocimetry and Laser Doppler Anemometry. A great deal of nodal data is generated by these techniques, which quantity may be expected to increase into the future. This data comprises uncertainties in both numerical modelling and experimental measurement, which traditionally have been quantified using classical approaches in Verification and Validation. However, these techniques were designed with summary scalar values in mind and generally overlook or underestimate the importance of suitable spatial and topological description of the flow-field. The author uses established techniques in geostatistics to address the fluids data assimilation problem, and cross-correlate spatial field variables collected over an experimental domain with field variables calculated by a numerical model that simulates this domain. Spatial statistics are generated on the inter-related nodal data, and are used to inform a stationary covariance model describing the datasets as a particular realisation of a random process. This model is used to provide statistics quantifying the correlation of complete experimental and numerical flow-fields, and make better estimations of local field values taking into account the sum data that is available to the practitioner. Special consideration is given to the application of the random function model to a calculated flow-field, in which errors are not aleatoric but epistemic, and comprise unknown chaotic processes and higher-order error terms. The kriging estimator was useful for the characterisation of the spatial datasets considered, and may be expected to extend quite generally to other fluids problems. In particular, meaningful blending of experimental and numerical data was achieved by cokriging, and is demonstrated in situations where experimental data is missing or sparse but may be inferred by the secondary numerical data with which it is well correlated. A statistic describing whole-field correlation on the basis of functional covariance was also proposed for fluids problems, with reference to which it is demonstrated that traditional pointwise measures of disparity are inadequate for spatial problems.

▼ Stochastic kriging is a popular metamodeling technique for constructing response surfaces of complex stochastic simulation models in a variety of disciplines including queueing simulation, financial risk management, insurance product pricing, etc. And it is well known that incorporating gradient information can significantly enhance the prediction accuracy of stochastic kriging, such as the gradient extrapolated stochastic kriging, which converts the gradient information to a “pseudo” observation of the response surface by linear extrapolation to expand the number of kriging points. However, such an enhancement cannot be scaled trivially to high-dimensional design space, since one needs to invert a covariance matrix of size n(d +1) x n(d +1) that captures the spatial correlations between the responses and the gradient estimates at the design points, where d and n are the dimensionality and the number of design points, respectively. Not only is the inversion computationally inefficient, but also numerically unstable since the covariance matrix is often ill-conditioned. We address the scalability issue via a novel approach without resorting to matrix approximations. By virtue of the so-called Markovian covariance functions, the associated covariance matrix can be invertible analytically, thereby improving both the efficiency and stability dramatically. We extend this methodology to the setting where gradient estimators are available, thereby making the gradient-enhanced stochastic kriging metamodel scalable. Numerical experiments, including analytical cases and practical cases, demonstrate that the idea of integrating gradient information with SK can handle large-scale problems where prior methods fail completely. In addition, we consider the case that with limited computing budget and non-constant intrinsic variance among large-scale response surface, we can also apply some optimal simulation allocation strategies to improve the prediction accuracy of both stochastic kriging and gradient extrapolated stochastic kriging, numerical experiments are conducted to prove our argument.

▼ In an effort to support the Kyoto Protocol, the government of the United Kingdom has targeted a goal of obtaining 15% of its electricity supply from renewable sources by 2015. To reach such standards, primary concentration has been placed on renewable sources from the marine environment. However, with increases in the numbers of offshore renewable energy developments (OREDs), proper monitoring and analysis techniques must be established to evaluate the potential impacts these structures and their overall environmental footprint will pose on the marine ecosystem, particularly species distribution. Monitoring techniques have been established by offshore energy developers; however, such methods currently only evaluate animal distribution trends in the short term both pre and post construction. In this study, spatio-temporal analysis of catch per unit effort (CPUE) data was undertaken, utilising geostatistics to enable long term trends to be evaluated for four elasmobranch species common to the North Sea over the 1990-2011 survey period. Overall, the mean CPUE was found to remain stable for all species. However, distribution trends were found to vary throughout the periods examined. Such trends were often correlated to migrating seasons, as well as the habitat preferences for each species. The presence of offshore wind farms and electromagnetic fields associated with subsea cable networks may affect elasmobranch migratory patterns and small-scale orientation. As these species are already vulnerable to overfishing, habitat disruption, and anthropogenic disturbance due to their long life history and low fecundity, consistent monitoring periods and survey locations are essential to their conservation and protection. It is, therefore, unlikely short monitoring periods will provide accurate information on the potential impacts offshore energy developments may have on elasmobranch populations. The approach used is generic enough to provide a basis on which to analyse spatial distribution of organisms in relation to other sources of anthropogenic influence, and environmental parameters.

