description: Neue gesetzliche und technische Rahmenbedingungen werden zu wesentlichen strukturellen Änderungen in der Energieversorgung führen. Bedingt durch die Altersstruktur des existierenden Kraftwerkparks besteht alleine in Deutschland in den nächsten zwei Dekaden ein wesentlicher Ersatzbedarf. Eine mögliche Option stellt in diesem Zusammenhang die verstärkte Integration kleiner, dezentraler Energieumwandlungsanlagen dar. Dabei hängt der Erfolg im Wesentlichen davon ab, ob es gelingt diese Anlagen in die bestehenden Netze und den Netzbetrieb einzubinden. Dies setzt die Möglichkeit zum Fernzugriff voraus. Als besondere Herausforderungen erweisen sich dabei die große räumliche Verteilung, die hohe Anlagenanzahl sowie die Vielzahl unterschiedlicher Anlagentypen. Unter diesen Gesichtspunkten werden zunächst allgemeine Anforderungen an mögliche Informationssysteme formuliert und heute am Markt befindliche Übertragungstechnologien auf ihre Einsetzbarkeit untersucht. Darauf aufbauend wird das Konzept eines verteilten hierarchischen Energiemanagement entwickelt und eine Möglichkeit zur praktischen Umsetzung auf Basis eines verteilten Datenbanksystems vorgestellt.
Appraisal of woreda-level fiscal decentralization in Addis Ababa city government: with particular reference to selected woredas
Creators: name: Ansaw, Eyob
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Fiscal decentralization is seen as part of a reform agenda in developing countries to strengthen regional and local governments. It is believed that it improves the efficiency of public service delivery through preference matching and allocation efficiency. In light of this, this study was conducted to assess the practices of Woreda level fiscal decentralization in Addis Ababa City Government. In doing this study, explanatory mixed method research design was followed. Subjects of the study were government officials working in selected Woredas and sub-cities of Addis Ababa city. In the study, multi-stage sampling technique was used to select representative respondents. To this effect, one hundred ninety-two participants were selected using multi-stage sampling technique. Besides, sub-city and Woreda Finance and Economic Development Bureaus officials were purposely selected to conduct key informant interviews. The data gathering instruments were questionnaire, key informant interviews, and document analysis. The study followed statistical tests to test the research hypotheses. It applied Kruskal Wallis test of significance. The study involved strict respect for informed consent, voluntary participation, and confidentiality. The findings of the statistics tests indicates that respondents' responses concerning autonomy of Woredas in planning and budgeting, revenue generation and retention, expenditure assignments were significantly different. This implies that there is absence of uniformity in the practices of these aspects of fiscal decentralization in the city. On the contrary, the respondents' response concerning the functionalities of institutional and legal frameworks, inter-governmental fiscal relations, challenges, and constraints of fiscal decentralization, were not significantly different. In general, the practice of fiscal decentralization in the city was limited as existing institutional and legal frameworks were in short of clarity and uniformity. Respondents stated that Woreda administrations had weak revenue base, and need clear planning and budgeting, and expenditure assignment autonomy. Based on the findings of the study, the research hence recommended that existing institutional and legal frameworks should be structured in the way that it enables Woreda administrations to generate and utilize sufficient revenues, plan and budget their own activities, have clear autonomy of expenditure assignments. Inter-governmental fiscal relations should also be planned to reduce the vertical imbalances observed at Woreda Administration level.

