The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. It differs from a conventional heat pipe device in design and opera

In recent years, as Internet of Things (IoT) and machine learning technologies have advanced, there has been increasing interest in the study of energy-efficient and flexible architectures for embedded systems. To bridge the performance gap between microprocessors and memory systems, Near-Data Processing (NDP) was introduced. Although some works have implemented NDP, few of them utilize the microp

In recent years, the market for mobile applications has continuously grown in size, and appears to continue to grow. This means greater competition among app developing companies as the users expect applications with high usability and a great user experience. To assess these properties the companies can perform usability evaluations. However, practicing traditional usability evaluation methods ca

Visualization of molecular models is a vital part in modern drug design. Improved visualization methods increases the conceptual understanding and enables faster and better decision making. The introduction of virtual reality goggles such as Oculus Rift has introduced new opportunities for the capabilities of such visualisations. A new interactive visualization tool (MolecularRift), which lets t

Denna rapport redogör för design och utveckling av ett medicintekniskt instrument för diagnos av kronisk obstruktiv lungsjukdom (KOL) eller emfysem. Arbetet utgår ifrån en ny diagnosmetod och ett instrument i form av en funktionell prototyp som används för att testa den nya diagnosmetoden. Med utgångspunkt i den funktionella prototypen har arbetet fokuserats kring att förstå vilka problem och utmThis thesis presents design and development of a medical device for diagnosis of emphysema or COPD by controlled lung deposition of nanoparticles. After purging the lungs with particle free air the subject inhales a controlled aerosol mixture and holds his breath for a determined period of time, before exhaling. The degree of lung disease is calculated by measuring and comparing the concentration

A FT-NIR (Fourier-Transform Near Infrared) model for moisture content has been developed for whole seeds of Swedish rapeseed (Brassica napus) by the conditions given during the harvest of 2014. Compared to Internal standardized (ISO) method 665, the final model showed very small differences in terms of repeatability and measurement uncertainty even though the measurement time was four times faster

Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. It has been applied on a case of flooding in south of Sweden and revised based on the result

By using Axis pan/tilt/zoom cameras it is possible to create a simple, high quality video conference system, without the need for a separate computer to control the system. This can be achieved by connecting the camera to a standard television set and utilize open standards like the HDMI feature Con- sumer Electronics Control (CEC). With CEC it should be possible to control the system using a stan

The Volvo Group has an ambitious plan to efficiencies its construction equipment vehicles with an introduction of a hybrid engine. This Master thesis is based on, as a first approach, to control the energy split in a hybrid construction equipment vehicle (HCEV) with the control strategy Model Predictive Control (MPC). The work is divided into two main parts, where the first one is to create a piec

Humanity is facing one of the greatest challenges ever. Climate change and global warming is a great risk and our consumption and dependency of fossil fuel are important causes of this accelerating issue. My thesis aims to design an entry for the professional debate about what urban areas in a fossil free future might be like. I’m investigating how an urban environment that requires as little tra

Bricklaying is one of the most accident-prone professions in the construction industry, with heavy and non-ergonomic lifting being a leading cause of sick leave and back problems. Increased automation is expected to reduce the number of work-related accidents while simultaneously improving productivity. Existing solutions are often expensive and inflexible. This thesis investigates how a pick- and

This thesis explores the application of machine learning techniques to predict mortality risk using data from the Swedish Adoption/Twin Study of Aging (SATSA). Through the development and evaluation of multiple supervised learning models, including Random Forest and Histogram Gradient Boosting classifiers, the study examines mortality predictors across 10-year and 20-year timeframes. The models ac

This study presents a simulation-based framework for evaluating energy renovation strategies across European building typologies and climate zones. A factorial parametric approach was used to simulate over 800,000 combinations of envelope assemblies, HVAC systems, and shading controls for three archetypes (single-family, multi-family, office) across five European climate zones under both current a

Photonics technologies play a crucial role in driving technological advancements within the agrifood industry, aiming to deliver a sustainable food and agriculture, and offering healthy, nutritious and safe food for all of us. Particularly, optical sensors and imaging systems, together with machine-learning processing and advanced lighting, play a pivotal role in monitoring crop and soil health wi

BACKGROUND: Despite decades of initiatives promoting individual behavior change, obesity rates remain high and continue to rise globally, indicating that what is commonly labelled as “obesity prevention” is not, in practice, preventing obesity. While health promotion strategies and policy interventions have demonstrated improvements in environments, health behaviors, and industry practices, their

Following the successful first Urban Sound Symposium held at Ghent University in 2019, the second edition in 2021 had to face the challenges of the pandemic. The symposium turned this challenge into an opportunity for giving easier access to practitioners and experts from around the globe who are confronted with urban sound in their professional activities. It was organized simultaneously in Ghent
