Scattering of Seismic Waves from Arbitrary Viscoelastic-Isotropic and Anisotropic Structures with Applications to Data Modelling, FWI Sensitivities and Linearized AVO-AVAz Analysis

description: It is acknowledged that Full Waveform Inversion (FWI) techniques are sensitive to the set of model parameters that we choose for the minimization procedure. This model parametrization and sensitivity analysis for FWI has been extensively studied for acoustic and isotropic-elastic media. In order to obtain an accurate image of subsurface earth, it is necessary to include both anisotropy and attenuation in inversion procedures as subsurface materials are far from being isotropic or elastic. In this thesis, we formulate the sensitivity analysis for FWI in viscoelastic-isotropic/anisotropic media. To develop such analysis, we construct a framework based on the first order perturbation theory called the Born approximation to find the sensitivity of the FWI to isotropic, anelastic and anisotropic parameters. Sensitivities are, essentially, radiation patterns induced by scattering of the seismic waves from inclusions in medium properties in an isotropic background. Most importantly, we investigate the effect of the inhomogeneity angle which is unique to viscoelastic waves, on these radiation patterns (scattering potentials) and also on amplitude-variation-with-offset or azimuth (AVO/AVAz) analysis. By decomposition of the scattering potentials into isotropic, viscoelastic and anisotropic components, we specify the effects of anelasticity, inhomogeneity of wave and anisotropy on radiation patterns and the linearized AVO/AVAz equations. Moreover, we show how the obtained scattering potentials reduce to the linearized AVO/AVAz equations without using the solution of Zoeppritz equations. This analysis is the starting point for any FWI strategy in a complex media exhibiting both attenuation and anisotropy, as the scattering potentials that we obtained can be effectively implemented to choose a suitable model parametrization.
Evaluation of Innovation Strategies to Achieve Process Innovation in the Oil Industry

description: This dissertation includes three essays exploring the development of technical process innovations in the oil industry. Currently, the industry is facing a fast-changing technological environment, calling for innovations addressing its environmental, social and financial challenges. This context is interesting because the study of both the oil industry, as a process- and resource-oriented industry, and of technical process innovations has been lacking in the business literatures. The first essay studied a new entrant to the Canadian oil industry that aimed to develop a disruptive process innovation. By studying this case, I identified some of the challenges that the firm faced through developing the innovation, including a) a lack of resources, b) a vertical leadership style, c) tension between the investors` expectation to gain quick profit and the lengthy process of technology development, and d) internal collaboration. The study suggests that to address these barriers, new entrant firms may: 1) utilize inter-firm collaboration, 2) develop intra-firm collaboration, 3) develop non-vertical leadership skills, and 4) secure long-term investments. The second essay, a multiple case study of innovation intermediaries in the Canadian oil industry, followed the finding of the first essay on collaboration. In this essay, I extended the open innovation model both theoretically and practically by identifying the boundary conditions that motivate firms and the approaches that have been implemented in practice in applying this model. The second essay suggests that institutional forces (e.g., normative and coercive forces) are the primary motivators for adopting open innovation in response to the social and environmental concerns faced by the oil industry. In addition, by building on meta-organizations’ taxonomy, the study demonstrates that establishing not-for-profit innovation intermediaries was necessary to govern adoption of open innovation in this industry. The third essay explored one of the most successful models of such innovation intermediary and discusses its successes and failures. The conceptual model that was derived from the findings combines strategic bridging organisational concepts with open innovation model ideas to help us understand how an innovative technologies network at the industry level is built.

description: In this paper, we construct the index bundle gerbe of a family of self-adjoint Dirac-type operators, refining a construction of Segal. In a special case, we construct a geometric bundle gerbe called the caloron bundle gerbe, which comes with a natural connection and curving, and show that it is isomorphic to the analytically constructed index bundle gerbe. We apply these constructions to certain moduli spaces associated to compact Riemann surfaces, constructing on these moduli spaces, natural bundle gerbes with connection and curving, whose 3-curvature represent Dixmier-Douady classes that are generators of the third de Rham cohomology groups of these moduli spaces.

