Sri Lankan farmers face several issues and among them crop loss due to insect pest infestation is the major hurdle. Several approaches have been proposed to detect the pest class by using computer vision and machine learning ...
Combining Lasso and Liu type estimator in the linear regression model

Kayanan, M.; Wijekoon, P. (International Statistical Institute, 21-08-19)

The Ordinary Least Square Estimator (OLSE) has been widely used to estimate unknown parameters in the linear regression model. Since OLSE produces high variance on the estimates when multicollinearity exists among the ...
Comparison between r-d and r-k class estimators in Misspecified linear regression model

Kayanan, M.; Wijekoon, P. (Postgraduate Institute of Science , University of Peradeniya, Sri Lanka, 08-09-17)

A significance attention has been paid by researchers about misspecification due to excluding some relevant explanatory variables and multicollinearity among the explanatory variables in linear regression model. Several ...
Electrostatic Discharges (ESD): Rate of Rise of Currents and Radiated Electric Fields

Thirukumaran, S.; Hoole, P.R.P.; Harikrishnan, R.; Jeevan, K.; Hoole, S.R.H. (The Electromagnetics Academy, 2012)

Electrostatic Discharge (ESD) is a major concern in Microelectromechanical Systems (MEMS) as well as in large systems such as in atmospheric electricity. We focus on ESD rate of rise of currents and the radiated electric ...
Enhanced Symmetric Cryptography for IoT using Novel Random Secret Key Approach

Gopinath, S.; Nagulan, R. (IEEE, 2020-12-10)

The deployment of IoT devices in different domains enables technical innovations and value-added services to users but also creates multiple requirements in terms of effective communication and security. IoT devices are ...
Enhancing Predictive Performance of the Logistic Two-Parameter Estimator under Multicollinearity

Kayathiri, T.; Kayanan, M.; Wijekoon, P. (Institute of Applied Statistics, Sri Lanka, 2024)

"This study aimed to propose a new estimator named Modified Logistic Two-Parameter Estimator (MLTPE) with the best predictive performance in logistic regression when multicollinearity exists. The performance of the proposed ...
Extracting knowledge from Noise Information

Chowuraya, T.; Kirushanth, S.; Kabaso, B. (Academic Conference International (ACI), 2018-11-12)

Information is an important part of creating knowledge. We live at a time when so much information is created. Unfortunately, much of the information is redundant. There is huge amount of online information in the form of ...
Finite Element Method based Triangular Mesh Generation for Aircraft-Lightning Interaction Simulation

Vinotha, K.; Thirukumaran, S. (Faculty of Computing and Technology, University of Kelaniya, 2018)

Lightning is a natural electrical discharge process. Most common lightning strike is Cloud-to-Ground. It occurs when the negative charges accumulated at the bottom of the thundercloud traverse towards the ground to neutralize ...
Generalised LARS Framework for Variable Selection in High Dimensional Binary Classification

Kayathiri, T.; Kayanan, M.; Wijekoon, P. (PGIS, University of Peradeniya, 2025)

High-dimensional logistic regression refers to situations where the number of predictor variables exceeds the number of observations in binary classification. This technique is particularly valuable in domains such as ...
Ground to Cloud and Cloud to Ground Lightning Flashes: A Comparative Study

Thirukumaran, S.; Hoole, P.R.P; Harikrishnan, R.; Jeevan, K.; Hoole, S.R.H. (The Electromagnetics Academy, 2012)

Since cloud to ground lightning °ashes are the most common type of earth flashes, it has received much attention with reference to obtaining the engineering parameters such as the electric charge moment (QL, where Q is the ...
A hybrid CNN-HOG based feature extraction approach for tamil handwritten village name recognition using SVM

Yasotha, R.; Vinusha, C.; Ramanan, M. (University of Ruhuna, 2025)

Recognizing village names in handwritten Tamil presents a significant challenge for those working in the postal sector, due to variations in handwriting. This research aims to address this issue by developing and evaluating ...
