The metal-insulator transition in Mn-substituted Sr₃Ru₂O₇ by a photoemission study
Creators: name: Zhu, Zhi Huai
Publisher: name: University of British Columbia
Year: 2009

description: We have studied the metal-insulator transition (MIT) in Mn-substituted Sr₃Ru₂O₇ by x-ray photoemission (XPS) and angle-resolved photoemission spectroscopy (ARPES). In XPS, both the surface- and bulk-sensitive spectra show a two-peak structure, corresponding to the well screened and the unscreened excitations. The evolution of the well screened peak with Mn is that the higher the concentration of Mn impurities, the lower the intensity of the peak, indicating that the screening channels are determined by the metallic property of a system. In ARPES, a strong doping dependence is also observed for the Fermi surface, which loses the 2D sheet associated with the dxy band and reduces to the 1D dxz/yz Fermi surfaces, as the system changes from metal to a Mott insulator. As for the band dispersion, we see that the dxy band shifts in energy toward the chemical potential, becoming degenerate with the dxz/yz bands, to the point of being indistinguishable. A nesting vector (0.33, 0.33, 0) has been determined from the Fermi surface of the 10% Mn doped sample, as in response to-or alternatively inducing-a charge/orbital ordering across the Mott transition. The opening of an energy gap is observed below the MIT both as a function of temperature and Mn substitution. To obtain a microscopic understanding of the MIT, we have performed a local-density approximation calculations for the electronic structures of Sr₃Ru₂O₇ and found that spin-orbital coupling induces an unexpected magnetic anisotropy. This might play a key role in the emergence of the MIT and magnetic superstructure in Mn-substituted Sr₃Ru₂O₇, as well as the nematic behavior in the parent compound.

description: The recently observed Seebeck spin tunneling, the thermoelectric analog of spin-polarized tunneling, is described. The fundamental origin is the spin dependence of the Seebeck coefficient of a tunnel junction with at least one ferromagnetic electrode. Seebeck spin tunneling creates a thermal flow of spin-angular momentum across a tunnel barrier without a charge tunnel current. In ferromagnet/insulator/semiconductor tunnel junctions this can be used to induce a spin accumulation (Δμ) in the semiconductor in response to a temperature difference (ΔT) between the electrodes. A phenomenological framework is presented to describe the thermal spin transport in terms of parameters that can be obtained from experiment or theory. Key ingredients are a spin-polarized thermoelectric tunnel conductance and a tunnel spin polarization with non-zero energy derivative, resulting in different Seebeck tunnel coefficients for majority and minority spin electrons. We evaluate the thermal spin current, the induced spin accumulation and Δμ/ΔT, discuss limiting regimes, and compare thermal and electrical flow of spin across a tunnel barrier. A salient feature is that the thermally-induced spin accumulation is maximal for smaller tunnel resistance, in contrast to the electrically-induced spin accumulation that suffers from the impedance mismatch between a ferromagnetic metal and a semiconductor. The thermally-induced spin accumulation produces an additional thermovoltage proportional to Δμ, which can significantly enhance the conventional charge thermopower. Owing to the Hanle effect, the thermopower can also be manipulated with a magnetic field, producing a Hanle magnetothermopower.

description: The Pomegranate is cultivated as a commercial crop because of its high income generating capacity. There are number of Private people working as consultants along with public extension personnel. The study was conducted in Hiriyuru, Hosdurga and Challakere taluk of Chitradurga district with a total sample size of 30 extension personnel, comprising of 17 public and 13 private extension personnel and 120 pomegranate growers, 60 each from public and private extension users. The study shows the communication pattern adopted by the public and private extension personnel to provide information to the pomegranate growers as well as the communication pattern preferred by the pomegranate growers to get the information from public and private agricultural extension systems. It is interesting to know that under individual contact method the cent per cent of the private Extension personnel used Farm and home visits and Telephone calls whereas, the public Extension personnel widely depend on Telephone calls (91.18%). under the group contact method of communication. Majority of the Public Extension Personnel resorted for Farmers Training (70.59%) whereas, Private Extension personnel relied more on Group discussion (84.62%). It is curious to know that in mass contact media, Majority of the Public Extension Personnel used Exhibition (61.76%) Whereas, Cent per cent of the Private Extension personnel dependent on Social Media. In case of demonstration method, both the public and private extension system used Method Demonstrations. Majority of the Public Extension personnel used Charts (64.71%) and majority of the Private Extension Personnel used Photographs (92.31%) as visual aid for extending information on pomegranate cultivation. In case of thecommunication pattern used by the pomegranate growers, Majority of the pomegranate growers who were availingservices from Public extension system used visual aids (66.11%) Whereas, the pomegranate growers who were with the private extension service obtained the information through visual aids (48.89%) followed by individual contact method (40.83%).

