Research ArticleOpen accessIn the abstractResemblance of Rain Fall in Bangladesh with Correlation Dimension and Neural Network LearningAbu Nasir Mohammad Enamul Kabir, Hussain Muhammad Imran Hasan, Mohd Abdur Rashid et al.Rain fall and Temperature are undoubtedly two important factors that balance water in the environment. Adequate study of the rain behavior helps to forecast it. The time series obtained from different stations of the country throughout the several years are collected and analyzed. The dynamics of rain fall time series is analyzed with Correlation Dimension (CD) to characterize the several … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 7,234 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVENT-DRIVEN BUSINESS INTELLIGENCE APPROACH FOR REAL-TIME INTEGRATION OF TECHNICAL AND FUNDAMENTAL ANALYSIS IN FOREX MARKETMohammed AbuHamad, Masnizah Mohd, Juhana SalimForex market is the most liquid financial market and the largest market in the world. Forex market has been analysed using two isolated approaches, technical analysis and fundamental analysis. Technical analysis attempts to predict the movement of prices by studying the historical data of the market whereas fundamental analysis concerns essentially with the overall state of the economy. Relying on … …Journal of Computer Science, Vol. 9, Issue 4 · 13 May 2013 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Positioning of Laser Beams Using Proportional Integral Derivative and Based Observer-Feedback ControlKwabena A. Konadu, Sun Yi, Wonchang Choi, Taher Abu-LebdehHigh-precision positioning of laser beams has been a great challenge in industry due to inevitable existence of noise and disturbance. The work presented in this study addresses this problem by employing two different control strategies: Proportional Integral Derivative (PID) control and state feedback control with an observer. The control strategies are intended to stabilize the position of a laser beam … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 19 Apr 2013 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Unique Novel Approach for Design and Analysis of A Robust Decentralized Self-Tuning Fuzzy PI Controller for a Multi Input Multi Output ProcessP. Sujatha Therese, N. Kesavan NairProblem statement: In the real world most of the controlled processes in industries are Multi-Input Multi-Output (MIMO) in nature.They have more than a single controlled variable that should be manipulated in order to achieve the desired control performance. Approach: Control of non linear Multi Input Multi Output processes, it is a difficult task because of the non stationary behaviour, substantial … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 17 Jan 2012 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing an Adaptative Fuzzy-Logic System to Optimize the Performances and the Reduction of Chattering Phenomenon in the Control of Induction MotorM. M. Krishan, L. Barazane, A. KhwaldehProblem statement: Neural networks and fuzzy inference systems are becoming well-recognized tools of designing an identifier/controller capable of perceiving the operating environment and imitating a human operator with high performance. Also, by combining these two features, more versatile and robust models, called “neuro-fuzzy” architectures have been developed. The mo Approach: Motivation behind the use of neuro-fuzzy approaches was based on … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractGravity Assist and Scattering off AGB Stars off Molecular CloudsAhmad Hashem AbdelhadiThe scattering of stellar orbits by galactic molecular clouds is studied in hope of explaining isotopic peculiarities of presolar grains from Asymptotic Giant Branch (AGB) stars. Silicon isotopic anomalies found in the mainstream Silicon Carbide (SiC) grains are observed to have heavy isotopes enriched. To explain the isotopic heaviness I propose that AGB stars that formed in the interior region … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow of Dividends under a Constant Force of InterestJuma Kasozi, Jostein PaulsenThis study addresses the issue of maximization of dividends of an insurer whose portfolio is exposed to insurance risk. The insurance risk arises from the classical surplus process commonly known as the Cramér-Lundberg model in the insurance literature. To enhance his financial base, the insurer invests in a risk free asset whose price dynamics are governed by a constant force … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,386 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeedback Control of Quad-Rotors with a Matlab-Based SimulatorStephen Armah, Sun Yi, Wonchang Choi, Dongchul ShinPrecise regulation of position and attitude (roll, pitch and yaw) is one of the most critical tasks to be considered in designing controllers for quadrotor types of Unmanned Aerial Vehicles (UAVs). The MATLAB-based simulator for quadrotors using PD-feedback control to achieve stabilization was developed. MATLAB/Simulink models are used to design and validate the control algorithms and the simulation results are … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 23 Jun 2016 · 7,865 accessesView PDFCite
