description: An experimental demonstration of a parametric oscillation of a magnetization in a ferromagnet was performed recently by applying a microwave voltage, indicating the potential to be applied in a switching method in non-volatile memories. In the previous works, the modulation of a perpendicular magnetic anisotropy field produced by the microwave voltage was small compared with an external magnetic field pointing in an in-plane direction. A recent trend is, however, opposite, where an efficiency of the voltage controlled magnetic anisotropy (VCMA) effect is increased significantly by material research and thus, the modulated magnetic anisotropy field can be larger than the external magnetic field. Here, we solved the Landau-Lifshitz-Gilbert equation numerically and investigated the magnetization dynamics driven under a wide range of the microwave VCMA effect. We evaluated bifurcation diagrams, which summarize local maxima of the magnetization dynamics. For low modulation amplitudes, the local maximum is a single point because the dynamics is the periodic parametric oscillation. The bifurcation diagrams show distributions of the local maxima when the microwave magnetic anisotropy field becomes larger than the external magnetic field. The appearance of this broadened distribution indicates complex dynamics such as chaotic and transient-chaotic behaviors, which were confirmed from an analysis of temporal dynamics.

description: The Asakura-Oosawa model for colloid-polymer mixtures is studied by Monte Carlo simulations at densities inside the two-phase coexistence region of fluid and solid. Choosing a geometry where the system is confined between two flat walls, and a wall-colloid potential that leads to incomplete wetting of the crystal at the wall, conditions can be created where a single nanoscopic wall-attached crystalline cluster coexists with fluid in the remainder of the simulation box. Following related ideas that have been useful to study heterogeneous nucleation of liquid droplets at the vapor-liquid coexistence, we estimate the contact angles from observations of the crystalline clusters in thermal equilibrium. We find fair agreement with a prediction based on Young's equation, using estimates of interface and wall tension from the study of flat surfaces. It is shown that the pressure versus density curve of the finite system exhibits a loop, but the pressure maximum signifies the "droplet evaporation-condensation" transition and thus has nothing in common with a van der Waals-like loop. Preparing systems where the packing fraction is deep inside the two-phase coexistence region, the system spontaneously forms a "slab state", with two wall-attached crystalline domains separated by (flat) interfaces from liquid in full equilibrium with the crystal in between; analysis of such states allows a precise estimation of the bulk equilibrium properties at phase coexistence.

Hand-rearing harbour seal pups (Phoca vitulina) : the effect of diet and supplementary heat on growth and survival
Creators: name: MacRae, Amelia
Publisher: name: University of British Columbia
Year: 2010

description: Hundreds of stranded harbour seals pups (Phoca vitulina) are brought to wildlife rescue centres every year, often unweaned and in poor body condition. Typical hand-rearing diets include artificial milk-replacers and diets based on macerated fish, both normally fed via gavage. Mortality rates for these animals can be high and weight gains on artificial formulas are low. This study was designed to determine the effect of the following treatments on the growth and survival of captive orphaned seals: (1) feeding pups an artificial milk-replacer versus a fish-based formula; and (2) the provision of supplementary heat. Pups admitted to the facility in summer 2007 (n=145) and 2008 (n=98) were randomly assigned to one of two diets and fed until weaning at roughly 20 days of age. In 2008, 25 pups were also provided with a supplementary heat source. Diet and heat treatments were compared using average daily gain (ADG) and mortality rates. In 2007, with pups fed formulas at 8% of body weight per day, pups fed milk-replacer gained more (43 g/d ± 12, mean ± SEM) than those fed fish-formula (loss of 13 g/d ± 6; p<0.01) and their survival to weaning was twice as high (p<0.05, chi-squared analysis). In 2008, with daily intake increased to 11% of body weight per day, weight gain was improved for both diets but remained higher on milk-replacer (123 g/d ± 12, loss of 6 g/day ± 8; p<0.01) and fewer seals died on either treatment (6/35 on milk replacer, 8/34 on fish formula.) Pups provided with heat did not show any differences in ADG (p>0.05) or survival rate (p>0.05) but did show increased heat-seeking behaviour at ambient temperatures below 16°C (p<0.001). I conclude: (1) although neither diet achieved the weight gains recorded in mother-raised pups (400 – 800 g/d), the artificial milk formula was clearly more successful; (2) supplementary heat can be safely used for unweaned pups in poor body condition at ambient temperatures <16°C; and (3) more work is needed on both diet composition and feeding method to achieve higher survival and more natural weight gains.
Bit-Serial Reed Solomon Decoders in VLSI

