Exhibition of Work In Progress outcomes of elective course 'Mythbusters, Unfixing Histories, World Press Photo'. The course is part of the project Unfixing Histories, which is related to my PhD research, but takes the gesture of investigating histories in and with photographs as part of artistic practices to other contexts. In this case students investigate in different ways one World Press Photo winner of their choice. Final results will be presented during "Unfixing Histoires" at Platform Minerva, March/April 2018. This exhibition is part of the World Press Photo Groningen exhibition in the Synagogue in Groningen.
Abstract Background: To address the lack of social interaction and meaningful activities for persons with dementia (PWD) in nursing homes an artistic Photo-Activity was designed. The present study aims to develop a digital version of the Photo-Activity and to investigate its implementation and impact on nursing home residents with advanced dementia, and their (in)formal carers. Methods: First, within a user-participatory design, a digital-app version of the Photo-Activity will be developed and pilot-tested, in co-creation with (in)formal carers and PWD. Next, the feasibility and effectiveness of the Photo-Activity versus a control activity will be explored in a randomized controlled trial with nursing home residents (N=90), and their (in)formal carers. Residents will be offered the Photo- Activity or the control activity by (in)formal carers during one month. Measurements will be conducted by independent assessors at baseline (T0), after one month (T1) and at follow up, two weeks after T1 (T2). Qualitative and quantitative methods will be used to investigate the effects of the intervention on mood, social interaction and quality of life of the PWD, sense of competence of informal carers, empathy and personal attitude of the formal carers, and quality of the relationship between the PWD, and their (in)formal carers. In addition, a process evaluation will be carried out by means of semi-structured interviews with the participating residents and (in)formal carers. Finally, an implementation package based on the process evaluation will be developed, allowing the scaling up of the intervention to other care institutions. Discussion: Results of the trial will be available for dissemination by Spring 2023. The digital Photo-Activity is expected to promote meaningful connections between the resident with dementia, and their (in)formal carers through the facilitation of person-centered conversations.

This paper introduces the open-source Urban Belonging (UB) toolkit, designed to study place attachments through a combined digital, visual and participatory methodology that foregrounds lived experience. The core of the toolkit is the photovoice UB App, which prompts participants to document urban experiences as digital data by taking pictures of the city, annotating them, and reacting to others’ photos. The toolkit also includes an API interface and a set of scripts for converting data into visualizations and elicitation devices. The paper first describes how the app’s design specifications were co-created in a process that brought in voices from different research fields, planners from Gehl Architects, six marginalized communities, and citizen engagement professionals. Their inputs shaped decisions about what data collection the app makes possible, and how it mitigates issues of privacy and visual and spatial literacy to make the app as inclusive as possible. We document how design criteria were translated into app features, and we demonstrate how this opens new empirical opportunities for community engagement through examples of its use in the Urban Belonging project in Copenhagen. While the focus on photo capture animates participants to document experiences in a personal and situated way, metadata such as location and sentiment invites for quali-quantitative analysis of both macro trends and local contexts of people’s experiences. Further, the granularity of data makes both a demographic and post-demographic analysis possible, providing empirical ground for exploring what people have in common in what they photograph and where they walk. And, by inviting participants to react to others’ photos, the app offers a heterogeneous empirical ground, showing us how people see the city differently. We end the paper by discussing remaining challenges in the tool and provide a short guide for using it.
Many lithographically created optical components, such as photonic crystals, require the creation of periodically repeated structures [1]. The optical properties depend critically on the consistency of the shape and periodicity of the repeated structure. At the same time, the structure and its period may be similar to, or substantially below that of the optical diffraction limit, making inspection with optical microscopy difficult. Inspection tools must be able to scan an entire wafer (300 mm diameter), and identify wafers that fail to meet specifications rapidly. However, high resolution, and high throughput are often difficult to achieve simultaneously, and a compromise must be made. TeraNova is developing an optical inspection tool that can rapidly image features on wafers. Their product relies on (a) knowledge of what the features should be, and (b) a detailed and accurate model of light diffraction from the wafer surface. This combination allows deviations from features to be identified by modifying the model of the surface features until the calculated diffraction pattern matches the observed pattern. This form of microscopy—known as Fourier microscopy—has the potential to be very rapid and highly accurate. However, the solver, which calculates the wafer features from the diffraction pattern, must be very rapid and precise. To achieve this, a hardware solver will be implemented. The hardware solver must be combined with mechatronic tracking of the absolute wafer position, requiring the automatic identification of fiduciary markers. Finally, the problem of computer obsolescence in instrumentation (resulting in security weaknesses) will also be addressed by combining the digital hardware and software into a system-on-a-chip (SoC) to provide a powerful, yet secure operating environment for the microscope software.