▼ Accurate and timely information on road weather and surface conditions in winter seasons is a necessity for road authorities to optimize their winter maintenance operations and improve the safety and mobility of the traveling public. One of the primary tools for acquiring this information is road weather information systems (RWIS). While effective in providing real-time and near-future information on road weather and surface conditions, RWIS stations are costly to install and operate, and therefore can only be installed at a limited number of locations. To tackle this challenging task, this thesis develops various different approaches in an attempt to determine the optimal location and density over a regional highway network. The main research findings are summarized as follows. First, a heuristic surrogate measure based method (SM) has been developed. Two types of location ranking criteria are proposed to formalize various processes utilized in the current practice, including weather and traffic related factors. Consideration of these two types of factors captures the needs to allocate RWIS stations to the areas with the most severe weather conditions and having the highest number of traveling public. A total of three location selection alternatives are generated and used to evaluate the current Ontario RWIS network. The findings indicate that the current RWIS network is able to provide a reasonably good coverage on all location criteria considered. Second, a cost-benefit based method (CB) has been proposed to give an explicit account of the potential benefits of an RWIS network in its location and density planning. The approach has been constructed on a basis of a sensible assumption that a highway section covered by an RWIS station is more likely to receive better winter road maintenance (WRM) operations. A case study based on the current RWIS network in Northern Minnesota show that the highest projected 25-year net benefits are approximately $6.5 million with cost-benefit ratio of 3.5, given the network of 45 RWIS stations. Third, a more comprehensive and innovative framework has been developed by using the weighted sum of average kriging variance of winter road weather conditions. Methodologically, the formulation of the RWIS location optimization problem is foundational with several unique features, including explicit consideration of spatial correlation of winter road weather conditions and high travel demand coverage. The optimization problem is then formulated by taking into account the dual criteria representing the value of RWIS information for spatial inferences and travel demand distribution. The spatial simulated annealing (SSA) algorithm was employed to solve the combinatorial optimization problem ensuring convergence. A case study based on four study regions covering one Canadian province (Ontario), and three US states (Utah, Minnesota, and Iowa) exemplified two distinct scenarios –redesign and expansion of the existing RWIS network. The findings indicate that the method developed is very…

▼ Genetic algorithms are an attractive choice for researchers and practitionersof design optimization. Their advantages are many as compared to classicaloptimization approaches. However, there are a number of areas to look intoso as to make them more practically relevant. This thesis describes originalcontributions to three such areas – Robust Design Optimization, ConstraintHandling and Co-Kriging.Robust design optimization using genetic algorithms is computationally expensive because of the high number of function evaluations involved. Hence, it is often simply not possible to use such procedures in practice. We propose some enhancements to an existing robust design optimization algorithm by making it less resource intensive and hence more practically applicable. We study a number of Bi-objective Engineering design optimization problems to understand and demonstrate the benefits of the proposed enhancements. A highlight of this study is the robust design optimization study of an Axisymmetric Scramjet configuration. Next, an interesting and novel constraint handling technique based on the so-called Most probable point (of failure) is described. The proposed method is applicable to optimization problems with equality and active inequality constraints. We present the findings of the proposed approach by considering a test bed of a number of Single and Multi-objective optimization problems. The test bed consists of standard synthetic test problems and engineering design optimization problems. A key contribution here is theformulation of a number of Multi-objective equality constrained test problems.Finally, an interesting modification to Co-Kriging is proposed. Co-Kriging seeks to combine training data obtained at multiple levels of fidelity to enhance the performance of Kriging. It however introduces a number of additional hyper-parameters as compared to Kriging. Determining their optimal values is critical to obtaining a successful Co-Kriging model. A genetic algorithm based optimization technique to find the values of these hyper-paramaters is proposed. The proposed technique also does away withthe need to evaluate the likelihood functions and hence dealing with large data sets become more tractable. A number of mathematical examples demonstrate the application of the proposed technique. As a more practical example, data sets obtained from a Scramjet design optimization exercise is considered.The results presented as part of each of the above areas will clearly demonstrate the potential of the proposed techniques in making the use of genetic algorithms in design optimization more practical and viable. The findings also helped us in coming up with a number of avenues for future work in these directions which concludes this thesis.

