description: In this paper we analyze the classical electromagnetic radiation of an accelerating point charge moving on a straight line trajectory. Depending on the duration of accelerations, rapidity distributions of photons emerge, resembling the ones obtained in the framework of hydrodynamical models by Landau or Bjorken. Detectable differences between our approach and spectra obtained from hydrodynamical models occur at high transverse momenta and are due to interference.

description: The influence of acceleration and rotation on spintronic applications is theoretically investigated. In our formulation, considering a Dirac particle in a non-inertial frame, different spin related aspects are studied. The spin current appearing due to the inertial spin-orbit coupling (SOC) is enhanced by the interband mixing of the conduction and valence band states. Importantly, one can achieve a large spin current through the $\vec{k}. \vec{p}$ method in this non-inertial frame. Furthermore, apart from the inertial SOC term due to acceleration, for a particular choice of the rotation frequency, a new kind of SOC term can be obtained from the spin rotation coupling (SRC). This new kind of SOC is of Dresselhaus type and controllable through the rotation frequency. In the field of spintronic applications, utilizing the inertial SOC and SRC induced SOC term, theoretical proposals for the inertial spin filter, inertial spin galvanic effect are demonstrated. Finally, one can tune the spin relaxation time in semiconductors by tuning the non-inertial parameters.

Non c'è credenza, per riprendere genericamente Peirce, che non abbia delle conseguenze pratiche. Questo può gettare una luce su distinti campi della ricerca filosofica, come le teorie del significato, della conoscenza, dei valori. In un'ottica pragmatista si può configurare una teoria del significato in termini di conseguenze pratiche, una teoria della conscenza che ne rilevi gli aspetti pratici, una toeria dei valori che ne metta in luce gli aspetti cognitivi.

description: Human-Computer Interaction with the traditional User Interface is done using a specified in advance script dialog menu, mainly based on human intellect and unproductive use of navigation. This approach does not lead to making qualitative decision in control systems, where the situations and processes cannot be structured in advance. Any dynamic changes in the controlled business process (as example, in organizational unit of the information fuzzy control system) make it necessary to modify the script dialogue in User Interface. This circumstance leads to a redesign of the components of the User Interface and of the entire control system. In the Intelligent User Interface, where the dialog situations are unknown in advance, fuzzy structured and artificial intelligence is crucial, the redesign described above is impossible. To solve this and other problems, we propose the data, information and knowledge based technology of Smart/ Intelligent User Interface (IUI) design, which interacts with users and systems in natural and other languages, utilizing the principles of Situational Control and Fuzzy Logic theories, Artificial Intelligence, Linguistics, Knowledge Base technologies and others. The proposed technology of IUI design is defined by multi-agents of Situational Control and of data, information and knowledge, modelling of Fuzzy Logic Inference, Generalization, Representation and Explanation of knowledge, Planning and Decision-making, Dialog Control, Reasoning and Systems Thinking, Fuzzy Control of organizational unit in real-time, fuzzy conditions, heterogeneous domains, and multi-lingual communication under uncertainty and in Fuzzy Environment.

title: Signal Processing for Radar-Based Gait Analysis
Creators: name: Seifert, Ann-Kathrin
Publisher: name: UNSPECIFIED
Year: 2020

