GOITEOM BUGUSA 2021-07-01 Moringa oleifera L. is a flowering tree which belongs to Moringaceae family within the genus of Moringa. This plant is a tropical plant and native to India, Pakistan and Bangladesh. It was introduced to Ethiopia before several years. It is now mostly found in the South part of Ethiopia. Traditionally Moringa were used as a natural medicine. Scientific evidences implicated that the plant can be used as nutrition source. The plant has high mineral content, vitamin and many essential amino acids. All part of the plant is edible except the woody portion. The plant can be propagated through vegetative propagation but, it has poor root system. https://zenodo.org/record/1211 10.20372/nadre:1211 oai:zenodo.org:1211 doi:10.20372/nadre:1210 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by PROTOCOL OPTIMIZATION OF GROWTH REGULATORS FOR IN VITRO PROPAGATION OF Moringa Oleifera L.

MUBAREK JEMAL 2019-05-01 The Ethiopian construction industry has been always criticized for its underperformance due to various reasons. The performance of the construction industry is one of the major development constraints in our country since our development highly depends on the growth of physical infrastructures. Therefore, it is important to identify the factors that are contributing to the underperformance to minimize their effect and consequently improve the industry. Performance measurement is identified as the first stage in any improvement process. It is important for organizations to evaluate their actual objectives against the predefined goals to make certain that they are doing well towards achieving the project goals. Therefore, there is a necessity to develop building project performance evaluation method, which can be easily applied on projects to assess their status at different stages of project lifecycle. In this thesis, it’s attempted to develop multidimensional performance evaluation method which incorporates both leading and lagging KPIs and apply the analytic hierarchy process (AHP) to formulate a benchmarking method to assess project performance at any phase of the construction stage. Five key performance indicators are identified from literatures and experience of other countries, pairwise comparison of each performance indicator is performed using AHP tool. The result of the analysis shows that quality is major performance indicator with 34%, while time, cost, safety and client’s satisfaction have 24%, 13%, 16% and 13% respectively. https://zenodo.org/record/1337 10.20372/nadre:1337 oai:zenodo.org:1337 doi:10.20372/nadre:1336 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by Thesis Submitted to the College of Architecture and Civil Engineering for the Partial Fulfillment of the Requirements for the Degree of Master of Science in Civil Engineering (Construction Technology and Management info:eu-repo/semantics/doctoralThesis publication-thesis

TEWODROS ALI 2019-09-01 Roads that transport people and commodities from one place to another are subjected to heavy loadings and harsh environmental conditions, due to which they deteriorate with time. Therefore, as literatures indicate road performance has to be monitored to evaluate the rate of deterioration, need for maintenance, and proper scheduling of maintenance activities. This research was designed to evaluate Addis Ababa City road network performance and assessing the traditional road maintenance along with the determination the road agency capacity to start to apply Performance Based Road Maintenance. Under the study seven sample road sections were selected based on cluster and purposive sampling technique. Throughout the selected road samples roads a condition survey were conducted using automated pavement condition survey vehicle to evaluate distress severity extent and International Roughness Index (IRI). In order to assess the current method of road maintenance at Addis Ababa City Road Authority and their competency to start Performance Based Road Maintenance an interview and desk study were used. The result for road condition survey indicates minor surface distress and poor riding quality which is characterized with greater than 5 % surface distress and IRI greater than 2.7 mm/m.

