Anodised Aluminium Foil Winding Axial Flux Machine for High Torque Density Robot Actuators
Creators: name: Van Damme, Jordi
name: Vansompel, Hendrik
name: Crevecoeur, Guillaume
Publisher: name: Zenodo
Year: 2022

description: There is a need for higher torque density electric actuators in novel (quasi-)direct-drive robotic applications. Since the torque density is inherently limited by material properties, designers have to look at novel materials to push the torque density limit further. In this work, anodised aluminium foil is considered as an alternative to enamelled copper wire in a yokeless and segmented armature axial flux machine. This machine topology has a high torque density and is particularly suited for an anodised aluminium foil winding. The DC resistance, thermal properties and eventually the torque density of a prototype
 test case machine are compared for both winding materials. A 3D thermal finite element model is used to analyse the influence of the thermal interface between winding body and housing, and the influence of the cooling performance on the torque density. This has shown that the use of anodised aluminium foil can increase the torque density up to 37%. To conclude, anodised aluminium foil winding offers a higher torque density in direct-drive yokeless and segmented armature axial flux actuators where the winding body thermal resistance is dominant in the thermal path from heat source to heat sink. It is experimentally shown that for the prototype machine, the torque per kg active stator mass increases 13% through the use of anodised aluminium foil.

description: The current status of various thermal and statistical descriptions of particle production in the ultra-relativistic heavy-ion collisions experiments is presented in detail. We discuss the formulation of various types of thermal models of a hot and dense hadron gas (HG) and the methods incorporated in implementing the interactions between hadrons. We first obtain the parameterization of center-of-mass energy ($\sqrt{s_{NN}}$) in terms of temperature ($T$) and baryon chemical potential ($μ_B$) obtained by analyzing the particle ratios at the freeze-out over a broad energy range from the lowest Alternating Gradient Synchrotron (AGS) energy to the highest Relativistic Heavy-Ion Collider (RHIC) energies. The results of various thermal models together with the experimental results for the various ratios of yields of produced hadrons are then compared. We have derived some new universal conditions emerging at the chemical freeze-out of HG fireball which demonstrate the independence with respect to the energy as well as the structure of the nuclei used in the collision. Further, we perform the calculation of various transport properties of HG such as shear viscosity-to-entropy density ratio ($η/s$) etc. using thermal model and compare with the results of other models. We also present the calculation of the rapidity as well as transverse mass spectra of various hadrons in the thermal HG model. The purpose of this review article is to organize and summarize the experimental data obtained in various experiments with heavy-ion collisions and then to examine and analyze them using thermal models so that a firm conclusion regarding the formation of quark-gluon plasma (QGP) can be obtained.

description: We estimate the maximum temperature at which planets can form via gravitational instability (GI) in the outskirts of early circumstellar disks. We show that due to the temperature floor set by the cosmic microwave background, there is a maximum distance from their host stars beyond which gas giants cannot form via GI, which decreases with their present-day age. Furthermore, we show that planet formation via GI is not possible at metallicities < 10^-4 Z_Sun, due to the reduced cooling efficiency of low-metallicity gas. This critical metallicity for planet formation via GI implies a minimum distance from their host stars of ~ 6 AU within which planets cannot form via GI; at higher metallicity, this minimum distance can be significantly greater, out to several tens of AU. We show that these maximum and minimum distances significantly constrain the number of observed planets to date that are likely to have formed via GI at their present locations. That said, the critical metallicity we find for GI is well below that for core accretion to operate; thus, the first planets may have formed via GI, although only within a narrow region of their host circumstellar disks.

description: The spirit and philosophy of Open Access are in sync with FAIFE owing to its visible role in sharing intellectual freedom for building information democracy. But with the exponential increase of cost of scholarly research publication and capture of a huge portion of publication industry by for-profit publishers create a void between the research and researcher, information and seeker, educator and learner, query and the solutions. This paper illustrates the hidden cause of this crisis in scholarly communication and gives a brief understanding of total open access movement, from past initiative to future plans. Additionally, this paper thoroughly pointed out the tools and platforms which can be used by educators and researchers to promote this open access movement with great success. The paper reflects the value of open access movement in the way to eliminate the communication gap in terms of scholarly research work.

description: We address the distributed estimation of an unknown scalar parameter in Wireless Sensor Networks (WSNs). Sensor nodes transmit their noisy observations over multiple access channel to a Fusion Center (FC) that reconstructs the source parameter. The received signal is corrupted by noise and channel fading, so that the FC objective is to minimize the Mean-Square Error (MSE) of the estimate. In this paper, we assume sensor node observations to be correlated with the source signal and correlated with each other as well. The correlation coefficient between two observations is exponentially decaying with the distance separation. The effect of the distance-based correlation on the estimation quality is demonstrated and compared with the case of unity correlated observations. Moreover, a closed-form expression for the outage probability is derived and its dependency on the correlation coefficients is investigated. Numerical simulations are provided to verify our analytic results.

