description: The demand for more developed and agile urban taxi drones is increasing rapidly nowadays to sustain crowded cities and their traffic issues. The critical factor for spreading such technology could be related to the safety criteria that must be considered. One of the most critical safety aspects for such vertical and/or Short Take-Off and Landing (V/STOL) drones is related to safety during the landing stage, in which most of the recent flight accidents have occurred. This paper focused on solving this issue by proposing decentralized processing cores that could improve the landing failure rate by depending on a Fuzzy Logic System (FLS) and additional Digital Signal Processing (DSP) elements. Also, the proposed system will enhance the safety factor during the landing stages by adding a self-awareness feature in case a certain sensor malfunction occurs using the proposed Adaptive Prognostic Malfunction Unit (APMU). This proposed coarse-grained Autonomous Landing Guidance Assistance System (ALGAS4) processing architecture has been optimized using different optimization techniques. The ALGAS4 architecture has been designed completely using VHDL, and the targeted FPGA was the INTEL Cyclone V 5CGXFC9D6F27C7 chip. According to the synthesis findings of the INTEL Quartus Prime software, the maximum working frequency of the ALGAS4 system is 278.24 MHz. In addition, the proposed ALGAS4 system could maintain a maximum computing performance of approximately 74.85 GOPS while using just 166.56 mW for dynamic and I/O power dissipation.

High-frequency financial data modelling with hybrid marked point processes
Creators: name: Morariu-Patrichi, Maxime
Publisher: name: Imperial College London
Year: 2018

description: The rise of electronic order-driven financial markets has brought a profusion of new high-frequency data to study, with an opportunity to understand the price formation mechanism at the smallest timescales. The original motivation of this thesis is to find a stochastic process that provides an accurate statistical dynamic description of this new data. A critical analysis of the literature reveals a dichotomy between two main sorts of model, Hawkes processes and continuous-time Markov chains, each having qualities that the other lacks. In particular, models of the former sort are successful at capturing excitation effects between different event types but fail to incorporate the state of the market. We resolve this dichotomy by introducing state-dependent Hawkes processes, an extension of Hawkes processes where events can now interact with an auxiliary state process. These new stochastic processes provide us with the first model that features both excitation effects and an explicit feedback loop between events and the state of the market. The application of this new model to high-quality data demonstrates that the excitation effects are indeed strongly state-dependent. State-dependent Hawkes processes come however with theoretical challenges: under which conditions do they exist, are they unique and do not explode? To answer these questions, we view state-dependent Hawkes processes as ordinary point processes of higher dimension, which we then generalise to the class of hybrid marked point processes. This class provides a framework that unifies and extends the existing high-frequency models. Since hybrid marked point processes are defined implicitly via their intensity, one can address the above questions by studying instead a Poisson-driven stochastic differential equation (SDE). We are able to solve this SDE under general assumptions that dispense with the Lipchitz condition usually required in the literature, which yields, as a corollary, the existence and uniqueness of non-explosive state-dependent Hawkes processes.
Choiceless Computation and Symmetry: Limitations of Definability

description: The search for a logic capturing PTIME is a long standing open problem in finite model theory. One of the most promising candidate logics for this is Choiceless Polynomial Time with counting (CPT). Abstractly speaking, CPT is an isomorphism-invariant computation model working with hereditarily finite sets as data structures. While it is easy to check that the evaluation of CPT-sentences is possible in polynomial time, the converse has been open for more than 20 years: Can every PTIME-decidable property of finite structures be expressed in CPT? We attempt to make progress towards a negative answer and show that Choiceless Polynomial Time cannot compute a preorder with colour classes of logarithmic size in every hypercube. The reason is that such preorders have super-polynomially many automorphic images, which makes it impossible for CPT to define them. While the computation of such a preorder is not a decision problem that would immediately separate P and CPT, it is significant for the following reason: The so-called Cai-Fürer-Immerman (CFI) problem is one of the standard benchmarks for logics and maybe best known for separating fixed-point logic with counting (FPC) from P. Hence, it is natural to consider this also a potential candidate for the separation of CPT and P. The strongest known positive result in this regard says that CPT is able to solve CFI if a preorder with logarithmically sized colour classes is present in the input structure. Our result implies that this approach cannot be generalised to unordered inputs. In other words, CFI on unordered hypercubes is a PTIME-problem which provably cannot be tackled with the state-of-the-art choiceless algorithmic techniques.

