• Algal Cultivation for Bioenergy Production: First Mathematical Modelling Results in Raceways

  A. Martínez, L. Alvarez-Vázquez, C. Rodríguez, M. Vázquez-Méndez

  admos2023.

  
  

  Abstract

  The most used algae cultivation systems are the open-channel raceway ponds for their low maintenance and energy costs. Raceways allow algal cultivation using wastewater, where algae mass can be employed as source for bioenergy production. One of the main external factors influencing algal productivity is the velocity of the liquid inside the pond, that can be easily controlled by the position and/or rotational speed of the turning paddle wheel, and by the height of water. In this work we introduce a novel methodology to automate the optimization of the design of raceway ponds based on techniques of optimal control of partial differential equations. So, we formulate the problem as a control problem where the state system is given by the coupled nonlinear equations for hydrodynamics and algae/nitrogen/phosphorus concentrations, and the objective function to be maximized represents the global concentration of algae at final time. We present here a detailed, rigorous mathematical formulation of the optimal control problem, we propose a numerical algorithm for its resolution, and we show some preliminary computational results related to the numerical modelling of the problem.

• Towards a More Efficient Evacuation of Crowds by Means of an Optimal Location of Exit Doors

  L. Alvarez-Vázquez, N. García-Chan, A. Martínez, C. Rodríguez, M. Vázquez-Méndez

  Abstract

  In this work we present a new strategy, employing optimal control techniques of partial differential equations, to automate the optimization of locations for a given number of exit doors at gathering places, so that the evacuation of crowds takes place in a safer and faster way. Once given a detailed mathematical formulation of the problem, in order to solve the constrained optimal control problem numerically, we propose its full discretization, with a space semi-discretization via the finite element method over a family of triangular meshes of the domain under study, and a time semi-discretization via the Euler algorithm. Finally, for the resulting discretized minimization problem, we try its optimization by means of a derivative-free algorithm. Numerical examples, corresponding to different scenarios for a real-world study case posed on “Plaza de la Liberación” (Guadalajara, Mexico), are presented and discussed to assess the effectiveness of our approach.

• D8.3 (WP8): Development of the exploitation plan

  D. Bao

  prodPhD OA (2023). 10

  
  

  Abstract

  This document presents the exploitation strategy jointly designed by the consortium as well as individual exploitation intentions of each partner organisation. It includes the actions to be carried out beyond the project lifetime to ensure that prodPhD outcomes are as widely reused as possible, including improvement of the project results, pre-commercialisation action and future exploitation ideas and intentions.

• D6.3 (WP6): Report on monitoring the project developments

  E. Sanz, P. Alonso, J. García-Espinosa

  prodPhD OA (2023). 8

  
  

  Abstract

  Deliverable D6.3, ‘Report on monitoring the project developments’, aims to monitor the mid-term progress of the prodPhD project. This deliverable monitors the Key Performance Indicators (KPIs) of the actions in each work package of the project and provides an overall assessment of the results of each pilot action. KPI monitoring was based on the descriptive and evaluative operationalization of the KPIs in D6.1 and the structure developed in D6.2. The KPIs corresponding to each work package were monitored by the leader of each work package in line with their operationalization in D6.1. This end of the project monitoring of the progress of the prodPhD project shows that most of the implemented activities met their targets

• D5.3 (WP5): Report on the development results of the pilot actions

  E. Sanz, P. Alonso, J. García-Espinosa

  prodPhD OA (2023). 7

  
  

  Abstract

  Deliverable D5.3, ‘Report on the development results of the pilot actions,’ aims to monitor the pilot actions carried on by the partners to test the entrepreneurship courses proposed during the project. The pilots consisted on the collaborative development of entrepreneurship projects, using the ‘learning by doing’ methodology and materials developed in WP3, and were implemented by using the customized social network platform and collaborative work tools developed in WP4. The evaluation of the pilot actions was carried out using surveys directed towards the students of the courses, and technical staff. As two pilot actions were organized, two surveys were distributed: one to the students of the first demonstration action (July 2022) and one to the students of the second action (January 2023). In the case of technical staff one survey was distributed at the end of the second pilot. The results show that the course improved between the first and the second pilot. However, there are still some issues to address. Some students find it difficult to compaginated the course with their PhD duties. The partners tested the possibility of designing shorter seminars that might be easier for the students to fit in their schedules. As students’ satisfaction with the seminars was high, this might be a possibility for future courses at the PhD level

• D5.2 (WP5): Call for the Selection of Interested Students

  I. Ergas, N. Dozic, E. Sanz, P. Alonso, J. García-Espinosa

  prodPhD OA (2023). 6

  
  

  Abstract

  This document presents the actions taken under Task 5.2 “Selection of students for the demonstration actions”, to launch the call for candidates to participate in the ProdPhD pilot action and prepare the ground for their selection. This call for candidates was open to all the fields of studies of the WEGEMT associates and other collaborating universities (see Table 1) and reached an estimated number of 500 PhD candidates from 29 universities at 16 European countries. The development of the pertinent actions commenced in the end of 2021 and was completed in M19 (June 2022), where communication via e-mails, video calls, phone calls and (limited, due to covid restrictions) physical visits was utilized.
