Research ArticleOpen accessIn the abstractLeafsnapNet: An Experimentally Evolved Deep Learning Model for Recognition of Plant Species based on Leafsnap Image DatasetEmmanuel Adetiba et al.Plants are very important living organisms on earth because humans and animals depend on them for nutrition, oxygen, medicine and balance in the ecosystem. Therefore, plant species recognition is critical to the improvement of agricultural productivity, mitigation of climate change and the discovery of new medicinal plants. However, species recognition has remained a difficult task even for trained botanists, because … …Journal of Computer Science, Vol. 17, Issue 3 · 1 Apr 2021 · 7,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Strength Development in Stabilized Soil with CBR Plus and Silica SandSeyedesmaeil Mousavi, Aliakbar KaramvandThis paper investigates the potential use of a nano polymer stabilizer, namely CBR PLUS for stabilization of soft clay and formulation of an optimal mix design of stabilized soil with CBR PLUS and silica sand. The highway settlements induced by the soft clay are problematic due to serious damages in the form of cracks and deformation. With respect to this, … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 12 Apr 2017 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurie Point Depth (CPD) Investigation Of Offshore Niger Delta Using High Resolution Aeromagnetic DataOfoha Chimezie Charles, Emujakporue Godwin OmokenuOffshore Niger Delta, Nigeria, is known to be a hub for hydrocarbon exploration within the West Africa region and the world in general. The geologic settings within the Niger Delta province have a proven potential to assist in oil and gas exploration. However, much of the offshore provinces potential remains unknown with respect to the temperature differences using aeromagnetic data. … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Circulation in the Malacca Strait and Andaman Sea: A Numerical Model StudySyamsul Rizal, Peter Damm, Mulyadi A. Wahid et al.In the Andaman Sea and Malacca Strait, as in other parts of the Indian Ocean, the seasonal change of the wind plays a most important role: the south-west (hereafter SW) is monsoon active from June through September and the north-east (hereafter NE) monsoon is active from December through February. During the NE monsoon the winds are directed from the north … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 11 Aug 2012 · 18,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlbian-Cenomanian Zonation (Foraminifers and Calcareous Aglae) in the Northern Fars, IranMahnaz Parvaneh Nejad ShiraziProblem statement: In the middle Cretaceous of Iran, fossil calcareous algae and zonation them with foraminifers are one of the less studied compared to others invertebrate groups such as foraminiferis, mollusks and others. Several stratigraphic units were analyzed in detail and a biostratigraphic zonation of the Albian-Cenomanian rocks of the Fars basin (Sw. Iran) is proposed. Approach: All stratigraphic units … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractLiquefaction Susceptibility in the Northern Provinces of ThailandSupot Teachavorasinskun, Pichai Pattararattanakul, Pulpong PongvithayapranuProblem statement: There are quite a few active faults recently found in the western and northern parts of Thailand, which could possibly induce earthquakes of magnitude (ML) of 5.5-6.5. Although seismic design code has been enforced in the area since 1980, the fundamental knowledge on dynamic soil behavior has not been extensively attained. Approach: Collection of existing borehole information in … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on Suction-rainfall Response of a Cut Slope in Unsaturated Residual Soil Using a Field Rain SimulatorBujang B.K. Huat, Faisal Hj. Ali, S. MariappanThis research describes the design and construction of an artificial rain simulator system and the results obtained with regards to suction-rainfall response of a cut slope in unsaturated residual soil of weathered sandstone of various weathering grades. From the field measurements, the shallow tensiometers are found to record an immediate initial increase in matric suction within the first 20 min … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,278 accessesView PDFCite
Research ArticleOpen accessIn the abstractSequence Stratigraphic Analysis from Well Logs of an X-Field, Niger Delta, NigeriaGodwin Omokenu Emujakporue, Alphonsus Joseph EyoThe sequence stratigraphic analysis of the area was studied using well log information in order to determine the lithostratigraphy, chronostratigraphy, possible reservoir sands, age and depositional environment of the study area for opportunities that will support exploration program. The depositional environment penetrated by the wells interpreted from log signatures gave three major facies association. The blocky and coarsening upward (funnel … …Current Research in Geoscience, Vol. 6, Issue 2 · 11 Jul 2016 · 13,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Tunnel Face Stability through a Ground Stress Analysis with a Hemispherical Geometry ApproximationPierpaolo OresteThe evaluation of the stability of the excavation face is an important aspect in the design of a tunnel. When it is not possible to ensure excavation face stability in natural conditions, it is in fact necessary to intervene with remarkably costly reinforcement operations. The analysis of the stability conditions of an excavation face can be conducted, with a certain … …American Journal of Applied Sciences, Vol. 11, Issue 12 · 8 Jan 2015 · 6,730 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEEP TRAPS SPECTRA IN UNDOPED GAN FILMS GROWN BY HYDRIDE VAPOR PHASE EPITAXY UNDER VARIOUS CONDITIONSA. Y. Polyakov, N. B. Smirnov, A. V. Govorkov et al.Decreasing the residual donors density and deep traps spectra densities in undoped GaN films grown by Hydride Vapor Phase Epitaxy (HVPE) is very important for promoting the use of such material in high-voltage/high-power rectifiers, radiation detectors. In this study we studied the effects of changing the growth temperature of undoped HVPE GaN films on these properties. The two groups of … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,906 accessesView PDFCite
