There is limited information about the behavior and movement of people in case of fire evacuation in smoke-filled environments, and there is limited guidance on how peoples’ walking speed in smoke can and should be represented in the fire safety design process. In this report, a literature review within this area, and a subsequent recommendation on how to represent walking speed in both smoke-free
The oeuvre of the recently deceased Chilean writer Pedro Lemebel (1952–2014) can be described as an expression for systematically persecuted, repressed, censored minoritarian voices, both during the Chile of the dictatorship, that is during the 1970s and 1980s, as well as afterwards, in democratic Chile, that is from the 1990s onwards. These voices build discourses where gender, class or ethnic id
Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of parent phase and crystal orientation into account in proper way, as being illustrated by the simulation of austenite to ferrite transformation in lo
Small ligaments connecting the fracture surfaces just behind a moving crack front are assumed to exist under certain conditions. The ligaments are rapidly torn as the crack advances. Inelastic straining of such ligaments influences the energy balance in the fracture process. The rapid tearing of a single ligament is studied both numerically and experimentally. An elastic visco-plastic material mod
Abstract: Reports and studies repeatedly indicate that foreign languages other than English are facing major challengesin European educational systems (European Commission, 2012). In Sweden, pupils’ motivation to learn a secondforeign language (SFL) is reported to be low while motivation to learn English is high (Eurobarometer 2012, Tholin& Lindqvist 2009). While there are plenty of studies st
The first online segmentation multi-target tracking algorithm with reported real-time speeds is presented. Based on the popular and fast bounding box based tracker SORT, our method called SORTS is able to utilize segmentations for tracking while keeping the real-time speeds. To handle occlusions, which neither SORT nor SORTS do, we also present SORTS+RReID, an optional extension which uses ReID ve
Information flows can affect people’s apprehension of the pandemic and related behaviors. The aim is to explore how people access and assess COVID-19 information and whether sociodemographic factors are associated with these processes. Quantitative data from 928 persons from 29 countries who participated in an international web-based survey was analyzed with descriptive and analytic statistics. T
In a method and a mobile communications receiver for performing signal measurements, signal measurement data is received from at least one base station during at least part of a measurement period. Each measurement period comprises a number of non-equidistant snapshot measurement windows during which the receiver receives signal measurement data. At least one average signal strength value of the s
SynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a ster

Risk assessment is a useful tool to inform decision-making when it comes to ensuring the continuous operation of critical societal functions. It can be used on many levels within an organization or on multiple societal levels. One way to conduct risk assessments on a higher system level, such as on national level, is to aggregate risk information from lower-level assessments, e.g. from the regiona
Age is a commonly used criterion in social work, whether for entry and exit or for decisions about the appropriate measures for clients. This study introduces the concept of age logics in social work and investigates the use of age in ‘wet’ eldercare facilities. Wet eldercare facilities are harm reduction arrangements open to people over the age of 50 with long-term substance misuse. No treatment
The closed-cycle hydrogen-fueled argon power cycle is a zero emissions concept that combines a carbon-free fuel with argon as a diluent replacement for nitrogen. The lack of nitrogen in the argon power cycle results in zero NOx emissions on an internal combustion engine platform. There is also massive efficiency improvement because argon is monatomic and has a very high ratio of specific heats. Ho
The combination of symmetric positive definite (SPD) covariance matrices and affine-invariant Riemannian (AIR) geometry is a state-of-the-art approach for decoding motor imagery (MI) electroencephalography (EEG) data. However, standard covariance matrices capture only spatial correlations while discarding temporal dynamics like phase relationships and correlations over time. Capturing such tempora
Thirty years on, gender mainstreaming is still a dominant strategy for working with gender equality, even though its effectiveness is debated. This is also the case in Sweden. This study focuses on how organizations in public administration, particularly municipalities and regions, are introduced to and approach gender mainstreaming. It aims to contribute with in-depth knowledge of how organizatio
In Singapore, children’s education is typically presented as “an overriding and all-consuming concern,” fueled by extreme competition for grades and school admissions (Waters 2015: 290). However, parents' desire for academic excellence as a route to better lives is not as straightforward as it may seem. Drawing on ethnographic fieldwork with Singaporean families, this paper explores parents' gende
After having received criticism during previous inter-governmental conferences the European union decided to arrange a convention on the future of europe during 2002 in order to draft a European constitution. This was done to foremost to improve the transparency, participation and decision-making in the preparatory phase of inter-governmental conferences. At first, it received little attention, bu