description: In this PhD thesis signal processing methods are developed for radar-based gait analysis. Analyzing the backscattered radio frequency waves from a moving non-rigid target in the time-frequency domain, reveals so-called micro-Doppler signatures. In the case of a walking person, these micro-Doppler signatures relate to gait kinematics by capturing velocity, acceleration, and rotation of individual body parts. Hence, they can be exploited for general gait classification and basic gait analysis. In the area of radar-based gait classification, a signal processing framework is developed to discriminate between five walking styles, including abnormal and cane-assisted gait. Toward this end, different joint-variable signal representations, including the spectrogram and the so-called cadence-velocity diagram, are adapted. These representations are used to identify physically interpretable features, and as input to automatic feature learning using principal component analysis. The thus obtained feature sets are evaluated and compared in terms of their corresponding classification performance. Additionally, a gait asymmetry detector is presented to identify differences between the left and right leg's motions from radar micro-Doppler signatures. The evaluation of the developed methods is based on realistic experimental radar data of 10 able-bodied individuals, and four persons with diagnosed gait disorders. Toward radar-based gait analysis, the thesis demonstrates the use of Doppler radar for measuring a set of medically relevant gait parameters, including stride time and maximal lower limb velocities. Here, a new method is presented for measuring the flight time through a radar device. In total, 11 biomechanical gait parameters are extracted and qualitatively and quantitatively assessed by using marker-based motion capture data. Further, parametric models for the radial velocities of the lower limbs during walking are developed. These models are then employed to estimate lower limb angular kinematics, namely, the hip and knee angle, from radar micro-Doppler step signatures. The developed methods are evaluated based on experimental data of 19 able-bodied test persons walking on a treadmill. Here, one of the knees was systematically restricted through an adjustable orthosis to simulate different degrees of gait abnormality. The results of this thesis demonstrate the capabilities of radar to capture differences in gait patterns. In particular, the developed signal processing frameworks allow for discriminating between different walking styles and the measurement of medically relevant gait parameters based on radar backscatterings. Thus, it is shown that radio frequency sensing is a viable technology for unobtrusive in-home gait analysis. As such, this thesis contributes to the growing field of radar for indoor human monitoring with application to, e.g., telemedicine and assisted living.
Dynamics of the two-dimensional directed Ising model in the paramagnetic phase

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We consider the non-conserved dynamics of the Ising model on the two-dimensional square lattice, where each spin is influenced preferentially by its East and North neighbours. The single-spin flip rates are such that the stationary state is Gibbsian with respect to the usual ferromagnetic Ising Hamiltonian. We show the existence, in the paramagnetic phase, of a dynamical transition between two regimes of violation of the fluctuation-dissipation theorem in the nonequilibrium stationary state: a regime of weak violation where the stationary fluctuation-dissipation ratio is finite, when the asymmetry parameter is less than a threshold value, and a regime of strong violation where this ratio vanishes asymptotically above the threshold. The present study suggests that this novel kind of dynamical transition in nonequilibrium stationary states, already found for the directed Ising chain and the spherical model with asymmetric dynamics, might be quite general. In contrast with the later models, the equal-time correlation function for the two-dimensional directed Ising model depends on the asymmetry.

description: A search is presented for new particles in an extension to the Standard Model that includes a heavy Higgs boson H0, an intermediate charged Higgs boson pair H+-, and a light Higgs boson h0. The analysis searches for events involving the production of a single heavy neutral Higgs boson which decays to the charged Higgs boson and a W boson, where the charged Higgs boson subsequently decays into a W boson and the lightest neutral Higgs boson decaying to a bottom--antibottom-quark pair. Such a cascade results in a W-boson pair and a bottom--antibottom-quark pair in the final state. Events with exactly one lepton, missing transverse momentum, and at least four jets are selected from a data sample corresponding to an integrated luminosity of 20.3/fb, collected by the ATLAS detector in proton--proton collisions at sort(s)=8 TeV at the LHC. The data are found to be consistent with Standard Model predictions, and 95% confidence-level upper limits are set on the product of cross section and branching ratio. These limits range from 0.065 pb to 43 pb as a function of H0 and H+- masses, with m(h0) fixed at 125 GeV.

Analysis of multi-frequency subspace migration weighted by natural logarithmic function for fast imaging of two-dimensional thin, arc-like electromagnetic inhomogeneities

description: The present study seeks to investigate mathematical structures of a multi-frequency subspace migration weighted by the natural logarithmic function for imaging of thin electromagnetic inhomogeneities from measured far-field pattern. To this end, we designed the algorithm and calculated the indefinite integration of square of Bessel function of order zero of the first kind multiplied by the natural logarithmic function. This is needed for mathematical analysis of improved algorithm to demonstrate the reason why proposed multi-frequency subspace migration contributes to yielding better imaging performance, compared to previously suggested subspace migration algorithm. This analysis is based on the fact that the singular vectors of the collected Multi-Static Response (MSR) matrix whose elements are the measured far-field pattern can be represented as an asymptotic expansion formula in the presence of such inhomogeneities. To support the main research results, several numerical experiments with noisy data are illustrated.

