▼ In this dissertation, we develop models and methodologies for effective design and efficient operation of product recovery logistics networks. Recovery networks, employed for recycle-reuse-refurbish-remanufacture purposes, constitute an ever-expanding portion of supply chain networks. For such activities to make business-sense, it is important that the logistical decisions associated with designing and operating underlying networks are made carefully. With this main motivation, we focus on two fundamental problems. First, we consider a generic Closed-Loop Supply Chain (CLSC) network setting under demand and return uncertainty and provide a new model and an efficient solution approach for the associated network design problem. Consideration of uncertainties and their impact on the CLSC network design is a largely ignored area in the literature, thus, this work contributes to closing this gap, in both modeling and solution methodology contexts, as well as in analysis. Second, we consider the specific case of commercial returns, which is quite common in today's business climate, given the generous return policies provided by electronics and department stores as well as retail superstores. In this setting, for operational efficiency and financial effectiveness, it is important for providers to best determine appropriate return channels, i.e., the return channel selection, for commercial products whose values decrease over time. Return channel selection for commercial products is also a largely ignored area in the literature. We first address this problem from an operational efficiency perspective given an underlying network of facilities. In the related models and analysis, we introduce and capture the concepts of channel selection dependence on product and logistics network characteristics. Later, recognizing that the design of an underlying network may be under the control of the provider, we take an integrated design and operation perspective and incorporate the logistics network design into the model to further study dependence of channel selection on network characteristics. In addition to new models and analysis for commercial return logistics, our contributions also include the development of efficient solution algorithms with measurable solution quality. We introduce the problems of interest and their context in today's business environment in the first chapter. In the second chapter of the dissertation, we develop a two-stage stochastic programming model for the generic CLSC network design problem under demand and return uncertainty, represented by a set of scenarios. For the model's solution, we develop a Benders Decomposition (BD) approach that significantly improves computational efficiency via surrogate constraints, strengthened Benders cuts, multiple Benders cuts, and mean value scenario based lower bounding inequalities. In the third chapter, we develop models for the channel selection problem for commercial products under time-value consideration. Based on this model, we analyze the optimal return… Advisors/Committee Members: Uster, Halit (advisor), Curry, Guy (advisor), Cetinkaya, Sila (committee member), Ketzenberg, Michael (committee member).

▼ In this thesis we present a monolithic coupling approach for the simulation of phenomena involving interacting fluid and structure using different discretizations for the subproblems. For many applications in fluid dynamics, the Finite Volume method is the first choice in simulation science. Likewise, for the simulation of structural mechanics the Finite Element method is one of the most, if not the most, popular discretization method. However, despite the advantages of these discretizations in their respective application domains, monolithic coupling schemes have so far been restricted to a single discretization for both subproblems. We present a fluid structure coupling scheme based on a mixed Finite Volume/Finite Element method that combines the benefits of these discretizations. An important challenge in coupling fluid and structure is the transfer of forces and velocities at the fluidstructure interface in a stable and efficient way. In our approach this is achieved by means of a fully implicit formulation, i.e., the transfer of forces and displacements is carried out in a common set of equations for fluid and structure. We assemble the two different discretizations for the fluid and structure subproblems as well as the coupling conditions for forces and displacements into a single large algebraic system. Since we simulate real world problems, as a consequence of the complexity of the considered geometries, we end up with algebraic systems with a large number of degrees of freedom. This necessitates the use of parallel solution techniques. Our work covers the design and implementation of the proposed heterogeneous monolithic coupling approach as well as the efficient solution of the arising large nonlinear systems on distributed memory supercomputers. We apply Newton’s method to linearize the fully implicit coupled nonlinear fluid structure interaction problem. The resulting linear system is solved with a Krylov subspace correction method. For the preconditioning of the iterative solver we propose the use of multilevel methods. Specifically, we study a multigrid as well as a two-level restricted additive Schwarz method. We illustrate the performance of our method on a benchmark example and compare the afore mentioned different preconditioning strategies for the parallel solution of the monolithic coupled system.