“It’s not just camp”: Understanding the Meaning of Children’s Cancer Camps for Children and Families

description: In response to the stress of the childhood cancer experience, children’s cancer camps arose in the 1970s as a way for children and their families to escape the rigidity and severity of cancer treatment. Cancer camps are designed to meet the needs of the whole family at each stage in the cancer experience—from diagnosis through treatment, to survival or bereavement. In 2008, the eight camps across Canada provided specialized oncology camps and community support programs to 5,252 children and their families – a 10% increase from the previous three years. As more children are surviving childhood cancer, the need for specialized camps and community programs continues to grow. My purpose in this philosophical hermeneutic inquiry was to understand the meaning of children’s cancer camps for the child with cancer and the family. Six childhood cancer families and five cancer camp counselors were interviewed in order to bring understanding to this topic. Findings from this research revealed that camp means different things for different families, and that much is at play in the cancer camp experience: finding acceptance and fit, grief as something to live with versus “get over,” storytelling as a means of re-shaping and understanding traumatic experiences, and the solidarity of the community as one that creates intense, healing bonds. Children’s cancer camps, I conclude, need to be considered a necessity, versus a luxury, and should even be thought of as a psychosocial intervention for some children and families. Barriers such as structure of funding and access to resources are present, and likely due to the separate-ness of camps from hospital programs. In addition, this research speaks to the need for interpretive methods like hermeneutics to incorporate a tool such as Social Return on Investment, a principles-based approach that values change that would not otherwise be valued, when questions of social value are present.

description: Causal systems often exhibit variations of the underlying causal mechanisms between the variables of the system. Often, these changes are driven by different environments or internal states in which the system operates, and we refer to context variables as those variables that indicate this change in causal mechanisms. An example are the causal relations in soil moisture-temperature interactions and their dependence on soil moisture regimes: Dry soil triggers a dependence of soil moisture on latent heat, while environments with wet soil do not feature such a feedback, making it a context-specific property. Crucially, a regime or context variable such as soil moisture need not be exogenous and can be influenced by the dynamical system variables - precipitation can make a dry soil wet - leading to joint systems with endogenous context variables. In this work we investigate the assumptions for constraint-based causal discovery of context-specific information in systems with endogenous context variables. We show that naive approaches such as learning different regime graphs on masked data, or pooling all data, can lead to uninformative results. We propose an adaptive constraint-based discovery algorithm and give a detailed discussion on the connection to structural causal models, including sufficiency assumptions, which allow to prove the soundness of our algorithm and to interpret the results causally. Numerical experiments demonstrate the performance of the proposed method over alternative baselines, but they also unveil current limitations of our method.

description: We present a systematic study of the field and size dependencies of the static fluxon lattice configuration in Bi-2212 intrinsic Josephson junctions and investigate conditions needed for the formation of a rectangular fluxon lattice required for a high power flux-flow oscillator. We fabricate junctions of different sizes from Bi2Sr2CaCu2O8+x and Bi1.75Pb0.25Sr2CaCu2O8+x single crystals using the mesa technique and study the Fraunhofer-like modulation of the critical current with magnetic field. The modulation can be divided into three regions depending on the formed fluxon lattice. At low field, no periodic modulation and no ordered fluxon lattice is found. At intermediate fields, modulation with half-flux quantum periodicity due to a triangular lattice is seen. At high fields, the rectangular lattice gives integer flux quantum periodicity. We present these fields in dependence on the sample size and conclude that the transitions between the regions depend only on lambdaJ(Jc) and occur at about 0.4 and 1.3 fluxons per lambdaJ, respectively. These numbers are universal for the measured samples and are consistent with performed numerical simulations.

Dual-transducer ultrasound for elastography
Creators: name: Abeysekera, Jeffrey Michael
Publisher: name: University of British Columbia
Year: 2010