▼ “En esta memoria se propone el uso de un software computacional como es el programa Excel, para construir un modelo geoestadístico para la complementación y generación de información hidrogeológica en la zona del Maipo medio, específicamente se desea obtener la permeabilidad en puntos definidos donde esta no es conocida. El “Excel” realizado es de fácil uso, ya que basta con introducir las coordenadas del punto donde se requiere información para que este entregue la permeabilidad estimada en ese punto. Para la generación de información hidrogeológica se utilizan datos de 83 pozos ya existentes en archivos de la DGA, los cuales se trabajan mediante un método geoestadístico llamado Kriging o Krigeado, el cual básicamente utiliza las distancias entre el punto que se desea estimar y los puntos en los cuales ya se conoce información para realizar la estimación. Para el Kriging se construye el variograma experimental el cual es la varianza de las diferencias de los valores de la variable regionalizada en las localizaciones separadas una distancia h, de este variograma construido sólo se toma el 39,5% para ajustar el variograma teórico. Se ajustan diferentes variogramas teóricos y se escoge finalmente el con menor varianza del error, el cual resulta ser el llamado modelo esférico, este posee una varianza del error de 0,0068, con un valor para el alcance de 1500 metros y una meseta de 0,27. Conociendo el variograma teórico con que se trabaja, se realiza la estimación con el método de Kriging. Para hacer esto se debe validar el modelo a utilizar, esto se hace mediante el método llamado live one out, consistente en eliminar uno de los puntos donde se tienen datos de la estimación y estimarlo mediante el resto de los datos, este procedimiento se realiza con todos los puntos de permeabilidad conocida, esperando un error bajo en las estimaciones para poder aseverar la correcta estimación del resto de los puntos requeridos. Esta validación arroja los siguientes resultados. Los cuales dan cuenta de una estimación correcta. Finalmente se concluye que para el área y datos propuestos es posible realizar una estimación confiable de la permeabilidad. Advisors/Committee Members: Barra Ortega, Leonel (advisor).

▼ A análise dos aspectos econômicos inerentes aos processos produtivos e o posicionamento das indústrias quanto a sua eficiência torna perceptível a importância de aumentar a produtividade e aperfeiçoar a utilização dos recursos. Nas indústrias de produção mecânica, em particular, aumentar a eficiência dos processos de usinagem é muito importante. Nesse contexto, somente ser capaz de selecionar ferramentas para um determinado componente não é suficiente para satisfazer as necessidades econômicas; a ferramenta ideal selecionada deve ser a mais eficiente de todas as disponíveis em um ambiente real. A influência do fenômeno de corte sobre o processo de usinagem é tradicionalmente o foco das pesquisas que relacionam os parâmetros de corte, porém, o estudo da vida de ferramentas de corte é alvo de pesquisas desde o início dos processos produtivos. Algumas das principais dificuldades relacionadas às pesquisas de estudo de vida de ferramentas de corte se relacionam ao custo com material e ao tempo envolvidos na obtenção dos dados experimentais. O uso do método tradicional apresentado por Kuljanic (1980) para a obtenção da equação de Taylor para vida de ferramenta consome muito tempo e recursos. Como uma alternativa à abordagem da experimental tradicional, a Krigagem, que é um método de interpolação linear desenvolvido na década de 1950, tem apresentado resultados promissores no tratamento de dados experimentais (GUNES, 2008). Este trabalho tem como objetivo a investigação do comportamento desta técnica de interpolação na obtenção da curva de vida da ferramenta de corte em função dos parâmetros de usinagem: a velocidade de corte, o avanço por rotação, e a profundidade de corte. São utilizados dados obtidos por simulação a partir de uma função de vida de ferramenta conhecida (acrescida de uma perturbação aleatória), com vistas a avaliar o comportamento da técnica de interpolação e investigar sua utilização para reduzir o número de experimentos necessários para obtenção da curva de vida de ferramenta. Os resultados deste trabalho mostram que é possível reduzir-se o número de ensaios sem que a perda de significância seja relevante. Advisors/Committee Members: Fabio Henrique Pereira.