description: The irritative effects of preservatives found in ophthalmologic solution, or of antiseptics used for skin disinfection is a consistent problem for the patients. The reduction of the toxic effects of these compounds is desired. Brilliant Blue G (BBG) has shown to meet the expected effect in presence of benzalkonium chloride (BAK), a well known preservative in ophthalmic solutions, and octenidine dihydrochloride (Oct), used as antiseptic in skin and wound disinfection. BBG shows a significant protective effect on human corneal epithelial (HCE) cells against BAK and Oct toxicity, increasing the cell survival up to 51 % at the highest BAK or Oct concentration tested, which is 0.01 %, both at 30 min incubation. Although BBG is described as a P2x7 receptor antagonist, other selective P2x7 receptor antagonists, OxATP (adenosine 5’-triphosphate-2’,3’-dialdehyde) and DPPH (N’-(3,5-dichloropyridin-4-yl)-3-phenylpropanehydrazide), did not reduce the cytotoxicity of neither BAK nor Oct. Therefore we assume that the protective effect of BBG is not due to its action on the P2x7 receptor. Brilliant Blue R (BBR), a dye similar to BBG, was also tested for protective effect on BAK and Oct toxicity. In presence of BAK no significant protective effect was observed. Instead, with Oct a comparable protective effect was seen with that of BBG. To assure that the bacteriostatic effect is not affected by the combinations of BAK/BBG, Oct/BBG and Oct/BBR, bacterial growth inhibition was analyzed on different Gram-negative and Gram-positive bacteria. All combinations of BAK or Oct with BBG hinder growth of Gram-positive bacteria. The combinations of 0.001 % Oct and BBR above 0.025 % do not hinder the growth of B. subtilis. For Gram-negative bacteria, BBG and BBR reduce, but do not abolish, the antimicrobial effect of BAK nor of Oct. In conclusion, the addition of BBG at bacterial inhibitory concentrations is suggested in the ready-to-use ophthalmic preparations and antiseptic solutions.

Public Procurement Reforms in Ethiopia: Policy and Institutional Challenges and Prospects
Creators: name: Tesfahun, Yirga
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This study assessed key public procurement challenges in the Federal Government's public sectors and presents recent empirical evidences. The thesis begins by elaborating the background of the Ethiopian public procurement with regard to its historical genesis in the past three regimes. In addition, the study raised important questions about the legal and institutional frameworks that govern the procurement system of the Federal Government. Also questions about the integrity and transparency of the procurement operations and practices have been raised. The major objective of this study is to assess the FGE's public procurement system. In order to do so, the researcher has identified four thematic areas on which public procurement is assessed. These are legal and regulatory frameworks; institutional frameworks; public procurement operations and practices; and procurement integrity and transparency. These are the most widely recognized benchmarks against which public procurement is assessed by the World Bank and OECD. Methodologically this study is designed as descriptive. Unstructured interviews have been conducted with different stakeholders. In addition different secondary data i.e. legislations, reports, website publications, and researches from the PPA and other concerned public organizations have been collected. Data have been analyzed thematically on the aforementioned benchmarks. The results of this study show that a significant achievement has been made in reforming the Federal Government's procurement system. A new legal framework, which is based on universal standards, has been drafted. Also, secondary legislations have been issued. The institution responsible for the oversight of the public procurement system, however, has many setbacks in front of it. In addition, the research shows that insuring transparency and accountability is still at the middle of a road. Recommendations in the study are suggested including strengthening the capacity of the Public Procurement Agency's workforce, making the legislation more comprehensive; work with different stakeholders like the civil society organizations and the media on insuring transparency and combating corruption

description: Tensors have become prevalent in business applications and scientific studies. It is of great interest to analyze and understand the heterogeneity in tensor-variate observations. We propose a novel tensor low-rank mixture model (TLMM) to conduct efficient estimation and clustering on tensors. The model combines the Tucker low-rank structure in mean contrasts and the separable covariance structure to achieve parsimonious and interpretable modeling. To implement efficient computation under this model, we develop a low-rank enhanced expectation-maximization (LEEM) algorithm. The pseudo E-step and the pseudo M-step are carefully designed to incorporate variable selection and efficient parameter estimation. Numerical results in extensive experiments demonstrate the encouraging performance of the proposed method compared to popular vector and tensor methods. Supplementary materials are available online.