description: Medical imaging techniques provide valuable information about the internal anatomy of the body. Commonly used techniques can render many properties of the anatomy and its function, but they are limited in their ability to measure tissue mechanical properties such as elasticity. Over the past two decades there has been growing interest in developing methods of noninvasively characterizing mechanical properties of tissues; a field commonly referred to as elastography. Tissues are known to exhibit changes in mechanical properties in response to pathology. As a result, elastography has the particular potential to help physicians diagnose and locate cancerous tumors and other malignancies. The principle of operation of elastography systems is to apply an excitation to the tissue, such as a compression, and to measure the resulting tissue motion as it deforms. The tissue elasticity can then be inferred from the motion estimates by solving the inverse problem. Tissue motion is typically measured with ultrasound because it is fast, safe, and relatively inexpensive. The point spread function of an ultrasound beam is anisotropic, resulting in poorer quality motion estimates in two of the three spatial directions. This thesis investigates a new method of estimating tissue motion by employing two ultrasound transducers with different view angles. The goal of using these two transducers is to create a plane of high quality 2D motion estimates. Simulations and experimental results on tissue mimicking phantoms show that the method outperforms other commonly used 2D motion estimation methods. For example, in a tissue deformation simulation, the dual transducer method produced lower root mean square measurement error by a factor of 10 compared to a single transducer technique, and a factor of 3 compared to a single transducer with angular compounding. A simple wire-based method of aligning the transducers into a coincident scan plane is initially developed. Later, a novel wedge-based phantom is designed for aligning the two transducers. Calibration results demonstrate improved alignment with the wedge phantom. Manual alignment is found to be repeatable with mean alignment errors under 1 degree in rotation and 1 mm in translation for all degrees of freedom after six independent trials.
A Prospective Study of the Relationship between Peritraumatic Distress and Attentional Avoidance of Trauma-Relevant Threat in the Prediction of Posttraumatic Stress Disorder

description: The purpose of this prospective study was to increase what is known about the relationship between peritraumatic distress and threat-related attentional bias to non-recovery from trauma exposure, with the goal of improving post-traumatic stress disorder (PTSD) risk identification in a hospital emergency department setting. To do so, attentional bias and peritraumatic distress were assessed in physical assault and motor vehicle accident survivors within six hours of hospitalization, and PTSD symptom assessment was then conducted at 1- and 3-months post- trauma exposure. Primary analyses examined the role of attentional bias and peritraumatic distress in the development of PTSD symptoms, whereas secondary analyses explored the relationship between peritraumatic distress and threat-related attentional bias to independent symptom clusters comprising PTSD as a syndrome, as well as the moderating effect of blood alcohol presence on symptom prediction. Key results revealed that peritraumatic distress predicted 1-month symptoms in the study’s sample, and provided some degree of indication that attentional threat avoidance following acute trauma exposure may be related to greater 1-month PTSD symptoms. Although these variables emerged to be independent of one another, results point to the need for further investigation into the potential utility of combining peritraumatic distress and attentional bias as a screening protocol in an emergency room setting. Further, results revealed that baseline PTSD symptoms predicted greater peritraumatic distress severity, thereby offering novel insight with respect to pathways by which prior trauma exposure increases PTSD risk. Finally, it was found that peritraumatic distress and attentional bias have distinct relationships with the individual PTSD symptom clusters, and that each of these may hold different implications with respect to PTSD symptom heterogeneity. Considered together, the results contribute to researchers’ and clinicians’ understanding of PTSD onset and chronicity.

description: Understanding linkages between modern fluvial morphodynamic processes and their products in the rock record enables enhanced paleoenvironmental and stratigraphic interpretations. A significant challenge to interpretations is the disparity in information available from modern environments and ancient outcrop or subsurface data sets. Limited exposure in outcrop belts and widely spaced or low-resolution perspectives in the subsurface make interpretations challenging. In order to address these challenges, a comprehensive series of data sets, including a numerical model of meandering channels, the floodplain of the lower Mississippi River, outcropping deposits of the Horseshoe Canyon Formation, and the subsurface McMurray Formation, have been compiled in order to deduce evolutionary stages and characterize deposits of meander belts. A variety of methods are employed, including outcrop characterization, seismic interpretation, statistical modeling, and paleochannel reconstructions. Novel approaches to quantifying meander-bend accretion directions, and the deposition and preservation histories of meander-belt deposits, are significant contributions of this study. The study provides insight into the controlling processes of preservation, with implications for the “Sadler Effect” and the completeness of the stratigraphic record. Through the integration of a wide range of data sets, the expression of morphodynamic processes that are commonly observed in modern systems is identified in the rock record – these insights are incorporated into geocellular models, for the purpose of optimal reservoir predictions in meanderbelt reservoirs. At the meander-bend scale, stratigraphic evidence for a series of processes are featured, including: (1) intra-point-bar erosion and rotation; (2) meander-bend limb migration and the formation of side bars; (3) mid-channel bar deposition; and (4) flow separation around downstream translating bars and the formation of counter-point bars (i.e., concave bank benches). At the meander-belt scale, reconstructed paleochannel migration patterns reveal the evolutionary history of the various deposits studied. Meander-belt deposition and preservation is quantified. The “survivability”, or preservation potential of a meander-belt deposit over time, follows a natural logarithmic function of decay.

