The application of DC grids is gaining more attention in office applications. Especially since powering an office desk would not require a high power connection to the main AC grid but could be made sustainable using solar power and battery storage. This would result in fewer converters and further advanced grid utilization. In this paper, a sustainable desk power application is described that can be used for powering typical office appliances such as computers, lighting, and telephones. The desk will be powered by a solar panel and has a battery for energy storage. The applied DC grid includes droop control for power management and can either operate stand-alone or connected to other DC-desks to create a meshed-grid system. A dynamic DC nano-grid is made using multiple self-developed half-bridge circuit boards controlled by microcontrollers. This grid is monitored and controlled using a lightweight network protocol, allowing for online integration. Droop control is used to create dynamic power management, allowing automated control for power consumption and production. Digital control is used to regulate the power flow, and drive other applications, including batteries and solar panels. The practical demonstrative setup is a small-sized desktop with applications built into it, such as a lamp, wireless charging pad, and laptop charge point for devices up to 45W. User control is added in the form of an interactive remote wireless touch panel and power consumption is monitored and stored in the cloud. The paper includes a description of technical implementation as well as power consumption measurements.
In 2021, Breda University of Applied Sciences – 7,000 students in the domains of Hotel Management, Facility Management, Games, Media, Logistics, Built Environment, Leisure & Events, and Tourism –discussed the impact of the emerging developments of immersive technologies (VR, AR, AI, Digital Twins) within the sectoral industries.This project, DigiReal – Digital Realities (DR) for Smart Industries - aimed to look beyond the diversity and variety of individual use cases to develop valuable concepts and innovations in methodologies and lab infrastructure, discussing questions: how do we create, use and experience DR sensibly, meaningfully, and responsibly?This report contains a coherent summary of the project with a lot of (domain) examples and technological developments. As a result, this report contains a BUas-wide research agenda on Digital Realities with a framework of overall, generic research questions, methodologies and ecosystems. This research has been financed by Regieorgaan SIA, part of the Dutch National Funding Organisation for Scientific Research (NWO)
Worldwide, there is a growing recognition that strategic partnering between cities and universities can bring substantial benefits for both sides. The big question is how to organize such partnerships successfully. This handbook offers insights, best practices and advice for leaders in cities and universities that want to go beyond “ad hoc” projects and take the next step towards a strategic and sustainable partnership. The handbook identifies promising avenues, but also barriers and pitfalls and how to avoid them. Illustrated by a rich variety of examples from European cities, the handbook provides concrete advice on the various stages of strategic city-university collaboration. This handbook intends to provide inspiring practices and guidance to develop strategic interaction between city and university, considering the complex and layered nature of both. The focus lies on the more strategic, transformational types of collaborations, that are more complex.
