This paper combines density-based topology optimization (TO) with a “contact aware” shape optimization (SO) which combines the design freedom of TO with the precise boundary representation of SO. Using gradient based optimization, the objective is to design structures in frictionless contact, including the shape of the contacting surfaces. SO is performed on each contacting structure which defines
A platoon consists of a string of vehicles traveling close together. Such tight formation allows for increased road throughput and reduced fuel consumption due to decreased air resistance. Furthermore, sensors and control algorithms can be used to provide a high level of automation. In this context, safety - in terms of no rear-end collisions - is a key property that needs to be assured. We invest
This one-day workshop will explore fabulations in design research. Bringing together design researchers and practitioners in hands-on exploration and critical dialogue, we will explore emerging practices and potentials of using fabulations in futures-oriented and exploratory practice-based design research. Drawing on fabulations’ relations with feminist technoscience and more-than-human concerns,
Tourism is consistently affected by a change. Whether it be economic, social, and cultural, or whether it be technological and environmental, which are the focus of much contemporary tourism scholarship. Furthermore, change occurs at different scales and is uneven over space and time. Therefore, while all change is experienced locally, global overviews such as that provided in this book can only p
The aim of the project MASTER (MAnaging Speeds of Traffic on European Roads) was to produce information that can be cited in the preparation of national and EU decisions concerning speed management and speed control equipment standards. For this purpose, the project looked for answers to three key questions: 1)What are acceptable ranges of speeds? 2)What are the key factors influencing drivers’ ch
Popular Abstract in Swedish Det sägs att ögonen är själens spegel och att man genom att titta på någons ögon kan säga något om personens sinnesstämning och hur personen mår. Forskning kring ögonrörelser har visat att man genom att mäta ögats rörelser kan tolka hur den visuella informationen som vi tar in genom ögonen har behandlats. Eftersom det är hjärnan som styr muskulaturen runt ögat som i sinThis doctoral thesis has signal processing of eye-tracking data as its main theme. An eye-tracker is a tool used for estimation of the point where one is looking. Automatic algorithms for classification of different types of eye movements, so called events, form the basis for relating the eye-tracking data to cognitive processes during, e.g., reading a text or watching a movie. The problems with t
Teacher education for upper secondary school in Sweden is mainly university-based but with parts of the studies as school-based courses. To tackle the main obstacles to pre-service teachers’ placements, and to strengthen collaboration regarding quality and collaborative research, a new national policy is being implemented, which changes the prerequisites for collaboration between schools and unive
This book aims to provide practical aspects of, and an introduction to, the applications of various technological advancement tools, such as AI, machine learning to design, big data, cloud computing, and IoT, to model, characterize, optimize, forecast, and do performance prediction of renewable energy exploitation. It further discusses new avenues for energy sources such as hydrogen energy generat
Background: von Willebrand disease (VWD) type 1 is a congenital bleeding disorder caused by genetic defects in the von Willebrand factor (VWF) gene and characterized by a reduction of structurally normal VWF. The diagnosis of type 1 VWD is difficult because of clinical and laboratory variability. Furthermore, inconsistency of linkage between type 1 VWD and the VWF locus has been reported. Objectiv
We consider construction and realization aspects of encoders and decoders for braided block codes (BBCs), which are a powerful class of iteratively decodable codes. An efficient encoder is proposed as well as a pipeline decoder realization. Also, upper and lower bounds on the free distance of BBCs are derived.
In this paper, we investigate channel estimation and signal detection for UWB communications. We first investigate channel estimation for UWB systems and then develop a minimum mean-square-error (MMSE) Rake receiver with joint timing and MMSE equalization. The key property of the estimator is that it uses sampling at UWB symbol rate (200Msamples/s), while estimating all relevant channel parameters