description: We observe interlaced square vortex lattices in rotating two-component dilute-gas Bose-Einstein condensates (BEC). After preparing a hexagonal vortex lattice in a single-component BEC in an internal state $|1>$ of $^{87}$Rb atoms, we coherently transfer a fraction of the superfluid to a different internal state $|2>$. The subsequent evolution of this pseudo-spin-1/2 superfluid towards a state of offset square lattices involves an intriguing interplay of phase-separation and -mixing dynamics, both macroscopically and on the length scale of the vortex cores, and a stage of vortex turbulence. Stability of the square lattice structure is confirmed via the application of shear perturbations, after which the structure relaxes back to the square configuration. We use an interference technique to show the spatial offset between the two vortex lattices. Vortex cores in either component are filled by fluid of the other component, such that the spin-1/2 order parameter forms a Skyrmion lattice.

Exploring semi-solid alloy deformation with discrete element method simulations and synchrotron radiography
Creators: name: Su, Te-Cheng
Publisher: name: Imperial College London
Year: 2018

description: Semi-solid alloys are deformed in a wide range of pressurised casting processes; an improved understanding and modelling capability are required to minimise defect formation and optimise productivity. This thesis combines thin-sample in-situ X-ray radiography of semisolid Al-Cu alloy deformation with 2D coupled lattice Boltzmann method – discrete element method (LBM-DEM) simulations. Mechanisms of strain heterogeneity and localisation are identified during semi-solid deformation in globular Al-Cu alloys with various combinations of initial solid fraction and strain rates. The calibrated set of LBM-DEM simulations is then used to obtain information that is not available in X-ray imaging to extract deeper insights into the semi-solid deformation behaviours observed in the experiments. It is found that the local contraction and dilation of the percolating grain assembly are highly influenced by the initial solid fraction. When deforming a low solid fraction alloy, macroscopic contraction due to grains being pushed together increases the local liquid pressure and expels liquid from the sample surface. In contrast, deforming high solid fraction alloys leads to macroscopic shear-induced dilation by grains pushing each other apart and surface menisci are sucked-in due to the decrease in interstitial liquid pressure. It is also shown that the macroscopic behaviour of semi-solid alloy deformation undergoes a range of rheological transitions with increasing solid fraction. First from a suspension to a percolating solid network and, later, from net dilation to shear cracking. These transitions are investigated with LBM-DEM simulations, and the transition to shear cracking is shown to be related to the local decrease in interstitial liquid pressure caused by shear-induced dilation. The verified coupled LBM-DEM simulation is shown to exhibit a load:deformation response consistent with the critical state framework of soil mechanics, indicating that this approach can be useful for modelling thermomechanics in casting processes.

En effet, le juriste fribourgeois, très attaché à sa ville, devient rapidement conseiller communal tout en occupant le poste de collaborateur diplomatique du chef du Département politique fédéral, à l’époque le conseiller fédéral Pierre Graber. Propulsé au coeur de la politique étrangère suisse, le jeune diplomate Nordmann va faire ses premières armes à l’étranger en 1980, à la Mission suisse à New York, puis dans son premier poste d’ambassadeur en Amérique centrale, à Guatemala-City, avant de revenir en Europe, à l’UNESCO à Paris. Sa carrière se place donc très tôt sous le signe du multilatéralisme, ce que confirment ses affectations suivantes, qui le montrent également appelé à diriger d’importantes missions bilatérales. Il prend la tête de la Direction des organisations internationales en 1992, puis devient ambassadeur au Royaume-Uni, à l’ONU à Genève et enfin de nouveau à Paris, à l’ambassade cette fois.
Les mémoires de François Nordmann constituent ainsi un aperçu exceptionnel de la vie d’un diplomate qui s’est engagé sans relâche pour défendre la place de la Suisse dans les instances multilatérales.
Decoupling capacitor design issues in 90nm CMOS
Creators: name: Meng, Xiongfei
Publisher: name: University of British Columbia
Year: 2010

