Creators: name: G/Selassie, Kidanu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: the reduction process of hexavalent chromium from electroplating wastewater by chemical precipitation in order to achieve the maximum trivalent chromium concentration. Sodium bisulphite is one of the widely used coagulants in waste water treatment process and has good reducing ability. Because of its reducing capacity, sodium bisulphite is applied to reduce hexavalent chromium from electroplating wastewater. The study has been conducted in four phases. In phase one reduction of hexavalent chromium, phase two determination of hexavalent chromium, phase three precipitation of chromium sulphate followed by oxidation of the sludge of Chromium (III) hydroxide. Phase one study was carried out to analyze the reduction process of the toxic soluble hexavalent chromium by using the concept of design experiment to justify the number of affecting factors and levels during the laboratory work followed by the synthetic waste sample preparation at Homicho Ammunition Engineering Industry in Ambo. Different experiments were considered like classical method of analysis to quantify and qualify the wastewater sample, atomic absorption spectrophotometric technique was utilized to determine the amount of total chromium, and finally colorimetric method to determine the amount of hexavalent chromium with a suitable complexing agent to engulf the ionic hexavalent Chromium. The total numbers of experiments were fifty four (54), the first twenty seven (27) run was analyzed by labeling the distributed parameters in each beaker of the solution and the number of factors with their levels were indicated. For the purpose of optimization of the selected parameters experiments were replicated, then at the second round of the experiment run number 44 was the optimized one. In order to perform these activities, the concentration of the stock solution was 100 mg/L, and 50 ml of volume was taken to each 500 ml beaker volume with concentration of 10 mg/L. With this amount phase two was conducted, to solidify the solution containing chromium sulphate Cr2 (SO4)3 generated from the redox reaction. . The required reduction time to reach equilibrium, the effectiveness of pH value for Cr (VI) reduction and the required amount of sodium bisulphite to complete reduction were investigated. The redox reaction was completed within 40 minutes, at pH of 2 and 50 mg/L of hexavalent chromium was reacted with 200 mg/L of sodium bisulphite in deionized water. Sodium hydroxide was used to precipitate the solution after the reaction of the precipitating agent and hexavalent chromium. In Final phase oxidation of Chromium (III) hydroxide to hexavalent chromium was carried out; Key words: Cr (VI) reduction, Sodium bisulphite, wastewater treatment

description: Email classification is still a mostly manual task. Consequently, most Web mail users never define a single folder. Recently however, automatic classification offering the same categories to all users has started to appear in some Web mail clients, such as AOL or Gmail. We adopt this approach, rather than previous (unsuccessful) personalized approaches because of the change in the nature of consumer email traffic, which is now dominated by (non-spam) machine-generated email. We propose here a novel approach for (1) automatically distinguishing between personal and machine-generated email and (2) classifying messages into latent categories, without requiring users to have defined any folder. We report how we have discovered that a set of 6 "latent" categories (one for human- and the others for machine-generated messages) can explain a significant portion of email traffic. We describe in details the steps involved in building a Web-scale email categorization system, from the collection of ground-truth labels, the selection of features to the training of models. Experimental evaluation was performed on more than 500 billion messages received during a period of six months by users of Yahoo mail service, who elected to be part of such research studies. Our system achieved precision and recall rates close to 90% and the latent categories we discovered were shown to cover 70% of both email traffic and email search queries. We believe that these results pave the way for a change of approach in the Web mail industry, and could support the invention of new large-scale email discovery paradigms that had not been possible before.

Analytical Methods to Estimate Railway Capacity A Case study to apply on the Addis Ababa Light Rail Transit Project (AA -LRT)
Creators: name: Amanuel, Abreham
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Public mass transportation systems have become an important part of major economic activities in developing cities. The initial high construction cost of urban rail transportation calls for the efficient utilization of the existing infrastructure and estimation of its maximum capacity. A reliable estimation of railway capacity is a basic condition for allocation of railway resources and has a vital importance in evaluation of existing railway infrastructure. Therefore, it is necessary to develop procedures that reliably estimate the railway capacity using data typically available to planners. This thesis studies method that can be applicable in both planning and detailed design stage in Ethiopian condition depending on the available data .An overview concept of railway capacity and the main parameters affecting railway capacity are presented. A simulation method is a widely used technique in railway planning and operation to generate realistic estimates. Analytical methods of estimation railway capacity provide firsthand information about the capacity at early planning stage when most of the factors shaping up the railway capacity are not known and has also provide a reliable result in detailed design stage when it is applied to a simple rail network system like AALRT. In the detailed design report of AALRT, the procedure used in determination of the capacity is not described and only the output results are provided. Therefore, developed methodologies to analyze, improve and control railway capacity utilization are needed for Ethiopian condition. This thesis presents how to determine the number of trains required for a given passenger volume and headway using analytical method and mainly focuses on methods to calculate the main parameters affecting the capacity of Light rail transit system. Methodologies that describe the procedures to follow in estimation and analysis of railway capacity are developed. Two approaches of estimating railway capacity are presented. The first approach is an economical way of estimating railway capacity based on peak hour passenger volume and the second approach is the estimation of achievable capacity using the maximum throughput of the railway line. The combinations of the two approaches enable planners or designers to estimate the capacity of railway at different values of headway and train controlling systems. Using these two approaches, the proposed capacity of AALRT is evaluated and its maximum achievable capacity is estimated. The computational results at the end shows that the proposed headway of AALRT can be improved by reducing total round trip time of the trains and the proposed excess number of trains can be used to reduce the headway of the operation.

