Topio: An Open-Source Web Platform for Trading Geospatial Data

The increasing need for data trading across businesses nowadays has created a demand for data marketplaces. However, despite the intentions of both data providers and consumers, today’s data marketplaces remain mere data catalogs. We believe that marketplaces of the future require a set of value-added services, such as advanced search and...

Reusable Virtual Coach for Smoking Cessation and Physical Activity Coaching

Smoking tobacco and physical inactivity are key preventable behavioural risk factors of cardiovascular disease (CVD). Computerised coaching systems can help individuals to modify risky behaviours, thereby preventing CVD. However, most reported eHealth or computerized coaching systems are hard to reuse in slightly different settings. To provide...

OpenSense: An open-source toolbox for inertial-measurement-unit-based measurement of lower extremity kinematics over long durations

Background: The ability to measure joint kinematics in natural environments over long durations using inertial measurement units (IMUs) could enable at-home monitoring and personalized treatment of neurological and musculoskeletal disorders. However, drift, or the accumulation of error over time, inhibits the accurate measurement of movement...

Time-Adaptive Grid Hydrological Solver Using PETSc

A high-resolution hydrological solver that solves on time-adaptive grids is created. The solver uses h-refinement strategies which adapts the resolution of the grid using a posteriori measure. It is based on an open-source scientific computing library named PETSc. With the use of highly scalable time-stepping solvers provided by PETSc, an...

Space Modders: Learning from the Game Commune & the Binck Twins Case Study: Learning emancipatory practices of space modification through videogames and their introduction to the built environment

The research attempts to investigate the workings and potentialities of videogames as a medium for participatory design and practices of commoning in architecture. The analysis begins with exploring videogames as non-normative experiences and the effects of those experiences on the players which lead to the emergence of the game commune; a force...

Fast, flexible particle simulations: An introduction to MercuryDPM

We introduce the open-source package MercuryDPM, which we have been developing over the last few years. MercuryDPM is a code for discrete particle simulations. It simulates the motion of particles by applying forces and torques that stem either from external body forces, (gravity, magnetic fields, etc.) or particle interactions. The code has...

Adjoint-based 3D Shape Optimization for Turbomachinery Applications

In order to reduce the carbon foot-print of turbo-generators to global warming, a step-change in the design process is needed. Extensive CFD simulations coupled with optimization algorithms are required, resorting to novel techniques to capture the complex flow phenomena occurring in the passage. However, the computation of the optimization...

Fluid Structure Interaction Modelling of Flapping Wings: Development and Validation of a General Open-source Fluid Structure Interaction Method with Analysis of Flexible Flapping Wing Aerodynamics

Flapping wings display complex flows which can be used to generate large lift forces. Flexibility in wings is widely used by natural flyers to increase the aerodynamic performance. The influence of wing flexibility on the flow can be computed using numerical analysis with Fluid Structure Interaction (FSI). However, there is a lack of open-source...

Plugging in the handyman business: Designing an open service innovation platform around the Ford Transit

This graduation project was part of a collaboration between the Ford Motor Company and the Delft University of Technology on the topic of Service Innovation for the Light Commercial Vehicle market. The goal of the University Research project is to infuse service design into Ford’s DNA by introducing design research and service design methodology...

Generic and complete vehicle dynamic models for open-source platforms

Vehicle dynamics models are important tools for research and development within the automotive industry. The need for such models is steadily rising due to the rapid development of automated driving, as these models allow efficient design and development of the control algorithms and functions. Chalmers Revere Lab supplements research in the...
