description: This thesis examines the efforts that the North Atlantic Treaty Organization (NATO) has taken regarding the standardization of rifles and small arms ammunition from the Cold War to the present day and the limitations of these standardization efforts. During the Cold War, NATO was unsuccessful at standardizing a common rifle and its member states only agreed to standardize ammunition calibers. This thesis will discuss the factors that prevented all of the alliance’s militaries from adopting the same rifle models and the problems associated with NATO’s ammunition standardization efforts. Many NATO members intend on procuring new small arms during the 2020s period but there are no plans for the adoption of a common NATO rifle. In the absence of a common rifle for the future, NATO needs to undertake efforts that would both modernize its small arms capabilities and improve the degree of standardization within the alliance.

description: We present a study of the multi-wavelength properties, from the mid-infrared to the hard X-rays, of a sample of 255 spectroscopically identified X-ray selected Type-2 AGN from the XMM-COSMOS survey. Most of them are obscured the X-ray absorbing column density is determined by either X-ray spectral analyses (for the 45% of the sample), or from hardness ratios. Spectral Energy Distributions (SEDs) are computed for all sources in the sample. The average SEDs in the optical band is dominated by the host-galaxy light, especially at low X-ray luminosities and redshifts. There is also a trend between X-ray and mid-infrared luminosity: the AGN contribution in the infrared is higher at higher X-ray luminosities. We calculate bolometric luminosities, bolometric corrections, stellar masses and star formation rates (SFRs) for these sources using a multi-component modeling to properly disentangle the emission associated to stellar light from that due to black hole accretion. For 90% of the sample we also have the morphological classifications obtained with an upgraded version of the Zurich Estimator of Structural Types (ZEST+). We find that on average Type-2 AGN have lower bolometric corrections than Type-1 AGN. Moreover, we confirm that the morphologies of AGN host-galaxies indicate that there is a preference for these Type-2 AGN to be hosted in bulge-dominated galaxies with stellar masses greater than 10^10 solar masses.

description: Due to the global warming, a significant reduction in the emission of greenhouse gases is necessary. One part of the solution is the electrification of today's transportation and traffic sector. An essential component of today's electric vehicles is the lithium-ion battery (LIB), which is largely responsible for their range, performance and cost. In order to increase the use of such climate-friendly technologies, it is therefore essential to reduce the production costs of LIBs. With a duration of up to three weeks, the process steps of formation and aging are particularly capital-intensive and have high demands on storage capacities. Formation and aging therefore account for up to 30% of the manufacturing costs for battery cells. During formation, the solid electrolyte interphase (SEI) is formed, which has a major influence on the quality and lifetime of the LIB, among other things. In order to reduce production costs and simultaneously increase battery cell quality, it is therefore necessary to optimize the formation and aging process. Because of the complexity and the interdependency of these processes towards previous process parameters the application of machine learning algorithm is predestined to optimize these process steps. For this purpose, a general approach for the application of a machine learning algorithm in the formation and aging are first analysed and relevant parameters from the literature as well as reasonable assumptions about the structure are derived. Based on these requirements and boundary conditions a machine learning algorithm structure will be developed to optimize the cell finishing process in the battery cell production.