On Piterbarg Max-discretisation Theorem for Multivariate Stationary Gaussian Processes

description: Let $\{X(t), t\geq0\}$ be a stationary Gaussian process with zero-mean and unit variance. A deep result derived in Piterbarg (2004), which we refer to as Piterbarg's max-discretisation theorem gives the joint asymptotic behaviour ($T\to \infty$) of the continuous time maximum $M(T)=\max_{t\in [0,T]} X(t), $ and the maximum $M^δ(T)=\max_{t\in \mathfrak{R}(δ)}X(t), $ with $\mathfrak{R}(δ) \subset [0,T]$ a uniform grid of points of distance $δ=δ(T)$. Under some asymptotic restrictions on the correlation function Piterbarg's max-discretisation theorem shows that for the limit result it is important to know the speed $δ(T)$ approaches 0 as $T\to \infty$. The present contribution derives the aforementioned theorem for multivariate stationary Gaussian processes.

description: A novel Air-breathing Microwave Plasma CAThode (AMPCAT) is developed to support air-breathing electric propulsion in very-low altitude orbits. In this paper, the AMPCAT plasma properties are investigated in standalone testing and compared to a hollow cathode for operation on xenon. The AMPCAT is validated through coupling with a low-power cylindrical Hall thruster (CHT), analysing both the thruster performance and plasma properties. CHT operation on xenon is sustained with the AMPCAT running on air, allowing an investigation of the influence of air as the cathode propellant and the beneficial impact of AMPCAT coupling on thruster performance recorded at low discharge voltages.

description: A number of metrics for quantifying the amount of functional redundancy in a community have been proposed over the years. Two of the most popular metrics are based on comparing a taxonomic diversity measure with a generalized form of the same measure that accounts for functional dissimilarities between taxa. These two metrics express redundancy as either an absolute or relative difference between the taxonomic diversity measure and its generalized form. Because they express the amount of redundancy in a community in terms of raw diversity values, both redundancy metrics are susceptible to the same issues that complicate the interpretation of most commonly used diversity indices. It is possible to overcome these issues by restating these two indices using a Hill numbers framework. As a growing number of authors have noted, these modified metrics provide a more intuitive quantitative definition of functional redundancy when used to rank communities. Beyond this intuitive definition, measuring redundancy in terms of Hill numbers allows researchers to control the influence of rare taxa on the output value, enabling ecologists to better predict how a community is expected to respond when exposed to an external perturbation that selectively eliminates rare or common taxa. Here I show that, of the two possible Hill number-based redundancy metrics, the form based on a popular absolute redundancy metric is extremely sensitive to differences in taxonomic diversity and can provide a misleading picture of how much redundancy is present in a community. For this reason, I argue that Hill number-based functional redundancy should be quantified using a relative metric that explicitly accounts for differences in effective taxonomic diversity. The proposed Hill number-based relative redundancy measure is shown to provide a much more complete picture of the distribution of redundant taxa within a community, highlighting subtle patterns that are completely missed by the Hill number-based absolute redundancy metric.

description: We {\it analytically} compute, to the eight-and-a-half post-Newtonian order, and to linear order in the mass ratio, the radial potential describing (within the effective one-body formalism) the gravitational interaction of two bodies, thereby extending previous analytic results. These results are obtained by applying analytical gravitational self-force theory (for a particle in circular orbit around a Schwarzschild black hole) to Detweiler's gauge-invariant redshift variable. We emphasize the increase in \lq\lq transcendentality" of the numbers entering the post-Newtonian expansion coefficients as the order increases, in particular we note the appearance of $ζ(3)$ (as well as the square of Euler's constant $γ$) starting at the seventh post-Newtonian order. We study the convergence of the post-Newtonian expansion as the expansion parameter $u=GM/(c^2r)$ leaves the weak-field domain $u\ll 1$ to enter the strong field domain $u=O(1)$.

