Rate-computation optimized block based video coding
Creators: name: Lee, Yuen-Wen
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation reports on rate-distortion optimized and computation-constrained video coding algorithms which yield effective and efficient block-based video encoders. We first propose a new cost function for motion estimation which can achieve good tradeoffs among motion vector bit rate, compensation distortion, and number of computations. Based on the new cost function, we propose a predictive motion estimation algorithm which can effectively determine the size of the search region according to the statistics of the motion field. The proposed motion estimation algorithm allows control of the motion vector bit rate and the computational cost, simultaneously. We also develop two efficient rate-distortion optimized coding mode selection algorithms, based on thresholding and finite state machine (FSM) methods, respectively. The thresholding method can eliminate consideration of the computationally expensive modes. The FSM method determines the test orders of the modes and associated parameters by exploiting the local statistics of the input video sequence. The proposed two methods can reduce substantially the computation requirements as compared to the full search mode selection method. Based on the proposed motion estimation and mode selection algorithms, we implement an H.263-based video coder and an MPEG-2 compliant video coder for very low bit rate video applications, and high bit rate interlaced video applications, respectively. The resulting video coders achieve excellent tradeoffs among bit rate, quality, and computational complexity. In fact, experimental results show that our video coders outperform the best known video coders in terms of compression performance and encoding speed.

description: На основании теоремы Гельмана Фейнмана получены вириальные соотношения для двухэлектронной системы в фононном поле двумерного кристалла. Показано, что в пределе сильной связи для двумерного биполярона выполняется терема , обобщающая известную терему Пекара на системы с кулоновскими взаимодействиями. В отсутствии электронных корреляций, при (где и – статическая и высокочастотная диэлектрические проницаемость соответственно) функционал биполярона распадается на сумму двух поляронных функционалов. При этом теорема переходит в известную теорему Пекара 1:2:3:4 для поляронного функционала сильной связи. Соотношения справедливы для произвольной величины электрон-фононного взаимодействия, в то же время, соотношение выполняется только в пределе сильной связи.

description: В статье приведены результаты выбора оптимального алгоритма поверки фазоизмерительной аппаратуры. Показано, что для получения предельной точности поверки фазоизмерительной аппаратуры необходимо обеспечить не только минимальную погрешность калибратора фазы, но и минимизировать фазовую погрешность доставки сигналов с выходов калибратора фазы до входов поверяемого прибора. Из проведенного анализа алгоритмов поверки следует, что наивысшую точность обеспечивает схема поверки с дополнительным измерительным прибором и развременной одноканальной схемой подключения входов поверяемого фазометра к входам дополнительного измерительно прибора. При рассмотрении структуры дополнительного измерительного прибора предложено использовать гетеродинное преобразование частоты с последующим применением импульсного квантования временных интервалов, пропорциональных искомому сдвигу фаз и периоду исследуемых сигналов.

description: The blazar AO 0235+164 was claimed to show a quasi-periodic behaviour in the radio and optical bands. Moreover, an extra emission component contributing to the UV and soft X-ray flux was detected, whose nature is not yet clear. A predicted optical outburst was observed in late 2006/early 2007. We here present the radio-to-optical WEBT light curves during the outburst, together with UV data acquired by Swift in the same period. We found the optical outburst to be as strong as the big outbursts of the past: starting from late September 2006, a brightness increase of 5 mag led to the outburst peak in February 19-21, 2007. We also observed an outburst at mm and then at cm wavelengths, with an increasing time delay going toward lower frequencies during the rising phase. Cross-correlation analysis indicates that the 1 mm and 37 GHz flux variations lagged behind the R-band ones by about 3 weeks and 2 months, respectively. These short time delays suggest that the corresponding jet emitting regions are only slightly separated and/or misaligned. In contrast, during the outburst decreasing phase the flux faded contemporaneously at all cm wavelengths. This abrupt change in the emission behaviour may suggest the presence of some shutdown mechanism of intrinsic or geometric nature. The behaviour of the UV flux closely follows the optical and near-IR one. By separating the synchrotron and extra component contributions to the UV flux, we found that they correlate, which suggests that the two emissions have a common origin.

