description: Content delivery success in wireless caching helper networks depends mainly on cache-based channel selection diversity and network interference. For given channel fading and network geometry, both channel selection diversity and network interference dynamically vary according to what and how the caching helpers cache at their finite storage space. We study probabilistic content placement (or caching placement) to desirably control cache-based channel selection diversity and network interference in a stochastic wireless caching helper network, with sophisticated considerations of wireless fading channels, interactions among multiple users such as interference and loads at caching helpers, and arbitrary memory size. Using stochastic geometry, we derive optimal caching probabilities in closed form to maximize the average success probability of content delivery and propose an efficient algorithm to find the solution in a noise-limited network. In an interference-limited network, based on a lower bound of the average success probability of content delivery, we find near-optimal caching probabilities in closed form to control the channel selection diversity and the network interference. We numerically verify that the proposed content placement is superior to other comparable content placement strategies.

description: The negatively-charged nitrogen-vacancy (NV-) center in diamond is the focus of widespread attention for applications ranging from quantum information processing to nanoscale metrology. Although most work so far has focused on the NV- optical and spin properties, control of the charge state promises complementary opportunities. One intriguing possibility is the long-term storage of information, a notion we hereby introduce using NV rich, type-1b diamond. As a proof of principle, we use multi-color optical microscopy to read, write, and reset arbitrary data sets with 2-D binary bit density comparable to present digital-video-disk (DVD) technology. Leveraging on the singular dynamics of NV- ionization, we encode information on different planes of the diamond crystal with no cross talk, hence extending the storage capacity to three dimensions. Further, we correlate the center's charge state and nuclear spin polarization of the nitrogen host, and show that the latter is robust to a cycle of NV- ionization and recharge. In combination with super-resolution microscopy techniques, these observations provide a route towards sub-diffraction NV charge control, a regime where the storage capacity could exceed present technologies.

Prediction of Rolling Noise Due to Wheel/Rail Interaction
Creators: name: Hassen, Mohammed
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Noise, caused by the interaction of steel wheel rolling on the steel rail is always present. The noise radiated by the railway system has significant influences on both passengers inside the trains and the residents along the railway lines. To overcome this problem, first we have to predict the noise level by applying and varying different parameters, like wheel load, materials of the wheel and rail, operating speed and so on. But in this paper i mainly consider only train operating speed to predict the noise generated between the contacting surfaces which is obtained from the contact pressure. The objective of this research is to predict the noise generated between wheel/rail by applying different operating speed. The maximum contact pressure during the operation of the train is used to predict the noise level. This research is done by developing the 3D model using CATIA V5 R16, simulation using ANSYS v14.5 and analytical calculation. In this research, the value of average maximum contact pressure obtained by simulation of ANSYS software on the whole area of ellipse (contact patch) is 511.7 . This is due to the operating speed 80km/h and the minimum contact pressure on the whole area of ellipse is 351.68 Mpa when the operating speed is 60km/h, the corresponding sound pressures are 268.15 dB and 264.9 dB respectively. From the results, high speed is the cause of high contact pressure and this high contact pressure is the cause of high noise.

description: We study the ground state of a bilayer system of dipolar bosons with dipoles oriented by an external field perpendicularly to the two parallel planes. By decreasing the interlayer distance, for a fixed value of the strength of the dipolar interaction, the system undergoes a quantum phase transition from an atomic to a pair superfluid. We investigate the excitation spectrum across this transition by using microscopic approaches. Quantum Monte Carlo methods are employed to obtain the static structure factors and intermediate scattering functions in imaginary time. The dynamic response is calculated using both the correlated basis functions (CBF) method and the approximate inversion of the Laplace transform of the quantum Monte Carlo imaginary time data. In the atomic phase, both density and spin excitations are gapless. However, in the pair-superfluid phase a gap opens in the excitation energy of the spin mode. For small separation between layers, the minimal spin excitation energy equals the binding energy of a dimer and is twice the gap value.