description: New Gemini mid-infrared spectroscopic observations together with Spitzer Space telescope archival data, are used to study the properties of the dusty torus and circumnuclear star formation in the active galaxies NGC 7213 and NGC 1386. Our main conclusions can be summarised as follows. Polycyclic aromatic hydrocarbon (PAH) emission is absent in the T-ReCS nuclear spectra but is ubiquitous in the data from Spitzer at distances above 100 pc. Star formation rates surface densities are estimated from the 12.8 $μm$ [Ne{\sc ii}] line strengths leading to values close to 0.1M$_\odot\,\,{\rm yr}^{-1}\,\,{\rm kpc}^{-2}$. Analogous estimates based on photometric fluxes of IRAC's 8 $μm$ images are higher by a factor of almost 15, which could be linked to excitation of PAH molecules by older stellar populations. T-ReCS high spatial resolution data reveal silicate absorption at $λ$ 9.7 $μm$ in the central tens of parsecs of the Seyfert 2 NGC 1386, and silicate emission in the Seyfert 1 galaxy NGC 7213. In the case of NGC 1386 this feature is confined to the inner 20 pc, implying that the silicate might be linked to the putative dusty torus. Finally, by fitting CLUMPY models to the T-ReCS nuclear spectra we estimate the torus physical properties for both galaxies, finding line of sight inclinations consistent with the AGN unified model.

description: The transmission eigenvalues corresponding to the half-line Schrödinger equation with the general selfadjoint boundary condition is analyzed when the potential is real valued, integrable, and compactly supported. It is shown that a transmission eigenvalue corresponds to the energy at which the scattering from the perturbed system agrees with the scattering from the unperturbed system. A corresponding inverse problem for the recovery of the potential from a set containing the boundary condition and the transmission eigenvalues is analyzed, and a unique reconstruction of the potential is given provided one additional constant is contained in the data set. The results are illustrated with various explicit examples.

MESH ADAPTATION
ELECTRIC ARC

description: can be broken down into two phases. In the pulsed phase, the current intensity can go to 200kA in a few microseconds with compressible flow characteristics, and in the continuous phase, the current is constant with intensities of a few I 00A and for durations of hundreds of milliseconds with incompressible flow characteristics. The numerical modelling of this phenomenon is very complex as it involves different physics (fluid dynamics, electromagnetism, radiation ... ), and the computational time consumption in the case of 3D simulation is extremely high because the refinement required results in a mesh containing up to several hundred million cells. An ideal solution to reduce this calculation cost would be to mesh only where necessary and, therefore, to have a mesh that will adapt in space and time according to the physics encountered. The magnetohydrodynamic (MHD) 2D/3D code Taranis developed at ONERA is coupled with feflo.a [22], an anisotropic mesh adaptation code developed at INRIA. These tools make it possible to greatly reduce the number of nodes in the mesh and, therefore, greatly reduce modelling times. However, as Taranis is a code using explicit compressible methods, the simulation of continuous arcs, even with these mesh adaptation tools, remains very costly due to the incompressible nature of the flow, where very small-time steps must be used to maintain stability. A proposed solution for simulating continuous arcs with a compressible method is to use semi-implicit schemes. The nature of these schemes makes it possible to increase the value of the time steps to values close to those used in incompressible methods while maintaining stability. In this paper, the method of Boscheri et al. [8][9] dealing with the Navier-Stokes equations in real gas is used. Modifications are made to the treatment of real gas, where thermodynamic tables are used instead of equations of state. The scheme is then tested in compressible flow configurations and then in a flow representing, in a simplified way, the flow of a continuous arc. Initial results have shown the scheme\'s ability to simulate compressible and incompressible flows for larger time steps and with greater accuracy than a conventional compressible scheme.

