We propose a new dynamic and efficient bounding volume hierarchy for breakable objects undergoing structured and/or unstructured motion. Our object-space method is based on different ways to incrementally update the hierarchy during simulation by exploiting temporal coherence and lazy evaluation techniques. This leads to significant advantages in terms of execution speed. Furthermore, we also show
In connection to a large tunnel project in Sweden a model study of the resolution of resistivity tomography with different electrode arrays has been carried out. Resistivity tomography will be used within the tunnel project for in site measurements in boreholes in front of a TBM and possibly for monitoring the freezing of a weak zone.
Immunization is highly effective in preventing infectious diseases and therefore an indispensable public health measure. Allergic patients deserve access to the same publicly recommended immunizations as non-allergic patients unless risks associated with vaccination outweigh the gains. Whereas the number of reported possible allergic reactions to vaccines is high, confirmed vaccine-triggered aller
The fluorescence emission following inner-shell excitation of molecules has been analyzed in the wavelength region 300 nm≤λfluo≤1000 nm. The main contributions to the experimental spectrum are due to transitions of the parent molecules ionized in the outer valence shells as well as to the radiative decay of excited photofragments, mainly neutral and singly charged atoms. As an example, the dispers
BACKGROUND: Due to the current world situation, Sweden has one of the highest asylum applications within the European Union. Immigrant mothers, specifically those who have immigrated during the last ten years and do not speak the language of the new country, are found to be at particular risk of being effected by postpartum depression.AIM: In this study, we elucidate Swedish Child Health Services
Many environmental strategies relying on a mere improvement of resource productivity and eco-efficiency of processes and products are not able to fully address the environmental impacts induced by increasing consumption. In addition to these strategies, the concept of sustainable consumption calls for changing the levels and patterns of consumption, which require complimentary approaches. However,
Women tend to have lower interest in engineering as compared to men, which previous research has shown is partly explained by gender differences in self-efficacy, social belongingness and communal career goals. Therefore, to attract more women to engineering, effective interventions are needed that target these factors. In this study, we evaluated an industry-designed intervention for high school
Long-distance migrants face numerous challenges during their migration, with the spring migration timing being particularly important, as early arrival at the breeding grounds often enhances breeding success. Both innate and environmental factors influence migration timing in birds, and the earlier arrival of males than females is common among songbirds breeding in temperate zones. The great reed
This paper presents an investigation concerning the introduction of Extreme Programming (XP) in software development organisations. More specifically the concept of using a decision support method known as the Analytical Hierarchy Process (AHP) is evaluated by a group of students and a group of developers and the outcome is compared to experiences from an XP case study. The results provide an indi
Energy security is often analysed from a state centric perspective - sometimes as a sub part of national security. That approach disguise the heterogeneity and importance of different actors. This study analyse actor’s roles and capabilities that affect their own and others energy security strategies. The Swedish road transport sector is used as an example. The study also explores how a transition
