Localization is a crucial skill in mobile robotics because the robot needs to make reasonable navigation decisions to complete its mission. Many approaches exist to implement localization, but artificial intelligence can be an interesting alternative to traditional localization techniques based on model …

The transmission of constant-envelope orthogonal frequency division multiplexing (CE-OFDM) signals, based on electrical phase modulation, was shown to improve the tolerance to noise and the nonlinearity introduced by light-emitting diodes (LEDs) in visible light communication (VLC) systems. This allows …

The performance of a visible light communication (VLC) system based on power domain non-orthogonal multiple access (PD-NOMA) is experimentally evaluated in this paper. The simplicity of the adopted non-orthogonal scheme is provided by the fixed power allocation method at the transmitter and the single …

Laboratory experiments are important pedagogical tools in engineering courses. Restrictions related to the COVID-19 pandemic made it very difficult or impossible for laboratory classes to take place, resulting on a fast transition to simulation as an approach to guarantee the effectiveness of teaching. …

Purpose. Psychological contracts (PC) capture employees’ mental schema of the exchange agreement between themselves and their organizations, through which they make sense of their daily work environment (Rousseau, 2001). PCs are not only influenced by (large) organizational changes (Freese et al., 2011), …

The illicit drug trafficking is a problem since many years which seems not to get solved. The main question …

Tropical deforestation is one of the main causes for habitat destruction and fragmentation for bird communities worldwide, but Costa Rica is one of the few countries where forest cover increased. Biodiversity in Costa Rica is astonishing, especially in the isolated cloud forests of the ecoregion ‘Talamancan …
