description: The objective of this publication is to reduce the sensitivity of iterative equation solvers on the initial value. To this end, at the hand of Newton's method, we exemplify how to reformulate the initial problem by means of a set of generalized moment generating functions. The approach allows to choose that very function, which is best approximated by a linear function and thus allows to set up an efficient iteration procedure. As a result of this, the number of iterations required to meet a given precision goal is significantly reduced in comparison to Newton's method especially for large deviations between the initial value and the actual root. At the hand of seven academic examples and three applications we demonstrate that the computing time of the discussed approach reveals a far lower susceptibility on the initial value when compared to results from Newton's method. This insensitivity offers the prospect to implement iterative equation solvers for applications with strict real-time requirements such as power system simulation or on-demand control algorithms on embedded systems with low computing power. We are confident that the devised methodology may be generalized to other well-established iteration algorithms.

description: With characteristics of river continuum, stream ecosystems have diverse components and environments from upstream channel to estuarine area. Therefore, the habitat requirements and composition of conservative object should be well understood before applying any improvement measure. In this paper, the causes of stream habitat changes were first illustrated with the categories and principles of habitat restoration methods. The structural restoration techniques of fish habitat improvement, including dam partial-removal, utilized by the authors for two research projects during last dozen years were then presented. Through the introductions on the project background, planning guidelines, structure design, and ecological evaluation, this paper tried to provide some effective examples of ecological engineering that ecological experts were invited for cooperation and advising.

A Continuation Method for Nash Equilibria in Structured Games

Year: 2011
Subjects: subject: Computer Science and Game Theory (cs.GT)

description: Structured game representations have recently attracted interest as models for multi-agent artificial intelligence scenarios, with rational behavior most commonly characterized by Nash equilibria. This paper presents efficient, exact algorithms for computing Nash equilibria in structured game representations, including both graphical games and multi-agent influence diagrams (MAIDs). The algorithms are derived from a continuation method for normal-form and extensive-form games due to Govindan and Wilson; they follow a trajectory through a space of perturbed games and their equilibria, exploiting game structure through fast computation of the Jacobian of the payoff function. They are theoretically guaranteed to find at least one equilibrium of the game, and may find more. Our approach provides the first efficient algorithm for computing exact equilibria in graphical games with arbitrary topology, and the first algorithm to exploit fine-grained structural properties of MAIDs. Experimental results are presented demonstrating the effectiveness of the algorithms and comparing them to predecessors. The running time of the graphical game algorithm is similar to, and often better than, the running time of previous approximate algorithms. The algorithm for MAIDs can effectively solve games that are much larger than those solvable by previous methods.

description: The imaging performance of a high-resolution preclinical microPET system employing liquid xenon as the gamma ray detection medium was simulated. The arrangement comprises a ring of detectors consisting of trapezoidal LXe time projection ionization chambers and two arrays of large area avalanche photodiodes for the measurement of ionization charge and scintillation light. A key feature of the LXePET system is the ability to identify individual photon interactions with high energy resolution and high spatial resolution in 3 dimensions and determine the correct interaction sequence using Compton reconstruction algorithms. The simulated LXePET imaging performance was evaluated by computing the noise equivalent count rate, the sensitivity and point spread function for a point source, and by examining the image quality using a micro-Derenzo phantom according to the NEMA-NU4 standard. Results of these simulation studies included NECR peaking at 1326 kcps at 188 MBq (705 kcps at 184 MBq) for an energy window of 450 - 600 keV and a coincidence window of 1 ns for mouse (rat) phantoms. The absolute sensitivity at the center of the field of view was 12.6%. Radial, tangential, and axial resolutions of 22Na point sources reconstructed with a list-mode maximum likelihood expectation maximization algorithm were <= 0.8 mm (FWHM) throughout the field of view. Hot-rod inserts of < 0.8 mm diameter were resolvable in the transaxial image of a micro-Derenzo phantom. The simulations show that a liquid xenon system would provide new capabilities for significantly enhancing PET images.