Performance-based functional tests for the evaluation of daily living activities demonstrate strong psychometric properties and solve many of the limitations associated with self- and informant-report questionnaires. Virtual reality (VR) technology, which has gained interest as an effective medium for administering interventions in the context of healthcare, has the potential to minimize the time-demands associated with the administration and scoring of performance-based assessments. To date, efforts to develop VR systems for assessment of everyday function in older adults generally have relied on non-immersive systems. The aim of the present study was to evaluate the feasibility of an immersive VR environment for the assessment of everyday function in older adults. We present a detailed case report of an elderly woman who performed an everyday activity in an immersive VR context (Virtual Reality Action Test) with two different types of interaction devices (controller vs. sensor). VR performance was compared to performance of the same task with real objects outside of the VR system (Real Action Test). Comparisons were made on several dimensions, including (1) quality of task performance (e.g., order of task steps, errors, use and speed of hand movements); (2) subjective impression (e.g., attitudes), and (3) physiological markers of stress. Subjective impressions of performance with the different controllers also were compared for presence, cybersickness, and usability. Results showed that the participant was capable of using controllers and sensors to manipulate objects in a purposeful and goal-directed manner in the immersive VR paradigm. She performed the everyday task similarly across all conditions. She reported no cybersickness and even indicated that interactions in the VR environment were pleasant and relaxing. Thus, immersive VR is a feasible approach for function assessment even with older adults who might have very limited computer experience, no prior VR exposure, average educational experiences, and mild cognitive difficulties. Because of inherent limitations of single case reports (e.g., unknown generalizability, potential practice effects, etc.), group studies are needed to establish the full psychometric properties of the Virtual Reality Action Test.
R-Parity violating flavor symmetries, recent neutrino data and absolute neutrino mass scale

description: We study the role of a very general type of flavor symmetry in controlling the strength of R-parity violation in supersymmetric models. We assume that only leptons are charged under a global symmetry whose breaking induces lepton number (and, hence, R-parity) violation. The charge assignments of leptons under this symmetry are such that the total number of independent lepton number violating couplings is reduced from 39 to 6. The most severe constraints on these flavor-correlated couplings arise from neutrino masses and mixing as well as from the non-observation of K_L -> eμ. We find that such a scenario predicts an almost vanishing smallest neutrino mass eigenvalue, allowing the upcoming generation of neutrinoless double beta decay experiments to shed light on the hierarchy.

description: © 2020 The Authors. Human Brain Mapping published by Wiley Periodicals, Inc. Detection of the relevant brain regions for characterizing the distinction between cognitive conditions is one of the most sought after objectives in neuroimaging research. A popular approach for achieving this goal is the multivariate pattern analysis which is currently conducted through a number of approaches such as the popular searchlight procedure. This is due to several advantages such as being automatic and flexible with regards to size of the search region. However, these approaches suffer from a number of limitations which can lead to misidentification of truly informative regions which in turn results in imprecise information maps. These limitations mainly stem from several factors such as the fact that the information value of the search spheres are assigned to the voxel at the center of them (in case of searchlight), the requirement for manual tuning of parameters such as searchlight radius and shape, and high complexity and low interpretability in commonly used machine learning-based approaches. Other drawbacks include overlooking the structure and interactions within the regions, and the disadvantages of using certain regularization techniques in analysis of datasets with characteristics of common functional magnetic resonance imaging data. In this article, we propose a fully data-driven maximum relevance minimum redundancy search algorithm for detecting precise information value of the clusters within brain regions while alleviating the above-mentioned limitations. Moreover, in order to make the proposed method faster, we propose an efficient algorithmic implementation. We evaluate and compare the proposed algorithm with the searchlight procedure as well as least absolute shrinkage and selection operator regularization-based mapping approach using both real and synthetic datasets. The analysis results of the proposed approach demonstrate higher information detection precision and map specificity compared to the benchmark approaches.

description: The bound state and low-energy scattering properties of two oriented dipoles are investigated for both bosonic and fermionic symmetries. Interestingly, a universal scaling emerges for the expectation value of the angular momentum for deeply-bound two-dipole states. This scaling traces to the pendulum motion of two dipoles in strong dipole regime. The low-energy scattering phase shifts of two dipoles also show universal behavior. These universal observations make connections to the scaling laws reported in Refs. [1, 2] for three dipoles. Atomic units are used throughout this work.