Publisher: name: California Institute of Technology
Year: 1984

description: Reed-Solomon codes are known to provide excellent error-correcting capabilities on many types of communication channels. Although efficient decoding algorithms have been known for over fifteen years, currently available decoder systems are large both in size and in power consumption. Such systems typically use a single, very fast, fully parallel finite-field multiplier in a sequential architecture. Thus, more processing time is required as the code redundancy increases. By using many arithmetic units on a single chip, it is possible to exploit the concurrency inherent in the decoding algorithms to attain performance levels previously possible only with large ECL systems.

An investigation into the structure of binary extension fields reveals that the common arithmetic operations used in decoding can be implemented quite efficiently in a bit-serial fashion, using any of several bases over GF(2). Berlekamp's dual-basis multiplier is generalized to the product of two arbitrary field elements, and a necessary and sufficient condition is then derived for the existence of a self-dual basis. The efficient methods presented for bit-serial multiplicative inversion greatly reduce the complexity traditionally associated with this operation.

Using these bit-serial techniques, several architectures for implementing each phase of the known Reed-Solomon decoding algorithms are presented and compared. Simple methods are presented to allow power-sum syndrome decoders to handle codes with a variety of block lengths and redundancies. Each approach comes within a factor of log n (where n is the block length of the code) of the recently derived asymptotic lower bounds for both time and area. Results from a student project to lay out a prototype decoder chip using the Berlekamp-Massey algorithm are also discussed. By utilizing the parallelism inherent in the key equation solution, these architectures can decode received words a t a speed independent of the redundancy of the code.

description: A wavelet is a localized function having a prescribed number of vanishing moments. In this correspondence, we provide precise arguments as to why the Hilbert transform of a wavelet is again a wavelet. In particular, we provide sharp estimates of the localization, vanishing moments, and smoothness of the transformed wavelet. We work in the general setting of non-compactly supported wavelets. Our main result is that, in the presence of some minimal smoothness and decay, the Hilbert transform of a wavelet is again as smooth and oscillating as the original wavelet, whereas its localization is controlled by the number of vanishing moments of the original wavelet. We motivate our results using concrete examples.

description: We have developed a compact cryogenic system with a pulse tube refrigerator and a coaxial heat exchanger. This liquefaction-purification system not only saves the cooling power used to reach high gaseous recirculation rate, but also reduces the impurity level with high speed. The heat exchanger operates with an efficiency of 99%, which indicates the possibility for fast xenon gas recirculation in a highpressurized large-scale xenon storage with much less thermal losses.

description: This dissertation focuses on the removal of cardiac CT imaging artifacts caused by motion and metal implants. A combination of model-based data synthesis and subsequent data-driven learning of image enhancement methods is proposed. Forward models for virtual artifact generation are developed by incorporating prior knowledge about the cardiac anatomy and CT imaging physics. They form the counterpart of resulting learning-based backward models, which achieve significant reduction of artifacts during testing on real data.

