    Event Detection and Latency Analysis in High Frequency Trading Dashboards
    (Department of Mathematics and Statistics, Faculty of Humanities and Sciences, SLIIT, 2025-10-10) de Silva, U; Perera, S; Liyanage, U.P; Erandi, H
    High frequency trading relies on millisecond-level decisions, where profitability is strongly influenced by both market responsiveness and system latency. Traditional dashboards offer real-time visualizations but fall short in detecting abrupt regime shifts or quantifying latency. This study presents an AI-aided Market Pulse and Latency Panel that integrates candlestick pattern recognition, change point detection and latency measurement into a unified dashboard. The system detects technical patterns, identifies structural market shifts, and quantifies infrastructural bottlenecks. Experimental results demonstrate that the panel enhances situational awareness by combining event detection with latency analytics, providing traders with actionable insights for strategy adjustment and infrastructural optimization.

    Unpacking how the Living Arrangements of Undergraduates Influence Quality of Life
    (School of Psychology. Faculty of Humanities and Sciences, SLIIT, 2025-10-10) Bandara, K; Abeysekara, M; Vihangi, S; Perera, S; Jayasekara, S; Samaratunge, T; Goonetilleke, N
    This study examined the connection between undergraduate students' living arrangements (private vs rented accommodation) and their Quality of Life (QoL) at the Sri Lanka Institute of Information Technology (SLIIT). All four domains of quality of life, psychological well-being, physical health, environmental factors, and social relationships were measured using an adapted version of the World Health Organisation Quality of Life: Brief Version (WHOQOL-BREF). The cross-sectional studyincluded a sample of 64 individuals obtained from the campus premises between the ages of 18-25. Multivariate Analysis of Variance (MANOVA) revealed no statistically significant differences in QoL dimensions based on accommodation type. However, the effect sizes indicate living arrangements to be a better predictor of the environmental factors as opposed to other domains of QoL. Furthermore, a chi-square test yielded a strong association between the year of study and living arrangements among students, suggesting that the year of study may have an impact on students’ choice of accommodation. These results further demonstrate the diversity of QoL and imply that, although environmental influences are worthy of consideration, living arrangements might not be a strong factor to explain students’ well-being. While the nature of the sample (i.e., small and convenient) may have hindered the statistical significance of the study, the present findings highlight the necessity for subsequent studies to accurately uncover the impact of student life, accommodation, and other related factors onthe quality of life.

    Influence of IoT on Warehouse Management Performance in the Global Context: A Critical Literature Review
    (SLIIT Business School, 2023-12-14) Perera, S; Pinto, A; Sewmini, H; Ulugalathenne, A; Thelijjagoda,S; Karunarathna,N
    This systematic research paper explores the impact of Industry 4.0 technology, specifically the Internet of Things (IoT), on Warehouse Management Performance (WMP) in the worldwide logistics sector. IoT serves as a pivotal component in the paradigm shift towards Industry 4.0, facilitating the seamless storage, packaging, and distribution of commodities. By harnessing interconnected devices and data-driven insights, warehouses have undergone significant transformations since the inception of IoT technology. This study reviews state-of-theart literature on the influence of IoT on WMP, emphasizing the vital role warehouse operations play in ensuring the smooth functioning of the supply chain management process. Warehouse operations encompass aspects ranging from planning and layout to receiving, order picking, shipping, and distribution. To optimize warehouse operations, we conduct a comprehensive literature assessment using Scopus as our primary database. The findings from this systematic review indicate that the integration of IoT technologies such as RFID, QR codes, scanners, and Warehouse Management Systems (WMS) can substantially enhance warehouse management performance. These technologies provide real-time data, predictive maintenance, and improved inventory accuracy, resulting in increased operational efficiency, reduced operational expenses, and improved customer satisfaction. Additionally, the IoT framework combines big data, blockchain, cloud computing, and wireless sensor networks to tackle key challenges related to data storage, retrieval, and utilization. This integration significantly improves the effectiveness of the warehouse management process and facilitates data-driven decision-making. Furthermore, IoT's communication capabilities enhance efficiency and reduce costs in warehouse operations. In conclusion, this systematic review underscores the transformative potential of IoT technology in the global logistics sector. It highlights the importance of technological integration, data-driven decision-making, and smart packaging solutions. Recognizing the disruptive effects of IoT on the logistics industry, it emphasizes the need for companies to adopt and leverage IoT technologies to remain competitive and agile in the evolving global supply chain landscape.

    Impact to the Quantity Surveyors Due to the Current Economic Crisis in Sri Lanka
    (Sri Lanka Institute of Information Technology, 2023-03-25) Manawasinghe, S.I; Gunarathna, N; Perera, S
    This research focuses on the impact to the Quantity Surveyors due to the current economic crisis in Sri Lanka. The Easter bomb attack, covid 19 pandemic, and political instability can be seen as the proximate causes of the current economic crisis, while there were many structural issues of the local economy which had paved way for the same. As a developing country, the crisis had a stronger impact on the construction industry than other industries of the economy. The main reasons for the collapse of the construction industry are the suspension of construction projects by the government, the increase in the price of construction materials, the lack of investors to invest in new projects, and bottlenecks in terms of wrong policy directives. The professionals in the construction industry were severely impacted by the downfall. Among the professionals in the construction industry, this study focusses on QSs- (Quantity Surveyors). Thirty (30) semi-structured interviews were carried out in terms of data gathering. The survey findings demonstrated the type of organization and working experience of QSs. The collected data were analyzed using techniques of thematic analysis. Moreover, the findings identified factors which were the challenges due to current economic crisis and proposed strategies to help overcome those challenges

    Study on the Impact of Cost Controlling Techniques in Mini Hydropower Projects in Sri Lanka
    (Sri Lanka Institute of Information Technology, 2023-03-25) Hirunika, S; Gunarathna, N; Perera, S
    Due to the worst economic crisis, Sri Lanka is currently facing sporadic power failures. There is a lack of dollar reserves to pay for the fuel suppliers and the existing national grid network has failed to power the whole nation. The prevailing situation is becoming quite challengeable since there is a huge power crisis due to the shortage of fuel oil which causes to fail whole operations of oil power plants. Therefore, Sri Lanka has relied on hydropower for a majority of its electricity needs. The share of mini hydropower power plants is performing a significant role in contemporary electricity generation considering national policy targets in order to move with sustainable green energy. Consequently, the necessity of the establishment of MHP plants has become higher but there are significant cost overrun factors identified in the construction phase of MHP projects. This research was carried out to identify the cost overrun factors in MHP projects in Sri Lanka. As a result, efficient cost-control measures will be required to address the above matter. Therefore, it was expected to explore the current practices of cost control techniques used in infrastructure projects based on the findings. Various cost control approaches have been created from time to time throughout the last few years. These may include Earn Value Management (EVM), performance reviews, variance analysis, value engineering, site meetings, work programmes, daily material and labor controlling, etc. The data collection process was conducted through questionnaire surveys which are distributed between industry professionals who have enough knowledge and experience regarding the MHP projects. The set of data was converted into quantitative values and collected data from the questionnaire surveys were evaluated by using percentage analysis and weighted score analysis. The results indicates the challenges in current cost control practices and identify the mechanisms to overcome those challenges and determine their effectiveness in mini hydropower project delivery in Sri Lanka.