description: © 2020, The Author(s). There are numerous studies highlighting the impacts of direct and indirect stressors on marine organisms, and multi-stressor studies of their combined effects are an increasing focus of experimental work. Lophelia pertusa is a framework-forming cold-water coral that supports numerous ecosystem services in the deep ocean. These corals are threatened by increasing anthropogenic impacts to the deep-sea, such as global ocean change and hydrocarbon extraction. This study implemented two sets of experiments to assess the effects of future conditions (temperature: 8 °C and 12 °C, pH: 7.9 and 7.6) and hydrocarbon exposure (oil, dispersant, oil + dispersant combined) on coral health. Phenotypic response was assessed through three independent observations of diagnostic characteristics that were combined into an average health rating at four points during exposure and recovery. In both experiments, regardless of environmental condition, average health significantly declined during 24-hour exposure to dispersant alone but was not significantly altered in the other treatments. In the early recovery stage (24 hours), polyp health returned to the pre-exposure health state under ambient temperature in all treatments. However, increased temperature resulted in a delay in recovery (72 hours) from dispersant exposure. These experiments provide evidence that global ocean change can affect the resilience of corals to environmental stressors and that exposure to chemical dispersants may pose a greater threat than oil itself.

This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Postpartum care is a critical element for ensuring survival and health of mothers and newborns but is often inadequate in low- and middle-income countries due to barriers to access and resource constraints. Newly delivered mothers and their families often rely on traditional forms of postnatal care rooted in social and cultural customs or may blend modern and traditional forms of care. This ethnographic study sought to explore use of biomedical and traditional forms of postnatal care. Data were collected through unstructured observation and in-depth interviews with 15 mothers. Participants reported embracing traditional understandings of health and illness in the post-partum period centered on heating the body through diet, steaming, and other applications of heat, yet also seeking injections from private health care providers. Thematic analysis explored concepts related to transitioning forms of postnatal care, valuing of care through different lenses, and diverse sources of advice on postnatal care. Mothers also described concurrent use of both traditional medicine and biomedical postnatal care, and the importance of adhering to cultural traditions of postnatal care for future health. Maternal and newborn health are closely associated with postnatal care, so ensuring culturally appropriate and high-quality care must be an important priority for stakeholders including understand health practices that are evolving to include injections.

description: We present BLOBCAT, new source extraction software that utilises the flood fill algorithm to detect and catalogue blobs, or islands of pixels representing sources, in two-dimensional astronomical images. The software is designed to process radio-wavelength images of both Stokes I intensity and linear polarization, the latter formed through the quadrature sum of Stokes Q and U intensities or as a byproduct of rotation measure synthesis. We discuss an objective, automated method by which estimates of position-dependent background root-mean-square noise may be obtained and incorporated into BLOBCAT's analysis. We derive and implement within BLOBCAT corrections for two systematic biases to enable the flood fill algorithm to accurately measure flux densities for Gaussian sources. We discuss the treatment of non-Gaussian sources in light of these corrections. We perform simulations to validate the flux density and positional measurement performance of BLOBCAT, and we benchmark the results against those of a standard Gaussian fitting task. We demonstrate that BLOBCAT exhibits accurate measurement performance in total intensity and, in particular, linear polarization. BLOBCAT is particularly suited to the analysis of large survey data. The BLOBCAT software, supplemented with test data to illustrate its use, is available at: http://blobcat.sourceforge.net/ .

description: © 2020 authors. Published by the American Physical Society. We determine the strange electromagnetic form factors of the nucleon within the lattice formulation of quantum chromodynamics using simulations that include light, strange and charm quarks in the sea all tuned to their physical mass values. We employ state-of-the-art techniques to accurately extract the form factors for values of the momentum transfer square up to 0.8 GeV2. We find that both the electric and magnetic form factors are statistically nonzero. We obtain for the strange magnetic moment μs=-0.017(4)(0+1)(0+5), the strange magnetic radius rM2 =-0.015(9)(0+3)(0+4) fm2, and the strange charge radius rE2 =-0.0048(6)(-80)(0+12) fm2, where the first error is statistical, and the second and third systematic.

