Research ArticleOpen accessIn the abstractComprehensive Investigation into the Exergy Values of Six Rice HusksYaning Zhang, A.E. Ghaly, Bingxi LiExergy is a measurement of how far a certain system or material deviates from a state of equilibrium with the environment and it is a useful tool for improving the efficiency of energy-resource use. Based on the previous work, the exergy values of six rice husks were investigated in this study. The effects of physical and chemical properties were also … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 10 Jun 2013 · 7,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractRiver Flow Conditions and Dynamic State Analysis of Pahang RiverMuhamad Barzani Gasim, M. E. Toriman, Mushrifah Idris et al.Pahang River (Sg. Pahang) is the longest river in Peninsular Malaysia. Flood is a common event in Pahang River Basin during wet season which triggered by monsoon season. The hydrodynamic study of Pahang River should be well understood especially when it is a target of northeast monsoon which influenced the Pahang River Basin every year (from November to March). 17 … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 10 Jan 2013 · 8,709 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of 137Cs Activity to Investigate Sediment Movement and Transport Modeling in River Coastal EnvironmentM. E. Toriman, Muhamad Barzani Gasim, Zulkifli Yusop et al.Conflicts between human and environment always triggered to sedimentation and erosion problems within the coastal areas, Therefore understanding sediment transport processes in a river estuary and coastal waters was important when studying sediment transport and mobility within the river coastal environment. This article aims to investigate the sediment transport and mobility of the Kemaman River estuary, Terengganu Malaysia. In this … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 22 Jun 2012 · 7,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Channel Estimation for Multiuser Underwater Communication SystemsS. Aliesawi, C. C. Tsimenidis, B. S. Sharif, M. JohnstonProblem statement: Multiple Access Interference (MAI) signals and poor estimation of the unknown channel parameters in the presence of limited training sequences are two of the major problems that degrade the systems’ performance. Two synchronous multiuser receivers with Rake reception of Interleave Division Multiple Access (IDMA) and Code Division Multiple Access (CDMA) systems, in conjunction with channel estimation, are considered … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 20 Feb 2012 · 7,358 accessesView PDFCite
Research ArticleOpen accessIn the abstractProposed Reliability Techniques on Soil and Rock ExcavationsS. TangchawalProblem statement: Assessment of the ground mass excavation is normally done by the deterministic method. A quantitative indication of mass stability provides as an index term known "the Factor of Safety (F.S.)". There are uncertain to some degrees, such as only a single value of mass properties is used or variation in geologic conditions, computed values of F.S. are never … …Energy Research Journal, Vol. 2, Issue 1 · 26 Jan 2012 · 7,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Pollutant Diesel Fuels on Neurobehavioral Performance among Workers in Locomotive DepotAnuar Ithnin, Radiah Abu Hasan Shaari, Mazrura Sahani et al.Problem statement: Diesel fuel contains various combinations of hydrocarbons such as cyclohexane, n-hexane, benzene and toluene which can cause health problems in major exposure of that pollutant in locomotive depots. Studies were conducted to evaluate the exposure towards diesel fuel pollutant and the effect on neurobehavioral performances among workers in locomotive depots. Approach: Method used was questionnaire form and neurobehavioral … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Soil Moisture Sensors under Intelligent Irrigation Systems for Economical Crops in Arid RegionsMohamed Said Abdall El Marazky, Fawzi Said Mohammad, Hussein Mohamed Al-GhobariProblem Statement: In irrigation water management, irrigation water use represents a substantial opportunity for agriculture water savings. Automation of irrigation systems, based on Soil Moisture Sensors Systems (SMSS) has the potential to provide maximum water use efficiency by maintaining soil moisture at optimum levels.
