Magnesium-lime process for decolourization of kraft mill effluents
Creators: name: Rush, Richard John
Publisher: name: University of British Columbia
Year: 2010

description: A magnesium-plus-lime coagulation process, incorporating magnesium recovery by sludge carbonation, recently developed for water treatment has been tested for its application to the decolourization of kraft mill effluents. Total bleached kraft mill effluent (BKME), after biological treatment and effluent from the first caustic extraction stage of a conventional bleachery (E₁ or T-20 effluent) were examined in the laboratory. It was shown that a combination of low magnesium and low lime dosages can achieve better decolourization of kraft mill effluents than 3-5 times as much lime alone, (i.e.: 30-60 mg/1 Mg⁺⁺ plus 375-475 mg/1 lime (as Ca0) at pH ≃11.1 for BKME; and 150-300 mg/1 Mg⁺⁺ plus 1875-3750 mg/1 lime (as Ca0) at pH ≃12.1 for T-20 effluent.) Colour removals of 90-95% were achieved using either fresh or recycled magnesium. Results of the study showed that greater than 90% magnesium recovery can be attained by operating the sludge carbonator to a final pH ≃7.5, with complete mixing and a good C02 diffuser system provided.

title: Evaluation of Alternative Non-Animal Approaches for the Prediction of Skin Sensitisation Potential of Agrochemicals
Creators: name: Masinja, H

description: Skin sensitisation in humans is an important toxicological effect to be determined should there be frequent and prolonged exposure. Current approaches to assessing skin sensitisation mostly utilise in vivo testing, although there is a move to alternatives such as in silico, in chemico and in vitro approaches. The aim of this thesis was to investigate whether these alternative approaches could be utilised for agrochemical active ingredients (AIs) and formulations. Agrochemicals represent a unique problem for risk assessment due to the high level of regulatory compliance required in addition to the intrinsic issues of assessing formulations. Using the in vivo experimental results as a benchmark, the overall sensitivity and specificity of the Classification Labelling and Packaging (CLP) threshold calculation method, regardless of agrochemical formulation type, were determined to be 58% and 82% respectively. Thus, for the plant production products (PPPs) assessed, the threshold method had a high probability of accurately predicting non-sensitisers. To supplement the information, the in vitro triple pack (Direct Peptide Reactivity Assay, KeratinoSensTM and h-CLAT) was applied using established Integrated Testing Strategies and Defined Approaches. Overall, the triple pack performed poorly for the assessment of AIs and formulations alike. The Genomic Allergen Rapid Detection (GARD) assay for the ten AIs showed a high sensitivity but a low total accuracy; the sensitivity was 0% with the in vivo non-sensitisers being predicted as sensitisers in the GARD assay. Eight of the ten PPPs tested in the SENS-IS assay produced results that were in good agreement with the vertebrate study outcomes. Findings from investigations into the Two Dimensional (2D) in vitro test methods demonstrated that testing of complex mixtures in those models could not be conducted accurately with current methods. Use of the SENS-IS method allowed for direct application of the PPP to the Reconstructed Human Epidermis (RhE) test system so that good comparison to the products intended and anticipated use can be made. It is envisaged that the work conducted in this thesis will add to the toxicology research conducted on skin sensitisation thus far and be of use primarily for decision making in hazard assessment of agrochemicals.

description: Study of condensed matter in certain extreme conditions allows one to better understand the mechanisms of microscopic structural transformations and to develop materials with completely new mechanical properties. In the present work, we study the structure and crystallization kinetics of bulk metallic glass (BMG) Ni$_{62}$Nb$_{38}$. We show that this BMG is rapidly crystallized under the combined effect of shear deformation and ultrahigh pressure. A threshold pressure required to initiate the formation of a stable crystalline phase is revealed. Shear deformation and pressure lead to the phase separation: two high-density inhomogeneous crystal structures are formed. We find that the crystallization of this BMG occurs in two stages due to the significant difference in the growth rates of Ni and Nb crystalline phases. The results of the present study make a significant contribution to understanding the crystallization and amorphization features of Ni-based BMG's.

