Ribbed channel flows are encountered in numerous engineering applications to promote turbulence and enhance heat transfer in various cooling passages, e.g., in turbine blades and at combustor walls. Numerical simulations have become an increasingly useful tool for providing insights into complex turbulence and flow separation, which are critical to the design and optimization of such channels. In

In this paper, we describe the extraction of all the location entries from a prominent Swedish encyclopedia from the early 20th century, the Nordisk Familjebok 'Nordic Family Book.' We focused on the second edition called Uggleupplagan, which comprises 38 volumes and over 182,000 articles. This makes it one of the most extensive Swedish encyclopedias. Using a classifier, we first determined the ca

This paper focuses on constructing models that predict a Value at Risk (VaR) estimation for financial portfolios using hierarchical clustering and copulas. Traditional VaR models often assume linear dependencies and normal distributions, which can be poor assumptions for financial data - especially during extreme market events. This paper introduces a non-linear modeling approach using copulas to

Several studies have shown the benefits for teachers and students in using Sound Field Amplification Systems (SFA). This study evaluates the effects of SFAs on reducing vocal strain in daycare staff and enhancing children's concentration in noisy environments. The study's novelty lies in exploring SFA use in the complex environments of daycare centers. Utilizing a mixed-methods approach, structure

In this paper, we revisit the problem of estimating the relative pose from a sparse set of point-correspondences. For each point-correspondence we also estimate the relative depth, i.e. the relative distance to the scene point in the two images. This yields an additional constraint, allowing us to use fewer matches in RANSAC to generate the pose candidates. In the paper we propose two novel minima

Research connecting text and images has recently seen several breakthroughs, with models like CLIP, DALL•E 2, and Stable Diffusion. However, the connection between text and other visual modalities, such as lidar data, has received less attention, prohibited by the lack of text-lidar datasets. In this work, we propose LidarCLIP, a mapping from automotive point clouds to a pre-existing CLIP embeddin

Semiconductor technology constantly advances, enabling integrated circuits (ICs) with increasingly numerous, faster, and smaller transistors. While this progress offers many benefits, it also presents new challenges, such as tighter margins, wear-outs, and process variations. To effectively tackle these challenges, the conventional approach of using external test instruments during manufacturing t

Mobile stroke units (MSUs), which are specialized ambulances equipped with a brain imaging device and staffed with trained healthcare personnel, have the potential to provide rapid on-site diagnosis and treatment for stroke patients. However, efficient access to prehospital stroke care requires optimizing the placement of MSUs. The MSU allocation problem has been previously solved using a traditio

Recent years have brought new directionality to university’s work with innovation – increasing the focus on addressing societal challenges and contributing to much broader frames for impact. Working with complex challenges, where no one actor can do everything by themselves, requires collaboration across actor groups (private sector, academia, public sector, civil society), industrial sectors, dis

Electric road systems (ERSs) present a transformative advancement in transportation electrification, offering continuous charging capabilities for electric vehicles (EVs) during travel. This innovation has the potential to significantly mitigate range anxiety by enabling in-motion charging, thereby enhancing the overall efficiency of electric mobility, and reducing the frequency of charging stops

Three-dimensional Large Eddy Simulations (LES) are conducted on a non-premixed hydrogen-air annular rotating detonation combustor (RDC). A 22-step finite-rate chemistry reaction mechanism and a flow solver previously developed for high-speed reacting flow are used to perform the LES’. The selected case is an RDC designed by the US Air Force Research Laboratory and has been studied experimentally a

Alternative jet fuels can be radically different from conventional fuels in composition, and the consequences of these differences are a subject of ongoing research. Numerical combustion simulations are vital to this research, and require chemical reaction mechanisms that accurately capture the chemical pathways of combustion. For turbulent combustion, these mechanisms must also be compact and eff
