Year: 2011

description: An organized and efficient stock exchange has a positive impact on the economic growth by increasing saving and efficiently allocate capital to productive investments, allocate capital to corporate sector, increasing liquidity of financial assets etc. while this is the truth, it is difficult to predict the time in which a stock exchange will be established in our country. So I study to answer the question "should Ethiopia consider establishing of a stock exchange?" To answer this question I tried to collect data from shareholders, share companies respective managers, academicians and National Bank of Ethiopia"s officials in one hand and from previous writings in the area on the other hand. I found that even tough the preconditions are not fulfilled fully, this is the right time to start work to establish a stock exchange and we can start operation at a minimum level. But the government has to be involved fully and have to control, follow and supervise the process. Key Word: Stock exchange

description: The heavy fermion compound URu$_2$Si$_2$ continues to attract great interest due to the unidentified hidden order it develops below 17.5K. The unique Ising character of the spin fluctuations and low temperature quasiparticles is well established. We present detailed measurements of the angular anisotropy of the nonlinear magnetization that reveal a $\cos^4 θ$ Ising anisotropy both at and above the ordering transition. With Landau theory, we show this implies a strongly Ising character of the itinerant hidden order parameter.

description: Pluridisciplinary practices that span art and science are well-known in Western research and creative communities. Some of the most interesting and significant of these works confront audiences with deep questions about "life, the universe, and everything” (with apologies to Douglas Adams). But in the Global South—where addressing basic human needs, achieving economic and political security, and adapting to the unfolding climate crisis—are widely regarded as priorities, is there even space or time for the same? Using recent artscience research and creative projects I have been involved in, I argue that despite—or indeed because—of the challenges confronting the Global South, research, practice, and education on the intersections of the arts and the sciences is more necessary than ever.

description: Particle number fluctuations, no matter how small, are present in experimental set-ups. One should rigorously take these fluctuations into account, especially, for entanglement detection. In this context, we generalize the spin squeezing inequalities introduced by Tóth et al. in Phys. Rev. Lett. 99, 250405 (2007). These new inequalities are fulfilled by all separable states even when the number of particle is not constant, and may present quantum fluctuations. These inequalities are useful for detecting entanglement in many-body systems when the super-selection rule does not apply, or when only a subspace of the total systems Hilbert space is considered. We also define general dichotomic observables for which we obtain a coordinate independent form of the generalized spin squeezing inequalities. We give an example where our generalized coordinate independent spin squeezing inequalities present a clear advantage over the original ones.

description: Models of loop quantum gravity based on real connections have a deformed notion of general covariance, which leads to the phenomenon of signature change. This result is confirmed here in a general analysis of all midisuperspace models without local degrees of freedom. As a subclass of models, 2-dimensional theories of dilaton gravity appear, but a larger set of examples is possible based only on the condition of anomaly freedom. While the classical dilaton gravity models are the only such systems without deformed covariance, they do give rise to signature change when holonomy modifications are included.

description: Liquid-liquid transition is an intriguing phenomenon in which a liquid transforms into another liquid via the first-order transition. For molecular liquids, however, it always takes place in a supercooled liquid state metastable against crystallization, which has led to a number of serious debates concerning its origin: liquid-liquid transition vs. unusual nano-crystal formation. Thus, there have so far been no single example free from such debates. Here we show the first firm experimental evidence that the transition is truly liquid-liquid transition and not nano-crystallization for a molecular liquid, triphenyl phosphite. We kinetically isolate the reverse liquid-liquid transition from glass transition and crystallization with an extremely high heating rate of flash differential scanning calorimetry, and prove the reversibility and first-order nature of liquid-liquid transition. Our finding not only deepens our physical understanding of liquid-liquid transition but also will initiate a new phase of its research from both fundamental and applications viewpoints.

