description: The analysis of the electronic surface properties of transition metal oxides being key materials for future nanoelectronics requires a direct characterization of the conductivity with highest spatial resolution. Using local conductivity atomic force microscopy (LC-AFM) we demonstrate the possibility of recording current maps with true atomic resolution. The application of this technique on surfaces of reduced TiO$_2$ and SrTiO$_3$ reveals that the distribution of surface conductivity has a significant localized nature. Assisted by density functional theory (DFT) we propose that the presence of oxygen vacancies in the surface layer of such materials can introduce short range disturbances of electronic structure with confinement of metallic states on the nanoscale.

description: Die (filmwissenschaftliche) Forschung zum Female Gaze, losgelöst vom Male Gaze, fand direkt nach Mulvey (1975, 1981) keinen nennenswerten Anlauf. Erst 2016 nahm sich Soloway (2016) dem Female Gaze an und formulierte in seiner Aktualisierung und Konzeptualisierung inhaltliche sowie filmpraktisch ausgelegte Anleitungen und Handlungsanweisungen. Die vorliegende Bachelorarbeit widmet sich der Frage, wie sich dieser Female Gaze (Soloway, 2016) im Film ausgestaltet und welchen Machtdynamiken er folgt. Die hierbei angeführten filmpraktischen Anleitungen und Handlungsanweisungen werden mittels Szenenanalysen aus 고양이를 부탁해 [engl. TAKE CARE OF MY CAT] (Jeong, Südkorea 2001), PORTRAIT DE LA JEUNE FILLE EN FEU [dt. PORTRÄT EINER JUNGEN FRAU IN FLAMMEN] (Sciamma, Frankreich 2019) und FLEABAG (Kirkby & Bradbeer, GB 2016 & 2019) auf ihre Tauglichkeit überprüft. Darüber hinaus wird sich ebenfalls der Frage gewidmet, wie es sich mit Filmen außerhalb des Male Gaze und Female Gaze verhält. Diese, außerhalb der Normativität bestehende Existenz, wird anhand einer Szenenanalyse aus MOONLIGHT (Jenkins, USA 2016) erörtert. Spätestens an dieser Stelle wird deutlich, dass die bisherigen Konzepte Mulveys (1975, 1981) und Soloways (2016) nur über bedingte Tragweite verfügen und einer Umformulierung, Erweiterung und Anpassung im Sinne weiterer Inklusion bedürfen. Diese Fehlstellung in der Forschung wird mittels eines hier zusammengebrachten Vorschlags Vissers (1997) und Fleischmanns (2016) hinsichtlich eines dem Female Gaze überspannenden Bogens zu Gunsten eines umfassenden Feminist Gaze versus Patriarchal Gaze begegnet. Schließlich wird diesem tatsächlich das Potential zugesprochen eine Auf-, beziehungsweise Durchbrechung bestehender asymmetrischer Machtstrukturen, wie sie der Blick auf und im Film reproduziert, aufrechterhält, normalisiert und fortführt, vorzunehmen.

description: In this paper, we discussed the multiple vector fields during the inflation era and the inflationary magnetogenesis with multiple vector fields. Instead of a single coupling function in single vector field models, the coupling matrix between vector fields and scalar field which drive the inflation is introduced. The dynamical equations for multiple vector fields are obtained and applied to the inflation era. We discussed three cases for the double-field model. In no mutual-coupling case, one can find that both electric and magnetic spectrum can be scale-invariant at the end of inflation, meanwhile, the strong coupling problem can be avoided. The effect of mutual-coupling between different vector fields is also discussed. We found that weak mutual-coupling can lead to the slightly blue spectrum of the magnetic field. On the other hand, in the strong mutual-coupling case, the scale-invariant magnetic spectrum can also be obtained but the energy density of electromagnetic fields either lead to the backreaction problem or is diluted by inflation.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The main purpose of this study is to analyze the thermo-mechanical behavior of the dry contact between the brake disc and pads under different speed and load of the AA-LRT train during emergency braking. CATIA software was used for the modeling purpose. The thermo-mechanical analysis of the disc brake was carried out using ANSIS workbench. In this work, a transient thermal and structural analysis was carried out to investigate the temperature variation across the disc, total heat flux using ANSYS software. The thermal-structural analysis is then used to determine the deformation established and stresses in the disk. And also the life time of the disc was analyzed using ANSIS workbench. In all cases as vehicle speed and load of the vehicle increases both temperature and Total heat flux increases. But For a constant speed of vehicle as the load increases both the Equivalent stress and Total deformation increases. But if speed of the vehicle increases both Equivalent stress and Total deformation increases for all loads. As the load and speed of the vehicle increases the life time of the vehicle decreases. Moving the train with speed of 22.342 m/s shortens the life disc brake.

