Research ArticleOpen accessIn the abstractAn Efficient Method for Fetal Electrocardiogram Extraction from the Abdominal Electrocardiogram SignalMuhammad Asraful Hasan, Muhammad Ibn Ibrahimy, Mamun Bin Ibn ReazProblem statement: FECG (Fetal Electrocardiogram) signal contains potentially precise information that could assist clinicians in making more appropriate and timely decisions during pregnancy and labor. Approach: Conventional techniques were often unable to achieve the extraction of FECG from the Abdominal ECG (AECG) in satisfactorily level. A new methodology by combining the Artificial Neural Network (ANN) and Correlation (ANNC) approach had … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Peak Load Electricity Demand Using Statistics and Rule Based ApproachZ. Ismail, A. Yahya, K. A. MahpolProblem statement: Forecasting of electricity load demand is an essential activity and an important function in power system planning and development. It is a prerequisite to power system expansion planning as the world of electricity is dominated by substantial lead times between decision making and its implementation. The importance of demand forecasting needs to be emphasized at all level as … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Gold Prices Using Multiple Linear Regression MethodZ. Ismail, A. Yahya, A. ShabriProblem statement: Forecasting is a function in management to assist decision making. It is also described as the process of estimation in unknown future situations. In a more general term it is commonly known as prediction which refers to estimation of time series or longitudinal type data. Gold is a precious yellow commodity once used as money. It was made … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 11,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Method of the Combination of Forecasts Based on Rough SetsEslam Faik Ahmed, Wang Jia Yang, Maan Younis AbdullahProblem statement: A study in Analytic Hierarchy Process (AHP) had shown the problem of quantify the qualitative and the side Combined. Approach: So that problems were better resolved. The rough sets theory and AHP was introduced in the study, furthermore, these were united to create a completely new method of combination forecasts. Results: The results of numerical examples were shown … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplying Simulated Annealing For Optimal Operation of Multi-Reservoir SystemsF. Khodabakhshi, A. R. Ghirian, N. KhakzadThe need to optimize the operation of water reservoirs is an issue that is becoming increasingly a concern for water resources planners in developing countries. This issue particularly becomes more significant in large systems with multiple reservoirs where operation of one reservoir has an impact on the others. In other word, the set of reservoirs in these systems act like … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency Comparison of Operational and Profitability: A Case of Hong Kong Commercial BanksCheng-Ru Wu, Hui-Yin Tsai, Ya-Mei WangProblem Statement: Traditional DEA models deal with measurements of relative efficiency of DMUs regarding multiple-inputs vs. multiple-outputs. One of the drawbacks of these models is the neglect of intermediate products or linking activities. The objectives of this study were: (i) This research was shown how to use DEA by two stages, with outputs from the first stage becoming inputs in … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Data Mining Tools Cumulating with a Proposed Data Mining MiddlewareL. E. Hen, S. P. LeeData mining has becoming increasingly popular in helping to reveal important knowledge from the organization's databases and has led to the emergence of a variety of data mining tools to help in decision making. Present study described a test bed to investigate five major data mining tools, namely IBM intelligent miner, SPSS Clementine, SAS enterprise miner, oracle data miner and … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Impact Assessment for Potential Continuous Processes for the Production of Carbon NanotubesAditi Singh, Helen H. Lou, Ralph W. Pike et al.As an emerging discipline, nanotechnology has the potential to improve environmental sustainability through its application in pollution prevention, treatment, remediation, etc. One challenging issue in the growth of nanotechnology is how to produce purified carbon nanotubes (CNT) in commercial quantities at affordable price and with low environmental impacts. A detailed assessment of such a manufacturing process from both economic and … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransforming Spatio-Temporal Yield Maps to Classified Management Zone Maps for Efficient Management of Oil PalmAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm plantations today is proper interpretation of yield maps for site-specific management and development of classified management zone maps for its efficient management. A study was conducted on an on-going fertilizer response trial in Sabah, Malaysia to examine the possibility of converting spatio-temporal yield maps of oil palm to classified management zone maps … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Mathematical Programming Approach to DEA ModelsA. Azadeh, S.F. Ghaderi, Z. Javaheri, M. SaberiEvaluating the performance of activities or organizations by traditional Data Envelopment Analysis (DEA) as efficiency frontier analysis models requires crisp input/output data. However, in real-world problems inputs and outputs are often imprecise. This study develops DEA models using imprecise data represented by fuzzy sets. An important outcome of assessing relative efficiencies within a group of Decision Making Units (DMUs) in … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,223 accessesView PDFCite