description: With an accelerating rate of data generation, sophisticated techniques are essential to meet scalability requirements. One of the promising avenues for handling large datasets is distributed storage and processing. Hadoop is a well-known framework for distributed storage and processing. Further, data summarization is a useful concept for managing large datasets. Data summarization techniques are intended to produce compact yet representative summaries for the entire dataset. Consolidation of these tools can allow a distributed implementation of data summarization. In this thesis, this goal is achieved by proposing and implementing a distributed Gaussian Mixture Model Summarization using the MapReduce framework (MR-SGMM). The main purpose of the proposed method is to summarize a dataset with a density-based clustering algorithm called DBSCAN algorithm, and then summarize each discovered cluster using the SGMM approach in a distributed manner. Testing the implementation with synthetic and real datasets is used to demonstrate its validity and efficiency.

description: In this thesis work, we study the dynamic pricing strategy (DPS) for different cases and its influences on supply chain coordination. First, we study a DPS for a one-of-a-kind production (OKP) firm with two classes of orders (due-date guaranteed and due-date unguaranteed). We model the DPS using Bellman equation and compare it with a static pricing strategy (SPS). Second, we study the pricing problem for a third-party-logistics (3PL) provider that provides warehousing and less-than-truckload (LTL) transportation services. We develop a stochastic-nonlinear-programming (SNLP) model which computes the optimal freight rates for different delivery dates incorporating the 3PL provider's current holding cost and available transportation capacity. We develop an adjusted multinomial logit (MNL) function to predict customer choices so that our SNLP model can obtain near optimal freight rate settings. Finally, we study dynamic pricing based on a practical OKP firm which is currently employing a SPS. For the three cases, we show the increase of the price-setting firm's profit, customer and social welfare when DPS is employed through simulation, and consequently show the DPS's influence on the performance of the supply chain. We also develop a scheduling method for a manufacturer whose suppliers offer different delivery times at different prices. We abstract the problem to a one-machine scheduling problem which is featured by: (a) the release date of each job is compressible and stochastic, (b) each job has to be delivered before its due date (deadline) and (c) the manufacturer can expedite the production with costly overtime. The target is to minimize the total cost including the compressing cost and the overtime production cost. We coin a concept of a job's late-release-impact factor (LRIF) and we propose a LRIF based heuristic algorithm. Through the numerical test, we shows that the LRIF based algorithm can obtain a better schedule comparing to the ones that are commonly used in practice. By this thesis work, we are trying to integrate an OKP supply chain, which is critical to reduce the cost of OKP companies.

description: © 2020 by the authors. This study demonstrates that monodisperse entangled polymer melts crystallize via the formation of nanoscale nascent polymer crystals (i.e., nuclei) that exhibit substantial variability in terms of their constituent crystalline polymer chain segments (stems). More specifically, large-scale coarse-grain molecular simulations are used to quantify the evolution of stem length distributions and their properties during the formation of polymer nuclei in supercooled prototypical polyethylene melts. Stems can adopt a range of lengths within an individual nucleus (e.g., ~1-10 nm) while two nuclei of comparable size can have markedly different stem distributions. As such, the attainment of chemically monodisperse polymer specimens is not sufficient to achieve physical uniformity and consistency. Furthermore, stem length distributions and their evolution indicate that polymer crystal nucleation (i.e., the initial emergence of a nascent crystal) is phenomenologically distinct from crystal growth. These results highlight that the tailoring of polymeric materials requires strategies for controlling polymer crystal nucleation and growth at the nanoscale.
Balancing Energy Consumption and Average End-to-End Delay for Optimum Routing Protocol in Wireless Sensor Networks

description: Wireless Sensor Networks (WSN) have a power source limitation constraint, which affects the full functionality of its nodes. Existing research focuses on extending the lifetime of the network or minimizing its delay. Energy and delay are introduced into a cost function to optimize the data delivery to the sink. The optimization process becomes more complicated when the network size is increased. A practical routing algorithm is needed to match node capacity and achieve near-optimal lifetime and acceptable delay limits. Angular Directional Routing (ADR) is implemented. ADR routes data based on angles between nodes and the direct path to the destination. Simulations show that ADR outperforms other well-known routing protocols, in terms of average end-to-end delay and energy-efficiency. ADR has the potential to increase network lifetime more effectively than Ad-hoc On-Demand Distance Vector (AODV) protocol. ADR achieves a lower delay compared to Flow Augmentation Routing (FAR).