description: In some quantum many particle systems, the fermions could form Cooper pairs by exchanging intermediate bosons. This then drives a superconducting phase transition or a superfluid transition. Such transitions should be theoretically investigated by using proper non-perturbative methods. Here we take the neutron superfluid transition as an example and study the Cooper pairing of neutrons mediated by neutral $π$-mesons in the low density region of a neutron matter. We perform a non-perturbative analysis of the neutron-meson coupling and compute the pairing gap $Δ$, the critical density $ρ_{c}$, and the critical temperature $T_c$ by solving the Dyson-Schwinger equation of the neutron propagator. We first carry out calculations under the widely used bare vertex approximation and then incorporate the contribution of the lowest-order vertex correction. This vertex correction is not negligible even at low densities and its importance is further enhanced as the density increases. The transition critical line on density-temperature plane obtained under the bare vertex approximation is substantially changed after including the vertex correction. These results indicate that the vertex corrections play a significant role and need to be seriously taken into account.

description: A interação com os jogos digitais faz parte do cotidiano de muitas crianças, especialmente como atividade de entretenimento e interação social em jogos on-line ou comunidades de jogadores. Este estudo tem como objetivo caracterizar o consumo midiático de jogos digitais de crianças do 6º ano do Ensino Fundamental, procurando identificar o que elas percebem e o que aprendem na interação com os jogos digitais, destacando o papel da família no controle e na mediação desse acesso. Para tanto, foi realizada uma pesquisa exploratória com abordagem mista, utilizando como procedimento de coleta de dados a aplicação de um questionário que foi respondido por 59 crianças. Os resultados relevaram que 48,28% das crianças acessam de 1 a 2 horas por dia jogos digitais e 17,24% mais que 8 horas; encontrou-se associação entre o tempo que indicam jogar e o controle dos pais sobre o tempo de acesso à internet, indicando que quanto o controle pode reduzir o tempo de tela jogando. Em relação ao que aprendem, destacaram-se as habilidades cognitivas e a aprendizagem sobre o próprio jogo. A partir disso, reforça-se a importância da mediação e orientação das crianças, tanto no âmbito familiar como escolar, sobre o acesso ao jogo para potencializar suas contribuições à aprendizagem.

description: In the context of fast developing quantum technologies, locating single quantum objects embedded in solid or fluid environment while keeping their properties unchanged is a crucial requirement as well as a challenge. Such "quantum microscopes" have been demonstrated already for NV-centers embedded in diamond [1], and for single atoms within an ultracold gas [2]. In this work, we demonstrate a new method to determine non-destructively the position of randomly distributed semiconductor quantum dots (QDs) deeply embedded in a solid photonic waveguide. By setting the wire in an oscillating motion, we generate large stress gradients across the QDs plane. We then exploit the fact that the QDs emission frequency is highly sensitive to the local material stress [3-5] to infer their positions with an accuracy ranging from +/- 35 nm down to +/-1 nm for close-to-axis QDs.

description: We present a robust adaptive model predictive control (MPC) framework for nonlinear continuous-time systems with bounded parametric uncertainty and additive disturbance. We utilize general control contraction metrics (CCMs) to parameterize a homothetic tube around a nominal prediction that contains all uncertain trajectories. Furthermore, we incorporate model adaptation using set-membership estimation. As a result, the proposed MPC formulation is applicable to a large class of nonlinear systems, reduces conservatism during online operation, and guarantees robust constraint satisfaction and convergence to a neighborhood of the desired setpoint. One of the main technical contributions is the derivation of corresponding tube dynamics based on CCMs that account for the state and input dependent nature of the model mismatch. Furthermore, we online optimize over the nominal parameter, which enables general set-membership updates for the parametric uncertainty in the MPC. Benefits of the proposed homothetic tube MPC and online adaptation are demonstrated using a numerical example involving a planar quadrotor.