Harmonic Analysis in 25kV AC Railway Electrification system: The case of the proposed Ethiopian Railway System
Creators: name: Henok, Million
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Electrical locomotives generate harmonic currents in railway power-supply system. Which in turn produce continuous distortion of current and voltage waveform in the supply network. This distortion gives adverse effect in traction power-supply system such as overheating, vibration and torque reduction of rotating machines, additional losses of lines and transformers, interference with communication systems, malfunctions of protection relays, measuring instrument error, etc. Therefore, the distortion in voltage and current waveform at various points in the traction system should be quantified and analyzed according to international standards such as IEEE 519-1999. This thesis focuses on studying voltage and current distortion in the supply system due to harmonics injected by locomotive with diode rectifier. The system considered under study for harmonics analysis is a proposed Ethiopian single-phase 25KV AC electrification system. Major components of the electric traction system are modeled for harmonic study using MATLAB/SIMPOWER system. Added to this, mathematical model of supply network to quantify voltage distortion at different bus analytically is developed. The systems without harmonic filter have been simulated to investigate the harmonic levels for different operating conditions. Accordingly, the simulation result at PCC for train at full load reveals that a THD of 11.26% for voltage and a THD of 37.15% for current in worst scenario. This is large as compere to the limit set by IEEE 519-1999.Therefore, a passive harmonic LC filter is designed to filter out the noticeable harmonics in the system. As the result, it was found that THD of 3.13% for voltage and THD of 3.15% for current waveform, which are below IEEE 519 standard, limits. This shows power quality and EMC improvement of the traction power supply system.
Derivation of human chromatic discrimination ability from an information-theoretical notion of distance in color space

Year: 2016

description: The accuracy with which humans can detect small chromatic differences varies throughout color space. For example, we are far more precise when discriminating two similar orange stimuli than two similar green stimuli. In order for two colors to be perceived as different, the neurons representing chromatic information must respond differently, and the difference must be larger than the trial-to-trial variability of the response to each separate color. Photoreceptors constitute the first stage in the processing of color information; many more stages are required before humans can consciously report whether two stimuli are perceived as chromatically distinguishable or not. Therefore, although photoreceptor absorption curves are expected to influence the accuracy of conscious discriminability, there is no reason to believe that they should suffice to explain it. Here we develop information-theoretical tools based on the Fisher metric that demonstrate that photoreceptor absorption properties explain ~87% of the variance of human color discrimination ability, as tested by previous behavioral experiments. In the context of this theory, the bottleneck in chromatic information processing is determined by photoreceptor absorption characteristics. Subsequent encoding stages modify only marginally the chromatic discriminability at the photoreceptor level.

description: The migration of robots from the laboratory into sensitive home settings as commercially available therapeutic agents represents a significant transition for information privacy and ethical imperatives. We present new privacy paradigms and apply the Fair Information Practices (FIPs) to investigate concerns unique to the placement of therapeutic robots in private home contexts. We then explore the importance and utility of research ethics as operationalized by existing human subjects research frameworks to guide the consideration of therapeutic robotic users -- a step vital to the continued research and development of these platforms. Together, privacy and research ethics frameworks provide two complementary approaches to protect users and ensure responsible yet robust information sharing for technology development. We make recommendations for the implementation of these principles -- paying particular attention to specific principles that apply to vulnerable individuals (i.e., children, disabled, or elderly persons)--to promote the adoption and continued improvement of long-term, responsible, and research-enabled robotics in private settings.