Skeletons of stable maps II: Superabundant geometries

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: We implement new techniques involving Artin fans to study the realizability of tropical stable maps in superabundant combinatorial types. Our approach is to understand the skeleton of a fundamental object in logarithmic Gromov--Witten theory -- the stack of prestable maps to the Artin fan. This is used to examine the structure of the locus of realizable tropical curves and derive 3 principal consequences. First, we prove a realizability theorem for limits of families of tropical stable maps. Second, we extend the sufficiency of Speyer's well-spacedness condition to the case of curves with good reduction. Finally, we demonstrate the existence of liftable genus 1 superabundant tropical curves that violate the well-spacedness condition.

description: We demonstrate an isomorphism between the homology of the strand algebra of bordered Floer homology, and the category algebra of the contact category introduced by Honda. This isomorphism provides a direct correspondence between various notions of Floer homology and arc diagrams, on the one hand, and contact geometry and topology on the other. In particular, arc diagrams correspond to quadrangulated surfaces, idempotents correspond to certain basic dividing sets, strand diagrams correspond to contact structures, and multiplication of strand diagrams corresponds to stacking of contact structures. The contact structures considered are cubulated, and the cubes are shown to behave equivalently to local fragments of strand diagrams.

description: Im Bereich der Echtzeitsysteme rücken Mehrkern-Prozessoren zunehmend in den Fokus. Dabei stellen Echtzeitsysteme besondere Anforderungen an die eingesetzte Systemarchitektur. Neben der logischen Korrektheit, ist in Echtzeitsystemen eine zeitlich vorhersagbare Ausführung entscheidend. Cache- Speicher spielen in dieser Hinsicht eine besondere Rolle. Zum einen sind sie notwendig, um schnelle Zugriffe auf Instruktionen und Daten zu gewährleisten, zum anderen beeinträchtigen sie die zeitliche Vorhersagbarkeit der Ausführung. Beim Zugriff auf gemeinsame Daten in Mehrkern-Prozessoren ist zudem der Einsatz eines Cache-Kohärenzverfahrens notwendig. Gängige Kohärenzverfahren können die Anforderungen an Performanz und Echtzeitfähigkeit nicht hinreichend erfüllen. Die in hardwarebasierten Kohärenzverfahren eingesetzten Kohärenzoperationen machen eine präzise WCET-Abschätzung undurchführbar. Der On-Demand Coherent Cache (ODC2) stellt ein Cache- Kohärenzverfahren dar, das im Hinblick auf den Einsatz in Echtzeitsystemen entwickelt wurde. Es verzichtet auf eine gegenseitige Beeinflussung von Cache- Speicher durch Kohärenzoperationen und erreicht dadurch eine hinreichende zeitliche Vorhersagbarkeit der Zugriffe auf gemeinsame Daten. Das Verfahren des ODC2 zielt auf eine möglichst effiziente Nutzung des Cache-Speichers hin. Im Vergleich zu gängigen, softwarebasierten Verfahren ermöglicht es eine signifikant höhere (Worst-Case) Performanz.

description: Vor dem Hintergrund der sich verändernden Anforderungen an die Produktion (zunehmende Flexibilität, höhere Produktivität etc.) wird die Frage gestellt, über welche Wege Orientierungen für betriebliche Innovationsprozesse vermittelt werden können. In diesem Zusammenhang wird die Frage untersucht, inwieweit das regionale Umfeld des Betriebs als unterstützender und orientierender Rahmen für solche Prozesse dienen kann. Durch Betriebsbefragungen, die das Institut Arbeit und Technik durchführte, wurde ermittelt, daß das regionale Umfeld gerade diese Funktion erfüllen kann. Gleichzeitig zeigen aber die Ergebnisse einer repräsentativen Befragung der nordrhein-westfälischen Betriebe, daß die Nutzung der aufgebauten Beratungs- und Transferinfrastruktur gegenüber konventionellen Informationsquellen eher gering ausgeprägt ist. Anhand von Erfahrungen aus Projekten, die sich gerade auf die Kooperation von betrieblichen und regionalen Akteuren richteten, werden die Chancen und Restriktionen einer Mobilisierung dieser Infrastruktur für die genannten Ziele herausgearbeitet.