description: В статье рассмотрена кинематическая модель преследования одиночной цели группой преследователей методом параллельного сближения, основанная на том, что преследователи стараются придерживаться заранее спроектированных траекторий. Траектории преследователей имеют ограничения по кривизне. Начальные направления скоростей преследователей имеют произвольный характер, что вносит изменения в известный метод параллельного сближения. Цель в модели достигается преследователями одновременно из-за изменения длины прогнозируемых траекторий путем синхронизации времени. Изменение длины происходит за счет увеличения радиуса кривизны на первоначальном участке траектории.
description: The article discusses a kinematic model of a group pursuing a single target by the method of parallel approach. The model is based on the fact that pursuers try to stick to pre-designed trajectories. The pursuer’s trajectories have curvature constraints. The initial directions of the pursuers’ velocities are arbitrary, which changes the well-known method of the parallel approach. In our model, the goal is achieved by the pursuers simultaneously. This is due to the change in the lengths of the predicted trajectories by time synchronization to reach the target. The change in length occurs due to an increase in the radius of curvature in the initial section of the trajectory.
Volatile organic components of municipal primary sewage effluent after chlorination and dechlorination
Creators: name: Mori, Brian Tomio
Publisher: name: University of British Columbia
Year: 2010

description: The extraction, separation and identification of volatile organic components of primary effluent before and after chlorination was undertaken to ascertain whether the chlorination of treatment plant effluents results in the formation of new volatile chlorinated organics. Extraction efficiencies of 70 to 90 percent of an aqueous solution of phenols were obtained by both continuous solvent extraction and sorption on a column of a macroreticular resin. Tests with primary effluent showed that the macroreticular resin recovered a slightly larger number of compounds than the solvent extractor which also suffered from emulsion problems.' Since the resin was also expedient in handling replicate samples it was adopted and further studies indicated that it had a capacity of 1.7 mg TOC/cc of resin and recoveries of the phenols were unaffected by pH or detergents. Preliminary separation of the. .components on the basis of acidity with .05'M^NaOH and diethyl ether and by thin layer chromatography on silica gel with pet ether and methanol proved to be useful. Gas chromatographic (GC) studies with various silicone liquid phases demonstrated that OV-101, 0V-17, and 0V-225 all provide good separation after optimization of temperature programs. Primary effluent samples taken from Lion's Gate Treatment Plant in North Vancouver on Monday mornings proved to be remarkably consistent in their GC 63 traces as monitored by Ni electron capture (EG) and flame ionization (FID) detectors. A series of spectacular new peaks was consistently observed by EC as a result of chlorination, but the FID showed only minor changes. Dosage levels of up to 120 mg/1 Cl₂ (NaOCl) produced similar chromatograms while a dosage of 200 mg/1 produced a new set of changes not found at the dosage levels used in treatment plants. Gas chromatographic studies with a micro- electrolytic conductivity detector showed that 10 or 11 new halogenated peaks in the neutral and basic fraction and 6 or 7 new halogenated peaks in the acidic fraction result from chlorination. These compounds all of which are in μg/l concentrations account for only 0.01 percent of the applied chlorine dosage but make up about 40 percent of the more volatile organically bound halogen present in chlorinated primary effluent. After a series of partially successful attempts by retention time, GC-MS and GC effluent trapping, a number of components were positively identified by a computerized GC-MS. TRirty-one compounds were positively identified by mass spectra and GC retention times, another 24 were tentatively identified by mass spectra and an additional seven were very tentatively identified by GC retention times. Only three of the compounds resulting from chlorination were positively identified. All compounds identified by mass spectra are present in concentrations in primary effluent. The implications of this study and suggestions for further investigations are also discussed.

