This study examines whether machine learning (ML) models can forecast daily Bitcoin price directions and generate statistically significant alpha in trading strategies. Employing a dual-model approach, we utilize a Random Forest (RF) classifier, leveraging its non-linear strengths and a LASSO-penalized logistic regression as a linear benchmark. Both models are trained on a comprehensive dataset o

Growing environmental concerns have brought a focus to the impact of building materials. In response, biobased alternatives are being explored for their potential to reduce embodied carbon, support circularity, as well as improve indoor environmental quality. This is particularly important in Scandinavia, where moisture-related issues are common, there is a growing need for locally available mater

Although remote video communications are prevalent, they lack some natural aspects of usual human interactions. To an extent, these aspects can be reintroduced by immersive technologies and human digital representations, the avatars. A commonly occurring challenge faced by such Extended Reality applications is communication between dissimilar spaces, i.e. spaces with different layouts. In such la
