description: We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is comprised of two orthogonal discs, one of which contains old stars (old stellar disc), and the other, containing both younger stars and the cold gas (polar disc) of the galaxy. By exploring the shape of the inner region of the dark matter halo, we are able to confirm that the halo shape is a oblate ellipsoid flattened in the direction of the polar disc. We also note that there is a twist in the shape profile, where the innermost 3 kpc of the halo flattens in the direction perpendicular to the old disc, and then aligns with the polar disc out until the virial radius. This result is then compared to the halo shape inferred from the circular velocities of the two discs. We also use the temporal information of the simulation to track the system's evolution, and identify the processes which give rise to this unusual galaxy type. We confirm the proposal that the polar disc galaxy is the result of the last major merger, where the angular moment of the interaction is orthogonal to the angle of the infalling gas. This merger is followed by the resumption of coherent gas infall. We emphasise that the disc is rapidly restored after the major merger and that after this event the galaxy begins to tilt. A significant proportion of the infalling gas comes from filaments. This infalling gas from the filament gives the gas its angular momentum, and, in the case of the polar disc galaxy, the direction of the gas filament does not change before or after the last major merger.

description: We study higher level Regge resonances of open superstrings, focusing on the universal part of the Neveu-Schwarz sector common to all D-brane realizations of the standard model. For Regge states with masses far above the fundamental string scale, we discuss the spin-dependence of their decay rates into massless gauge bosons. Extending our previous work on lowest level string excitations, we study the second mass level at which spins range from 0 to 3. We construct the respective vertex operators and compute the amplitudes involving one massive particle and two or three gauge bosons. To illustrate the use of BCFW recursion relations in superstring theory, we build the four gluon amplitude from on-shell amplitudes involving string resonances and gauge bosons.

description: Electron capture and positron decay rates are calculated for neutron-deficient Kr and Sr waiting point nuclei in stellar matter. The calculation is performed within the framework of pn-QRPA model for rp-process conditions. Fine tuning of particle-particle, particle-hole interaction parameters and a proper choice of the deformation parameter resulted in an accurate reproduction of the measured half-lives. The same model parameters were used to calculate stellar rates. Inclusion of measured Gamow-Teller strength distributions finally led to a reliable calculation of weak rates that reproduced the measured half-lives well under limiting conditions. For the rp-process conditions, electron capture and positron decay rates on $^{72}$Kr and $^{76}$Sr are of comparable magnitude whereas electron capture rates on $^{78}$Sr and $^{74}$Kr are 1--2 orders of magnitude bigger than the corresponding positron decay rates. The pn-QRPA calculated electron capture rates on $^{74}$Kr are bigger than previously calculated. The present calculation strongly suggests that, under rp-process conditions, electron capture rates form an integral part of weak-interaction mediated rates and should not be neglected in nuclear reaction network calculations as done previously.

description: The two levels of data and actions on those data provided by the separation between equations and rules in rewriting logic are completed by a third level of strategies to control the application of those actions. This level is implemented on top of Maude as a strategy language, which has been successfully used in a wide range of applications. First we summarize the Maude strategy language design and review some of its applications; then, we describe a new case study, namely the description of completion procedures as transition rules + control, as proposed by Lescanne.

Reduced-dimensional modelling of CSF flow in the brain

description: Talk at University of Florida, Seminar on Applied and Numerical Analysis, 7th of April 2022. Abstract: Our brain uses approximately 20% of the body’s energy in resting state.
 Yet the brain lacks a traditional lymphatic system for metabolic clearance. This
 raises the question of how the brain clears waste. This question is of key
 importance as several neurological diseases, such as Alzheimer’s and Parkinson’s
 disease, are characterised by the accumulation of toxic proteins in the brain.
 According to the glymphatic theory, cerebrospinal fluid (CSF) flows in a network
 of perivascular spaces surrounding the arteries of the brain. This allows for a bulk
 flow of CSF through the brain that can remove metabolic waste. There are,
 however, several unanswered questions regarding the physical processes that are at
 work. For example it is unclear what the driving force of this flow is. In order to
 assess these questions we need to develop models for glymphatic fluid flow. One
 of the challenges of such a model is that the glymphatic network is highly
 complex, making it intractable to resolve as a 3D geometry.
 In this talk, we consider 3D Stokes flow in the annular spaces surrounding blood
 vessels. The domain is allowed to move in order to take into account arterial
 pulsations. Assuming the flow behaves like annular Poiseuille flow, we then
 reduce this to a 1D network equation. We show that the reduced model captures
 the key features of the full 3D model at a fraction of the runtime and computational
 cost.

