Research ArticleOpen accessEvery word in the titleTime Dimension Parameters of the Dual-Porosity Reservoir Determination using Periodic Hydraulic Pulse TestingMarat Ovchinnikov, Kushtanova Galiya GatinishnaThe process of periodic hydraulic pulses propagation in porous fractured media of dual-porosity near a vertical well is considered. Using the calculation data as the base, it is shown that the effect of the time dimension constant on the form of the filtration wave curves is essential. The conclusions on possibility of hydrodynamic model types verification which adequately describe the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 9 Sep 2016 · 6,991 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Vibration Analysis of Diesel Engine with Hydrogen-Diesel Dual FuelBoonthum Wongchai, Porranat Visuwan, Sathaporn ChuepengThe diesel engine vibration is one of the main problems of engine damage. When the hydrogen-diesel dual fuel is used, it may affect the engine vibration. Therefore, it is necessary to study the effect of hydrogen-diesel dual fuel. The regression analysis is used to find the relations between hydrogen percentage and the engine vibration. The results for all cases found … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 2 Jan 2013 · 7,898 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Performance of a Dual Header Pulse Interval Modulation in the Presence of Artificial Light Interferences in an Indoor Optical Wireless Communications Channel with Wavelet DenoisingS. Rajbhandari, Z. Ghassemlooy, M. AngelovaProblem statement: Similar to other baseband modulation schemes, the performance of the Dual Header Pulse Interval Modulation (DH-PIM) is adversely affected by Artificial Light Interferences (ALI) in an indoor Optical Wireless Communications (OWC) channel. Approach: The Discrete Wavelet Transform (DWT) based denoising is studied for reducing the effect of the ALI. Computer simulation is carried out to demonstrate the effectiveness … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 7,780 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,542 accessesView PDFCite
