  • Abnormalities of cortical thickness, subcortical shapes, and white matter integrity in subcortical vascular cognitive impairment. 
    Thong, Jamie Yu Jin; Du, Jia; Nagulan, R.; Dong, Yanhong; Soon, Hock Wei; Saini, Monica; Tan, Ming Zhen; Ta, Anh Tuan; Chen, Christopher; Qiu, A (Wiley Online Library/Human Brain Mapping, 2014-05)
    Subcortical vascular cognitive impairment (sVCI) is caused by lacunar infarcts or extensive and/or diffuse lesions in the white matter that may disrupt the white matter circuitry connecting cortical and subcortical regions ...
  • Adaptation of brain functional and structural networks in aging 
    Lee, A.; Nagulan, R.; Tuan, T.A.; Chen, S.H.; Qiu, A. (Public Library of Science/PLOS ONE, 15-04-15)
    The human brain, especially the prefrontal cortex (PFC), is functionally and anatomically reorganized in order to adapt to neuronal challenges in aging. This study employed structural MRI, resting-state fMRI (rs-fMRI), and ...
  • Algorithm aspects of Rubik’s Cube 3D game 
    Subaramya, V.; Krishnakumar, K. (The Open University of Sri Lanka, 28-11-13)
    The Rubik's Cube is really captivating and fascinating puzzle. It is a 3D game. In the literary survey, there are several applications available in Rubik’s cube. Some of them are games, some of them have solution. But there ...
  • Discriminative Patterns of White Matter Changes in Alzheimer's 
    Subaramya, S.; Kumaralingam, L.; Kokul, T.; Pinidiyaarachchi, U.A.J.; Nagulan, R. (Elsevier, 2023-01)
    Changes in structural connectivity of the Alzheimer's brain have not been widely studied utilizing cutting-edge methodologies. This study develops an efficient structural connectome-based convolutional neural network (CNN) ...
  • Improved LARS Algorithm for Adaptive LASSO in the Linear Regression Model 
    Kayanan, M.; Wijekoon, P. (Asia Pacific Publishers, 2024-06-15)
    The adaptive LASSO method has been employed for reliable variable selection as an alternative to LASSO in linear regression models. This paper introduces an adjusted LARS algorithm that integrates adaptive ...
  • A Modified Algorithm to Find Longest Common Subsequences and Optimizing Space, Time 
    Thilaganathan, S.; Jeyamugan, T. (Science Domain International, 2024-12-29)
    "In the study of Longest Common Subsequence (LCS) is an important topic and an important component in the application of Computational Mathematics. The LCS problem is to find a subsequence which is common to at least two ...
  • Phase space error control with variable time-stepping algorithms applied to the forward Euler method for autonomous dynamical systems 
    Vigneswaran, R.; Thilaganathan, S. (Advances in mathematical sciences, knowvel, 2019-03-31)
    We consider a phase space stability error control for numerical simulation of dynamical systems. Standard adaptive algorithm used to solve the linear systems perform well during the finite time of integration with fixed ...
  • Solution of Laplace Transform by Modified Differential Transform Method 
    Kularathna, R.S.M.; Kajan, N.; Jeyamugan, T.; Thilaganathan, S. (Science Domain International, 2024-03-29)
    In this paper, we applied the modified two-dimensional differential transform method to solve Laplace equation. Laplace equation is one of Elliptic partial differential equations. These kinds of differential equations have ...
  • Stochastic Restricted Modified Mixed Logistic Estimator 
    Kayathiri, T.; Kayanan, M.; Wijekoon, P. (Austrian Statistical Society, 2025-05-28)
    In this study, we introduce a new estimator named the Stochastic Restricted Modified Mixed Logistic Estimator (SRMMLE), which is specifically designed to handle multicollinearity within the framework of stochastic linear ...
