Parallel Welding of Thermoplastic Composites Using Continuous Ultrasonic Welding

The effect of creating parallel welds in a single overlap using continuous ultrasonic welding on the weld quality has been investigated, with the goal of creating three high-quality parallel welds. To achieve this, multiple aspects were examined to understand the creation of high-quality parallel welds. The weld quality is highly influenced by a...

Designing a new vegetarian restaurant concept: Redesigning the customer experience and customer journey for the next generation of vegetarian restaurants

With the increasing evidence of the effects of our food choices on the planet it is obvious that we have to make changes in order to live sustainably. Our food production systems are responsible for 26% of the total human induced global greenhouse gas emissions, with the meat and dairy industry being responsible for over half of that. Our planet...

Recurring COVID-19 Vaccinations: What is the required performance of the vaccination system to keep the vaccination rate above a sufficient level and minimize virus spread, given uncertainties in vaccine supply and negative social influence regarding vaccinations?

The duration of protection that COVID-19 vaccines provide is still uncertain (Murray & Piot, 2021). Therefore, a possible future scenario is that the entire population will need an extra dose of a vaccine. Yearly recurring flu vaccinations take place at general practices (GP), so this might also be the case for COVID-19 vaccinations. General...

Ice-concrete bond analysis: Characterisation of ice adhe- sion strength in ice-structure interaction

In regions which experience arctic conditions, structures like offshore wind turbines, oil-platforms, light houses, piers and bridges suffer from abrasion by moving ice sheets. This results in challenging maintenance and repair works. At the ice-structure interface, several mechanisms exist which are responsible for the wear of concrete such as:...

Poetics of subtraction: An attempt to reveal pre-existing values that lead to a meaningful architectural method — contributing to the public realm within the canal area of Brussels

We think of architecture as an additive or accumulative process: a process where elements are added in order to create architecture. After you lay a brick, you lay another. But architecture can also be seen as subtractive, where portions of volume are removed to clarify an entity. In architecture school we learn how to create a building; to...

Effecten van de fysieke werkomgeving in de backoffice van de poliklinieken in het Haga Ziekenhuis: De invloed van fysieke omgevingsaspecten op de tevredenheid van medewerkers in traditionele en nieuwe werkplekinrichtingen

Unsteady Aerodynamics in the Gust and Manoeuvre Response of Flexible Aircraft

Aircraft wings are becoming more flexible, making it important to take this flexibility into account from the start of the design process. With flexible wings, unsteady (time-varying) aerodynamics becomes important. For this reason, an unsteady aerodynamics model was constructed and coupled to an aeroelastic flight mechanics tool. This allows...

Cultural Heritage 2.0: Involving stakeholders in service innovation for an audio-visual heritage service platform

Background and problem Audio-visual cultural heritage content should be preserved for our children and their children. However, currently the devices on which this material is stored suffers from decomposition. In addition to that, the content should be unlocked on a larger scale by exploiting modern technologies such as Internet and mobile...

Digital Review: Final Project Report, Final report on the project of developing the Digital Review Application

SKION is a foundation that facilitates research of children with cancer. The research consists of investigating slides and other material gotten from the treating hospitals at SKION. The results of these investigations are saved into a database, while other information gathered by SKION through forms is stored in another database. Four times a...

Prefabricage van sluizen: Een haalbare zaak?

Hoofdstuk 1 is een inleiding op het probleem: De Zuid-Willemsvaart en het Kanaal Wessem-Nederweert in Noord Brabant en Limburg bestaan ruim 150 jaar en de meeste van de in de kanalen aanwezige sluizen dateren uit de begintijd. De kanalen zijn volledig verouderd en voldoen niet meer aan de eisen welke tegenwoordig aan de waterwegen worden gesteld...
