Research ArticleOpen accessIn the abstractA Robust Recognition System for Pecan Weevil using Artificial Neural NetworksSaleh Mufleh Al-SaqerProblem statement: Pecan Weevil is a widely found pest among pecan trees and these pests are known to cause significant damage to the pecan trees resulting in enormous annual losses to pecan growers. Traditional identification techniques for pecan weevil include traps with pheromones to detect the infestation of these pests. However, these traditional methods require expensive labor hours to set-up … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 6,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Reliable Identification System for Red Palm WeevilSaleh Mufleh Al-SaqerProblem statement: Red Palm Weevil (RPW) is a widely found pest among palm trees and is known to cause significant losses every year to palm growers. Existing identification techniques for RPW comprise of using traps with pheromones to detect these pests. However, these traditional methods are labor-intensive, expensive to implement and unreliable for early detection of RPW infestation. Early detection … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 18 Jun 2012 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Anaerobic Fermentation of Simple Sugars by Yeast Fuels Resistance Candida spp. Infections to Eradication by DrugsNedosa Ikenna Valentine, Utoh-Nedosa Uchechukwu Anastasia, Dan Danjuma et al.Problem statement: Human systemic Candida infections had proved difficult to eradicate by the medical health care system. Some practitioners and scholars see the problem as being due to drug resistance. For example an author wrote that ‘secondary drug resistance is clearly being encountered in one setting, oropharyngeal candidiasis in patients with advanced Human Immunodeficiency Virus type 1 (HIV-1) infection usually … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 10 Dec 2011 · 7,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractPositron Annihilation Study on Nickel and Iron Nano-Particles in Natural Rubber CompositesEmad Hassan AlyProblem statement: The effect of Ni and Fe nano-particles as a filler on the free volume properties Of Natural Rubber (NR) was studied using Positron Annihilation Lifetime Spectroscopy (PALS). Approach: The PAL measurements revealed that the free volume properties are strongly affected by the amount and type of filler. Results: Particularly speaking, the free volume fraction dramatically decreased by increasing … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Parametric Deduction for Material Removal Rate OptimizationTian-Syung LanProblem statement: A general optimization scheme without equipment operations for CNC (computer numerical control) finish turning is deemed to be necessarily developed. Approach: In this study, four parameters (cutting depth, feed rate, speed, tool nose runoff) with three levels (low, medium, high) were considered to optimize the Material Removal Rate (MRR) based on L9(34) orthogonal array. Twenty-seven fuzzy control rules … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractFreezing and Thawing Durability of Very High Strength ConcreteSameer Hamoush, Miguel Picornell-Darder, Taher Abu-Lebdeh, Ahmed MohamedProblem statement: The newly developed Very High Strength Concrete (VHSC), having compressive strengths of 29 ksi and flexural strengths of 6 ksi, represents a breakthrough in concrete technology. Study to further enhance the properties of this new concrete is continuing. Approach: The objective of this study is to investigate the effect of exposing Very High Strength Concrete (VHSC) specimens to … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 8,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractParametric Deduction Optimization for Surface RoughnessTian-Syung LanProblem statement: Surface roughness is a major consideration in modern Computer Numerical Control (CNC) turning industry. Most existing optimization researches for CNC finish turning were either accomplished within certain manufacturing circumstances, or achieved through numerous equipment operations. Therefore, a general deduction optimization scheme is deemed to be necessary for the industry. Approach: In this study, four parameters (cutting depth, feed … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Total Ionizing Dose on Bipolar Junction TransistorChee Fuei Pien, Haider F. Abdul Amir, Saafie Salleh, Azali MuhammadProblem statement: The amount of ionizing radiation that Bipolar Junction Transistor (BJT) devices encounter during their lifecycle degrades both of their functional and electrical parameter performances. The different radiation environments either in space, high energy physics experiments, nuclear environment or fabrication process as well as for standard terrestrial operation possess an impact on the devices. Approach: In this research, analytical … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,311 accessesView PDFCite