Enhanced Peak-to-Average Power Ratio Reduction Technique In 0fdm Communication Systems
Creators: name: Abera, Mengistu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: The Orthogonal Frequency Division Multiplexing (OFDM) is a strong candidate for the current and future wireless communications system due to its high data rates transmission capability and robustness against multi-path fading effects. A major drawback of OFDM is its high peak to average power ratio (PAPR). Since most practical transmission systems are peak power limited, the average transmit power should be reduced for linear operation over the full dynamic range, which degrades the received signal power. In this thesis we review the most popular OFDM PAPR-reduction techniques and demonstrate in detail that Selected Mapping (SLM) scheme is a particularly promising reduction technique. In a SLM system, an OFDM symbol is mapped to a set of independent but equivalent symbols and then the lowest-PAPR symbol is selected for transmission. The tradeoff for PAPR reduction in SLM is computational complexity as each mapping requires an additional inverse fast Fourier transform (IFFT) operation in the transmitter. An enhanced SLM method is proposed for computational complexity reduction. The proposed SLM scheme transforms an input symbol sequence into a set of OFDM signals by multiplying the phase sequences by the signal after a certain intermediate stage of inverse fast Fourier transform (IFFT). The enhanced SLM technique reduces computational complexity by 48% while it shows almost the same performance of PAPR reduction as that of the conventional SLM OFDM scheme.

description: The reliable computation time (RCT, marked as Tc) when applying a double precision computation of a variable parameters logistic map (VPLM) is studied. First, using the method proposed, the reliable solutions for the logistic map are obtained. Second, for a time-dependent non-stationary parameters VPLM, 10000 samples of reliable experiments are constructed, and the mean Tc is then computed. The results indicate that for each different initial value, the Tcs of the VPLM are generally different. However, the mean Tc trends to a constant value once the sample number is large enough. The maximum, minimum and probable distribution function of Tc is also obtained, which can help us to identify the robustness of applying a nonlinear time series theory to forecasting while using the VPLM output. In addition, the Tc of the fixed parameter experiments of the logistic map was obtained, and the results suggested that this Tc matches the theoretical formula predicted value.

description: Topological insulators are new class of quantum materials, which have insulating energy gaps in bulk, but exhibit gapless edge states or surface states that are protected by time-reversal symmetry at boundary. It was theoretically predicted and experimentally confirmed that the binary tetradymites Bi2Te3, Bi2Se3, and Sb2Te3 are three-dimensional topological insulators. In this work, we demonstrate by first-principles approach that the ignored Sb2Se3, although with relatively smaller spin-orbital coupling strength, can also exhibit topologically protected surface states with a bulk gap of 0.19 eV, as long as the van der Waals interaction is explicitly included in the calculations. Detailed analysis of the band structures of Sb2Se3 thin films indicates that the non-trivial surface state appears at a critical thickness of six quintuple layers.
Pressures and Flows in Foams and Ultrathin Foam Films

Year: 2023

description: Freestanding liquid films or foam films containing dispersed supramolecular structures, including self-assembled structures (like micelles) and macromolecules (like polymers), arise in cleaning, personal care, food, and pharmaceutical foams. The confinement-induced structuring and layering of these supramolecular structures in ultrathin foam films (thickness, h < 100 nm) provide a non-DLVO, oscillatory structural disjoining pressure. The interplay of capillary pressure and oscillatory disjoining pressure drives drainage via stratification, associated with stepwise thinning and coexisting thick-thin regions. Stratification proceeds by nucleation and growth of thinner domains at the expense of surrounding the thicker film. The expansion speeds up after spots thicker than the surrounding appear at the moving front, and the formation, shape and size of spots remain largely unexplored. Here, using IDIOM (interferometry, digital imaging, optical microscopy) protocols developed recently for visualizing and analyzing the nanotopography of stratifying foam films, we show that the spots are like mesas, with thickness in 10s of nm but width in microns. A tutorial introduction to IDIOM protocols is included to facilitate future studies on thickness mapping with exquisite spatiotemporal resolution (thickness < 10 nm, lateral < 1 μm, temporal < 1 ms). The shape and size evolution of nanoscopic mesas growing along the moving front is characterized, and we show that scaled shapes are identical for mesas irrespective of timespan after formation or surfactant concentration. We develop a theoretical model based on the thin film equation amended with disjoining pressure and show the width, height and shape of mesas follow similarity solutions quantitatively. The coalescence of mesas is analyzed for the first time to show a coalescence preference with ratio of azimuthal position shifts in moving frame showing quadratic dependence on inverse of mesa sizes. Lastly, we show that the foam films with a dilute amount of neutral polymers to micellar surfactant solutions exhibit all signatures of stratification. We present the first comprehensive evidence for stratification in neutral polymer-surfactant complexes. We determine that for surfactant concentrations beyond the excess micelle point, polymer addition and complexation impact the nanotopography but not the step-size, implying the amplitude of disjoining pressure changes, but the periodicity remains unchanged.
Development of Material for Train Overhead Contact Wire

