Abstract
Cascade control is among the mostly used process control systems single-loop performance enhancers. The simultaneous design of series cascade controllers can be a challenging problem, due to the primary and secondary loops interaction. In this paper a swarm based technique is proposed to simultaneously design series cascaded proportional integral and derivative controllers. The design is based on the integral absolute primary error minimization, subjected to vector margins constraints both for the secondary and primary loops. Simulation results are presented to illustrate the merits of the proposed technique. © 2018 IEEE.

Abstract
The use of technology in cultural heritage sites, like virtual reconstructions, has become a common solution to improve the communication between these spaces and their visitors. The amount of virtual information is flexible and it depends on what it is intended to transmit. Since humans perceive the world with different senses and in real-time, it is being noticeable the emergence of several applications using multisensory elements. Despite the implementations and related evaluations being scarce, the more recent studies depicts that this technology prize and enhance users' experiences when more stimuli are exploited. This paper presents a survey related to the recent studies made in this context, in order to identify the actual scope of multisensory experiences in cultural heritage sites.

Abstract
The digitalization advent is characterized by the increasing availability of huge amounts of data that allows to generate new knowledge to support decision-making, problem solving and process optimization. The successful implementation of this digital transformation strongly depends on the skills and competences that professionals can have in the different dimensions of the multidisciplinary vision associated to the data scientist profile. This paper describes a study, conducted under the scope of the Da.Re Erasmus+ project, that surveys the existing trainings paths dedicated to the academic education of data scientists and the required hard and soft skills of the job offers for these professionals. The survey covers three countries of the project consortium, namely Portugal, Italy and UK.

Abstract
This article is a description of a growing community and movement taking place in Portugal related to open innovation. The testimonies of two principal promoters as well as the views of two career academics were gathered. Herein, the process is described whereby real corporate problems felt in industry and requiring a solution are brought for discussion and resolution by a community of motivated problem-solvers, who were carefully chosen for their skills and capabilities. Can this initiative become a mass phenomenon and can it be built up to attract [paying and sponsoring] corporations across Europe and from different continents? How can the events evolve to become mainstream? What capabilities and promotion are necessary forthat to occur? The promoters involved are entrepreneurs located in central Portugal and are seen to be forward-thinkers disrupting how innovation is seen and approached. In a society geared towards services and tourism the team is seeking to bring open innovation to the fore in a country also considered to be very creative and not lacking in creative talent - but which on the other hand is very traditional, collectivist, hierarchical, consensus-seeking, and where innovation may be resisted and change viewed with suspicion. In a 72-hour time frame where problem-solving participants are invited and gathered at a physical venue individuals surpass themselves and experience team work in a setting where all logistics issues are previously carefully thought out and taken care of - so as to provide for the best problem-solving environment possible. The open innovation initiatives (called Hackathons) involve the following: defining the challenges (we want challenges that define goals and purposes but that are open enough to let the team build something creative), defining the fit (each candidate can apply as a team or individually; candidates select their preferred area); building teams (the candidates are free to change teams and can even propose their own challenges; we encourage communication between the team elements and also the mentors). A three-day Hackathon involves: creating a team spirit; constant feedback; building an MVP (Minimum Viable Product); learning new things; sharing is caring.