description: Untersuchung nichtlinearer Schiffsdynamik mit Auftreten von Instabilität und Chaos an Beispielen aus der Offshoretechnik Das dynamische Verhalten eines einpunktverankerten Tankers, eines verankerten A-Bock-Kranschiffes und eines mehrpunktverankerten Pontons wurde mittels der aufgestellten mathematischen Modelle unter Berücksichtigung signifikanter Nichtlinearitäten numerisch untersucht. Statische und dynamische Verzweigungen der Gleichgewichtslage des in konstanter Strömung verankerten Tankers wurden durch lokale lineare Stabilitätsanalysen im Parameterraum identifiziert. Global nichtlineare Simulationen zeigten, dass die Tankerbewegung im autonomen Zustand für die instabilen Fälle durch extrem langsame, selbstinduzierte Schwingungen mit großen Amplituden gekennzeichnet war. Das bei zusätzlicher Erregung durch stationären Wind oder periodische Wellen entstandene chaotische Verhalten zeigte eine außerordentliche Empfindlichkeit gegen Anfangsbedingungen. Es wurden geeignete Maßnahmen zur Stabilisierung des Gleichgewichts bzw. der Bewegung des Tankers gefunden. Für das Kranschiff in regelmäßigen Wellen wurden mittels der Fourier-Analyse Periodenvervielfachung und chaotisches Verhalten festgestellt. Für den verankerten Ponton in regelmäßigen Wellen wurde die Koexistenz zweier verschiedener Attraktoren mit Hilfe der Poincare-Abbildung veranschaulicht. Chaotisches Verhalten des verankerten Pontons in periodischen Wellengruppen wurde durch einen positiven Ljapunov-Exponenten und die fraktale Ljapunov-Dimension bestätigt.
description: Dynamic behavior of an SPM-tanker, a moored shear-leg crane ship, and a moored barge was numerically investigated using mathematical models that include significant nonlinearities. Static and dynamic bifurcations of the equilibrium of the tanker moored in a constant current were identified by locallinear stability analysis in parameter space. Global nonlinear simulations showed that tanker motions in the autonomous mode were characterized by large-amplitude, long-period self-sustained oscillations for the unstable cases. When additionally subjected to a steady wind or periodic waves, tanker motion response became chaotic. In these cases, extreme sensitivity to initial conditions was verified. Suitable measures were found to stabilize the tanker equilibrium and its motion. For the crane ship in regular waves period multiplication and chaotic behavior were determined using Fourier analysis. For the moored barge in regular waves coexistence of two different attractors was demonstrated with Poincare maps. Chaotic behavior of the moored barge in periodic wave groups was verified by a positive Lyapunov exponent and a fractal Lyapunov dimension.

description: Toral (2002) considered an ensemble of N\geq2 players. In game B a player is randomly selected to play Parrondo's original capital-dependent game. In game A' two players are randomly selected without replacement, and the first transfers one unit of capital to the second. Game A' is fair (with respect to total capital), game B is losing (or fair), and the random mixture γA'+(1-γ)B is winning, as was demonstrated by Toral for γ=1/2 using computer simulation. We prove this, establishing a strong law of large numbers and a central limit theorem for the sequence of profits of the ensemble of players for each γ\in(0,1). We do the same for the nonrandom pattern of games (A')^r B^s for all integers r,s\geq1. An unexpected relationship between the random-mixture case and the nonrandom-pattern case occurs in the limit as N\rightarrow\infty.

Integrated optical devices for free-space optical communications
Creators: name: Jin, Xian
Publisher: name: University of British Columbia
Year: 2010

description: Optical wireless communication technologies for free-space optical (FSO) transmission, distribution, and reception have numerous potential benefits. Such systems offer incredibly high data communication rates (in the same way that fibre optic technologies have revolutionized long-haul Terabit/second data transmission) together with the distributive benefits of multi-user wireless networking. Communication devices for these FSO technologies are presented in this thesis. A macroscopic passive retroreflective structure is introduced first for signal retroreflection over the full 4π steradians solid angle. Modulation is demonstrated with this structure through the use of liquid crystal switching elements. The FSO device work is then extended with an active retroreflective structure incorporating corner-cube-based retro-detection with integrated and orthogonal photodiodes. An actively-controlled differential triangulation process is demonstrated with this novel device to optimize the optical channel alignment in the FSO communication system. The proposed integrated retroreflective structures are ideally-suited to bi-directional (uplink and downlink) multi-nodal systems and have potential to be extended to ultrafast (picosecond) optical modulation in future work.
Generation West : Hungarian modernism and the writers of the Nyugat review
Creators: name: MacDonald, Agnes
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation examines how the Nyugat review played an essential role in the development of literary and cultural modernism in early twentieth century Hungary. My chief argument is that modern Hungarian literature and culture, under the auspices of Nyugat, are part of that Central European canon which had shaped some of the most influential literary and critical theories. The review nurtured over one-hundred and twenty writers, artists and intellectuals who left a lasting impact on Hungarian literature and culture. These authors are known as the Nyugat-generation, a term which I adopt as Generation West. They contributed to the journal in Budapest between 1908 and 1941. My dissertation focuses on three of the most important contributors to Nyugat: Margit Kaffka, Dezső Kosztolányi and Antal Szerb and their respective works, Colours and Years, Esti Kornél, and Journey by Moonlight. They exemplify their generations’ perspectives and illuminate the course of Nyugat over three distinct periods. Inspired by the modernist currents of Western Europe which they espoused, these writers along with other members of the Generation West experienced “in-betweenness,” a condition characterized by the values of the traditional and the modern, East and West, nation and the individual, and feudal and bourgeois, which marked and also fuelled their output. Nyugat has come to epitomize the experience of Hungarian identity expressed through the themes of nationhood, nostalgia and commemoration. To demonstrate the journal’s legacy in Hungary today, I conclude by analyzing the events of the Nyugat 100-year anniversary that took place in 2008. My dissertation tells the story of how a community of writers and artists from a small nation in East-Central Europe instituted a profound literary and cultural movement under the aegis of a journal. I consider my study a call for reworking models of literary and cultural history and for expanding existing epistemologies of modernism.

