Abstract
This case study aims to analyze the impact of the digital transformation on Delta Cafes. To this end, a consumer survey was carried out to understand their perception of the brand, from the products to how the company works and its actions. The sample consisted of 140 participants. An attempt was also made to understand whether the participants' perceptions were independent of whether or not they were Delta Cafes customers. The chi-square test results indicate that Delta Cafes customers are more aware of the brand, both because of the coffee and because of its founder, are more aware of the social responsibility actions carried out by the company and are more involved with organizations that positively impact society. Finally, an interview was conducted with Delta's Systems Director, who has been with the company for 12 years and is currently responsible for 54 employees out of a total of around 3500 employees. The interview lasted approximately 1 h and 15 min, via Zoom. The big challenge is to automatically manage all the processes associated with finance, logistics and production. Delta is looking to digitize the whole organization, which will free people from superfluous tasks and allow them to perform others that matter more. Enterprise Resource Planning (ERP), Customer Relationship Management (CRM) and Electronic Data Interchange (EDI) have all been implemented, as well as e-commerce and m-commerce (Delta Mobile). Dehumanization and loss of human capital are a risk of digitization which Delta Cafes seeks to avoid through trainingone of the pillars of the organization.

Abstract
This paper aims to evaluate how different combinations of multisensory stimuli affect the vividness of users' mental imagery in the context of virtual tourism. To this end, a between-subjects experimental study was conducted with 94 participants, who were allocated to either a positive or a negative immersive virtual environment. The positive environment contained only pleasant multisensory stimuli, whereas the negative contained only unpleasant stimuli. For each of the virtual experiences, a multisensory treasure hunt was developed, where each object found corresponded to a planned combination of stimuli (positive or negative, accordingly). The results showed that positive stimuli involving a higher number of sensory modalities resulted in higher reported vividness. In contrast, when the same multisensory modalities were delivered with negative stimuli, vividness levels decreased - an effect we attribute to potential cognitive overload. Nevertheless, some reduced negative combinations (audiovisual with smell and audiovisual with haptics) remained effective, indicating that olfactory and haptic cues play an important role in shaping users' vividness of mental imagery, even in negative contexts.

Abstract
This study aims to explore the impact of seven dimensions of local communities’ involvement in the context of the sustainable open innovation paradigm on entrepreneurial performance considering a tri-dimensional perspective comprising turnover, innovation capacity (IC), and employability. A quantitative methodology was adopted, applying correlational analysis and hypothesis testing to a total of 296 new ventures based in European science parks. The findings indicate that only the entrepreneurial capacity of new ventures has improved, but not turnover and employment. Also, only years of experience in open innovation networks contribute to increasing the performance of entrepreneurs in their IC, but age and gender are not significant factors. This study broadens the scope of sustainable open innovation by positioning local communities as central actors rather than peripheral stakeholders. It enriches key theoretical frameworks such as Sustainable Development Goals (SDGs) and social capital theory by emphasizing community-driven innovation. Practically, it offers actionable strategies for engaging communities and guiding policymakers toward inclusive innovation policies, thereby contributing to both academic discourse and real-world impact in sustainability and innovation ecosystems.

Abstract
EMSO ERIC is a unique European distributed marine Research Infrastructure dedicated to the observation and study of the deep ocean in the long term in fixed regional areas. It provides different services of which access to its infrastructure by external users -engineers, scientists and researchers-, working both in the public and private sectors. The aim of this service, called physical access, is to facilitate access to instrumented platforms deployed at different sites across the European seas, from the seabed to the surface, in order to perform experiments in geosciences and engineering in real ocean conditions. Depending on the logistics and availability of each site, users may deploy their own platforms, instruments, systems or technologies to be tested by the existing equipment that, in this case, can provide reference measurements. Users may also deploy their own systems on the existing EMSO platforms, either in standalone mode or connected to them, receiving power and, in some cases, being able to transmit data by satellite or by cable, depending on the site. Projects requiring the use of several EMSO sites are also accepted. The host EMSO Regional Facility provides logistics and technical support in order to deploy and recover the systems, access the data and it may also offer training and co-development. EMSO ERIC launches the physical access call on a yearly basis and evaluates the received project proposals every two months. Access is free of charge and funding is available for travel, consumables, shipping, operations and hardware adaptations needed to run the project. Since 2022, when the first call was launched, ten projects with varied topics have been funded and are in different phases of execution.

Abstract
Currently Harmonic distortion is one of the most frequent disturbances present in electrical networks, with consequences at various levels. This study intends to verify the impact that this disturbance has on the behaviour of the three-phase induction motor. Therefore, the novelty of the presented work consists in the understanding and verification of the impact of individual odd harmonics in motor behaviour. As well as analysing the impact of harmonics on the performance of induction motors, this study highlights the importance of effective technical communication and international collaboration in disseminating sustainable solutions for the green transition. The results obtained clearly demonstrate that each of the harmonics acting alone has a different influence on the motor's main parameters, especially the losses and the efficiency. In fact, lower order harmonics have greater impact on the efficiency reduction, comparing to higher orders harmonics. Therefore, special attention must to be given to attenuate it. Simultaneously, it was possible to verify the influence of total harmonic distortion in several parameters, namely with respect to torque, speed, losses and efficiency. The EMTP/ATP simulation tool was used as a tool with great capacity for transients and disturbances simulation in the voltage waveform. © 2025 IEEE.
