In many application domains, critical systems must comply with safety standards. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system's lifecycle, creating a need for impact analysis to guarantee that system safety and compliance are not jeopardised. Although extensive resear
Diffusion tensor imaging (DTI) is the method of choice for non-invasive investigations of the structure of human brain white matter (WM). The results are conventionally reported as maps of the fractional anisotropy (FA), which is a parameter related to microstructural features such as axon density, diameter, and myelination. The interpretation of FA in terms of microstructure becomes ambiguous whe
The win-win opportunities connected to green growth are appealing to academics and policy makers alike, but empirical evaluations about the effectiveness of green growth policies are still scattered. Taking South Korea as case study, which set up a highly ambitious green growth program in 2009, our research casts light on the extent to which the Korean Green Growth Strategy has been effective in d
Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne
Today risk analyses are commonly used by authorities at national, regional and municipal levels in their work to prevent and prepare for crises. The analyses provide information about types of incidents that can occur and the potential consequences of these events. In Sweden and Norway it is mandatory for local authorities to conduct risk and vulnerability analyses and use them as an input in thei
According to direct perception theory (DPT) people understand each other’s minds by way of perceiving each other’s behavioral engagements in the world. I argue that DPT admits of two interpretations. One interpretation is found in Searle’s social ontology. The other interpretation departs from an enactivist account of social cognition. Both can be employed to make sense of what it is to perceive o
Some extraordinary people have dedicated their lives to making art pieces out of long dead organisms. One of them is Esben Horn, founder of model shop 10 Tons Studios on the outskirts of Copenhagen, Denmark. A bona fide 'master of puppets', he makes jaw-dropping replicas for museums around the world, with the utmost respect for science and organismal anatomy. Recently, our joint efforts resulted i
In this paper we demonstrate a method for novelty detection of foreign objects in food products using grating-based multimodal X-ray imaging. With this imaging technique three modalities are available with pixel correspondence, enhancing organic materials such as wood chips, insects and soft plastics not detectable by conventional X-ray absorption radiography. We conduct experiments, where several
The use of vectoring for crosstalk cancellation in the new ITU-T G.fast standard for next generation DSL systems becomes essential for efficient utilization of the extended bandwidth (up to 200 MHz). In VDSL2 (up to 30 MHz), a zero-forcing-based linear precoder is used in downstream which approaches single-line performance. However, at high frequencies, the linear precoder may amplify the signal p
The Environmental Effects Assessment Panel (EEAP) is one of three Panels that regularly informs the Parties (countries) to the Montreal Protocol on the effects of ozone depletion and the consequences of climate change interactions with respect to human health, animals, plants, biogeochemistry, air quality, and materials. The Panels provide a detailed assessment report every four years. The most re
This paper presents a new approach for the evaluation of User Experience (UX) aspects applied to virtual museums (VM) - VMUXE. A wide percentage of projects and applications for VMs are often "born and buried" in digital labs, without having been experimented and monitored with people. These "prototypes" are the result of experts, technicians, curators, combined together to give birth for multidis
The hypothesis has been tested that evolution has resulted in lower thermal emissivity of eggs of birds breeding openly in cold climates than of eggs of birds that nest under protective covering or in warmer climates. Directional thermal emissivity has been estimated from directional–hemispherical reflectance spectra. Due to several methodological difficulties the absolute emissivity is not accura
Background: Despite the compelling scientific evidence on the superiority of stroke unit care, far from all acute stroke patients have access to stroke unit care. In congruence with what has been observed when other new methods are introduced in health care, we hypothesized that there has been an inequality in the buildup phase of stroke units but that the gradients between patient groups have dec