description: In this paper, we study variants of the canonical Local-Hamiltonian problem where, in addition, the witness is promised to be separable. We define two variants of the Local-Hamiltonian problem. The input for the Separable-Local-Hamiltonian problem is the same as the Local-Hamiltonian problem, i.e. a local Hamiltonian and two energies a and b, but the question is somewhat different: the answer is YES if there is a separable quantum state with energy at most a, and the answer is NO if all separable quantum states have energy at least b. The Separable-Sparse-Hamiltonian problem is defined similarly, but the Hamiltonian is not necessarily local, but rather sparse. We show that the Separable-Sparse-Hamiltonian problem is QMA(2)-Complete, while Separable-Local-Hamiltonian is in QMA. This should be compared to the Local-Hamiltonian problem, and the Sparse-Hamiltonian problem which are both QMA-Complete. To the best of our knowledge, Separable-SPARSE-Hamiltonian is the first non-trivial problem shown to be QMA(2)-Complete.
Signal design for MIMO-OFDM systems

Publisher: name: University of British Columbia
Year: 2010

description: Orthogonal frequency division multiplexing (OFDM) combined with multiple-input multiple-output (MIMO) wireless technology is an attractive air-interface solution for wireless systems. The time-selective and dispersive nature of the wireless channel, however, poses challenges for signal design. To address these challenges, this dissertation investigates several physical layer aspects of signal design for MIMO-OFDM systems. To improve the information outage rate of certain MIMO systems with low-rank channel matrices, we propose two novel channel augmentation schemes, namely, the complex virtual antenna (CVA) and the real virtual antenna (RVA) schemes. For Bell labs space-time (BLAST) type architectures, both the CVA and the RVA schemes are more robust to channel correlations than a previously proposed scheme. For performance enhancement of coded MIMO-OFDM, we consider wrapped space-frequency coding (WSFC) and coded vertical BLAST (V-BLAST) with adaptive bit loading (ABL) and optimize both schemes. We show that bit-loaded WSFC and V-BLAST optimized for coded MIMO-OFDM can achieve error rate performances close to that of quasi-optimal MIMO-OFDM based on single value decomposition (SVD) of the channel, while their feedback requirements for loading are low. To exploit the spatial and frequency diversity in coded MIMO-OFDM systems, we propose cyclic space-frequency (CSF) filtering, which is applicable to both traditional MIMO systems with co-located transmit antennas and cooperative diversity systems with distributed transmit antennas. We further propose a robust CSF filtering scheme, which exploits imperfect channel state information at the transmitter (CSIT) and takes into account the reliability of the CSIT. To further improve robustness, we combine CSF filtering with space-time block coding (STBC) in the frequency domain. We also propose a linear prediction method for improving the quality of the CSIT via post-processing. For these CSF filtering schemes, design criteria are derived, closed-form solutions are given for certain special cases, and various design methods are provided for the general case. Simulation results confirm that robust CSF filtering is a promising solution for wireless communication systems.

It considers the impact of gas drag effects on particle segregation phenomena and gives details about particle behaviors under various conditions. It extends the 3D sector model to a comprehensive blast furnace model to help improve predictability and reliability in the industry operations.

Compressed sensing : decoding and quantization
Creators: name: Saab, Rayan
Publisher: name: University of British Columbia
Year: 2010