▼ Warm-season perennial grasses are predominant in Florida livestock production systems, but they rely on N fertilizer to improve diet quality and herbage production. Use of N fertilizer increases greenhouse gases (GHG) emissions and may be limited due to fluctuation of prices compromising stand persistence. Incorporation of legume into forage systems supplies N and minimizes GHG emissions. The objective was to evaluate the effect of year-round N-fertilized grass (GN)- and legume (LG) -based forage systems managed under grazing or hay harvest strategies on nutrient cycling, nitrous oxide (N2O) emissions and soil carbon (N) and nitrogen (N) accumulation. In a litter bag decomposition study, patterns of response of C/N ratio, and N and lignin concentrations were relatively constant throughout the incubation period. On the second year, rainfall patterns favored greater biomass losses, even with lesser initial N concentration and greater ADIN concentration in total N in initial litter. Nitrogen immobilization occurred extensively up to 128-d after incubation, and greater values were associated with GN systems, which reflected in slower N remaining decay rates. Legume systems mineralized up to 50% of total N of GN systems. Greater 30-d cumulative N2O emissions was associated with summer season. The peak of N2O emissions occurred consistently within 20 days after N-fertilizer application, and emission factor (EF) for GN systems were lower than 1%, but this does not account for indirect emissions due to production, storage, and transportation of N fertilizer. In a study using six rhizoma peanut (RP) entries managed under lenient defoliation, short growing canopies were associated with greater root-rhizoma mass and canopy bulk density. Although chosen entries represented a broad range of sward characteristics, there were limited differences on soil responses due to treatment effect. Also, correlations between sward characteristics and soil C and N concentrations and stocks to 20-cm depth were limited, and mostly related to the 10 to 20 cm depth. However, it is unclear if this response was due to lack of existent correlations or because of limited soil responses under this study.

▼ Appalachian mixed hardwood stands along south facing slopes of the Ridge and Valley physiographic province were used to determine fine scale soil respiration (Rs ) and nutrient dynamics among four distinct cover types, white oak (WO, Quercus alba L.), scarlet oak (SO, Quercus coccinea Muech.), chestnut oak (CO, Quercus montana Wild.) and a pine-oak co-dominant cover (PO, Pinus spp. and Quercus spp. (primarily Pinus pungens Lamb. and Q. montana)). Null hypotheses were that: (1) Rs and its relationship to environmental drivers would not differ among the cover types, (2) water and nutrient use efficiencies (WUE and NUE) would not differ among the cover types, and (3) litter decomposition would not differ among the diverse cover types. In 0.02 ha plots, replicated four times, Rs and associated variables (e.g., soil temperature and moisture) were measured. Measurements occurred in three sub-sample locations per plot, from July 2014 - December 2015. In each plot, foliage from two trees of the dominant species were collected to determine WUE using δ¹³C isotope discrimination. Nutrient (N, P and K) content of this fresh foliage was compared with that of litterfall to determine NUE. Litterbags, collected over a one and half year period were used to determine decomposition rate constants for each dominant species. Soil temperature and moisture explained 71% of the variability in Rs. Although only slight, there were statistically significant differences in the Rs models due to cover type. At the same soil temperature, the PO cover type had the highest Rs while the SO, WO cover types had the lowest Rs. WUE, and NUE varied among cover types. SO had significantly greater WUE than the other species, including Table mountain pine, which had the highest NUE. Higher elevation cover types (i.e., PO and CO) ad greater decomposition rate constants. Among the factors driving decomposition, soil C: N ratio had the strongest correlation to decomposition. Correlations between decomposition and productivity variables of total above ground biomass, total stand biomass, and aboveground net primary production also exist. In conclusion, carbon and nutrient cycling varies across the level of cover type within the southern Appalachian hardwood forests. Future efforts to focus on carbon and nutrient dynamics in the context of land use or global change should consider these finer-scale differences. Advisors/Committee Members: Seiler, John R.