description: In the last few decades, theoretical and experimental studies of glass-forming liquids have revealed presence of universal regularities in the viscosity-temperature data. In the present work, we propose a viscosity model for scaling description of experimental viscosity data. A feature of this model is presence of only two adjustable parameters and high accuracy of experimental data approximation by this model for a wide temperature range. The basis of the scaling description is an original temperature scale. Within this scaling description we obtain the transformed Angell plot, in which the area separating "fragile" and "strong" glass-formers emerges. The proposed scaling procedure make it possible to reconsider belonging some liquids to the type of "fragile" glass-formers. The obtained results form basis for development of a generalized scaling description of crystallization kinetics in supercooled liquids and glasses.

description: The biexciton cascade in a quantum dot can be used to generate entangled-photon pairs rapidly and deterministically (on demand). However, due to a large fine-structure splitting between intermediate exciton energy levels, which-path information encoded in the frequencies of emitted photon pairs leads to a small degree of entanglement. Here we show that this information can be efficiently erased by modulating the exciton and biexciton energy levels, giving rise to new decay paths through additional sidebands. The resulting degree of entanglement is substantial, and can be made maximal through spectral filtering, with only a nominal reduction in collection efficiency.

Autonomy and the moral agent
Creators: name: Partridge, Yolande Mary
Publisher: name: University of British Columbia
Year: 2010

description: The development of personal autonomy is often considered to be an important objective of education in general, and moral education in particular. This paper is an attempt to clarify what is meant by the concept of personal" autonomy, to justify its promotion as a personal and educational ideal, and to examine the connection between personal autonomy and moral agency. Four conditions are found to be necessary for the possession and exercise of personal autonomy: freedom of choice, authenticity, rational reflection and strength of will. The promotion of personal autonomy is justified on at least four kinds of grounds: for its extrinsic value, for its intrinsic worth, for its educational significance, and for its close conceptual connection with the notion of moral agency. The criterion of 'relating to other people's interests' is taken to be the most important factor in distinguishing between ordinary autonomous acts and acts of moral agency.

description: We study optimal contracts offered by two firms competing for the exclusive services of one worker, who is privately informed about her ability and her motivation. Firms differ both in their production technology and in the mission they pursue and a motivated worker is keen to be hired by the missionoriented firm. We find that the matching of worker types to firms is always Pareto-efficient. When the difference in firms’ technology is high, only the most efficient firm is active. When the difference is not very high, then agent types sort themselves by motivation: the mission-oriented firm hires motivated types and the profit-oriented firm employs non-motivated ones, independently of ability. Effort provision is higher when the worker is hired by the mission-oriented firm, but a compensating wage differential might exist: the motivated worker is paid less by the mission-oriented firm. Such an earnings penalty is driven entirely by motivation and is increasing in ability.

Predictive powers of chiral perturbation theory in Compton scattering off protons

description: We study low-energy nucleon Compton scattering in the framework of baryon chiral perturbation theory (B$χ$PT) with pion, nucleon, and $Δ$(1232) degrees of freedom, up to and including the next-to-next-to-leading order (NNLO). We include the effects of order $p^2$, $p^3$ and $p^4/\varDelta$, with $\varDelta\approx 300$ MeV the $Δ$-resonance excitation energy. These are all "predictive" powers in the sense that no unknown low-energy constants enter until at least one order higher (i.e, $p^4$). Estimating the theoretical uncertainty on the basis of natural size for $p^4$ effects, we find that uncertainty of such a NNLO result is comparable to the uncertainty of the present experimental data for low-energy Compton scattering. We find an excellent agreement with the experimental cross section data up to at least the pion-production threshold. Nevertheless, for the proton's magnetic polarizability we obtain a value of $(4.0\pm 0.7)\times 10^{-4}$ fm$^3$, in significant disagreement with the current PDG value. Unlike the previous $χ$PT studies of Compton scattering, we perform the calculations in a manifestly Lorentz-covariant fashion, refraining from the heavy-baryon (HB) expansion. The difference between the lowest order HB$χ$PT and B$χ$PT results for polarizabilities is found to be appreciable. We discuss the chiral behavior of proton polarizabilities in both HB$χ$PT and B$χ$PT with the hope to confront it with lattice QCD calculations in a near future. In studying some of the polarized observables, we identify the regime where their naive low-energy expansion begins to break down, thus addressing the forthcoming precision measurements at the HIGS facility.