description: We discuss the ways that a “difficult” behavior in classroom and at school is possible to be recognized by the participants in the educational proceedings, namely the teacher and the pupil, having “difficult” behavior’s confrontation as a target.According to the social construction theory, the knowledge produced by the cooperation doesn’t transmit from teacher to pupil and the suggested resolutions come from all the participants’ communicational activities during the educational proceedings. The turn to pupils’ discourse allows us not only listening to the children but also giving them “voice”.Thus, the relation is formed not only by the teacher’s request but by the pupil’s too. Generally, the turn to discourse gives us the opportunity to examine the dilemmas constituting the basis for interventions in the interactional context.

description: Optical artificial neural networks (ONNs) have significant potential for ultra-high computing speed and energy efficiency. We report a new approach to ONNs based on integrated Kerr micro-combs that is programmable, highly scalable and capable of reaching ultra-high speeds, demonstrating the building block of the ONN, a single neuron perceptron, by mapping synapses onto 49 wavelengths to achieve a single-unit throughput of 11.9 Giga-OPS at 8 bits per OP, or 95.2 Gbps. We test the perceptron on handwritten-digit recognition and cancer-cell detection, achieving over 90% and 85% accuracy, respectively. By scaling the perceptron to a deep learning network using off the shelf telecom technology we can achieve high throughput operation for matrix multiplication for real-time massive data processing.

Performance evaluation of a modified RACE R2084 ATDMA access system
Creators: name: Chen, Lewis Wai Man
Publisher: name: University of British Columbia
Year: 2009

description: The telecommunications industry is experiencing an unprecedented demand for mobile communication services. It is expected that mobile subsribers will increasingly use multimedia services such as data, voice, and video applications. In this thesis, we study the access mechanism (medium access control (MAC) protocol and bandwidth allocation strategy) used in the RACE R2084 Advanced Time Division Multiple Access (ATDMA) system which focuses on the development of a third generation cellular system known as the Universal Mobile Telecommunication System (UMTS). In particular, we propose improvements to the ATDMA access mechanism which allow the base station to dynamically assign bandwidth to voice and video services based on their activity levels. The performance of the modified access mechanism is evaluated using the access delay and packet dropping probability experienced by the voice and video services under varying traffic-load conditions. For video service, it is shown that the modified access mechanism can increase the ATDMA system capacity by as much as 45% when compared to the original access mechanism. In supporting voice and video traffic simultaneously, simulation results show that the modified access mechanism can increase the system capacity, in general, while satisfying the QoS requirements for both voice and video services.

The induction of ventricular arrhythmias has been achieved via a permanent re-infarction through left anterior descending artery (LAD) ligation one week after a 30-minute ischemia-reperfusion. The time between 2 infarctions gave the stem cells the required period to entgraft themselves after their intramyocardial injection with the first infarction.

description: Conjugated polymers are observed to aggregate in solution. To account for this observation we propose a inter-chain binding mechanism based on the intermolecular tunneling of the delocalized $π$-electrons occurring at points where the polymers cross. This tunneling mechanism predicts specific bound structures of chain that depend on whether they are semiconducting or metallic. Semiconducting chains should form polyacene-like states exhibiting binding at every other site, while (doped) metallic chains can bind at each site. We also show that solitons co-localize with the intermolecular binding sites thereby strengthening the binding effect and investigate the conformational statistics of the resulting bimolecular aggregates.

description: Monte Carlo simulations are presented for a coarse-grained model of real quadrupolar fluids. Molecules are represented by particles interacting with Lennard-Jones forces plus the thermally averaged quadrupole-quadrupole interaction. The properties discussed include the vapor-liquid coexistence curve, the vapor pressure along coexistence, and the surface tension. The full isotherms are also accessible over a wide range of temperatures and densities. It is shown that the critical parameters (critical temperature, density, and pressure) depend almost linearly on a quadrupolar parameter $q=Q^{*4} /T^*$, $Q^*$ is the reduced quadrupole moment of the molecule and $T^*$ the reduced temperature. The model can be applied to a variety of small quadrupolar molecules. We focus on carbon dioxide as a test case, but consider nitrogen and benzene, too. Experimental critical temperature, density and quadrupolar moment are sufficient to fix the parameters of the model. The resulting agreement with experiments is excellent and marks a significant improvement over approaches which neglect quadrupolar effects. The same coarse-grained model was also applied in the framework of Perturbation Theory (PT) in the Mean Spherical Approximation (MSA). As expected, the latter deviates from the Monte Carlo results in the critical region, but is reasonably accurate at lower temperatures.

