BedBasedEcho
No full textThe core challenge of the BedBasedEcho BEP project is to create an algorithm to find the heart, and apply it on a robotic echocardiography solution. The team has found multiple complex solutions that are related to this problem, and has extracted useful information from these solutions to apply to this problem. However, some of these complex solutions were too complex, causing the team to run out of physical resources, or to have the solution fail entirely. By taking a step back, and simplifying the solution, the team has managed to create a system that performs marginally better than the complex solutions. The designed product consists of three major components: the data gathering, the learning, and the deployment. When used in this order, the result is an algorithm that can predict which way it should move to gain the optimal view of the heart. The algorithm will be used as a component in a larger automated echocardiography system. Ultimately, the algorithm showed promise by autonomously finding a good view of the heart.Bachelor End ProjectComputer Science and Engineerin

Architectuur als luisteroefening
No full textAs part of The Persistence of Questioning, critical reflections for the future: ‘What is the state of architectural culture?’, Sereh Mandias explains why she – together with Elsbeth Ronner – launched the narrative podcast Windoog, her reasons for engaging in architectural criticism without using images, and the importance of architectural criticism that does not focus on the object.Situated Architectur
Modelling of magnetic structure using interior point optimization given exchange parameters
No full textIn this report, a model is presented to alleviate some of the computational work that goes into the effort of finding the magnetic properties of magnetocaloric materials. The model utilizes an interior point optimization routine to solve for the minimal exchange energy configuration of a system, given the exchange interactions of the material. The model is tested against four materials (Ni, MnO, Fe\textsubscript{2}P and Mn\textsubscript{2}Sb). For Ni and MnO, the exchange interactions are also computed. Three iterations of the model are compared. The base model, which only considers exchange interactions inside a chosen supercell, the base model with the inclusion of boundary conditions, and the base model with boundary conditions and the addition of an algorithm to find optimal solutions. \\ The algorithm analyzes the found results by the optimization routine, and if the result is considered not properly symmetric, runs the optimization routine another time, from a symmetrical starting point obtained from the outcome of the previous run. \\ In all versions of the model, effectiveness (percent of runs that resulted in the optimal configuration) and average run times were recorded. Three initialization methods for the model were used, and also tested for their effectiveness. For the algorithm, a parameter is introduced that changes the size of some of the moments for the new starting points. Six different values for were tested for their effectiveness against a test set of suboptimal solutions. The model with the addition of boundary conditions and the algorithm performed the best out of the three iterations of the model, with an effectiveness of 99.895\%, and an average run time ranging from 0.62 s for 222 Ni, to 94.64 s for 333 Fe\textsubscript{2}P, in the case of . To conclude, the model with the inclusion of the boundary conditions and the algorithm proves to be a robust method to evaluate the magnetic configuration of a material, especially for smaller systems.Applied Science
Empowering Patient-Centered Care:AI-Driven Pre-Visit Tool to Enhance Patient Engagement and Diagnostic Accuracy
No full textClinician Attitudes Towards Telemonitoring for Heart Failure Care:Opportunities for Design Research
No full textTelemonitoring (TM) systems are not widely used by Dutch Heart Failure (HF) clinics and previous research provides inconclusive evidence for their effectiveness in HF care. To understand the underlying causes, we conducted an interview study with a purposive sample of eight medical professionals regarding their expectations and experiences towards TM systems. A qualitative analysis of the interviews showed that the expectation of HF clinicians that TM reduces their workload is not met. From the interviews, relatively unknown and understudied design implications were defined to serve as opportunities for research through design to improve TM systems for HF care. The design implications were categorized by the themes 'ineffective user interaction', 'one size does not fit all', and 'sharing the load'.</p
Ecologie & Esthetiek
No full textIn recent decades, the field of architecture has witnessed a fundamental shift under the banner of ‘ecology’: from the innovation in energy technologies to the use of circular materials and climate-neutral building solutions – today, more than ever, the construction of a building seems to be dominated by an ecological awareness. At the same time, such sustainable thinking often places ecological questions outside of the design itself, in the hands of experts and within the logic of quantitative calculation, while the building disappears into the ephemerality of life cycles and network models.By focusing on the intersection between ecology and aesthetics in architecture, however, this issue of OASE situates the thinking about such issues at the heart of the discipline. It asks: how do ecological questions materialise in architecture? And what aesthetic practices are able to shape the perception of these ecological questions? Through a series of concrete projects, the contributions in this issue explore the field of tension between architectural aesthetics and issues of energy, technology and materiality. Ecological practices in architecture must not only be effective in providing solutions, but inevitably raise questions of beauty, affection and perception as well.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Situated Architectur