description: Recently, great strides in sparse approximation theory and its application have been made. Many of these developments were spurred by the emerging area of compressed sensing. Compressed sensing is a signal acquisition paradigm that entails recovering estimates of sparse and compressible signals from n linear measurements, many fewer than the signal ambient dimension N. In general, these measurements are assumed to be imperfect. For example, they may be noisy or quantized (or both). Thus, the associated sparse recovery problem requires the existence of stable and robust “decoders” to reconstruct the signal. In this thesis, we first address the theoretical properties of ∆p, a class of compressed sensing decoders that rely on ℓp minimization with p ∈ (0, 1). In particular, we extend the known results regarding the decoder ∆₁, based on ℓ₁ minimization, to ∆p with p ∈ (0, 1). Our results are two-fold. We show that under sufficient conditions that are weaker than the analogous sufficient conditions for ∆₁, the decoders ∆p are robust to noise and stable. In particular, they are (2, p) instance optimal. We also show that, like ∆₁, the decoders ∆p are (2, 2) instance optimal in probability provided the measurement matrix is drawn from an appropriate distribution. Second, we address quantization of compressed sensing measurements. Typically, the most commonly assumed approach (called PCM) entails quantizing each measurement independently, using a quantization alphabet with step-size d. Subsequently, by using a stable and robust decoder one can guarantee that the estimate produced by the decoder is within O(d) of the signal. As a more effective alternative, we propose using sigma-delta schemes to quantize compressed sensing measurements of a k-sparse signal. We show that there is an associated two-stage recovery method which guarantees a reduction of the approximation error by a factor of (n/k){α(r−¹/²)}, for any α < 1 if n ≳ k(log N)¹{¹−α)} (with high probability on the initial draw of the measurement matrix). In particular, the first recovery stage employs a stable decoder to estimate the support of the signal, while the second stage employs Sobolev dual frames to approximate the signal.

description: Associative polymer solutions belong to a special class of polymers that can form physical gels and networks. These polymer solutions are used in a wide variety of products and applications such paints, food thickeners, adhesives, bio-medical implants and many such more. Understanding the static and dynamic properties of these polymer solutions at equilibrium and in flow are important to design many such products. In this thesis we have developed a simulation method to investigate and predict different properties of associative polymer solutions which will help to efficiently design and manufacture products involving these polymers.

description: Li-ion batteries are ubiquitous in today’s world with portable electronics, EVs making inroads into daily lives, and electric aircraft at the cusp of becoming reality. These and many more applications revolutionize the world with improvements in batteries at scales from materials, manufacturing, electrode architectures, cell design, and protocols. The various challenges associated with the current generation of batteries include the fast-charging capabilities, economic return of the longevity of the battery, and thermal safety characteristics. The aging and degradation of LIBs appears to be a key pain point particularly when exposed to harsh operating temperature and fast charging conditions. LIBs undergo aging due to numerous chemical and physical degradation processes throughout their lifetime owing to their operation. These challenges are exacerbated by the presence of stringent operating conditions including extreme fast charging, and sub-zero temperature resulting in severe degradation and short cycle life. The LIBs also face challenges in their thermal stability characteristics, failing catastrophically when exposed to high temperature or mechanical abuse conditions. The onset and intensity of these thermal runaway behaviors are further modified when batteries undergo varied aging leading to increased heat and gas generation potentially causing fire or explosions. Overall, a comprehensive characterization to delineate the interconnected role and implications of operating extremes and electrode design on electrochemical performance, cell aging, and thermal runaway behavior is critical for better batteries. To this end, the role of electrode microstructure in mitigating lithium plating behavior under various operating conditions, including extreme fast charging has been examined. Further, these multi-length scale characteristics of the electrode microstructure are explored via data-driven approaches to study the complex interaction of transport and kinetic limitations on the microstructure designs. A third study is undertaken for in-operando characterization of the LIB degradation, probing the multi-length scale degradation using pulse voltammetry. Here an accurate degradation descriptors dataset is identified and accurately parametrized, throughout its cycling lifespan. These aging behaviors are translated to physio-chemical degradation mechanisms via a reduced-order coupled electrochemical-thermal-aging interactions model. Lastly, the implication of aging behavior on thermal-safety interactions is delineated. Overall the dissertation is focused on developing a fundamental understanding of the LIB performance, degradation, and safety interactions.

description: This thesis aims to upgrade the pyrolytic bio-vapours at 300-600C. We used scrap tyre char as catalysts first, because it is rich in Zn and S which are commonly used as catalysts in the biomass conversion process. Our concept was proved that tyre char can selectively crack the bio-vapours into smaller oxygenates, especially furfural. To study the catalytic mechanism, we tested different model compounds and modified tyre char catalysts. We found ZnSO4 is the strongest acidic active site compared to ZnS and ZnO. Based on these findings, we used pure ZnSO4 and Pd-modified ZnSO4 to get a higher furfural selectivity.

description: Chromatin is a long polymer made of DNA and proteins; its four-dimensional (spatial and temporal) organisation is crucial in regulating cellular processes like transcription, replication and DNA repair. How the chromatin self-organises spatially and temporally is a question of active research. In this thesis, we discuss computational studies to predict the 3D organisation of chromatin, given experimentally measured contact probability (3C, 5C and Hi-C) data. We have developed an inverse Brownian dynamics method that can compute the chromatin organisation. We also investigate the dynamics of chromatin on the length scale of a domain.