Subjects: subject: Algebraic Geometry (math.AG)

description: In this paper, we first show that homogeneous Keller maps are injective on lines through the origin. We subsequently formulate a generalization, which is that under some conditions, a polynomial endomorphism with $r$ homogeneous parts of positive degree does not have $r$ times the same image point on a line through the origin, in case its Jacobian determinant does not vanish anywhere on that line. As a consequence, a Keller map of degree $r$ does not take the same values on $r > 1$ collinear points, provided $r$ is a unit in the base field. Next, we show that for invertible maps $x + H$ of degree $d$, such that $\ker \jac H$ has $n-r$ independent vectors over the base field, in particular for invertible power linear maps $x + (Ax)^{*d}$ with $\rk A = r$, the degree of the inverse of $x + H$ is at most $d^r$.

description: Die verstärkte Nutzung von erneuerbaren Energien erfordert eine Flexibilisierung des elektrischen Energiesystems. In der Arbeit wird durch eine Kombination von linearer Optimierung und Systemsimulation untersucht, welche Maßnahmen die Netzstabilität und die Ausnutzung der erneuerbaren Energien verbessern können. Es zeigt sich, dass Energiespeicher, Verbrauchersteuerung und ein angepasster Einsatz von Anlagen in Kraft-Wärme-Kopplung dazu geeignet sind. Bei der Regelung und Steuerung müssen die Wechselwirkungen zwischen Erzeugereinsatz, teilweise gesteuertem Verbrauch und Wirkleistungs-Frequenz-Regelung berücksichtigt werden. Dies wird durch das entwickelte Simulationsverfahren ermöglicht.
description: Growing shares of intermittent renewable energy sources in power systems lead to temporal imbalances between supply and demand. In this thesis several measures to improve the power system stability and integration of renewable energies are investigated using a combination of linear optimization and system simulation. The results show that energy storages, demand response and flexible cogeneration concepts are suitable for this. Furthermore, the investigation of these measures requires a simulation approach that takes into account the interactions between the supply and demand as well as power system stability, which can be achieved by the developed simulation procedure.

description: Volume of moduli space of BPS vortices on a compact genus h Riemann surface Sigma_h is evaluated by means of topological field theory and localization technique. Vortex in Abelian gauge theory with a single charged scalar field (ANO vortex) is studied first and is found that the volume of the moduli space agrees with the previous results obtained more directly by integrating over the moduli space metric. Next we extend the evaluation to non-Abelian gauge groups and multi-flavors of scalar fields in the fundamental representation. We find that the result of localization can be consistently understood in terms of moduli matrix formalism wherever possible. More details are found in our paper in Prog.Theor.Phys.126 (2011) 637.

description: In Chapter One I will outline how it is possible to construct reality in accordance with our ideas. The notion of fundamental constitutive rules will be seen to be central to this construction and the bulk of that chapter will be devoted to examining what such rules are and what they involve. They will be seen to involve a specific group of persons for each such rule or set of rules. That is, each such rule or set of rules is a rule or set of rules for, but not necessarily only for, a specifically delineated group of human beings. In the following chapters I will be concerned with demonstrating the scope of the notion of fundamental constitutive rules. Chapter Two concerns the limits of the notion and hence the limits of the notion of constructing reality. Chapter Three concerns the effects of the notion of fundamental constitutive rules on five conceptually related notions: alternate realities, conceptual systems, understanding, assessment and persons. In Chapter Four I will return to the fact that the notion of fundamental constitutive rules inescapably involves a specifically delineated group of persons and will attempt to demonstrate what this means both for those within and those without the delineated group. This demonstration will bring to light the fact that the notion of alternate realities is the key notion in this essay. In Chapter Five I will attempt to show that this notion is coherent by examining both the laws of thought and the notion of necessity.

