DESIGN OPTIMISATION OF CONVERGENT-DIVERGENT AIRCRAFT NOZZLE[ ]


The challenges of convergent-divergent nozzle to be used in aero gas turbines have been a bottleneck for research. This paper is therefore geared towards proffering solutions in this respect. The study is carried out using computer based CFD Ansys Fluent simulation code with reference to Solidworks CAD tool for modeling. Analyzed results from study indicate 2.342×108Nm-2 of total pressure against 4.176×108Nm-2 of dynamic pressure of the designed model for the research. Reduction in this performance is observed as the fluid leaves the throat section and proceeds to the divergent region of the nozzle. This attests distribution of pressure in the nozzle as flow accelerates subsonically or supersonically with reduction in pressure drop. Also, turbulence intensity at the nozzle exit is estimated to be 14.7749% as vortex flow is created in the model. Meanwhile, as flow gets stabilized, the turbulence intensity reduces gradually to 0.0026%. This reduction and low turbulence intensity is in line with a laboratory test result in the literature. Consequently, low efficiency production on the part of convergent-divergent nozzle from study is identified as shock wave formation in the divergent portion of the model. The study confirms that CFD simulation code and Solidworks are effective predictive and prognostic engineering softwares capable of modelling, simulating and analysing thermo-fluid characteristics and hence convergent-divergent aircraft nozzle.

Comparative Analysis of Buckling Behaviour of Cylindrical Shells Reinforced with Inclined Stiffeners and that Reinforced with Rings-and-Stringers under Uniform Bending[ ]


This research presents comparative analysis of buckling behaviour of cylindrical shells reinforced with inclined stiffeners and that reinforced with rings-and-stringers under Uniform Bending. The method of solution was carried out by the use of nonlinear large deflection theory and the effect of initial imperfections in the strain-displacement equations was considered. The Ritz method was used to determine the buckling stress parameter of the shell. Numerical examples were carried by varying the angle of inclination of the stiffeners at different imperfect ratios with other properties like: flexural rigidity and torsional rigidity of the stiffeners, deflection parameters, internal pressure and radius of curvature of the shell being kept constant. The results shows that the worst critical buckling stress of internally pressurized thin cylindrical shell considered in this research occurs when the stiffeners are inclined at 450 at imperfect ratio of 0.1 While, the maximum buckling stress occurs when the stiffeners are inclined at 100 at imperfect ratio of 0.5 .Also, the buckling stress for the cylinders reinforced with rings-and-stringers considered in this work are averagely greater than those reinforced with stiffeners inclined at 450, but less than those reinforced with stiffeners inclined at 100, 200, 300, 500 and 600 respectively. Thus, rings-and-stringers are more effective than inclined stiffeners at 450, but less effective than stiffeners inclined at 100, 200, 300, 500 and 600 respectively.

Relationship between Ralstonia solanacearum and bioagents recovered from different habitats[ ]


Bacterial wilt caused by Ralstonia solanacearum phylotype II sequevar I (race 3 biovar 2), is considered one of the most destructive bacterial diseases of potato plants. The aim of this study was to evaluate the potential of some bacterial antagonists on suppressing the causative bacterium. In this regard, 420 isolates of R.solanacearum were risolated from different habitats at different Egyptian districts. The variation among these isolates was assessed on the basis of their pathogenic potentialities to tomato seedlings in the greenhouse. The highest potential, as shown by the wilt severity, was obtained by 11 out of 420 isolates. The most aggressiveness isolates were identified by accurate techniques. A collection of 318 isolates of rhizobacteria from rhizosphere of different plants were tested to lay out a biological control protocol against R.solanacearum selected strains. In vitro, 14 bacterial isolates were more effective in suppressing the pathogen at different levels of relative power of antibiosis. These isolates were categorized into three groups according to their gram-staining reaction, cell morphology and cultural characteristics. Further evaluation under the greenhouse condition has shown that six of the antagonistic isolates were effective in suppressing disease development, as expressed by the Area Under Disease Progress Curve (AUDPC). These isolates were identified as: Streptomyces toxytricini, Stenotrophomonas maltophilia, Bacillus pseudomycoides and Brevibacillus brevis.

