Research ArticleOpen accessEvery word in the titleEnhancing the Urea-N Use Efficiency in Maize (Zea mays) Cultivation on Acid Soils using Urea Amended with Zeolite and TSPOsumanu Haruna Ahmed, Aminuddin Hussin, Husni Mohd Hanif Ahmad et al.Problem Statement: Ammonia loss significantly reduces urea-N use efficiency in crop production. Efforts to reduce ammonia loss are laboratory oriented, as such limited in reflecting actual field conditions. This paper reports the effects of urea amended with triple superphosphate (TSP) and zeolite (Clinoptilolite) on soil pH, soil nitrate, soil exchangeable ammonium, dry matter production, N uptake, fresh cob production and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,874 accessesView PDFCite
Research ArticleOpen accessIn the keywordsParticulate Matter in the Excavation Work Sites in Urban AreasGiuseppe Pizzo, Marina ClericoProblem statement: Excavation work sites in urban areas for infrastructures and buildings cause a great deal of disturbance and damage due to the emission of particulate matter, in particular in the area involved in urban renovation work. Under Italian legislation limits currently exist for PM10 and PM2, 5 but, in the case of excavation work sites, it would be also … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 23 Dec 2011 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved Genetic Algorithm for the Traveling Salesman Problem with Multi-RelationsSupat PatvichaichodProblem statement: The aim of this research is to investigate the Traveling Salesman Problems with Multi-Relations (TSPMR) in which each of the vertices has several edges and different weights. The study concerns the weights fluctuated by time in which the problem has more complexity than general TSP problem. However, this type of problem closes to the real-world situation in engineering … …Journal of Computer Science, Vol. 7, Issue 1 · 14 Jan 2011 · 6,924 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEmbedding Malaysian House Red Ant Behavior into an Ant Colony SystemZ. A. Othman, H. M. Rais, A. R. HamdanProblem statement: Ant Colony System (ACS) is the most popular algorithm used to find a shortest path solution in Traveling Salesman Problem (TSP). Several ACS versions have been proposed which aim to achieve an optimum solution by adjusting pheromone levels. However, it still has a room on an improvement. This research aims to improve the algorithm by embedding individual Malaysian … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,961 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Traveling Salesman Problem as a Benchmark Test for a Social-Based Genetic AlgorithmN. A. AL-Madi, A. T. KhaderPresent research, showed Traveling Salesman Problem (TSP) to compare values and results concerning the averages and best fits of both, Simple Standard Genetic Algorithm (SGA) and a new approach of Genetic Algorithms named Social-Based Genetic Algorithm (SBGA). Results from TSP test on Social-Based Genetic Algorithms (SBGA) were presented. Results were encouraging in Social-Based Genetic Algorithms (SBGA) performs better in finding … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,843 accessesView PDFCite
Research ArticleOpen accessIn the keywordsED-XRF Analysis of Total Suspended Particulates from Enamelware Manufacturing IndustryJ. A. Sonibare, F. A. Akeredolu, O. Osibanjo, I. LatinwoConcentration and elemental composition of the total suspended particulates (TSP) emitted due to manufacturing activities of an enamelware industry in Lagos, Nigeria were investigated. Gravimetric method was used in mass concentration determination and an energy dispersive x-ray fluorescence (ED-XRF) analyzer was employed in the multi-elemental analysis. The Federal Ministry of Environment (FMENV, Nigeria's environment regulating body) set limit of 250 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,683 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of Hybrid Encoding Genetic Algorithm on Pickup and Delivery Traveling Salesman Problem with Traffic ConditionsSupat PatvichaichodProblem statement: This study deals with the pickup and delivery traveling salesman problem with traffic conditions (PDTSPTW), an extension of the pickup and delivery traveling salesman problem (PDTSP) where each customer to be served is associated with two quantities of product to be collected and delivered. Almost PDTSP problems uses distance between each point of customers as Euclidean Distance and … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,779 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Capacitated Vehicle Routing Problem by Nested Particle Swarm OptimizationKaruppusamy Kanthavel, Paruchuri PrasadProblem statement: Vehicle routing problem determines the optimum route for each vehicle as a sequence of visiting cities. The problem has been defined as NP-hard and exact solution is relatively difficult to achieve for real time large scale models. Though several attempts to solve the problem were made in the literature, new approaches may be tried to solve the problem … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomics of Boro Rice Production in Rangpur District of Bangladesh: Comparative Assessment of Urea Super Granule and Traditional Urea ApplicationMd. Farhad Masum, Md. Monirul Islam, Arifa Jannat, Aurup Ratan DharThe study was examined the profitability of Boro rice production using Urea Super Granule (USG) and traditional urea in Rangpur district of Bangladesh. 60 farmers were selected randomly for the present study. The cultivation of Boro rice was profitable from the viewpoint of the farmers. Per hectare net return for USG user and traditional urea user was Tk. 40264.4 and … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 14 Apr 2018 · 8,684 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Gaussian Process Regression Model for the Traveling Salesman ProblemWanatchapong Kongkaew, Juta PichitlamkenProblem statement: Traveling Salesman Problem (TSP) is a famous NP hard problem. Many approaches have been proposed up to date for solving TSP. We consider a TSP tour as a dependent variable and its corresponding distance as an independent variable. If a predictive function can be formulated from arbitrary sample tours, the optimal tour may be predicted from this function. … …Journal of Computer Science, Vol. 8, Issue 10 · 30 Aug 2012 · 7,367 accessesView PDFCite