description: This paper presents the development of material for train overhead contact wire. In view of the current Addis Ababa Light Rail Train overhead contact wire with high material cost and low wear resistance ; the copper alloys which has better mechanical wear and corrosion resistance with moderately low cost, are developed. The mechanical properties and electrical conductivities of the prepared copper alloys were investigated by using lab testing machines. Wear tests were conducted by a pin- on-disc Tribometer which simulated the tribological conditions of sliding contact strip on overhead wires in the railway system. The copper-alloys in the form of cylindrical pins were forced to slide against a stainless steel disc with a sliding velocity of 80 km/h at room temperature under unlubricated condition and normal load up to 11N without electric current. In addition to this, the electrical conductivity of the copper alloys were investigated by multimeter . Among the alloys investigated, CuNiCr, which possesses quite good electrical conductivity and relatively high wear resistance (2 times that of Cu Ag) .Also in order to simulate costal and acidic environment, corrosion test is conducted in acid rain, salt solution and in distilled water. The corrosion from the specimens was studied by weight loss measured by analytical balance among the copper alloys Cu Ag is highly corroded and worn surfaces of the copper alloys pin were analyzed by optical microscope from these parallel and continuous scratches in the direction of motion observed. From this experimental investigation the dominated wear mechanisms are abrasive and adhesive wear in mechanical sliding frictional process. Finally the cost analysis of copper alloys per each pin performed and Cu- Ni -Cr takes less cost from others. By considering wear resistance, corrosion resistance, electrical conductivity and cost, Cu Ni Cr is appropriate for Addis Ababa light rail train and future national railway overhead line contact wire.

description: We demonstrate that the investigations of the forward-backward correlations between intensive observables enable to obtain more clear signal about the initial stage of hadronic interaction, e.g. about the process of string fusion, compared to usual forward-backward multiplicity correlations. As an example, the correlation between mean-event transverse momenta of charged particles in separated rapidity intervals is considered. We performed calculations in the framework of dipole-based Monte Carlo string fusion model. We obtained the dependence of the correlation strength on the collision centrality for different initial energies and colliding systems. It is shown that the dependence reveals the decline of the correlation coefficient for most central Pb-Pb collisions at LHC energy. We compare the results both with the ones obtained in alternative models and with the ones obtained by us using various MC generators.

Challenges of Practical Implementation of IFRS in Ethiopia, Evidence from Banking Sector
Creators: name: Aytenew, Agumas
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Since the turn of the century, there is an unprecedented appreciation of the usefulness of the International Financial Reporting Standards (IFRS) across the globe. As a single set of globally converged, high quality accounting standards, IFRS are designed to serve as a common global language for business affairs so that company accounts are understandable and comparable across the globe. As a result, by recognizing the relative importance of IFRS, over 150 countries required or permitted IFRS as their corporate financial reporting standard. Despite this widespread acceptance of IFRS, there are serious institutional, enforcement and technical challenges that countries need to overcome in order to benefit fully from the introduction of IFRS in their jurisdictions. Ethiopia is one of those countries that face serious challenges to implement IFRS. Therefore, this research is intended to investigate the practical challenges of IFRS adoption in Ethiopia, particularly in private commercial banks. To achieve this objective, both primary and secondary data were collected from IFRS implementation team members of 12 private banks who were selected purposively based on their role and involvement in the implementation process. Primary data were collected through questionnaire and interview whereas secondary based were collected through documentary evidence and analyzed by using different descriptive statistical tools. Finally, the result of the study revealed that weak corporate governance, poor quality of education and training, lack of supports from accountancy professional bodies, weak enforcements of regulatory body, inadequacy of transition period, improper planning, nonavailability of transparent market information, high cost of implementation and weak management support are the major challenges of adopting IFRS by private banks in Ethiopia

