BACKGROUND: ICT based solutions are increasingly introduced for active and healthy ageing. In this context continuous monitoring of older adults with domestic sensor systems has been suggested to provide important information about their functional health. However, there is not yet a solid model for the interpretation of the sensor data.OBJECTIVES: The aim of our study is to define a set of predictors of functional health that can be measured with domestic sensors and to determine thresholds that identify relevant changes in these predictors.METHODS: On the basis of literature we develop a model that relates functional health predictors to features derived from sensor data. The parameters of this model are determined on the basis of a study among health experts (n = 38). The use of the full model is illustrated with three cases.RESULTS: We identified 25 predictors and their attributes. For 12 of them that can be measured with passive infrared motion sensors we determined their parameters: the attribute thresholds and the urgency thresholds.CONCLUSIONS: With the parametrized predictors in the model, domestic sensors can be deployed to assess functional health in a standardized way. Three case examples showed how the model can be used as a screening instrument for functional decline.

Higher Education Institutions (HEIs) are dedicated to the professionalization of human capital; to accomplish this, the link with the productive sector is an active component that must be strengthened through formal mechanisms. The purpose of this paper is to estimate the relationships and effects from the Institutional Framework (IF), as well as from the independent variables in the context of linking HEI with the industrial sector. Survey data were collected from 47 HEIs in the Northwest of Mexico; a mixed research approach was applied and analyzed through the partial least-squares structural equations modeling (PLS-SEM) technique. Although the IF is identified as a relevant aspect for the model, this is not a problem for Mexican HEIs, since the analysis reflects a solid legal framework regarding the common basic levels and research. The main impact for experts who carry out research activities is that the route to creating, maintaining, and promoting integrated academic, technical, and administrative personnel as a specialized work team is not achieved. The main factor that does not contribute for researchers who carry out research activities is that the route to integrating (creating-maintaining-promoting) academic, technical, and administrative personnel as a specialized work team is not achieved. One finding is that the informants agree with the existing stimuli that are not aimed at research linked to the industrial sector and problem-solving through applied research. There is a need for retaining the groups of researchers to help make the benefits for the industry clear by offering advanced linkage levels.

Within European cities, entrepreneurs engage in private and public collaborative initiatives that work towards reducing local solid waste streams (Futurium, 2019). Furniture and interior design products account for nearly 50% of these waste streams, making them a key priority on the EU agenda to prevent climate change (Vanacore et al, 2021). New legislation to extend producer responsibility and reduce waste incineration is developing on a national level (PBL, 2021) and collaborative initiatives for urban upcycling are emerging (Ministerie I&W, 2023; Futurium, 2019). Business models to support upcycling are evolving, but their configuration and effectiveness is little understood.

Power Quality, ofwel de kwaliteit van spanning en stroom, is momenteel een veelbesproken onderwerp. Door de sterke toename van niet-lineaire en energiebesparende belastingen (denk bijv. aan spaar- en ledverlichting, computervoedingen, frequentieregelaars, solaromvormers, etc.) verslechtert de kwaliteit van de netspanning terwijl diezelfde apparatuur juist gevoeliger worden voor verstoringen. Dit heeft nadelige economische en technische gevolgen voor de levensduur, efficiëntie, betrouwbaarheid en veiligheid van zowel de energie infrastructuur als de aangesloten apparatuur. Het belang van Power Quality blijkt ook uit het recent aantal publicaties en conferenties op dit vakgebied. Desondanks is de technische en wetenschappelijke analyse van Power Quality problemen voornamelijk fenomenologisch van aard. Problemen worden doorgaans beschreven aan de hand van metingen. Oplossingen worden meestal gezocht in het ad hoc plaatsen van commerciële power conditioners die de spanning en stroom beogen te verbeteren. De Power Quality problemen waar MKB-er Kanters al jaren mee worstelt zijn typerend voor de vele Power Quality problemen waar MKB-er HyTEPS, marktleider in Power Quality en Energy Efficiency, dagelijks mee te maken heeft. De installaties kunnen worden doorgemeten, maar het blijft lastig om de veroorzaker(s) van het Power Quality probleem met zekerheid vast te stellen. Het is meestal niet toegestaan om ‘verdachte’ apparaten af te schakelen in dit proces. De optimale plaatsing van de power conditioner(s) blijft daarmee een open vraag. Derhalve ontstaat de dringende behoefte aan computersimulaties om de oorzaak van verstoring te analyseren en de mogelijke oplossingen te valideren. PQsim onderzoekt of middels modellering en simulatie de bron van Power Quality problemen kan worden gealloceerd zodat er efficiënt oplossingen kunnen worden ontwikkeld en toegepast. De kennisassimilatie tussen HyTEPS, Kanters, RUG en de HAN beoogt een solide basis te vormen voor een unieke systematische en regeltechnische benadering van Power Quality problemen. De verworven inzichten dienen voorts als input voor toekomstige SiA-RAAK/TKI projecten.
