Novel solid state solar cell made from n-cu2o using granular active carbon as upper - electrode
(2015)Coir is a natural vegetable fibre obtained from the coconut tree. In this research, alkaline-bio scoured bristle coir fibres powders were subjected to alkaline activation method. Potassium Hydroxide (0.1M) was used to treat ... -
On an Algorithm to Prove the Strong Goldbach Conjecture
(2015)The strong Goldbach conjecture says that any even number greater than the integer can be expressed as the sum of two prime numbers which has been numerically justified up to such large numbers that of order 4 . We assume ... -
Optimized Power Output from Piezoelectric Flexure Element Driven by Low Frequency Vibration
(2015)Energy harvesting is the process of capturing readily available energy and converting into usable energy. Among the many different types of energy harvesting methods, piezoelectric energy harvesting has become popular as ... -
p-CuSCN (band gap=3.1eV) Sensitized Cu2O Quantum Dots (QDs) Photoelectrochemical Cell
(2015)This work focuses on making photoelectrochemical cell for the first time by sensitizing p-CuSCN with Cu2O quantum dots (QDs). Copper (I) thiocyanate (CuSCN) is wide band gap material which is sensitive only to UV light. ... -

A Stochastic Model for Variation of Exchange Rates in Sri Lanka
(2015)In Sri Lankan economy, exchange rates have been a one of the critical factors as domestic inflation mostly occurs on depreciation of currency value. Exchange rate is the rate at which currency of a country is bought and ... -
Under Frequency Load Shedding Based on Dynamic System Information
(2015)Under Frequency Load shedding is an effective mechanism to prevent a disturbance – induced collapse of a power system. Ceylon Electricity Board (CEB) also uses such a system with the support of under frequency load shedding ... -
Validation of OpenFOAM as Computational Fluid Dynamics (CFD) Software
(2015)Computational Fluid Dynamic (CFD) software is doing a critical role in the modern era of engineering. It is very important especially to the aeronautical and aerospace engineering fields. New CFD software comes in to the ... -
Volatility Models for World Stock Indices and Behaviour of All Share Price Index
(2015)The purpose of the study is to model the volatility of the world stock indices. The word volatility is derived as the results of unequal variances of the error terms of the return series. The technical term used here is ...
