Research ArticleOpen accessIn the keywordsA Comparison of Spatio-Temporal Bayesian Models for Reconstruction of Rainfall Fields in a Cloud Seeding ExperimentSujit k. sahu, Giovanna Jona Lasinio, Arianna orasi, Kanti V. MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch Control of a Rocket with a Novel LQG/LTR Control AlgorithmAliyu Bhar Kisabo, Aliyu Funmilayo Adebimpe, Sholiyi Olusegun SamuelThis paper presents the design, simulation and analysis of a novel LQG and LQG/LTR control algorithm for the pitch angle of a sounding rocket. These improved LQG and LQG/LTR control algorithms stem from the fact that a Riccati Differential Equation (RDE) rather than the popular Algebraic Riccati Equation (ARE) is used to obtaining the Kalman gain in the observer of … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 12 Mar 2019 · 7,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Object Detection Technique for Hazard Avoidance SystemsSupreet Kaur Deol, P.W.C. Prasad, Abeer Alsadoon, A. ElchouemiHazard detection and avoidance at construction sites working with heavy equipment and moving vehicles is one of the biggest issues in modern surveillance. Background subtraction using a Gaussian Mixture Model (GMM) is widely utilized for identification of moving objects with most existing methods leading to improvements but lacking accuracy of object detection. This paper aims to improve accuracy and processing … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 27 Sep 2018 · 8,198 accessesView PDFCite
Research ArticleOpen accessIn the abstractFDIR Strategy for Sensor Faults During Re-entry FlightGianfranco Morani, Mariangela Di LorenzoIn this study, a Fault Detection, Isolation and Reconfiguration (FDIR) strategy is proposed for dealing with the problem of single sensor faults during a re-entry flight. The proposed algorithms rely on a model based Fault Detection and Isolation. After the generation of a residual through a Kalman filter observer, detection is obtained via the estimation of residual signal statistics while … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 7 Apr 2018 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Channel Estimation and Performance Analysis Using H-Infinity Filter for MIMO-Orthogonal Frequency Division Multiplexing SystemsJoseph Gladwin Sekar, Salivahanan SankarappanThis paper, deals with H-infinity channel estimation technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, in fading channel. Channel estimation is important for wireless applications because, in practical transmission scenario, channel correlation functions are either not known or cannot be easily estimated. It is therefore desirable to have an estimator which is robust to mismatches between the assumed and the … …Journal of Computer Science, Vol. 11, Issue 2 · 29 Jan 2015 · 6,827 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Signal Processing Techniques for Detection of Power Quality EventsAbhijith Augustine, Ruban Deva Prakash, Rajy Xavier, Mareeta Cheriyan ParasseryThe challenging process industry requires true power for its smooth functioning and here comes the importance of good power or power. The term Power Quality (PQ) aims at supplying true power to the process. The scope of the power quality increased with the introduction of newly designed sophisticated devices like computers and microcontrollers. The performances of these devices are extremely … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 30 Apr 2016 · 8,498 accessesView PDFCite
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 · 7,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF ANFIS FOR GPS-AIDED INS UAV MOTION SENSING AT SHORT TERM GPS OUTAGEChot Hun Lim, Tien Sze Lim, Voon Chet KooThe recent improvement in Micro-Electro-Mechanical System (MEMS) technology has enabled the evolvement of Inertial Navigation Unit (INU) to be built on top of a low cost, small size Integrated Circuit (IC) chip. Due to the nature of the MEMS INU, its outputs are normally corrupted by the resided stochastic noise. A common practice to regulate its measurements into usable motion … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 8,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE ERROR REGISTRATION TECHNIQUE FOR MANEUVERING RADAR NETWORKLiu Yu, Wang Haipeng, Xiong Wei, He YouThis study studies are error registration algorithm for the maneuvering radar network, which is one of the difficult problems of multi-sensor registration. When the maneuvering radar has no orientation bias, measurement equations of both attitude bias and measurement bias can be established by using the common targets observed by different radars. Based on the equations, the real-time estimation of both … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,584 accessesView PDFCite
