Publicatie ter gelegenheid van het afscheid/pensioen van Henk van Leeuwen, docent Informatica en lector Ambient Intelligence bij het Saxion Kenniscentrum Design en Technologie. In deze uitgave kijkt Henk van Leeuwen, na een loopbaan van 40 jaar in het onderwijs, niet alleen terug op interessante zaken uit het verleden, maar onderkent hij ook welke drijvende krachten invloed hadden. Hierbij heeft Van Leeuwen niet gestreefd naar volledigheid. Het is een persoonlijke kijk, die berust op eigen ervaringen en die tot discussie kan prikkelen. Naast de vakinhoudelijke observaties neemt Van Leeuwen ook het hbo-informaticaonderwijs en het ICT-onderzoek onder de loep. Het begrip ‘sensing’ in de titel ’Sense and nonsense of sensing’ van deze uitgave heeft dan ook niet primair een technische betekenis. Sensing is in dit verband een manier van observeren, van snuffelen. In het ‘Informaticavak’ gebruiken we daar tal van sensoren voor. Over sensoren gaat het zeker, maar nog meer over zijn persoonlijk observeren, interpreteren van wat hij heeft opgemerkt en zijn reflectie daarop. Dat leidt tot uitspraken over zin en onzin, sense en nonsense, van wat Van Leeuwen waarneemt, nu en in het verleden. Van Leeuwen neemt de lezer mee in de ontwikkelingen van informatica zoals hij die heeft gezien en breng daarvan verslag uit. Daarbij stelt hij de vraag of we uit de lijnen die we zien in het verleden, ontwikkelingen voor de toekomst kunnen afleiden.

News media in The Netherlands show great variety in the extent and ways, in which they realize media accountability online in terms of actor transparency, product transparency and feedback opportunities online. It is suggested that even those news rooms that seem to adhere to transparency and public accountability still need to explore the functionality and application of media accountability instruments (MAI). Both in terms of potentials and pitfalls, news rooms need to consider about what they want to be transparent and in what ways. To the extent that online innovations are visible, traditional news media seem to experiment, as is the case with newsroom blogs or the project of hyper local journalism Dichtbij.nl, part of the Telegraaf Company. Various news media have on-going projects on audience participation, online applications and distribution models. However, since many projects merely aim at finding new applications, processes, platforms and business models, it remains to be seen assess whether projects are indeed reasonably innovative and feasible at the same time. The development of an online and therefore immediate, archived, personalized and interactive context, offers practical and ethical challenges to Dutch journalism. These challenges bring shifts in its role and responsibility to society. It means that changes occur in what journalists are accountable for, as well as ways in how they are accountable. The Dutch media landscape lodges various professional accountability instruments like the press council and both profession-wide and news media specific codes of ethics, but some of these instruments receive only moderate support. Proactive openness is more an exception than the rule and may well be a distinctive indicator for quality journalism. Although news media often acknowledge the importance of media accountability offline and online, they often lack the resources or courage to use them or have different priorities. This ambiguous position may indicate that in relation to media accountability online, Dutch news media are between hope and fear: that it will either improve their relationship with the public and fuel professional quality, or ask too much of resources with too little benefit.
Dames en heren, het is mij een grote eer dat u met zo velen gekomen bent om te luisteren naar mijn openbare les in het kader van mijn benoeming tot lector product design & engineering. Ik begrijp best dat u gekomen bent, want product design & engineering is belangrijk. Zonder product design & engineering was u hier tenslotte niet eens geweest. De auto, trein of bus waarmee u hier gekomen bent, zijn mede tot stand gekomen dankzij product design & engineering. Dat u mij ook achter in de zaal kunt horen, heeft u te danken aan ditzelfde vakgebied. En dat u aan het eind van deze openbare les mogelijk pijn in uw rug heeft door een oncomfortabele zit is er ook een gevolg van. Kortom: product design & engineering is een belangrijk vakgebied waarmee we in ons dagelijks bestaan voortdurend geconfronteerd worden, aangenaam of niet. Mijn voordracht valt in drieën uiteen. Eerst sta ik stil bij de titel: Van vuistbijl tot mobieltje. Aan de hand van deze objecten illustreer ik de historische achtergronden van het vakgebied product design & engineering. Daarna ga ik dieper in op het begrip ontwerpen. Het derde deel van mijn openbare les gaat over de ambitieuze plannen van de kenniskring product design & engineering. Ik sluit mijn openbare les af met het mobieltje, maar hoe blijft nog even een verrassing.