description: Alopecia areata (AA) involves an aberrant immune attack on the hair follicle (HF), which leads to hair loss. Previous genetic data from our lab pointed to a connection between macroautophagy/autophagy and AA pathogenesis, and GWAS identified STX17, CLEC16A and BCL2L11/BIM as risk factors for AA. Additionally, AA patients have copy number deletions in region spanning the ATG4B gene. To test whether autophagy might contribute to disease pathogenesis in AA, we investigated autophagic activity in C3H/HeJ mouse model. We found that autophagy protein SQSTM1 accumulated in HF of AA mice, while in immune cells from AA skin-draining lymph nodes SQSTM1 was not altered, suggesting that autophagic activity is inhibited in the HF of AA mice. Induction of autophagy with Tat-BECN1 peptide attenuated AA, while treatment with the autophagy blocker chloroquine promoted disease, compared to untreated AA mice. Together, our findings suggest the involvement of impaired autophagy in disease pathogenesis of AA.

description: We study a stochastic model of gene expression, in which protein production has a form of random bursts whose size distribution is arbitrary, whereas protein decay is a first-order reaction. We find exact analytical expressions for the time evolution of the cumulant-generating function for the most general case when both the burst size probability distribution and the model parameters depend on time in an arbitrary (e.g. oscillatory) manner, and for arbitrary initial conditions. We show that in the case of periodic external activation and constant protein degradation rate, the response of the gene is analogous to the RC low-pass filter, where slow oscillations of the external driving have a greater effect on gene expression than the fast ones. We also demonstrate that the $n$-th cumulant of the protein number distribution depends on the $n$-th moment of the burst size distribution. We use these results to show that different measures of noise (coefficient of variation, Fano factor, fractional change of variance) may vary in time in a different manner. Therefore, any biological hypothesis of evolutionary optimization based on the nonmonotonicity of a chosen measure of noise must justify why it assumes that biological evolution quantifies noise in that particular way. Finally, we show that not only for exponentially distributed burst sizes but also for a wider class of burst size distributions (e.g. Dirac delta and gamma) the control of gene expression level by burst frequency modulation gives rise to proportional scaling of variance of the protein number distribution to its mean, whereas the control by amplitude modulation implies proportionality of protein number variance to the mean squared.

description: The yeast PROPPIN Atg18 folds as a β-propeller with two binding sites for phosphatidylinositol-3-phosphate (PtdIns3P) and PtdIns(3,5)P2 at its circumference. Membrane insertion of an amphipathic loop of Atg18 leads to membrane tubulation and fission. Atg18 has known functions at the PAS during macroautophagy, but the functional relevance of its endosomal and vacuolar pool is not well understood. Here we show in a proximity-dependent labeling approach and by co-immunoprecipitations that Atg18 interacts with Vps35, a central component of the retromer complex. The binding of Atg18 to Vps35 is competitive with the sorting nexin dimer Vps5 and Vps17. This suggests that Atg18 within the retromer can substitute for both the phosphoinositide binding and the membrane bending capabilities of these sorting nexins. Indeed, we found that Atg18-retromer is required for PtdIns(3,5)P2-dependent vacuolar fragmentation during hyperosmotic stress. The Atg18-retromer is further involved in the normal sorting of the integral membrane protein Atg9. However, PtdIns3P-dependent macroautophagy and the selective cytoplasm-to-vacuole targeting (Cvt) pathway are only partially affected by the Atg18-retromer. We expect that this is due to the plasticity of the different sorting pathways within the endovacuolar system.

description: Kool explains how he came to the work of Holocaust memorialization through his family history as many members from both sides of his family were killed in the Holocaust and he was the child of a survivor. He also reflects on his educational background in moral philosophy which informs his approach to Holocaust education by focusing on the broader cultural context in which violence occurs without necessarily relying on specific and graphic examples of such violence.