description: The cystic fibrosis (CF) lung microbiome is a complex polymicrobial community with numerous organisms involved in disease progression. The non-pyogenic streptococci, such as the Streptococcus milleri group, have been implicated in CF disease progression and pathogenesis, but other members are less understood as there has been limited study. The objectives of this study were to characterize a collection of diverse non-pyogenic streptococci and investigate their pathogenic potential and interactions with principal CF pathogens. Genotypic analysis fully characterized 100 unique isolates from CF sputum that did not identify with known species of streptococci by partial 16S rRNA sequencing. To examine these unique isolates, I did extensive genotypic characterization with cpn60, sodA, rpoB and ddl in addition to full 16S rRNA sequencing. 48 isolates identified as novel streptococci isolates, of which 20 of the novel presented with divergent multiple 16S rRNA gene sequences. Phenotypic characterization was expanded to a larger collection of 297 non-pyogenic streptococci isolates with profiling done by several assays. I observed poor correlation between genotypic methods and there was high phenotypic heterogeneity, particularly with regards to increased β-hemolysis under anaerobic condition on human blood as compared to standard conditions. Due to chronic antibiotic use by CF patients, the assessment of the streptococci antibiotic resistome from 459 isolates was done against nine antibiotics relevant in CF treatment. High antibiotic resistance was observed against the macrolides azithromycin (56.4%) and erythromycin (51.6%). Investigation of the molecular mechanisms of macrolide resistance yielded an unexpected result in that nearly half the isolates were found to have point mutations at position 2058 or 2059 of the 23S ribosomal subunit, an uncommon molecular mechanism of resistance within the streptococci. The synergistic interactions of the oropharyngeal flora (OF) with P. aeruginosa were investigated with the construction of transposon mutant libraries in two of the synergen isolates. Mutants were obtained that displayed attenuation or up-regulation of these synergistic interactions and will be used for further study and identification. The work presented here provides the framework to elucidate the role of the diverse streptococci in CF disease progression.

description: To this day, legal statelessness is surprisingly undertheorised in political theory. While there has recently been a resurgence of scholarship on the topic, no one has yet offered a formal typology of statelessness. This dissertation attempts to offer a formal typology. In international law, stateless people fall under two general categories. They are either de facto or de jure stateless – that much is recognised. The first, second, and third chapter of this dissertation interrogate the status quo legal framework by assessing international agreements and the proposals that relevant experts have made for reform. Chapters four, five, six, and seven then examine how stateless people have been treated, at different times and in different places, by governments and the courts around the world. Based on various examples I argue that there are significantly distinct types of statelessness. They are individual statelessness and collective statelessness, as well as three subtypes: voluntary, structural, and denigrative statelessness. These subtypes derive from three distinct sources of nationality deprivation: for voluntary statelessness individuals themselves, for structural statelessness international law, and for denigrative statelessness the country of origin. Having established this typology, I go on to contend that the rights owed to stateless people differ depending on the type of statelessness they suffer from.

description: © 2020 authors. Published by the American Physical Society. We present results for the moments of nucleon isovector vector and axial generalized parton distribution functions computed within lattice QCD. Three ensembles of maximally twisted mass clover-improved fermions simulated with a physical value of the pion mass are analyzed. Two of these ensembles are generated using two degenerate light quarks. A third ensemble is used having, in addition to the light quarks, strange and charm quarks in the sea. A careful analysis of the convergence to the ground state is carried out that is shown to be essential for extracting the correct nucleon matrix elements. This allows a controlled determination of the unpolarized, helicity, and tensor second Mellin moments. The vector and axial-vector generalized form factors are also computed as a function of the momentum transfer square up to about 1 GeV2. The three ensembles allow us to check for unquenching effects and to assess lattice finite volume effects.

