Research ArticleOpen accessEvery word in the titleModeling of Multi-Level Capacitated Lot-Size Scheduling ProblemZuhaimy Ismail, Diyana Abd Mahad, Tan Siew ChingProblem statement: Lot-size is the clustering of items for transportation or manufacturing processes occurring at the same time. The issue in lot-size problem is to design production processes so that the feasible production quantities are equal to customer demand quantities and the timing of production is such that inventory positions are almost zero. Approach: In this study, we explore the … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,319 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleControlling Label Size Increment of Efficient XML Encoding and Labeling Scheme in Dynamic XML UpdateMeghdad Mirabi, Hamidah Ibrahim, Ali Mamat et al.Problem statement: In order to facilitate XML query processing, labeling schemes are used to determine the structural relationships between XML nodes. However, labeling schemes have to reliable the existing nodes or recalculate the label values when a new node is inserted into the XML document during XML update process. EXEL as a labeling scheme is able to remove relabeling for … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,417 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComputation of Hahn Moments for Large Size ImagesA. Venkataramana, P. Ananth RajProblem statement: Direct formulas used for Hahn moments computation available in the literature are not applicable for large size images. This is due to the need for calculation of factorial of large values as well as numerical instability in the calculation of polynomial values. This study presents a method to correct these errors. Approach: In this research, recursive formulas for … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,092 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRepresentative Particle Size of Sediment in Storm Sewer InletsJaber Almedeij, Ebtehal Ahmad, Jasem AlhumoudProblem statement: The aim of this study was examine the representative particle size of noncohesive sediment samples collected from different storm sewer inlets in residential catchments within Kuwait. Approach: A number of 25 sediment samples were collected from storm sewer inlets located in five residential areas in Kuwait: Bayan, Al-Nuzha, Al-Feiha, Al-Andalos and Al-Rumaithya. All the impervious areas for the … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,934 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Grain Size on Selected Physico-Chemical Properties of ClayOsumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Mixture of the right proportion of expanding and non-expanding clays to improve plasticity (moldability) of clays used in the pot industry of Malaysia is yet to be well investigated. In addition, little is known about the choice of the right clay size to eliminate or reduce the content of undesirable compounds such as Fe2O3, Al2O3 to improve the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,998 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproving the Accuracy of Effort Estimation through Fuzzy Set Representation of SizeCh. Satyananda Reddy, KVSVN RajuProblem statement: The precision and reliability of the effort estimation is very important for the competitiveness of software companies. The uncertainty at the input level of the Constructive Cost Model (COCOMO) yields uncertainty at the output, which leads to gross estimation error in the effort estimation. Fuzzy logic-based cost estimation models are more appropriate when vague and imprecise information was … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,085 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimal Decentralized Spectral Resource Allocation for Orthogonal Frequency Division Multiple Access Downlink of Femto Networks Via Adaptive Gradient Vector Step Size ApproachLamia Benmesbah, Bingo Wing-Kuen Ling, Vikram Chandrasekhar et al.Problem statement: For the Orthogonal Frequency Division Multiple Access (OFDMA) downlink of a femto network, the resource allocation scheme would aim to maximize the Area Spectral Efficiency (ASE) subject to constraints on the radio resources per transmission interval accessible by each femtocell. Approach: An optimal resource allocation scheme for completely decentralized femtocell deployments leads to a nonlinear optimization problem because … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 14 Jan 2012 · 7,637 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFish Recognition Based on Robust Features Extraction from Size and Shape Measurements Using Neural NetworkMutasem Khalil Alsmadi, Khairuddin Bin Omar, Shahrul Azman Noah, Ibrahim AlmarashdehProblem statement: Image recognition is a challenging problem researchers had been research into this area for so long especially in the recent years, due to distortion, noise, segmentation errors, overlap and occlusion of objects in digital images.