description: We review our current understanding of the internal dynamical properties of the dwarf spheroidal galaxies surrounding the Milky Way. These are the most dark matter dominated galaxies, and as such may be considered ideal laboratories to test the current concordance cosmological model, and in particular provide constraints on the nature of the dominant form of dark matter. We discuss the latest observations of the kinematics of stars in these systems, and how these may be used to derive their mass distribution. We tour through the various dynamical techniques used, with emphasis on the complementarity and limitations, and discuss what the results imply also in the context of cosmological models. Finally we provide an outlook on exciting developments in this field.

description: Consider anomalous energy spread in solid phases, i.e., $MSD= \int (x -{< x >}_E)^2 ρ_E(x,t)dx \propto t^β$, as induced by a small initial excess energy perturbation distribution $ρ_{E}(x,t=0)$ away from equilibrium. The associated total thermal equilibrium heat flux autocorrelation function $C_{JJ}(t)$ is shown to obey rigorously the intriguing relation, $d^2 MSD/dt^2 = 2C_{JJ}(t)/(k_BT^2c)$, where $c$ is the specific volumetric heat capacity. Its integral assumes a time-local Helfand-moment relation; i.e. $ dMSD/dt|_{t=t_s} = 2/(k_BT^2c)\int_0^{t_s} C_{JJ}(s)ds$, where the chosen cut-off time $t_s$ is determined by the maximal signal velocity for heat transfer. Given the premise that the averaged nonequilibrium heat flux is governed by an anomalous heat conductivity, energy diffusion scaling necessarily determines a corresponding anomalous thermal conductivity scaling behavior.

The height of the observed Jc peak decreases with increasing magnetic field in clear contrast with that of the peak effect found at the upper critical field. We also performed the first angular transport measurements of Jc ever conducted on this compound. They reveal the correlated nature of this pinning enhancement, which we attribute to the formation of antiphase boundaries at TN.

description: From both the research community and industry there is an ever-growing interest in the application of UAVs (more commonly known as drones) for use in e.g. agriculture or infrastructure inspection. If a commercial UAV solution comes equipped with a sensor for mapping, it is typically a single RGB camera or a LiDAR system. However, different types of sensors provide different, often complimentary, kinds of information. For example, LiDAR sensors yield geometric information about a scene, whereas an RGB or hyperspectral camera provides colour information. Although much research has been conducted to extract geometric information (3D models) from (2D) images via photogrammetry, this process is extremely complicated and slow and could be sped up immensely by incorporating LiDAR information directly.
 Therefore, ideally we should equip a UAV with all kinds of different sensors. For this reason the UAV Research Centre URC has constructed a sensor rig and is developing a pipeline for the joint processing of the different data modalities, in particular LiDAR and spectral information. In this poster we provide a high-level overview on some design aspects such as the optimal orientation to mount a LiDAR, and the extrinsic calibration.
Circular law for random matrices with unconditional log-concave distribution

description: We explore the validity of the circular law for random matrices with non i.i.d. entries. Let A be a random n \times n real matrix having as a random vector in R^{n^2} a log-concave isotropic unconditional law. In particular, the entries are uncorellated and have a symmetric law of zero mean and unit variance. This allows for some dependence and non equidistribution among the entries, while keeping the special case of i.i.d. standard Gaussian entries. Our main result states that as n goes to infinity, the empirical spectral distribution of n^{-1/2}A tends to the uniform law on the unit disc of the complex plane.
Peaks and dips in Gaussian random fields: a new algorithm for the shear eigenvalues, and the excursion set theory
Creators: name: Rossi, Graziano
Publisher: name: arXiv
Year: 2013
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: We present a new algorithm to sample the constrained eigenvalues of the initial shear field associated with Gaussian statistics, called the `peak/dip excursion-set-based' algorithm, at positions which correspond to peaks or dips of the correlated density field. The computational procedure is based on a new formula which extends Doroshkevich's unconditional distribution for the eigenvalues of the linear tidal field, to account for the fact that halos and voids may correspond to maxima or minima of the density field. The ability to differentiate between random positions and special points in space around which halos or voids may form (peaks/dips), encoded in the new formula and reflected in the algorithm, naturally leads to a straightforward implementation of an excursion set model for peaks and dips in Gaussian random fields - one of the key advantages of this sampling procedure. In addition, it offers novel insights into the statistical description of the cosmic web. As a first physical application, we show how the standard distributions of shear ellipticity and prolateness in triaxial models of structure formation are modified by the constraint. In particular, we provide a new expression for the conditional distribution of shape parameters given the density peak constraint, which generalizes some previous literature work. The formula has important implications for the modeling of non-spherical dark matter halo shapes, in relation to their initial shape distribution. We also test and confirm our theoretical predictions for the individual distributions of eigenvalues subjected to the extremum constraint, along with other directly related conditional probabilities. Finally, we indicate how the proposed sampling procedure naturally integrates into the standard excursion set model, potentially solving some of its well-known problems, and into the ellipsoidal collapse framework.

