The term “Big data” has gained huge popularity in recent years and it is rapidly becoming a new technology trend and a major strategic weapon for business organizations seeking to gain a competitive advantage. 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.

Biomass has already taken its much-needed attention as an energy source due to its zero carbon emission and renewability. 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.

A mathematical formula was derived to predict the porosity of pervious concrete (PC) at its fresh state. 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. The porosity values calculated by the mathematical model and the tested porosity show a very strong linear relationship.

This paper discusses the use of electromagnetic method of partial discharge detection for detecting and localizing partial discharges in high voltage insulators. In a power system, the condition of power line insulation used in transmission and distribution networks play a vital role in providing an uninterrupted power supply. Partial discharges that form in the insulators may be one of the main reasons for the failure of power line insulators. Therefore, pre-identifying partial discharges in high voltage insulators is essential in maintaining a reliable power system. In this study, a log periodic antenna is designed in order to detect the electromagnetic signals emitted from partial discharges, which are in a wide frequency band. Although the acoustic method can be used to localize the source of partial discharges, background noise can interfere with the process. Thus, in order to detect the electromagnetic signals in the wide frequency band, a log periodic antenna in the range 0.9 – 2 GHz has been designed. To localize and measure the severity of the source of partial discharges on the insulators, the designed antenna is mounted on an unmanned aerial vehicle.

News aggregators help readers to handle large numbers of news items in a convenient manner by collecting them into a single place with meaningful groupings. Such news aggregators/clusters are available for English and some other popular languages. However, no such tools are available for Sinhala language. To address this void, this paper presents a system to collect news articles published across the web and group related articles using corpus-based similarity measures. Despite the simplicity of the technique and morphological richness of Sinhala, we achieved very promising results that prove the viability of the presented technique.

Piezoelectric energy harvesting has become popular among researchers because of the ease of converting mechanical energy into electrical energy using piezoelectric materials. In this context, a vibration energy harvesting device was developed to harvest vibration energy from vehicles. Lead zirconate titanate (PZT) was selected as the piezoelectric material. First the vibration sources were analyzed to identify the resonant frequency. Piezoelectric energy harvester was developed using the cantilever type configuration. Euler–Bernoulli beam theory was used to analyze the cantilever beam under free vibration. Finite element analysis (FEA) was used to identify the design parameters of the prototype which includes the metal beam, tip mass and the PZT plate. The maximum theoretical voltage was obtained as 5.99V according to the FEA modeling. The prototype was developed and voltage was measured fixing the prototype to the motor bike. The average voltage output was 3.65V.

Hydropower is the oldest and the main renewable source of electricity generation in Sri Lanka. It has two main sources i.e. conventional and non-conventional. The available conventional hydro resource in Sri Lanka has already been harnessed to its maximum economic potential. 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). The potential increment of mini-hydropower generation is evaluated with coal and fossil fuel displacement.

The design of water retaining structures is mainly based on the serviceability limit state crack control. The allowable crack width depends on the self-healing ability of concrete and the use of supplementary cementitious material like fly ash in concrete mixes might affect it. Therefore, an experimental investigation was carried out to find the influence of fly ash on self-healing process. Water is sent through artificially induced cracks in a specimen for autogenous healing to take place at a constant pressure gradient across the specimen. To determine the level of self-healing, the flow through the crack was measured with time to obtain the sealing time. Fly ash percentages of 20%, 30% and 40% were tested along with a 0% fly ash mix. Insignificant variation was shown for initial drop in flow rate across fly ash percentages used in this study. Significant reduction in sealing time was observed for 20% and 30% fly ash mixes as compared to 0% fly ash whereas higher fly ash percentages (40%) showed insignificant reduction.

While the application of agile principles leads to better project success, some projects still fail due to insufficient understanding of client’s exact requirements. 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.

Air transport network plays a major role in catalyzing globalization through facilitating the movement of goods and people between countries. This study analysed the connectivity of the airline network of the national carrier of Sri Lanka and identified the critical airports and their impact to the network. The study considered the network of Sri Lankan Airlines for the analysis and used flight stats data for data collection. Dubai International Airport (DXB), Delhi International Airport (DEL) and Kuala Lumpur International Airport (KUL) had the highest degree centrality in the network, indicating strong connectivity with other nodes in the network. Thus the most critical airports in the network. While Gan International Airport (GAN) and Seychells International Airport (SEZ) indicated the lowest degree centrality. Degree centrality of the nodes in the networked changed when critical airports were removed from the network. Combaitre International Airport (CJB) is having the highest closeness centrality indicating the ease of movement between the nodes. Removing the critical airports with from the network affected the closeness centrality score of the nodes.
