Research ArticleOpen accessIn the keywordsAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmart Ambulances for IoT Based Accident Detection, Tracking and ResponseAmreen Ayesha, Komalavalli ChakravarthiOne of the main reasons for death among young people in the current era is based on road accidents. The goal of current research on accident detection systems is to shorten reporting times, increase accident detection accuracy and address them through our modern technology. Our primary goal is to recommend a system that can successfully aid in preventing any kind … …Journal of Computer Science, Vol. 19, Issue 6 · 12 May 2023 · 6,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn On-line Analytical Processing (OLAP) Aggregation Function for Rising Aspects in Collaboration and Social NetworksWaqas Nawaz, Kifayat Ullah Khan, Muhammad Shoaib SiddiquiThe overwhelming usage of social and collaboration networks provides the opportunity to analyze evolution of relationships among individuals, like celebrities or co-authors. Discovering such phenomenon in large complex networks is non-trivial due to their large sizes. In this situation, the aggregation functions used in OLAP, are useful to analyze the summarized data. OLAP has successfully proven its worth on multidimensional … …Journal of Computer Science, Vol. 16, Issue 6 · 10 Jun 2020 · 7,120 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Sequence and Frequency Hopping Signals Classification Based on Co-Occurrence Matrix and Clustering TechniquesHaidy S. Fouad, Hend A. Elsayed, Shawkat K. GirgisSpread Spectrum techniques (SS) were first developed for military applications, but currently, they have commercial applications. SS provides secure communication and allows multiple accesses for same radio spectrum. So, most Wireless Local Area Network (WLAN) systems use it, as do Cognitive Radios (CR), space systems and Global Positioning Systems (GPS). Direct Sequence Spread Spectrum (DSSS) and frequency hopped spread spectrum … …Journal of Computer Science, Vol. 15, Issue 1 · 10 Jan 2019 · 8,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method for Multipath Clustering for Over-the-Horizon RadarAshraf M. Aziz, Senior Member, IEEE et al.Over-the-Horizon Radar (OTHR) exploits the refraction of high frequency radiation through the ionosphere layers to detect targets beyond the line-of-sight horizon. Multipath propagation between the radar and the detected targets may results in multiple spatially separated tracks for a single target to be observed at the receiver site. Consequently there is a heavy traffic, especially in case of multiple targets, … …American Journal of Applied Sciences, Vol. 13, Issue 10 · 29 Sep 2016 · 7,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Optimal Incoherent Subcarrier Tracking of BOC(1,1) Navigation SignalsAlexandr Ivanovich PerovNavigation receivers of global positioning systems that are operated in complex electromagnetic environment must have an increased noise immunity characteristic. One way of such noise immunity rising is to use incoherent operating mode of navigation receiver. There are known processing algorithms for navigation signals with Binary Phase Shift Keying (BPSK) modulation. But in the near-term outlook Global Navigation Satellite Systems … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 26 Sep 2016 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the abstractGIS Mapping of Basal Stem Rot Disease in Relation to Soil Series Among Oil Palm SmallholdersK. Parthiban, R. Vanitah, K. Jusoff et al.Basal Stem Rot (BSR) is a disease caused by fungus which affect oil palm tree. This study aims to visualize the geographical distribution of BSR incidence among oil palm smallholders in Selangor using Geographical Information System (GIS) and its relationship to the type of soil series. The geographical distribution of BSR incidence of smallholders in Selangor were mapped using 168 … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 5 Jan 2016 · 8,683 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 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOBILE COMMUNICATIONS FOR USING IN TELEMEDICINEMarjan Ghazi Saeedi, Mashaallah Torabi, Sakineh Hamidi, Hassan RanjiTelemedicine the use of telecommunication and information technologies in order to provide clinical health care at a distance helps eliminate distance barriers and can improve access to medical services that would often not be consistently available in distant rural communities. It is also used to save lives in critical care and emergency situations. Although there were distant precursors to telemedicine, … …Current Research in Medicine, Vol. 5, Issue 1 · 12 Feb 2014 · 9,985 accessesView PDFCite