description: Due to the increasingly need for automatic traffic monitoring, vehicle license plate detection is of high interest to perform automatic toll collection, traffic law enforcement, parking lot access control, among others. In this paper, a sliding window approach based on Histogram of Oriented Gradients (HOG) features is used for Brazilian license plate detection. This approach consists in scanning the whole image in a multiscale fashion such that the license plate is located precisely. The main contribution of this work consists in a deep study of the best setup for HOG descriptors on the detection of Brazilian license plates, in which HOG have never been applied before. We also demonstrate the reliability of this method ensured by a recall higher than 98% (with a precision higher than 78%) in a publicly available data set.

description: Thanks to a new derivation of the fundamental equations governing multimode dynamics for a semiconductor laser near its threshold, we identify regimes of existence of a pure phase instability (and of a mixed phase-amplitude turbulence regime) which give an alternative satisfactory interpre- tation of the deterministic multimode dynamics observed in some devices. The existence of intrinsic noise generated by the phase instability reconciles in the same description the deterministic and random features of the semiconductor dynamics.

LOW RNP VALUES

description: Data analytical results gathered in flight trials in the course of introducing Performance Based Navigation (PBN) are shown. Switzerland has extensively researched and probed into Instrument Flight Rules (IFR) helicopter operations. This resulted in performance bounds beyond OEM-certified limits. Light helicopters have limited capability to carry extensive avionics because to other mission critical on-board equipment. Operational scenarios however include all-weather capability. The flight trials with board mounted flight calibration equipment for helicopters had, among other objectives the gathering of the lateral (cross track) Navigation System Error (NSE) and Total System Error (TSE) of an auto-piloted light helicopter. The helicopter navigates with only GPS/SBAS Ll CIA NA V. The OEM certified it for RNP0.3. Besides navigation errors and its correlation indications of instrument flight procedure design for low RNP values is illustrated.

description: Galaxy clusters can efficiently convert axion-like particles (ALPs) to photons. We propose that the recently claimed detection of a 3.55--3.57 keV line in the stacked spectra of a large number of galaxy clusters and the Andromeda galaxy may originate from the decay of either a scalar or fermionic $7.1$ keV dark matter species into an axion-like particle (ALP) of mass $m_{a} \lesssim 6\cdot 10^{-11}~{\rm eV}$, which subsequently converts to a photon in the cluster magnetic field. In contrast to models in which the photon line arises directly from dark matter decay or annihilation, this can explain the anomalous line strength in the Perseus cluster. As axion-photon conversion scales as $B^2$ and cool core clusters have high central magnetic fields, this model can also explains the observed peaking of the line emission in the cool cores of the Perseus, Ophiuchus and Centaurus clusters, as opposed to the much larger dark matter halos. We describe distinctive predictions of this scenario for future observations.

description: Jake MacMillan, although by training and personal acclamation ‘first and foremost an organic chemist’, was one of the UK's most brilliant interdisciplinary scientists. A pioneer in the field of bioorganic chemistry, he was practising what we would now call synthetic biology 40 years before the term was coined. A young PhD student or post-doctoral research associate joining his group would mix with chemists, plant physiologists, fungal geneticists and enzymologists as well as being exposed to internationally leading natural product chemistry, advanced organic synthesis, mechanistic studies and state-of-the-art analytical methods, including emerging techniques such as gas chromatography–mass spectrometry. His multidisciplinary approach to tackling major problems at the chemistry–biology interface was undoubtedly influenced by his early research career working in the famed Butterfield (later Akers) Laboratory set up by ICI as a basic research establishment in the grounds of a Victorian house, The Frythe. There, he isolated and elucidated the structure of the important antifungal agent griseofulvin, before initiating his life-long interest in the gibberellins. These diterpenoid natural products were originally isolated as phytotoxic fungal metabolites, before their role as essential plant-growth regulators present in all higher plants was established. He moved to Bristol in 1963 to commence an academic career as a lecturer at the relatively advanced age of 39. He became the world authority on the chemistry, biosynthesis and biology of the gibberellins, rising through the academic ranks to be awarded a personal chair in 1978.
Edge and Interfacial States in a 2D Topological Insulator:Bi(111) Bilayer on Bi$_{2}$Te$_{2}$Se