Les chercheurs dans le domaine de la conception aérodynamique et de la fabrication des avions ont fait beaucoup d'effort pour améliorer les performances des ailes par des techniques d'optimisation. Le développement de la mécanique des fluides numérique a permis de réduire les dépenses en soufflerie tout en fournissant des résultats convaincants pour simuler des situations compliquées des aéronefs. Dans cette thèse, il a été choisi une partie spéciale et importante de l'avion, à savoir, la structure de l'aile. L'optimisation basée sur la fiabilité est une méthode plus appropriée pour les structures sous incertitudes. Il se bat pour obtenir le meilleur compromis entre le coût et la sécurité tout en tenant compte des incertitudes du système en intégrant des mesures de fiabilité au sein de l'optimisation. Malgré les avantages de l'optimisation de la fiabilité en fonction, son application à un problème d'ingénierie pratique est encore assez difficile. Dans notre travail, l'analyse de l'incertitude dans la simulation numérique est introduite et exprimée par la théorie des probabilités. La simulation de Monte Carlo comme une méthode efficace pour propager les incertitudes dans le modèle d'éléments finis de la structure est ici appliquée pour simuler les situations compliquées qui peuvent se produire. Pour améliorer l'efficacité de la simulation Monte Carlo dans le processus d'échantillonnage, la méthode de l'Hypercube Latin est effectuée. Cependant, l'énorme base de données de l'échantillonnage rend difficile le fait de fournir une évaluation explicite de la fiabilité. L'expansion polynôme du chaos est présentée et discutée. Le modèle de Kriging comme un modèle de substitution joue un rôle important dans l'analyse de la fiabilité. Les méthodes traditionnelles d'optimisation ont des inconvénients à cause du temps de calcul trop long ou de tomber dans un minimum local causant une convergence prématurée. Le recuit simulé est une méthode heuristique basée sur une recherche locale, les Algorithmes Génétiques puisent leur inspiration dans les principes et les mécanismes de la sélection naturelle, qui nous rendent capables d'échapper aux pièges des optimums locaux. Dans l'optimisation de la conception de base de la fiabilité, ces deux méthodes ont été mises en place comme procédure d'optimisation. La boucle de l'analyse de fiabilité est testée sur le modèle de substitution.

Tremendous struggles of researchers in the field of aerodynamic design and aircraft production were made to improve wing airfoil by optimization techniques. The development of computational fluid dynamic (CFD) in computer simulation cuts the expense of aerodynamic experiment while provides convincing results to simulate complicated situation of aircraft. In our work, we chose a special and important part of aircraft, namely, the structure of wing.Reliability based optimization is one of the most appropriate methods for structural design under uncertainties. It struggles to seek for the best compromise between cost and safety while considering system…

▼ El objetivo de este trabajo de tesis consiste en utilizar diferentes modelos de kriging en la simulación condicional de leyes para casos donde la ley media (denominada deriva ) varía en el espacio, lo cual generalmente ocurre en la realidad. Con esto se pretende probar la eficiencia de simulaciones con kriging ordinario (KO) y universal (KU) que consideran la ley media variable en el espacio, con los métodos usados hoy en día basados en kriging simple (KS) suponiendo una ley media constante a escala global. Además se busca analizar el efecto que tiene en los resultados el tipo de algoritmo de simulación utilizado. Para esto, distintos modelos de simulación son aplicados a casos sintéticos y a un caso real de estudio. Para los casos sintéticos se crean diferentes escenarios (con y sin deriva, con muchos y pocos datos condicionantes) y se realizan simulaciones condicionales usando el algoritmo de bandas rotantes y el algoritmo secuencial Gaussiano. El caso real de estudio consiste en un yacimiento de hierro donde existe una clara presencia de derivas de la ley de hierro en la dirección vertical para dos unidades geológicas definidas. Para ambos casos (sintéticos y reales) se evalúan diferentes tipos de condicionamiento. Los resultados se analizan considerando la reproducción de la correlación espacial y de las derivas. Para los casos sintéticos los resultados muestran que, independiente del tipo kriging utilizado, el método secuencial reproduce la correlación espacial cuando hay muchos datos condicionantes. Sin embargo, al usar el método secuencial con KO o KU y pocos datos los resultados se deterioran debido a que el error cometido al usar una vecindad móvil se propaga. El método de bandas rotantes funciona bien independiente del número de datos utilizados. Para casos con derivas, los resultados son mejores con KU, debido a que se conoce perfectamente la deriva. El KS y KO suavizan la deriva, más aun cuando es marcada y se tienen pocos datos condicionantes. Para el caso real ambos algoritmos de simulación entregan buenos resultados, siendo mejores con el algoritmo secuencial Respecto al tipo de kriging, en situaciones de extrapolación el KU exagera la deriva. Así el uso de KU estaría limitado a casos con deriva en situaciones de interpolación donde presenta mejoras respecto al KS y KO. Cuando hay muchos datos condicionantes, se pueden usar ambos algoritmos pues entregan resultados parecidos. Sin embargo, cuando hay pocos datos, el método secuencial propaga el error, por lo que convendría usar el método de bandas rotantes. Además, queda en evidencia la mejora que trae usar KO o KU en las simulaciones para casos con deriva, por sobre el KS utilizado hoy de la industria, el que no refleja lo que ocurre a escala local. Estos enfoques son fáciles de implementar y reflejan mejor las propiedades locales de la variable a simular que el enfoque actual basado en KS. Así, la metodología propuesta podría ser usada en otros casos con características similares, como yacimientos con clara existencia de derivas. Advisors/Committee Members: Emery, Xavier (advisor).
