Seven college lecturers and two senior support staff were interviewed during 2021 about their experiences teaching in hybrid virtual classrooms (HVC). These technology-rich learning environments allow teachers to simultaneously teach students who are in class (on campus) and students who are joining remotely (online). There were two reasons for this choice: first, ongoing experimentation from innovative teaching staff who were already using this format before the COVID-19 pandemic; secondly, as a possible solution to restrictions on classroom size imposed by the pandemic. Challenges lecturers faced include adjusting teaching practice and lesson delivery to serve students in the class and those online equally; engaging and linking the different student groups in structured and natural interactions; overcoming technical challenges regarding audio and visual equipment; suitably configuring teaching spaces and having sufficient pedagogical and technical support to manage this complex process. A set of practical suggestions is provided. Lecturers should make reasoned choices when teaching in this format since it requires continued experimentation and practice to enhance the teaching and learning opportunities. When external factors such as classroom size restrictions are the driving force, the specific type of synchronous learning activities should be carefully considered. The structure and approach to lessons needs to be rethought to optimise the affordances of the hybrid virtual and connected classroom. The complexity of using these formats, and the additional time needed to do it properly, should not be underestimated. These findings are consistent with previous literature on this subject. An ongoing dialogue with faculty, support staff and especially students should be an integral part of any further implementation in this format.

We report research into the evolvement of a hybrid learning environment where education, companies and government successfully cooperate. This hybrid learning environment—one of the latest inventions in curriculum design—is special because it was neither intended nor planned by the parties involved. With some self-astonishment, the participants in this research experienced a growing acknowledgement of their emerging educational creation, aside from the experience of and appreciation for their cooperation and the increasing turnover. With a bricolage research approach within the scope of a rhizomatic perspective on becoming, a multivocal perspective on the evolvement of the learning environment was pursued. In emphasizing the historical evolvement of the learning environment, our findings challenge the tradition of drawing board design, accompanied by an appeal for re-appreciating professional craftsmanship. In addition, some reflections regarding the research are discussed.

TU Delft, in collaboration with Gravity Energy BV, has conducted a feasibility study on harvesting electric energy from wind and vibrations using a wobbling triboelectric nanogenerator (WTENG). Unlike conventional wind turbines, the WTENG converts wind/vibration energy into contact-separation events through a wobbling structure and unbalanced mass. Initial experimental findings demonstrated a peak power density of 1.6 W/m² under optimal conditions. Additionally, the harvester successfully charged a 3.7V lithium-ion battery with over 4.5 μA, illustrated in a self-powered light mast as a practical demonstration in collaboration with TimberLAB. This project aims to advance this research by developing a functioning prototype for public spaces, particularly lanterns, in partnership with TimberLAB and Gravity Energy. The study will explore the potential of triboelectric nanogenerators (TENG) and piezoelectric materials to optimize energy harvesting efficiency and power output. Specifically, the project will focus on improving the WTENG's output power for practical applications by optimizing parameters such as electrode dimensions and contact-separation quality. It will also explore cost-effective, commercially available materials and best fabrication/assembly strategies to simplify scalability for different length scales and power outputs. The research will proceed with the following steps: Design and Prototype Development: Create a prototype WTENG to evaluate energy harvesting efficiency and the quantity of energy harvested. A hybrid of TENG and piezoelectric materials will be designed and assessed. Optimization: Refine the system's design by considering the scaling effect and combinations of TENG-piezoelectric materials, focusing on maximizing energy efficiency (power output). This includes exploring size effects and optimal dimensions. Real-World Application Demonstration: Assess the optimized system's potential to power lanterns in close collaboration with TimberLAB, DVC Groep BV and Gravity Energy. Identify key parameters affecting the efficiency of WTENG technology and propose a roadmap for its exploitation in other applications such as public space lighting and charging.
Sinds de corona reset wordt in de culturele en creatieve sector volop geïnnoveerd om tijdelijke sluitingen en financiële verliezen te compenseren. Aanbieders van hoogwaardige culturele programma’s, zoals presentatie-instellingen en zelforganiserende collectieven, coördineren in hoog tempo digitale expositieruimtes, livestreams en online debatten, waarmee ze hun bestaande (offline en lokale) en nieuwe (online en mondiale) publiek bedienen. Soms ook tegelijkertijd, in een hybride evenement; met een beperkt live publiek én een onbeperkt aantal online bezoekers. Hoe zorgen zij dat beide groepen bij deze livecastings een gelijkwaardige ervaring hebben? En hoe benutten ze de potentie van dit opgenomen materiaal voor publicatie en blijvende publieksinteractie in hun digitaal (web)archief? Ad hoc coronaoplossingen behoeven nu toekomstbestendige doorontwikkeling. Met MKB’ers ontwikkelen we een langetermijnvisie op off/online kennisdeling van hun culturele aanbod, op voorwaarden van duurzaamheid en technologische onafhankelijkheid in het beheer en de data-opslag van hun gepubliceerde materiaal. Verregaande digitalisering en klimaatoverwegingen geven namelijk naast corona urgentie aan een visie op hybride programmering. In het onderzoek worden werkende principes ontwikkeld voor een langetermijnvisie op een hybride en kwalitatief hoogwaardig programma-aanbod, met het oog op het bedienen van nieuw en bestaand publiek na de corona reset, via participatieve livecasts van evenementen, de samenhangende verslaglegging daarvan middels publicaties die uiteindelijk in levende archieven te komen: Om het knelpunt van ‘schermmoeheid’ bij eindgebruikers van programma-aanbod te voorkomen, ontwikkelen we werkende principes in het oplossingsgebied ‘participatieve livecasting’, om de succespijler ‘gezamenlijke publiekservaring bij online evenementen’ te bewerkstelligen. Om het knelpunt van ‘gefragmenteerde informatievoorziening’ bij programma-aanbieders te voorkomen, ontwikkelen we werkende principes in het oplossingsgebied ‘hybride publicaties’, om de succespijler ‘samenhang in off/online programma-aanbod’ te bewerkstelligen. Om het knelpunt van een ‘reactieve houding’ bij programma-aanbieders te voorkomen, ontwikkelen we werkende principes in het oplossingsgebied ‘levende archieven’, om de succespijler van een ‘anticiperende houding in de werkwijze van programma-aanbieders’ te bewerkstelligen.
The Healthy Workplace monitor is being developed to monitor the health and well-being of knowledge workers in relation to the office space and their home workplace. Since the corona period, a lot has changed in the way knowledge workers work. Both offices and employees require more flexibility to carry out work in an efficient but also healthy and enjoyable way. It is important to identify office workers needs with regard to workspaces at the office and at home from a holistic view, in which mental , physical and social aspects play a role. A vital, happy employee is a productive employee.