DIRIBA YADATA AYANSA 2020-12-01 Achibo-Sombo which is known for its extensive coal deposits is situated in Oromia regional state, South-Western Ethiopian. The present study was focused to analyses the coal bearing sedimentary rock, lithostratigraphy, and quality of coal seam deposit in the Achibo-Sombo Area. The stratigraphy of the area was investigated by integrating borehole data and separating the area section wise based on field survey. The area is characterized by variable lithostratigraphic units: Basement complex, Lower Basalt, Coal bearing sedimentary rock (i.e.., interbedded mudstone and sandstone layers comprising plant fossils with laminated carbonaceous shale, shale, oil shale, and coaly shale) and Upper Basalt to the latest. The presence of Sandstone, Mudstone, Coal Beds and Plant fossils bear fluviatile deposits where as the intercalated various shale layers envisage the lacustrine environment. For this study, fifteen (15) representative samples were taken separately with respect to their seam thickness. Accordingly, coal seam thickness from outcrop ranges (0.45 to 4.8m) and (2.5 to 8.37m) from borehole data and the overall coal seam ranges from (0.45 to 8.37m). The quality of coal at Achibo Sombo was analyzed by Adiabatic Calorie Metter, Gravimetric and Proximate techniques. https://zenodo.org/record/1371 10.20372/nadre:1371 oai:zenodo.org:1371 doi:10.20372/nadre:1370 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by STRATIGRAPHY AND QUALITY ASSESSMENT OF COAL AT ACHIBO DEPARTMENT OF GEOLOGY COLLEGE OF i ACHIBO-SOMBO AREA, SOUTH WESTERN ETHIOPIA info:eu-repo/semantics/doctoralThesis publication-thesis

HAYLEYESUS ANDUALEM ALEMAYEHU 2020-05-01 CubeSat is next generation, promising, and small-sized satellites that can be easily assembled using commercially available components with a low investment cost. Attitude control is one of the core subsystems in the CubeSat system that deals with how to orient the CubeSat in any desired direction. Proper attitude controller of satellite design is necessary since devices that need pointing direction like antennae, camera, and some measurement devices are always mounted on the satellite. Uncontrolled CubeSat may even cause the entire mission loss. Fuzzy controllers and linear quadratic controller are among the commonly employed controllers in CubeSat attitude control. Although manually tuned linear quadratic controller design shows good performance without actuator saturation, it is not optimal in handling the tradeoff between the desired performance and actuator saturation. A genetic algorithm is employed to handle this optimization problem. Besides, developing fuzzy controllers is challenging for multiple inputs and multiple outputs systems using expert knowledge and intuitive rational guess. An adaptive neuro-fuzzy inference system is proposed to develop a fuzzy system using training data sampled from the simulation of a genetically tuned linear quadratic regulator. These fuzzy systems mimic the linear quadratic regulator that is tuned by the genetic algorithm. MATLAB is used for the genetic algorithm optimization of linear quadratic regulator and learning based fuzzy controller design. The attitude kinematics is modeled using quaternion while the dynamics of the CubeSat's attitude considers reaction wheel actuation and gravity gradient torque https://zenodo.org/record/1379 10.20372/nadre:1379 oai:zenodo.org:1379 doi:10.20372/nadre:1378 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by NEURO-FUZZY SYSTEM AND GENETIC ALGORITHM FOR CUBESAT LQR BASED ATTITUDE CONTROL SYSTEM info:eu-repo/semantics/article publication-article

FIREW DEREJE 2019-02-01 In many industrial process and operations heat exchangers are one of the most important thermal devices. Shell and tube heat exchangers are the common types of heat exchangers and sustained a wide range of operating temperature and pressure. Controlling heat exchanger system is a very challenging task due to its nonlinearity. While the amount of flow rates of both manipulated variable and disturbance variable changes, the gain, time delay and time constant varies, hence causing system nonlinearity. The solution for such problems is finding mathematical model that represents the real system and designing suitable controller which remove the offset, making fast settling with minimum steady state error possible. Input data for MATLAB system identification tool was generated experimentally. https://zenodo.org/record/1405 10.20372/nadre:1405 oai:zenodo.org:1405 doi:10.20372/nadre:1404 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by COMPARATIVE STUDY ON THE PERFORMANCES OF PROPORTIONAL INTEGRAL DERIVATIVE (PID) AND MODEL PREDICTIVE CONTROL (MPC) FOR CONTROLLING SHELL AND TUBE HEAT EXCHANGERS info:eu-repo/semantics/doctoralThesis publication-thesis

