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 …

In this paper, artificial intelligence tools are implemented in order to predict trajectory positions, as well as channel performance of an optical wireless communications link. Case studies for industrial scenarios are considered to this aim. In a first stage, system parameters are optimized using a …

The nonlinearity induced by light-emitting diodes in visible light communication (VLC) systems presents a challenge to the parametrization of orthogonal frequency division multiplexing (OFDM). The goal of the multi-objective optimization problem presented in this study is to maximize the transmitted …

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. …

The European Open Platform for Prescribing Education (EurOP2 E) seeks to improve and harmonize European clinical pharmacology and therapeutics (CPT) education by facilitating international collaboration and sharing problem-based, online, open educational resources. The COVID-19 pandemic forced teachers …

LETTER TO THE EDITOR: Many doctors take on prescribing responsibilities shortly after they graduate [1, 2], but fnal-year medical students not only feel insecure about prescribing, but also lack adequate knowledge and skills to prescribe rationally and safely [3, 4]. To address this public health concern, …

Research is about consumer behaviour of Poshtel guests in Costa Rica. Interviews, online questionnaire and observation was used to research data. Content Analysis was used to analyse data. Findings are implemented in a Business Plan, being a Poshtel in Costa Rica (Samara Company name) and the solution …

“Biggest cocaine seizure ever in the Port of Antwerp”. (Bervoet, 2020) On the 5th of November 2020, the Belgian newspaper ‘De Tijd’ wrote about a record seizure of cocaine in the port of Antwerp. 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 …
