Research ArticleOpen accessIn the author namesModelling the Error Term of Australia Gross Domestic ProductAyodele Abraham Agboluaje, Suzilah Ismail, Chee Yin YipThe main aim of this study is to model the Gross Domestic Product (GDP) with the new Combine White Noise (CWN) Model and compare the results with the Vector Autoregressive (VAR) Model and Exponential Generalized Autoregressive Conditional Heteroscedasticity (EGARCH) Model which are the existing models. The CWN model estimation yields best results with least information criteria and high log likelihood … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 2 Nov 2016 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetecting Malaysian Housing BubblesYip Chee Yin, Wong Woei Chyuan, Woo Kok HoongThis paper examines whether Malaysia is facing an impending housing bubble by using a graphical analysis, logical deduction and two statistical tests. Our research results are robust and supported by a three prone approach: Logical deduction working on the historical price trend based on most recent research findings on bubble; testing the stability of the price cycle and a statistical … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 20 Mar 2016 · 8,336 accessesView PDFCite
Research ArticleOpen accessIn the author namesTowards Semantic User Query: A ReviewHui-Hui Wang, Yin-Chai Wang, Soo-See ChaiThis paper attempts to discuss the image query mechanisms and user needs for image retrieval. The explosive growth of image data leads to the need of research and development of Image retrieval. Image retrieval researches are moving from keyword, to low level features and to semantic features. Drive towards semantic features is due to the problem of the keywords which … …Journal of Computer Science, Vol. 11, Issue 10 · 4 Jan 2016 · 6,636 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling the Error Term by Moving Average and Generalized Autoregressive Conditional Heteroscedasticity ProcessesAyodele Abraham Agboluaje, Suzilah bt Ismail, Chee Yin YipThis study has been able to reveal that the Combine White Noise model outperforms the existing Generalized Autoregressive Conditional Heteroscedasticity (GARCH) and Moving Average (MA) models in modeling the errors, that exhibits conditional heteroscedasticity and leverage effect. MA process cannot model the data that reveals conditional heteroscedasticity and GARCH cannot model the leverage effect also. The standardized residuals of GARCH … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 20 Nov 2015 · 6,726 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Study on the Effects of Non-Normality on the Performances of Max-DEWMA Versus SS-DEWMA ChartsTeh Sin Yin, Michael Khoo Boon ChongProblem statement: The called the Sum of Squares Double Exponentially Weighted Moving Average (SS-DEWMA) chart which is effective in detecting shifts in the mean and/or variance is compared with the Max-DEWMA (called the maximum double exponentially weighted moving average) chart. The comparison is based on the assumption that the distribution of the quality characteristic of the process is normal or … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 18 Jan 2012 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of Pressure-Slippage-Generating Tactile Mouse using Edge PresentationYiru Zhou, Xuecheng Yin, Masahiro OhkaProblem statement: Although a conventional tactile display can generate distributed pressure, our tactile mouse can generate not only distributed pressure but also slippage force. In previous works, this tactile mouse was effective on virtual figure presentation tests. Advanced tests are required to evaluate this tactile display. Approach: To compare virtual reality presented by the present tactile mouse and a real … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 7,077 accessesView PDFCite
Research ArticleOpen accessIn the author namesAbrasive Jet Polishing and its Applications in Surface FinishingZhaoze Li, Jianmin Wang, Xiaoqiang Peng et al.Problem statement: Single Point Diamond Turning (SPDT) is highly deterministic and versatile in producing various forms of precise optics. A typical example is the production of large off-axis aspheric mirrors and various infrared mirrors and mandrels. However, the fine periodical turning marks left in the surface critically limit its performance and they are difficult to be avoided for traditional polishing … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 26 Jul 2011 · 13,592 accessesView PDFCite
Research ArticleOpen accessIn the author namesDielectric Properties of Ni0.2Zn0.8Fe2O4-Polypropylene CompositesTan Foo Khoon, Jumiah Hassan, Nurhidayaty Mokhtar et al.Problem statement: In the last decade, the studies and investigation on polymer-based composites have drawn significant attention owing to improvement in their mechanical, thermal, electrical, optical and pharmaceutical properties as compared with pure polymer. Approach: Different compositions of Ni0.2Zn0.8Fe2O4 (NZF) and Polypropylene (PP) can alter the useful properties of polymer-based composites. Hence, the determination toward significant percentage of NZF added … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,949 accessesView PDFCite
Research ArticleOpen accessIn the author namesEfficiency 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 · 7,488 accessesView PDFCite
Research ArticleOpen accessIn the author namesCombining ANP and TOPSIS Concepts for Evaluation the Performance of Property-Liability Insurance CompaniesHui-Yin Tsai, Bao-Huey Huang, An Siou WangThis is a significant problem for the property-liability insurance industry. The study first uses Modified Delphi Method to sift influence property-liability insurance effects out norms. Moreover, the evaluation weights are determined using Analytic Network Process (ANP). Finally, the technique for ordering preference by similarity to the ideal solution (TOPSIS) constructs performance evaluation model of property-liability insurance companies in Taiwan. This … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 8,208 accessesView PDFCite