description: A microencapsulation strategy of active food components via spray drying to improve their bioaccessibility and targeted release was proposed. A typical dairy protein, whey protein isolate, was used to encapsulate vitamin B2 and curcumin, with ethanol desolvation and calcium crosslinking of proteins to modify release properties during digestion. The spray-dried microparticles were incorporated into yogurt and evaluated in a near-real dynamic in vitro human stomach. The outcomes suggested that the release of active ingredients upon digestion of food depended on the physiological process of gastric emptying.

description: The 21st century has seen a renewed interest in developing Canadian Arctic oil and gas reserves. Historically, hydrocarbon development efforts focused on land or shallow water hydrocarbon potential. Since 2008 the industry has shifted its attention to the deepwater areas of the Canadian Beaufort Sea — a region that to date has experienced limited exploration and no development. In the wake of the huge Macondo oil spill in the Gulf of Mexico, Canada's National Energy Board (NEB) initiated a public Review of Offshore Drilling in the Canadian Arctic to ensure the regulatory system was prepared to handle the unique challenges of Arctic drilling. There was no similar examination of the adequacy and appropriateness of Canada's Arctic oil and gas rights issuance process. In this paper we argue that a key weakness in the current procedure is the failure of the government to apply state of the art Strategic Environmental Assessments (SEAs) as part of deciding where and when to open new areas to potential oil and gas drilling activities.

description: Large-scale arrays of Microwave Kinetic Inductance Detectors (MKIDs) are attractive candidates for use in imaging instruments for next generation submillimeter-wave telescopes such as CCAT. We have designed and fabricated tightly packed ~250-pixel MKID arrays using lumped-element resonators etched from a thin layer of superconducting TiNx deposited on a silicon substrate. The high pixel packing density in our initial design resulted in large microwave crosstalk due to electromagnetic coupling between the resonators. Our second design eliminates this problem by adding a grounding shield and using a double-wound geometry for the meander inductor to allow conductors with opposite polarity to be in close proximity. In addition, the resonator frequencies are distributed in a checkerboard pattern across the array. We present details for the two resonator and array designs and describe a circuit model for the full array that predicts the distribution of resonator frequencies and the crosstalk level. We also show results from a new experimental technique that conveniently measures crosstalk without the need for an optical setup. Our results reveal an improvement in crosstalk from 57% in the initial design down to \leq 2% in the second design. The general procedure and design guidelines in this work are applicable to future large arrays employing microwave resonators.

description: The climate impact of liquefied natural gas (LNG) export from North America is one of the most pressing questions for Canadian and world energy policy today. This paper performs the first life cycle assessment (LCA) of the greenhouse gas emissions from LNG exports from Canada, assuming that importing countries use the natural gas for electricity generation. It shows that the climate impact of LNG depends on where it is sent. If LNG from Canada displaces electricity in coal-dependent countries, it will likely lower global greenhouse gas emissions. If it displaces electricity from countries that rely on low carbon sources such as hydroelectricity and nuclear power, it will likely increase global emissions. A broad suite of policy and regulatory measures is discussed for reducing greenhouse gas emissions due to LNG export, from life cycle regulation to facility-level emissions management.

description: Coal is one of the biggest commercial fuel all over the world. Fly ash, a coal combustion by-product, is consequently produced. This project is focused on the synthesis of Fe- and Mg-based nanomaterials from Victorian brown coal fly ash and the applications to water remediation and water gas shift reaction. Additionally, this research is expected to address the global environmental challenge facing the industrial solid waste: how to utilize the coal fly ash waste in a value-added strategy, which is a pivotal trend in sustainable development.
Biodiversity and Conservation Offsets: A Guide for Albertans

conservation

description: The purpose of this paper is to introduce Albertans to one of these new tools, conservation offsets. Under an offset system the negative environmental impacts of land or resource development may be compensated for by the intentional creation of corresponding positive impacts. This paper describes this tool and the approach that Alberta is taking in policy development respecting offsets. It also offers some comments on the strengths and weaknesses of the approach Alberta is taking.

description: The variation in sizes of chondrules from one chondrite to the next is thought to be due to some sorting process in the early solar nebula. Hypotheses for the sorting process include chondrule sorting by mass and sorting by some aerodynamic mechanism; one such aerodynamic mechanism is the process of turbulent concentration (TC). We present the results of a series of statistical tests of chondrule data from several different chondrites. The data do not clearly distinguish between various options for the sorting parameter, but we find that the data are inconsistent with being drawn from lognormal or (three-parameter) Weibull distributions in chondrule radius. We also find that all but one of the chondrule data sets tested are consistent with being drawn from the TC distribution.