▼ The effects of litter quality and inorganic nitrogen (N) on rate of decomposition and N release pattern by three leguminous woody species were investigated under field conditions by the litterbag technique. The species studied in 1994/1995 were Leucaena leucocephala, Senna siamea and Flemingia macrophylla. This study was superimposed on an existing alley cropping trial. In the on-going experiment , maize (variety MM 603,3-way cross), was the companion crop and the leguminous species comprised the alley hedgerows. Nylon litterbags with 4 mm mesh size were each filled with 20 g of dry leaf prunings of each species. Five litterbags of each pruning type were randomly buried in a subplot of each treatment. At each sampling time, one bag representing each pruning type was removed from each subplot. The samples were cleaned , dried , weighed and analysed for N, polyphenol and lignin contents. Decomposition rate constants (kD) and N release rate constants (kN) were calculated from exponential decomposition equations. The mean(kD) of the plant litter ranged from 0.30 to 0.12wk-1, decreasing in the order , L. leucocephala,>S. siamea> F. macrophylla. Analysis of variance of the mean kD values showed that L. leucocephala, and S. siamea decomposed significantly (P<_0.01) faster than F. macrophylla. It was also observed that the level of inorganic N had a significant effect on decomposition rate. Residues in plots which received 68 and 112 kg N ha-1 had similar decomposition rate which were faster((P<-0.05) than those for 0 and 34 kg N ha-1. Negative partial correlations were recorded between kDs, on one hand and lignin and polyphenol contents(P<-0.01), C:N ratio (P<-0.01) and lignin + polyphenol:N ratio (P<-0.01) and inorganic N level (P<-0.01). These results show that both the chemical composition of plant residues and level of inorganic fertilizer N applied increased the rate of plant residue decomposition. The mean (kN) ranged from 0.151 to 0.114wk-1, decreasing in the order L. leucocephala,>S. siamea> F.macrophylla. There were however , no significant species on N level effects on kN. Generally, net N release was obtained in the first 2-3 weeks followed by immobilization thereafter in all species. Positive partial correlations(P<-0.05)were recorded with initial N- content ( P<-0.05) suggested that it affects decomposition rates. Negative partial correlations were recorded between initial lignin and polyphenol contents and kN. Lignin and polyphenols are thought to have caused N immobilization through the formation of resistant complexes. There was no significant species effect on maize yields . A significant N fertilizer effect on yield was obtained at 68 kg N ha-1. This result probably indicates the need for moderate fertilizer N addition to incorporated residues in alley cropping.

▼ Matrix decomposition plays an increasingly significant role in many scientific and engineering applications. Among numerous techniques, Singular Value Decomposition (SVD) and Eigenvalue Decomposition (EVD) are widely used as factorization tools to perform Principal Component Analysis for dimensionality reduction and pattern recognition in image processing, text mining and wireless communications, while QR Decomposition (QRD) and sparse LU Decomposition (LUD) are employed to solve the dense or sparse linear system of equations in bioinformatics, power system and computer vision. Matrix decompositions are computationally expensive and their sequential implementations often fail to meet the requirements of many time-sensitive applications. The emergence of reconfigurable computing has provided a flexible and low-cost opportunity to pursue high-performance parallel designs, and the use of FPGAs has shown promise in accelerating this class of computation. In this research, we have proposed and implemented several highly parallel FPGA-based architectures to accelerate matrix decompositions and their applications in data mining and signal processing. Specifically, in this dissertation we describe the following contributions: • We propose an efficient FPGA-based double-precision floating-point architecture for EVD, which can efficiently analyze large-scale matrices. • We implement a floating-point Hestenes-Jacobi architecture for SVD, which is capable of analyzing arbitrary sized matrices. • We introduce a novel deeply pipelined reconfigurable architecture for QRD, which can be dynamically configured to perform either Householder transformation or Givens rotation in a manner that takes advantage of the strengths of each. • We design a configurable architecture for sparse LUD that supports both symmetric and asymmetric sparse matrices with arbitrary sparsity patterns. • By further extending the proposed hardware solution for SVD, we parallelize a popular text mining tool-Latent Semantic Indexing with an FPGA-based architecture. • We present a configurable architecture to accelerate Homotopy l1-minimization, in which the modification of the proposed FPGA architecture for sparse LUD is used at its core to parallelize both Cholesky decomposition and rank-1 update. Our experimental results using an FPGA-based acceleration system indicate the efficiency of our proposed novel architectures, with application and dimension-dependent speedups over an optimized software implementation that range from 1.5ÃÂ to 43.6ÃÂ in terms of computation time.