description: Following the dreamlike symbolic image of lilac plant we will retrace the exile pathway of María Zambrano from Europe to Latin America and back again through inextricable memories of historical events, personal experiences and dreams. We will examine the existential and philosophical experience of exile as death and rebirth (desnacimento). Thanks to distance and separation from motherland, Zambrano could go through the radical dereliction that brought her to the inner solitude of the self. So that she could discover the function of delirium as a salvific force: the resistance of the past overcoming the ruins of history and opening to a new future. Therefore the misfortune of exile turns into good fortune and the outcasts become, in Zambrano’s words, “the beatified persons (los bienaventurados)”.

Kimsey & Bohart (1991: 427) synonymised C. rubroviolacea Mocsáry, 1913, described from South Africa, with C. jousseaumei, described from Djibouti. Chrysis jousseaumei is characterised by toothed mesopleuron (Fig. 7C), violet to purplish body colour, large punctures with polished interspaces covering the whole body (Fig. 7E). Chrysis rubroviolacea, as correctly given in the original description, has a simple, unmodified mesopleuron, without any evident tooth (Fig. 7D); in addition, the shape of the head is different (Fig. 7B), being clearly transverse (l/w = 0.7) (measure taken from the transverse frontal carina to clypeal margin) and the shortest distance between inner eye margin instead of triangular, and short (l/w = 0.8) as in C. rubroviolacea (Fig. 7A); the episternal sulcus is formed by larger foveae (Fig. 7D); the black spots on second sternum are narrower, almost half as wide as long. For these notable differences in diagnostic characters, we consider C. rubroviolacea Mocsáry, 1913 as a valid species.

description: Long-lived magnetic fields are known to exist in upper main-sequence stars, white dwarfs, and neutron stars. In order to explore possible equilibrium configurations of the magnetic field inside these stars, we have performed 3D-magnetohydrodynamic simulations of the evolution of initially random magnetic fields in stably stratified and barotropic stars with an ideal-gas equation of state using the {\sc Pencil Code}, a high-order finite-difference code for compressible hydrodynamic flows in the presence of magnetic fields. In barotropic (isentropic) stars, we confirm previous results in the sense that all initial magnetic fields we tried decay away, unable to reach a stable equilibrium. In the case of stably stratified stars (with radially increasing specific entropy), initially random magnetic fields appear to always evolve to a stable equilibrium. However, the nature of this equilibrium depends on the dissipation mechanisms considered. If magnetic diffusivity (or hyperdiffusivity) is included, the final state is more axially symmetric and dominated by large wavelengths than the initial state, whereas this is not the case if only viscosity (or hyperviscosity) is present. In real stars, the main mechanism allowing them to relax to an equilibrium is likely to be phase mixing, which we argue is more closely mimicked by viscosity. Therefore, we conclude that, depending on its formation mechanism, the equilibrium magnetic field in these stars could in principle be very asymmetric.

description: Similar to other parts of the world, Kurdish speakers of English have been subject to English fever. They have a strong desire to learn and speak English. An army of teachers is currently teaching Kurdish speakers to learn English. However, few of them acquire the required level of English when they move from high school level to university one. This might partly be associated with their attitudes towards not only the English language but the English language policies and practices that are currently adopted. Attitudes towards the English language have been extensively investigated both quantitatively and qualitatively in diversified educational and cultural contexts. Furthermore, a few studies have been conducted to investigate the attitudes of Kurdish students towards the English language, but their attitudes to English language education policies and English language learning purposes have yet remained unknown. Therefore, this study is anchored on investigating Kurdish undergraduate students’ attitudes towards the English language, English language education policies that are currently applied in Iraqi Kurdistan, and students’ purposes for learning English. It further concentrates on the effect of such variables as gender and year of study on attitudes. For this purpose, the study utilized a questionnaire consisting of 42 items on a 6-point Likert scale surveyed online on a sample of 154 students belonging to different ages, genders, years of study, and majors. The analysis of the data showed that Kurdish university students held neutral to mildly positive attitudes to the English language and English learning purposes. Nevertheless, they held slightly positive attitudes towards English language education policies. The study concludes that, although fundamental transformations have been achieved in the past two decades, the neutral attitudes show that efforts are yet to be made to satisfy students’ needs and desires, particularly with regard to the policies and practices that are currently adopted. This study, different from previous ones, reveals students’ attitudes towards English education policies whose findings are significant for English language education policymakers.