Analyzing the Determinants of Farmers' Preference for Adaptation Strategies to Climate Change: Evidence from North Shoa Zone of Amhara Region
Creators: name: Mulatu, Negash
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Studies on climate change adaptation recognize the importance of agro-ecology based research for designing context-specific policies and programs to climate change. This study, therefore, applied a case-study approach to examine farmers' preference for climate change adaptation strategies and the factors deriving their preference. Thus, households' preference for five types of climate change adaptation strategies (multiple cropping, livestock, soil conservation, irrigation, and changing planting dates) is identified and the determinants of the preference are analyzed using Rank-Ordered Logit Model. The results indicated that multiple cropping is the most preferred and frequently applied adaptation strategy to climate change, while livestock production is the least. The model also revealed that gender, age, farming experience and education level of the household head, household size, and farm and nonfarm income; farm size and farm distance to homestead; agricultural extension services and access to climate forecast information; farmers' perceptions on temperature and rainfall affect farmers' preference for the climate change adaptation strategies. Thus, policies and programs with the aim of reducing climate change impacts through adaptation need to consider important roles of these factors. The main barriers to climate change adaptation are lack of information or knowledge, shortage of money, shortage of land, and unsuitability of land and poor potential for irrigation. Although adaptation is one of the policy options for reducing the negative impacts of climate change, it is challenged by these constraints. Therefore, promoting investments and strengthening efforts to address these constraints is suggested to enhance farmers' adaptation capacity and thus adaptation to climate change.

description: Let $X=\{X(t)\}_{t\geq0}$ be an operator semistable Lévy process on $\mathbb{R}^d$ with exponent $E$, where $E$ is an invertible linear operator on $\mathbb{R}^d$. In this paper we determine exact Hausdorff measure functions for the range of $X$ over the time interval $[0,1]$ under certain assumptions on the principal spectral component of $E$. As a byproduct we also present Tauberian results for semistable subordinators and sharp bounds for the asymptotic behavior of the expected sojourn times of $X$.

description: In-hand manipulation is challenging for a multi-finger robotic hand due to its high degrees of freedom and the complex interaction with the object. To enable in-hand manipulation, existing deep reinforcement learning based approaches mainly focus on training a single robot-structure-specific policy through the centralized learning mechanism, lacking adaptability to changes like robot malfunction. To solve this limitation, this work treats each finger as an individual agent and trains multiple agents to control their assigned fingers to complete the in-hand manipulation task cooperatively. We propose the Multi-Agent Global-Observation Critic and Local-Observation Actor (MAGCLA) method, where the critic can observe all agents' actions globally, and the actor only locally observes its neighbors' actions. Besides, conventional individual experience replay may cause unstable cooperation due to the asynchronous performance increment of each agent, which is critical for in-hand manipulation tasks. To solve this issue, we propose the Synchronized Hindsight Experience Replay (SHER) method to synchronize and efficiently reuse the replayed experience across all agents. The methods are evaluated in two in-hand manipulation tasks on the Shadow dexterous hand. The results show that SHER helps MAGCLA achieve comparable learning efficiency to a single policy, and the MAGCLA approach is more generalizable in different tasks. The trained policies have higher adaptability in the robot malfunction test compared to the baseline multi-agent and single-agent approaches.

description: We consider what happens when a many body localized system is coupled to a heat bath. Unlike previous works, we do not restrict ourselves to the limit where the bath is large and effectively Markovian, nor to the limit where back action on the bath is negligible. We identify limits where the effect of the bath can be captured by classical noise, and limits where it cannot. We also identify limits in which the bath delocalizes the system, as well as limits in which the system localizes the bath. Using general arguments and dimensional analysis, we constrain the overall phase diagram of the coupled system and bath. Our analysis incorporates all the previously discussed regimes, and also uncovers a new intrinsically quantum regime that has not hitherto been discussed. We discuss baths that are themselves near a localization transition, or are strongly disordered but protected against localization by symmetry or topology. We also discuss situations where the system and bath have different dimensionality (the case of `boundary MBL' and `boundary baths').