description: En este trabajo se estudia la responsabilidad de protección estatal frente al Macrocaso 08 de la JEP. Para esto se extractó el material discursivo en una investigación mixta: cualitativa y cuantitativa, teniendo en cuenta cifras dadas por los ex comandantes ex paramilitares y otros actores del conflicto armado. Es de tipo descriptiva porque se utilizan tanto los informes descritos y expuestos en las audiencias que ofrecen datos interesantes acerca de las Convivir creadas, los políticos, los militares, los paramilitares, los particulares y las empresas que se beneficiaron de las conductas implicadas en el macrocaso 8, como los análisis de la JEP que incorporan información de los procesos en la justicia ordinaria, de Justicia y Paz (ley 975 de 2005) e informes de las diferentes organizaciones. Con base en todo lo anterior se concluye, de una parte que hubo responsabilidad estatal por faltar al deber de proteger a la población y además obrar en su contra. De otra parte, se colige que los análisis de contexto de la JEP que condujeron a la elaboración de patrones de conducta delictiva estatal, representan una ruptura muy importante en una tradición jurídico-política que siempre las atribuyó a conductas aisladas de agentes del Estado.
description: In this wok, the responsibility for state protection against Macrocase 08 of the JEP is studied. For this, the discursive material was extracted in a mixed investigation: qualitative and quantitative, taking into account figures given by former ex-paramilitary commanders and other actors in the armed conflict. It is descriptive in nature because both the reports described and presented in the hearings are used, offering interesting data about the Convivir created, the politicians, the military, the paramilitaries, the individuals and the companies that benefited from the behaviors involved in the macrocase. 8, such as the JEP analyzes that incorporate information from the processes in the ordinary justice system, Justice and Peace (law 975 of 2005) and reports from the different organizations. Based on all of the above, it is concluded, on the one hand, that there was state responsibility for failing to comply with the duty to protect the population and also acting against them. On the other hand, it can be concluded that the context analyzes of the JEP that led to the elaboration of patterns of state criminal behavior represent a very important break in a legal-political tradition that always attributed them to isolated behaviors of State agents.

description: The origin of carbon-enhanced metal-poor (CEMP) stars plays a key role in characterising the formation and evolution of the first stars and the Galaxy since the extremely-poor (EMP) stars with [Fe/H] \leq -2.5 share the common features of carbon enhancement in their surface chemical compositions. The origin of these stars is not yet established due to the controversy of the origin of CEMP stars without the enhancement of s-process element abundances, i.e., so called CEMP-no stars. In this paper, we elaborate the s-process nucleosynthesis in the EMP AGB stars and explore the origin of CEMP stars. We find that the efficiency of the s-process is controlled by O rather than Fe at [Fe/H] \lesssim -2. We demonstrate that the relative abundances of Sr, Ba, Pb to C are explained in terms of the wind accretion from AGB stars in binary systems.

