Synthesis of novel multi-functionalized pyrrolidines by [3 + 2] dipolar cycloaddition of azomethine ylides and vinyl ketones
(Monatshefte fuer Chemie/Chemical Monthly, 2019-02)
An efficient and easy synthetic route to substituted pyrrolidine derivatives has been established through [3 + 2] dipolar cycloaddition of vinyl ketones and azomethine ylides. The reactions proceed smoothly, under mild ...
Novel 4-ferrocenyl-8-(phenylthio)-1,2,3,4-tetrahydroquinoline: Design, synthesis and spectral characterization
(The University Thought - Publication in Natural Sciences, 2019)
Herein, we report design, synthesis and spectral characterization of novel 4-ferrocenyl-8-(phenylthio)-1,2,3,4-tetrahydroquinoline. Desired synthesis was achieved in three reaction steps, with a good overall yield (67%). ...
The Non-Linear Regression - the Levenberg- Marquardt Algorithm for Assumption the Energy Losses of Hydraulic Transport in a Case of the Mine Trepca
(Thermal Science, 2019)
The main problem of hydraulic transport is the resistance generated during the mixture transport through the pipe-line. Testing the flow characteristics of mixtures, shown in this paper, are based on the principles of ...
The proof of the Perepechko’s conjecture concerning near-perfect matchings on Cm x Pn cylinders of odd order
(Applicable Analysis and Discrete Mathematics, 2019-01)
For all odd values of m, we prove that the sequence of the numbers of near-perfect matchings on Cm x P2n+1 cylinder with a vacancy on the boundary obeys the same recurrence relation as the sequence of the numbers of perfect ...
Assessment of electronic system for e-patent application and economic growth prediction
(Physica A: Statistical Mechanics and its Applications, 2019-04)
Information system development is a complex endeavor, one which is fraught with peril if one do not follow a proven method. The Rational Unified Process (RUP) is one such method which could help to organize the development ...
Multivariate and multi-scale generator based on non-parametric stochastic algorithms
(Journal of Hydroinformatics, 2019)
A method for generating combined multivariate time series at multiple locations and at different time scales is presented. The procedure is based on three steps: first, the Monte Carlo method generation of data with ...
Experimental analysis of wavelet decomposition on edge detection
(PROCEEDINGS OF THE ESTONIAN ACADEMY OF SCIENCES, 2019)
The influence of different wavelet transformations and decomposition on edge detection was examined, using convenient operators to images of various complexities. Berkeley Segmentation Database images with the corresponding ...
E-learning engineers based on constructive and multidisciplinary approach
(Computer Applications in Engineering Education, 2019-09)
In this study, we applied constructive approach to education supplemented with the innovation cycle approach. The main goal is to develop the innovative ideas from a clear start up to the implementation phase. Since multiple ...
Hail suppression activities using TETRA-based sensor network
(Sensor Review, 2019)
This paper aims to show the implementation in the terrestrial trunked radio (TETRA)-based sensor network. The publicly available data show that, in Serbia, the annual damage caused by hailstorms in the past seven years has ...
REGRESSION ALGORITHMS IN ASSESSING THE IMPACT OF MORPHOLOGICAL AND MOTOR CHARACTERISTICS ON 60-M SPRINT
(Facta universitatis Series: Physical Education and Sport, 2019)
The aim of the present study was to identify the relationship between morphological parameters and motor skills that are important for sprint performance in children aged 8 to 16 years divided into four age groups (U10, ...