description: The Oulad Dlim massif in the southernmost part of Morocco hosts several carbonatite bodies of different ages. The older carbonatite (1.85 Ga) occurs in the eastern Oulad Dlim massif in the Gleibat Lafhouda area and consists of three juxtaposed magnesiocarbonatite outcrops. They are associated with glimmerite, hosted by Archean gneiss, and unusually intruded by massive IOA deposits. The latter contains up to several wt% REE related to numerous monazite-(Ce) inclusions within large apatite crystals. Columbite-(Fe) is the main Nb-mineral and occurs closely associated with Fe-phases, whereas microlite and Ta-rich columbite-(Fe) are mainly associated with coarse-grained apatites hosted by Fe-oxides and silica breccia. Geochemical characteristics and textural relationship suggest that they are genetically linked to the carbonatite and likely formed by late hydrothermal fluids at multiple stages. Small outcrops of nepheline syenite occur at several km from this carbonatite and might be genetically related. The youngest carbonatite (104 Ma) is a soevite and crops out within a ring structure composed of silica breccia and Fe-oxide mineralization at the Twihinat area of the western Oulad Dlim massif without visible associated alkaline rocks. All outcropping rocks at Twihinat show epigentic REE-Nb mineralization, mainly as bastnaesite within the carbonatite and silica breccia and monazite within the Fe-oxides. Pyrochlore senso-stricto occurs within the carbonatite, whereas cerio-pyrochlore is dominant in the silica breccia. The mineralogical and geochemical signatures of all Twihinat rocks suggest ore precipitation from multistage REE-Nb-rich hydrothermal fluids that percolated through the carbonatites and the associated rocks.

The analytical solution indicates a non-trivial phase diagram determined by the competition of the leading terms of the two processes. We test our results against numerical simulations, and compare the analytical predictions with an empirical dataset finding good agreements between them. The presented framework can be used to classify the dynamical features of real social networks and to gather new insights about the effects of social dynamics on ongoing spreading processes.

title: Scale and Bandwidth Extension of Power Converter–Based Impedance Spectroscopy
Creators: name: Sandschulte, Arne
Publisher: name: University of Liverpool Repository
Year: 2023

description: The ongoing energy transition from fossil fuels to renewable energy sources has led to a substantial rise in the use of electrochemical energy storage devices. For example, electric vehicles and energy storage for distributed generation are two applications in which batteries are being widely adopted as energy storage solutions. This research project is concerned with the development of diagnostic monitoring techniques for electrochemical energy storage devices, with a particular focus on lithium-ion batteries. Diagnostic monitoring is a critical part of systems employing such energy storage devices, as it ensures their safe, reliable, and efficient operation. This makes accurate diagnostic monitoring techniques essential for the successful adoption of the aforementioned technologies. Electrochemical Impedance Spectroscopy (EIS) is an established technique that is used widely in the characterisation of electrochemical systems, including batteries. Recent work has focused on a novel power converter-based EIS implementation, which has the potential of making EIS accessible outside of research laboratories. The aim of this work is to contribute to the development of the power converter–based EIS technique, focusing primarily on extending its scale and bandwidth. A method is presented to compensate for variations in the state of charge, allowing the measurement bandwidth to be extended to frequencies in the millihertz range. Further, a strategy is developed to extend the upper end of the measurement bandwidth when the available sampling rate is limited. An experimental setup involving signal acquisition and real-time control capabilities is built. Experimental results allow the correct operation of the system to be validated, thus permitting for the first time a battery pack consisting of 16 series-connected lithium iron phosphate cells to be monitored using the power converter-based EIS method. With the batteries discharging at a dc current of 20 A, the controller is able to introduce the ac current perturbations in the range from 10 mHz up to 100 Hz. The measurement precision is shown to be high enough to allow meaningful impedance variations to be detected: both due to small differences between cells in a battery pack, and also due to changes in the state of charge.
Slashing the Final Frontier: Star Trek, Representations of Queer(ed) Media, and the Effect of Participatory Culture(s)
Creators: name: Girard, Danielle
Publisher: name: Lancaster University
Year: 2022

