Droop control is used for power management in DC grids. Based on the level of the DC grid voltage, the amount of power regulated to or from the appliance is regulated such, that power management is possible. The Universal 4 Leg is a laboratory setup for studying the functionality of a grid manager for power management. It has four independent outputs that can be regulated with pulse width modulation to control the power flow between the DC grid and for example, a rechargeable battery, solar panel or any passive load like lighting or heating.

Detecting practical problems of persons with dementia (PwD) experience at home, and advising them on solutions to facilitate aging in place are complex and challenging tasks for nurses and case managers. In this two group randomized, controlled laboratory experiment, the efficacy of a decision support application aiming to increase nurses' and case managers' confidence in clinical judgment and decision-making was tested. The participants (N = 67) assessed a case of a PwD within the problem domains: self-reliance, safety and informal care, and provided suggestions for possible solutions. Participants used either their regular procedure with (intervention group) or without the App (control group) to conduct these tasks. No statistically significant difference was found on the primary outcome measure, the overall level of confidence. However, nurses and case managers highly recommended use of the App in practice. To explain these results, more research on the potential added value of the App is needed.

The main question in this PhD thesis is: How can Business Rules Management be configured and valued in organizations? A BRM problem space framework is proposed, existing of service systems, as a solution to the BRM problems. In total 94 vendor documents and approximately 32 hours of semi-structured interviews were analyzed. This analysis revealed nine individual service systems, in casu elicitation, design, verification, validation, deployment, execution, monitor, audit, and version. In the second part of this dissertation, BRM is positioned in relation to BPM (Business Process Management) by means of a literature study. An extension study was conducted: a qualitative study on a list of business rules formulated by a consulting organization based on the Committee of Sponsoring Organizations of the Treadway Commission risk framework.

From the article: "The object of this paper is to explore the actual practice in project management education in the Netherlands and compare it to reference institutions and recent literature. A little over 40% of the Higher Education institutions in the Netherlands mentions PM education in programs and/or courses. A total of 264 courses, minors and programs in the Netherlands found. In reference institutions 33 courses and programs are found and 36 publications deal with actual teaching of project management in Higher Education. Comparing these sources finds traditional methods of teaching and testing, a roughly comparable focus on subjects and an unsupported high claim of learning level, while the number of credits assigned to project management is relatively small. There is a strong focus on planning without execution, which is critiqued as is the promoted Project Based Learning."

Blood draws for laboratory investigations are essential for patient management in neonatal intensive care units (NICU). When blood samples clot before analysis, they are rejected, which delays treatment decisions and necessitates repeated sampling.

This article presents and discusses an extracurricular, co-constructed programme: “The Catalyst Club” as a form of Artistic Educational Commoning (AEC). Having been developed as part of a PhD research at Minerva Art Academy (Groningen, TheNetherlands), The Catalyst Club (TCC) explored new perspectives on the education of artists and designers in a globalized world and created alternative modes of operating in higher art education. It brought together students, alumni, teachers from a range of disciplines, and external participants. During developing TCC, the author occupied a dual role as researcher and participant, working together with others in an artistic co-creative process. TCC drew on and developed the methods relating to Collaborative Autoethnography, Participatory Action Research and Artistic Research. This study presents AEC as a communal effort to build spaces for learning and experimentation. They are created through interaction and cooperation, based on social relations and the production of shared values. As such it can offer a counterbalance to the extensive individualisation, instrumentalization, and commodification of communities in higher art education. The article formulates some recommendations on how AEC can reconnect the education of artists and designers with the role of the arts in wider technological, societal, and political contexts.

With the increasing significance of the online lifeworld in the lives of adolescents, youth work must adapt its methods to support young people’s personal development and social participation in this hybrid online space. To date, there is limited knowledge on how youth workers can effectively employ methodical actions in the online environment. This paper draws on established offline youth work methods to explore their potential transferability to the online context. The research question guiding this study is: How can offline youth work methods be used in the online lifeworld to support adolescents’ developmental needs? Using the Change Laboratory method, 26 youth workers from 14 youth work organisations in the Netherlands participated in this research. The findings suggest that while offline methods provide a valuable resource, they cannot be directly transferred to the online context without adaptation. Instead, they offer a framework for seven specific methodical actions that can be adapted or developed for the online context. They are: 1) Increasing online visibility and accessibility, 2) Orienting, 3) Signalling, 4) Making contact, 5) Building meaningful relationships, 6) Assessing needs, and 7) Providing support. By identifying these seven methodical actions which are crucial for addressing the developmental needs of adolescents online, this paper contributes to the growing body of knowledge on youth work in the online lifeworld.

A unique way of teaching practical aspects of renewable energy technologies has been experimented in the University of Oldenburg since 1987. An energy laboratory (Energielabor), built in 1982 and powered by renewable energy sources, has been used for practical training, lectures and office space for the staff and students engaged in the field of renewable energy at the University. After 30 years of service, this Energielabor requires revision and needs to be rebuilt to meet the needs of present age. In this direction, as part of a module named 'Case Study', PPRE masters' students assessed the locally available renewable energy resources and estimated the energy demand for a newly proposed design for the upcoming new Energielabor. This paper presents the first results of these energy demand and resource assessments, along with highlighting the didactical concepts and motivations behind the newly proposed design.

Sedimentation devices have been widely implemented to remove suspended solids and attached pollutants from stormwater before entering surface waters. The treatment performance of these best management practices (BMPs) on fine particles is rarely investigated in a standardized way. To overcome this information gap a reliable and standardized testing procedure is formulated.Four devices have been tested on their suspended sediments removal efficiency at different discharges and particle sizes, using the newly developed standardized full scale test method. The observed removal rates of the facilities with a storage volume in the order of 1.5 m3 and settling surface around 1 m2 drop to low removal efficiencies at flow rates of 10 l/s or more. For small sized sediments (up to 63 μm) the removal efficiency is below 50%. The results of the experiments can be used to improve both the design and the dimensions of stormwater treatment devices.
