Research ArticleOpen accessIn the abstractCHILD VIDEO DATASET TOOL TO DEVELOP OBJECT TRACKING SIMULATES BABYSITTER VISION ROBOTHanan Aljuaid, Dzulkifli MohamadThis study presents a Child Video Dataset (CVDS) that has numerous videos of different ages and situation of children. To simulate a babysitter’s vision, our application was developed to track objects in a scene with the main goal of creating a reliable and operative moving child-object detection system. The aim of this study is to explore novel algorithms to track … …Journal of Computer Science, Vol. 10, Issue 2 · 16 Nov 2013 · 8,598 accessesView PDFCite
Research ArticleOpen accessIn the abstractImaging Spectroscopy and Light Detection and Ranging Data Fusion for Urban Features ExtractionMohammed Idrees, Helmi Zulhaidi Mohd Shafri, Vahideh SaeidiThis study presents our findings on the fusion of Imaging Spectroscopy (IS) and LiDAR data for urban feature extraction. We carried out necessary preprocessing of the hyperspectral image. Minimum Noise Fraction (MNF) transforms was used for ordering hyperspectral bands according to their noise. Thereafter, we employed Optimum Index Factor (OIF) to statistically select the three most appropriate bands combination from … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Method of Voltage Sag and Swell Estimation for Power System ApplicationsA. Vetrivel, Jovitha Jerome, N. MalmuruganThis study presents four simple mathematical models to build the voltage shape with the knowledge of few parameters and detects voltage sag and swells accurately. Fourier series, cubic polynomial, Rational functions and Sum of Sin functions are used in this study to model the voltage profile. A new algorithm is developed to detect sag or swell in all the four … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 4 Jul 2013 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Neural Network Controller Based Distribution Static Compensator for Voltage Sag MitigationD. Rajasekaran, Subhransu Sekhar Dash, Arun Bhaskar Mayilvaganan et al.Switching of loads, capacitors, along with the proliferation of power electronics equipment, non-linear loads in industrial, commercial and domestic applications have lead to power quality issues in the distribution system. Power quality issues such as voltage sag, voltage swell and harmonics, which are certainly major concerning issues in the present era. These issues can lead to failure or malfunction of … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 21 Jun 2013 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of Transient Stability of Power System Using Solid State Circuit BreakerKalai Murugan Amirthalingam, Raja Prabu RamachandranThe aim of this study is to use a solid state circuit breaker for the improvement of transient stability margin. Long distance AC transmission is often subject to stability problems, which limits the transmission capability. Interconnected power systems suffer from weakly damped swings between synchronous generator and sub systems. The development of modern power system has lead to an increasing … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 7 Jun 2013 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hybrid Method for Automatic Speech Recognition Performance Improvement in Real World Noisy EnvironmentUrmila Shrawankar, Vilas ThakareIt is a well known fact that, speech recognition systems perform well when the system is used in conditions similar to the one used to train the acoustic models. However, mismatches degrade the performance. In adverse environment, it is very difficult to predict the category of noise in advance in case of real world environmental noise and difficult to achieve … …Journal of Computer Science, Vol. 9, Issue 1 · 27 Feb 2013 · 7,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractMatching LSI for Scalable Information RetrievalRajagopal Palsonkennedy, T. V. GopalLatent Semantic Indexing (LSI) is one of the well-liked techniques in the information retrieval fields. Different from the traditional information retrieval techniques, LSI is not based on the keyword matching simply. It uses statistics and algebraic computations. Based on Singular Value Decomposition (SVD), the higher dimensional matrix is converted to a lower dimensional approximate matrix, of which the noises could … …Journal of Computer Science, Vol. 8, Issue 12 · 2 Jan 2013 · 6,671 accessesView PDFCite