description: On-chip decoupling capacitors (decaps) are widely used to reduce power supply noise. Typically, designs use NMOS decaps between standard-cell blocks and NMOS+PMOS decaps within the blocks. Starting at the 90nm CMOS technology node, the traditional decap designs may no longer be suitable due to increased concerns regarding thin-oxide gate leakage and electrostatic discharge (ESD) reliability. This thesis investigates new decap design approaches that address gate leakage and ESD. A cross-coupled design is described that has been recently introduced by cell library developers to handle ESD problems. Three modifications of the cross-coupled design are introduced here and the tradeoffs among transient response, gate leakage and ESD performance are analyzed. The modifications offer designers greater flexibility in decoupling capacitor design for 90nm and below. To improve the power-grid noise reduction capability in the areas between blocks, two versions of a switched-decap design are proposed. One provides excellent decap performance but consumes large power, whereas the other saves power but suffers from excessive delay. A novel low-power voltage regulator using switched decaps is proposed to better balance performance and power consumption.

description: Command and control (C2) paths for issuing commands to malware are sometimes the only indicators of its existence within networks. Identifying potential C2 channels is often a manually driven process that involves a deep understanding of cyber tradecraft. Efforts to improve discovery of these channels through using a reinforcement learning (RL) based approach that learns to automatically carry out C2 attack campaigns on large networks, where multiple defense layers are in place serves to drive efficiency for network operators. In this paper, we model C2 traffic flow as a three-stage process and formulate it as a Markov decision process (MDP) with the objective to maximize the number of valuable hosts whose data is exfiltrated. The approach also specifically models payload and defense mechanisms such as firewalls which is a novel contribution. The attack paths learned by the RL agent can in turn help the blue team identify high-priority vulnerabilities and develop improved defense strategies. The method is evaluated on a large network with more than a thousand hosts and the results demonstrate that the agent can effectively learn attack paths while avoiding firewalls.

description: Fe$_{5-x}$GeTe$_2$ is a promising two-dimensional (2D) van der Waals (vdW) magnet for practical applications, given its magnetic properties. These include Curie temperatures above room temperature, and topological spin textures (TST or both merons and skyrmions), responsible for a pronounced anomalous Hall effect (AHE) and its topological counterpart (THE), which can be harvested for spintronics. Here, we show that both the AHE and THE can be amplified considerably by just adjusting the thickness of exfoliated Fe$_{5-x}$GeTe$_2$, with THE becoming observable even in zero magnetic field due to a field-induced unbalance in topological charges. Using a complementary suite of techniques, including electronic transport, Lorentz transmission electron microscopy, and micromagnetic simulations, we reveal the emergence of substantial coercive fields upon exfoliation, which are absent in the bulk, implying thickness-dependent magnetic interactions that affect the TST. We detected a ``magic" thickness $t \sim $30 nm where the formation of TST is maximized, inducing large magnitudes for the topological charge density ($6.45 \times 10^{20}$ cm$^{-2}$), and the concomitant anomalous ($ρ_{xy}^{\text{A,max}} \simeq 22.6$ $μΩ$cm) and topological ($ρ_{xy}^{\text{u,T}} \simeq 15$ $μΩ$ cm) Hall resistivities at $T$ ~ 120 K. These values for $ρ_{xy}^{\text{A,max}}$ and $ρ_{xy}^{\text{u,T}}$ are higher than those found in magnetic topological insulators and, so far, the largest reported for 2D magnets. The hitherto unobserved THE under zero magnetic field could provide a platform for the writing and electrical detection of TST aiming at energy-efficient devices based on vdW ferromagnets.