description: We combine the CfA3 supernova Type Ia (SN Ia) sample with samples from the literature to calculate improved constraints on the dark energy equation of state parameter, w. The CfA3 sample is added to the Union set of Kowalski et al. (2008) to form the Constitution set and, combined with a BAO prior, produces 1+w=0.013 +0.066/-0.068 (0.11 syst), consistent with the cosmological constant. The CfA3 addition makes the cosmologically-useful sample of nearby SN Ia between 2.6 and 2.9 times larger than before, reducing the statistical uncertainty to the point where systematics play the largest role. We use four light curve fitters to test for systematic differences: SALT, SALT2, MLCS2k2 (R_V=3.1), and MLCS2k2 (R_V=1.7). SALT produces high-redshift Hubble residuals with systematic trends versus color and larger scatter than MLCS2k2. MLCS2k2 overestimates the intrinsic luminosity of SN Ia with 0.7 < Delta < 1.2. MLCS2k2 with R_V=3.1 overestimates host-galaxy extinction while R_V=1.7 does not. Our investigation is consistent with no Hubble bubble. We also find that, after light-curve correction, SN Ia in Scd/Sd/Irr hosts are intrinsically fainter than those in E/S0 hosts by 2 sigma, suggesting that they may come from different populations. We also find that SN Ia in Scd/Sd/Irr hosts have low scatter (0.1 mag) and reddening. Current systematic errors can be reduced by improving SN Ia photometric accuracy, by including the CfA3 sample to retrain light-curve fitters, by combining optical SN Ia photometry with near-infrared photometry to understand host-galaxy extinction, and by determining if different environments give rise to different intrinsic SN Ia luminosity after correction for light-curve shape and color.

description: Although frequency multiplexing of information has revolutionized the field of classical communications, the color degree of freedom (DOF) has been used relatively little for quantum applications. We experimentally demonstrate a new hybrid quantum gate that transfers polarization entanglement of non-degenerate photons onto the color DOF. We create, for the first time, high quality, discretely color-entangled states (with energy bandgap up to 8.4 THz) without any filtering or postselection, and unambiguously verify and quantify the amount of entanglement (tangle, 0.611$\pm$0.009) by reconstructing a restricted density matrix; we generate a range of maximally entangled states, including a set of mutually unbiased bases for an encoded qubit space. The technique can be generalized to transfer polarization entanglement onto other photonic DOFs, like orbital angular momentum.

description: The aim of the article to clarify the status of Shapiro plane wave solutions of the Schrödinger's equation in the frames of the well-known general method of separation of variables. To solve this task, we use the well-known cylindrical coordinates in Riemann and Lobachevsky spaces, naturally related with Euler angle-parameters. Conclusion may be drawn: the general method of separation of variables embraces the all plane wave solutions; the plane waves in Lobachevsky and Riemann space consist of a small part of the whole set of basis wave functions of Schrödinger equation. In space of constant positive curvature $S_{3}$, a complex analog of horospherical coordinates of Lobachevsky space $H_{3}$ is introduced. To parameterize real space $S_{3}$, two complex coordinates $(r,z)$ must obey additional restriction in the form of the equation $r^{2} = e^{z-z^{*}} - e^{2z} $. The metrical tensor of space $S_{3}$ is expressed in terms of $(r,z)$ with additional constraint, or through pairs of conjugate variables $(r,r^{*})$ or $(z,z^{*})$; correspondingly exist three different representations for Schrödinger Hamiltonian. Shapiro plane waves are determined and explored as solutions of Schrödinger equation in complex horosperical coordinates of $S_{3}$. In particular, two oppositely directed plane waves may be presented as exponentials in conjugated coordinates. $Ψ_{-}= e^{-αz}$ and $Ψ_{+}= e^{-αz^{*}}$. Solutions constructed are single-valued, finite, and continuous functions in spherical space and correspond to discrete energy levels.

