Integrating perceptions of safety and bicycle theft risk in the analysis of cycling infrastructure preferences
(2021-06-30)
Cycling infrastructure development is an effective but expensive urban policy to encourage people to use bicycles. Although people usually prefer infrastructure with high cycling priority, authorities in some cities have ...
Application of the Multiverse Optimization Method to Solve the Optimal Power Flow Problem in Direct Current Electrical Networks
(2021-08-04)
This paper addresses the optimal power flow problem in direct current (DC) networks employing a master–slave solution methodology that combines an optimization algorithm based on the multiverse theory (master stage) and ...
Optimal Location and Sizing of DGs in DC Networks Using a Hybrid Methodology Based on the PPBIL Algorithm and the VSA
(2021-08-11)
In this paper, we propose a master–slave methodology to address the problem of optimal integration (location and sizing) of Distributed Generators (DGs) in Direct Current (DC) networks. This proposed methodology employs a ...
A sustainability maturity model for micro, small and medium-sized enterprises (MSMEs) based on a data analytics evaluation approach
(2021-05-28)
A maturity model for micro, small and medium enterprises (MSMEs) is introduced to assess the level of
implementation of sustainability strategies and practices in this type of business. According to the literature, only
a ...

Optimal integration of photovoltaic sources in distribution networks for daily energy losses minimization using the vortex search algorithm
(2021-04-20)
This paper deals with the optimal siting and sizing problem of photovoltaic (PV) generators in electrical distribution networks considering daily load and generation profiles. It proposes the discrete-continuous version ...
Mean Dimension and Metric Mean Dimension for Non-autonomous Dynamical Systems
(2020-10-07)
In this paper we extend the definitions of mean dimension and metric mean dimension for non-autonomous dynamical systems. We show some properties of this extension and furthermore some applications to the mean dimension ...
The equivalence between successive approximations and matricial load flow formulations
(2021-03-24)
This paper shows the equivalence of the matricial form of the classical backward/forward load flow formulation for distribution networks with the recently developed successive approximations (SA) load flow approach. Both ...