The Effect of Supply Chain Management Practice on Organizational Performance: the case of BGI Ethiopia
Creators: name: Haile, Mesele
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: One of the most significant changes in the paradigm of modern business management is that individual businesses no longer compete as solely autonomous entities, but rather as supply chains. In this emerging competitive environment, the ultimate success of the business will depend on management's ability to integrate the company's intricate network of business relationships. Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance since competition is no longer between organizations, but among supply chains. Supply chain management (SCM) is one of the most important tools that companies use to develop their performances. The basic objectives of this research was to study the relationship between supply chain management practices and organizational performance of BGI Ethiopia, four key dimensions of SCM practices (strategic supplier partnership, customer relationship, level of information sharing and quality of information sharing) were used as independent variables. A sample of 47 employees and 6 distribution agents taken. A questionnaire was used as a research tool for the collection of data. Baseline data was gotten from employees and agents of the company and also from secondary data. Collected data were analyzed through SPSS version 23. Main findings of the study revealed that there is a low level of practical implementation of SCM practices in BGI Ethiopia and that only Customer relationship has strong significant influence on competitive advantage. Strategic supplier partnership, Level of information sharing and Level of information quality on competitive advantage has no significant influences on competitive advantage of the case company. Quality, Delivery dependability and time to market have strong significant influences on organizational performance.

City planning

description: In the 1960s, planners from MIT and Harvard, supported by an interdisciplinary group, were invited by the Venezuelan government to interact with national professionals to create a "growth pole" in the southern part of the country. A city named Ciudad Guayana was founded in 1961. The planning process that followed was extensively documented by this group of American scholars and their counterparts in Venezuela. Probably the strongest critique to this process has been presented by the American anthropologist Lisa Peattie who, in Planning: Rethinking Ciudad Guayana (1987), unveils the unbridgeable gap between the "platonic city" designed by the planners based on the development paradigm, and the "aristotelian city" that unfolded in reality. This study investigates national and local politics in the planning, decision-making, and building practices of the city, and their definite imprint on its urban form and quality of life. Emphasis is placed on the last 15 years, and particularly the period since 1999, when Hugo Chávez Frías assumed the presidency of Venezuela.

description: We construct the Hermitian Schrödinger Hamiltonian of spin-less as well as the gauge-covariant Pauli Hamiltonian of spin one-half particles in a magnetic field that are confined to cylindrical and spherical surfaces. The approach does not require the use of involved differential-geometrical methods and is intuitive and physical, relying on the general requirements of Hermicity and gauge-covariance. The surfaces are embedded in the full three-dimensional space and confinement to the surfaces is achieved by strong radial potentials. We identify the Hermitian and gauge-covariant (in the presence of a magnetic field) physical radial momentum in each case and set it to zero upon confinement to the surfaces . The resulting surface Hamiltonians are seen to be automatically Hermitian and gauge-covariant. The well-known geometrical kinetic energy also emerges naturally.

description: The Kochen-Specker theorem states that exclusive and complete deterministic outcome assignments are impossible for certain sets of measurements, called Kochen-Specker (KS) sets. A straightforward consequence is that KS sets do not have joint probability distributions because no set of joint outcomes over such a distribution can be constructed. However, we show it is possible to construct a joint quasiprobability distribution over any KS set by relaxing the completeness assumption. Interestingly, completeness is still observable at the level of measurable marginal probability distributions. This suggests the observable completeness might not be a fundamental feature, but a secondary property.