description: A virtual substrate for high quality InAs epitaxial layer has been attained via metalorganic vapor-phase epitaxy growth of Sb-assisted InxGa1-xAs metamorphic buffers, following a convex compositional continuous gradient of the In content from x = 53 % to 100 %. The use of trimethylantimony (or its decomposition products) as a surfactant has been found to crucially enable the control over the defect formation during the relaxation process. Moreover, an investigation of the wafer offcut-dependence of the defect formation and surface morphology has enabled the achievement of a reliably uniform growth on crystals with offcut towards the [111]B direction.

description: Youth with complex needs in the child welfare population are at increased risk of many negative life outcomes. A large body of research documents the factors that contribute to these difficulties. However, few studies have investigated the factors that facilitate positive outcomes for vulnerable youth. The present study provides some answers by investigating the strength of youth’s connections with caring adults as a significant mediator of the association between perceived emotional social support and personal well-being in a sample of 25 youth with complex needs in care. The results show that strong connections with caring adults mediates the association between perceived emotional social support and personal well-being. Implications for professionals, service providers, and larger systems are discussed. The findings of this study offer hope for youth in care at risk of poor outcomes, as strong relationships with caring adults can make a significant difference in their lives.

description: We study the interplay between the edge states and a single impurity in a zigzag graphene nanoribbon. We use tight-binding exact diagonalization techniques, as well as density functional theory calculations to obtain the eigenvalue spectrum, the eigenfunctions, as well the dependence of the local density of states (LDOS) on energy and position. We note that roughly half of the unperturbed eigenstates in the spectrum of the finite-size ribbon hybridize with the impurity state, and the corresponding eigenvalues are shifted with respect to their unperturbed values. The maximum shift and hybridization occur for a state whose energy is inverse proportional to the impurity potential; this energy is that of the impurity peak in the DOS spectrum. We find that the interference between the impurity and the edge gives rise to peculiar modifications of the LDOS of the nanoribbon, in particular to oscillations of the edge LDOS. These effects depend on the size of the system, and decay with the distance between the edge and the impurity.

description: We revisit the nonlinear second-order differential equations $$
 \ddot{x}(t)=a (x )\dot{x}(t)^2+b(t)\dot{x}(t)
 $$ where $a(x)$ and $b(t)$ are arbitrary functions on their argument from the perspective of Lie-Hamilton systems. For the particular choice $a(x)=3/x$ and $b(t)=1/t$, these equations reduce to the Buchdahl equation considered in the context of General Relativity. It is shown that these equations are associated to the 'book' Lie algebra $\mathfrak{b}_2$, determining a Lie-Hamilton system for which the corresponding $t$-dependent Hamiltonian and the general solution of the equations are given. The procedure is illustrated considering several particular cases. We also make use of the quantum deformation of $\mathfrak{b}_2$ with quantum deformation parameter $z$ (where $q={\rm e}^z$), leading to a deformed generalized Buchdahl equation. Applying the formalism of Poisson-Hopf deformations of Lie-Hamilton systems, we derive the corresponding deformed $t$-dependent Hamiltonian, as well as its general solution. The generalized Buchdahl equation is further extended to the oscillator Lie-Hamilton algebra $\mathfrak{h}_4\supset \mathfrak{b}_2$, together with its quantum deformation, and the corresponding (deformed) equations are also analyzed for their exact solutions. The presence of the quantum deformation parameter $z$ is interpreted as the introduction of an integrable perturbation of the (initial) generalized Buchdahl equation, which is described in detail in its linear approximation. Finally, it is also shown that, under quantum deformations, the higher-dimensional deformed generalized Buchdahl equations from either the book or the oscillator algebras do not reduce to a sum of copies of the initial system but to intrinsic coupled systems governed by $z$.