description: A revival over the past two decades in planetary nebula (PN) morphological studies springs from a combination of factors, including the advent of wide-area, high dynamic range detectors; the growing archives of high resolution images from the X-ray to the sub-mm; and the advent of sophisticated models of the co-evolution of PNe and their central stars. Yet the story of PN formation from their immediate precursors, the AGB stars, is not yet fully written. PN morphology continues to inspire, provide context for physical interpretation, and serve as an ultimate standard of comparison for many investigations in this area of astrophysics. After a brief review of the remarkable successes of PN morphology, I summarize how this tool has been employed over the last half-decade to advance our understanding of PNe.

description: Using the grid diagram formulation of knot Floer homology, Ozsvath, Szabo and Thurston defined an invariant of transverse knots in the tight contact 3-sphere. Shortly afterwards, Lisca, Ozsvath, Stipsicz and Szabo defined an invariant of transverse knots in arbitrary contact 3-manifolds using open book decompositions. It has been conjectured that these invariants agree where they are both defined. We prove this fact by defining yet another invariant of transverse knots, showing that this third invariant agrees with the two mentioned above.

description: We construct solutions of the paraxial and Helmholtz equations which are polynomials in their spatial variables. These are derived explicitly using the angular spectrum method and generating functions. Paraxial polynomials have the form of homogeneous Hermite and Laguerre polynomials in Cartesian and cylindrical coordinates respectively, analogous to heat polynomials for the diffusion equation. Nonparaxial polynomials are found by substituting monomials in the propagation variable $z$ with reverse Bessel polynomials. These explicit analytic forms give insight into the mathematical structure of paraxially and nonparaxially propagating beams, especially in regards to the divergence of nonparaxial analogs to familiar paraxial beams.

Effects of acute salinity and temperature change on Pacific hagfish, Eptatretus stoutii; implications for bycatch post release survival
Creators: name: Hastey, John Pinkerton
Publisher: name: University of British Columbia
Year: 2011

description: Hagfish captured as bycatch in a commercial fishery may be exposed to a range of elevated temperatures and reduced salinities when brought to the surface but it is not known how this will affect post-release survival. In this study, hagfish were exposed to all combinations of four salinities (33, 28, 23, and 18 g/l) and three temperatures (7, 16 and 25˚C) and sampled following 1, 3 or 6 h exposure to investigate sub-lethal affects on plasma osmolality, [Na⁺], [Cl⁻], [Mg²⁺], and glucose, hematocrit, mean cell haemoglobin concentration , muscle water content, as well as behavioural responses and survival. An additional group of hagfish were sampled after 48 h of recovery (33 g/l at 7˚C) following 3 h exposure to all salinity/temperature combinations to investigate latent effects of exposures. In general, during exposure to salinity and temperature combinations, plasma osmolality, [Na⁺] and [Cl⁻] decreased as: i) the salinity of exposure was reduced, ii) the duration of exposure was increased or iii) the temperature to which hagfish were exposed was increased. Plasma osmolality did not equilibrate with environmental osmolality within 6 h and appeared to approach an asymptote at 60% equilibration. Behavioural effects were observed during exposure to reduced salinity conditions at all temperatures and included full body contractions, reduced slime production, reduced swimming ability, extended body posture. During exposure to 25˚C, hagfish were often unresponsive to touch. Following 48 h of recovery from 3 h exposure to all salinity/temperature combinations most of the parameters measured were restored, with the exception of plasma glucose levels which remained elevated indicating latent stress. Following recovery from exposure to 23 and 18 g/l at 25˚C, morbidity levels of 14 and 100% were observed. Thus, hagfish captured and immediately brought to the surface and released, without exposure to extreme salinity or temperatures, may not physiologically be negatively affected by a catch and release fishery however, diminished survival should be expected if exposure salinity approaches 18 g/l or water temperature approaches 25˚C. Future research should address the implications of observed behaviours on release survival of hagfish in a natural setting.

description: Thermoelectric coefficients of a two dimensional electron gas with the Rashba spin-orbit interaction are presented here. In absence of magnetic field, thermoelectric coefficients are enhanced due to the Rashba spin-orbit interaction. In presence of magnetic field, the thermoelectric coefficients of spin-up and spin-down electrons oscillate with different frequency and produces beating patterns in the components of the total thermoelectric power and the total thermal conductivity. We also provide analytical expressions of the thermoelectric coefficients to explain the beating pattern formation. We obtain a simple relation which determines the Rashba SOI strength if the magnetic fields corresponding to any two successive beat nodes are known from the experiment.

