Research ArticleOpen accessEvery word in the titleWeather Forecasting Using Merged Long Short-Term Memory Model (LSTM) and Autoregressive Integrated Moving Average (ARIMA) ModelAfan Galih Salman, Yaya Heryadi, Edi Abdurahman, Wayan SupartaWeather forecasting is an interesting research problem in flight navigation area. One of the important weather data in aviation is visibility. Visibility is an important factor in all phases of flight, especially when the aircraft is maneuvering on or close to the ground, i.e., during taxi-out, take-off and initial climb, approach and landing and taxi-in. The aim of these study … …Journal of Computer Science, Vol. 14, Issue 7 · 28 Jun 2018 · 11,437 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntibody Responses to HIV-1 gp120 Hypervariable Regions in Six Long-Term Non-ProgressorsRebecca Rivera, Kyung Hee Kang, Murray B. Gardner et al.Our long-term goal is to discover the combination of host parameters that help some HIV-infected individuals to resist progression to AIDS. In this study, we examined antibody responses using multiple samples obtained from a cohort of Long-Term Non-Progressors (LTNPs). Our hypothesis is that antibody responses to variable regions of the HIV-1 envelope glycoprotein are involved in reducing the viral load … …American Journal of Infectious Diseases, Vol. 12, Issue 2 · 1 Jul 2016 · 7,658 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleField Data Based Method for Predicting Long-Term SettlementsJianping Jiang, Qingsheng Chen, Sanjay NimbalkarThe estimation of the long-term foundation settlement in soft soil is very complex, which is attributed to a number of uncertainties associated with various factors, such as: (i) The compressibility parameters obtained in the laboratory from samples of relatively small size that are more homogeneous compared to heterogeneous field sediments in which various soil types may be interlayered at random … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 22 Feb 2016 · 8,255 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransient Stability of the Power System with the Exact Long Transmission Line ModelPrechanon KumkratugProblem statement: The exact long transmission line model consists of the lump of the series resistance, reactance and shunt capacitance. With the consideration the actual long transmission line model, it causes in the difficulty of deriving the mathematical model. Approach: This study investigates the transient stability of power system with consideration the exact long transmission line model. The concept of … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 24 Jan 2012 · 6,856 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of Vegetation Dynamics using Long-Term Normalized Difference Vegetation Index Time-SeriesTamara Bellone, Piero Boccardo, Francesca PerezProblem statement: The Normalized Difference Vegetation Index (NDVI) is the most extensively used satellite-derived index of vegetation health and density. Since climate is one of the most important factors affecting vegetation condition, satellite-derived vegetation indexes have been often used to evaluate climatic and environmental changes at regional and global scale. The proposed study attempted to investigate the temporal vegetation dynamics … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,406 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGamma Radiosensitivity Study on Long Bean (Vigna sesquipedalis)Ellyfa Kon, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidThis study was conducted to determine the LD50 and effect of gamma ray on germination percentage, plant height, survival percentage, root length, root dry weight and shoot dry weight of seedlings derived from seeds of long bean (Vigna sesquipedalis). Seeds of this crop were treated with 300, 400, 500, 600 and 800 Gy gamma rays at Malaysian Institute of Nuclear … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,601 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStrong Dependence at the Long Run and the Cyclical Frequencies in the Specification of the US Unemployment RateL. A. Gil-AlanaThis study deals with the presence of long range dependence at the long run and the cyclical frequencies in the specification of the US unemployment rate. We use a parametric procedure that permits us to test unit and fractional roots in raw time series. The results show that both the long run and the cyclical structures present a component of … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,506 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLONG-REACH OPTICAL ACCESS NETWORKS (LR-OANS): A PROMISING CANDIDATE FOR FUTURE OPTICAL ACCESSI.M.M. Mohamed, M.S. Ab-RahmanThe ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, creates the motivation to upgrade the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs). Beside the need for more bandwidth per user, a further extension in the range and an increase in the split … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Aug 2014 · 6,708 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtility Based Scheduling and Call Admission Control for Long Term Evolution NetworksJ. Vijay Franklin, K. ParamasivamIn this study, we propose to design a call admission control algorithm which schedules the channels for Real time and non-real time users. In Long Term Evolution (LTE) 3GPP Networks, several works were done on call admission control but these works rarely considers scheduling of resources to the real time and non-real time users.When the system meets traffic oriented performance … …Journal of Computer Science, Vol. 8, Issue 12 · 13 Dec 2012 · 6,791 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLength Measurement of Long Gauge Blocks by InterferometerKanokporn Kohmun, Pichet Limsuwan, Monludee Ranusawud, Prathan BuranasiriA gauge block interferometer with a vacuum chamber was designed and constructed for the measurement of gauge block lengths between 10 to 1,000 mm. In the chamber, four gauge blocks under the length measurement can be mounted on the measuring table. Furthermore, the length of all four gauge blocks can be measured continuously in one measurement. In this study, four … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 26 Sep 2020 · 7,102 accessesView PDFCite