description: The flow of dense suspensions, glasses, and granular materials is heavily influenced by frictional interactions between constituent particles. However, neither hydrodynamics nor friction has successfully explained the full range of flow phenomena in concentrated suspensions. Particles with asperities represent a case in point. Lubrication hydrodynamics fail to completely capture two key rheological properties - namely, that the viscosity increases drastically and the first normal stress difference can switch signs as volume fraction increases. Yet, simulations that account for interparticle friction are also unable to fully predict these properties. Furthermore, experiments show that rheological behavior can vary depending on particle roughness and deformability. We seek to resolve these apparent contradictions by systematically tuning the roughness of model colloids, investigating their viscosity and first normal stress differences under steady shear, and finally generating a rheological state diagram that demonstrates how surface roughness influences the transition between shear thickening and dilatancy. Our simulations, which are in good agreement with the experiments, suggest that friction between rough particles is significant. In addition, we find that roughness progressively lowers the critical conditions required for the onset of shear thickening and dilatancy. Our results thus provides a major contribution in the field of suspension rheology with broad relevance to granular and particulate materials. For instance, particle geometry can be tuned to increase the efficacy of materials that turn solid-like on the application of stimuli. On the other hand, engineers who work with concentrated slurries can now use images of the constituent particles to estimate optimal flow processing conditions.

description: We discuss dynamical systems approaches and methods applied to flat Robertson-Walker models in $f(R)$-gravity. We argue that a complete description of the solution space of a model requires a global state space analysis that motivates globally covering state space adapted variables. This is shown explicitly by an illustrative example, $f(R) = R + αR^2$, $α> 0$, for which we introduce new regular dynamical systems on global compactly extended state spaces for the Jordan and Einstein frames. This example also allows us to illustrate several local and global dynamical systems techniques involving, e.g., blow ups of nilpotent fixed points, center manifold analysis, averaging, and use of monotone functions. As a result of applying dynamical systems methods to globally state space adapted dynamical systems formulations, we obtain pictures of the entire solution spaces in both the Jordan and the Einstein frames. This shows, e.g., that due to the domain of the conformal transformation between the Jordan and Einstein frames, not all the solutions in the Jordan frame are completely contained in the Einstein frame. We also make comparisons with previous dynamical systems approaches to $f(R)$ cosmology and discuss their advantages and disadvantages.

Water Treatment Plant Performance Evaluation Using Turbidity As A Parameter
Creators: name: Enkossa, Misganu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Gafarsa and Lagadadi Water treatment plants play a vital role in supplying drinking water to Addis Ababa City since about 55 years. The two WTPs are located on opposite direction of the city. Groundwater sources developed at the southwest direction of the city augments the waters sources from the two treatment plants. This study focused on evaluation of performance efficiency of the two water treatment plants in view of turbidity removal. The evaluation was conducted by collecting primary turbidity data of water sample at outlet of clarifiers and filters where turbidity of water is removed. During rainy season due to high turbidity of raw water from the impounding reservoirs, daily production of the plants decrease as the surface loading rate is minimized to maintain the required water quality. Magnitude of floc carryover also increases during the wet periods. Lagadadi treatment plant is constructed in two stages. The second stage clarifiers are equipped with tube settlers while the first stage clarifiers have no any type of settlers installed. As observed from the turbidity removal efficiency evaluation of the two stages filters, the second stage filters are more efficient than that of the first stages. The study result revealed that turbidity removal efficiency of Lagadadi treatment plant filters is better than that of Gafarsa. The average turbidity removal efficiency of Gafarsa and Lagadadi filters are 53.13% and 88.45% respectively. For improving rainy season output of the water treatment plants, this study recommended construction of bank filtration adjacent to intake from the impounding reservoirs which reduces turbidity of the raw water by half. Non-uniformity is observed in orifice type weir of the two treatment plant clarifiers, which could be the most probable reason for floc carryover. For minimizing floc carryover, it is recommended to regularly clean the orifices inner surface to maintain uniformity of the cross sectional area which in turn regulate the flow velocity stabilizing the suspended flocs to settle.

description: In the probe limit, we investigate the nonlinear electrodynamical effects of the both exponential form and the logarithmic form on the holographic paramagnetism-ferromagnetism phase transition in the background of a Schwarzschild-AdS black hole spacetime. Moreover, by comparing the exponential form of nonlinear electrodynamics with the logarithmic form of nonlinear electrodynamics and the Born-Infeld nonlinear electrodynamics which has been presented in Ref.~\cite{Wu:2016uyj}, we find that the higher nonlinear electrodynamics correction makes the critical temperature smaller and the magnetic moment harder form in the case without external field. Furthermore, the increase of nonlinear parameter b will result in extending the period of the external magnetic field. Especially, the effect of the exponential form of nonlinear electrodynamics on the periodicity of hysteresis loop is more noticeable.

