Materialen - Toegepast in design en interieur [in scène gezet] University College Ghent Abstract: Het doel van het PWO M-tdi is het onderzoeken van een aantal “interessante” nieuwe materialen met toepassingspotentie voor design en interieurtoepassingen.Het levensvatbaar maken van een prototype (of reeks van prototypes) binnen het concrete werkveld van design en interieur in de zo breedst mogelijke context. De ontworpen producten komen tot stand door tijdens het ontwerpproces te toetsen aan een vooropgesteld eisenpakket. Dit eisenpakket omvat onder andere volgende aspecten: - flexibele aanpasbaarheid aan verschillende culturen;- gevoelsmatige herkenbaarheid en toegankelijkheid voor verschillende culturen- vormelijke moduleerbaarheid naar diverse functies- productdifferentiatie die telkens kan aangepast worden via demontage en wedersamenstelling tot een nieuw geheel met een andere vorm, uitzicht en gebruiksdoel. (bv. Binnenste buiten keren, het uitzicht van houten stoel wordt uitzicht van metalen tafel, …enz.)- polyvalentie naar verschillende gebruiksmogelijkheden- individuele aanpasbaarheid met een uniforme materiële cultuur- zelfbouwmogelijkheid, startend vanaf basiscomponenten, uitbreidbaar met secundaire componenten tot een gepersonaliseerde gebruiksfunctie of een esthetische behoefte.- de graad van de duurzaamheid van de toepassingen- mate van de biologische afbreekbaarheid- de mate van recycleerbaarheid- het combineren van zowel affectieve eigenschappen als functioneel mechanische eigenschappen.
Ondanks het feit dat de materialen en producten van deze primaire bedrijven veel potentie voor interieur of designtoepassingen kunnen hebben, blijkt echter dat deze producenten zich enkel richten op industriële, niet-creatieve, niet-esthetische, niet-cultuurgerelateerde eindproducten. Ze bekommeren zich hoofdzakelijk over de “technologische en economische context” van hun materiaal of hun productieproces en niet zozeer over de eigenschappen die aangewezen zijn en noodzakelijk voor het succes van designtoepassingen (vb: het tactiele van de oppervlaktebehandeling, de esthetische gewaarwording die ontstaat vanuit de ‘materiaalvorming’, het irrationeel motorische van een materiaalcombinatie e.d.). Bovendien bezitten producenten weinig realistische ideevinding of originele verbeeldingskracht om nieuwe concepten te kunnen ontwikkelen voor de interieuren designsector.

An activity-based approach for surveying and modelling travel behaviour. Vrije Universiteit Brussel Abstract: The importance of the transportation area was evidenced by a report from several international organisations, which stated that the demand for transport services is expected to grow considerably as incomes rise, the trend toward urbanization continues and the process of globalisation moves forward. In order to meet this rising demand and because governments cannot afford to allow transport constraints to have a negative impact on the future competitiveness of their products, considerable future long-term investments are indispensable. In order to better guide and substantiate decisions of transportation planners, the use of traffic and transportation models is advocated. From an international research perspective, activity-based transportation models have set the standard for modelling travel demand. Despite the clear advantages of this type of models, they havent however been put into practice in Flanders. This project, coördinated by Prof. Geert Wets, director of IMOB (LUC), intends to develop an activity-based transportationmodel for Flanders. Its innovative in that it introduces computer-aided instruments for data collection on travel behaviour. Respondents travel behaviour will be recorded by a GPS-aid and questionned by computer. The model wil also be dynamic, so to more easily adapt to sudden changes in activities. The specific worktask of TOR consists in exploring how time budget data can be incorporated in the process of simulating travel behaviour. Besides IMOB and TOR, three other research groups participate to this project, namely the Urban Planning Group (TUEindhoven), VITO and Onderzoekscel Architectuur, Mobiliteit en Omgeving (PHL).