description: The Josephson energy of two superconducting islands containing Majorana fermions is a 4π-periodic function of the superconducting phase difference. If the islands have a small capacitance, their ground state energy is governed by the competition of Josephson and charging energies. We calculate this ground state energy in a ring geometry, as a function of the flux -Φ- enclosed by the ring, and show that the dependence on the Aharonov-Bohm phase 2eΦ/\hbar remains 4π-periodic regardless of the ratio of charging and Josephson energies - provided that the entire ring is in a topologically nontrivial state. If part of the ring is topologically trivial, then the charging energy induces quantum phase slips that restore the usual 2π-periodicity.

description: The purpose of this paper is twofold: from one side we provide a general survey to the viscoelastic models constructed via fractional calculus and from the other side we intend to analyze the basic fractional models as far as their creep, relaxation and viscosity properties are considered. The basic models are those that generalize via derivatives of fractional order the classical mechanical models characterized by two, three and four parameters, that we refer to as Kelvin-Voigt, Maxwell, Zener, anti-Zener and Burgers. For each fractional model we provide plots of the creep compliance, relaxation modulus and effective viscosity in non dimensional form in terms of a suitable time scale for different values of the order of fractional derivative. We also discuss the role of the order of fractional derivative in modifying the properties of the classical models.

Methoden für den Einsatz periodischer Strukturen zur Strahlteilung und -summierung im Submillimeterwellenbereich werden verglichen. Zum einen gibt es Fernfeldmethoden, die ihren Ursprung im Dammann-Gitter haben, zum anderen Nahfeldmethoden - wie die näher untersuchte holographische Leistungsaddition mit periodischen Strukturen -, welche auf dem Talbot-Effekt basieren. Der Wirkungsgrad wird mit einem exakten Modell aus verallgemeinerten Streuparametern und Eigenwellen-Entwicklung erforscht. Die resultierende räumlich begrenze, ebene Welle wird mit einer geeigneten Auskoppelschaltung in einen Gaussstrahl umgewandelt, indem die Phase durch spezielle Linsen oder Spiegel beeinflusst wird. Eine näherungsweise Bestimmung der Obeflächenkonturen erfolgt mit strahlenoptischer Zuordnung per Leistungsverteilungsfunktion. Für die Optimierung wird die lokale Strahlenoptik eingeführt. Die Justage und Bewertung der realisierten Aufbauten bei 150 GHz erfolgt u. a. mit einem vektoriellen Feldmesssystem und breitbandigen Leistungsteiler.
description: This thesis investigates multi-element circuit technologies for quasi-optical power combining. For this purpose, methods for the application of periodic structures for splitting and summarization of rays in the submillimeter wave range are compared. On the one hand, there are far field methods, which have their origin in the Dammann grating. On the other hand, there are near field methods - like the analysed holographic power combining with periodic structures - which are based on the Talbot effect. The power combining efficiency is examined via a rigorous model which consists of generalized scattering matrixes and eigenmode development. The resulting pseudo plane wave is transformed into a Gaussian beam with an adequate quasi-optical circuit. This is performed by modification of the phase distribution with specially designed lenses and mirrors. An approximated determination of the surface contours is performed by geometrical optics with power distribution mapping. For their optimisation the local geometrical optics is introduced. The adjustment and validation of the realized set-ups at 150 GHz is performed by a vectorial field measurement system and a broadband power divider.

description: In capillary electrophoresis, sample ions migrate along a micro-capillary filled with a background electrolyte under the influence of an applied electric field. If the sample concentration is sufficiently high, the electrical conductivity in the sample zone could differ significantly from the background.Under such conditions, the local migration velocity of sample ions becomes concentration dependent resulting in a nonlinear wave that exhibits shock like features. If the nonlinearity is weak, the sample concentration profile, under certain simplifying assumptions, can be shown to obey Burgers' equation (S. Ghosal and Z. Chen Bull. Math. Biol. 2010, 72(8), pg. 2047) which has an exact analytical solution for arbitrary initial condition.In this paper, we use a numerical method to study the problem in the more general case where the sample concentration is not small in comparison to the concentration of background ions. In the case of low concentrations, the numerical results agree with the weakly nonlinear theory presented earlier, but at high concentrations, the wave evolves in a way that is qualitatively different.

