Reinstatement of memory-related neural activity measured with high temporal precision potentially provides a useful index for real-time monitoring of the timing of activation of memory content during cognitive processing. The utility of such an index extends to any situation where one is interested in the (relative) timing of activation of different sources of information in memory, a paradigm case of which is tracking lexical activation during language processing. Essential for this approach is that memory reinstatement effects are robust, so that their absence (in the average) definitively indicates that no lexical activation is present. We used electroencephalography to test the robustness of a reported subsequent memory finding involving reinstatement of frequency-specific entrained oscillatory brain activity during subsequent recognition. Participants learned lists of words presented on a background flickering at either 6 or 15 Hz to entrain a steady-state brain response. Target words subsequently presented on a non-flickering background that were correctly identified as previously seen exhibited reinstatement effects at both entrainment frequencies. Reliability of these statistical inferences was however critically dependent on the approach used for multiple comparisons correction. We conclude that effects are not robust enough to be used as a reliable index of lexical activation during language processing.

This publication gives an account of the Public Annotation of Cultural Heritage research project (PACE) conducted at the Crossmedialab. The project was carried out between 1 January 2008 and 31 December 2009, and was funded by the Ministry of Education, Culture, and Science. Three members of the Dutch Association of Science Centres (Vereniging Science Centra) actively participated in the execution of the project: the Utrecht University Museum, the National Museum of Natural History (Naturalis), and Museon. In addition, two more knowledge institutes participated: Novay and the Utrecht University of Applied Sciences. BMC Consultancy and Manage¬ment also took part in the project. This broad consortium has enabled us to base the project on both knowledge and experience from a practical and scientific perspective. The purpose of the PACE project was to examine the ways in which social tagging could be deployed as a tool to enrich collections, improve their acces¬sibility and to increase visitor group involvement. The museums’ guiding question for the project was: ‘When is it useful to deploy social tagging as a tool for the benefit of museums and what kind of effect can be expected from such deployment?’ For the Crossmedialab the PACE project presented a unique opportunity to conduct concrete research into the highly interesting phenomenon of social tagging with parties and experts in the field.

Together with several Dutch museums, we examined the question of whether and how social tagging could benefit these museums in disclosing specific digital collections. This led to the development of a social tagging tool (www.ikweetwatditis.nl) as a means of researching behaviour when tagging cultural objects. The results show that tagging and storytelling can help museums enrich their collections and involve their audiences.

Internet of Things (IoT) is tagging low power devices, miniaturized, with machine-readable identification tags, which are integrated with sensors to collect information and wireless technology to connect them with the Internet. These devices have a very low energy usage. Powering these devices with battery is very labor intensive, costly and tedious especially as number of nodes increases, which is in many applications, is the case. Hence the main objective of this proposal is to introduce new product called RF Colletor, in the market such that IoT devices function independent of battery. Using the suggested approach the wille be energized using Radio Frequency (RF) energy harvesting. RF Collector wirelessly capture the RF energy that is wasted in space, and re-use it again as the power source for IoT devices and hence making them autonomous of battery. The ability to harvest RF energy enables wireless charging of low-power devices in real time. This has resulting benefits to sustainability, cost reduction, product design, usability, and reliability.
Met een dringend tekort aan zowel materialen, componenten en technische personeel is de roep om ‘smart manufacturing’ luider dan ooit. ‘Smart’ staat in deze context voor: het proces flexibeler en efficiënter maken door meer op real-time data te kunnen sturen. Maar ook voor foutloos produceren van steeds kleiner wordende series. Hiervoor moeten productie- en planningsrisico’s veel beter in kaart gebracht worden. Digitalisering van het productieproces kan hierbij ondersteunen, maar bedrijven lopen regelmatig tegen integratieproblemen aan waarvoor gezocht wordt naar bedrijfs- en vendor-specifieke oplossingen en interfaces. In welke mate hier generieke lessen en kennis uitgehaald kunnen worden is vooralsnog niet duidelijk. De onderzoeksvraag van dit project is dan ook: Op welke manier kunnen methoden voor ‘tagging’, produceerbaarheidschecks en visualisatie van productiedata ontwikkeld, beschreven, gedeeld en toegepast worden binnen een grotere groep bedrijven? De checks en visualisaties zijn een opstap naar zero-defect productie. ‘Tagging’ wordt niet per se gezien als de beste of enige oplossing, maar als een laagdrempelige en decentrale vorm van integratie, die goed als opstap gebruikt kan worden naar digitaal delen van informatie in het productieproces of -keten. Een ander streven is het presenteren van informatie aan een operator, zodanig dat dit tot procesverbetering kan leiden. Het zijn interessante cases om kennis over digitalisatie te delen tussen bedrijven. Om dit te realiseren wordt er een aantal casestudies uitgevoerd bij mkb-bedrijven in de maakindustrie, waarbij een specifieke oplossing voor product-tagging & machine-dashboards gegeneraliseerd wordt naar een template met implementatiehandleiding. Vervolgens zullen onderzoekers van een andere hogeschool deze template bij een ander bedrijf implementeren. Op basis van de ‘lessons-learned’ kan de verkregen kennis publiek beschikbaar gemaakt worden in de vorm van een toolkit. Dit biedt een ontwikkelaar in een mkb-bedrijf houvast voor stapsgewijze verbetering van zijn productie- en informatieprocessen.
