Study of early P91 dual corrosion in steam and simulated combustion gases from a gas-fired boile
(2021-07-25)
P91 ferritic steel pipes face dual environments during boilers operation: steam-side and fire-side. This P91 steel assessment differs from the dual studies performed to simulate coal-fired boilers -oxyfuel/steam atmospheres- ...
A hybrid approach based on socp and the discrete version of the sca for optimal placement and sizing dgs in ac distribution networks
(2020-12-27)
This paper deals with the problem of the optimal placement and sizing of distributed generators (DGs) in alternating current (AC) distribution networks by proposing a hybrid master–slave optimization procedure. In the ...

Application of the vortex search algorithm to the phase-balancing problem in distribution systems
(2021-02-26)
This article discusses the problem of minimizing power loss in unbalanced distribution systems through phase-balancing. This problem is represented by a mixed-integer nonlinear-programming mathematical model, which is ...
Reduction of losses and operating costs in distribution networks using a genetic algorithm and mathematical optimization
(2021-02-09)
This study deals with the minimization of the operational and investment cost in the distribution and operation of the power flow considering the installation of fixed-step capacitor banks. This issue is represented by a ...
Girls Do Not Sweat: the Development of Gender Stereotypes in Physical Education in Primary School
(2020-06-27)
Despite efforts towards gender equality, from an early age, girls practice sport less than boys. Explaining this is paramount to psychology. Stereotypes about gender-appropriate behaviour play a key role in doing physical-sports ...
Classical simple Lie 2-algebras of odd toral rank and a contragredient Lie 2-algebra of toral rank 4
(2021-04-29)
After the classification of simple Lie algebras over a field of characteristic p > 3, the main problem not yet solved in the theory of finite dimensional Lie algebras is the classification of simple Lie algebras over a ...
On some families of subsemigroups of a numerical semigroup
(2020-04-07)
To a given numerical semigroup S we associate a family of subsemigroups {휕nS}, n ∈ ℕ, that permits us to understand some of the structure of S. We characterize this family in case S is a supersymmetric numerical semigroup ...