Electron-vibration-vibration two-dimensional infrared spectroscopy: a tool to investigate interactions in plant proteins and mammalian peptides
Creators: name: Sim, Sophie Anne
Publisher: name: Imperial College London
Year: 2018

description: The structural elucidation and characterisation of biomolecular complexes is crucial to both the agrichemical and pharmaceutical industries. Understanding the specific interactions that govern protein-inhibitor interactions enables more intelligent design of herbicide and drug candidates. While there are powerful tools currently available to obtain protein-inhibitor structures, they alone cannot answer the questions posed by protein-inhibitor binding. EVV 2DIR spectroscopy is a novel technique capable of detecting protein-inhibitor interactions that can provide structural information complementary to that of other methods (such as direct measurement of hydrogen bond formation) to build up a more complete picture of protein-inhibitor binding. This thesis presents the first EVV 2DIR spectra of plant protein-inhibitor complexes, comprised of the herbicide target 4-Hydroxyphenylpyruvic acid dioxygenase (HPPD) bound to various herbicide candidates. Difference spectra of HPPD and project compound 329 consistently showed one cross-peak that could be tentatively assigned to coupled vibrational modes specific to protein-inhibitor binding. The data presented exhibits the capability of EVV 2DIR spectroscopy to detect protein-inhibitor binding for plant systems and demonstrates its potential as a tool for the screening of herbicide candidates. The first EVV 2DIR spectra for the peptide amyloid beta (1-40) both with and without Cu(II) and Zn(II) are also presented. Comparison of the spectra reveals changes indicative of the literature observations that amyloid beta (1-40) forms rigid fibrils at an acidic pH, and that the addition of Cu(II) and Zn(II) disrupts and retards fibril formation. Tentative assignments were made for the resultant spectra, however a lack of corresponding calculated EVV 2DIR spectra (previously produced from vibrational modes elucidated via DFT calculations) made definitive assignment of such complex spectra not possible. There are currently no published structures of amyloid beta (1-40) with Cu(II), so accompanying calculated spectra enabling conclusive assignments may reveal significant structural insights into the coordination of copper by amyloid beta in the future.

description: Grants management capacity -- the ability of local governments to identify, attract, and administer Federal grant assistance -- has become an important issue in recent years. As the amount of Federal aid to local governments increased, the limited ability of small local governments to successfully compete for available funds became a vital concern for public officials and policymakers. This inability to compete for Federal funds was further aggravated by the growing number of Federal and State mandates compelling local governments to expand or improve their community facilities and services. These mandates often disregarded the size of the community or its ability to secure and manage intergovernmental aid to finance these improvements.

description: Particle number fluctuations are studied in the microcanonical ensemble. For the Boltzmann statistics we deduce exact analytical formulae for the microcanonical partition functions in the case of non-interacting massless neutral particles and charged particles with zero net charge. The particle number fluctuations are calculated and we find that in the microcanonical ensemble they are suppressed in comparison to the fluctuations in the canonical and grand canonical ensembles. This remains valid in the thermodynamic limit too, so that the well-known equivalence of all statistical ensembles refers to average quantities, but does not apply to fluctuations. In the thermodynamic limit we are able to calculate the particle number fluctuations in the system of massive bosons and fermions when the exact conservation laws of both the energy and charge are taken into account.

description: The problem of resonant tunneling through a quantum dot weakly coupled to spinless Tomonaga-Luttinger liquids has been studied. We compute the linear conductance due to sequential tunneling processes upon employing a master equation approach. Besides the previously used lowest-order golden rule rates describing uncorrelated sequential tunneling (UST) processes, we systematically include higher-order correlated sequential tunneling (CST) diagrams within the standard Weisskopf-Wigner approximation. We provide estimates for the parameter regions where CST effects can be important. Focusing mainly on the temperature dependence of the peak conductance, we discuss the relation of these findings to previous theoretical and experimental results.