description: Slashing the Frontier is a cultural intervention on the depiction of queer representations in the popular television property Star Trek. This project crafts an original methodology of reading queered media (media touched by slash fanfiction). I argue that by introducing romantic orientation into the academic lexicon, the previously diverging modes of queer studies and fandom studies are allowed to overlap. In turn, this allots freedom to repurposing intentional and unintentional queer subtext into a working formula that creates a space for contemporary understandings of queerness to thrive. I ask what purpose ‘canon’ serves to the popular culture imagination and conclude that previously understood notions of a fixed ‘canon’ are inherent falsehoods. The popular culture canon, I argue, remains in a constant state of flux that relies heavily on paratextual material and the collective popular memory. With a textual focus on Star Trek: The Original Series (1964-69), the six Star Trek films released from 1979-1991, and the three Star Trek reboot films (2009, 2013, 2016), this thesis spans a 50+ year period of transformative fandom. The history of queer pairings within fandom remains murky, but it is a incontestable fact that the reception of the relationship between Kirk and Spock forever changed the makeup of fandom and fan practices. Using them as a vehicle for my argument then permits me to trace the cultural history and impact of slash fanfiction in a way distinctly separate from the socio-political readings done by scholars such as Jenkins, Bacon-Smith, and Penley. I argue that as slash gained cultural capital and elevated feminine aspects of fandom to positions of power, the methods of creating, producing, and marketing television forever changed, leaving ‘tradition’ behind in favour of a sexually and romantically diverse queer media landscape.

description: Quantum Hamiltonian identification is important for characterizing the dynamics of quantum systems, calibrating quantum devices and achieving precise quantum control. In this paper, an effective two-step optimization (TSO) quantum Hamiltonian identification algorithm is developed within the framework of quantum process tomography. In the identification method, different probe states are inputted into quantum systems and the output states are estimated using the quantum state tomography protocol via linear regression estimation. The time-independent system Hamiltonian is reconstructed based on the experimental data for the output states. The Hamiltonian identification method has computational complexity O(d^6) where d is the dimension of the system Hamiltonian. An error upper bound O(d^3/N^(1/2))$ is also established, where N is the resource number for the tomography of each output state, and several numerical examples demonstrate the effectiveness of the proposed TSO Hamiltonian identification method.

Assessment of Customer Satisfaction on Multi-modal Transport System: The Case of Selected Private Import Businesses
Creators: name: Tadesse, Belay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: The primary objective of this study was to assess customer satisfaction on multimodal transport system as evidenced from users (private import business) perspective. Multimodal transport service, logistics service value, and customer service relationship quality, have been utilized as measurement constructs to assess the level of customer satisfaction. In this study, the customer satisfaction has been rigorously studied. The constructs have been properly operationalized to develop, the survey questionnaires used to collect data. A quantitative method has been applied to analyze the data collected from importers operating in Addis Ababa. The findings of the statistical analysis have shown that importers have been relatively dissatisfied on the multimodal transport service. They have not been feeling that the current multimodal operator has been delivering the logistics service value for money and they have been indifferent to the customer service relationship quality. The study has also shown that there are no statistically significant relations between the indicators, which support the null hypotheses as well. In summary, this study has empirically assessed the multimodal transport system has contributed insignificantly to enhance importers business performance in Addis Ababa. And importers businesses have not been improved due to the service values of the current MTO in Ethiopia. This will provoke the need for furthers research at national level in order to assure the theoretically supported effect of the multimodal transport service on private businesses.

description: Gears are rotating machines, meshing with each other by teeth to transmit torque. Interestingly, the rotating directions of two meshing gears are opposite, clockwise and counterclockwise. Although this opposite handedness motion has been widely investigated in machinery science, the analogue behavior of photons remains undiscovered. Here, we present a simple nanophotonic directional coupler structure which can generate two meshing gears of angular momentum (AM) of light, optical gears. Due to the abrupt phase shift effect and birefringence effect, the AM states of photons vary with the propagation distance in two adjacent waveguides of the coupler. Thus, by the choice of coupling length, it is able to obtain two light beams with opposite handedness of AM, confirming the appearance of optical gears. The full control in the handedness of output beams is achieved via tuning the relative phase between two orthogonal modes at the input ports. Optical gears thus offer the possibility of exploring light-matter interactions in nanoscale, opening up new avenues in fields of integrated quantum computing and nanoscale bio-sensing of chiral molecules.