Co-existence and traceability of GMO and non-GMO in food supply chains University College Ghent Abstract: In de toekomst zullen steeds meer GGO's op de Europese markt toegelaten worden. Dit project heeft als doel de stakeholders van de food en feed chain te voorzien van een centraal beslissings- en ondersteunend systeem op basis van reële tools, methoden, modellen en richtlijnen. Het Co-Extra project zal hierbij methodes bestuderen en valideren voor biologische expansiebeperking, de supply chain modelleren en praktische tools en mehtodes ter beschikking stelllen om een co-existentie systeem te implementeren. Daarnaast zullen GGO-detectiemehtodes ontwikkeld en geïntegreerd worden, zullen sampling plans ontwikkeld worden en nieuwe technieken gezocht worden voor de multiplex detectie van nog niet goedgekeurde GGO's. Co-Extra bestudeert tevens de meest aangewezen informatie structuur en de bijhorende management flow om een betrouwbare en kostefficiënte traceerbaarheid te garanderen. Alle methodes en tools zullen bestudeerd en ontwikkeld worden vanuit zowel een technisch als een economisch en wetgevend oogpunt. Het Departement BIOT participeert in twee werkpaketten in dit project. Een eerste werkpakket heeft als doel de supply chains van verschillende food en feed keten te karakteriseren in al haar componenten met betrekking tot de coexistentie van GGO en niet-GGO stromen. Dit houdt een diepgaande identificatie in van de biologische, sociale en economische drijfkrachten van de desbetreffende ketens. Dit moet leiden tot de ontwikkeling van representatieve modellen die hot spot situaties kunnen identificeren en verschillende scenarios rond traceerbaarheid en co-existentie kunnen voorspellen. Het departement BIOT spitst zich hier in het bijzonder toe op de aanvoer en verwerking van sojaproducten in de diervoeder keten.Het tweede werkpakket waarin het departement BIOT betrokken is binnen Coextra heeft als doel de kostenstructuur van bovenvermelde supply chains te bestuderen om alzo de kost en/of batenin te schatten die co-existentie met zich mee kan brengen.

Studie van de structuur, stabiliteit en verwerking van fantasiegarens voor een creatieve textielindustrie University College Ghent Abstract: De rendabilteit van Vlaamse KMO's binnen de textielnijverheid wordt in belangrijke mate bepaald door innovatie en ontwikkeling van nieuwe producten. Spinners brengen nieuwe soorten garens op de markt die in het weefsel speciale effecten geven. Door de combinatie van weefof breistructuren en nieuwe garens ontwikkelen deze producten nieuwe creaties. Dit project impliceert in een eerste fase dan ook het uitvoeren van een gerichte studie rond fantasiegarens om een doorbraak te forceren van deze exotische garenstructuren in de textielindustrie(kledingtextiel en interieurtextiel). Het voorspellen van de fysische eigenschappen van fantasiegarens (garenparameters) i.f.v. de machineparameters is één van de doelstellingen van dit project. Het onderzoeksproject zal per fase opgedeeld worden in deelprojecten afhankelijk van het aantal technieken die de fantasiegarenspinmachine aankan. Het is de bedoeling om de fysische parameters van de verschillende fantasiegarens op te meten en de verbanden te leggen met de machineparameters voor de productie van fantasiegarens en de machineparameters voor de verwerking van fantasiegarens. Voor wevers en andere producenten van textielmateriaal is het maken van stalen een ultieme test voor het al dan niet slagen van de ontwerpen. In een tweede fase is het de bedoeling simulaties te maken, op basis van de ontwikkelde garens, van weefsels en/of breisels met speciale simulatiesoftware. Deze simulaties kunnen bijdragen tot een gevoelige vermindering van het maken van stalen. In een derde fase ten slotte zullen deze simulaties geweven en/of gebreid worden om na te gaan in hoeverre de simulaties de werkelijkheid benaderen. Elke fase wordt steeds op dezelfde manier ingedeeld op basis van de deelprojecten in fase één. De meerwaarde van het project situeert zich op het vlak van dienstverlening voor bedrijven, het ontwikkelen van kennis over fantasiegarens, het opbouwen van expertise binnen de Hogeschool Gent dat voor dit project als uniek binnen België mag beschouwd worden. Tevens biedt het de mogelijheid tot het uitvoeren van afstudeerprojecten binnen de opleiding van de vakgroep textiel. Voor het onderwijs is het toestel zeer nuttig als demonstratiemateriaal voor de opleidingsonderdelen spinnerijtechnologie, weverijtechnologie en breitechnologie.

Welcome Class for non-native newcomers (SO): basic principles of Dutch for newcomers. Universiteit Hasselt Abstract: Early 90s there was a growing realization that the number of foreign language students in the primary and secondary educationn due to the stream of refugees and migration, was increasing and would not stop. Therefore, the reception classes for newcomers (OKAN-class) was established. All young people between 12 and 18 years who have recently arrived in Flanders or Brussels and choose for Dutch education, can in separate classes for one school year,so they can learn Dutch as soon as possible. The objective is to let them enter in the education and discipline that most closely matches their individual capacities. In secondary education, the reception education exists of two parts: for one thing a reception year and for another the flow to and relief in the regular education. The reception year is very much focused on the acquisition of Dutch. For this reason, excluding the teaching hours of religion or non-denominational ethics, culture and religion or cultural considerations, in general, all teaching hours are used to teach Dutch. From the 2006-2007 school year,in the context of the professionalization and the nature of the course Dutch, a new general course was created in the reception education: 'English for newcomers'.

