Assessment of observed and projected climate changes in Bačka (Serbia) using trend analysis and climate modeling
(Hungarian Meteorological Service, 2022-03-08)
Climate change is one of the largest environmental issues causing hydroclimatological extremes such as floods, droughts, and aridity. The aim of this study is to assess the observed and projected climate changes in Bačka ...
An Improved Modification of Accelerated Double Direction and Double Step-Size Optimization Schemes
(MDPI, 2022-01-13)
We propose an improved variant of the accelerated gradient optimization models for solving unconstrained minimization problems. Merging the positive features of either double direction, as well as double step size accelerated ...
Review and validation of photovoltaic solar simulation tools/software based on case study
(De Gruyter, 2022-05-10)
Photovoltaic (PV) systems are an excellent solution to meet energy demand and protect the global environment in many cases. With the increasing utilization of the PV system worldwide, there is an increasing need for ...
Hydrolytic, thermal and radiation stability of modified urea-formaldehyde composites: influence of montmorillonite particle size
(Elsevier, 2022-06-15)
Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF ...
Modeling electrostatic potential in FDSOI MOSFETS: An approach based on homotopy perturbations
(De Gruyter, 2022-01-26)
Modeling of the electrostatic potential for fully depleted (FD) silicon-on-insulator (SOI) metal-oxide-semiconductor field effect transistor (MOSFET) is presented in this article. The modeling is based on the analytical ...
Geodesic infinitesimal deformations of generalized Riemannian space
(Birkhaeuser Verlag AG, 2022-05-11)
Infinitesimal deformations of subspaces of a generalized Riemannian
space are studied in this paper. Variations of some geometric
objects are found. Necessary and sufficient conditions which provide the
existence of a ...
Speaker Recognition Using Constrained Convolutional Neural Networks in Emotional Speech
(Molecular Diversity Preservation International, 2022-03-16)
Speaker recognition is an important classification task, which can be solved using several
approaches. Although building a speaker recognition model on a closed set of speakers under neutral speaking conditions is a ...
Two Interval Upper-Bound Q-Function Approximations with Applications
(Mathematics and computer sciences, 2022-10-10)
The Gaussian Q-function has considerable applications in numerous areas of science and engineering. However, the fact that a closed-form expression for this function does not exist encourages finding approximations or ...
Theoretical investigation of bandwidth of multimode step-index silica photonic crystal fibers
(MDPI, 2022-03-23)
Solving the time-dependent power flow equation (PFE) provides a useful method to study
the transmission bandwidth of step-index silica photonic crystal fibers (SI SPCFs). The transmission
bandwidth of these kinds of ...
Theoretical investigation of the capacity of space division multiplexing with step-index air-clad silica optical fibers
(MDPI, 2022-02-23)
We studied the effect of mode coupling on the space division multiplexing (SDM) capabilities of multimode step-index (SI) air-clad silica optical fibers by numerically solving the power
flow equation. Mode coupling ...