BELAY MERSHA WOLDEHANA 2018-10-01 Textile and garment industries in Ethiopia are opt as priority sector for the economic as well as industrial development of the country. In realizing this objective, the performances, challenges and prospects of these industries require the attention of its stakeholders. Identifying the export challenges and measuring the export performance level with different performance measures help to resolve the problems of the industry. The prospects of the industries also need due consideration to attract foreign investment to the sector. The overall objective of this research is to assess the export performances, challenges and prospects of Textile and Garment industries in Ethiopia. The research design used for the study was a descriptive research design. The qualitative approach was followed to assess the challenges and prospects of the industry while the quantitative approach used to assess the export performances of the industry. Questioner and interview were used as the primary data collection tools. The major findings of this study indicated that the export performance of the sector during 2012/13 GC to 2016/17 GC was improved by 138.9% from the preceding five years period. The exporting firms’ growth also scored a positive growth (on average 16.5%). However, the result obtained by annual export sales growth (on average negative 1.3%) and export sales to plan ratio (on average 34.5%) indicated that the performances obtained did not reach to the required level. The paradox observed here is the average annual export sales growth with the average exporting firms’ growth. The average export sale to GDP (Gross Domestic Product) ratio (0.26%) shows that the contribution of the export sales of this sector to GDP was insignificant. The main products exported from this sector are garment, fabrics, yarn and cultural cloths. https://zenodo.org/record/1445 10.20372/nadre:1445 oai:zenodo.org:1445 doi:10.20372/nadre:1444 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by AN ASSESSMENT ON EXPORT PERFORMANCES, CHALLENGES AND PROSPECTS OF TEXTILE AND GARMENT INDUSTRIES IN ETHIOPIA info:eu-repo/semantics/doctoralThesis publication-thesis

BIRUHI TESFAYE 2020-12-01 The laboratory test process to determine the California bearing ratio (CBR) of black cotton soils is not only overpriced but also time-consuming as well. Hence advanced prediction of CBR plays a significant role as it is applicable in pavement design. The strength of soil or CBR can be improved using eggshell and waste glass powder when they are mixed with the proper ratio. The prediction of CBR of treated soil was executed by Artificial Neural Networks (ANNs) which is a computational tool based on the properties of the biological neural systems. ANNs have been used over the last few years in the modeling of different parameters. To observe CBR values, combined eggshell and waste glass powder was added to soil as 2% ESP + 2% WGP, 4% ESP + 4% WGP, 6% ESP + 6% WGP, and 8% ESP + 8% WGP of the weights of the soil samples. Accordingly, the necessary tests were conducted in order to get the required best model. From the findings at 4%ESP +4%WGP dosage addition, the minimum LL, PL & PI were obtained as 53.95%, 40%, and 13.95 respectively. https://zenodo.org/record/1763 10.20372/nadre:1763 oai:zenodo.org:1763 doi:10.20372/nadre:1762 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by PREDICTION OF CALIFORNIA BEARING RATIO OF A BLACK COTTON SOIL STABILIZED WITH WASTE GLASS AND EGGSHELL POWDER USING ARTIFICIAL NEURAL NETWORK info:eu-repo/semantics/article publication-article

GEMECHIS ADULA DUGUMA 2019-06-01 Embankments are key elements in the development of structures such as dams and roads in infrastructure. Residual soils are generally used as fills in the construction of embankments in areas where residual soils are the dominant soil types, such as lateritic soil. The characteristics of lateritic soils are that they lose their shear strength under fully saturated conditions and their properties vary from region to region. The chemical composition and the environment influence the property of the soil. In such soils, the binding agent iron oxide changes its composition with time and in the presence of moisture. Failures of lateritic-based embankments have been observed, and found to be safe with a high safety factor. This study is carried out to investigate the stability of embankments with sudden loss of strength when they are completely saturated. https://zenodo.org/record/1769 10.20372/nadre:1769 oai:zenodo.org:1769 doi:10.20372/nadre:1768 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by SLOPE STABILITY ANALYSIS OF LATERITIC SOILS IN CONSTRUCTION OF ROAD EMBANKMENTS (THE CASE OF NEJO-MENDI) info:eu-repo/semantics/doctoralThesis publication-thesis