description: An intermediate-scale experiment was conducted to investigate the behavior of a viscous LNAPL under variable water table conditions. Two LNAPL volumes were released from a small source zone on top of the flow cell into a partly saturated, homogenously packed porous medium. Following a 30-day redistribution period, the water table was increased 0.5 m in 50 minutes. After the water table rise, LNAPL behavior was monitored for an additional 45 days. Fluid saturation scans were obtained periodically with a fully automated dual-energy gamma radiation system. Results show that both spills follow similar paths downwards. LNAPL drainage from the unsaturated zone was relatively slow and a considerable residual LNAPL saturation was observed after 30 days of drainage. Most of the mobile LNAPL moved into the capillary fringe during this period. After the water table rise, LNAPL moved up in a delayed fashion. After 45 days, the LNAPL has moved up only ap-proximately 0.2 m. Since the LNAPL has only moved up a limited amount, nonwetting fluid entrapment was also limited. The experiment was simulated using the STOMP multifluid flow simulator. A comparison indicates that the simulator is able to predict the observed phenomena well, including residual saturation formation in the vadose zone, and limited upward LNAPL movement after the water table rise. The results of this experiment show that viscous mobile LNAPL, subject to variable water table conditions, does not necessarily float on the water table and may not appear in an observation well.

description: Collaborative learning with peers can lead to students learning from each other and solving physics problems correctly not only in situations in which one student knows how to solve the problems but also when none of the students can solve the problems alone. We define the rate of construction as the percentage of groups collaborating on problem-solving that solve the problem correctly out of all groups having at least one member who answered correctly and one incorrectly while solving the same problem individually first. We define the rate of co-construction on each problem as the percentage of collaborating groups that answered it correctly if no student in the group individually answered it correctly before the collaborative work. In this study, we investigated student learning measured by student performance on a validated quantum mechanics survey and rates of construction and co-construction of knowledge when students first worked individually after lecture-based instruction in relevant concepts and then worked with peers during class without receiving any feedback from the course instructor. We find that construction of knowledge consistently occurred at a high rate during peer collaboration. However, rates of co-construction were more varied. High rates of co-construction were generally achieved when approximately half of the students knew the correct answers initially. We also conducted an analysis of some of the survey questions that correlate with high rates of co-construction to gain some insight into what students converged on after peer interaction and what types of difficulties were reduced. Our findings can be valuable for instructors who want to provide in-class and out-of-class opportunities for peer collaboration in their physics courses.

description: An open quantum system with multiple levels coupled to a bosonic environment at zero temperature is investigated systematically using the non-Markovian quantum-state-diffusion (QSD) method [W. T. Strunz, L. Diósi, and N. Gisin, Phys. Rev. Lett. 82, 1801 (1999)]. We have established exact time-local QSD equations for a set of interesting multilevel open systems, including high-spin systems, multiple-transition atomic models, and multilevel atomic models driven by time-dependent external fields. These exact QSD equations have paved the way to evaluate the dynamics of open multilevel atomic systems in the general non-Markovian regimes without any approximation.

description: Das Forschungsdatenmanagement steht am Beginn eines jeden Forschungsvorhabens und sollte bis zum Ende mitgedacht werden. Eine Forschungsdatenumgebung unterstützt die Forschenden bei der Strukturierung und Analyse ihrer Daten. Diese Systeme werden meist erst während des Projektzeitraums entwickelt. Das „Wie“ und „Was“ muss also bei jedem einzelnen Projektbeginn entweder neu entworfen oder in ähnliche vergangene Formen eingefügt werden. Das am eScience-Center der Universität Tübingen entwickelte System Spacialist, verlagert die Forschungsumgebung in den virtuellen Raum. Dadurch ermöglicht es ein ortsungebundenes und kollaboratives Arbeiten. Die Datenaufnahme in das generisch definierte Datenmodell standardisiert die Datenstruktur und garantiert dadurch eine qualitative Analyse der Daten. Die Forschungsdaten können im System kommentiert, validiert und gegebenenfalls korrigiert werden. Dabei unterstützen ein integriertes Moderationssystem mit Rollenvergabe, eine Kommentarspalte sowie Möglichkeiten zur Referenzierung von Literatur oder auf in der integrierten Dateiverwaltung hinterlegten Dateien. Ebenfalls können Geodaten und benutzerdefinierte Kartenlayer verwendet werden, um raumbezogene Daten zu erfassen und einzubeziehen. Die Entwicklung von Spacialist ist von Anfang an transparent gestaltet, um das System auf die Workflows der Fachbereiche auszurichten. Die dabei einbezogenen Fachcommunities der Digital Humanities haben darüber hinaus die Möglichkeit Spacialist durch Plugins zu erweitern und an spezifische Anforderungen anzupassen. Zudem können die Forschungsergebnisse unkompliziert in bestehende (universitäre) Archivsysteme integriert werden.

