A comparative study of the forecasting bility of Backpropagation Artificial Neural Network Models with Learning Rate Adaptation for Colombo Stock Market

Nandani, E.J.K.P.; Wedagedara, J.R. (Faculty of Science, University of Ruhuna, Sri Lanka, 2011-01)

A stock market is one of the fundamental types of financial markets. The stock market can also be thought of as a highly complex and adaptive system. Financial indices defined on stock prices are used as indicators of the ...
Comparison of ARIMA and Neural Network Models for S&P SL(20) Index

Nandani, E.J.K.P.; Mahinda, M.K.; Wedagedara, J.R. (Faculty of Science, University of Ruhuna, Sri Lanka, 2015-01-23)

In the current financial world, prediction of stock prices has become a vital task. Predicting the future is important for the organizations to plan or adopt the necessary policies. Forecasting can assist them to make a ...
Decision Support System for Bank Loan Classification Using Neural Network

Nandani, E.J.K.P.; Wedagedara, J.R. (Faculty of Science, University of Ruhuna, Sri Lanka, 2009-01-01)

We report the designing and application of an Artificial Neural Network (ANN) to classify the consumer loan application in banking sector. The system can be used as a “Second Level” filter, upon which shall be supplied ...
Higher-order local and non-local correlations for 1D strongly interacting Bose gas

Nandani, E.J.K.P.; Romer, R.A.; Tan, Shina; Guan, X-W (IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2016-05-26)

The correlation function is an important quantity in the physics of ultracold quantum gases because it provides information about the quantum many-body wave function beyond the simple density profile. In this paper we ...
Momentum distribution and non-local high order correlation functions of 1D strongly interacting Bose gas

Nandani, E.J.K.P.; Guan, Xi-Wen (Chinese Physical Society and IOP Publishing Ltd, 2018-06-25)

The Bethe ansatz, which was introduced in 1931 by Hans Bethe, has become a powerful method to obtain exact solu tions of one-dimensional (1D) quantum many-body systems. In 1963, Lieb and Liniger[1] solved the 1D ...
The momentum distribution of one-dimensional strongly repulsive Bose gas at large momenta

Nandani, E.J.K.P.; Guan, Xi-Wen (Faculty of Scince, University of Ruhuna, Sri Lanka, 2018-02-15)

The physics of ultracold Bose gases is a rapidly developing field due to the recent remarkable achievement in the experiment and intensive theoretical investigations. However, when understanding quantum correlations, ...
On forecasting ability of the artificial neural network model in time series data: Based on gold price in Sri Lanka.

Gunarathna, I.G.I.S.C.; Nandani, E.J.K.P. (Faculty of Scince, University of Ruhuna, Sri Lanka, 2020-01-22)

Forecasting is the prediction of values of a variable based on known past values of that variable or other related variables. Forecasts also may be based on expert judgments which in turn are based on historical data ...
Pre-harvesting sawn timber valuation system by using neural network

Nandani, E.J.K.P. (Department of Forestry and Environmental Science, University of Sri Jayawardenepura, 2022-07-06)

Trees are a natural resource linked to human existence. Different tree species provide timber with varying properties such as strength, durability, resonance, color, scent, etc. Timber is transformed into a wide range ...