A Gluon Transverse Momentum Dependent Parton Distribution Function Analysis Using a J/Ψ + γ Final State at √s = 13 TeV with ATLAS
Creators: name: Tee, Amy
Publisher: name: Lancaster University
Year: 2021

description: This thesis describes a study into Transverse-Momentum-Dependent (TMD) distributions of gluons inside a proton, through a J/ψ meson plus γ final state. The analysis was performed using 2.57 fb−1 of data collected by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV in 2015. A measurement of the continuum J/ψ+γ cross section is carried out, in order to give access to the TMD function fg1(k2T), which describes the distribution of unpolarised gluons in an unpolarised proton. Assuming a Gaussian shape of the TMD distribution, with dependence on the intrinsic transverse momentum of a gluon, kT, a measurement of the mean transverse momentum was achieved at three different invariant mass ranges, Q, of the J/ψ−γ system. The invariant mass ranges, and measured values of ⟨k2T⟩−−−−√ are summarised as follows: for 15 ≤Q< 22 GeV, the mean gluon transverse momentum was found to be ⟨k2T⟩−−−−√ = 1.99 ± 0.25 GeV. For the second invariant mass range considered 22 ≤Q< 31 GeV giving ⟨k2T⟩−−−−√ = 3.63 ± 0.41 GeV. For the last (upper) invariant mass range considered 31 ≤Q< 44 GeV, it was found that 4.08 ± 0.74 GeV. It is shown that between the lowest and highest invariant mass ranges considered, the intrinsic mean transverse momentum of gluons inside an unpolarised proton increases by a factor of 2. The second measurement was an attempt to measure the contribution of the TMD function h⊥g1(k2T), which describes the distribution of linearly polarised gluons inside an unpolarised proton. By measuring the induced angular azimuthal modulations expected from interacting polarised gluons no statistically significant modulation was found with the dataset used.
Real-time computer recognition of handprinted characters

description: A real-time character recognition system was developed to recognize upper case handprinted characters in a real-time small machine environment. The recognition system consists of two major components: namely, a data acquisition system and a pattern recognition system. The data acquisition system was designed and implemented to allow the real world data flow into the computer from a COMPUTER writing tablet in real time. The pattern recognition system was also designed and implemented to yield a decision on the input character in real time (user time). A curve optimization technique originally devised by Reumann and Witkam was modified to extract only the significant data that describes a character. Computations were minimized through mathematical simplifications, hardware-software trade-off, and special programming techniques at the machine level. In addition, the preprocessor operated concurrently with the data acquisition routine to reduce data storage requirements as well as to-provide fast response to handprinted inputs. A non-uniform quantization plane was proposed and implemented to discriminate pen directions. Stroke patterns of a character were recognized using a syntactic approach. Finally, recognized stroke patterns within a character were classified as one of the known pattern classes by two classification methods: dictionary look-up and a modified nearest neighbor rule, both guided by special geometric measurements on some character pairs. Character patterns were defined in the dictionary such that no user training or personalized dictionary is required for future use. A test was conducted using the ACM proposed upper case handprinted character set and a recognition rate of 98.3% was obtained from over 2300 characters of sizes varying from 1/4 inch tall to 3/4 inch tall from 10 people. It Is observed that the approach taken in this thesis can also be applied to recognized handprinted patterns other than the standard one proposed by the ACM.
title: Das Frauenbild der Nationalsozialisten in der Bildpropaganda
Creators: name: Yildiz, Sümeyye
Year: 2023