DANIEL MENGISTU MULETA 2021-07-01 The driveshaft is one of the most commonly failed components in vehicles. Recent studies show that fatigue cracks that initiate in the region of the output splines are the main cause of the failure. This study was mainly aimed at identifying the effects of the spline root fillet radius and the number of teeth on the design modification of the driveshaft. In this regard, the Finite element method was incorporated to analyze the total deformation, the local stress concentration around the critical areas under the static operating conditions, and fatigue behaviors during the operation. Moreover, theoretical calculations were used to evaluate the equivalent (Von-mises) stress and the factor of safety of the driveshaft around the output splines according to ANSI standard. The theoretical calculations of the equivalent stress under the static conditions and the factor of safety were used as a benchmark for the simulations, and the results are in good agreement with each other.

ALEMSEGED MULUGATA 2019-06-01 The power factor correction of electrical loads is a problem common to all industrial companies. So, in order to utilize a stable and efficient energy to every society power must be managed properly. In most power systems, a poor power factor resulting from an increasing use of inductive loads is often overlooked. A power factor correction unit would allow the system to restore its power factor close to unity for economical operation Laundry and Toilet Soap Factory of Star Soap and Detergent Industry Private Limited Company is located in Akaki-Kallitti Subcity, specifically in front of the place commonly called Wuha Limat. It produces soaps and detergents. The machines the factory uses are inductive operating with total power of 668.11 KW at an average lagging power factor of 0.8 without capacitor bank. This project assessed the power consumption of a Laundry and Toilet Soap Factory of Star Soap and Detergent Industry Private Limited Company and computed the apparent power at 0.8 lagging power factor and at the desired 0.95 power factor using information obtained from the name plates of the inductive loads at the factory. The result showed that at full capacity, for the 131.8638-KVA apparent power reduction/hour due to the power factor correction, there could have been a saving of 607, 628. 3904 KVA/year. https://zenodo.org/record/1815 10.20372/nadre:1815 oai:zenodo.org:1815 doi:10.20372/nadre:1814 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by DESIGN AND IMPLEMENTATION OF ARDUINO-BASED AUTOMATIC POWER FACTOR CORRECTION FOR STAR SOAP AND DETERGENT INDUSTRY PRIVATE LIMITED COMPANY info:eu-repo/semantics/doctoralThesis publication-thesis

YIBELTAL AYCHEW BEYENE 2021-01-01 Hot Asphalt Mixtures (HMA) is composite of mineral aggregates, asphalt binder, and air voids. Mineral aggregate is covered about 95 percent of the total mixture. In asphalt pavement production, aggregate gradation is specified in a large percent passing range to use locally available material and to be economical. This large gap of the aggregate gradation specification range alters the performance of the asphalt concrete by change the aggregate surface area. The aggregate surface area has a critical role in the hot mix asphalt performance by altering the coated asphalt film thickness on the aggregate surface and this controls overall mixture properties. Various studies have shown that the variation aggregate surface area has a significant effect on the performance of asphalt concrete pavements by using Marshall Test methods. This study was mainly evaluated the effect of aggregate surface area on the mixture volumetric properties and moisture damage. Different aggregate surface areas were determined in the blending aggregate gradation percent passing specification range by multiplying empirical surface area factor. Using 3.12m2/kg, 4.58m2/kg, 6.19m2/kg, 7.93m2/kg, and 9.64m2/kg aggregate surface areas a number of trial mixes have been prepared using the Marshal Mix design method.