Challenges in urban infrastructure service provision: The case of water, power and road sub sector in Hossana town, SNNPRS
Creators: name: Assefa, Lombeso
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study is aimed at examining the urban infrastructure challenges and prospects of water, power and road sub sectors in Hossana town of Hadiyya Zone, SNNPRS. It was based on cross section data collected from 212 randomly selected households from 5 kebeles in the town. The information obtained was further reinforced by focus group discussion and supporting secondary sources from the institutions. The data collected was processed using SPSS version 21. The findings indicate that the three subsectors infrastructure provided so far has been far from adequacy. The water subsector was rated more progressive, although nearly 50% of the respondent households have had no household level access. It was seen that 95% of the respondents have access for road of different quality. Compared to the other two sub sectors, the road subsector was found very much lagging, when rated for standard asphalt and cobble type road. Though 87% of the respondents have the access for power in one or another way, the capacity of the supplied power was found inadequate for utility with frequent power cuts. Moreover, the level of coordination among the sectors was found weak and the effort to ensure community participation in providing infrastructure was found limited. Major challenges identified include lack of infrastructure finance, limited technical capacity, shortage of adequate sources of supply, topographic challenges, fairness, transparency and accountability problems limitation on following the master plan of the town, uncontrolled expansion of the town size and increased demand for infrastructure due to increased complexity of the economic and social services in the town. The prospects analysis indicates that the water subsector would remain to be more challenging in the near future. The power subsector was under expansion but was found very sluggish in the process. The road sector was found dependent on external financial sources and need to mobilize infrastructure finance through community participation, improved transparency and accountability.

Revisiting radiative decays of $1^{+-}$ heavy quarkonia in the covariant light-front approach

description: We revisit the calculation of the width for the radiative decay of a $1^{+-}$ heavy $Q \bar Q$ meson via the channel $1^{+-} \to 0^{-+} +γ$ in the covariant light-front quark model. We carry out the reduction of the light-front amplitude in the non-relativistic limit, explicitly computing the leading and next-to-leading order relativistic corrections. This shows the consistency of the light-front approach with the non-relativistic formula for this electric dipole transition. Furthermore, the theoretical uncertainty in the predicted width is studied as a function of the inputs for the heavy quark mass and wavefunction structure parameter. We analyze the specific decays $h_{c}(1P) \to η_{c}(1S) + γ$ and $h_{b}(1P) \to η_{b}(1S) + γ$. We compare our results with experimental data and with other theoretical predictions from calculations based on non-relativistic models and their extensions to include relativistic effects, finding reasonable agreement.

Search for new resonances in events with one lepton and missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for $W^\prime$ bosons in events with one lepton (electron or muon) and missing transverse momentum is presented. The search uses 3.2 fb$^{-1}$ of $pp$ collision data collected at $\sqrt{s} = 13$ TeV by the ATLAS experiment at the LHC in 2015. The transverse mass distribution is examined and no significant excess of events above the level expected from Standard Model processes is observed. Upper limits on the $W^\prime$ boson cross-section times branching ratio to leptons are set as a function of the $W^\prime$ mass. Assuming a $W^\prime$ boson as predicted by the Sequential Standard Model, $W^\prime$ masses below 4.07 TeV are excluded at the 95% confidence level. This extends the limit set using LHC data at $\sqrt{s}=8$ TeV by around 800 GeV.

description: Modified Gravity (MOG) and Non-Local Gravity (NLG) are two alternative theories to General Relativity. They are able to explain the rotation curves of spiral galaxies and clusters of galaxies without including dark matter (Moffat & Rahvar 2013, 2014; Rahvar & Mashhoon 2014). In the weak-field approximation these two theories have similar forms, with an effective gravitational potential that has two components: (i) Newtonian gravity with the gravitational constant enhanced by a factor $(1+α)$ and (ii) a Yukawa type potential that produces a repulsive force with length scale $1/μ$. In this work we compare the rotation curves of dwarf galaxies in the LITTLE THINGS catalog with predictions of MOG, NLG and Modified Newtonian Dynamics (MOND). We find that the universal parameters of these theories, can fit the rotation curve of dwarf galaxies with a larger stellar mass to the light ratio compared to the nearby stars in the Milky Way galaxy. Future direct observations of mass function of stars in the dwarf galaxies can examine different modified gravity models.

