Research ArticleOpen accessAll words, across the recordDetection of Soil Total Nitrogen, Phosphorus and Potassium Content Based on the Spectral Information of Citrus CanopyLin Yunshuo, Li Zhen, Lv Shilei et al.The content of total nitrogen, phosphorus and potassium in the soil is an important basis for calculating the best fertilization amount and realizing the reasonable fertilization of the orange planting soil in time and accurately. In this research, hyper-spectral technology is applied to detect the three soil nutrient elements in the cultivated soil of citrus trees. Four spectral bands with … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 17 Apr 2020 · 7,805 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetection of Subsurface Defects in Concrete Bridge Deck JointsWonchang Choi, Larry Rickard, Taher Abu-Lebdeh, Miguel PicornellProblem statement: The integrity of deck joints in highway bridges plays a major role to determine overall performance of bridge system. As the bridge maintenance program, the defects in deck joints have historically been detected by conventional non-destructive testing and evaluation methods such as visual inspection, chain-dragging and by the detecting sounds under the traffic. Future bridge maintenance challenges will … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Dec 2011 · 7,772 accessesView PDFCite

This work has done in an aim to assist the upcoming researchers in the field of video retrieval, to know about the techniques and methods … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 8,579 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,076 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordControl of Bubble Formation at the Optical Fiber Tip by Analyzing Ultrasound Acoustic WavesViacheslav Viacheslavovich Kazakov, Vladimir Isaakovich Yusupov, Viktor Nikolaevich Bagratashvili et al.The problems of controlling the processes of generation of acoustic waves and microbubbles at the optical fiber tip of moderate-power surgical lasers with wavelengths of 1.9 µm and 0.97 µm using active and passive acoustic methods are considered. It is shown that microbubbles of various sizes can be detected with an ultrasound method, in which the interaction area is recorded … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,485 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetecting an Anomaly Behavior through Enhancing the Mechanism of Packet FilteringMohammed Nazeh Abdul Wahid, Azizol AbdullahThe fundamental task of the Network Traffic Analysis is the ability of capturing and monitoring all the network traffics (incoming and outgoing) for local area network LAN and how the network analyzer is able to analyze and detect errors or any type of suspicious activities such as intruders. The idea of this research is to use flexible packet filtering to … …Journal of Computer Science, Vol. 11, Issue 6 · 1 Sep 2015 · 6,950 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCAVITY SEGMENTATION AND STROKE VOLUME MEASUREMENT METHODS FROM ECHOCARDIOGRAPHIC IMAGES: REVIEWAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.The complexity and criticality of heart disease diagnosis and treatment have frequently attracted the attention of researchers to develop approaches that can handle accurate clinical assessments. One of these complexities is measuring the Right Ventricle stroke volume. Therefore, different cardiac imaging techniques have been developed to help specialists in their regular clinical work and in the operating theatre to assist … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,410 accessesView PDFCite