description: For the last four hundred years, since the publication of the two parts of El ingenioso hidalgo don Quijote de la Mancha, the representation and perception of the main characters of Cervantes’ novel, i. e., Don Quixote and Sancho Panza, have undergone a process of constant stereotyping by readers and critics. The first images that come to mind at the mere mention of their names are those of an avid book reader a tilter of windmills; and also that of an illiterate, humble, and simpleton peasant. Most scholars have polarized their personalities, representing them as opposites in a dualistic relationship, adding fodder, along the way, to the false dichotomy between orality and literacy. Contrary to this opinion, this research proposes a more human and ethical consideration of all the characters regardless of their origin, social and economic status, or level of education. Starting with the approximation of a working definition of the key concepts of orality and literacy, one of the objectives of this thesis is to indicate how a prejudice against the oral elements of language developed over centuries imposing an intense dichotomism on literary criticism which in time affected Cervantes’ studies. Taking into consideration the various conceptions of critics and scholars of orality and literacy, we will suggest an ampler model of interaction and symbiosis between these abstract traits of language. Assuming that the poetic goal of Miguel de Cervantes was that of verisimilitude, i. e., to imitate the actions and customs of Renaissance individuals in their everyday life, the novel is taken as an historic record valuable for sociolinguistic research and as the basic text for this project. Using the existing state of affairs in the Iberian Peninsula at the turn of the XVI century, as described in literary texts written during this period, this thesis focuses on the evidences of a conspicuous and ubiquitous orality.

description: Large variety of optical full-field measurement techniques are being developed and applied to solve mechanical problems. Since each technique possess its own merits, it is important to know the capabilities and limitations of such techniques. Among these optical full-field methods, interferometry techniques take an important place. They are based on illumination with coherent light (laser). In shearing interferometry the difference of the out of-plane displacement in two neighboring object points is directly measured. Since object displacement does not result in interferometry fringes, the method is suited for localization of strain concentrations and is indeed used in industry for this purpose. Used quantitatively DSPSI possesses the advantage over conventional out-of-plane displacement-sensitive interferometry that only a single difference of the unwrapped phase map is required to obtain flexural strains, thereby relieving problems with noise and reduction in the field of view. The first publication on (DSPSI) was made in 1973, but the emergence of a system providing quantitative measurements is more recent. This work aims to present the results of strain measurements using digital speckle pattern shearing interferometry (DSPSI).

description: It has long been speculated whether the presence of a cilioretinal artery (CRA) can influence the development of glaucomatous damage in patients with open-angle glaucoma. Studies involving healthy patients have shown a change in flow density (FD) depending on the presence of a CRA. Similarly, studies that compared the optical coherence tomography angiography (OCTA) results of healthy controls and glaucoma cohorts identified a reduction in FD in certain retinal layers for glaucoma patients. These observations raise the question of whether FD is altered in glaucoma patients depending on the presence of CRA, with possible implications for the progression of glaucomatous damage. In this prospective study, 201 eyes of 134 primary and secondary open-angle glaucoma patients who visited the Department of Ophthalmology at the University of Muenster Medical Center, Germany were included. The patients were allocated to different groups according to the presence of CRAs and the level of glaucoma severity. The FD results obtained using OCTA for the CRA and non-CRA groups were compared. While FD differed noticeably between the CRA and non-CRA cohorts in the deep macular plexus, no differences in FD were observed between the two groups when adjusted for glaucoma severity. In both the CRA and non-CRA eyes, increasing glaucoma severity correlated most strongly with a reduction in peripapillary FD. Our results suggest that the presence of CRAs does not significantly affect retinal perfusion in glaucoma patients.