description: This work proposes four novel hybrid quadrature schemes for the efficient and accurate evaluation of weakly singular boundary integrals (1/r kernel) on arbitrary smooth surfaces. Such integrals appear in boundary element analysis for several partial differential equations including the Stokes equation for viscous flow and the Helmholtz equation for acoustics. The proposed quadrature schemes apply a Duffy transform-based quadrature rule to surface elements containing the singularity and classical Gaussian quadrature to the remaining elements. Two of the four schemes additionally consider a special treatment for elements near to the singularity, where refined Gaussian quadrature and a new moment-fitting quadrature rule are used. The hybrid quadrature schemes are systematically studied on flat B-spline patches and on NURBS spheres considering two different sphere discretizations: An exact single-patch sphere with degenerate control points at the poles and an approximate discretization that consist of six patches with regular elements. The efficiency of the quadrature schemes is further demonstrated in boundary element analysis for Stokes flow, where steady problems with rotating and translating curved objects are investigated in convergence studies for both, mesh and quadrature refinement. Much higher convergence rates are observed for the proposed new schemes in comparison to classical schemes.
Selbstbestimmt trotz Vertretungsbeistandschaft? Eine qualitative Untersuchung der Wahrnehmung junger Erwachsener über ihre Autonomie in der zivilrechtlichen Betreuung
Creators: name: Tenner, Jenny
Publisher: name: Zenodo

description: In der Sozialen Arbeit ist das Recht auf Selbstbestimmung von zentraler Bedeutung und verlangt ethisch, dass alle Menschen das Recht haben, ihre eigenen Entscheidungen zu treffen. Diese Betonung gewinnt insbesondere im zivilrechtlichen Erwachsenenschutz, bei der Betreuung von Personen mit einem Schwächezustand und einem Schutzbedarf an Bedeutung, wo die Förderung und Ermöglichung der Selbstbestimmung als bedeutende rechtliche Leitlinie erachtet wird. In der Realisierung befinden sich Fachpersonen in einem komplexen Spannungsfeld zwischen dem Recht auf Selbstbestimmung und den eingeschränkten Fähigkeiten der Klientel zur Ausübung dieses Rechts. Die Forschungsarbeit legt Resultate dar, die aus der Perspektive junger Erwachsener von 18 bis 25 Jahren die Einschätzung ihrer Vertretungsbeistandschaft eruiert und deren Wahrnehmung eines selbstbestimmten Lebens beleuchtet. Dies ist in Anbetracht der Tatsache bedeutsam, da sich gerade in dieser Lebensphase die Entfaltung persönlicher und finanzieller Autonomie im Zentrum des individuellen Entwicklungsprozesses befindet, während gleichzeitig eine Vertretungsbeistandschaft dieses Streben einschränken kann. Die Ergebnisse verdeutlichen, dass die Lebensumstände der jungen Erwachsenen von grosser Komplexität geprägt sind und die Wahrnehmung ihrer Selbstbestimmung von verschiedenen Einflussfaktoren wie Gesundheit oder schwierigen Familienverhältnissen determiniert wird. Die Erkenntnisse unterstreichen einerseits den Unterstützungsbedarf und heben gleichzeitig die Notwendigkeit hervor, dass Berufsbeistandspersonen auf die spezifischen Bedürfnisse junger Menschen reagieren müssen, um in diesem Handlungsfeld bedarfsgerecht zu agieren.

The study is also conducted test for weak exogeneity and test for zero restrictions on co-integrating vectors to determine causality relationship and level of significance among equilibrium established variables. The result indicated that real GDP positively and strongly associated with physical capital, but negatively and significantly with budget deficit and political instabilities. The study could not find strong evidence which supports the existence of macro instability in the long-run other than short-run impact. The existence of war as indicator of political instability, adversely affects real GDP both in the long-run and short-run. In Ethiopia context, physical capital is found to be more important than human capital probably due to lesser human capital are accumulated in the stock.

description: Currently, radiobiology experiments using heavy ions at GANIL(Grand Accelerateur National d Ions Lourds) are conducted under the supervision of the CIMAP (Center for research on Ions, MAterials and Photonics). In this context, a new beam monitoring equipment named DOSION has been developed. It allows to perform measurements of accurate fluence and dose maps in near real time for each biological sample irradiated. In this paper, we present the detection system, its design, performances, calibration protocol and measurements performed during radiobiology experiments. This setup is currently available for any radiobiology experiments if one wishes to correlate one s own sample analysis to state of the art dosimetric references.