description: Spontaneous jet ignition, consisting of ignition during early, transient stages of gaseous fuel outflow, like hydrogen, due to a sudden rupture of a high pressure reservoir into atmosphere, was first observed by Wolanski and Wojcicki in 1973. The phenomenon clearly has an important role in hydrogen safety, increasing the risk of explosions. One potential explanation is that the combined effect of heat and mass diffusion at the contact surface, separating the expanded and cooled hydrogen from shocked hence compressed and heated air, leads to ignition. Experimental and numerical evidence shows that the size of the release opening is a crucial parameter with ignition being more likely for larger openings. The structures of the shock and contact surface are multi-dimensional which makes the numerical attempts limited to computational capabilities. However, for constant pressure and planar geometry this process was analyzed by Linan and Crespo in the limit of high activation energy for single step Arrhenius kinetics and unity Lewis number. In the current study, the analysis is extended to account for different fuel mass diffusivities and expansion due to evolution of the shock. The analysis shows that ignition can occur for fuels with higher mass diffusivity like hydrogen, with Lewis number less than unity, but that it does not occur for fuels such as hydrocarbons, with Lewis number greater than unity. In the former case, it also identifies a critical value for expansion, separating situations whereby ignition is inhibited from cases in which ignition will occur.

description: A class of problems in hydrology and remote sensing requires improved understanding of how water and heat flux boundary conditions affect the soil moisture processes in the shallow subsurface near the land/atmospheric interface. In these systems, a clear understanding of how variations in water content, soil drainage/wetting and porosity conditions affect the soil's thermal behavior is needed for the accurate detection of buried objects such as landmines, however, very few experimental data showing the effects of these variations are available. In this study, the effect of soil moisture, soil hysteretic behavior and porosity on the thermal conductivity of some sandy soils was investigated. For this experimental investigation, a Tempe cell was modified to have a network of sampling ports, continuously monitoring water saturation, capillary pressure, temperature, and soil thermal properties. The water table was established at mid elevation of the cell and then lowered slowly. The initially saturated soil sample was subjected to slow drainage, wetting, and secondary drainage cycles. After liquid water drainage ceased, evaporation was induced at the surface to remove soil moisture from the sample to obtain thermal conductivity data below the residual saturation. For the test soils studied, thermal conductivity increased with increasing soil density and moisture content while thermal conductivity values were similar for soil drying/wetting behavior. Thermal properties measured in this study were then compared with independent estimates made using empirical models from literature. These soils will be used in a proposed set of experiments in intermediate scale test tanks to obtain data to validate methods and modeling tools used for landmine detection.
Looking beyond the whiteboard : investigating first year teaching and the beginning teacher through transdisciplinary inquiry
Creators: name: Mei, Linda Yu Hui
Publisher: name: University of British Columbia
Year: 2011

