Research ArticleOpen accessIn the abstractWorking Process Analysis and Parameter Optimization of Millet Hill-Drop Seed Metering DeviceTao Chen, Shujuan Yi, Yifei LiDue to the small size, light weight, and impurities of millet, the existing seeders have poor quality when sowing millet, this study analyzed the working process of the pneumatic-mechanical combined seed metering device, established the equations of seed movement in the seed filling zone, seed cleaning up zone, seed carrying zone and seed dropping zone by dynamic theory. The theoretical … …American Journal of Agricultural and Biological Sciences, Vol. 18, Issue 1 · 12 Aug 2023 · 6,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Logic-Based Smart Traffic Management SystemsAdel Abdallah Abdou, Mohamed Hassan Farrag, A. S. TolbaTraffic congestion is a serious problem in many developing countrieslike Egypt. In the presence of thetraditional traffic light system, it creates health risks, wastes time andfuel, and pollutes the air. Therefore, there is a big need for a smart trafficmanagement system. This study contributes in solving this problem byintroducing an artificial intelligence-based smart traffic light system usingfuzzy logic to ensure … …Journal of Computer Science, Vol. 18, Issue 11 · 24 Nov 2022 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeaching of a Nigerian Refractory Gold Ore Using Aqua RegiaOluwasanmi Samuel Teniola, Abraham A. Adeleke, Simeon Ademola Ibitoye, Moshood Deinde ShituIn this research, refractory gold ore from Imogbara deposit in Iperindo area of Osun state Nigeria were collected systematically from various segments of the deposits at different depths to obtain a set of samples that truly represent the deposits. The 50 kg sample collected was subjected to panning in a flowing river to obtain about 1 kg-upgraded sample. The upgraded … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 13 Mar 2022 · 7,457 accessesView PDFCite
Review ArticleOpen accessIn the abstractAn Exoplanet has Smothering Stratosphere without WaterRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIn some earlier works, the authors of the present study have shown that a modern ship should resemble a UFO, an accelerated particle jet propulsion with a particle accelerator on board the ship, accelerating to the very best big. The problem as an idea is clear and simple, but the current technologies we have in the field of fixed particle … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 6,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Physics: Emergent Unified Dynamical 3-Space, Quantum and Gravity: A ReviewReginald Thomas CahillExperiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec-1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the beginning of physics. This dynamical space generates a … …Physics International, Vol. 6, Issue 2 · 4 Aug 2015 · 8,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Impact of Darkness on Highway Traffic Shockwave PropagationParameswary Sundara, Othman Che Puan, Mohammad Rosli HaininDuring darkness visibility diminishes resulting in reduced sight distances and drivers are subjected to anxiety that may give way to anger and frustration. However, the study is concerned with traffic shockwave propagation that could be associated with darkness on highways. Based on the hypothesis that darkness may induce temporary traffic shockwave propagation in the presence of substantial traffic volume, darkness … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmission Factors of CH4 and CO2 Emitted from VehiclesSutthicha Nilrit, Pantawat Sampanpanish, Surat BualertThe study of the Emission Factors (EF) of methane (CH4) and Carbon Dioxide (CO2) emitted from vehicle exhaust is the study of greenhouse gases that are crucial to climate change. These gases are part of a fuel known as Compressed Natural Gas (CNG) or as Natural Gas for Vehicles (NGV) in Thailand. This fuel is used as an alternative to … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 29 Jan 2013 · 8,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Survey on Joint Compression and Encryption Techniques for Video DataK. John Singh, R. ManimegalaiProblem statement: When we send any video data over the network it consumes more time. This is due to the huge size of the video file when compared to text file. Therefore, video data should be compressed before sending to the destination. Another important factor during data transfer is security. Joint compression and encryption is employed to enable faster and … …Journal of Computer Science, Vol. 8, Issue 5 · 28 Feb 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractShear Bond Strength of Four Cariostatic Tooth Colored Materials to Dentin of Permanent Premolar TeethE. Farrokhgisu, A. EskandarizadeProblem statement: The purpose of this study was to compare the shear bond strength of four cariostatic restorative materials to dentin of permanent teeth. Approach: Restorative materials which have used in the study were composite P60 (3M), conventional glass ionomer (Fuji II, GC), light cured glass ionomer (Vitremer, 3M), compomer (F2000, 3M) and flow compoglass (Vivadent). This study was in … …Current Research in Dentistry, Vol. 1, Issue 2 · 16 Jul 2011 · 8,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost-Effective Fabrication of Self-Made 1×12 Polymer Optical Fiber-Based Optical Splitters for Automotive ApplicationMohammad Syuhaimi Ab-Rahman, Hadi Guna, Mohd Hazwan Harun et al.Problem statement: Multimode fiber cables can conduct many light rays and can operate free of disruption and with a greater bandwidth than a wireless connection. However, due to a slight variation in the speed of the light rays through the multimode fiber, a signal transmitted by all of these rays becomes spread out. Consequently, the signals become broader and therefore … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,925 accessesView PDFCite