Public Service Delivery Reform and Customer Satisfaction: the Case of Social Security Agency (SSA) and Document Authentication and Registration Office (DARO)
Creators: name: Tesfaw, Desta
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2008

description: Public service delivery has become the central focus of recent Public Sector Reforms (PSRs) throughout the world. The public service reform program is one of the components of the Ethiopian civil service reform program. The overall objective of this study is to identify and analyze the factors that determine the success and failure of the public service delivery reform in relation to customer satisfaction. The study has used the case study method by selecting two case organizations namely Social Security Agency (SSA) and Document Authentication and Registration Office (DARO). The data have been collected from primary and secondary sources through interview, questionnaire, observation and document reviewing. Based on the conceptual frame, the data have been presented and analyzed through comparative analysis of the case organizations. The findings of the analysis show that the two case organizations are different in satisfying customers in service delivery i.e. DARO satisfied its customers better than SSA. This study reveals that the differences in performance between the two case organizations are the result of organizational and motivational factors. The major organizational factors are vision and mission, service standards, customer complaint handling mechanisms, reengineering of working processes and application of Information Communication Technology (ICT). The major staff motivational factors are training, communication, performance appraisal and reward system, delegation for decision making and physical facilities. This study therefore concludes that these factors should be fulfilled at the organizational level to satisfy customers through public service delivery

Baryon asymmetry via leptogenesis in a neutrino mass model with complex scaling

description: Baryogenesis via leptogenesis is investigated in a specific model of light neutrino masses and mixing angles. The latter was proposed on the basis of an assumed complex-extended scaling property of the neutrino Majorana mass matrix $M_ν$, derived with a type-1 seesaw from a Dirac mass matrix $m_D$ and a heavy singlet neutrino Majorana mass matrix $M_R$. One of its important features, highlighted here, is that there is a common source of the origin of a nonzero $θ_{13}$ and the CP violating lepton asymmetry through the imaginary part of $m_D$. The model predicted CP violation to be maximal for the Dirac type and vanishing for the Majorana type. We assume strongly hierarchical mass eigenvalues for $M_R$. The leptonic CP asymmetry parameter $\varepsilon^α_{1}\hspace{1mm}$ with lepton flavor $α$, originating from the decays of the lightest of the heavy neutrinos $N_1$ (of mass $M_1$) at a temperature $T\sim M_1$, is what matters here with $\varepsilon^α_{2,3}$, originating from the decays of $N_{2,3}$, being washed out. The light leptonic and heavy neutrino number densities (normalized to the entropy density) are evolved via Boltzmann equations down to electroweak temperatures to yield a baryon asymmetry through sphaleronic transitions. The effect of flavored vs. unflavored leptogenesis in the three mass regimes (1) $M_1<10^{9}$ GeV, (2) $10^9$ GeV $10^{12}$ GeV are numerically worked out for both a normal and an inverted mass ordering of the light neutrinos. Corresponding results on the baryon asymmetry of the universe are obtained, displayed and discussed.

description: We approach multipartite entanglement classification in the symmetric subspace in terms of algebraic geometry, its natural language. We show that the class of symmetric separable states has the structure of a Veronese variety and that its $k$-secant varieties are SLOCC invariants. Thus SLOCC classes gather naturally into families. This classification presents useful properties such as a linear growth of the number of families with the number of particles, and nesting, i.e. upward consistency of the classification. We attach physical meaning to this classification through the required interaction length of parent Hamiltonians. We show that the states $W_N$ and GHZ$_N$ are in the same secant family and that, effectively, the former can be obtained in a limit from the latter. This limit is understood in terms of tangents, leading to a refinement of the previous families. We compute explicitly the classification of symmetric states with $N\leq 4$ qubits in terms of both secant families and its refinement using tangents. This paves the way to further use of projective varieties in algebraic geometry to solve open problems in entanglement theory.

