    Derivation of Bessel function closed-form solutions in zero dimensional φ4-field theory
    (Elsevier Ltd, 2022-02) Munasinghe, R. M.
    The integral is used as an introductory learning tool in the study of Quantum Field Theory and path integrals. Typically, it is analyzed via perturbation theory. Closed-form solutions have been quoted for which I could not find any derivation. Using a simple and elegant transformation, the close form solutions for the integral and its even positive integer moments can be obtained in terms of Bessel functions.

    Cognitive Complexity Applied to Software Development: An Automated Procedure to Reduce the Comprehension Effort
    (Institute for Research and Community Services, Institut Teknologi Bandung, 2023-05) Wijendra, D.R; Hewagamage, K.P
    The cognitive complexity of a software application determines the amount of human effort required to comprehend its internal logic, which results in a subjective measurement. The quantification process of the cognitive complexity as a metric is problematic since the factors representing the computation do not represent the exact human cognition. Therefore, the determination of cognitive complexity requires expansion beyond its quantification. The human comprehension effort related with a software application is associated with each phase of its development process. Correct requirements identification and accurate logical diagram generation prior to code implementation can lead to proper logical identification of software applications. Moreover, human comprehension is essential for software maintenance. Defect identification, correction and handling of code quality issues cannot be maintained without good comprehension. Therefore, cognitive complexity can be effectively applied to demonstrate human understandability inside the respective phases of requirements analysis, design, defect tracking, and code quality optimization. This study involved automation of the above-mentioned phases to reduce the manual human cognitive load and reduce cognitive complexity. It was found that the proposed system could enhance the average accuracy of requirements analysis and class diagram generation by 14.44% and 9.89% average accuracy incrementation through defect tracking and code quality issues compared to manual procedures.

    A Methodological Approach for the Quality Assurance of Virtual Platforms Delivering Short-Term Online IT Courses
    (IEEE, 2023-06-12) Munasinghe, B.A; Gamage, M. P. A. W.; Dinesh Asanka, P. P. G.
    Online course delivery democratizes learning throughout life and creates opportunities for knowledge socialization. Short online IT courses have become famous among the audience. This research paper specifies weights by applying the Best Worst Method (BWM) for the dimensions and indicators determined as criteria a platform needs to meet to be a quality short online IT course delivery platform (SOITCDP). In this context, the paper considers thirteen popular SOITCDP and VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method to rank them based on their performance. The Sensitivity analysis ensures that the framework universally applies to evaluating any SOITCDP. The evaluation results are presented through comprehensive and interactive dashboards demonstrated on Power BI. The result of the research depicts that the "Teaching Resources" of the dimensions gained the highest weight while the "Attraction" indicator secured the rank one.The overall performance of platforms showcases that "Udemy" has excelled in all dimensions and indicators. The subsequent study also provides directions for implementing a framework to evaluate the performance of the platforms. The novelty of the research is highlighted on the grounds of implementing a framework unique to the evaluation of short-term online IT courses and the demonstration of results on interactive dashboards.
