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.
Isabel Löfgren takes us to the Stockholm high-rise suburbs to show us how art projects and transnational media intermingle with the multicultural urban reality. In this book, she discusses the architecture of her project Satellitstaden, where her artistic interventions with the satellite dishes on façades highlight the voices of its inhabitants through participatory and co-generative artistic processes. In these peripheries, satellite subjects emerge, orbiting around multiple identifications, foregrounding the notion of spatial justice, the subaltern and the importance of grassroots movements.The book outlines a philosophy of hospitality in response to the turn in Europe against refugees, which Löfgren considers to be a crisis of hospitality, not a crisis of migration. Löfgren discusses the ethics that govern the relationship between guest and host, the self and Other. Who has the right to belong? On what terms? She argues for a hospitable turn in art, urban planning and media, in which guest-host relationships are performed, mediated and problematized.We urgently need to re-imagine the ethics of hospitality and habitability for the near future. The 2020 pandemic forces us to reassess our philosophy and practice of human contact, re-engineering how we relate to the Other, and what hospitality means in the face of a global halt.Isabel Löfgren is a Swedish-Brazilian artist, researcher and educator based in Stockholm and Rio de Janeiro. She is currently working at the Media and Communication Studies Department at Södertörn University in Sweden, next to her artistic practice. Her research interests include cultural politics, aesthetics, and the philosophy of diaspora in the fields of contemporary art, media philosophy, and media activism.

At this moment, no method is available to objectively estimate the temperature to which skeletal remains have been exposed during a fire. Estimating this temperature can provide crucial information in a legal investigation. Exposure of bone to heat results in observable and measurable changes, including a change in colour. To determine the exposure temperature of experimental bone samples, heat related changes in colour were systemically studied by means of image analysis. In total 1138 samples of fresh human long bone diaphysis and epiphysis, varying in size, were subjected to heat ranging from room temperature to 900 °C for various durations and in different media. The samples were scanned with a calibrated flatbed scanner and photographed with a Digital Single Lens Reflex camera. Red, Green, Blue values and Lightness, A-, and B-coordinates were collected for statistical analysis. Cluster analysis showed that discriminating thresholds for Lightness and B-coordinate could be defined and used to construct a model of decision rules. This model enables the user to differentiate between seven different temperature clusters with relatively high precision and accuracy. The proposed decision model provides an objective, robust and non-destructive method for estimating the exposure temperature of heated bone samples.