BINIAM ASSEFA 2021-06-01 The major causes of damages of concrete face rockfill dams (CFRD) is displacement of the dam body. Many historical evidences proved that when the settlement of dam crest is greater than 1% of the dam height, cracks on the face slab and openings occur which results in high leakage rate resulting in operation problem of the dam. In addition, several high CFRDs have experienced the cracking of the concrete face during first reservoir impounding. In this study, deformation characteristics of a concrete faced rock-fill dam (CFRD) of the Grand Ethiopian Renaissance dam was investigated. Secondary data was used to model the foundation and embankment materials. Two dimensional plane strain finite element analyses were carried out to assess the displacements in the dam both for construction and impoundment stages by using finite element method (FEM) computer program PLAXIS 2D. The hardening soil model is used to represent the nonlinear, inelastic and stress dependent behavior of rock-fill materials and Hoek-Brown model to simulate the foundation rock and linear elastic model is used to represent the stress-strain behavior of face slab, Plinth, and access gallery. https://zenodo.org/record/1917 10.20372/nadre:1917 oai:zenodo.org:1917 doi:10.20372/nadre:1916 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by NUMERICAL INVESTIGATION ON THE DEFORMATION CHARACTERSTICS OF SADDLE DAM: A CASE OF GRAND ETHIOPIAN RENAISSANCE DAM info:eu-repo/semantics/doctoralThesis publication-thesis

BEWKET DAGNE TEGEGNE 2020-02-01 Unsteady-flow simulation of the dam break is performed using HEC-RAS and results are mapped using the RAS mapping. Inundation mapping of water surface profile, Velocity and depth results from dam failure models and provides a preliminary assessment of the flood hazard and provides insight for emergency preparedness. The Unsteady process is for gathering and preparing data, creating an unsteady-flow model in HEC-RAS, entry of dam breach parameters, performing a dam failure analysis, and mapping of the flood progression. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis and flood mapping. The results show that dam break is a complicated and comprehensive process involving lots of principles. Koga Dam break due to overtopping elongates the time period of high water surface level, which increases the duration of risk. The design Probable Maximum Flood (PMF) is 570 m3/sec statically estimated and PMF also estimated in HEC-HMS model after calibration and validation is 537m3/sec. The calibration result of HEC-HMS model is the Nash-Sutcliffe Efficiency criteria for the calibration N=0.543 coefficient of determination (r2) of 0.7334 daily based. Validation result is the Nash-Sutcliffe Efficiency N=0.6 and coefficient of determination (r2)=0.8.The result of the simulation under overtopping failure showed that the inundated area surrounding Koga River downstream of the dam is about 10.2 km2 with maximum flood depth is 16 m, water surface velocity ranges from 0.00 to 11 m/s. Most of floodplain areas varied from middle to high flood hazard level, and only few areas had very high level of flood hazard especially on river side https://zenodo.org/record/2089 10.20372/nadre:2089 oai:zenodo.org:2089 doi:10.20372/nadre:2088 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by DAM BREACH ANALYSIS AND FLOOD INUNDATION MAPPING THE CASE OF KOGA DAM, ABAY BASIN, ETHIOPIA info:eu-repo/semantics/doctoralThesis publication-thesis

GEBREMICHAEL GEBRU 2020-05-01 In this thesis, researchers have studied the area of virtualization. The focus has been on the sub-area live migration, a technique that allows seamless migration of a virtual machine from one physical machine to another physical machine. Live virtual machine migration refers to the process of moving a running virtual machine or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination. Live virtual machine migration is an attractive technique used to utilize resources in cloud-based data centers through load balancing, fault tolerance, and system maintenance. The performance of live VM migration is measured using different parameters such as total migration time, downtime, and total memory page transferred. This study has proposed a solution to the problem of a huge number of memory pages are being dirtied during the iterative phase of pre-copy live VM migration. A live migration based on combined memory compression and smart termination criteria is proposed it operate as follows: before memory pages are being transferred compression, process is undertaken on those pages. While memory pages are transferred from source host to destination host iteratively, a smart termination criterion is used as a control unit and, when and how the iterative phase of pre-copy will be executed is examined using this controlling system https://zenodo.org/record/2135 10.20372/nadre:2135 oai:zenodo.org:2135 doi:10.20372/nadre:2134 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by LIVE VIRTUAL MACHINE MIGARTION BASED ON MEMORY COMPRESSION AND SMART TERMINATION CRITERIA info:eu-repo/semantics/doctoralThesis publication-thesis

