Research ArticleOpen accessIn the abstractA Modified Partially Mapped MultiCrossover Genetic Algorithm for Two-Dimensional Bin Packing ProblemM. Sarabian, L.S. LeeProblem statement: Non-oriented case of Two-Dimensional Rectangular Bin Packing Problem (2DRBPP) was studied in this study. The objective of this problem was to pack a given set of small rectangles, which may be rotated by 90°, without overlaps into a minimum numbers of identical large rectangles. Our aim was to improve the performance of the MultiCrossover Genetic Algorithm (MXGA) proposed … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 8,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractDairy Heifer Rearing in Hot Arid Zone: An Economic AssessmentM. A. Razzaque, S. A. Mohammed, T. Al-MutawaProblem statement: Economic losses due to high mortality in young calves born in hot arid zone including Kuwait and a high cost of rearing are the main constraints to this region. Therefore, dairy producers have to depend on importation of pregnant heifers for herd replacement. Research data on cost of heifer rearing from their weaning to first lactation were lacking. … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential, Implications and Solutions Regarding the Use of Rendered Animal Fats in AquafeedsJesse T. Trushenski, Rebecca T. LochmannProblem statement: In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 13,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Pre-Weaned Dairy Calves under Hot Arid Environment: Effects of Immunoglobulins and Age on Diseases and MortalityM. A. Razzaque, T. Al-Mutawa, S. Abbas, M. BedairProblem statement: A high mortality rate (crude mortality 43.6%) of pre-weaned dairy calves resulted in unavailability of replacement heifers in Kuwait. Dairy producers resorted to import pregnant heifers for herd replacement. This study was undertaken to investigate the effects of dam vaccination and age, serum Immunoglobulin (Ig) on disease syndromes and mortality in pre-weaned calves. Approach: Late pregnant Holstein Friesian … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,555 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring the Reuse Potential of Chemical Sludge from Textile Wastewater Treatment Plants in India-A Hazardous WasteHema Patel, Suneel PandeyProblem statement: This study was conducted to explore the reuse potential of the chemical sludge (considered as hazardous waste as per Indian Government Hazardous Waste Management Rules) generated from combined effluent treatment in textile clusters. These textile clusters mainly cover the cotton dyeing and printing operations. Approach: Therefore, treatability studies of chemical sludge were conducted using solidification/stabilization treatment to examine … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractBase Course Modification through Stabilization using Cement and BitumenS. M. Marandi, P. SafapourThe main objectives of this research was to analyze the use of combined cement and bitumen emulsion in base course stabilization in details and examine its replacement with conventional pavement in regions with low quality materials and limited construction period. To conduct the objectives, the research divided into three phases. Phase I involved the optimization of cement and bitumen emulsion. … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractPowerful Features of the Modern Syllogistic Method of Propositional LogicAli Muhammad Rushdi, Omar Mohammed Ba-RukabIn traditional propositional logic, many replacement and inference rules were involved to ascertain if the truth of several antecedents implied the truth of a particular consequent. This research described a powerful technique called the Modern Syllogistic Method (MSM), which ferreted out from a set of premises all that can be concluded from it and casted the resulting conclusions in the … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 7,108 accessesView PDFCite

Research ArticleOpen accessIn the abstractFault Node Detection and Connectivity Restoration with Mobile Relay Node in Wireless Sensor NetworksM.P. Anuradha, A.M. Swetha, Manivannan DoraipandianIn Wireless Sensor Network (WSN), node failure is an imperative concern in a hostile environment. These node failures create disjoints in the network and leads to a network partitioning problem. It is important for the nodes to be alive and communicate with each other to check the network connectivity. Replacement of Mobile Relay Nodes (MRN) in the location of faulty … …Journal of Computer Science, Vol. 16, Issue 4 · 1 Apr 2020 · 7,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractWettability and Interfacial Tension Alteration of Rare-Earth Doped Yttrium Iron Garnet under Influence of Electromagnetic WavesLau Zhen Yin, Lee Kean Chuan, Beh Hoe Guan et al.Yttrium Iron Garnet (YIG) doped with rare-earth elements have shown to alter the magnetic properties of garnet nanoparticles (NPs), which is believed to have direct influence on the wettability, interfacial tension and viscosity alteration of garnet nanofluids. In this study, Y2.8R0.2Fe5O12 (R = Lanthanum (La), Neodymium (Nd) and Samarium (Sm)) NPs were synthesized by using the sol gel auto-combustion method … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 25 Jul 2019 · 7,684 accessesView PDFCite
