BharanichandarThe invention is an effort to utilize the advantages offered by renewable resources for the development of composite materials based on polymer and particles of natural fibers for Conservation of natural resources. In this research, natural fibers like Sisal (Agave sisalana), Banana (Musa sepientum) and Roselle (Hibiscus sabdariffa), Sisal and banana (hybrid), Roselle and banana (hybrid) and Roselle and sisal … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 17 Jan 2014 · 17,331 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethodical Tuning of Proportional Plus Integral Controllers for Cascade Control of Separately Excited DC MotorsIbrahim Al-AbbasThe cascade control of DC motors by PI controllers was extensively used in industry. Approximation rules based on plotting the output of the system or on computer simulation were used to determine the parameters of these controllers. This study was done to develop mathematical expressions to calculate the parameters of these controllers. Output time functions of the system and there … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 12 Sep 2012 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractSessile Drop Evaporation and Leidenfrost PhenomenonA. K. Mozumder, M. R. Ullah, A. Hossain, M. A. IslamProblem statement: Quenching and cooling are important process in manufacturing industry for controlling the mechanical properties of materials, where evaporation is a vital mode of heat transfer. Approach: This study experimentally investigated the evaporation of sessile drop for four different heated surfaces of Aluminum, Brass, Copper and Mild steel with a combination of four different liquids as Methanol, Ethanol, Water … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Reliability and Productivity of an Aluminum Extruder by Implementation of Direct Torque Control TechnologyMazouz A. SalahatProblem statement: The linear motor drive is widely used in driving an extrusion puller in an aluminum extrusion industry. The main disadvantage of this drive is manual and step-wise torque control. This research was done to replace the linear motor drive by AC drive with direct torque control technology. Approach: Mathematical calculations were carried to select an AC drive which … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractOil Palm Biomass As Potential Substitution Raw Materials For Commercial Biomass Briquettes ProductionA.B. Nasrin, A.N. Ma, Y.M. Choo et al.Palm oil industry generates vast amount of palm biomass. Converting palm biomass into a uniform and solid fuel through briquetting process appears to be an attractive solution in upgrading its properties and add value. In this study, raw materials including empty fruit bunch (EFB), in powder and fibre forms, palm kernel expeller (PKE) and sawdust were densified into briquettes at … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 9,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Prototype Automated Sorting System for Plastic RecyclingD. A. Wahab, A. Hussain, E. Scavino et al.Automated sorting for plastic recyclables has been seen as the way forward in the plastic recycling industry. Automated sorting provides significant improvements in terms of efficiency and consistency in the sorting process. In the case of macro sorting, which is the most common type of automated sorting, efficiency is determined by the mechanical details of the material handling system as … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 8,824 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFabrication and Mechanical Properties of Glass Fiber/Talc/CaCO3 Filled Recycled PP CompositesUğur Soy, Fehim Findik, Salih Hakan Yetgin et al.Until now, recycling studies brought to the agenda after the rapid increasing of plastic materials in every area and causing those plastics to environmental pollution after discarding them following the utilization. The purpose of recycling plastic waste is to minimize environmental pollution and to create of new resources. To perform the present study, Recycled Polypropylene Granules (RPP) belonging to Polypropylene … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 15 Aug 2017 · 9,364 accessesView PDFCite