▼ Invasive plant species in natural ecosystems have been shown to have a wide range of potential impacts on community composition and ecosystem function. Alligator weed (Alternanthera philoxeroides) is invasive in New Zealand and elsewhere. An aggressive competitor and difficult to control, its impacts in productive ecosystems are widely documented. However, little information exists about alligator weed???s effects in natural ecosystems. This thesis therefore investigated potential effects of alligator weed on decomposition and nutrient cycling, as well as on invertebrate and plant communities in a ???native??? ecosystem, thus integrating effects on ecosystem processes and community composition. These aspects were compared between vegetation dominated by alligator weed or by one of two native sedges, Isolepis prolifer and Schoenoplectus tabernaemontani, in a northern New Zealand lake. In addition, the potential of shading to control alligator weed was assessed. Herbivory by the biocontrol agent Agasicles hygrophila resulted in substantial alligator weed defoliation, differing in timing and magnitude from biomass dynamics of the native sedges. Alligator weed also decomposed faster than either native sedge. Changes in decomposition dynamics led to a shift towards fungivore dominated beetle communities. This illustrates the potentially complex ecosystem effects of biocontrol agents as well as invasive weeds. Alligator weed decomposition rates and invertebrate communities were more similar to those of I. prolifer than S. tabernaemontani. This pattern was attributed to the greater chemical and architectural similarity of alligator weed to I. prolifer compared with S. tabernaemontani. Invasive plants??? impacts may thus be partially influenced by the degree of similarity between the invasive species and the dominant vegetation they invade. Alligator weed was associated with decreased cover of native plants, potentially placing them at greater risk of local extinction. Greenhouse and field experiments showed that shading significantly reduced alligator weed growth. However, clonal support from unshaded areas, and competitive release from less shade tolerant plants, may potentially impede the success of shade based control. This research demonstrates that alligator weed can have a range of complex and multi-trophic effects in a natural ecosystem. Further, characteristics of both invasive and competing vegetation can influence the success of cultural control methods such as shading.

▼ The relationship between trees and ectomycorrhizal fungi is fundamental for tree growth and survival, particularly in the boreal forests of North America where low temperatures inhibit decomposition and consequently limit nutrient availability. The responses of ectomycorrhizal fungal communities to large-scale disturbances and host phenology are not well known, but are important for restoring and predicting carbon and nutrient cycling. To that end, I investigated the ectomycorrhizal fungal community present on roots of outplanted seedlings in sites that captured a gradient of above and belowground disturbances. Additionally, I monitored the extracellular enzyme secretions of ectomycorrhizal fungi during four phenological stages (host dormancy, leaf flush, full leaf expansion, leaf abscission) of mature Populus tremuloides stands to assess the potential decomposing activity of ectomycorrhizal fungi in relation to changes in tree physiology. Contrary to my prediction, there was no difference in ectomycorrhizal fungal community composition across sites that differed in extent of above and belowground disturbances; composition was instead primarily affected by the species of seedling used to assay the soils. Further, I found relatively constant levels of enzyme secretions by ectomycorrhizas across phenological stages irrespective of the amount of carbon stored in roots, suggesting the enzymes I measured may be secreted to acquire nitrogen or phosphorus locked within organic matter. Additionally, potential enzyme activity was better predicted by the foraging strategy of ectomycorrhizal fungi, highlighting the functional roles of species. These findings emphasize the importance of planting a diverse community of trees in reclaimed soils to yield a diverse community of belowground fungi. Moreover, differences in potential enzyme activity of exploration types throughout phenological stages point to unique functional roles among fungi, which may change seasonally. Consequently, this research stresses the importance of restoring functional diversity in reconstructed ecosystems.

▼ Interest in increasing agroecosystem diversity through use of cover crops continues to rise. Cover crops are non-harvested crops that provide a range of ecosystem functions, and mixtures of cover crop species with complementary traits, such as legumes and grasses, may increase multiple functions at once. However, the performance of cover crops grown in monocultures and mixtures is expected to vary across farms with different levels of soil fertility, which result from unique management histories. Understanding the interactions of these two factors can help optimize the use of cover crops for more sustainable soil nutrient management. This study therefore addressed the following research questions: (1) Do legume-grass cover crop mixtures alter rates of decomposition compared to legume and grass cover crop monocultures? (2) Are the effects of litter type different in soils with different management histories? We incubated three litter treatments in two soils with contrasting fertility levels for 360 days, and measured decomposition dynamics through respired CO2, microbial extracellular enzyme activity, and inorganic N mineralization. As expected, new carbon inputs to soil increased microbial processes in the short term, but basically had no long-term effect on the measured responses. The lower fertility soil had a greater response to litter addition for both CO2 respiration and enzyme activities for enzymes that degrade labile organic carbon compounds. The total inorganic N release was higher on the high fertility soil. Overall, both cover crop litter addition and farm management history affect microbial decomposition dynamics. In this study, we found that cover crop litter addition had a stronger effect on soil biological processes compared to management history, however, the difference between litter mixture and monoculture treatments was not significant.