description: Multi-wing chaotic attractors are highly complex nonlinear dynamical systems with higher number of index-2 equilibrium points. Due to the presence of several equilibrium points, randomness and hence the complexity of the state time series for these multi-wing chaotic systems is much higher than that of the conventional double-wing chaotic attractors. A real-coded Genetic Algorithm (GA) based global optimization framework has been adopted in this paper as a common template for designing optimum Proportional-Integral-Derivative (PID) controllers in order to control the state trajectories of four different multi-wing chaotic systems among the Lorenz family viz. Lu system, Chen system, Rucklidge (or Shimizu Morioka) system and Sprott-1 system. Robustness of the control scheme for different initial conditions of the multi-wing chaotic systems has also been shown.

description: Because in the machining process of concrete tool wear and production time are very cost sensitive factors the adaption of the tools to the particular machining processes is of major interest. We show how statistical methods can be used to model the influences of the process parameters to the forces affecting the workpiece as well as the chip removal rate and the wear rate of the used diamond. Based on these models a geometrical simulation model can be derived which will help to predetermine optimal parameter settings for specific situations. As the machined materials are in general abrasive, usual discretized simulation methods like Finite Elements Models can not be applied. Hence our approach is another type of discretization namely subdividing both material and diamond grain into their Delaunay tessellations and interpreting the resulting micropart connections as predetermined breaking points. Then the process is iteratively simulated and in each iteration the interesting entities are computed.

description: A conservative constraint on the rest mass of the photon can be estimated under the assumption that the frequency dependence of dispersion from astronomical sources is mainly contributed by the nonzero photon mass effect. Photon mass limits have been earlier set through the optical emissions of the Crab Nebula pulsar, but we prove that these limits can be significantly improved with the dispersion measure (DM) measurements of radio pulsars in the Large and Small Magellanic Clouds. The combination of DM measurements of pulsars and distances of the Magellanic Clouds provide a strict upper limit on the photon mass as low as $m_γ \leq2.0\times10^{-45}~\rm{g}$, which is at least four orders of magnitude smaller than the constraint from the Crab Nebula pulsar. Although our limit is not as tight as the current best result ($\sim10^{-47}~\rm{g}$) from a fast radio burst (FRB 150418) at a cosmological distance, the cosmological origin of FRB 150418 remains under debate; and our limit can reach the same high precision of FRB 150418 when it has an extragalactic origin ($\sim10^{-45}~\rm{g}$).

The contribution of FDI firms for technology transfer in the case of "Bole Lemi Industry Park" and "Eastern Industry Zone"

Publisher: name: National Academic Digital Repository of Ethiopia

description: Transfer of technology is the key element of the industrialization, growth and economic development of the countries. The transfer of technology through foreign firms would be effective if and only if when there is a high level of local participation and if there is a clear policy and binding law in which these foreign firms in the industry park and zone will engage in the capacity building activity for local firms. This study aims at exploring the level of linkage between foreign firms in the industry park and zone Vs local firms and how foreign firms in the industry park and zone engage in the technology capacity building activity of local firms and local personnel's directly or indirectly and also reviews the policies and laws in this specific topic.The quantitative and qualitative models have been significantly utilized in analyzing the contributing factors of technology transfer process. The main focus of this study is to evaluate the level of contribution of foreign firms specific in industry zone and parks for technology transfer by considering the foreign firms technological level and potential for technology flow.Majority of these foreign firms in industry park and zone export their products for European & American market.So to satisfy the end product consumers' needs, these firms used modern machineries and technologies to produce standard product. The conducted survey analysis shows that foreign firms found in industrial park & zone have a big potential for technology transfer for local firms and employees. But, it needs extra work to benefit from these firms as a means of least expensive technology transfer mechanism. The designed policies and laws regarding technology transfer from these firms need to review to encourage the firms through incentives or pre-arrangedinvestment agreements. To address the problem, the researcher proposes policy implications by putting the contributing factors to effectively transfer technologies from FDI firms.