Downlink packet scheduling for IEEE 802.16 point-to-multipoint fixed broadband wireless access systems
Creators: name: Zhang, Yonghong
Publisher: name: University of British Columbia
Year: 2010

description: The release of the IEEE 802.16 standard has stimulated commercial interest in deploying fixed broadband wireless access networks. Although the fixed wireless environment is generally less harsh than the mobile environment, the expectations for reliability and performance are also higher. In suburban neighbourhoods, wind-blown foliage is one of the main factors that contribute to fading on fixed wireless channels. It seems likely that fading events associated with the onset of wind will occur simultaneously on multiple links within a given cell. This has important implications for both system performance and radio resource management. In this thesis, we consider the impact of such fading on a single-cell point-to-multipoint system based on the IEEE 802.16 standard. Using an improved Ricean K-factor model that combines elements of previously disclosed models, we show that the performance of the system is degraded when the fading events on multiple links are correlated. Further, we propose two channel-state-dependent downlink schedulers that exploit multi-user diversity for use with TDMA mode IEEE 802.16 point-to-multipoint systems. The first is intended for use with real-time traffic while the second is intended for use with a mixture of real-time, minimum-rate ensured, and best effort traffic. We propose the use of fair degradation for real-time traffic and fair resource allocation for delay-tolerant traffic in order to maintain quality of service (QoS) and mitigate wind-induced fading during heavy wind conditions. Using the new concepts of flexible time and urgent time, our proposed schedulers are able to maximize system throughput while meeting users’ different levels of QoS requirements. Simulation results show that the proposed schedulers outperform existing scheduling schemes, especially during fading events associated with wind blowing through foliage.

description: We derive simple analytic expressions for the continuum lightcurves and spectra of flaring and flickering events that occur over a wide range of astrophysical systems. We compare these results to data taken from the cataclysmic variable SS Cygni and also with SN 1987A, deriving physical parameters for the material involved. Fits to the data indicate a nearly time-independent photospheric temperature arising from the strong temperature dependence of opacity when hydrogen is partially ionized.

Traffic engineering methods for a network processor based multimedia router
Creators: name: Elramly, Amr
Publisher: name: University of British Columbia
Year: 2010

description: The thesis proposes methods to build network processor based multimedia router that provides more services than what is offered by the most expensive network routers. The new methods provide scalability to serve hundreds of thousands of multimedia streams and serve fast enough to meet the low latency required by the multimedia application. The first method proposed is a proxy agent that turns the router into multimedia aware router by preparing the profiling and the routing information for the forwarder and the scheduler, which simplifies the processes required for the rest of the router operation. The second method is Lowest Credit Weighted Fair Queuing or LCWFQ scheduler, that achieves a fairness index of 1 (One) and a work order of O(1) which is similar to the famous Deficit Round Robin (DRR) scheduling algorithm, except that the LCWFQ avoids the DRR weakness in implementation. The third method is an Adaptive Weight Adjustment (AWA) traffic shaper that the Internet Service Provider (ISP) may use when the total ISP commitments to the subscribers are more than what the network can handle. The AWA also serves the bursty streams when conflicting with the assigned SLA while maintains fair services to non-bursty traffic. The forth method is a three level memory index that fast search a record in the forwarding table where the number of memory accesses is always three no matter how large is the forwarding table. The thesis also includes two methods to translate the Service Level Agreement (SLA) into scheduling profiles and to report any bandwidth over-usage to help redefining the subscriber SLA. The proposed methods are designed to fit the network processors abilities to implement loosely coupled profiling, traffic shaping and scheduling.

description: We study a model of strongly correlated fermions in one dimension with extended N=2 supersymmetry. The model is related to the spin $S=1/2$ XXZ Heisenberg chain at anisotropy $Δ=-1/2$ with a real magnetic field on the boundary. We exploit the combinatorial properties of the ground state to determine its exact wave function on finite lattices with up to 30 sites. We compute several correlation functions of the fermionic and spin fields. We discuss the continuum limit by constructing lattice observables with well defined finite size scaling behavior. For the fermionic model with periodic boundary conditions we give the emptiness formation probability in closed form.

