Research ArticleOpen accessIn the abstractEffects of Adhesive on Coupling Efficiency of Planar Light Waveguide PackagingYang Bo, Duan Ji-anProblem statement: Advanced optoelectronic devices are a kind of key and basic components for next generation communication, untouched sensor, medical testing. They have lots of advantages including greater communication performance, larger capacity, and more fixable form. But light coupling and package structure seriously affects performance of optoelectronic devices. So a lot of attaching methods were proposed to package optoelectronic devices. … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 7,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractBayesian Regularization in a Neural Network Model to Estimate Lines of Code Using Function PointsK. K. Aggarwal, Yogesh Singh, Pravin Chandra, Manimala PuriIt is a well known fact that at the beginning of any project, the software industry needs to know, how much will it cost to develop and what would be the time required ? . This paper examines the potential of using a neural network model for estimating the lines of code, once the functional requirements are known. Using the … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 30,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Rotation Effect on Shear Horizontal Surface Wave in a Piezoelectric Semi-Space Covered by a Semiconductor FilmFatimah AlshaikhIn this study, a mathematical model of the rotation effect on Shear Horizontally wave (SH-wave) propagation in a piezoelectric semi-space covered by a semiconductor film is investigated. The semiconducting layer is rotating with a constant angular velocity and the interface between the piezoelectric substrate and the semiconductor layer is imperfectly bonded. Furthermore, the surfaces of the bilayer system assumed free … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 29 Apr 2017 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime Dimension Parameters of the Dual-Porosity Reservoir Determination using Periodic Hydraulic Pulse TestingMarat Ovchinnikov, Kushtanova Galiya GatinishnaThe process of periodic hydraulic pulses propagation in porous fractured media of dual-porosity near a vertical well is considered. Using the calculation data as the base, it is shown that the effect of the time dimension constant on the form of the filtration wave curves is essential. The conclusions on possibility of hydrodynamic model types verification which adequately describe the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 9 Sep 2016 · 6,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Efficiency Analysis of a TR-UWB SystemAdil El Abboubi, Fouzia Elbahhar, Marc Heddebaut et al.In wireless communications, where sensors operate on batteries, the energy consumption must be reduced while considering the communication range and data rate requirements. In this context we analyze and compare, in this study, the UWB and TR-UWB system in terms of the total energy consumption. So, for that, we develop an analytical model to estimate the energy consumption of a … …Journal of Computer Science, Vol. 12, Issue 1 · 15 Feb 2016 · 7,321 accessesView PDFCite
HypothesisOpen accessIn the abstractReal-Time Automatic Inspection System for the Classification of PCB Flux DefectsAng Teoh Ong, Aouache Mustapha, Zulkifilie Bin Ibrahim et al.Automatic inspection based on a real-time machine vision system may serve as substitute for the manual human visual inspection of flux defects in Printed Circuit Boards (PCBs), which often cause damage on the board in the form of corrosions that harm the assembly. The concept of automatic inspection contributes to the improvement of the manufacturing quality of PCBs and facilitates … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 25 Aug 2015 · 8,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractMIGITATION OF INTER CELL INTERFERENCE AND FADING IN LTE SYSTEMSNagarajan Amutha Prabha, Gorla Vidhya Sagar, Venugopal ManikandanIn this study we investigate the compensation of outage area utmost. It introduces the self optimization of the neighbors of the outage cells with antenna tilts for the generation of the most suitable configuration settings for the network with base stations/eNodeBs positional information. All the neighbors of the outage cell increase their coverage area and thus contribute to cell outage … …Journal of Computer Science, Vol. 10, Issue 3 · 28 Nov 2013 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Ensemble Prediction Algorithms for Detecting Faulty Modules in Object Oriented Systems Using Quality MetricsM. Punithavalli, C. NeelamegamThe high usage of software system poses high quality demand from users, which results in increased software complexity. To address these complexities, software quality engineering methods should be updated accordingly and enhance their quality assuring methods. Fault prediction, a sub-task of SQE, is designed to solve this issue and provide a strategy to identify faulty parts of a program, so … …Journal of Computer Science, Vol. 8, Issue 12 · 20 Dec 2012 · 6,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Improved Directed Diffusion Protocol for Sensor Networks under Different Mobility ModelsK. E. Kannammal, T. PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractPore Water Pressure Contribution to Debris Flow MobilityChiara DeangeliProblem statement: Debris flows are very to extremely rapid flows of saturated granular soils. Two main types of debris flow are generally recognized: Open slope debris flows and channelized debris flows. The former is the results of some form of slope failures, the latter can develop along preexisting stream courses by the mobilization of previously deposited debris blanket. The problem … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,591 accessesView PDFCite