“That’s a cause I believe in”: a qualitative investigation of donors’ and practitioners’ understanding of people’s reasons for giving

Subjects: subject: Sociology
subject: FOS: Sociology
subject: Social and personality psychology

description: Critics of modern charitable giving allege that much of this activity fails to produce any positive impact for the beneficiaries of this aid or in making progress towards enacting whatever form of change these causes are trying to address. One reason that has been proposed for this purported failure is that individual donors choose to give according to their personal preferences and tastes rather than donate to organisations that produce the most positive effect from their work. In response to these allegations, some approaches to donating have emerged that focus on applying a more rational approach to how people give and generate the most possible good from this act. Much of the extant literature explaining why donors give explores specific antecedents that drive them to do this. However, broader explorations of why people may give based on personal tastes and preferences are scant. Additionally, prior research exploring donors’ considerations for the efficacy and impact of their giving presents contrasting results. This work commonly advances the viewpoint that donors say they want their giving to have an impact and positive effect but that they make no effort to assess whether it does. This thesis investigates how members of the donating public perceive of their reasons for giving to charity, along with their considerations for the ultimate effect of this activity. The findings draw on qualitative data from forty interviews with individual donors, and charity fundraisers and managers to produce a holistic interpretation of these concepts. Key learnings from this work were that donors’ giving was motivated by autobiographical factors driving this, and that although they did not actively engage with the results of their donating, they evaluated effectiveness in other ways that were pertinent to them. A third emergent topic was also identified, which revealed how trust mediated their considerations for the results and effectiveness of their charitable giving. In contrast to the aforementioned criticism of modern charity, this work proposes that donors’ personal reasons for giving and the ways in which they consider charity effectiveness are not incompatible concepts. Understanding why donors give and how they perceive of charity effectiveness is key to assisting them in making more informed choices about the charities they give to. The findings of this work build on the learnings from studies investigating the public’s donating motivations, concerns for efficacy and impact, and regard for charitable trust. They are likely to be of interest to those working in or researching the wider charity sector.

description: We present searches for rare or forbidden charm decays of the form $X_c^+\to h^\pm\ell^\mp\ell^{(\prime)+}$, where $X_c^+$ is a charm hadron ($D^+$, $D^+_s$, or $Λ_c^+$), $h^\pm$ is a pion, kaon, or proton, and $\ell^{(\prime)\pm}$ is an electron or muon. The analysis is based on $384 fb^{-1}$ of $e^+e^-$ annihilation data collected at or close to the $Υ(4S)$ resonance with the BaBar detector at the SLAC National Accelerator Laboratory. No significant signal is observed for any of the 35 decay modes that are investigated. We establish 90% confidence-level upper limits on the branching fractions between $1 \times 10^{-6}$ and $44 \times 10^{-6}$ depending on the channel. In most cases, these results represent either the first limits or significant improvements on existing limits for the decay modes studied.

description: I argue that, despite repeated claims of Ibata et al., the globular cluster NGC 2419 does not pose a problem for modified Newtonian dynamics (MOND). I present a new polytropic model with a running polytropic index. This model provides an improved representation of the radial distribution of surface brightness while maintaining a reasonable fit to the velocity dispersion profile. Although it may be argued that the differences with these observations remain large compared to the reported random errors, there are several undetectable systematic effects which render a formal likelihood analysis irrelevant. I comment generally upon these effects and upon the intrinsic limitations of pressure supported objects as tests of gravity.

description: Promoting social information reporting and disclosure can promote sustainable banking. The paper aims to measure banking social sustainability by constructing a new interval-based composite indicator using the Thomson Reuters database. In this work, we propose an approach to constructing interval-based composite indicators that enhance the composite indicator’s construction sensibly, allowing us to measure the uncertainty due to the choices in the composite indicator design. The methodological approach employed is based on a Monte-Carlo simulation and allows for improving the information the composite indicators can obtain. So, we measure the value of the social indicator and its subcomponents and the value’s uncertainty due to the different possible weights. The results show that the best international ESG practices in European banks relate to French and United Kingdom Banks, primarily than Italian banks. Finally, we analyze innovative perspectives and propose policy recommendations, considering the growing attention to the issue of ESG disclosure and its adherence to reality, to support sustainable banking ecosystems.