Today, embedded devices such as banking/transportation cards, car keys, and mobile phones use cryptographic techniques to protect personal information and communication. Such devices are increasingly becoming the targets of attacks trying to capture the underlying secret information, e.g., cryptographic keys. Attacks not targeting the cryptographic algorithm but its implementation are especially devastating and the best-known examples are so-called side-channel and fault injection attacks. Such attacks, often jointly coined as physical (implementation) attacks, are difficult to preclude and if the key (or other data) is recovered the device is useless. To mitigate such attacks, security evaluators use the same techniques as attackers and look for possible weaknesses in order to “fix” them before deployment. Unfortunately, the attackers’ resourcefulness on the one hand and usually a short amount of time the security evaluators have (and human errors factor) on the other hand, makes this not a fair race. Consequently, researchers are looking into possible ways of making security evaluations more reliable and faster. To that end, machine learning techniques showed to be a viable candidate although the challenge is far from solved. Our project aims at the development of automatic frameworks able to assess various potential side-channel and fault injection threats coming from diverse sources. Such systems will enable security evaluators, and above all companies producing chips for security applications, an option to find the potential weaknesses early and to assess the trade-off between making the product more secure versus making the product more implementation-friendly. To this end, we plan to use machine learning techniques coupled with novel techniques not explored before for side-channel and fault analysis. In addition, we will design new techniques specially tailored to improve the performance of this evaluation process. Our research fills the gap between what is known in academia on physical attacks and what is needed in the industry to prevent such attacks. In the end, once our frameworks become operational, they could be also a useful tool for mitigating other types of threats like ransomware or rootkits.
Structural colour (SC) is created by light interacting with regular nanostructures in angle-dependent ways resulting in vivid hues. This form of intense colouration offers commercial and industrial benefits over dyes and other pigments. Advantages include durability, efficient use of light, anti-fade properties and the potential to be created from low cost materials (e.g. cellulose fibres). SC is widely found in nature, examples include butterflies, squid, beetles, plants and even bacteria. Flavobacterium IR1 is a Gram-negative, gliding bacterium isolated from Rotterdam harbour. IR1 is able to rapidly self-assemble into a 2D photonic crystal (a form of SC) on hydrated surfaces. Colonies of IR1 are able to display intense, angle-dependent colours when illuminated with white light. The process of assembly from a disordered structure to intense hues, that reflect the ordering of the cells, is possible within 10-20 minutes. This bacterium can be stored long-term by freeze drying and then rapidly activated by hydration. We see these properties as suiting a cellular reporter system quite distinct from those on the market, SC is intended to be “the new Green Fluorescent Protein”. The ability to understand the genomics and genetics of SC is the unique selling point to be exploited in product development. We propose exploiting SC in IR1 to create microbial biosensors to detect, in the first instance, volatile compounds that are damaging to health and the environment over the long term. Examples include petroleum or plastic derivatives that cause cancer, birth defects and allergies, indicate explosives or other insidious hazards. Hoekmine, working with staff and students within the Hogeschool Utrecht and iLab, has developed the tools to do these tasks. We intend to create a freeze-dried disposable product (disposables) that, when rehydrated, allow IR1 strains to sense and report multiple hazardous vapours alerting industries and individuals to threats. The data, visible as brightly coloured patches of bacteria, will be captured and quantified by mobile phone creating a system that can be used in any location by any user without prior training. Access to advice, assay results and other information will be via a custom designed APP. This work will be performed in parallel with the creation of a business plan and market/IP investigation to prepare the ground for seed investment. The vision is to make a widely usable series of tests to allow robust environmental monitoring for all to improve the quality of life. In the future, this technology will be applied to other areas of diagnostics.
A world where technology is ubiquitous and embedded in our daily lives is becoming increasingly likely. To prepare our students to live and work in such a future, we propose to turn Saxion’s Epy-Drost building into a living lab environment. This will entail setting up and drafting the proper infrastructure and agreements to collect people’s location and building data (e.g. temperature, humidity) in Epy-Drost, and making the data appropriately available to student and research projects within Saxion. With regards to this project’s effect on education, we envision the proposal of several derived student projects which will provide students the opportunity to work with huge amounts of data and state-of-the-art natural interaction interfaces. Through these projects, students will acquire skills and knowledge that are necessary in the current and future labor-market, as well as get experience in working with topics of great importance now and in the near future. This is not only aligned with the Creative Media and Game Technologies (CMGT) study program’s new vision and focus on interactive technology, but also with many other education programs within Saxion. In terms of research, the candidate Postdoc will study if and how the data, together with the building’s infrastructure, can be leveraged to promote healthy behavior through playful strategies. In other words, whether we can persuade people in the building to be more physically active and engage more in social interactions through data-based gamification and building actuation. This fits very well with the Ambient Intelligence (AmI) research group’s agenda in Augmented Interaction, and CMGT’s User Experience line. Overall, this project will help spark and solidify lasting collaboration links between AmI and CMGT, give body to AmI’s new Augmented Interaction line, and increase Saxion’s level of education through the dissemination of knowledge between researchers, teachers and students.