▼ Sucrose from cane and beet sources is greater than 99.8% pure. However, sucrose from both sources displays different thermal behavior. In their DSC thermal profiles, cane sucrose displays a small endothermic peak (small peak) before the main endothermic peak (large peak), which is not present in beet. The presence of the small peak results in a lower onset temperature for thermal decomposition in cane sucrose, compared to beet. To compare the thermal behavior of these sucrose sources, the kinetic parameters for the thermal decomposition of crystalline cane and beet sucrose were determined herein. Since sucrose thermal decomposition is a complicated process, causing the formation of decomposition products, loss of crystalline structure, and, at sufficiently high temperatures, these events can overlap with true melting, a variety of kinetic methods were used to characterize the thermal behavior of the system. Initially, a nonisothermal kinetic method was used to obtain the kinetic parameters for cane and beet sucrose thermal decomposition. Commercial beet sucrose (US beet) exhibited a higher activation energy (Ea) than either analytical grade (Sigma cane) or commercial cane sucrose (US cane), which displayed similar Ea values. The higher Ea for US beet suggested that thermal decomposition is inhibited in beet sucrose, compared to cane. The nonisothermal method was also used to explore the effect of lot-to-lot variation on the kinetic parameters of Sigma cane to fully characterize the thermal behavior of the material. While there were differences in the thermal behavior parameters for each lot, the kinetic parameters for the small peak were similar for all lots, suggesting that lot-to-lot variation does not lead to differences in the kinetic parameters. Although there were not differences in the small peak kinetic parameters, the use of several lots does provide a better predictor of the variability that can occur when different lots of sucrose are used in a product. Next, isothermal experiments were performed to assess the accuracy of the kinetic parameters obtained from nonisothermal experiments. To compare these experimental conditions, the predicted rate constant (k) and half-life (t1/2) values determined from nonisothermal experiments were compared to those obtained from isothermal experiments at 130°C. Based on the results of the isothermal experiments, the nonisothermal kinetic parameters overestimate k for cane-sourced sucrose, and underestimate k for beet sucrose. To further explore the differences between nonisothermal and isothermal methods, the Ea for sucrose thermal decomposition was determined using the isothermal isoconversional kinetic method, which allows for the Ea to be determined as a function of the extent of the reaction (α). Additionally, the use of isothermal methods allows for the kinetic parameters to be determined without the interference of the overlap of true melting. Under isothermal conditions, US cane displayed the largest Ea value at 2% α, while the Ea values displayed by Sigma cane… Advisors/Committee Members: Schmidt, Shelly J (advisor), Bohn, Dawn M (Committee Chair), Cadwallader, Keith (committee member), Takhar, Pawan S (committee member), Thomas, Leonard C (committee member).

▼ Twin Cays, Belize, is dominated by Rhizophora mangle L. (red mangrove). Tall (>5m in height) R. mangle are located along the fringe of the island and dwarf R. mangle grow in the interior of the island. These stand structures can be differentiated using δ13C and δ15N analysis (mean tall δ13C = -28 ‰, mean tall δ15N = 0‰; mean dwarf δ13C = -25‰, mean dwarf δ15N = -10‰), which may also prove useful in examining past mangrove stand structures from sediment cores. 15N label was traced in R. mangle leaves in a laboratory and field experiment over three months. The 15N label was examined to determine distribution of nitrogen in various biochemical fractions of the leaf and to verify if nitrogen is fractionated in a predictable manner over time. This information could be beneficial in examining past mangrove stand structures. Experimental data indicate that nitrogen is mobile within each biochemical fraction of the R. mangle leaf over time and a measurable amount of nitrogen exists in each fraction after 3 months of incubation. Nitrogen immobilization was evident in each experiment, as the δ15N values decreased ~200‰ in each of the labeled fractions of the laboratory experiment, which was mirrored by an increase in δ15N in the control samples. The amount of nitrogen in the biochemical fractions of the field experiment varied over time either increasing or decreasing, which may be due to the various environmental conditions such as tidal fluctuation, temperature, oxygen concentrations and microbial activity. The δ15N signature of the residual nitrogen fraction (δ15N = 87‰) reflected that of the bulk fraction (δ15N = 133‰) in the laboratory experiment as well as in the field experiment (residual nitrogen δ15N = 759‰, bulk δ15N = 770‰). To use isotope analysis to examine past mangrove stand structures it is essential that the original signature be maintained over time. The results of this study indicated that the simple interpretation of nitrogen isotopes may not be useful in examining past mangrove stand structures due to the variation over time, although this type of analysis may be considered if coupled with additional proxies and diagenetic factors are taken into account.