description: A multidimensional optimization problem is formulated in the tropical mathematics setting as to maximize a nonlinear objective function, which is defined through a multiplicative conjugate transposition operator on vectors in a finite-dimensional semimodule over a general idempotent semifield. The study is motivated by problems drawn from project scheduling, where the deviation between initiation or completion times of activities in a project is to be maximized subject to various precedence constraints among the activities. To solve the unconstrained problem, we first establish an upper bound for the objective function, and then solve a system of vector equations to find all vectors that yield the bound. As a corollary, an extension of the solution to handle constrained problems is discussed. The results obtained are applied to give complete direct solutions to the motivating problems from project scheduling. Numerical examples of the development of optimal schedules are also presented.

description: If there is a dS/CFT correspondence, time evolution in the bulk should translate to RG flows in the dual euclidean field theory. Consequently, although the dual field is expected to be non-unitary, its RG flows will carry an imprint of the unitary time evolution in the bulk. In this note we examine the prediction of holographic RG in de Sitter space for the flow of double and triple trace couplings in any proposed dual. We show quite generally that the correct form of the field theory beta functions for the double trace couplings is obtained from holography, provided one identifies the scale of the field theory with (i|T|) where T is the `time' in conformal coordinates. For dS(4), we find that with an appropriate choice of operator normalization, it is possible to have real n-point correlation functions as well as beta functions with real coefficients. This choice leads to an RG flow with an IR fixed point at negative coupling unlike in a unitary theory where the IR fixed point is at positive coupling. The proposed correspondence of Sp(N) vector models with de Sitter Vasiliev gravity provides a specific example of such a phenomenon. For dS(d+1) with even d, however, we find that no choice of operator normalization exists which ensures reality of coefficients of the beta-functions as well as absence of n-dependent phases for various n-point functions, as long as one assumes real coupling constants in the bulk Lagrangian.

description: Energy efficiency is the most important issue in all facets of wireless sensor networks (WSNs) operations because of the limited and non-replenish able energy supply. Data aggregation mechanism is one of the possible solutions to prolong the life time of sensor nodes and on the other hand it also helps in eliminating the data redundancy and improving the accuracy of information gathering, is essential for WSNs. In this paper we propose a Clustering based lifetime maximizing aggregation tree (CLMAT) in which we create aggregation tree which aim to reduce energy consumption, minimizing the distance traversed and minimizing the cost in terms of energy consumption. In CLMAT the node having maximum available energy is used as parent node/ aggregator node. We concluded with the best possible aggregation tree minimizing energy utilization, minimizing cost and hence maximizing network lifetime.

description: As a developing country, there are some challenges in Georgian Higher educational system that are related to equity, access and democratization. In addition to the students coming from ethnic minority groups (with no competences in Georgian language), the majority of the students comes from the peripheral areas and after moving to the big cities they need to work for paying their studies. Distance Education can be seen as a solution of the problems related to access on Higher education, for this reason this study aimed to find out what were the perceptions of the students and faculty members from the three universities (one from capital and two regional state HEIs). After collecting the data with using online surveys some focus groups and in-depth interviews were conducted with staff member, in order to discuss the students survey findings and hear more about teachers’ perceptions regarding the equity/access in Higher Education. The data collection was conducted fully online due to the pandemic (in April-June 2020). The results of the survey, together with the discussion and main findings are given in the following report

description: We study the dynamics of a tagged particle in an environment of point Brownian particles with hard-core interactions in an infinite one dimensional channel (a single-file model). In particular we examine the influence of initial conditions on the dynamic of the tagged particle. We compare two initial conditions: equal distances between particles and uniform density distribution. The effect is shown by the differences of mean-square-displacement and correlation function for the two ensembles of initial conditions. We discuss the violation of Einstein relation, and its dependence on the initial condition, and the difference between time and ensemble averaging. More specifically, using the Jepsen line, we will discuss how transport coefficients, like diffusivity, depend on the initial state. Our work shows that initial conditions determine the long time limit of the dynamic, and in this sense the system never forgets its initial state in complete contrast with thermal systems (i.e a closed system which attains equilibrium independent of the initial state).

