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
Research ArticleOpen accessIn the abstractQoS Based IPTV over LTE-WLAN Heterogeneous NetworksMohamed Matoui, Noureddine Moumkine, Abdellah AdibHeterogeneous networks required IP Multimedia Subsystem (IMS) technologies to perform their control signaling and improve their communication services. However, the highest IPTV-QoS cannot be performed using IMS only as it cannot differentiate between IPTV video components. In this paper, we implement our IPTV-flow label technique in LTE-WLAN heterogeneous systems that used to improve QoS by providing IPTV sub traffic priority … …Journal of Computer Science, Vol. 15, Issue 4 · 19 Apr 2019 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Optimization of Physics Simulations Through Genetic AlgorithmsOksana Shadura, Federico Carminati, Anatoliy PetrenkoThe GeantV R&D approach is revisiting the standard particle transport simulation approach to be able to benefit from “Single Instruction, Multiple Data” (SIMD) computational architectures or extremely parallel systems like coprocessors and GPUs. The goal of this work is to develop a mechanism for optimizing the programs used for High-Energy Physics (HEP) particle transport simulations using a “black-box” optimization approach. … …Journal of Computer Science, Vol. 15, Issue 1 · 8 Jan 2019 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom Structural Colors to Super-Hydrophobicity and Achromatic Transparent Protective Coatings: Ion Plating Plasma Assisted TiO2 and SiO2 Nano-Film DepositionRaffaella Aversa, Valeria Perrotta, Relly Victoria V. Petrescu et al.The implementation of the Ion Plating Plasma Assisted technology in the area of surface functionalization for structural color and relic preservation applications is presented. Interferometric structural colors on irregular bumped Titanium surfaces and transparent and achromatic nano films on ancient ceramic artifact have been investigated. Titanium metal and ceramic supports have been utilized for the surface functionalization tests: A metallic … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 24 Nov 2016 · 8,459 accessesView PDFCite
Review ArticleOpen accessIn the abstractVery High Resolution Optical Satellites: An Overview of the Most Commonly usedPasquale MaglioneVery High Resolution (VHR) satellite systems are platforms whose sensors acquire high geometric resolution images. Since 1972, when the first satellite was launched (Land sat ERTS), the spatial resolution of the satellite image has increased, making Ground Sample Distance (GSD) reaching 0.30 m at Nadir in panchromatic images. In this paper, after a brief introduction, concepts relative to orbits, types … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 25 Jan 2016 · 9,059 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital High-Pass Filters with Milder High-Pass Effect on Digital ImagesIssa A. Al-ShakhrahImage filtering consists of modifying the original image by logically "reimaging" it with a mathematical imaging device in which spatial response can be controlled by the user. Image filtering is performed by a mathematical operation called convolution, which is simply the successive replacement of each point in the original image by a new value produced by a weighted combination of … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 11 Jun 2015 · 7,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeterminants of Non-farm Income Diversification in Developed Villages of BangladeshMohammad Abdul Malek, Koichi UsamiProblem statement: Though the Non-Farm Sector (NFS) has been prioritized in the national policy documents, empirical evidences based on the broader definition of the sector seem to be insufficient about its role both in income diversification and income distribution especially in segmented area of rural Bangladesh. Approach: We use income inequality Gini decomposition method for exploring the role of Non-Farm … …American Journal of Economics and Business Administration, Vol. 1, Issue 2 · 30 Jun 2009 · 8,356 accessesView PDFCite
Review ArticleOpen accessIn the abstractA New Exoplanet Reveals its IdentityNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuPositioned approximately 70 light years from Earth a sun named by astronomer HD 97658, is nearly bright enough to be seen even with the naked eye. The more interesting part of the problem lies in the fact that this sun, this star, also has an exoplanet HD 97658b, the size of which is approximately double compared to our planet Earth … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 5 Jun 2018 · 7,495 accessesView PDFCite
Review ArticleOpen accessIn the abstractAdaptive Video Quality Model for UHD Video Broadcasting Using the Principle of InclusionUrvashi Pal, Horace KingIn this study, an adaptive video quality algorithm is developed for Ultra High Definition (UHD) video broadcasting through Digital Video Broadcasting by Satellite 2nd Generation (DVB-S2), where three conditions are responsible for enhancing or reducing the quality of a video signal received by the DVB-S2 Set-Top-Box (STB). The conditions are: Coverage area, Distance between transmitter and receiver and Separation distance. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 20 Nov 2017 · 7,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomimetic Finite Element Analysis Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentAversa Raffaella, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Apicella AntonioThe human femur shows a high capacity to withstand external stresses and it is due to the mass distribution, morphology, and orthotropic behaviors of trabecular and cortical bone. Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. The use of biofidel model is aimed to develop an "in silico" tool that could enable the … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 30 Nov 2016 · 8,980 accessesView PDFCite