description: Thin-film lithium niobate is an attractive integrated photonics platform due to its low optical loss and favorable optical nonlinear and electro-optic properties. However, in applications such as second harmonic generation, frequency comb generation, and microwave-to-optics conversion, the device performance is strongly impeded by the photorefractive effect inherent in thin-films. In this paper, we show that the dielectric cladding on lithium niobate microring resonator has a significant influence on the photorefractive effect. By removing the dielectric cladding layer, the photorefractive effect in lithium niobate ring resonators can be effectively mitigated. Our work presents a reliable approach to control the photorefractive effect on thin-film lithium niobate and will further advance the performance of integrated classical and quantum photonic devices based on thin-film lithium niobate.

description: We examine two mechanisms that have been put forward to explain the selection of quasipatterns in single and multi-frequency forced Faraday wave experiments. Both mechanisms can be used to generate stable quasipatterns in a parametrically forced partial differential equation that shares some characteristics of the Faraday wave experiment. One mechanism, which is robust and works with single-frequency forcing, does not select a specific quasipattern: we find, for two different forcing strengths, a 12-fold quasipattern and the first known example of a spontaneously formed 14-fold quasipattern. The second mechanism, which requires more delicate tuning, can be used to select particular angles between wavevectors in the quasipattern.

On the iterative decoding of sparse quantum codes

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We address the problem of decoding sparse quantum error correction codes. For Pauli channels, this task can be accomplished by a version of the belief propagation algorithm used for decoding sparse classical codes. Quantum codes pose two new challenges however. Firstly, their Tanner graph unavoidably contain small loops which typically undermines the performance of belief propagation. Secondly, sparse quantum codes are by definition highly degenerate. The standard belief propagation algorithm does not exploit this feature, but rather it is impaired by it. We propose heuristic methods to improve belief propagation decoding, specifically targeted at these two problems. While our results exhibit a clear improvement due to the proposed heuristic methods, they also indicate that the main source of errors in the quantum coding scheme remains in the decoding.

description: This report describes the authors' experiences in developing and optimising the serial and parallel versions of a very large complex agent-based economic model. The EURACE Model was developed as part of the EU Framework 6 project EURACE using the Flexible Large-scale Agent Modelling Environment - FLAME - which has been developed in a collaboration between the Computer Science Department of the University of Sheffeld and the Software Engineering Group at the STFC Rutherford Appleton Laboratory. The report contains a brief description of FLAME, which is an applications program generator for agent-based simulations and its parallel implementation. However the bulk of the report is concerned with the process of developing and optimising the serial and parallel versions of the EURACE model. This includes a description of the tools developed by the project to aid this development and how they were used in debugging the EURACE Model. The final sections of the report describe some of the large-scale benchmark simula-tions performed with a study of the effects of serial sections on the overall parallel performance of such a model.