Minimizing the radiation damage in Ni-Ti-based TEM samples prepared by ion milling techniques. University of Antwerp Abstract: Classical electro-polishing methods have been already for a long time insufficient to produce all TEM samples, but now they do not even suffice for alloys. One then turns to the alternative of ion milling, but this induces a lot of damage to the remaining material. In order to minimize this damage, a dedicated approach has to be made, for which the experience from intentional radiations is certainly a big advantage.

SUBSTRATE NOISE COUPLING IN ANALOG/RF SYSTEMS Vrije Universiteit Brussel Abstract: Rising integration increases the on-chip interference and causes systems to malfunction. We propose a way to model this phenomenon and diminish its effects. The possibilities of 3D-stacking are analyzed. Context The consumer electronic market is mainly driven by cost reduction, which is facilitated by the increasing miniaturization of the transistors. More and more functionality is therefore integrated on the same die. This leads to the proliferation of single-chip radio implementations which are also called Systems-on-Chip (SoC). One of the most important drawbacks of such an implementation is the substrate coupling, an on-chip interference which is caused by the fast switching of the digital circuitry and is transported by the common substrate. This
interfering signal is injected into the substrate, propagates through the common substrate (this is why it is called substrate noise) and finally couples into the sensitive analog/RF receivers residing on the same die. This perturbation can severely affect the performance of these radios and can even lead to malfunction. Goal The purpose of this work is to give the analog designer a deep understanding about how substrate noise propagates through the substrate and how it couples into the analog circuitry. Method The propagation of substrate noise is complex and depends on the circuit layout. Therefore we propose to use a 3D field solver to predict the propagation of substrate noise. The isolation between the digital and analog circuitry can be enhanced by the use of guard rings. Different types of guard rings are investigated and guidelines are provided to help the designer to choose the guard ring that fits the best to his needs. Further, the different substrate noise coupling mechanisms in a single active device are revealed. Measurements and simulations point out that the importance of the coupling mechanism is determined by the resistance of the ground interconnect. To guarantee first silicon pass, it is mandatory to accurately predict the impact of substrate noise into the sensitive analog circuitry. To this end, a methodology is presented that combines both the strengths of the emerging 3D field solvers and the circuit simulators. A large number of examples such as a 5GHz wideband receiver are modeled with this methodology. All the examples are successfully validated with measurements. Finally, this PhD has explored the opportunity of 3D-stacking to reduce the substrate noise coupling. Measurements and simulations have pointed out that a 3D-SoC offers 10x better substrate noise isolation than a traditional 2D-SoC. 2 Organisations: • Electricity

RADIOTECT : Ultra wideband radio application for localisation of hidden people and detection of unauthorised objects. Vrije Universiteit Brussel Abstract: The RADIOTECT project was completed in June 2009. The project helped support four SMEs to become more innovative, to adapt their technologies, to develop transnational cooperation and to extend their cooperative relations. This was achieved in the specific area of wideband radio for the detection of hidden people and objects. All the SMEs are innovative in their own right and together they wish to bring new products to the market utilising a world patented technique for ultra wideband technology called the Maximum Length Binary Sequence technology and other specific knowledge. The SMEs required the support of leading universities as RTD providers in order to develop the best data extraction techniques for through wall and through dress imaging products, to advise on hardware development and in general to give a "push" to the development process with their expertise and capacity. The SMEs intend to sell products with results from the project to the security, rescue and other markets. There are a handful of organisations in the world that provide ultra wideband products most of which are in the USA. The support to the SMEs in the project helped to ensure that Europe continues to capitalise on the knowledge and expertise which it has for ultra wideband technology which is proving to be more and more suitable for varying applications.

