Research ArticleOpen accessIn the author namesNumerical Solution for 2D European Option Pricing Using Quarter-Sweep Modified Gauss-Seidel MethodKoh Wei Sin, Jumat Sulaiman, Rasid MailProblem statement: This study presents the numerical solution of two-dimensional European option pricing problem based on Quarter-Sweep Modified Gauss-Seidel (QSMGS) iterative method. In fact, the pricing of European option with two-underlying assets can be governed by two-dimensional Black-Scholes Partial Differential Equation (PDE). Approach: The PDE needs to be discretized by using full-, half- and quarter-sweep second-order Crank-Nicolson schemes to generate … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 8 Feb 2012 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the author namesHigh Incidence of Disorder-Promoting Amino Acids in the Amino Terminus of Mature Proteins in Bacillus subtilisGuangqiang Wang, Yining Dong, Haiqin Chen et al.Problem statement: Exported polypeptides are usually synthesized as preproteins which are composed with mature domains and the signal peptides. The foreign proteins are usually inefficiently secreted by the aid of signal peptides. Although we know that the mature protein played an important role in the protein export process, we do not know what properties of the mature domains are critical … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 2 Feb 2012 · 8,258 accessesView PDFCite
Research ArticleOpen accessIn the author namesSingle Step Optimal Block Matched Motion Estimation with Motion Vectors Having Arbitrary Pixel PrecisionsCharlotte Yuk-Fan Ho, Bingo Wing-Kuen Ling, Saverio Giovanni Blasi et al.Problem statement: This study derives the optimal motion vector with arbitrary pixel precisions in a single step. Approach: A non-linear block matched motion model was proposed. Based on the proposed non-linear block matched motion model, the optimal motion vector which minimizes the mean square error was solved analytically in a single step via a gradient approach. Results: The mean square … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 8,207 accessesView PDFCite
Research ArticleOpen accessIn the author namesDynamic Capability and Its Effects on Firm PerformanceKuo-Wei Lin, Kai-Ping HuangProblem statement: The study has been mainly attempted as an extension to previous studies made on dynamic capabilities and their necessity in organizational firms for goals’ accomplishments. Approach: The literature review illustrates the effects of dynamic capabilities on product innovation, firm performance and environmental dynamism. The researches of different authors and theorists on the subject of dynamic capability have been … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,414 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling of Piezoelectric Actuators Based on Bayesian Regularization Back Propagation Neural NetworkWen Wang, Zhu Zhu, Yanding Wei, Zichen ChenProblem statement: Piezoelectric actuator is a kind of key driving components for micropositioning stages, micropumps, micro valves, micro gripper and so on in the fields of micro/nano technology such as integrated circuit manufacturing, precision instruments, ultra precision fabrication, biomedical manipulation. It has lots of advantages including high stiffness, fast response times, less heat generating, low power consumption and large force … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the author namesDamage Pattern and Nesting Characteristic of Coptotermes curvignathus (Isoptera: Rhinotermitidae) in Oil Palm on PeatWei-Hong Lau, Choon-Fah J. Bong, Seow-Phan ChanThe oil palm industry of Malaysia has expanded into peat area in Sarawak. Problem statement: The subterranean termite Coptotermes curvignathus was a serious pest of oil palm on peat. Control of this termite has resorted to heavy usage of chemicals which was deemed uneconomical and hostile to the environment. Baiting system has inconsistent success due to the limited knowledge of … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,666 accessesView PDFCite
Research ArticleOpen accessIn the author namesHeat-Modeling of Microwave Assisted Epoxidation of Palm Acid OilN. Saifuddin, L. Wei Zhan, K. Xin NingProblem statement: While microwave chemistry could well be the most convenient, rapid and energy-saving way to initiate a chemical reaction, the issues of thermal versus microwave specific effect remain unaddressed. Approach: A three-dimensional Finite Element Model (FEM) was developed to predict temperature profile during the enzymatic epoxidation of palm acid oil using microwave heating. Three-dimensional partial differential equations are formulated … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,678 accessesView PDFCite
Research ArticleOpen accessIn the author namesIncorporating Workload and Performance Levels into Work Situation Analysis of Employees with Application to a Taiwanese Hotel ChainTien-Hui Chen, Kun-Hsu Wu, Wei-Jen Lin et al.Problem statement: Appropriate Human Resource Management (HRM) can motivate employees, develop their capabilities and enhance their productivity. However, before selecting the HRM practices to adopt, the workload levels of employees should be considered, since they may influence the success of such efforts. Approach: This study measured the relative workload of individual employees and incorporates the performance level into the work … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,607 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling and Control of a Photovoltaic Energy System Using the State-Space Averaging TechniqueMohd Saifuzam Jamri, Tan Chee WeiProblem statement: This study presented the modeling and control of a stand-alone Photovoltaic (PV) system using the state-space averaging technique.