description: Support Vector Data Description (SVDD) is a machine learning technique used for single class classification and outlier detection. SVDD based K-chart was first introduced by Sun and Tsung for monitoring multivariate processes when underlying distribution of process parameters or quality characteristics depart from Normality. The method first trains a SVDD model on data obtained from stable or in-control operations of the process to obtain a threshold $R^2$ and kernel center a. For each new observation, its Kernel distance from the Kernel center a is calculated. The kernel distance is compared against the threshold $R^2$ to determine if the observation is within the control limits. The non-parametric K-chart provides an attractive alternative to the traditional control charts such as the Hotelling's $T^2$ charts when distribution of the underlying multivariate data is either non-normal or is unknown. But there are challenges when K-chart is deployed in practice. The K-chart requires calculating kernel distance of each new observation but there are no guidelines on how to interpret the kernel distance plot and infer about shifts in process mean or changes in process variation. This limits the application of K-charts in big-data applications such as equipment health monitoring, where observations are generated at a very high frequency. In this scenario, the analyst using the K-chart is inundated with kernel distance results at a very high frequency, generally without any recourse for detecting presence of any assignable causes of variation. We propose a new SVDD based control chart, called as $K_T$ chart, which addresses challenges encountered when using K-chart for big-data applications. The $K_T$ charts can be used to simultaneously track process variation and central tendency. We illustrate the successful use of $K_T$ chart using the Tennessee Eastman process data.

description: In order to study the nature, origin, and impact of turbulent velocity fluctuations in the ionized gas of the Orion Nebula, we apply a variety of statistical techniques to observed velocity cubes. The cubes are derived from high resolving power ($R \approx 40,000$) longslit spectroscopy of optical emission lines that span a range of ionizations. From Velocity Channel Analysis (VCA), we find that the slope of the velocity power spectrum is consistent with predictions of Kolmogorov theory between scales of 8 and 22 arcsec (0.02 to 0.05 pc). The outer scale, which is the dominant scale of density fluctuations in the nebula, approximately coincides with the autocorrelation length of the velocity fluctuations that we determine from the second order velocity structure function. We propose that this is the principal driving scale of the turbulence, which originates in the autocorrelation length of dense cores in the Orion molecular filament. By combining analysis of the non-thermal line widths with the systematic trends of velocity centroid versus ionization, we find that the global champagne flow and smaller scale turbulence each contribute in equal measure to the total velocity dispersion, with respective root-mean-square widths of 4-5 km/s. The turbulence is subsonic and can account for only one half of the derived variance in ionized density, with the remaining variance provided by density gradients in photoevaporation flows from globules and filaments. Intercomparison with results from simulations implies that the ionized gas is confined to a thick shell and does not fill the interior of the nebula.

description: We present the first study of GALEX far ultra-violet (FUV) luminosity functions of individual star-forming regions within a sample of 258 nearby galaxies spanning a large range in total stellar mass and star formation properties. We identify ~65,000 star-forming regions (i.e., FUV sources), measure each galaxy's luminosity function, and characterize the relationships between the luminosity function slope (alpha) and several global galaxy properties. A final sample of 82 galaxies with reliable luminosity functions are used to define these relationships and represent the largest sample of galaxies with the largest range of galaxy properties used to study the connection between luminosity function properties and galaxy environment. We find that alpha correlates with global star formation properties, where galaxies with higher star formation rates and star formation rate densities (Sigma_SFR) tend to have flatter luminosity function slopes. In addition, we find that neither stochastic sampling of the luminosity function in galaxies with low-number statistics nor the effects of blending due to distance can fully account for these trends. We hypothesize that the flatter slopes in high Sigma_SFR galaxies is due to higher gas densities and higher star formation efficiencies which result in proportionally greater numbers of bright star-forming regions. Finally, we create a composite luminosity function composed of star-forming regions from many galaxies and find a break in the luminosity function at brighter luminosities. However, we find that this break is an artifact of varying detection limits for galaxies at different distances.