Research Doctorate - Doctor of Philosophy (PhD)

The development of smart grids, especially the vast deployment of smart meters, enables users to access their energy data on a much more detailed scale. This has promoted considerable interest in nonintrusive load monitoring (NILM) research. It is hoped that NILM techniques can separate energy-consumption data into individual appliance levels, thereby aiding customers who want to save energy or cut back usage. For this dissertation, we implemented a novel NILM system based on a support vector machine (SVM), an edge symbol analysis method (ESA), and principal power component analysis (PPCA). Our research uses a set of power load disaggregation methods, which constitute the most important part of our NILM system. Furthermore, our system automatically monitors a household power consumption and the power consumption of individual devices. We have developed the means to automatically detect a power-load event and the means to classify appliances based on machine learning. Our methods involve a new transient-detection algorithm. By analysing turn-on and turn-off transients, it can accurately detect the points when a device is switched on or switched off. The proposed load classification technique can identify different power appliances with better recognition accuracy and computational speed. The load classification method comprises two items: frequency feature analysis and a support vector machine. Our results indicate that by incorporating the new edge detection and turn-on, turn-off transient signature analyses into our NILM, more information is revealed than by traditional NILM methods. The load classification method achieved more than 90 percent recognition rate. We also propose a multiple class support vector machine to recognize different appliances. The approach consists of two stages. In stage one, feature analysis is applied to power signals. In stage two, a trained classifier based on SVM was applied to identify different appliances. Our experiment results on real data give better performance compared to other studies that have used supervised classification for household power-appliance monitoring. Our contributions also focus on feature extraction and pattern analysis for whole-house power load classification and disaggregation. Specifically, after finding a specific power event (such as a switch-on or switch-off) and clustering data in terms of power factor, the optimized features can be obtained from our algorithm by looking at harmonics of active/reactive power and using eigenvalue feature analysis. The experiments, based on real world data, give higher recognition accuracy and faster computational speed, and represent a promising approach for distinguishing different loads effectively.

▼ In today’s information transfer, multimedia is playing a major role and it has vast and rigorous issues that can be studied. Its nature is widely varied and the objects are characterized in various ways requiring a fully developed multimedia database management system to support the current diverse applications. Most of the operations in multimedia application are data intensive; hence it is advantageous to make use of distributed applications in this regard. Also having a distributed multimedia database is indispensable for the motto “Multimedia Anywhere, Anytime”. A multimedia database management system needs to address complex design issues such as: composition and decomposition of multimedia objects; operations of multimedia objects with media synchronization; security; consistency, atomicity, and concurrent access in a distributed environment; and long transactions and multi-level/nested transactions. To accomplish this level of interaction, an efficient information, communication, and cooperation environment is crucial. In this thesis work, we present mobile agent-based architecture for managing distributed multimedia databases’ multi-level transactions. The case study considers decomposition and composition transactions in media objects uploading and downloading request of a multimedia database. The transactions are studied in three layers: index, data and presentation with the use of concurrent executions of agents in an agent platform middleware. The middleware is designed to run on every node of the distributed system outfitted with standard relational database management system for the binary large objects storage of the multimedia. The performance of the system/architecture is then tested and analyzed for a prototype over distributed computers in the Intranet of the faculty for efficient information distribution and retrieval. Its performance is then compared with a sample legacy application build from the ordinary remote procedure call execution of the multi-level transactions to meet the temporal quality of service requirement of media objects uploading and downloading.

