Research ArticleOpen accessEvery word in the titleComparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode Laser-Pumped Nd:YAG Laser at 532 nmPrayut Potirak, Monludee Ranusawud, Pichet Limsuwan, Prathan BuranasiriAn iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 26 May 2018 · 7,891 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of UPFC-Based Stabilizer and PSS Performances on Damping of Power System OscillationsM. R. Meshkatoddini, M. Majidi, M. Sadeghierad, H. LesaniThis paper establishes the linearized Phillips-Heffron model of a power system equipped with UPFC and demonstrates the application of the model in analyzing the damping effect of the UPFC and designing UPFC based stabilizer to improve power system oscillation stability. A comprehensive approach to the design of UPFC based stabilizer (power flow control, DC-voltage regulator and damping controller) is presented. … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 6,455 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment 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 accessEvery word in the titleEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,704 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,459 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEco-Friendly Synthesis of Fucoidan-Stabilized Gold NanoparticlesKriengsak Lirdprapamongkol, Warangkana Warisnoicharoen, Suwicha Soisuwan, Jisnuson SvastiProblem statement: Metallic gold nanoparticles (AuNPs) are widely used in many applications including medical, pharmaceutical, diagnostics and sensors. The chemical synthesis of AuNPs normally requires synthetic materials which might cause the toxicological concerns. The use of naturally occurring materials like fucoidans for successful synthesis of AuNPs is of interests. Approach: Fucoidans as sulfated polysaccharides from marine algae Cladosiphon okamuranus (o-fucoidan) … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,630 accessesView PDFCite
