Research ArticleOpen accessPhrase in the titleUSING LIGHT TO SEE NEUTRONS AND ACCESSING THE 2D HIGH RESOLUTION: BAROTRON: A NEW PULSE FOR NEUTRON SCATTERINGPatrick Baroni, Laurence NoirezSince first years of exploitation in 1960-70, neutron scattering has emerged as a unique and non-destructive means to probing inside matter properties at the nanometer length scales. Because the neutron production is scarce and expensive, the detection has to be extremely efficient. We take advantage of the recent improvements of light sensors in photon detection and detection dynamics, to develop … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 7,077 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleHigh Resolution Satellite Images to Reconstruct Recent Evolution of Domitian CoastlinePasquale Maglione, Claudio Parente, Andrea VallarioIn the last decades, combinations of natural and humanfactors have resulted in extensive morphological changes to our coastlines andin many cases have amplified erosion. In order to limit these changes and theirimpact on coastal zone, it is important toplan specific actions; for this purpose detailed cognizance of coastal zone isnecessary. Different and heterogeneous data such as historical and recent maps,remotely … …American Journal of Applied Sciences, Vol. 12, Issue 7 · 28 Aug 2015 · 7,011 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleCurie 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 · 7,811 accessesView PDF Cite

Review ArticleOpen accessPhrase in the titleVery 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 PDF Cite

Research ArticleOpen accessPhrase in the titleOn-Chip Implementation of High Resolution High Speed Floating Point Adder/Subtractor with Reducing Mean Latency for OFDMRozita Teymourzadeh, Yazan Samir Algnabi, Nooshin Mahdavi, Masuri Bin OthmanProblem statement: Fast Fourier Transform (FFT) is widely applied in OFDM trance-receiver communications system. Hence efficient FFT algorithm is always considered. Approach: This study proposed FPGA realization of high resolution high speed low latency floating point adder/subtractor for FFT in OFDM trance-receiver. The design was implemented for 32 bit pipelined adder/subtractor which satisfied IEEE-754 standard for floating-point arithmetic. The design … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,924 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleAssessment of Geothermal Energy Potential of Ruwan Zafi, Adamawa State and Environs, Northeastern Nigeria, using High Resolution Airborne Magnetic DataIbe Stephen Onyejiuwaka, Uche Kelvin IdumaThe aeromagnetic dataset over Ruwan Zafi, Adamawa State and environs, Northeastern Nigeria, was interpreted in this study, in order to map out places with the potentials for application of geothermal energy for electricity generation and geothermal direct heating. The analysis of the spectral of the magnetic dataset delineated the range of the sediment thickness as 4273.58 and 8693.32 m and … …Current Research in Geoscience, Vol. 10, Issue 1 · 4 Dec 2020 · 12,352 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEvaluation of Polymorphisms at Heat Shock Protein 90 Gene by High Resolution Melting Assays for Potential Heat Tolerance among Nigerian Zebu Cattle BreedsGbolabo Onasanya, George Msalya, Aranganoor Thiruvenkadan et al.Heat Shock Protein (HSP) 90 gene is a member of HSPs sub-family that act as molecular chaperons whenever animals come under thermal stress. The genes fulfill essential roles of providing cellular protection, immune response, protein synthesis, protein folding and unfolding, protection from cellular stress, inhibitory apoptosis and adaptation. This study was designed to analyze polymorphisms of HSP 90 and to … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 1 · 7 Mar 2020 · 7,258 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Extract Region of Interest in High-Resolution Palmprint using 2D Image Histogram Entropy FunctionInass Shahadha Hussein, Shamsul Bin Sahibuddin, Md Jan Nordin, Nilam Nur AmirThe segmentation of high-resolution palmprint is has been challenged and the research in this filed is still limited because of variations in location and distortion of these images. To achieve superior recognition result, accurate segmentation of a region of interest is very crucial. Therefore, in this paper, a novel palmprint extraction method has been presented using a 2D image histogram … …Journal of Computer Science, Vol. 15, Issue 5 · 8 May 2019 · 7,652 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAnalytical Study of High Pitch Delay Resolution Technique for Tonal Speech CodingSuphattharachai Chomphan, Chutarat ChompunthProblem statement: In tonal-language speech, since tone plays important role not only on the naturalness and also the intelligibility of the speech, it must be treated appropriately in a speech coder algorithm.
