Research ArticleOpen accessEvery word in the title3D Modelling for Mechanized Tunnelling in Soft Ground-Influence of the Constitutive ModelNgoc-Anh Do, Daniel Dias, Pierpaolo Oreste, Irini Djeran-MaigreThe main purpose of this study was to provide a three-dimensional numerical model which would allow to show the influence of the constitutive model of the ground on the tunnel lining behaviour and displacement field surrounding the tunnel. Most of the processes that occur during mechanized excavation have been simulated in this model. Besides the well-known elastic linear perfectly plastic … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 8,371 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModelling Knowledge Summarization by Evolving Fuzzy GrammarNurfadhlina Mohd Sharef, Alfian Abdul Halin, Norwati MustaphaSummarized text is a simplified and condensed version of the original text containing highlighted information to help the audience get the gist in a short period of time. Typically, text summarization produces abstract or a paragraph-like outputs by omitting details and irrelevant information. However, the text summary can also be produced in a visualized form, such as a chart, graph … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 10 Jun 2013 · 6,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Square Substrate Integrated Waveguide Cavity Resonators: Compensation of Modelling Errors by Support Vector Regression MachinesGiovanni AngiulliThe design of Substrate Integrated Waveguide (SIW) resonators is usually a cumbersome process, especially due to the length &#34trial and error&#34 procedure involved in this task. In this study Support Vector Regression Machines (SVRMs) are employed to compensate the modeling errors associated to the design of SIW rectangular cavity resonators. To validate the proposed approach, we have compared the design … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 5 Sep 2012 · 6,689 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleToward a Hierarchical Bayesian Framework for Modelling the Effect of Regional Diversity on Household ExpenditurePudji Ismartini, Nur Iriawan, Setiawan, Brodjol Sutijo Supri UlamaProblem statement: Household expenditure analysis was highly demanding for government in order to formulate its policy. Since household data was viewed as hierarchical structure with household nested in its regional residence which varies inter region, the contextual welfare analysis was needed. This study proposed to develop a hierarchical model for estimating household expenditure in an attempt to measure the effect … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 25 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModelling Political Support among Women with Political Actors in Northern StatesZaherawati Zakaria, Kamarudin Ngah, Jamaludin Mustaffa et al.Problem statement: Women in Asia are making their mark with distinct styles of leadership, but have a long way to go to reach the critical mass needed to level a political playing field that remains much easier for men to take part. Yet far from being included in the decision-making process, women find themselves under-represented in political institutions. Approach: Numerous … …Journal of Social Sciences, Vol. 8, Issue 1 · 10 Feb 2012 · 7,631 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMarkov Regime Switching Modelling and Analysis of Socially Responsible Investment FundsEduardo D. Roca, Victor S.H. Wong, Gurudeo Anand TularamProblem statement: An increasing proportion of Australian superannuation funds are being placed in Socially Responsible Investments (SRI). Yet, there is no clarity in the literature as regards the risk and return characteristics of these investments and how their performance is affected by different states of the market and sector. Approach: We examine the sensitivity of Australian SRI Funds to movements … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,378 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleForecasting and Modelling Electricity Demand Using Anfis PredictorM. Mordjaoui, B. BoudjemaProblem statement: Load forecasting plays an important task in power system planning, operation and control. It has received an increasing attention over the years by academic researchers and practitioners. Control, security assessment, optimum planning of power production required a precise short term load forecasting. Approach: This study tries to combine neural network and fuzzy logic for next week electric load … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 14 Sep 2011 · 7,811 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMultivariate Modelling of the Canary Islands Banana Output. The Role of Farmer Income ExpectationConcepción González Concepción, María Candelaria Gil-Fariña, Celina Pestano-GabinoThe EU is the world‘s largest importer of bananas and the only major managed market in the international banana trade. Spain is the main banana producer within the European Union (EU), followed by France and Portugal. In all these countries the fruit is grown in overseas islands situated in tropical or sub-tropical areas and bananas are a pillar of the … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 7,766 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamics Modelling of a Plate Vibrating in a Perfect FluidBouarroudj Nadra, Belaib LekhmissiWe deal with the interaction problem of a plate vibrating within a perfect fluid. We establish the equations describing the dynamics behaviour of the plate using the general equations of the elasto-dynamic. The fluid flow described by the equation of Euler’s low amplitude. We presented results of the existence, the unicity and the regularity of the problem verified by the … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,896 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 · 7,551 accessesView PDFCite
