An experience with different teaching methodologies at mechanical engineering program

This article present a college course experience taught in second year of Mechanical Engineering program, ‘Strength of Materials’ a course of 6 ECTS points. With the aim to improve the learning process, to develop competences and skills and to create opportunities for interaction between students and between student and lecturers, several active learning strategies have been set up in the course. Several actions have been introduced in our lectures, making use of different teaching methodologies: master class, active learning (AL) and problem based learning (PBL). The actions introduced in the practical lectures are focused in program specific and professional competences related to the academic discipline, but also want to train core and cross-cultural competences such as management of information, team work and development of technical reports. At the end of the course a questionnaire was passed to the students in order to analyse which of these activities is the one they believe has the greatest influence in the learning process.Postprint (author's final draft

A calculation/simulation system of sails communicated in real time with wireless sensors

The model presented in this paper is part of the development and integration of a System to Support Decision (SAD) for assistance in the design and actuation of sails. The model is based on the union of a wireless sensor system, continuously connected to a calculation/simulation system. This system will predict the structural behavior and performance of the different configurations of the rigging of a sailing ship. The simulation software will be communicated in real time with wireless sensors and interfaces through suitable filters. The information gathered by the sensors, which are integrated into the structure of the boat, will be used in numerical algorithms to determine the efforts that are suffering the Structure and evaluate the overall performance of the sailboat. The system of calculation / simulation is made up of a model of structural calculation based on a quasi-static method with a formulation for large displacement typical of the finite element method, and includes models of membranes, cables and bars. And the starting point of the simulation tool of fluid dynamics is the method of vortices (contour elements). The algorithms are adapted so that they can make real-time data that offers the monitoring system. The software also has algorithms simulation maneuver with which you can change the position of the sails.Postprint (published version

Adapting the existing coastal patí a vela fleet for scientic purposes

This paper presents the first results of the Barcelona Institute of Culture’s grant for research and innovation projects under the 2019 Barcelona Science Plan entitled “Development of a citizen monitoring program for the Barcelona waters: The Scientific Pat´i a Vela”. The main objective of this project is to develop a small Pat´i a Vela (PV) fleet that can routinely sample the Barcelona coastal waters and report their observations to an open-access interactive web. The Pat´i a Vela boat was designed in 1942 by the Mong´e brothers. It is a lightweight one- person catamaran with a single Marconi sail and no boom. The main objective of this contribution is to adapt the Pat´i a Vela model attaching an on-board platform with scientific instruments (sensors and devices) and determine the new stability characteristics and seakeeping performance. This will allow an adequate sampling of the Barcelona coast waters and the systematic measurements of the essential physical and biogeochemical variables detecting variations along the coast, hence identifying potential sources of contamination. It will also provide the necessary knowledge of natural and anthropogenic seasonality.Postprint (published version

Development of a citizen monitoring program for the Barcelona coastal waters: The Scientific Patí Vela (Patí Científic)

Special issue 9th MARTECH: International Workshop on Marine Technology: 16-18 June 2021, Vigo, Spain.-- 2 pages, 2 figuresThe first results of the PATI CIENTIFIC project are presented. This is a collaborative project funded by a Barcelona Institute of Culture’s grant for research and innovation under the 2019 Barcelona Science Plan. The main objective of this project is to develop a monitoring program for the coastal waters of Barcelona through a small-sailboat feet of the traditional and sustainable Patí de Vela (sailing skate). This pleasure boat is to become a scientifc sailing skate. This feet will acquire the essential oceanographic variables along the Catalan coast, which will be incorporated and accessible in a web platform. We present the initial adaptations done to the Patí de Vela to have an onboard platform holding the scientifc instruments (sensors and devices) for sampling the Barcelona coastal waters. These adaptations allow the systematic measurements of the essential physical and biogeochemical variables. These data, which will allow detecting variations along the coast, hence identifying potential sources of contamination and also providing the necessary knowledge of natural and anthropogenic seasonality, and will be freely available on a web platform. The PATI CIENTIFIC project will increase our knowledge of the coastal waters of the Barcelona coast, encouraging participation in sea monitoring activities and increasing social awareness on the need to love and protect our oceansThe work of Raul Bardaji is supported by the CSIC Intramural Project EMSO – Laboratorios Submarinos Profundos.

Barcelona Coastal Monitoring with the “Patí a Vela”, a Traditional Sailboat Turned into an Oceanographic Platform

Special issue Technological Oceanography.-- 16 pages, 12 figures, 3 tables.-- Data supporting reported results can be found at https://paticientific.org/index.php/dades/ (accessed on 13 April 2022) and through https://zenodo.org/search (accessed on 13 April 2022) by searching “pati cientific”.Shelf waters near large cities, such as Barcelona, are affected not only by meteorological episodes but also by anthropogenic influence. Scientists usually use data from on-site coastal platforms to analyze and understand these complex water ecosystems because remote sensing satellites have low spatiotemporal resolution and do not provide reliable data so close to the coast. However, platforms with conventional oceanographic instrumentation are expensive to install and maintain. This study presents the scientific adaptation and initial measurements from a “patí a vela”, which is a very popular unipersonal catamaran in Barcelona. This versatile sailing vessel has been adapted to contain several low-cost sensors and instruments to measure water properties. Here, we describe the setup of a multi-parameter prototype, and then focus on results obtained using a low-cost temperature profiler. First, the temperature data are compared and validated with another conventional oceanographic instrument used in monthly oceanographic cruises. Then, field measurements between July and November 2021 are used to explore the relationship between air and water temperature in the Barcelona coastal area, showing the seasonal evolution of the temperature profile. We conclude that citizen sampling from fully sustainable sailing boats may turn into an effective strategy to monitor the urban coastal watersThis work has been carried out within the framework of the 2019 Barcelona Pla de Ciència, with funding from the Barcelona City Council through the project “Development of a citizen monitoring program for the Barcelona coastal waters: the Scientific Patí Vela” (PATI CIENTIFIC; references 19SO1645-006, 19SO1649-006, 19SO1651-006).