description: We discuss the results of the analysis of multi-wavelength data for the afterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One of them, GRB 081007, also shows a spectroscopically confirmed supernova, SN 2008hw, which resembles SN 1998bw in its absorption features, while the maximum luminosity is only about half as large as that of SN 1998bw. Bright optical flashes have been detected in both events, which allows us to derive solid constraints on the circumburst-matter density profile. This is particularly interesting in the case of GRB 081007, whose afterglow is found to be propagating into a constant-density medium, yielding yet another example of a GRB clearly associated with a massive star progenitor which did not sculpt the surroundings with its stellar wind. There is no supernova component detected in the afterglow of GRB 090424, likely due to the brightness of the host galaxy, comparable to the Milky Way. We show that the afterglow data are consistent with the presence of both forward- and reverse-shock emission powered by relativistic outflows expanding into the interstellar medium. The absence of optical peaks due to the forward shock strongly suggests that the reverse shock regions should be mildly magnetized. The initial Lorentz factor of outflow of GRB 081007 is estimated to be Γ~ 200, while for GRB 090424 a lower limit of Γ> 170 is derived. We also discuss the prompt emission of GRB 081007, which consists of just a single pulse. We argue that neither the external forward-shock model nor the shock-breakout model can account for the prompt emission data and suggest that the single-pulse-like prompt emission may be due to magnetic energy dissipation of a Poynting-flux dominated outflow or to a dissipative photosphere.

description: Georgian higher education system has been gone through different phases of reforms after the country regained its independence in 1991. In this report the major directions of the GE Higher Education are explained – with an eye to the equity, access and democratization. Although there are different types of higher educational institutions each and every of them are going through the internal and external quality assurance measures before they are authorized by state. Students are enrolled at the university based on their scores in national exams, which was presented back in 2005. Higher education in general is not free, some students can get scholarships from state but the majority have to pay by themselves, thus affordability is an issue, especially on Masters and PhD levels. In addition to this, the majority of the students have to work at the same time of their studies, that is also an issue when speaking about the equity and accessibility.

description: We present a search for Higgs bosons in multilepton final states in pp-bar collisions at sqrt(s)=1.96 TeV recorded with the D0 detector at the Fermilab Tevatron Collider, using the full Run II data set with integrated luminosities of up to 9.7 fb-1. The multilepton states considered are two electron plus muon, electron with two muons, muon with two hadronic tau leptons, and like-charge electron-muon pairs. These channels directly probe the HVV (V=W,Z) coupling of the Higgs boson in production and decay. The muon with two hadronic tau lepton channel is also sensitive to H to tau lepton pair decays. Upper limits at the 95% C.L on the rate of standard model Higgs boson production are derived in the mass range 100 <= M_H <= 200 GeV. The expected and observed limits are a factor of 6.3 and 8.4 above the predicted standard model cross section at M_H=125 GeV. We also interpret the data in a fermiophobic Higgs boson model.

description: The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of Seyfert galaxies is a well established observational fact. This material is systematically outflowing and shows a large range in parameters. However, its actual nature and dynamics are still not clear. In order to gain insights into these important issues we performed a literature search for papers reporting the parameters of the soft X-ray warm absorbers (WAs) in 35 type 1 Seyferts and compared their properties to those of the ultra-fast outflows (UFOs) detected in the same sample. The fraction of sources with WAs is >60%, consistent with previous studies. The fraction of sources with UFOs is >34%, >67% of which also show WAs. The large dynamic range obtained when considering all the absorbers together allows us, for the first time, to investigate general relations among them. In particular, we find significant correlations indicating that the closer the absorber is to the central black hole, the higher the ionization, column, outflow velocity and consequently the mechanical power. The absorbers continuously populate the whole parameter space, with the WAs and the UFOs lying always at the two ends of the distribution. This strongly suggest that these absorbers, often considered of different types, could actually represent parts of a single large-scale stratified outflow observed at different locations from the black hole. The observed parameters and correlations are consistent with both radiation pressure through Compton scattering and MHD processes contributing to the outflow acceleration, the latter playing a major role. Most of the absorbers, especially the UFOs, have a sufficiently high mechanical power to significantly contribute to AGN feedback.