Het KIEM High Tech project ALIGN beoogt de verbetering van fiberoptische gyroscoop (FOG)-productie door het huidige handmatige uitlijnproces van optische fibers en de lichtbron te automatiseren. In de luchtvaart, waar precisie en betrouwbaarheid cruciaal zijn, spelen FOG’s een essentiële rol bij het meten van de oriëntatieveranderingen van vliegtuigen. Een consistente productie van de FOG’s leidt tot een betrouwbaarder en veiliger vliegtuig. Hoewel het product voldoet aan de eisen die de luchtvaart stelt, veroorzaakt de huidige productiemethode variabiliteit in sensorprestaties, en men begrijpt niet volledig waarom dit gebeurt. Het consortium bestaande uit Patria, IMS, en het lectoraat Applied Nanotechnology (ANT) van Saxion wil een proof-of-concept demonstreren voor geautomatiseerde uitlijning, met de focus op fiberdetectie en manipulatie, uitlijnalgoritmes, en stabiele prestaties van het eindproduct. Het innovatieve aspect omvat het onderzoek naar geschikte automatiseringsmethoden, rekening houdend met fixatie van de optische componenten door solderen. Huidige automatiseringsoplossingen zijn duur en zijn niet altijd geschikt voor fixatie van optische componenten bij hoge temperaturen. Het projectplan omvat verschillende activiteiten, waaronder onderzoek naar fibermanipulatie en control, vision, en integratie en verificatie. Het doel is het creëren van een werkende proof-of-concept demonstrator die voldoet aan de gestelde eisen van het productieproces en het eindproduct. De kennis uit dit project wordt opgenomen in onderwijsmodules van verschillende opleidingen, en kan een opmaat zijn voor een vervolgproject in het RAAK MKB programma. Het consortium beoogt de kritische stappen in fiberoptische uitlijning te begrijpen en een geautomatiseerde oplossing te ontwikkelen voor consistente FOG-productie. Het project draagt niet alleen bij aan de luchtvaartindustrie maar heeft ook bredere toepassingen, zoals bij de uitlijning van photonic integrated circuits, waardoor het een waardevolle bijdrage levert aan de ontwikkeling van geavanceerde productieprocessen in de optische fibers-industrie.
Various companies in diagnostic testing struggle with the same “valley of death” challenge. In order to further develop their sensing application, they rely on the technological readiness of easy and reproducible read-out systems. Photonic chips can be very sensitive sensors and can be made application-specific when coated with a properly chosen bio-functionalized layer. Here the challenge lies in the optical coupling of the active components (light source and detector) to the (disposable) photonic sensor chip. For the technology to be commercially viable, the price of the disposable photonic sensor chip should be as low as possible. The coupling of light from the source to the photonic sensor chip and back to the detectors requires a positioning accuracy of less than 1 micrometer, which is a tremendous challenge. In this research proposal, we want to investigate which of the six degrees of freedom (three translational and three rotational) are the most crucial when aligning photonic sensor chips with the external active components. Knowing these degrees of freedom and their respective range we can develop and test an automated alignment tool which can realize photonic sensor chip alignment reproducibly and fully autonomously. The consortium with expertise and contributions in the value chain of photonics interfacing, system and mechanical engineering will investigate a two-step solution. This solution comprises a passive pre-alignment step (a mechanical stop determines the position), followed by an active alignment step (an algorithm moves the source to the optimal position with respect to the chip). The results will be integrated into a demonstrator that performs an automated procedure that aligns a passive photonic chip with a terminal that contains the active components. The demonstrator is successful if adequate optical coupling of the passive photonic chip with the external active components is realized fully automatically, without the need of operator intervention.