3D-TV Content generation and multi-view video coding

description: The success of the 3D technology and the speed at which it will penetrate the entertainment market will depend on how well the challenges faced by the 3D-broadcasting system are resolved. The three main 3D-broadcasting system components are 3D content generation, 3D video transmission and 3D display. One obvious challenge is the unavailability of a wide variety of 3D content. Thus, besides generating new 3D-format videos, it is equally important to convert existing 2D material to the 3D format. This is because the generation of new 3D content is highly demanding and in most cases, involves post-processing correction algorithms. Another major challenge is that of transmitting a huge amount of data. This problem becomes much more severe in the case of multiview video content. This thesis addresses three aspects of the 3D-broadcasting system challenges. Firstly, the problem of converting 2D acquired video to a 3D format is addressed. Two new and efficient methods were proposed, which exploit the existing relationship between the motion of objects and their distance from the camera, to estimate the depth map of the scene in real-time. These methods can be used at the transmitter and receiver-ends. It is especially advantageous to employ them at the receiver-end since they do not increase the transmission bandwidth requirements. Performance evaluations show that our methods outperform the other existing technique by providing better depth approximation and thus a better 3D visual effect. Secondly, we studied one of the problems caused by unsynchronized zooming in stereo-camera video acquisition. We developed an effective algorithm for correcting unsynchronized zoom in 3D videos. The proposed scheme finds corresponding pairs of pixels between the left and right views and the relationship between them. This relationship is used to estimate the amount of scaling and translation needed to align the views. Experimental results show our method produces videos with negligible scale difference and vertical parallax. Lastly, the transmission of 3D-content problem is addressed and two schemes for multiview video coding (MVC) are proposed. While both methods outperform the current MVC standard, one of them introduces significantly less random access delay compared to the MVC standard.
New mechanism for generating spin transfer torque without charge current

description: A new physical mechanism for generating spin-transfer torque is proposed. It is due to interference of bias driven nonequilibrium electrons incident on a switching junction with the electrons reflected from an insulating barrier inserted in the junction after the switching magnet. It is shown using the rigorous Keldysh formalism that this new out-of-plane torque $T_{\perp}$ is proportional to an applied bias and is as large as the torque in a conventional junction generated by a strong charge current. However, the charge current and the in-plane torque $T_{\parallel}$ are almost completely suppressed by the insulating barrier. This new junction thus offers the highly applicable possibility of bias-induced switching of magnetization without charge current.

description: Improved batteries are the centrepiece to enabling continuous usage of electricity derived from intermittent sources. New battery chemistries such as Lithium-Sulfur (Li-S) systems are attractive due to their potential 10-fold increase in gravimetric capacity when compared to existing Lithium-ion technology, but suffer from a lack of cycling stability, in part due to incomplete reduction of sulfur, and polysulphides consequently blocking pores of separator. In this dissertation, we explored polymer-based separators with anti-aging effect and functionalized porous interlayers to encapsulated and retard these polysulfide species. The outcome of this dissertation opens up a new avenue to develop novel membrane based platform for responsive membranes in battery technology development.

description: In this paper, we consider a single-cell IEEE 802.16 environment in which the base station allocates subchannels to the subscriber stations in its coverage area. The subchannels allocated to a subscriber station are shared by multiple connections at that subscriber station. To ensure the Quality of Service (QoS) performances, two Connection Admission Control (CAC) mechanisms, namely, threshold-based and queue-aware CAC mechanisms are considered at a subscriber station. A queuing analytical framework for these admission control mechanisms is presented considering Orthogonal Frequency Division Multiple Access (OFDMA) based transmission at the physical layer. Then, based on the queuing model, both the connection-level and the packet-level performances are studied and compared with their analogues in the case without CAC. The connection arrival is modeled by a Poisson process and the packet arrival for a connection by Batch Markov Arrival Process (BMAP). We determine analytically and numerically different QoS performance measures (connection blocking probability, average number of ongoing connections, average queue length, packet dropping probability, queue throughput and average packet delay).