description: A novel class of graphs, here named quasiperiodic, are constructed via application of the Horizontal Visibility algorithm to the time series generated along the quasiperiodic route to chaos. We show how the hierarchy of mode-locked regions represented by the Farey tree is inherited by their associated graphs. We are able to establish, via Renormalization Group (RG) theory, the architecture of the quasiperiodic graphs produced by irrational winding numbers with pure periodic continued fraction. And finally, we demonstrate that the RG fixed-point degree distributions are recovered via optimization of a suitably defined graph entropy.

description: We provide a complete classification up to isomorphism of all smooth convex lattice 3-polytopes with at most 16 lattice points. There exist in total 103 different polytopes meeting these criteria. Of these, 99 are strict Cayley polytopes and the remaining 4 are obtained as inverse stellar subdivisions of such polytopes. We derive a classification, up to isomorphism, of all smooth embeddings of toric threefolds in $\mathbb{P}^N$ where $N\le 15$. Again we have in total 103 such embeddings. Of these, 99 are projective bundles embedded in $\mathbb{P}^N$ and the remaining 4 are blow-ups of such toric threefolds.

description: Dieser Report ist eine Erweiterung unseres Papiers "Performance of Lookup Operations in a Hypercube-based P2P Data Store: Theoretical Model and Performance Evaluation". Wir untersuchen in diesem zwei weitere Fragen: Erstens, was ist die Wahrscheinlichkeit, dass ein Lookup verloren geht und zweitens was ist die Wahrscheinlichkeit, dass ein solcher mindestens einmal dupliziert wird. Zu diesem Zweck haben wir ein Modell auf wahrscheinlichkeitstheoretischer Basis entworfen und leiten Gleichungen für obige Wahrscheinlichkeiten, ihre Erwartungswerte und Varianzen her. Weiterhin erläutern Diagramme das Verhalten des Modells.
description: This is an addendum to our report "Performance of Lookup Operations in a Hypercube-based P2P Data Store: Theoretical Model and Performance Evaluation". Here we explore two questions: First, what is the probability of a lookup to get lost and, second, what is the probability that it will be duplicated at least once. To this end, we approach the questions on a probability theoretical basis and derive equations for both probabilities, means and variances. Graphs elucidate the behavior of the model.

description: In this paper are discussed the nulling and imaging properties of monolithic pupil telescopes equipped with a focal plane waveguide array, which could be envisaged as precursor space missions for future nulling interferometers or coronagraphs searching for habitable planets outside of our solar system. Three different concepts of nulling telescopes are reviewed, namely the Super-Resolving Telescope (SRT) having multiple, non-overlapping exit sub-apertures and the Sheared-Pupil Telescope (SPT), either unmasked or masked with a Lyot stop placed at its exit pupil plane. For each case simple theoretical relationships allowing to estimate the nulling rate, Signal-to-Noise Ratio (SNR) and Inner Working Angle (IWA) of the telescope are established or recalled, and numerical simulations are conducted. The preliminary results of this study show that the most promising designs should either be a SRT of high radiometric efficiency associated with an adequate leakage calibration procedure, or a masked SPT with potentially deeper nulling rates but lower SNR, depending on what kind of performance is to be preferred.

description: The QCD gluon equation of motion is solved approximately by means of the Green function. This solution is used to reformulate the Lagrangian of QCD such that the gluon propagator appears directly in the interaction terms of the Lagrangian. The nature of the interactions is discussed. Their coordinate-space form is presented and analyzed in the static, non-relativistic case.
