Research ArticleOpen accessEvery word in the titleDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,067 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Volatility and Asymmetry of Won/Dollar Exchange RateSeok Yoon, Ki Seong LeeThe study on volatility and asymmetry of the exchange rate by applied to the daily Won/Dollar exchange rate shows that past volatility of the exchange rate still has strong persistency at present and asymmetry effect and the leverage effect, which explain that volatility shock has an effect on the uncertainty of the exchange rate, are also existent after the free … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 8,570 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModelling and Forecasting Volatility of Returns on the Ghana Stock Exchange Using Garch ModelsFrimpong Joseph Magnus, Oteng-Abayie Eric FosuThis paper models and forecasts volatility (conditional variance) on the Ghana Stock Exchange using a random walk (RW), GARCH(1,1), EGARCH(1,1), and TGARCH(1,1) models. The unique ‘three days a week’ Databank Stock Index (DSI) was used to study the dynamics of the Ghana stock market volatility over a 10-year period. The competing volatility models were estimated and their specification and forecast … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,554 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKey Exchange Protocol in Elliptic Curve Cryptography with No Public PointK. Kaabneh, H. Al-BdourIn recent years some cryptographic algorithms have gained popularity due to properties that make them suitable for use in constrained environment like mobile information appliances, where computing resources and power availability are limited. One of these cryptosystems is Elliptic curve which requires less computational power, memory and communication bandwidth compared to other cryptosystem. This makes the elliptic curve cryptography to … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,069 accessesView PDFCite
