Sparse regression interaction models for spatial prediction of soil properties in 3D
(Elsevier Ltd, 2018)
An approach for using lasso (Least Absolute Shrinkage and Selection Operator) regression in creating sparse 3D models of soil properties for spatial prediction at multiple depths is presented. Modeling soil properties in ...
Alkali-activated concrete with Serbian fly ash and its radiological impact
(Elsevier Ltd, 2017)
The present paper reports the results of a study on different types of fly ash from Serbian coal burning power plants and their potential use as a binder in alkali-activated concrete (AAC) depending on their radiological ...
Application of fuzzy AHP for ranking and selection of alternatives in construction project management
(Taylor and Francis Ltd., 2017)
The construction project management (CPM) is very important and large segment of entire project management (PM). Realisation of construction projects is usually long term process which requests significant financial, ...
Calibration of a 1D/1D urban flood model using 1D/2D model results in the absence of field data
(Water Science and Technology, 2011)
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface ...
Cyclic plasticity of trusses
(Springer Verlag, 2015)
In this paper, the Preisach model of hysteresis, which was already successfully implemented for solving problems of cyclic plasticity of axially loaded bar and cyclic bending of elastoplastic beam, is extended to the ...
Derivation of the Husimi symbols without antinormal ordering, scale transformation and uncertainty relations
(Institute of Physics Publishing, 2015)
We propose a new method for the derivation of Husimi symbols, for operators that are given in the form of products of an arbitrary number of coordinates, and momentum operators, in an arbitrary order. For such an operator, ...
Machine Learning Techniques for Modelling Short Term Land-Use Change
(MDPI AG, 2017)
The representation of land use change (LUC) is often achieved by using data-driven methods that include machine learning (ML) techniques. The main objectives of this research study are to implement three ML techniques, ...
Estimating the Performance of Random Forest versus Multiple Regression for Predicting Prices of the Apartments
(MDPI AG, 2018)
The goal of this study is to analyse the predictive performance of the random forest machine learning technique in comparison to commonly used hedonic models based on multiple regression for the prediction of apartment ...
Verification of deflection according to Eurocode 2
(Wiley-Blackwell, 2017)
Code provisions for a simplified check of the long-term deflection of concrete structures are generally developed for predefined values of the relevant input parameters. Deflection calculation may be of interest to account ...
Matrix Stiffness Method for Composite and Prestressed Beam Analysis Using Linear Integral Operators
(Springer Verlag, 2015)
In the paper, the analysis of composite and prestressed beams using the matrix stiffness method is presented. The stiffness matrix for the frame element with a moment release at one end and the vector of equivalent nodal ...