description: The competition between two ecologically similar species that use the same resources and differ from each other only in the type of spatial motion they undergo is studied. The latter is assumed to be described either by Brownian motion or Lévy flights. Competition is taken into account by assuming that individuals reproduce in a density-dependent fashion. It is observed that no influence of the type of motion occurs when the two species are in a well-mixed unstructured state. However, as soon as the species develop spatial clustering, the one forming more concentrated clusters gets a competitive advantage and eliminates the other. Similar competitive advantage would occur between walkers of the same type but with different diffusivities if this leads also to different clustering. Coexistence of both species is also possible under certain conditions.

description: The Israeli society is diverse, both ethnically and economically. Its population is composed of 22% non-Jewish minorities including Muslims, Bedouins, Christians and Druze, most living in low socio-economic locations. Among the Jewish majority, there are ultra-orthodox (8%) and Ethiopian-origin (1.5%) groups, as well as populations living in geographic and low socio-economic periphery. Such a diverse society brings challenges in terms of equity, access and democratization of higher education. The present report, performed for the Love.Dist@nce project aims to review and summarize the main practices and policies in Israel on this topic.

description: A modalidade de Ensino a Distância é cada vez mais uma condição sine qua non nos dias de hoje. O presente trabalho objetiva analisar a implementação das modalidades de ensino a distância e semipresencial em Angola. A metodologia desta investigação inscreve-se numa perspectiva qualitativa e empírico-descritiva, tendo como foco acontecimentos e contextos atuais (Covid-19). Considerando o objetivo e questão do estudo, foram adotadas, para a recolha de dados, as seguintes técnicas: análise documental, observação não participante e inquérito por questionário a professores. Com este estudo, constatou-se diversas barreiras para a implementação das Modalidades de Ensino a Distância e Semipresencial, como, por exemplo, as restrições de acesso a internet e a falta de condições técnicas, tecnológicas e de infraestruturas. Concluímos que se faça um investimento em todas as Instituições de Ensino Superior em Angola no que diz respeito ao acesso a internet, infraestruturas, apoio técnico e tecnológico e formação continuada em Tecnologia da Informação e da Comunicação aos docentes.

description: Moment approximation methods are gaining increasing attention for their use in the approximation of the stochastic kinetics of chemical reaction systems. In this paper we derive a general moment expansion method for any type of propensities and which allows expansion up to any number of moments. For some chemical reaction systems, more than two moments are necessary to describe the dynamic properties of the system, which the linear noise approximation (LNA) is unable to provide. Moreover, also for systems for which the mean does not have a strong dependence on higher order moments, moment approximation methods give information about higher order moments of the underlying probability distribution. We demonstrate the method using a dimerisation reaction, Michaelis-Menten kinetics and a model of an oscillating p53 system. We show that for the dimerisation reaction and Michaelis-Menten enzyme kinetics system higher order moments have limited influence on the estimation of the mean, while for the p53 system, the solution for the mean can require several moments to converge to the average obtained from many stochastic simulations. We also find that agreement between lower order moments does not guarantee that higher moments will agree. Compared to stochastic simulations our approach is numerically highly efficient at capturing the behaviour of stochastic systems in terms of the average and higher moments, and we provide expressions for the computational cost for different system sizes and orders of approximation. {We show how the moment expansion method can be employed to efficiently {quantify parameter sensitivity}.} Finally we investigate the effects of using too few moments on parameter estimation, and provide guidance on how to estimate if the distribution can be accurately approximated using only a few moments.

UNBOXING GOTH: THE WORK OF SUBCULTURAL REPRODUCTION AND COMMODIFICATION

description: This thesis uses a mixed critical/qualitative approach to understand how goth subculture is constructed and commodified in goth nightclubs and on YouTube. The framework is guided by Bourdieu’s theories of cultural production and social capital, critiques of digital labor, and scholarship on subcultures. I investigate how the mainstreaming of a subculture through media and fashion is negotiated by self-identified participants in the subculture. In the critical-cultural section, I analyze clothing haul videos from three popular goth YouTubers (It’s Black Friday, Toxic Tears, and Angela Benedict). As cultural mediators, they perform subcultural capital for a wider audience that includes a mix of newcomers, old timers, and the simply curious. Each account presents a different model for translating among subcultural, social, economic, and symbolic capital. Although they all perform digital labor, they differentially prioritize and communicate typical aspects of goth identity. For the qualitative portion, I conducted ten semi-structured interviews with active participants of the Southern California goth club scene. I uncovered how the participants negotiated their identity performance off- and on- line. Commodification and consumerism play a significant role in the way identity is created and maintained in online spaces, and less so offline. In the final chapter, I integrate critical and qualitative findings. Together, these findings illuminate contradictions between the work of digital labor that translates among different forms of capital and the work of subcultural reproduction, or performing, educating, and modeling tacit and implicit values. This thesis contributes to scholarship on subcultures, labor, and digital media.
