Research ArticleOpen accessIn the abstractContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,791 accessesView PDFCite
Review ArticleOpen accessIn the abstractSargassum Invasion of Coastal Environments: A Growing ConcernClifford Louime, Jodany Fortune, Gary GervaisFloating tropical brown macroalgae, commonly called Sargassum, besieging the Caribbean coastlines have long been a regular occurrence in the region, especially during the fall and winter months. These washed-up seaweeds are considered by scientists as an important part of the coastal ecosystem, as they serve as habitat and nurseries for numerous marine species. However, in recent years, the region has … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 6 Feb 2017 · 12,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeobody Architecture and Petroleum Potential of the Yowi Field, Offshore Eastern Niger Delta, NigeriaPrince Suka Momta, Minapuye Isaac OdigiA study on geobody architecture and petroleum potential of the Yowi Field has been carried out by integrating well logs and 3D seismic data. The objectives of this study include: The determination of the lateral continuity of key horizons; identification of gross geobody distribution and architecture; and the petroleum potential of the field. Well log correlation shows that key horizons … …Current Research in Geoscience, Vol. 6, Issue 1 · 16 Dec 2015 · 7,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractMuon Anomalous Magnetic Moment in a SU(4) ⊗ U(1)N Model Without Exotic Electric ChargesDiego CogolloWe study an electroweak gauge extension of the standard model, so called 3-4-1 model, which does not contain exotic electric charges and it is anomaly free. We discuss phenomenological constraints of the model and compute all the corrections to the muon magnetic moment. Mainly, we discuss different mass regimes and their impact on this correction, deriving for the first time … …Physics International, Vol. 6, Issue 1 · 13 Sep 2015 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Model of Gauged Lepton and Baryon ChargesP.V. Dong, H.N. LongWe propose a simple extension of the standard model with lepton and baryon numbers gauged by introducing only two leptoquarks (j+1/2, k-1/2) to the fermion content. As natural consequences of the anomaly cancelation, the right-handed neutrinos present and the number of observed fermion families equals to the number of fundamental colors, which is three. To avoid stabilized colored-leptoquarks, two scalar … …Physics International, Vol. 6, Issue 1 · 20 Jun 2015 · 7,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractTissue Engineering of Articular Cartilage: A Mini-ReviewRadoslav Zamborsky, Jana Rusnakova, Andreas NicodemouDamage of articular cartilage due to congenital anomaly, injury or pathological process may lead in decreasing of life quality of affected patients. In many cases, conventional therapeutical approaches may not bring expected results. Tissue engineering by the combination of material technology and cell-based therapy may represent hope for these patients. The main goal of this review article is to summarize … …OnLine Journal of Biological Sciences, Vol. 14, Issue 4 · 5 Jan 2015 · 6,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractREVIEW CLUSTERING MECHANISMS OF DISTRIBUTED DENIAL OF SERVICE ATTACKSWesam Bhaya, Mehdi Ebady ManaaDistributed Denial of Service attacks (DDoS) overwhelm network resources with useless or harmful packets and prevent normal users from accessing these network resources. These attacks jeopardize the confidentiality, privacy and integrity of information on the internet. Since it is very difficult to set any predefined rules to correctly identify genuine network traffic, an anomaly-based Intrusion Detection System (IDS) for network … …Journal of Computer Science, Vol. 10, Issue 10 · 26 Jun 2014 · 7,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid of Fuzzy Clustering Neural Network Over NSL Dataset for Intrusion Detection SystemDahlia Asyiqin Ahmad Zainaddin, Zurina Mohd HanapiIntrusion Detection System (IDS) is one of the component that take part in the system defence, to identify abnormal activities happening in the computer system. Nowadays, IDS facing composite demands to defeat modern attack activities from damaging the computer systems. Anomaly-Based IDS examines ongoing traffic, activity, transactions and behavior in order to identify intrusions by detecting anomalies. These technique identifies … …Journal of Computer Science, Vol. 9, Issue 3 · 4 May 2013 · 6,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Aberrant Data Points for an effective Effort Estimation using an Enhanced Algorithm with Adaptive FeaturesS. Malathi, S. SridharProblem statement: The spiraling growth of IT industry has witnessed an unprecedented change in the software development paradigm, from algorithmic models to machine learning techniques. At present, there are no standard methods to predict the accuracy of software cost estimation, which is an important goal of the software community. Approach: This study proposes a simple and systematic algorithmic procedure for … …Journal of Computer Science, Vol. 8, Issue 2 · 21 Nov 2011 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality of Service Policy for IEEE 802.11 Networks with Service Rate Selection based on Fairness IndexLia Toledo Moreira Mota, Alexandre de Assis Mota, Luis Fernando FontolanProblem statement: The IEEE802.11 standard states that all stations have the same probability of accessing the network, but does not consider important parameters such as transmission rates and signal-to-noise ratios. However, these networks present an anomaly that allows a station with a low transmission rate to use the communication channel for a long time. Approach: In this context, this study … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,660 accessesView PDFCite