Design and Simulation of Traction Power Supply System: Case study of Modjo~Hawassa line
Creators: name: Asegid, Belay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: For more than a decade, the railway has experienced a renaissance in many countries after several years of decay. The main reasons for the renewed interest in the railway are environmental, economical, and safety related. This has quite naturally, in turn, increased the interest in railway associated research. Both passenger and freight transports on railway are increasing. In order to cope with this increase, large railway infrastructure investments are expected. An important part of this infrastructure is the railway power supply system – without it, only the weaker and less energy efficient steam and diesel locomotives could be used. This thesis work presents the design and simulation of traction power supply system for the case of Modjo~Hawassa railway line. For this purpose, all the necessary electrical parameters data are collected through literature survey and the traction power supply system major components such as traction substation transformer, autotransformer, the catenary system and the loads are designed. In connection with this, a model that represents the designed components of the power supply system using an existing blocks in the MATLAB/Simulink library were built and integrated into a system called a traction power supply system, which has a total length of 64 kilometer including 60 kilometer single track and 4 kilometer double track railway line and simulated using MATLAB/Simulink environment. Accordingly, the simulation result of the traction power supply system for the three cascaded train which is found at a distance of 64 kilometers from the traction substation reveals that a train voltage of 19.81 kV and current of 414.63 A, a rail voltage of 87.12 V and autotransformer voltage of 19.82 kV in worst case scenario. In addition, the maximum percentage voltage regulation is found to be 26.45 %. As the result, it was found that the voltages and the currents waveform are according to BS EN 50163:2004, EN 50388:2012 and BS EN 50122-1 (IEC 62128-1) standard limits. This shows the performance of designed traction power supply system is within the industry standard.

description: Reproductive manipulation by endosymbiotic Wolbachia can cause unequal inheritance, allowing the manipulator to spread and potentially impacting evolutionary dynamics in infected hosts. Tramp and invasive species are excellent models to study the dynamics of host-Wolbachia associations because introduced populations often diverge in their microbiomes after colonizing new habitats, resulting in infection polymorphisms between native and introduced populations. Ants are the most abundant group of insects on earth, and numerous ant species are classified as highly invasive. However, little is known about the role of Wolbachia in these ecologically dominant insects. Here, we provide the first description of reproductive manipulation by Wolbachia in an ant. We show that Old and New World populations of the cosmotropic tramp ant Cardiocondyla obscurior harbor distinct Wolbachia strains, and that only the Old World strain manipulates host reproduction by causing cytoplasmic incompatibility (CI) in hybrid crosses. By uncovering a symbiont-induced mechanism of reproductive isolation in a social insect, our study provides a novel perspective on the biology of tramp ants and introduces a new system for studying the evolutionary consequences of CI.

Year: 2016

description: Used lubricating oil has been the subject of much debate over recent years in Ethiopia. The amount of lubricating oils disposed annually in the country is considerably large. This amount of waste lubricating oil has a significant impact on both economic and environmental aspects. In this research Acid-clay technology has been tested for re-refining used lubricating oils, usually Total Rubia Tir 7400 15W-40 and Total Quartz 5000 20W-50 by varying acid ratio between 10-20% and adsorbent ratio between 15- 25%. The result showed that the efficiency of the recycling operation depends on these two reagent ratios. Increasing the acid concentration showed a significant difference over the yield, kinematic viscosity and other physicochemical properties, however increasing the amount of acid over the optimum point made no significant change. Better bleaching and yield and other physicochemical properties were achieved with increasing adsorbent ratio. A maximum yield of 71.45% was obtained for Rubia Tir 7400 15W-40 at acid ratio of 15% and 25% adsorbent. Whereas a minimum yield is obtained 42.6% at acid ratio of 10% and 15% adsorbent ratio. For Quartz 5000-20W-50 a maximum and minimum yield, and other physicochemical properties were obtained at 15:25 and 10:15 acid adsorbent ratio respectively with72.5% and 49% yield. All metal contaminants are substantially removed; total base number is enhanced while carbon residue is significantly reduced for both lubricants suggesting the method works effectively regardless of the lubricant type.

description: Genetic risk prediction is an important component of individualized medicine, but prediction accuracies remain low for many complex diseases. A fundamental limitation is the sample sizes of the studies on which the prediction algorithms are trained. One way to increase the effective sample size is to integrate information from previously existing studies. However, it can be difficult to find existing data that examine the target disease of interest, especially if that disease is rare or poorly studied. Furthermore, individual-level genotype data from these auxiliary studies are typically difficult to obtain. This paper proposes a new approach to integrative genetic risk prediction of complex diseases with binary phenotypes. It accommodates possible heterogeneity in the genetic etiologies of the target and auxiliary diseases using a tuning parameter-free nonparametric empirical Bayes procedure, and can be trained using only auxiliary summary statistics. Simulation studies show that the proposed method can provide superior predictive accuracy relative to non-integrative as well as integrative classifiers. The method is applied to a recent study of pediatric autoimmune diseases, where it substantially reduces prediction error for certain target/auxiliary disease combinations. The proposed method is implemented in the R package ssa.