description: The beginning teacher’s story is one that is rarely told. Amidst the theory-versus-practice dilemmas and judgement by self and others, a beginning teacher can easily lose his or her sense of self. The beginning teacher often naïvely believes that expert colleagues’ teaching styles and techniques can and should be imitated. However, employing others’ techniques and teaching as someone else does not always produce satisfactory results, and often, these sometimes desperate measures can also make the novice practitioner disillusioned about his or her identity, as well as the reasons for choosing this profession. This thesis explores the possibilities of how a reflection guided by the principles of transdisciplinary inquiry can help the beginning teacher understand the complexities of teaching and the teacher identity. Transdisciplinary inquiry acts as a set of lenses that transcend existing ways of investigation. In essence, transdisciplinary inquiry encompasses elements of self-reflexivity, plurality, and complexity, which enable a more insightful approach to reflection in real life settings. In this thesis, I reflected on my first year of teaching by analyzing and examining six anecdotes written in the form of narratives. Borrowing from Schön’s (1983, 1987) model of reflective practice, I approached the narratives by first identifying a trigger, followed by framing, then reframing the questions or key ideas, before eventually determining the most suitable future action. Knowledge of one’s identity through reflection is essential in this profession, for it is not merely teaching techniques that create a good teacher, but an awareness of oneself. I argue that good teaching emerges from one’s identity because our personalities, values, and experiences influence how we teach and why we teach. This thesis is an attempt to trace and document that process for my own practice as a beginning teacher.
Proving existence results in martingale theory using a subsequence principle

description: New proofs are given of the existence of the compensator (or dual predictable projection) of a locally integrable cádlág adapted process of finite variation and of the existence of the quadratic variation process for a cádlág local martingale. Both proofs apply a functional analytic subsequence principle. After presenting the proofs, we discuss their application in giving a simplified account of the construction of the stochastic integral of a locally bounded predictable process with respect to a semimartingale.

description: W 3. CORDULIA  ALPESTRIS.  (Nobis.)    GORDULIE .
 Diagnose. — Vert-bronzé. Une tache devant chaque oeil et la base de la lèvre supérieure jaunes.
 Dimensions. — (Voyez le tableau.)   Synonymie.
 ♂. Diffère de celui de la Metallica:
 1 ° En ce qu’il est plus petit;
  2° Le  front n’a pas de bande transverse jaune, mais simplement deux taches devant les yeux comme la Flavomaculala;
  3° Les  pieds sont tout noirs;
 4° L’abdomen, qui est d’un vert bronzé plus foncé et moins cuivré, n’a que le bord postérieur du deuxième segment jaune, et le prolongement de ce bord, qui renferme les organes génitaux accessoires, est beaucoup moins proéminent et se trouve séparé en deux tubercules latéraux au lieu d’être réuni en arrière;
 5° Les appendices anals supérieurs sont plus distinctement brisés en trois parties; la dernière étant munie en dehors d’une dent pointue comme celle de la base, et fléchie davantage en dedans; l’inférieur est proportionnellement plus large et plus court que chez la Metallica;
 6° Le parastigma est brun-noirâtre; il n’y a que peu de jaunâtre près de la membranule accessoire.
 ♀. Elle a la tête, les pieds et l’abdomen comme le mâle, sauf une tache jaune aux côtés du deuxième segment. Les bords postérieurs du huitième semblent prolongés en dessous en une simple écaille concave, en gouttière et courte (et non en appendice long comme la Metallica). Ailes lavées uniformément de jaunâtre sale. Parastigma brun. Membranule accessoire cendrée.
 J’ai pris trois individus de cette nouvelle espèce le 15 juillet, dans I’Oberland bernois, à la même localité que j ’ ai indiquée à l’article de la Libellula rubicunda . Elle y semblait assez commune et volait accouplée.
 Par le facieset la couleur du front, elle est absolument intermédiaire entre la Metallica et l' AEnea. Quand même on supposerait que les petites différences qui existent entre les appendices anals de la Metallica et de YAlpestris ne sont dues qu’à des variétés locales ou individuelles, l'organisation différente des organes génitaux dans les deux sexes et la coloration du front, qui n’est nullement variable dans ce genre, prouveront suffisamment, je pense, que c’est à bon droit que j’ai établi cette espèce.

description: A three-phase contact line in a three-phase fluid system is modeled by a mean-field density functional theory. We use a variational approach to find the Euler-Lagrange equations. Analytic solutions are obtained in the two-phase regions at large distances from the contact line. We employ a triangular grid and use a successive over-relaxation method to find numerical solutions in the entire domain for the special case of equal interfacial tensions for the two-phase interfaces. We use the Kerins-Boiteux formula to obtain a line tension associated with the contact line. This line tension turns out to be negative. We associate line adsorption with the change of line tension as the governing potentials change.
