Research ArticleOpen accessIn the abstractA Resource Conservation Technology for Adapting Argroecosystems to the New Natural Conditions of a Warming Climate in South-Eastern KazakhstanNaziya Suleimenova, Dastan Kalykov, Baglan Makhamedova et al.This article presents the results of research aimed at developing a resource conservation technology for the adaptation of the soybean agroecosystem to the new natural conditions of a warming climate. In particular, measures to combat drought have been studied: The efficiency of soil-protecting technology (Mini-till) and minimization of anthropogenic impact on soil, the effective use of soil moisture and its … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 25 Jun 2021 · 6,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation and Reliability for a Special Type of Semi-Markov ProcessVlad Stefan Barbu, Alex Karagrigoriou, Andreas MakridesThis work deals with multi-state systems modelled by means of semi-Markov processes. The sojourn times are seen to be independent not identically distributed random variables and assumed to belong to one of two different general classes of distributions so that the first class is closed under maxima and the second one is closed under minima. We obtain maximum likelihood estimators … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 20 Oct 2019 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Damage Modelling of Transverse Impact Behavior of Adhesively Bonded Composite JointsDimitrios Athinaios, Konstantinos Tserpes, Giannis FlorosA three-dimensional dynamic numerical model was developed, using the commercially available finite element software LS-DYNA to simulate the Low Velocity Impact (LVI) case on bonded joints consisting of woven CFRP adherents. The adhesive failure simulated using the Cohesive Zone Method (CZM), while the failures in the composite material simulated using a progressive damage material model based on Hashin’s failure criteria. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 3 Apr 2020 · 6,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractLog-Moment Estimators for the Generalized Linnik and Mittag-Leffler Distributions with Applications to Financial ModelingDexter O. Cahoy, Wojbor A. WoyczyńskiWe propose formal estimation procedures for the parameters of the generalized, heavy-tailed three-parameter Linnik gL(α, µ, δ) and Mittag-Leffler gML(α, µ, δ) distributions. The paper also aims to provide guidance about the different inference procedures for the different two-parameter Linnik and Mittag-Leffler distributions in the current literature. The estimators are derived from the moments of the log-transformed random variables and … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 1 Aug 2018 · 7,355 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Hazardous Medical Waste Generation Rates of Private Health Care Facilities-Case Study from Dhaka City of BangladeshMd. Yousuf Rumi, Rezaul KarimMany developing countries are lagging behind the developed countries to properly manage their hazardous healthcare waste. These waste pose a significant epidemiological risks to the general people. To estimate the epidemiological risks and to establish parameters of any waste management plan, quantitative estimation of healthcare waste generation is essential. Most researches on quantitative estimation of healthcare wastes to date, have … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 25 Apr 2018 · 8,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty Analysis of Time of Concentration Equations based on First-Order-Analysis (FOA) MethodAsghar AzizianThe time of concentration (Tc) is one the most important time parameters to predict the response of a catchment to a given rainfall and plays a key role in the hydrologic design and rainfall-runoff modeling. There are a huge number of empirical/semi-empirical equations for estimation of Tc and depending on several parameters such as rainfall attributes, topographic and land cover … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 19 Mar 2018 · 9,294 accessesView PDFCite

The highway structure, as the mine of vibration, includes common layers and also special materials with dumping properties. It is the geomesh reducing the crack creation caused by fatigue, the tension strength increase and excess settlement The stress concentration in the bitumen structure reduces and separates into … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 23 Nov 2017 · 7,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo-Stage Estimation in Inverse Problems using Combined Wavelet Thresholding and Penalized Maximum LikelihoodRobert G Aykroyd, Hassan AljohaniInverse problems occur in a wide range of practical scientific investigations where the variables of interest are only observed indirectly, such as magnetic and seismic imaging in geophysics, electrical tomography in industrial process monitoring, or PET scanning in medicine. Linear inverse problems can be thought of as highly multivariate regression problems with strong multicollinearity where the aim is to interpret … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 29 Sep 2017 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of UE Location Techniques in LTE NetworksYahia Zakaria, Lubomir IvanekThe goal of this research is to evaluate the location accuracy of User Equipment (UE) in Long Term Evolution (LTE) networks which depends on the timing advance parameters. The ability to locate the subscribers through the network is considered as a significant factor in wireless communication systems. The main method to geolocation based on specified distances from many base stations … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 5 Jan 2017 · 8,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Claim Severity Distribution using Variable Neighborhood SearchKunjira Kingphai, Samruam ChongcharoenIn this study, Variable Neighborhood Search (VNS) is utilized to estimate the parameters of actual motor insurance claims data set and compared them obtained by the Moment Estimation Methods (MOM) and Maximum likelihood Estimation Method (MLE) which are known as a conscientious method. Then, the Kolmogorov-Smirnov test (K-S) is used to show how well the selected distribution fits the actual … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 19 Dec 2016 · 7,326 accessesView PDFCite
