Research ArticleOpen accessIn the abstractDevelopment of Fuzzy Controller for Water Level in Stream Boiler TankSurachai PanichProblem statement: The process control of steam boiler is very popular used in the industrial. The temperature of the water is transferred directly by electrical heater. The pressure will increase based on the changing of the temperature. The purpose of the control is to change the opening set point for the valve when the temperature and pressure in the tank … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 8,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Permeability of Foam Conditioned Soils with Laboratory TestsLuca Borio, Daniele PeilaProblem statement: EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face. The evaluation of this parameter in granular soil, before and after conditioning, is therefore of key importance … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,468 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractPore Water Pressure Contribution to Debris Flow MobilityChiara DeangeliProblem statement: Debris flows are very to extremely rapid flows of saturated granular soils. Two main types of debris flow are generally recognized: Open slope debris flows and channelized debris flows. The former is the results of some form of slope failures, the latter can develop along preexisting stream courses by the mobilization of previously deposited debris blanket. The problem … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydraulic Characteristics and Pore Water Flow Rule in Constant Rate of Strain ConsolidationA. Ahmadi, A. H. Hoorfar, H. Rahimi, A. SoroushProblem statement: At present study Constant Rate of Strain (CRS) consolidation under Non-Darcy condition was investigated. Approach: In this study a governing conditions on pore water flow were investigated using proposed equation and experimental tests. CRS experiments under different rates of strain were conducted on different soil samples. Results: Results of these experiments and there comparison with proposed equation showed … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractBentonite used as Adsorbent Agent of the Coupling Adsorption Ultrafiltration of the Secondary Effluents for their ReuseD. Abdessemed, G. NezzalThis present study has for principal objective to treat secondary effluents of the Staoueli purification plant (Algeria) with the average characteristics in the Chemical Oxygen Demand (COD) is 76 mg L-1and 16 NTU of turbidity by adsorption ultrafiltration coupling for its reuse in irrigation or in industry to reduce the water demand. A mineral ultrafiltration tubular membrane of CARBOSEP M2 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractEngineering Properties and Compressibility Behavior of Tropical Peat SoilYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the engineering properties and compressibility behavior of various types of tropical peat soil collected from several locations in Malaysia. These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. The correlations of the various basic engineering properties of the tropical peat soils have been found to be close … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling MudOlaitan Oluwaseum Micheal, Orodu Oyinkepreye David, Ehinmowo Adegboyega BoluThe use of emulsion drilling mud in the oil and gas industry has gained wide acceptance. However, the disposal of drill cuttings and the waste of such emulsion drilling mud usually poses environmental concern. Hence, there is the need to seek oil from biodegradable sources as an alternative to the current conventional diesel oil which constitute environmental threat. In this … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Jun 2017 · 7,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractDissolution Sintering Technique to Create Porous Copper with Sodium Chloride Using Polyvinyl Alcohol Solution through Powder MetallurgyCynthia Waters, Stephen Ajinola, Mustafa SalihThe main purpose of this paper was to investigate the relative densities, porosities, compression strength and energy absorbed by porous copper (Cu) formed via the dissolution sintering technique using Polyvinyl Alcohol (PVA) solution as a binder with Sodium Chloride (NaCl) as space holder. Porous Cu was fabricated through powder metallurgy route using dissolution sintering technique by mixing Cu with NaCl … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,990 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling of Stress- Strain Curves of Drained Triaxial Test on SandAwad Al- Karni, Abdulhafiz AlshenawyThis paper presents a hyperbolic mathematical model to predict the complete stress-strain curve of drained triaxial tests on uniform dense sand. The model was formed in one equation with many parameters. The main parameters that are needed to run the model are the confining pressure, angle of friction and the relative density. The other parameters, initial and final slopes of … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 6,845 accessesView PDFCite