description: Die Nationalsozialisten hatten eine bestimmte Vorstellung davon, wie eine deutsche Frau zu sein hatte. Um dieses Ideal in die Realität umzusetzen, wurden viele unterschiedliche Maßnahmen getroffen. Das nationalsozialistische Frauenbild wurde unter anderem auch durch Bildquellen vermittelt und propagiert. Dabei stand die Mutterrolle deutlich im Vordergrund. Der Mutterkult hat zu Zeiten der Nationalsozialisten einen erheblichen Aufschwung erlebt und wurde stark in den Mittelpunkt gestellt. Erst im Lauf des Zweiten Weltkrieges wurde von dieser Vorstellung abgewichen, da die Tätigkeit der Frauen nun auch in anderen kriegswichtigen Bereichen notwendig war. Es kann also gesagt werden, dass das propagierte Frauenbild im Krieg einen Widerspruch erlebt hat und nun „ideale“ deutsche Frauen auch jene Aufgaben ausgeübt haben, die davor, laut den Nationalsozialisten, dem „Wesen“ einer Frau widersprachen. Genau diese Thematik wird auch in dieser Masterarbeit behandelt. In einem Kapitel werden auch Bildquellen angeführt, anhand derer der Wandel des Frauenbildes gezeigt werden möchte. Zudem wird das Thema mittels Literaturrecherche nicht nur fachwissenschaftlich behandelt. In einem Kapitel der Masterarbeit wird die Thematik auch für den Unterricht aufbereitet und aus der fachdidaktischen Perspektive thematisiert. Die Bedeutung der Bildquellen für den Geschichtsunterricht wird geschildert. In diesem Zusammenhang wurden auch ein eigenes Unterrichtskonzept sowie Materialien für den Geschichtsunterricht erstellt. Diese sollen zeigen, wie das Thema der Masterarbeit im Geschichtsunterricht behandelt und umgesetzt werden könnte.

description: In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have limited bandwidth, delay estimation using these algorithms often leads to poor localization performance. To mitigate these constraints, we exploit the multiband and carrier frequency switching capabilities of wireless transceivers and propose to acquire channel state information (CSI) in multiple bands spread over a large frequency aperture. The data model of the acquired measurements has a multiple shift-invariance structure, and we use this property to develop a high-resolution delay estimation algorithm. We derive the Cramér-Rao Bound (CRB) for the data model and perform numerical simulations of the algorithm using system parameters of the emerging IEEE 802.11be standard. Simulations show that the algorithm is asymptotically efficient and converges to the CRB. To validate modeling assumptions, we test the algorithm using channel measurements acquired in real indoor scenarios. From these results, it is seen that delays (ranges) estimated from multiband CSI with a total bandwidth of 320 MHz show an average RMSE of less than 0.3 ns (10 cm) in 90% of the cases.

Historical analysis on the evolution of migration and integration narratives. British-French narratives to restrict immigration from the Global South, 1960s-mid-1980s.

description: This Working Paper identifies five prominent transnational narratives in France and the UK that aimed to justify restrictions towards immigrants from the Global South, from the 1960s to the mid-1980s, when both countries turned to restrictive policies structurally. France and the UK were the most exposed to large and autonomous migration flows from the Global South as a result of their former colonial empires.
 Parliamentary debates in the House of Commons and the French Senate, articles from British, French, and American newspapers, including a local French newspaper, and public speeches allow reporting an invasion narrative, a difference narrative, a humanitarian narrative, an oil-shock narrative, and a crisis narrative. The humanitarian narrative – presenting migrants as victims to protect – and the crisis narrative – putting forward insurmountable economic difficulties to curb immigration – became the most
 successful to justify state intervention to restrict immigration as they matched native workers’ concerns while minimising disturbances within destination countries.