ModalAnalysis of optimization techniques of adhesively bonded Aluminum and CFRPComposites[ ]


Adhesive bonding is preferred joining technique over welding and mechanical fastening method because of its light weight and high strength characteristics. In aerospace applications, adhesive bonding is highly incorporated in FMLs (Fiber Metal Laminate). These FMLs usually fails under peel and shear stresses. In this research work, Adhesive lap joint between aluminum and CFRP is optimized through two different joint designs to find out the most effective and suitable joint design to avoid shear and peel stresses and hence to reduce the failure of adhesively bonded parts. Carbon fiber and aluminum are the structural component in most of the aircraft applications. So in this research project adhesive bonding between CFRP/Aluminum is optimized by two methods i.e. introduction of fillets and introduction of step configuration in standard lap joint configuration. Modal analysis in Ansys workbench is carried out to find out the most effective technique among the two proposed configurations that reduces the shear and peel stresses and hence minimizes the failures

Investigation of the Damping Ratio and Shear Modulus of Soil along Light Rail Transit Route in Megenagna-Hayat Road[ ]


Soil vibration may also cause by the movement of heavy vehicles and train, which affect adjacent structures along the route. The response of soils for incoming vibration from the train is measured by the dynamic properties of soils such as shear modulus and damping ratio. These soil parameters are very significant to study the ground motion as well as the site response of soil deposits under cyclic loading and soil-structure interaction. About this, the research study has been sought to give some information about the condition, specifically the shear modulus and damping ratio of the soil along the Addis Ababa light rail transit route from Megenagna to Hayat road. Also, this study was dealt with soil distribution along the route, which was conducted to determine soil properties. The sand replacement method was also utilized to investigate the controlling factors for the dynamic soil properties. From related literature, it was known that the dynamic soil properties are influenced by soil types and location of the soil profile.

An Enhanced Approach for Web Services Clustering using Supervised Machine Learning Techniques[ ]


Automatic document classification provides techniques that may improve and support web service clustering. As the number of services increases, the cost of classifying services through manual work increases. In this research, we presented an enhanced approach for service clustering that combines text mining and machine learning technology. The method only uses text description of each service so that it can classify different types of services, such as WSDL Web Service, RESTful Web Service. This approach provides better performance in terms of service discovery efficiency and effectiveness. In this paper, we introduced new features, named referenced ontology, that can be extracted from WSDL documents and integrated to other features to get better classification accuracy. This paper proposes a text mining approach to automatically classify services to specific domains and identify key concepts inside service textual documentation. This approach is validated on a dataset of 1088 web services categorized into 9 fields yielding accuracy up to 91 %. Our approach utilizes the supervised machine learning techniques such as Decision Trees, Naïve Bays, and Deep Learning classification methods. A comparison between these techniques are made regarding the result accuracy and the computation cost.

The Power of Website and People’s Tendency towards the Paradigm Shift: The Case of Jimma University, Ethiopia[ ]


By the time of drafting this article, it was surprising to learn that the World Wide Web (“WWW’or simply the “web”) is only 10158 days old. Given the wide spread influence of this technology, one would make such a naïve presumption about website as a century old phenomenon, at least before the observation. The internet, and ultimately the evolution of websites brought tremendous development to human life around the world in almost all aspects of endeavour such us content delivery, lead capture, and direct selling. The question is however, how quickly people are adapting to this technology to get their presence felt around the world at ease. In Jimma University, for instance, it’s hard to find a wide spread use of website attributed to limited understanding of the power of this technology, less tendency for the paradigm shift, limited trust of information on websites, complicated web structure that the organization owns and the likes.

To Study the Self-Sabotaging Etiquette in concordance with Criminality[ ]


Self- sabotage or to vandalize oneself is the inimical behavior in the young. Risk factors amalgamate to precipitate and perpetuate these problems. There is an unswerving consanguinity amidst causes and outcomes. Rather, the cause is usually a combination of predisposing constitutional factors, arising from multitudinal sources or aboriginal experience and expediting stressful events. These etiological factors act through- biochemical, psychological and social process to outturn the causatum. This further cossets into the victimology of the self-saboteurs and also focuses on the issues of their contrived anti-social acts.Self- sabotage or to vandalize oneself is the inimical behavior in the young.

