Verbinding als sleutel tot binnenstedelijke kwaliteit

Deze publicatie bevat de belangrijkste bevindingen van een verkenning van de kansen die de inzet van retail en cultuur bieden voor de ontwikkeling van kwaliteit in binnensteden. Een groot aantal gemeenten wordt geconfronteerd met vraagstukken over de herinrichting van zowel hun kernen als de omliggende wijken en gebieden. Tegelijkertijd geldt dat zowel retail als cultuur zich voor belangrijke uitdagingen gesteld zien in het postcorona tijdperk. In ‘Verbinding als sleutel tot stedelijke kwaliteit’ wordt de problematiek uiteengezet, de kansen en mogelijkheden van een ontwerpbenadering toegelicht en een tweetal cases behandeld: Hart van Zuid in Rotterdam en Osdorpplein in Amsterdam.

SIM-OPT in the Loop: Algorithmic Framework for Solving Airport Capacity Problems

The following paper presents an innovative approach for dealing with complex capacity problems in aviation. We introduce a sliding window framework composed by an optimization method with a simulation component. By applying this framework in diverse problems that are dependent on time it is possible to find feasible and close-to-reality solutions in shorter time than the ones that could be achieved by evaluating the problem in the complete time-horizon. The framework can be applied to solve diverse problems in aviation or similar industries. We exemplify the approach with a model of Paris Charles de Gaulle Airport in France.

Voorbeeldboekje kleinschalig binnenstedelijk gebied

De SEV (Stuurgroep Experimenten Volkshuisvesting) voert in opdracht van VROM/WWI het programma Experiment Energiesprong Gebouwde Omgeving uit.Met dit programma moet de SEV de aanpak van energiebesparing in de gebouwde omgeving in een hogere versnelling zetten. Vooral in bestaand bebouwd gebied is het lastig om op grote schaal een energiesprong te maken. En toch is daar de grootste winst te halen: oude huizen, kantoren en winkels zijn energetisch vaak zo lek als een mandje, terwijl de eigenaren meestal niet de gelegenheid, de kennis, het geld of de motivatie hebben om er iets aan te doen. Losse initiatieven kunnen helpen, maar zijn uiteindelijk niet genoeg om een echte energiesprong te maken.

Nudging autonomous learning behavior: three field experiments.

Autonomous learning behavior is an important skill for students, but they often do not master it sufficiently. We investigated the potential of nudging as a teaching strategy in tertiary education to support three important autonomous learning behaviors: planning, preparing for class, and asking questions. Nudging is a strategy originating from behavioral economics used to influence behavior by changing the environment, and consists of altering the choice environment to steer human behavior. In this study, three nudges were designed by researchers in co-creation with teachers. A video booth to support planning behavior (n = 95), a checklist to support class preparation (n = 148), and a goal-setting nudge to encourage students to ask questions during class (n = 162) were tested in three field experiments in teachers’ classrooms with students in tertiary education in the Netherlands. A mixed-effects model approach revealed a positive effect of the goal-setting nudge on students’ grades and a marginal positive effect on the number of questions asked by students. Additionally, evidence for increased self-reported planning behavior was found in the video booth group—but no increase in deadlines met. No significant effects were found for the checklist. We conclude that, for some autonomous learning behaviors, primarily asking questions, nudging has potential as an easy, effective teaching strategy.

A framework for stakeholders’ involvement in digital productions for cultural heritage tourism.

This paper proposes a new framework for the production and development of immersive and playful technologies in cultural heritage in which different stakeholders such as users and local communities are involved early on in the product development chain. We believe that an early stage of co-creation in the design process produces a clear understanding of what users struggle with, facilitates the creation of community ownership and helps in better defining the design challenge at hand. We show that adopting such a framework has several direct and indirect benefits, including a deeper sense of site and product ownership as direct benefits to the individual, and the creation and growth of tangential economies to the community.

Supporting Learning Analytics Adoption

Although learning analytics benefit learning, its uptake by higher educational institutions remains low. Adopting learning analytics is a complex undertaking, and higher educational institutions lack insight into how to build organizational capabilities to successfully adopt learning analytics at scale. This paper describes the ex-post evaluation of a capability model for learning analytics via a mixed-method approach. The model intends to help practitioners such as program managers, policymakers, and senior management by providing them a comprehensive overview of necessary capabilities and their operationalization. Qualitative data were collected during pluralistic walk-throughs with 26 participants at five educational institutions and a group discussion with seven learning analytics experts. Quantitative data about the model’s perceived usefulness and ease-of-use was collected via a survey (n = 23). The study’s outcomes show that the model helps practitioners to plan learning analytics adoption at their higher educational institutions. The study also shows the applicability of pluralistic walk-throughs as a method for ex-post evaluation of Design Science Research artefacts.

Fascinating Photonics

De missie van het lectoraat Fotonica is om een bijdrage te leveren aan een gezonde wereld en een duurzame economie door het toepasbaar maken van fotonicatechnologie in de praktijk. Ook draagt het lectoraat bij aan het opleiden van professionals op het gebied van fotonica, wat een voorwaarde is om de ambities van deze groeisector waar te kunnen maken. Het fotonica-onderzoek richt zich op de toepassingsgebieden Hightech Industrie, Agri & Food, Energie & Klimaat, Gezondheid en Mobiliteit. Digitale technologie speelt in de ontwikkeling van deze gebieden een grote rol, waarbij fotonica op grote schaal wordt ingezet voor het verkrijgen van digitale data. Sleutelwoorden voor het onderzoek zijn spectroscopie, metrologie en afbeelding. Het toepassen van optische sensoren, zoals spectrometers of glasvezel-gebaseerde sensoren, speelt hierbij een centrale rol. De lijfspreuk van de natuurkundige Heike Kamerlingh Onnes ‘door meten tot weten’, aangevuld met ‘door weten tot handelen’, is dan ook een leidraad voor het lectoraat.

Performance Characterization of an Illumination-Based Low-Cost Multispectral Camera

Spectral imaging has many applications, from methane detection using satellites to disease detection on crops. However, spectral cameras remain a costly solution ranging from 10 thousand to 100 thousand euros for the hardware alone. Here, we present a low-cost multispectral camera (LC-MSC) with 64 LEDs in eight different colors and a monochrome camera with a hardware cost of 340 euros. Our prototype reproduces spectra accurately when compared to a reference spectrometer to within the spectral width of the LEDs used and the ±1σ variation over the surface of ceramic reference tiles. The mean absolute difference in reflectance is an overestimate of 0.03 for the LC-MSC as compared to a spectrometer, due to the spectral shape of the tiles. In environmental light levels of 0.5 W m−2 (bright artificial indoor lighting) our approach shows an increase in noise, but still faithfully reproduces discrete reflectance spectra over 400 nm–1000 nm. Our approach is limited in its application by LED bandwidth and availability of specific LED wavelengths. However, unlike with conventional spectral cameras, the pixel pitch of the camera itself is not limited, providing higher image resolution than typical high-end multi- and hyperspectral cameras. For sample conditions where LED illumination bands provide suitable spectral information, our LC-MSC is an interesting low-cost alternative approach to spectral imaging.