EYUOEL FRANCO 2020-10-01 Flood is an overflowing of water over land surface when the volume of water raises higher than the banks of the water body. Ethiopia is one of the east African countries that is severely affected by it due to the countries rainfall characteristics in which, more than 80% of its annual precipitation falls in four wet month. The objective of this research was to model the flow characteristics of Gilgel-Abay River and to develop flood map for the area. Integration of HEC-HMS and HEC-RAS with ARC-GIS was used to create a regional model for floodplain determination, modeling analysis representation. HEC-HMS was used for hydrologic model calibration with the use of daily time series data for return periods of 2, 10, 25, 50 and 100 years and the model was compared with different frequency analysis methods. HEC-RAS with HEC-GEORAS interface in coordination with ARC-GIS was used to carry out the two dimensional hydraulic modeling and generation of flood maps. Daily discharge and rainfall data were used for HEC-HMS Calibration and Validation with both results showing good match between measured and simulated precipitation data, with acceptable range of coefficient of determination R2 (between 0.7 and 1, Calibration value being 0.72 and Validation 0.73) and Nash-Sutcliffe (NSE) (between 0.5 and 0.75, Calibration value being 0.51 and Validation 0.54). The result of hydrologic model demonstrated peak discharges of 223.9 m3/s, 367.5 m3/s, 438.4 m3/s, 440.5 m3/s and 501.6m3/s for return periods of 2, 10, 25, 50 and 100 years respectively https://zenodo.org/record/2147 10.20372/nadre:2147 oai:zenodo.org:2147 doi:10.20372/nadre:2146 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by FLOODPLAIN INUNDATION MODELING AND MAPPING FOR GILGEL ABAY RIVER: NILE BASIN, ETHIOPIA info:eu-repo/semantics/doctoralThesis publication-thesis

ZEBREHE GUESH FISHA 2019-06-01 Sesame is a strategically important crop to Ethiopia, as it ranks as a top exportable crop and plays a great role in the country’s economy. In the last few years (2007-2011), Ethiopia was the world's 3rd largest sesame exporter, supplying to China and Turkey, however, sesame production has been declining, though; there is still high potential for increased production. This is because of the shortage of professionals to diagnosis and controls the sesame diseases at the right time. So it is important to develop an expert system that helps the professionals as well as for the investors, farmers, and Ethiopians as a whole by diagnosis and giving advisory for the sesame diseases. The objective of this study is to develop a web Based self-learning expert system for Diagnosing and Advisory of Sesame diseases. To develop for the prototype, the knowledge was acquired using both structured and unstructured interviews from selected sample domain experts and represented by production rule, and the Decision tree was used for modeling the knowledge of the sesame diseases and symptoms. https://zenodo.org/record/2163 10.20372/nadre:2163 oai:zenodo.org:2163 doi:10.20372/nadre:2162 url:https://nadre.ethernet.edu.et/communities/aastu url:https://nadre.ethernet.edu.et/communities/zenodo info:eu-repo/semantics/openAccess http://www.opendefinition.org/licenses/cc-by DEVELOPING WEB BASED SELF-LEARNING EXPERT SYSTEM FOR DIAGONOSTIC ADVISORY OF SESAME DISEASES IN ETHIOPIA info:eu-repo/semantics/article publication-article