Changes in the United States federal-level political landscape have been felt within immigrant communities, and the public health clinics that serve them. We sought to document how HIV prevention and care clinics are reaching and retaining their immigrant community patients during a period of retrenchment of accessible public resources and immigrant rights. From May 2018 through January 2019, we conducted 20 in-depth interviews with clinicians, case workers, advocates, legal experts, and peer navigators in Northern and Central California. Interviews were recorded and transcribed. Several themes emerged which can be grouped into three primary areas: changes post-election, challenges meeting the needs of patients, and best practices for maintaining access to prevention and care services. Post-election, providers reported some of their patients skipping clinic appointments due to fear of Immigration and Customs Enforcement (ICE) raids and deportation while other patients had moved to locations that they felt were less policed. Challenges emerged around linguistic competency, meeting basic needs such as housing stability and employment, and treating mental health sequelae resulting from trauma experienced in home countries or during migration itself. Best practices included hiring bi-lingual and bi-cultural staff, linking to legal services to assist with immigration status, holding trainings around immigrant rights and responses to ICE raids, and building trust with immigrant patients by assuring them that their status would not be collected or reported. In light of adverse policy changes affecting immigrants, agencies have begun to institute best practices to mitigate the negative impact of those policies on their clients and patients.

description: This study investigates the evolutions of microstructure and performance of TiNbZrTaHf-based alloys from equiatomic high-entropy alloys to Ti-rich dilute alloys. A novel biocompatible alloy, Ti50Nb12.5Zr12.5Ta12.5Hf12.5, was developed with a high yield strength of 839 ± 12 MPa, low modulus of 61.5 GPa, low magnetic susceptibility of ∼1.99 × 10−6 cm3g−1, and unprecedented tensile plasticity of 28.7 ± 2.2%. The study discusses the underlying mechanisms responsible for these superior performances, attributing the exceptional plasticity to the activation of cross-slip dislocations, enhanced dynamic recovery and high resistance to crack propagation. The findings provide new insights into the development of biomedical titanium alloys. This study introduces a novel biocompatible concentrated alloy with high strength, low modulus and unprecedented ductility, providing new insights for developing high-performance biomedical titanium alloys.

description: Floods and droughts are key factors in the distribution of vegetation in large rivers. The topographic position in the floodplain is a synthetic indicator of habitat, because along the evolution of river, vegetation adjusted its distribution and abundance to floods and droughts. The amplitude of distribution in the topographic gradient is an indicator of tree resilience to hydrological variability. We postulate that each species has an eco-hydrological signature. We analyze the composition and distribution of the trees in a stretch of 180 Km in Alto Paraná (Argentina), downstream of the Yacyretá dam where we found significant differences in the hydrological regime when comparing the hydrograph before and after Yacyretá. We compared two surveys of vegetation: one before to the reservoir, in 1980 and another in 2014, twenty years after building of Yacyretá, using as an indicator the trees frequency curves, in the same places, with the same method. We were able to establish the response of the river vegetation to the alteration of the regime produced by the reservoir. Our results indicate that 20 years after Yacyretá, there were significant changes in the occurrence of species at each site and between sites at both ends of the study area. Disturbances in the pulse regime cause a new equilibrium in the landscape, in which some tree species are favored and others excluded. Engineering work that disturb the hydrological dynamics of large rivers can alter the distribution of riparian forests. In the same way, changes in vegetation are indicators of disturbances in hydrological dynamics, geomorphology and landscape functioning.

description: This work investigates techniques for building fault-tolerant digital circuits at the nano-scale. It provides an overview of some nano-scale technology candidates that can be used in the next generation of digital circuit based on nanoelectronic logic fabrics. It focuses on fault tolerance of such circuits at both the circuit and the architecture level. A case study based on pass-transistor logic using wrap-gate nanowire devices is presented. Such circuits implement logic computing in the form of binary decision diagrams (BDDs), however, they are not fault-immune. In this thesis, the BDD based nanowire devices that incorporate error correction coding are proposed. In addition, a planarization algorithm is presented and implemented in order to synthesize planar error correcting circuits using such devices. Alternative architecture, such as the cross-bar nano-FPGA, is considered as another candidate for fault-tolerance. Simulation and modeling of all the presented architectures are performed using the developed software "BDD processing tool", CUDD package and SPICE.