description: The electronic states of a single Bi(111) bilayer and its edges, suggested as a two dimensional topological insulator, are investigated by scanning tunneling spectroscopy (STS) and first-principles calculations. Well-ordered bilayer films and islands with zigzag edges are grown epitaxially on a cleaved Bi$_{2}$Te$_{2}$Se crystal. The calculation shows that the band gap of the Bi bilayer closes with a formation of a new but small hybridization gap due to the strong interaction between Bi and Bi$_{2}$Te$_{2}$Se. Nevertheless, the topological nature of the Bi bilayer and the topological edge state are preserved only with an energy shift. The edge-enhanced local density of states are identified and visualized clearly by STS in good agreement with the calculation. This can be the sign of the topological edge state, which corresponds to the quantum spin Hall state. The interfacial state between Bi and Bi$_{2}$Te$_{2}$Se is also identified inside the band gap region. This state also exhibits the edge modulation, which was previously interpreted as the evidence of the topological edge state [F. Yang et al., Phys. Rev. Lett. 109, 016801 (2012)].

Investigating the power and energy flows for a Kinetic Energy Recovery from a landing aircraft

POWER FLOW SIMULATION

description: This paper investigates the power and energy flows for a kinetic energy recovery system from a landing aircraft. The concept studied here uses electrical motors installed at the wheels to produce regenerative braking during rollout. This energy is stored temporarily into a flywheel energy storage device and is then transferred back to the wheels for engineless taxiing. The paper develops an aircraft dynamics model to assess the bi-directional power and energy transfer. The model is tested with two case studies; the A320 and the ATR-72 aircraft, thus assessing a wide spectrum for short haul flights. Simulated results show that during normal operation, there is sufficient energy that can be harvested from a landing aircraft that may be used for taxiing purposes. However, the short rollout time places a stringent demand on the system which is limited by the safety aspect of performance limited runways or busy major airports requiring minimum runway occupancy time operation. This limitation can be overcome by increasing the motor torque rating.
Thermal effects on the sudden changes and freezing of correlations between remote atoms in cavity QED network

description: We investigate the thermal effects on the sudden changes and freezing of the quantum and classical correlations of remote qubits in a cavity quantum electrodynamics (CQED) network with losses. We find that the detrimental effect of the thermal reservoirs on the system can be compensated via an efficient coupling of the fiber connecting the two cavities of the system. Furthermore, for certain initial conditions, we find a double sudden transitions in the dynamics of Bures geometrical quantum discord. The second transition tends to disappear at a critical temperature, hence freezing the discord. Finally, we discuss some ideas of the experimental realization of the present proposal.

description: We calculate numerically the fidelity and its susceptibility for the ground state of the Dicke model. A minimum in the fidelity identifies the critical value of the interaction where a quantum phase crossover, the precursor of a phase transition for finite number of atoms N, takes place. The evolution of these observables is studied as a function of N, and their critical exponents evaluated. Using the critical exponents the universal curve for the specific susceptibility is recovered. An estimate to the precision to which the ground state wave function is numerically calculated is given, and found to have its lowest value, for a fixed truncation, in a vicinity of the critical coupling.

description: This article is concerned with matching feature vectors in a one-to-one fashion across large collections of datasets. Formulating this task as a multidimensional assignment problem with decomposable costs (MDADC), we develop fast algorithms with time complexity roughly linear in the number n of datasets and space complexity a small fraction of the data size. These remarkable properties hinge on using the squared Euclidean distance as dissimilarity function, which can reduce (n2) matching problems between pairs of datasets to n problems and enable calculating assignment costs on the fly. To our knowledge, no other method applicable to the MDADC possesses these linear scaling and low-storage properties necessary to large-scale applications. In numerical experiments, the novel algorithms outperform competing methods and show excellent computational and optimization performances. An application of feature matching to a large neuroimaging database is presented. The algorithms of this article are implemented in the R package matchFeat available at github.com/ddegras/matchFeat. Supplementary materials for this article are available online.