description: Η Συνθήκη για την Ευρωπαϊκή Ένωση (ΣΕΕ), γνωστή και ως Συνθήκη του Μάαστριχτ, καθόρισε το χρονοδιάγραμμα ολοκλήρωσης της Οικονομικής και Νομισματικής Ένωσης (ΟΝΕ), καθώς και το θεσμικό πλαίσιο για την άσκηση της μακροοικονομικής πολιτικής της Ευρωπαϊκής Ένωσης. Η νομισματική πολιτική πέρασε από την δικαιοδοσία των κρατών μελών στον νεοσυσταθέντα ανεξάρτητο υπερεθνικό οργανισμό της Ευρωπαϊκής Κεντρικής Τράπεζας (ΕΚΤ), που ανέλαβε την ευθύνη άσκησης ενιαίας νομισματικής πολιτικής. Αντίθετα, η δημοσιονομική πολιτική παρέμεινε στην δικαιοδοσία των κρατών μελών, αλλά ασκείται με βάση προκαθορισμένους κανόνες που θέτει το Σύμφωνο Σταθερότητας και Ανάπτυξης (ΣΣΑ), το αρμόδιο όργανο για το συντονισμό και την επιτήρηση των εθνικών δημοσιονομικών πολιτικών. Η διπλωματική αυτή εργασία έχει δυο στόχους. Πρώτον, να διερευνήσει τις διάφορες πτυχές της ευρωπαϊκής νομισματικής και δημοσιονομικής πολιτικής στα πλαίσια των δυο αυτών θεσμών της ΟΝΕ (ΕΚΤ, ΣΣΑ). Δεύτερον, να αξιολογήσει τη νομισματική και δημοσιονομική πολιτική που άσκησε η ΕΕ για την αντιμετώπιση της σημερινής παγκόσμιας οικονομικής κρίσης, σε αντιπαράθεση με τις αντίστοιχες πολιτικές των ΗΠΑ.
description: The Treaty of the European Union, known as Maastricht Treaty, determined the timetable of the Economic and Monetary Unit’s (EMU) completion, as well as the institutional framework for the exertion of the European’s Union macroeconomic policy. The monetary policy passed from the Member States jurisdiction over the independent supranational organization of the European Central Bank (ECB), who undertook the responsibility for the exertion of united monetary policy. On the contrary, the fiscal policy remained in the Member’s States jurisdiction, but is exerted based on default rules, which pose the Stability and Growth Pact (SGP), the competent instrument for the coordination and the surveillance of the national fiscal policy. The aim of this thesis is, firstly, to examine all the different aspects of the European Monetary and Fiscal policy in the frame of these two institution (ECB, SGP) and, secondly to appreciate the monetary and fiscal policy which the European Union exerted for the confrontation of today’s global economic crisis, contrary the policies of the USA.

description: This chapter describes the relationship between low frequency noise and coherence decay of localized spins in semiconductors. Section 2 establishes a direct relationship between an arbitrary noise spectral function and spin coherence as measured by a number of pulse spin resonance sequences. Section 3 describes the electron-nuclear spin Hamiltonian, including isotropic and anisotropic hyperfine interactions, inter-nuclear dipolar interactions, and the effective Hamiltonian for nuclear-nuclear coupling mediated by the electron spin hyperfine interaction. Section 4 describes a microscopic calculation of the nuclear spin noise spectrum arising due to nuclear spin dipolar flip-flops with quasiparticle broadening included. Section 5 compares our explicit numerical results to electron spin echo decay experiments for phosphorus doped silicon in natural and nuclear spin enriched samples.

Using unitary transforms for MPEG block motion estimation
Creators: name: Cavén, Ian Roger
Publisher: name: University of British Columbia
Year: 2009

description: Block motion estimation, a stage of the MPEG video encoding process which significantly effects the quality and bit rate of an encoded video sequence, is also the most computation intensive part of the encoding process. To reduce the number of operations in this step, it is proposed that unitary transforms may be used to create condensed versions of the data, called block signatures, which can be used in place of the original video data during the matching process. Continuing previous work, this thesis studies several unitary transforms for their utility in creating signatures with the desired properties, with the focus being on how to select and allocate bits to the transform coefficients, and it considers the efficient computation of these signatures. Hardware and software implementations incorporating these signatures are suggested and discussed, and the results of implementing two proposed signature matching algorithms are described. A signature composed of sixty-four discrete cosine transform coefficients was found to work well in a full-search matching scheme appropriate for hardware implementation. The other proposed signature matching algorithm, which attempts to minimise the difference between the coefficients one at a time during the search for matches, performed poorly since the transform coefficients with most of the energy in the signal also tend contain most of the energy in the prediction error as well, and therefore the differences between these higher energy coefficients can not be minimised too early in the search process. Further work is needed to determine if a joint minimisation of differences between the transform coefficients of a target block and the set of available matches would be effective.

description: The orbital magnetic moment of a Co adatom on a Pt(111) surface is calculated in good agreement with experimental data making use of the LSDA+U method. It is shown that both electron correlation induced orbital polarization and structural relaxation play essential roles in orbital moment formation. The microscopic origins of the orbital moment enhancement are discussed.

