The main objectives of this research study are to identify the factors determining the intention to adopt big data technology in financial services industry of Sri Lanka and to investigate the nature of relationship between those factors and the intention to adopt big data technology. In order to reach these objectives, a structured questionnaire survey was carried out to collect data from 30 licensed finance companies in Sri Lanka. The data were analyzed by using multivariate quantitative techniques through descriptive and inferential statistical methods. The empirical findings reveal that there is a significant positive association among compatibility, relative advantage, technological resource competency, organizational size, absorptive capacity, competition intensity, regulatory support and organizational intention for big data technology adoption. However, complexity and environmental uncertainty have a significant negative relationship with the same. These findings will have various implications including theoretical and policy implications.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"11 1","pages":"420-425"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84477384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various types, biomass residues such as sawdust and rice husk show economical potential due to their abundance. However, its optimum conversion is utmost necessary for clean and sustainable consumption. The suspension combustion is one of the promising energy conversion technologies for biomass residues. However, because of complex reaction schemes and various characteristic properties of biomass, it has become difficult to optimize the conventional suspension combustor. To overcome these difficulties, a numerical model was developed in this study to analyze the transport phenomena in the combustor. The CFD model was based on Eulerian-Lagrangian concept, which tracks each biomass particle individually with association of multiple physics and thermo-chemical properties. The model was validated using an industrial suspension type combustor.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"4 1","pages":"226-230"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83170940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In agile, new features are introduced to the system in each sprint delivery, and although it may be well developed, the delivery failures are possible due to performance issues. By considering delivery timeline, moving for system scaling is common solution in such situations. But, how much system should be scaled? System scale requires current system benchmark status and expected system status. Benchmarking the production is a critical task, as it interrupts the live system. The new version should go through a load test to measure expected system status. The traditional load test methods are unable to identify production performance behavior due to simulated traffic patterns are highly deviated from production. To overcome those issues, this approach has extended CICD pipeline to have three automation phases named benchmark, load test and scaling. It minimizes the system interruption by using test bench approach when system benchmarking and it uses the production traffic for load testing which gives more accurate results. Once benchmark and load test phases are completed, system scaling can be evaluated. Initially, the pipeline was developed using Jenkins CI server, Git repository and Nexus repository with Ansible automation. Then GoReplay is used for traffic duplication from production to test bench environment. Nagios monitoring is used to analyze the system behavior in each phase and the result of test bench has proven that scaling is capable to handle the same load while changing the application software, but it doesn't optimize response time of application at significant level and it helps to reduce the risk of application deployment by integrating this three phase approach as CICD automation extended feature. Thereby the research provides effective way to manage Agile based CICD projects.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"148 1","pages":"156-161"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73685003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Invasive blood glucose measuring is the current gold standard. It causes discomfort for the patient and sometimes even infections. Researchers around the world have reported different techniques to measure blood glucose levels non-invasively, but a universally acceptable method with required accuracy is not yet available. We proposed a novel approach to measure blood glucose level non-invasively using a hybrid technique combining Near InfraRed (NIR) absorption and bio-impedance measurements. We tested the methods individually first. Then Artificial Neural Network (ANN) and least squares regression were used to integrate the two methods. The combined methods showed better accuracy compared to the individual measurements. The hybrid technique developed using the linear regression models showed a superior outcome with 90% and 10% of the data points in the regions A and B of the Clarke error grid, which are considered acceptable.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"47 1","pages":"7-12"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76510583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Testing scope changes when user stories are added, updated, or deleted. Moreover, test cases need to be re-written or update when user stories change or removed from the sprint, which wastes time and makes agile testers frustrated. Furthermore, the mini-waterfall model adopted within a sprint could develop unwanted stress in agile testers. Despite these challenges little seem to be understood about the challenges faced by agile testers. We fill this gap by closely studying the challenges faced by agile testers in a multinational IT services organization. We first set up a forum for agile testers to discuss their challenges, malpractices, and best practices. We then conducted an online survey based on the findings from the forum and literature review. Through this, we identified 15 challenges and best practices to overcome those 15 challenges. We further conducted a set of interviews with the subject matter expertise to identify a suitable set of solutions such as conducting retrospective in a fun and engaging way, managing story lifecycle using collaborative tools, setting up ground rules for geographically distributed teams, and introducing innovative sprints.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"21 1","pages":"431-436"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74134452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coarse aggregates (CA) within the size ranges of 0.016–0.02m and 0.01–0.014m were used in the study. Pervious concrete was mixed for two stages. A w-c ratio of 0.3 was used in the study. A scaling factor was defined to represent the thickness of cement paste coated around CA. The scaling factor is independent of the size of CA used and their volume based binary combinations. The percentage difference between the two scaling factor values obtained for CA having a size of 0.01–0.014m was calculated to be 1.14 percent. The tested wet density in all PC batches made in the first stage was approximately 170–264kg/m3 lesser than the designed wet density. The difference between the tested porosity values and the porosity values calculated by the mathematical model has been developed is approximately 0.01–0.015m3 for all pervious concrete batches. It was observed that as the scaling factor increases the wet density increases and the porosity reduces.

Agile teams have recently started adopting Design Thinking (DT) practices to better understand what is in customers’ mind. We explore suitable DT practices to satisfy customer expectations in agile teams using inductive reasoning. We first formulated a conceptual framework based on a literature review. We then conducted a set of interviews with fifteen domain experts from ten IT service organizations. Interview findings were then analyzed using the Straussian grounded theory. Customer journey, story mapping, prototypes, POC, and customer profiling were determined to be the most suitable methods to identify the needs of customers. Moreover, practicing human-centered approach through workshops, discussions, team communication, and end-user interaction through UAT were also identified to be effective. We further classified the best practices into five categories as customer’s real need identification, transforming customer’s real needs into pilot solutions, visualizing the pilot solution for customer feedback, idea generation for the pilot solution, and brainstorming. Based on these findings, we also derived a framework to achieve customer satisfaction through the adoption of DT in agile-base projects.","PeriodicalId":6603,"journal":{"name":"2018 Moratuwa Engineering Research Conference (MERCon)","volume":"29 1","pages":"471-476"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85973098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That way, the software system will be delivered as a set of features and the feature set could be decoupled at any time, according to the latest set of requirements without harming to any existing functionality. In this research the final outcome has been a feature oriented domain specific language (DSL). The objective of this developed feature oriented DSL is to make it effective even for business analysts to introduce new features without getting help from the development team of the project.

The non-conventional hydropower generation i.e. mini-hydropower generation is predominantly run of river type. Yet, they are not dispatchable and operate when the flow of water is available. When analyzing the distribution of mini hydro projects, there are a number of locations having the capability of the addition of a storage capacity. It allows the plant to capture a certain amount of water to operate when it is required. This paper presents a comprehensive feasibility analysis of introducing dispatchable mini hydro plants to Sri Lankan power sector through low cost high efficient and environmentally friendly energy solutions. In this research, a technical, economic and environmental feasibility of introducing storage capacity is evaluated for Bulathwatta Mini Hydro Plant (MHP) and Batathota Mini Hydro Plant (MHP).