▼ Olefin metathesis is one of the most powerful tools in current use for the assembly of carbon-carbon bonds. The advent of easily-handled ruthenium catalysts, along with new awareness of ring-closing metathesis (RCM), led to widespread adoption of metathesis methodologies in synthetic organic chemistry. Relative robustness to air and water, and tolerance for an impressive range of functional groups, is attested to by the recent appearance of RCM in pharmaceutical manufacturing processes. However, challenges remain, particularly with respect to the ease with which these catalysts undergo loss of the critical Ru=CHR functionality that enables metathesis. This limits not only metathesis productivity, but also selectivity, because the Ru products can promote unwanted C=C migration reactions. Many decomposition pathways have been found to culminate in activation of the N-heterocyclic carbene (NHC; most typically an H2IMes) ligand. In consequence, NHC truncation is a widely accepted design solution. This thesis work was aimed at assessing the validity of this proposition from several perspectives. Hundreds of metathesis catalysts are now known, but the second-generation Grubbs catalyst (GII) is still most widely used. This work began with examining the role of Lewis bases in promoting decomposition of the second-generation Grubbs catalyst, RuCl2(H2IMes)(PCy3)(=CHPh) GII, under conditions of metathesis. Small Lewis donors, ranging from pyridine and DMSO to THF and water, were shown to greatly accelerate loss of the methylidene ([Ru]=CH2) ligand. Associative donor binding was shown to promote dissociation of PCy3, a powerful nucleophile which then attacks at the methylidene carbon. Attempts to probe the reversibility of this step revealed no reformation of the [Ru]=CH2 unit, suggesting that nucleophilic attack to form a [Ru]–CH2PCy3+ moiety is the key decomposition event. Ensuing C-H activation of a ligand (e.g. the o-methyl of H2Mes or IMes), with abstraction of a chloride ligand, results in elimination of [MePCy3]Cl. Two potential preventative measures were examined. These involved, first, the use of phosphine scavengers to intercept the liberated PCy3 ligand during metathesis, and second, truncation of an N-mesityl group to N-methyl to inhibit C-H activation. While phosphine scavenging proved somewhat successful in increasing metathesis yields, lower activity was observed for the catalyst with the modified NHC ligand. The negative impact of a smaller NHC on catalyst activity is of particular interest, given that curtailed NHC bulk has been proposed as the key to improved catalyst robustness, as noted above. ix To clarify this issue, truncation of the nitrogen substituents was taken to the extreme by replacing both N-mesityl groups with N-methyl. Accordingly, the reaction chemistry of the first-generation Grubbs catalyst, RuCl2(PCy3)2(=CHPh) GI with 1,3,4,5-tetramethylimidazol-2-ylidene (IMe4) was explored. The small size of this NHC ligand precludes access to a stable mono-IMe4 catalyst corresponding to GII: rather, an…

▼ Seismic prediction of rock properties from seismic attributes using multiple regression is equivalent to projecting bases functions onto the observed rock-properties; a process that is equivalent to Matching-Pursuit Decomposition. Matching Pursuit is a greedy algorithm that becomes unstable when the bases functions are highly correlated to each other. In this thesis, I investigate the use of Fractional-Matching-Pursuit to stabilize the prediction of rock properties from correlated seismic-attributes and demonstrate the efficacy of the method on an oil field in the Permian Basin. Fractional-Matching-Pursuit Decomposition, as employed here, uses a seismic-attribute dictionary to decompose measured well-logs into a summation of seismic attributes - assigning fractional coefficients to selected attributes from the dictionary - and predicts the desired reservoir-property as the sum of the attributes after weighting by the fractional coefficients. For any iteration step, the algorithm subtracts only a fraction of the variance of the input data that can be correlated to any particular attribute. Thus, small changes in the seismic data do not produce large changes in the attributes used, and the resulting predictions are stabilized. The procedure was applied to a dataset from the Indian Canyon Ranch in the Permian Basin to predict neutron-porosity, gamma-ray, and impedance logs. These predictions were compared to the input well logs with error of estimation in validation wells used as the measurement of success of this experimental methodology. Fractional-Matching-Pursuit predictions were compared to Matching-Pursuit predictions for several log properties and consistently were better. The process is sensitive to the frequency content in the logs, and appeared to be able to exceed the resolution limits of the seismic data, thereby predicting thin layers below the resolution of the original seismic-data.