Development and testing of a 2D axisymmetric water flow and solute transport model for heap leaching
Creators: name: Afewu, Kodjo Isaac

Year: 2009

description: Heap leaching is an industrially relevant process for extracting metal values from marginal ores and/or pretreating ores for subsequent extraction of valuable metals. Its advantages include low capital and operating costs, rapid construction times, and relatively low environmental impact. The movement of water and solutes through a heap of ore has serious implications for efficiency of heap leach operations. Solutes (whether introduced into or generated within a heap) move with the water and tend to mix with the bulk solution by the mechanisms of advection and dispersion. Though it is well known that ore-water characteristics influence water flow and solute transport properties during heap leaching, these properties have not been adequately incorporated into the design and operation strategies of heap leaching. In this work, a mathematical model and the results of special laboratory experiments are used to study the reaction and/or transport of solutes during heap leaching. The model is 2D axisymmetric, comprising transport of solutes by advection and dispersion in a bed of broken ore under a point source of solution representing a single drip emitter. The ore hydraulic parameters characterize the water retention and permeability properties, while the transport and chemical parameters affect the distribution of water and solutes, and the rates and extents of reactions of solutes in the heap. The close agreement between the observed data and the predicted results lends credence to the modeling approach and its solution methodology. It was observed that, within the limited water content range relevant to safe and successful operation of a heap leach facility, dispersivity increased with increasing irrigation flux and hence water content. The model captured the trends in water and lixiviant distribution, and solute transport in heaps, clearly demonstrating the importance of incorporating ore hydraulic parameters in modeling heap leaching. It was also found that transport of solutes is slower than leaching and hence the former is the rate limiting step in the process. The model can be used to simulate various process enhancement strategies for efficient operation and optimal design, as well as economic evaluations and potential environmental impact assessment of heap leaching operations.

description: We investigate the relaxation process and the dynamical heterogeneities of the kinetically constrained Kob--Anderson lattice glass model, and show that these are characterized by different timescales. The dynamics is well described within the diffusing defect paradigm, which suggest to relate the relaxation process to a reverse--percolation transition. This allows for a geometrical interpretation of the relaxation process, and of the different timescales.
Workshop "Hamburger Innovationsaudit" - Erwartungen und Ziele
Creators: name: Herstatt, Cornelius

name: Trapp, Stefan
Publisher: name: TUHH Universitätsbibliothek
Year: 2007

description: Gründe für die Initiierung des Workshops Schon zu Beginn des RIS-Hamburg-Projektes1 im Frühjahr 2006 wurde in Gesprächen mit Vertretern der Hamburger Behörde für Wirtschaft und Arbeit (BWA), der Innovationsstiftung Hamburg sowie des Innovations- und Patent-Centrums (IPC) der Handelskammer Hamburg die Idee eines „Hamburger Innovationsaudits“ thematisiert. Das TIM griff diese Überlegungen im Rahmen seiner Aktivitäten zum RIS-Hamburg-Projekt auf. Es initiierte eine Studie zur Stärken und Schwächenanalyse bestehender Innovationsaudits mit dem Ziel, die Leistungsmerkmale eines KMU-gerechten Innovationsaudits herauszuarbeiten. Das TIM versteht die Studie2 als einen Beitrag zur Erarbeitung eines „Hamburger Innovationsaudits“. In weiteren Gesprächen mit Vertretern der eingangs erwähnten Institutionen stellte sich später heraus, dass die diesbezüglichen Zielvorstellungen der involvierten Stellen zum Teil divergieren. Da auch noch weitere Hamburger Institutionen wie z.B. die Handwerkskammer oder Clustermanager sowie Verbandsvertreter der im Rahmen des RIS-Projektes untersuchten Branchen in die Konzeption eines „Hamburger Innovationsaudits“ eingebunden werden sollen, entstand die Idee der Initiierung eines Workshops.

The spectroscopic evolution of the recurrent nova T Pyxidis during its 2011 outburst I. The optically thick phase and the origin of moving lines in novae

description: The nova T Pyx was observed with high resolution spectroscopy (R ~ 65000) spectroscopy, beginning 1 day after discovery of the outburst and continuing through the last visibility of the star at the end of May 2011. The interstellar absorption lines of Na I, Ca II, CH, CH$^+$, and archival H I 21 cm emission line observations have been used to determine a kinematic distance. Interstellar diffuse absorption features have been used to determine the extinction independent of previous assumptions. Sample Fe-peak line profiles show the optical depth and radial velocity evolution of the discrete components. We propose a distance to T Pyx $\geq$4.5kpc, with a strict lower limit of 3.5 kpc (the previously accepted distance). We derive an extinction, E(B-V)$\approx0.5\pm$0.1, that is higher than previous estimates. The first observation, Apr. 15, displayed He I, He II, C III, and N III emission lines and a maximum velocity on P Cyg profiles of the Balmer and He I lines of $\approx$2500 km s$^{-1}$ characteristic of the fireball stage. These ions were undetectable in the second spectrum, Apr. 23, and we use the recombination time to estimate the mass of the ejecta, $10^{-5}f$M$_\odot$ for a filling factor $f$. Numerous absorption line systems were detected on the Balmer, Fe-peak, Ca II, and Na I lines, mirrored in broader emission line components, that showed an "accelerated" displacement in velocity. We also show that the time sequence of these absorptions, which are common to all lines and arise only in the ejecta, can be described by recombination front moving outward in the expanding gas without either a stellar wind or circumstellar collisions.