ESTIMATE: A behavioural analysis and examination of environmental implications of multimodal transportation choice Vrije Universiteit Brussel Abstract: In recent years awareness has grown that current aggregate urban development trends, as manifested in land-use patterns and transport systems, are simply not sustainable or desirable. An undeniable driving force behind these unsustainable development trends is the seemingly unbounded availability and popularity of the private car and the travel behaviour associated with car travel. Rising concerns over the continual growth of car use and the increasingly intolerable externalities have generated particular interest in how transport planning policies might at least moderate the pressures in growth in personal mobility and support the principles of sustainable development. For more sustainable travel behaviour to occur, transport planning policies might rely upon other forms of motorized transport which may act as a substitute for car-travel. Public transport is then an obvious choice, but it is important to have this type of transport clearly integrated in a well coordinated multimodal transport chain. For any multimodal transport chain to support the principles of sustainable development, it should (i) fulfil a social development role, it should (ii) support economic growth and development, and it should have (iii) environmental benefits. It is our goal within this project to pay attention to these three pillars of the concept of sustainability within a context of multimodal transport. A well established multimodal transport chain and public transport supports in a base-level mobility for all and overcomes social exclusion. However, the main question with respect to the fulfilment of a social development role is whether multimodal transport serves the interaction requirements of individuals. In order to understand the interaction requirement of individuals (and households) and of the forces at work on these interaction requirements it is important to estimate the demand for travel and quantify the important (causal) factors underlying this demand. To this end, we will consider travel to be a derived demand, derived from the need of individuals and households to participate in activities. We will perform this research in a context of activity-based approaches, which do not adequately capture the impact of multimodal transport make-up on activity and travel behaviour until now. The main added value of activity-based approaches is the ability to predict how individuals respond to planning policies which are commonly referred to as travel demand management (TDM) measures. Examples of such measures may be non-travel-related such as the spreading of peak-period travelling through relaxing working, school and shopping hours, but also direct travel-related measures are possible by providing an improved spatially available public transport system, or by pricing measures such as congestion charging. These measures will be implemented in an activity-based model and its sensitivity will be tested. To examine the second principle of sustainability, we need to have a detailed overview of all the costs and benefits of various TDM-measures. For this purpose we will rely upon a social cost-benefit analysis (SCBA). The SCBA-model is based on the theory of welfare economics, according to which the welfare of a society depends on the aggregate individual utility levels of all members of that society. In order to quantify the expected reduction in congestion costs, we need to introduce the concept of value of time. Stated-preference methods, whereby hypothetical questions are posed to travellers to gain information about trade-offs they would be willing to make, are commonly used to measure these time valuations. The combination of a social cost-benefit analysis with an activity-based model is of great importance. It allows us to differentiate the environmental
effects towards time and space, enabling to calculate the environmental and congestion costs. The environmental impact of multimodal passenger traffic will be assessed with the help of a multi-modal Ecoscore passenger model based on wellto-wheel emissions. The Ecoscore rating tool allows assessing the environmental impact of vehicles with different fuels and drive trains. Different types of pollution, such as green house gasses, air quality depleting emissions and also noise pollution, as well as their impact on different damage categories, effects on human health and on ecosystems, are integrated into a single environmental indicator. The weighting factors of the model allows to take into account policy priorities. The existing Ecoscore vehicle rating tool will be adapted to allow the environmental impact assessment of travels with different transport modes.

Naaldleno: opportuniteiten en hindernissen voor de weefindustrie bij het gebruik van deze revolutionaire technologie University College Ghent Abstract: Lenoweefsels werden traditioneel geproduceerd met hevels, wat laag productief is en dus duur. Door de recente ontwikkelingen van snellere naaldlenotechnologieën is de mogelijkheid gecreëerd om lenoweefsels goedkoper te produceren en dus economisch verantwoord in te zetten op meerdere markten. Tegelijk is de nood ontstaan naar meer technisch-wetenschappelijke kennis over lenoweefstructuren. Het doel van dit onderzoeksproject is daarom om via een grondige studie van de naaldlenotechnologie de nodige kennis op te bouwen en een aantal technologische problemen op te lossen en terzelfder tijd deze kennis en oplossingen bij de bedrijven te brengen om een versnelde introductie van de naaldleno in de Vlaamse textielindustrie mogelijk te maken. De drie basispijlers waarop de groei van de markt voor lenoweefsels is gesteund zijn:
•traditionele lenoweefsels worden goedkoper geproduceerd en kunnen een hoger marktaandeel halen. •kettingbreisels zullen voor bepaalde toepassingen vervangen worden door open lenoweefsels. •gesloten weefsels met traditionele bindingen zullen voor bepaalde toepassingen vervangen worden door weefsels met lenobinding. Voor de overschakeling van hevelleno naar naaldleno moet worden onderzocht of en hoe de heveltechnologieën kunnen vervangen worden. Wanneer een doek met open structuur, een gaas of een net, een hoge stabiliteit moet hebben, m.a.w. een hoge schuifweerstand moet hebben, dan wordt dikwijls voor een kettingbreisel geopteerd. Indien de structuur van het lenoweefsel beter kan gefixeerd worden, dan ligt hier een opportuniteit voor deze weefsels. Tot op heden werd de lenotechnologie enkel gebruikt voor open weefstructuren. De hogere productiesnelheid van de naaldlenotechnologie maakt het economisch verantwoord om voor een aantal toepassingen over te schakelen van traditionele weefbindingen naar lenobindingen. Gesloten weefstructuren met lenobinding hebben echter een andere structuur dan deze gebaseerd op een traditionele binding. Daardoor kunnen een aantal fundamentele weefselparameters wijzigen. Onderzoek moet uitwijzen welke eigenschappen worden gewijzigd en vooral in welke mate. Voor de belangrijke parameter van de schuifweerstand bestaat er geen bruikbare genormeerde meetmethode die op open weefstructuren toepasbaar is. Aangezien in de meeste (potentiële) toepassingen deze schuifweerstand belangrijk is, is het een van de doelstellingen van dit project een bruikbare meetmethode alsook een mathematisch model te ontwikkelen.