Automatic Route Setting and Dynamic Rescheduling Following Disturbance
Creators: name: Mouhiyadin, Said
Publisher: name: National Academic Digital Repository of Ethiopia

description: Nowadays, development cannot be achieved without modern infrastructure capacity. The new railway project which links Addis Ababa to Djibouti aims to fulfill this task through safety and reliability as major goals. Railway operating near their theoretical capacity is particularly vulnerable to disruption by human behavior or engineering failures that lead to delays or to even cancellations of services. In order to prevent such incidents, the interlocking system is set to automatic or semi-automatic mode and rescheduling is planned by the system to set a new route for the remaining trains. This study aimed to analyze how the system reacts and respond to disruptive incidents in minimizing the impact of such disturbance. After reviewing relevant literatures regarding most occurring disruptive incidents in train operation and their consequences on the railway network reliability, we defined train rescheduling operation and more precisely the automatic route selection with their characteristics parameters after a disruption such as an accident on a level crossing or faults in electronics device. We introduce C++ programming language to model route setting using spanning tree configuration. A case study on rescheduling operation on a selected British railway area is carried on to evaluate delays cost after disruption. This data was processed to model how delays relevant to a specific disruption affect trains in a railway network using a neural network with a high performance.
Magnetoresistence engineering and singlet/triplet switching in InAs nanowire quantum dots with ferromagnetic sidegates

description: We present magnetoresistance (MR) experiments on an InAs nanowire quantum dot device with two ferromagnetic sidegates (FSGs) in a split-gate geometry. The wire segment can be electrically tuned to a single dot or to a double dot regime using the FSGs and a backgate. In both regimes we find a strong MR and a sharp MR switching of up to 25\% at the field at which the magnetizations of the FSGs are inverted by the external field. The sign and amplitude of the MR and the MR switching can both be tuned electrically by the FSGs. In a double dot regime close to pinch-off we find {\it two} sharp transitions in the conductance, reminiscent of tunneling MR (TMR) between two ferromagnetic contacts, with one transition near zero and one at the FSG switching fields. These surprisingly rich characteristics we explain in several simple resonant tunneling models. For example, the TMR-like MR can be understood as a stray-field controlled transition between singlet and a triplet double dot states. Such local magnetic fields are the key elements in various proposals to engineer novel states of matter and may be used for testing electron spin-based Bell inequalities.

description: The concept of a supersolid state is paradoxical. It combines the crystallization of a many-body system with dissipationless flow of the atoms it is built of. This quantum phase requires the breaking of two continuous symmetries, the phase invariance of a superfluid and the continuous translational invariance to form the crystal,. Proposed for helium almost 50 years ago, experimental verification of supersolidity remains elusive. A variant with only discrete translational symmetry breaking on a preimposed lattice structure, the `lattice supersolid', has been realized based on self-organization of a Bose-Einstein condensate (BEC). However, lattice supersolids do not feature the continuous ground state degeneracy that characterizes the supersolid state as originally proposed. Here we report the realization of a supersolid with continuous translational symmetry breaking. The continuous symmetry emerges from two discrete spatial ones by symmetrically coupling a BEC to the modes of two optical cavities. We establish the phase coherence of the supersolid and find a high ground-state degeneracy by measuring the crystal position over many realizations through the light fields leaking from the cavities. These light fields are also used to monitor the position fluctuations in real-time. Our concept provides a route to creating and studying glassy many-body systems with contrallably lifted ground-state degeneracies, such as supersolids in the presence of disorder.

description: Menczer explains his family connection to the history as his parents were survivors of a work camp in Bershad. He ended up involved in memorialization work after being introduced to a meeting group for second-generation survivors. His work on Holocaust education and memorializing in Victoria began after he moved there in 2010 where he found there were differing philosophies amongst the groups and people working to memorialize the Holocaust. Ultimately, he and a small team of community members worked to memorialize the Holocaust in a way that acknowledged connection between the persecution of Jewish people and the persecution of other groups of people. Menzcer argues that this approach ensures Jewish people are not depicted solely as victims as he does not want Jewish people to adopt an “us vs. them” view of the world.