Pulse Shape Analysis with scintillating bolometers

Subjects: subject: Nuclear Experiment (nucl-ex)

description: Among the detectors used for rare event searches, such as neutrinoless Double Beta Decay (0$ν$DBD) and Dark Matter experiments, bolometers are very promising because of their favorable properties (excellent energy resolution, high detector efficiency, a wide choice of different materials used as absorber, ...). However, up to now, the actual interesting possibility to identify the interacting particle, and thus to greatly reduce the background, can be fulfilled only with a double read-out (i.e. the simultaneous and independent read out of heat and scintillation light or heat and ionization). This double read-out could greatly complicate the assembly of a huge, multi-detector array, such as CUORE and EURECA. The possibility to recognize the interacting particle through the shape of the thermal pulse is then clearly a very interesting opportunity. While detailed analyses of the signal time development in purely thermal detectors have not produced so far interesting results, similar analyses on macro-bolometers ($\sim$10-500 g) built with scintillating crystals showed that it is possible to distinguish between an electron or $γ$-ray and an $α$ particle interaction (i.e. the main source of background for 0$ν$DBD experiments based on the bolometric technique). Results on pulse shape analysis of a CaMoO$_4$ crystal operated as bolometer is reported as an example. An explanation of this behavior, based on the energy partition in the heat and scintillation channels, is also presented.

From phonology to syntax — and back again: Hierarchical structure in Irish and Blackfoot

description: The interface between phonology and syntax is a tool that can be used to provide additional evidence for study in one grammatical component or the other. Through understanding how these components interact, one can use syntactic constituent structure to control for prosodic confounds in experimentation. Conversely, one can use phonological evidence to decide between competing syntactic analyses. In ideal cases, phonological and syntactic evidence can be used in tandem, allowing converging evidence to reinforce a hypothesis. In this dissertation, I undertake three case studies to highlight: i. how a knowledge of syntactic constituent structure can increase control over prosodic variables and enable more efficient phonological research; ii. how an understanding of prosodic constituent structure can be used to motivate an underlying syntactic structure at spell-out and enable analysis of morphosyntactic features and operations before spell-out; and, iii. how the use of phonological and syntactic study in tandem can help rule out competing analyses. The first case study utilizes an analysis of syntactic constituent structure to control for different levels of prosodic prominence. The analysis of prominence made possible by syntactic assumptions allows the establishment of a hypothesis into the origins of a stress-shift phenomenon in one dialect of Irish. The second case study correlates observable sound alternations to prosodic boundaries and morpho-syntactic categories in Blackfoot. The analysis of prosodic structure facilitates the formation of a hypothesis about suffixation that is suggested to be the result of syntactic agreement, rather than head-movement operations. The third case study uses the phonological and syntactic analyses from both of the preceding studies and applies those findings to analyze the prosodic and syntactic constituency of demonstratives in both Irish and Blackfoot. A hypothesis towards a common structure for nominal expressions in the two languages is suggested, despite obvious surface differences in realization. Finally, predictions based on that hypothesis are made with questions for future cross-linguistic research. Each of the case studies examined herein contribute to the over-arching goal of the dissertation: To understand how cross-component evidence can provide additional insight and research tools towards a specific problem in one grammatical component or the other.

description: Floating Treatment Wetlands (FTWs) are a means of stabilization pond enhancement by providing a floating platform for vegetation that sits atop a water body. To determine the impacts of FTWs, a pilot-scale stabilization pond system was constructed at the Carseland Sewage Lagoons in Southern Alberta, Canada. Treatment cells with FTWs (22% surface coverage) and control cells were exposed to low and high nutrient wastewater from May to October, in 2015 and 2016. Results indicate FTW cells do not outperform control cells (with the exception of ammonium) when treating low nutrient influent. However FTW cells significantly improved the removal efficiency of several pollutants including reactive and total phosphorus, ammonia, nitrate, total nitrogen and biochemical oxygen demand when treating high nutrient influent. The FTW also significantly reduced temperature, electrical conductivity, dissolved oxygen, and pH. Therefore FTWs are an ideal, passive treatment enhancement for stabilization ponds, particularly when treating high nutrient wastewater.

description: Water is present during all stages of star formation: as ice in the cold outer parts of protostellar envelopes and dense inner regions of circumstellar disks, and as gas in the envelopes close to the protostars, in the upper layers of circumstellar disks and in regions of powerful outflows and shocks. In this paper we probe the mechanism regulating the warm gas-phase water abundance in the innermost hundred AU of deeply embedded (Class~0) low-mass protostars, and investigate its chemical relationship to other molecular species during these stages. Millimeter wavelength thermal emission from the para-H2-18O 3(1,3)-2(2,0) (Eu=203.7 K) line is imaged at high angular resolution (0.75"; 190 AU) with the IRAM Plateau de Bure Interferometer towards the deeply embedded low-mass protostars NGC 1333-IRAS2A and NGC 1333-IRAS4A. Compact H2-18O emission is detected towards IRAS2A and one of the components in the IRAS4A binary; in addition CH3OCH3, C2H5CN, and SO2 are detected. Extended water emission is seen towards IRAS2A, possibly associated with the outflow. The detections in all systems suggests that the presence of water on <100 AU scales is a common phenomenon in embedded protostars. We present a scenario in which the origin of the emission from warm water is in a flattened disk-like structure dominated by inward motions rather than rotation. The gas-phase water abundance varies between the sources, but is generally much lower than a canonical abundance of 10^-4, suggesting that most water (>96 %) is frozen out on dust grains at these scales. The derived abundances of CH3OCH3 and SO2 relative to H2-18O are comparable for all sources pointing towards similar chemical processes at work. In contrast, the C2H5CN abundance relative to H2-18O is significantly lower in IRAS2A, which could be due to different chemistry in the sources.