description: Two-dimensional layered trichalcogenide materials have recently attracted the attention of the scientific community because of its robust mechanical, thermal properties and applications in opto and nanoelectronics devices. We report the pressure dependence of out-of plane Ag Raman modes in high quality few-layers titanium trisulfide (TiS3) nanoribbons grown using a direct solid-gas reaction method and infer their cross-plane thermal expansion coefficient.Both mechanical stability and thermal properties of the TiS3 nanoribbons are elucidated using phonon-spectrum analyses. Raman spectroscopic studies at high pressure (up to 34 GPa) using a diamond anvil cell identify four prominent Ag Raman bands; a band at 557 cm-1 softens under compression, and others at 175, 300, and 370 cm-1 show normal hardening. Anomalies in phonon mode frequencies and excessive broadening in line-width of the soft phonon about ~ 13 GPa are attributed to the possible onset of a reversible structural transition. A complete structural phase transition at 43 GPa is inferred from Ag soft mode frequency (557 cm-1) versus pressure extrapolation curve, consistent with recent reported theoretical predictions. Using the experimental mode Grüneisen parameters i of Raman modes, the cross-plane thermal expansion coefficient Cv of the TiS3 nanoribbons at ambient phase is estimated to be1.32110-6K-1. The observed results are expected to be useful in calibration and performance of next generation nano-electronics and optical devices under extreme stress conditions.

description: A class of diffusion driven Free Boundary Problems is considered which is characterized by the initial onset of a phase and by an explicit kinematic condition for the evolution of the free boundary. By a domain fixing change of variables it naturally leads to coupled systems comprised of a singular parabolic initial boundary value problem and a Hamilton-Jacobi equation. Even though the one dimensional case has been thoroughly investigated, results as basic as well-posedness and regularity have so far not been obtained for its higher dimensional counterpart. In this paper a recently developed regularity theory for abstract singular parabolic Cauchy problems is utilized to obtain the first well-posedness results for the Free Boundary Problems under consideration. The derivation of elliptic regularity results for the underlying static singular problems will play an important role.

description: Hard magnetic materials belong to a novel class of soft active materials with the capability of quick, large, and complex deformation via applying an external actuation. They have an extensive range of potential applications in soft robots, biomedical devices, and stretchable electronics, etc. Recently, investigation on the experimental and theoretical nonlinear mechanics of hard magnetic soft cantilevers has received notable considerations. In the available analyses, the most attention was paid to the non-bifurcation-type nonlinear mechanics of the system, and bifurcation was considered for a specific case. In the current study, the general trend of bifurcation-type nonlinear mechanics of hard magnetic soft cantilevers is introduced and the effective parameters on the occurrence of bifurcation are identified. Additionally, new trajectories due to the bifurcation and the corresponding workspace are presented. Eventually, a comprehensive comparative study between the new trajectories and workspace with those reported in the prior studies is carried out.

title: On the evaluation complexity of cubic regularization methods for potentially rank-deficient nonlinear least-squares problems and its relevance to constrained nonlinear optimization

description: We propose a new termination criteria suitable for potentially singular, zero or non-zero residual, least-squares problems, with which cubic regularization variants take at most O(epsilon−3/2) residual- and Jacobian-evaluations to drive either the residual or a scaled gradient of the least-squares function below epsilon; this is the best-known bound for potentially singular nonlinear least-squares problems. We then apply the new optimality measure and cubic regularization steps to a family of least-squares merit functions in the context of a target-following algorithm for nonlinear equality-constrained problems; this approach yields the first evaluation complexity bound of order epsilon−3/2 for nonconvexly constrained problems when higher accuracy is required for primal feasibility than for dual first-order criticality.

description: Topological spin textures have attracted much attention both for fundamental physics and spintronics applications. Among them, antiskyrmions possess a unique spin configuration with Bloch-type and Néel-type domain walls due to anisotropic Dzyaloshinskii-Moriya interaction (DMI) in the noncentrosymmetric crystal structure. However, antiskyrmions have thus far only been observed in a few Heusler compounds with $D_{2\mathrm{d}}$ symmetry. Here, we report a new material Fe$_{1.9}$Ni$_{0.9}$Pd$_{0.2}$P in a different symmetry class ($S_4$ symmetry), where antiskyrmions exist over a wide temperature region including room temperature, and transform to skyrmions upon changing magnetic field and lamella thickness. The periodicity of magnetic textures greatly depends on crystal thickness, and domains with anisotropic sawtooth fractals are observed at the surface of thick crystals, which are attributed to the interplay between dipolar interaction and DMI as governed by crystal symmetry. Our findings provide a new arena to study antiskyrmions, and should stimulate further research on topological spin textures and their applications.