Project Work on the Role of Higher Educational Institutions in Organization Leadership Development

description: "Whoever heard of a world manager? World leader, yes. Education leader, yes. Political leader. Religious leader. Football leader. Community leader and Business leader" John C. Maxwell, Developing the Leader within You. Organizations which achieve sustainable growth ascribe their success mainly to their competent leaders who set direction and lead the organization towards it by maximizing the organization's competitive advantage and minimizing its risk. Leadership is not exclusive club for those who were "born with it" rather leadership is a set of behavioral skills which can be developed. Even though approaches to leadership development vary due to the complexity of leadership and particular need assessment, three forms of leadership development: formal training, experience (developmental activities), and self-help activities. In Ethiopian context, it seems that organizational leadership development is not in short supply rather it is not supplied at all. Government and non-government higher educational institutions are flourishing; however, none of them are engaged in organizational leadership development at program level or offers leadership as a course in postgraduate program except International Leadership Institute that facilitates Azuza Pacific (California based) University's Masters Degree in Organizational Leadership and offer BachelorDegree in Organization Management. With such shortage of qualified human resources in organization leadership, organization success in today's turbulent environment is doubtful. To this effect leadership concept is not understood by most organization members in Ethiopia. The two main reasons identified for lack of conceptual understanding in leadership are absence of higher educational institutions on leadership and lack of training on leadership. Organization members do not recognize the importance of leadership for their organization's success mainly due to belief that power is more important than effective leadership and consideration of management and leadership as one and the same. The education on leadership offered by Azuza Pacific University's and facilitated by International Leadership Institute is said excellent in terms of course content, teaching methodology, academic staff capacity, and duration of the program. Grading system, follow-up and feed back mechanism, and reference materials availability are relatively the weak areas of ILI. The leadership program of Azuza Pacific University is said to be very expensive and is not adequate to meet the very high demand for organizational leadership development in Ethiopia. The main option cited is for both government and Non-government Higher Educational Institutions to engage in organizational leadership development.

Creators: name: Tulu, Dejene
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: In this research, the impact of ISO certification on the performance of the companies was studied. This is mainly due to the reason that companies often claim ISO certification can improve the performance of the organization. To investigate this, secondary data of five brewery companies in Ethiopia is collected. The data cover operational activities of the companies over the period of ten years and it is of before and after ISO certification. The collected data was analysed using descriptive statistics and tested for its significance. The model specified is the panel data of five brewery companies over a period of ten years with the help of OLS estimation. The results showed that ISO certification has a significant impact on the companies" performance. The finding also indicated that, after ISO certification the companies have acquired improvements on their total sales. Further study is suggested to investigate the impact of ISO certification on company performance, particularly for Ethiopian Companies.

Year: 2021

description: Hydrothermal activity, triggered by endogenic processes, distributes and redistributes organic matter through diffuse flow networks and may lead to a production of organic matter via abiotic synthesis. Today, hydrothermal seepage, especially at seafloor spreading zones, induces oases for diverse microbial communities in otherwise relatively hostile environments. Furthermore, hydrothermal fluids can deliver organic molecules as building blocks and/or substrates for primeval microorganisms and thus probably played a central role in the emergence of life on Earth. In this talk I will briefly outline evidence for traces of early life on Earth associated with hydrothermal processes from the 3.5 Ga old Dresser Formation (Pilbara, Western Australia). Recent findings strongly support the idea that microbial life in the Dresser Formation was linked to, and perhaps locally fuelled by, hydrothermal seepage. I will demonstrate that integrative study designs including analytical imaging techniques (e.g., Raman spectroscopy), biogeochemical approaches (e.g., catalytic hydropyrolysis and gas chromatography – mass spectrometry), stable isotope analysis and experimental approaches provide important insights into the complex interplay between biological and abiotic processes in early Archean hydrothermal habitats. Thus, they allow us to catch a glimpse into the earliest record of life on Earth.
Challenges and Opportunities of Managing the Telecom Sector:The Case of Ethio Telecom

