Research ArticleOpen accessPhrase in the titleExtended Kalman Filter versus Newton-Lowe's Method for Robot Pose EstimationMohammad Ehab RagabIn this work, we study the pose estimation problem of anautonomous mobile robot. Particularly, we compare the Extended Kalman Filter (EKF) to Lowe's method based on the iterative Newton's method for solving a system of nonlinear equations. Although the EKF is recursive which renders it suitable for the real-time problem at hand, Lowe's method has much less dimensionality. This is … …Journal of Computer Science, Vol. 11, Issue 7 · 5 Nov 2015 · 6,937 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCOMPARATIVE STUDY OF DIFFERENT KALMAN FILTER IMPLEMENTATIONS IN POWER SYSTEM STABILITYH. H. Goh, C. W. Tai, Q. S. Chua et al.Voltage stability and voltage collapse issues have in recent years begun to constitute an unpleasant warning to the operational security of power systems. Many techniques have been investigated in order to predict the point of voltage collapse. However, there are still several restrictions due to the insufficiency of current system state information. Accompanied by the commencement of the Phasor Measurement … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,190 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsStabilized Controller Design for Attitude and Altitude Controlling of Quad-Rotor Under Disturbance and Noisy ConditionsM. Hassan Tanveer, S. Faiz Ahmed, D. Hazry et al.This article presents a control approach to obtain the better stabilization in attitude and altitude of quad-rotor under different disturbance conditions. In the standard Quad-rotor rotor type UAV, controlling of attitude and altitude is one of the most critical tasks and appropriate controller for stabilization of UAV is essential and necessary. These two controls under various conditions of disturbances was … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 8,524 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsApplying the Holistic Approach to the Physical Sciences and Engineering SystemsJoseph Z. Ben-AsherThe holistic approach is applied to several examples from the field of physics, engineering and systems engineering and its benefits are demonstrated. In all examples a holistic picture is used and studied while ignoring the various details of the discussed problems. Optimal control and optimal estimation approachs are used in the engineering examples. The results show that the holistic approach … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 6,912 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNew Solution for Reducing Doppler Shift in the MB-OFDM System Over High Mobility Multipath Channel for V&I CommunicationSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.The MB-OFDM has been proposed as a good candidate to ensure Vehicle to Infrastructure communication (V&I). Fast moving vehicles present challenges for the proposed system especially for high mobility (250 km h-1). The main objective in this study is to study and investigate the impact of Doppler shift on the quality of transmitted/received signal in terms of Bit Error Rate … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 29 Apr 2015 · 7,170 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTime-Delay Estimation using the Characteristic Roots of Delay Differential EquationsSun Yi, Wonchang Choi, Taher Abu-LebdehProblem statement: For ordinary dynamic systems (i.e., non-delayed), various methods such as linear least-squares, gradient-weighted least-squares, Kalman filtering and other robust techniques have been widely used in signal processing, robotics, civil engineering. On the other hand, time-delay estimation of systems with unknown time-delay is still a challenging problem due to difficulty in formulation caused. Approach: The presented method makes use … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 7 Apr 2012 · 8,082 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIndoor Navigation to Support the Blind Person Using True Pathway within the MapAbbas M. Ali, Md Jan NordinProblem statement: Map creation remains a very active field in the robotics and AI community, however it contains some challenge points like data association and the high degree of accuracy of localization which are seems to be difficult in some cases, more than that, most of these study focus on the robot navigation, without any consideration for the semantic of … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,832 accessesView PDF Cite