description: Gas-filled Time Projection Chambers (TPCs) with Gas Electron Multipliers (GEMs) and pixels appear suitable for direction-sensitive WIMP dark matter searches. We present the background and motivation for our work on this technology, past and ongoing prototype work, and a development path towards an affordable, 1-$\rm m^3$-scale directional dark matter detector, \dcube. Such a detector may be particularly suitable for low-mass WIMP searches, and perhaps sufficiently sensitive to clearly determine whether the signals seen by DAMA, CoGeNT, and CRESST-II are due to low-mass WIMPs or background.

Electrical measurement of spin-dependent resistivity in GaAs/AlGaAs two-dimensional electron gas

Year: 2009

description: The electrical transport in the semiconductor two-dimensional electron gases (2DEGs) in the presence of magnetic fields have been the subject of extensive experimental and theoretical studies. Whereas the experiments generally focus on the total magnetotransport of the spin-up and spin-down electrons, the problem of how individual spin components contribute to the sum has been mostly remained untouched. Due to the Zeeman splitting of the Fermi velocities, spin-up and spin-down electrons face different resistivities against their flow. In this thesis, this problem is addressed based on electrical generation and detection of nonequilibrium spin polarization in a narrow conducting channel of 2DEG in a GaAs/AlGaAs heterostructure. It makes use of narrow quasi-one-dimensional constrictions, known as quantum point contacts (QPCs), at a high magnetic field as the injector and detector of the spin polarization. We also simulate the problem based on an one-dimensional spin diffusion model and it turns out that it numerically agrees with the measurements using an electron spin susceptibility which is enhanced compared to that of bare GaAs. Such enhancements are generally linked with the electron-electron interactions which become important for electrons in confined geometries. The first section reviews the general characteristic properties of 2DEGs in GaAs/AlGaAs semiconductor heterostructures, gate-defined structures and quantized electrical transport through QPCs. The second chapter reviews the main results of electronic transport measurements on 2DEGs in the presence of in-plane magnetic fields, and the third chapter includes our spin polarization measurement results in a narrow channel of 2DEG and how they help to account for the effect of spin orientation on the electrical resistivity.

Publisher: name: TUHH Universitätsbibliothek
Year: 2005
Subjects: classificationCode: 004
subject: Informatik
subject: Dokumentenverwaltungssystem

description: Viele Hochschulen (bzw. die Hochschulbibliotheken) setzen heutzutage Dokumentenserver ein, um Dokumente online verfügbar zu machen und diese Online-Dokumente zu verwalten. In manchen Hochschulen ist es für die Studierenden sogar möglich, ihre Abschlussarbeit auf diesem Server zu veröffentlichen, was im Sinne der Promotionsordnung als ordnungsgemässe Veröffentlichung akzeptiert werden und so den Doktoranden eventuell hohe Kosten einer Verlagsveröffentlichung oder anderweitigen gedruckten Publikation ersparen kann. Ein solcher Dokumentenserver, der unter anderem in der Bibliothek der Technischen Universität Hamburg eingesetzt wird, ist OPUS. Um die Akzeptanz eines solchen Servers bei den Promovenden (aber auch den Studierenden, da OPUS nicht ausschliesslich Dissertationen und Habilitationen aufnimmt) zu erhöhen und sicherzustellen, dass der Server internationalen Standards folgt und so zum Beispiel auch von anderen Hochschulen oder Metasuchmaschinen etc. durchsucht werden kann, gibt es die Möglichkeit, einen Dokumentenserver zertifizieren zu lassen. Ein solches Zertifikat wird von der DINI (Deutsche Initiative für Netzwerkinformation) vergeben. In der vorliegenden Arbeit wird untersucht, inwiefern die Installation des Dokumentenservers OPUS an der TU Hamburg-Harburg die Zertifizierungsbedingungen der DINI erfüllt und wo ggf. Erweiterungsbedarf besteht.