Improvement of Re-order Point Resupplying Method of a Fluctuating Productive System[ ]


The aim of stock optimization is insuring the supply of production system without breaking, with saving a minimum stock level. Several methods of resupplying, classics and other developed are proposed to reach this objective. Most of the various production systems follow the re-order point resupplying method, because of its economic properties and its flexibility. But, various constraints influence the production systems, provoking from time to time a desynchronization between the stock level and the effective needs. This desynchronization expressed by leading breaks of stock in case of raise rate production and surplus in case of production rhythm decrease. The envisaged research allows improving this method (re-order point resupplying) to avoid these last two problems. A new proposed approach considers the value of the re-order point resupplying as a variable dependent on the production rhythm (Cmean)i, at every immediate period between the receipting moment of the last command (tr)i-1 and the current moment (ti),by preserving the same principle of resupplyingThe aim of stock optimization is insuring the supply of production system without breaking, with saving a minimum stock level.

Securing Data Storage System for Internet of Things Using Key Aggregate Cryptosystem[ ]


In the most recent couple of decade, the thought of connecting existing computing devices has brought forth a new concept called “connecting things”. Due to the advances in data collection technology in sensors, such as embedded devices, ubiquitous and RFID technology has led large number of gadgets connected in network which are consistently transmitting their data over the time. This data obtained is very precious to many enterprises, so there is need of secure mass storage system for this data. To make the transmission and storage of data more secure, data is encrypted before storing. In the proposed system the data obtained from the IoT network is divided into blocks based on the default threshold, so that it is more reliable and secure. The blocks are then encrypted using the Key Aggregate Cryptosystem (KAC). Using the KAC scheme the data is encrypted with a public key and a ciphertext class after it is divided into blocks. An aggregate key is generated for set of blocks which is used in decryption.In the most recent couple of decade, the thought of connecting existing computing devices has brought forth a new concept called “connecting things”. Due to the advances in data collection technology in sensors, such as embedded devices, ubiquitous and RFID technology has led large number of gadgets connected in network which are consistently transmitting their data over the time. This data obtained is very precious to many enterprises, so there is need of secure mass storage system for this data. To make the transmission and storage of data more secure, data is encrypted before storing. In the proposed system the data obtained from the IoT network is divided into blocks based on the default threshold, so that it is more reliable and secure. The blocks are then encrypted using the Key Aggregate Cryptosystem (KAC). Using the KAC scheme the data is encrypted with a public key and a ciphertext class after it is divided into blocks. An aggregate key is generated for set of blocks which is used in decryption.

Secure Sharing & Data Deduplication over Cloud: A Survey[ ]


Over the precedent few years, cloud computing has develop into more and more admired. It brings revolutionary innovation with regards to cost, resource management and utilization. Cloud computing offer nearly unlimited resources, highly reliable on-demand services with minimal infrastructure and operational cost and storage system. In the cloud storage system with data de-duplication, un-trusted entities including a cloud server and users may cause security threats to the storage system. These services offers to end-users quite than a creation by allocation possessions, software and other information, hence economic benefit and data de-duplication is the key for Cloud in terms of capital and operational expenditure.

Finding the Relationship between Students’ Performance and Preferences Using Online and Offline Assessments[ ]


Traditional format of assessment, paper and pencil testing involves human errors in the evaluation phase and this decreases the fairness of assessment. E-assessment is a good technique to remove the human errors involved in paper and pencil testing. It also increases the fairness of assessment applying some rules. For this, I used a new technique in which closed subjective questions are assessed electronically. This is an addition to previous research that was used only for objective questions for e-assessment. I also checked the fairness and validity of e-assessment using matching type assessment and contributed Claire Hewson’s research work that used MCQS assessment to check the validity and fairness of online assessment methods. I founded the relationship between students’ performance and preferences using online and offline assessments. Statistics is applied to gathered data from students to find out the results and conclusion is based on the found results. The results show that the respondents liked and preferred e-assessment than offline assessment. The results also show that e-assessment is a valid and a fair way to assess the performance of the students. There is a positive relationship between students’ performance and preferences using online assessment with drag and drop mechanism.