description: The magnetic order induced by the pressure was studied in single crystalline FeSe by means of muon-spin rotation ($μ$SR) technique. By following the evolution of the oscillatory part of the $μ$SR signal as a function of angle between the initial muon-spin polarization and 101 axis of studied crystal it was found that the pressure induced magnetic order in FeSe corresponds either to the collinear (single-stripe) antiferromagnetic order as observed in parent compounds of various FeAs-based superconductors or to the Bi-Collinear order as obtained in FeTe system, but with the Fe spins turned by 45$^{\rm o}$. The value of the magnetic moment per Fe atom was estimated to be $\simeq 0.13-0.14$~$μ_{\rm B}$ at $p\simeq 1.9$~GPa.

description: We propose a new generalization of the Yang-Baxter equation, where the R-matrix depends on cluster $y$-variables in addition to the spectral parameters. We point out that we can construct solutions to this new equation from the recently-found correspondence between Yang-Baxter equations and supersymmetric gauge theories. The $S^2$ partition function of a certain 2d $\mathcal{N}=(2,2)$ quiver gauge theory gives an R-matrix, whereas its FI parameters can be identified with the cluster $y$-variables.

description: Na historiografia dos cemitérios, quando comparadas com os homens, as mulheres – embora sempre presentes na forma como têm sido retratadas – foram frequentemente invisibilizadas quanto ao papel social que neles tiveram. Esta pesquisa procurou evidenciar os papéis femininos no que concerne à materialidade dos cemitérios em contexto urbano contemporâneo. O caso de estudo incidiu o Cemitério Municipal de Loures (inserido na Área Metropolitana de Lisboa), onde se encontram sepultadas destacadas figuras masculinas locais. A propósito da capela nele presente salienta-se o importante, mas quase esquecido, serviço prestado pelas mulheres na passagem dos rituais fúnebres do lugar privado da residência para o espaço público do cemitério.

description: The structural design of railway vehicle bodies depends on the loads they are subject to and the Characteristics of the materials they are manufactured from. In this study structure analysis of Addis Ababa city tram passenger car made of the exact steel material and aluminum honeycomb material are analyzed. Finite element method is used to assess the static structure behavior of the tram car by ANSYS 14.5 software. For 3D modeling used solidwork11 and to simplify the core material selection process and to design the layers for aluminum honeycomb material by ANSYS Composite Prep Post (ACP). The result of the finite element analysis (FEA) shows that the structural analysis of the tram car using Aluminum Honeycomb reduce the gross weight by 12.14% with almost the same maximum principal stress and also its stress and deformation result of tensile, compression, lateral and vertical loading condition result validated against Structural requirements of railway vehicle bodies stated under EN 12663 and EN 15227 standard. The finite element result value of aluminum honeycomb and steel maximum principal stress of minimum variation but due to compression load applied on tram car using Aluminum Honeycomb higher compare to steel material to reduce the variation multi- material approach used to further reduce the stress and the deflection.

Unravelling the physical meaning of the Jaffe-Manohar decomposition of the nucleon spin

description: A general consensus now is that there are two physically inequivalent complete decompositions of the nucleon spin, i.e. the decomposition of the canonical type and that of mechanical type. The well-known Jaffe-Manohar decomposition is of the former type. Unfortunately, there is a wide-spread misbelief that this decomposition matches the partonic picture, which states that motion of quarks in the nucleon is approximately free. In the present monograph, we reveal that this understanding is not necessarily correct and that the Jaffe-Manohar decomposition is not such a decomposition, which natively reflects the intrinsic (or static) orbital angular momentum structure of the nucleon.

description: Recently, machine learning has emerged as an alternative, powerful approach for predicting quantum-mechanical properties of molecules and solids. Here, using kernel ridge regression and atomic fingerprints representing local environments of atoms, we trained a machine-learning model on a crystalline silicon system in order to directly predict the atomic forces at a wide range of temperatures. Our idea is to construct a machine-learning model using a quantum-mechanical data set taken from canonical-ensemble simulations at a higher temperature, or an upper bound of the temperature range. With our model, the force prediction errors were about 2% or smaller with respect to the corresponding force ranges, in the temperature region between 300 and 1650 K. We also verified the applicability to a larger system, ensuring the transferability with respect to system size.