description: We consider a modified formulation for the recently developed new approach in the continuum solvation theory (Basilevsky, M. V., Grigoriev, F. V., Nikitina, E. A., Leszczynski, J., J. Phys. Chem. B 2010, 114, 2457), which is based on the exact solution of the electrostatic Poisson equation with the space-dependent dielectric permittivity. Its present modification ensures the property curl E = 0 for the electric strength field E inherent to this solution, which is the obligatory condition imposed by Maxwell equations. The illustrative computation is made for the model system of the point dipole immersed in a spherical cavity of excluded volume.

description: The placement process is a key step in physical design as it directly impacts circuit performance, area, power consumption, reliability, and the quality of other steps, such as routing, in the physical design flow. The placement problem has become ever more complex and challenging due to a wide variety of intricate constraints and design rules imposed by modern technology processes on the Very Large Scale Integration (VLSI) design process. Any constraint not only makes the placement problem challenging; but also can degrade the quality of the objectives optimized during the placement process or other steps in the physical design flow. In addition, with increases in complicated constraints and in the number of circuit components, the runtime and scalability of algorithms used in the placement process has become critical. In this thesis, a high-performance modern technology-driven placer called Eh?Placer is presented to address the challenges rising in modern technology processes. Eh?Placer is a comprehensive placement framework that provides solutions while observing modern technology constraints and routability, and optimizing wire length. Addressing the sheer number of circuit components using parallel computing methods makes Eh?Placer one of the fastest placement tools. In addition to Eh?Placer, a robust and fast legalization framework developed for standard-cell placement is presented. The proposed framework effectively legalizes input placements while minimizing the maximum and average cell movements using a novel global network-flow based approach. In addition, the developed legalizer is the only network flow based approach to observe modern technology constraints. In contrast to the traditional network flow based legalizers, areas with high cell utilization are legalized by finding several candidate paths where there is no need for the post-process step. The proposed legalizer is scalable and robust with respect to the floorplan complexity.

description: We develop and demonstrate a classification system constituted by several Support Vector Machines (SVM) classifiers, which can be applied to select quasar candidates from large sky survey projects, such as SDSS, UKIDSS, GALEX. How to construct this SVM classification system is presented in detail. When the SVM classification system works on the test set to predict quasar candidates, it acquires the efficiency of 93.21% and the completeness of 97.49%. In order to further prove the reliability and feasibility of this system, two chunks are randomly chosen to compare its performance with that of the XDQSO method used for SDSS-III's BOSS. The experimental results show that the high faction of overlap exists between the quasar candidates selected by this system and those extracted by the XDQSO technique in the dereddened i-band magnitude range between 17.75 and 22.45, especially in the interval of dereddened i-band magnitude < 20.0. In the two test areas, 57.38% and 87.15% of the quasar candidates predicted by the system are also targeted by the XDQSO method. Similarly, the prediction of subcategories of quasars according to redshift achieves a high level of overlap with these two approaches. Depending on the effectiveness of this system, the SVM classification system can be used to create the input catalog of quasars for the GuoShouJing Telescope (LAMOST) or other spectroscopic sky survey projects. In order to get higher confidence of quasar candidates, cross-result from the candidates selected by this SVM system with that by XDQSO method is applicable.

description: We present a detailed analysis on the effect of using different algorithms to model the reconnection of vortices in quantum turbulence, using the thin-filament approach. We examine differences between four main algorithms for the case of turbulence driven by a counterflow. In calculating the velocity field we use both the local induction approximation (LIA) and the full Biot-Savart integral. We show that results of Biot-Savart simulations are not sensitive to the particular reconnection method used, but LIA results are.
