Research ArticleOpen accessIn the abstractHandling Web and Database Requests Using Fuzzy Rules for Anomaly Intrusion DetectionSelvamani Kadirvelu, Kannan ArputharajProblem statement: It is necessary to propose suitable detection and prevention mechanisms to provide security for the information contents used by the web application. Many prevention mechanisms which are currently available are not able to classify anomalous, random and normal request. This leads to the problem of false positives which is classifying a normal request as anomalous and denying access … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractEdge Detection in Gray Level Images based on the Shannon EntropyBaljit Singh, Amar P. SinghMost of the classical mathematical methods for edge detection based on the derivative of the pixels of the original image are Gradient operators, Laplacian and Laplacian of Gaussian operators. Gradient based edge detection methods, such as Roberts, Sobel and Prewitts, have used two 2-D linear filters to process vertical edges and horizontal edges separately to approximate first-order derivative of pixel … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Switching Mechanism Detection to Reduce Complexity in Multiuser Detection for DS-CDMA SystemsRekha Agarwal, B. V.R. Reddy, K. K. AggarwalWe present a reduced complexity switching mechanism which uses either matched filter or Parallel Interference Cancellation (PIC) detector based on channel characteristics. The main criterion of taking PIC detector is that it has less Bit Error Rate (BER) and less processing delay than other nonlinear multiuser detectors. This proposed detector reduces overall complexity while maintaining the same performance as PIC … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2007 · 6,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Pose Tracking based on Line Segment MatchingJunqiu Wang, Jingjing Cui, Yanjie Gao et al.Pose tracking is a crucial issue for many applications such as robotic tasks and facility operations. Vision-based approaches with non-contact properties are appropriate choices for these tasks. However, vision-based approaches are not sufficiently robust and fast. In this work, we propose a vision-based pose tracking to deal with these problems. We estimate poses using Lie group and Lie algebra representation … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 27 Dec 2018 · 7,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Pedestrian Detection Using Context InformationJorge Candido, Mauricio MarengoniDetecting pedestrians among other objects in a digital image is a relevant task in the field of computer vision. This paper presents a method to improve the performance of a pedestrian detection algorithm using context information. A neural network is used to classify the region below pedestrian candidates as being floor or non-floor. We assume that a pedestrian must be … …Journal of Computer Science, Vol. 14, Issue 7 · 6 Aug 2018 · 7,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Development Design of Low Current Measurement with Noise Reduction for High-Resolution SystemNdalla Essengue Gloire, Wembe Tafo Evariste, Djamet Yimga Arnaud et al.The treatment of inoperable cancers in the therapy terminal in Lanzhou-China, which is located at the Institute of Modern Physics (IMP), permits to work on the actual front-end readout. The availability of detailed noise spectral density characteristics for the OPA amplifier helps to develop the noise error analysis for high-resolution. This work focused on the noise model of the detector-preamplifier, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 18 May 2018 · 8,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtracting Unique Personal Identification Number from IrisNenad Nestorovic, P.W.C. Prasad, Abeer Alsadoon, Amr ElchouemiThe aim of this research is to propose an enhanced model that significantly reduces the noise in the iris templates and thus present an efficient and reliable iris recognition system. Accuracy of Iris recognition system significantly depends on reducing noise at every stage of recognition process especially at eye image acquisition and iris segmentation stages. The proposed Iris recognition model … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 7 Jul 2017 · 8,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiological Risks Assessment of Ogun State Drinking WaterJustina Ada Achuka, Usikalu Mojisola Rachael, Oyeyemi Kehinde DavidThe presence of radionuclides in water constitute health risk to man. The consumption of such water increases the likelihood of incurring cancer. Analysis will enhance the detection of significant radionuclides causing harm to the populace and stimulate remediation. This inferred the radioactivity measurements of twenty (20) well water samples from three industrial cities of Ogun State using Hyper Pure Germanium … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 18 May 2017 · 7,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimultaneous Detection of Nitrite and Nitrate in Celeries and CarrotsDongwu Liu, Jinye Niu, Ling Kong, Zhiwei ChenIn this study, the anions nitrite ion (NO2-) and nitrate ion (NO3-) in celeries and carrots were detected with the technique of ion chromatography. A Dionex ICS-2000 ion chromatograph was used to detect the content of NO2- and NO3- in celeries and carrots. NO2- and NO3- were separated on a DIONEX Ionpac AS19 A-4 mm ion-exchange column and an Iopac … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 14 May 2016 · 7,214 accessesView PDFCite
Review ArticleOpen accessIn the abstractArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,782 accessesView PDFCite