description: We study the world volume theory of D3-branes wrapping the Melvin universe supported by background NSNS B-field. In the appropriate decoupling limit, the open string dynamics is that of non-commutative guage field theory with non-constant non-commutativity. We identify this model as a simple Melvin twist of flat D3 branes. Along similar lines, one recognizes the model of Hashimoto and Sethi as being the Melvin null twist, and the model of Dolan and Nappi as being the null Melvin twist, of the flat D3-brane. This construction therefore offers a unified perspective on most of the known explicit constructions of non-commutative gauge theories as a decoupled theory of D-branes in a B-field background. We also describe the world volume theory on the D3-brane in Melvin universe which is decaying via the nucleation of monopole anti-monopole pair.

description: Signal processing has become central to many fields, from coherent optical telecommunications, where it is used to compensate signal impairments, to video image processing. Image processing is particularly important for observational astronomy, medical diagnosis, autonomous driving, big data and artificial intelligence. For these applications, signal processing traditionally has mainly been performed electronically. However these, as well as new applications, particularly those involving real time video image processing, are creating unprecedented demand for ultrahigh performance, including high bandwidth and reduced energy consumption. Here, we demonstrate a photonic signal processor operating at 17 Terabits/s and use it to process video image signals in real-time. The system processes 400,000 video signals concurrently, performing 34 functions simultaneously that are key to object edge detection, edge enhancement and motion blur. As compared with spatial-light devices used for image processing, our system is not only ultra-high speed but highly reconfigurable and programable, able to perform many different functions without any change to the physical hardware. Our approach is based on an integrated Kerr soliton crystal microcomb, and opens up new avenues for ultrafast robotic vision and machine learning.

description: Optical parametric amplification (OPA) represents a powerful solution to achieve broadband amplification in wavelength ranges beyond the scope of conventional gain media, for generating high-power optical pulses, optical microcombs, entangled photon pairs and a wide range of other applications. Here, we demonstrate optical parametric amplifiers based on silicon nitride (Si3N4) waveguides integrated with two-dimensional (2D) layered graphene oxide (GO) films. We achieve precise control over the thickness, length, and position of the GO films using a transfer-free, layer-by-layer coating method combined with accurate window opening in the chip cladding using photolithography. Detailed OPA measurements with a pulsed pump for the fabricated devices with different GO film thicknesses and lengths show a maximum parametric gain of ~24.0 dB, representing a ~12.2 dB improvement relative to the device without GO. We perform a theoretical analysis of the device performance, achieving good agreement with experiment and showing that there is substantial room for further improvement. This work represents the first demonstration of integrating 2D materials on chips to enhance the OPA performance, providing a new way of achieving high performance photonic integrated OPA by incorporating 2D materials.

description: We study the shearing of polydisperse and bidisperse media with a size ratio of 10. Simulations are performed with a the two dimensional shear cell using contact dynamics. With a truncated power law for the polydisperse media we find that they show a stronger dilatancy and greater resistance to shearing than bidisperse mixtures. Motivated by the practical problem of reducing the energy needed to shear granular media, we introduce "point-like particles" representing charged particles in the distribution. Even though changing the kinematic behavior very little, they reduce the force necessary to maintain a fixed shearing velocity.

description: We extend the analogy between charge-based bipolar semiconductor electronics and spin-based unipolar electronics by considering unipolar spin transistors with different equilibrium spin splittings in the emitter, base, and collector. The current of base majority spin electrons to the collector limits the performance of ``homojunction'' unipolar spin transistors, in which the emitter, base, and collector all are made from the same magnetic material. This current is very similar in origin to the current of base majority carriers to the emitter in homojunction bipolar junction transistors. The current in bipolar junction transistors can be reduced or nearly eliminated through the use of a wide band gap emitter. We find that the choice of a collector material with a larger equilibrium spin splitting than the base will similarly improve the device performance of a unipolar spin transistor. We also find that a graded variation in the base spin splitting introduces an effective drift field that accelerates minority carriers through the base towards the collector.