description: Telecommunication is the transmission of information over significant distances to communicate. The strong development of telecommunication would help to improve efficiency of the economy and the country's competitiveness which promote economic and social development. Telecom will change the way humans work, play, and live. The International Telecommunications Union (ITU, 2015) reported that there are more in-use cell phones than there are people on the planet already. Continuous technical transformation and information waves of the past century have driven high growth in the telecom industry. However, telecom companies are facing challenges as well as opportunities in their business endeavor. Hence, the purpose of this research is to investigate and examine the challenges and opportunities of managing the telecom sector of Ethiopia, with particular focus on ethio telecom. The method employed in the research is qualitative research method. Data is collected from both primary and secondary sources using the techniques of indepth interview, direct observation, document review and analysis. Accordingly, it is found out that technological advancement, and telecom fraud are among the major challenges and opportunities of Ethiopian Telecom Sector. Moreover, it is found out that WTO accession will create new opportunities and as well will impose new challenges to the telecommunications sector of Ethiopia. Hence, ethio telecom and the Government shall create strategic alliance and partnership with high technology companies around the World, implement a fraud management system that detect frauds before it happen and damage occurs, implement appropriate policies and strategies to avoid the risks and grasp the opportunities of joining WTO, and establish Research and Development Center of Telecom for sustained development of the Telecom Industry of Ethiopia.

description: We present a comprehensive analysis of longitudinal particle drifting in a standing circularly polarized wave at extreme intensities when quantum radiation reaction (RR) effects should be accounted for. To get an insight into the physics of this phenomenon we made a comparative study considering the RR force in the Landau-Lifshitz or quantum-corrected form, including the case of photon emission stochasticity. It is shown that the cases of circular and linear polarization are qualitatively different. Moreover, specific features of particle dynamics have a strong impact on spatial structures of the electron-positron ($e^-e^+$) density created in vacuum through quantum electrodynamic (QED) cascades in counter-propagating laser pulses. 3D PIC modeling accounting for QED effects confirms realization of different pair plasma structures.

description: We show that scattering amplitudes in planar N = 4 Super Yang-Mills in multi-Regge kinematics can naturally be expressed in terms of single-valued iterated integrals on the moduli space of Riemann spheres with marked points. As a consequence, scattering amplitudes in this limit can be expressed as convolutions that can easily be computed using Stokes' theorem. We apply this framework to MHV amplitudes to leading-logarithmic accuracy (LLA), and we prove that at L loops all MHV amplitudes are determined by amplitudes with up to L + 4 external legs. We also investigate non-MHV amplitudes, and we show that they can be obtained by convoluting the MHV results with a certain helicity flip kernel. We classify all leading singularities that appear at LLA in the Regge limit for arbitrary helicity configurations and any number of external legs. Finally, we use our new framework to obtain explicit analytic results at LLA for all MHV amplitudes up to five loops and all non-MHV amplitudes with up to eight external legs and four loops.

description: We present a general surface brightness correction method for compact extended sources imaged in the slow-scan pointed observation mode of the Far-Infrared Surveyor (FIS) aboard the AKARI Infrared Astronomical Satellite. Our method recovers correct surface brightness distribution maps by re-scaling archived raw FIS maps using the surface-brightness-dependent inverse FIS response function. The flux of a target source is then automatically corrected for as the simple sum of surface brightnesses within the adopted contour encircling the perimeter of the target (i.e., contour photometry). This correction method is contrasted to the previous aperture photometry method for point sources, which directly corrects for the target flux with a flux-dependent scaling law. The new surface brightness correction scheme is applicable to objects of any shape from unresolved point sources to resolved extended objects, as long as the target is not deemed diffuse, i.e., the total extent of the target source does not exceed too much more than a single FIS scan width of 10 arcmin. The new correction method takes advantage of the well-defined shape (i.e., the scale invariance) of the point-spread function, which enables us to adopt a power-law FIS response function. We analyze the point-source photometric calibrator data using the FIS AKARI Slow-scan Tool (FAST) and constrained the parameters of the adopted power-law FIS response function. We conclude that the photometric accuracy of the new correction method is better than 10% error based on comparisons with the expected fluxes of the photometric calibrators and that resulting fluxes without the present correction method can lead up to 230% overestimates or down to 50% underestimates.