description: Machine learning (ML) enabled classification models are becoming increasingly popular for tackling the sheer volume and speed of online misinformation and other content that could be identified as harmful. In building these models, data scientists need to take a stance on the legitimacy, authoritativeness and objectivity of the sources of ``truth" used for model training and testing. This has political, ethical and epistemic implications which are rarely addressed in technical papers. Despite (and due to) their reported high accuracy and performance, ML-driven moderation systems have the potential to shape online public debate and create downstream negative impacts such as undue censorship and the reinforcing of false beliefs. Using collaborative ethnography and theoretical insights from social studies of science and expertise, we offer a critical analysis of the process of building ML models for (mis)information classification: we identify a series of algorithmic contingencies--key moments during model development that could lead to different future outcomes, uncertainty and harmful effects as these tools are deployed by social media platforms. We conclude by offering a tentative path toward reflexive and responsible development of ML tools for moderating misinformation and other harmful content online.

description: We study superdense coding with uniformly accelerated particle in single mode approximation and beyond single mode approximation. We use four different functions, the capacity of superdense coding, negativity, discord and the probability of success for evaluating the final results. In single mode approximation, all the four functions behave as expected, however in beyond single mode approximation, except the probability of success, the other three functions represent peculiar behaviors at least for special ranges where the beyond single mode approximation is strong.

Finite Temperature Considerations in the Structure of Quadratic GUP-modified White Dwarfs

description: In quantum gravity phenomenology, the effect of the generalized uncertainty principle (GUP) on white dwarfs has been given much attention in the literature. However, these studies assume a zero temperature equation of state (EoS), consequently excluding young white dwarfs whose initial temperatures are substantially high. To that cause, this paper calculates the Chandrasekhar EoS and resulting mass-radius relations of finite temperature white dwarfs modified by the quadratic GUP, an approach that extends Heisenberg's uncertainty principle by a quadratic term in momenta. The EoS was first approximated by treating the quadratic GUP parameter as perturbative, causing the EoS to exhibit expected thermal deviations at low pressures, and conflicting behaviors at high pressures, depending on the order of approximation. We then proceeded with a full numerical simulation of the modified EoS, and showed that in general, finite temperatures cause the EoS at low pressures to soften, while the quadratic GUP stiffens the EoS at high pressures. This modified EoS was then applied to the Tolman-Oppenheimer-Volkoff equations and its classical approximation to obtain the modified mass-radius relations for general relativistic and Newtonian white dwarfs. The relations for both cases were found to exhibit the expected thermal deviations at small masses, where low-mass white dwarfs are shifted to the high-mass regime at large radii, while high-mass white dwarfs acquire larger masses, beyond the Chandrasekhar limit. Additionally, we find that for sufficiently large values of the GUP parameter and temperature, we obtain mass-radius relations that are completely removed from the ideal case, as high-mass deviations due to GUP and low-mass deviations due to temperature are no longer mutually exclusive.

description: We have found experimentally that the rise times of voltage pulses in NbN superconducting single photon detectors increase nonlinearly with increasing detector length. We fabricated superconducting single photon detectors based on NbN thin films with a meander-like sensitive region of area from 2x2um2 to 11x11um2. The effect is connected with the dependence of the detector resistance, which appears after photon absorption, on its kinetic inductance and hence on detector length. This conclusion is confirmed by our calculations in the framework of the two-temperature model.

description: Recent progress in the development of quantum technologies has enabled the direct investigation of dynamics of increasingly complex quantum many-body systems. This motivates the study of the complexity of classical algorithms for this problem in order to benchmark quantum simulators and to delineate the regime of quantum advantage. Here we present classical algorithms for approximating the dynamics of local observables and nonlocal quantities such as the Loschmidt echo, where the evolution is governed by a local Hamiltonian. For short times, their computational cost scales polynomially with the system size and the inverse of the approximation error. In the case of local observables, the proposed algorithm has a better dependence on the approximation error than algorithms based on the Lieb-Robinson bound. Our results use cluster expansion techniques adapted to the dynamical setting, for which we give a novel proof of their convergence. This has important physical consequences besides our efficient algorithms. In particular, we establish a novel quantum speed limit, a bound on dynamical phase transitions, and a concentration bound for product states evolved for short times.
