Estimating stellar ages and metallicities from parallaxes and broadband photometry : Successes and shortcomings

A deep understanding of the Milky Way galaxy, its formation and evolution requires observations of huge numbers of stars. Stellar photometry, therefore, provides an economical method to obtain intrinsic stellar parameters. With the addition of distance information - a prospect made real for more than a billion stars with the second Gaia data release - deriving reliable ages from photometry is a po

Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016 : a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults

Background Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods We pooled 2416 popu

Discrete-Time Trials for Tuning without a Model

Given a static plant described by a differentiable input-output function, which is completely unknown, but whose Jacobian takes values in a known polytope in the matrix space, we consider the problem of tuning the output (i.e., driving the output to a desired value), by suitably choosing the input. To this aim, we assume to have at our disposal a discrete sequence of trials only, as it happens, fo

Children's practice of computer-based composition

Today’s children live in a world where music in all its different forms has become a significant factor in their everyday life. This article describes a 2-year empirical study of nine 8-year-old Swedish children creating music with synthesiser and computer software. The aim of the study is to describe and clarify the creative processes of computer-based composition. The tasks given to the children

Techniques for and consequences of using INSPIRE extensions : a case study with Swedish hydrological data

The demand for easily available geographic information is increasing in society. Moreover, knowledge of spatial data infrastructures (SDIs) has increased in many European governmental agencies, in large part because of the implementation of the INSPIRE directive. Many countries, thus, recognise the need to provide more detailed geographic information as network services at the national level. One

Multiple Representation for Geospatial Linked Data

Current techniques for visualising geospatial Linked Data are limited in terms of multiple representation, which has been studied for decades by cartographers and considered as a prerequisite for deriving appropriate geovisualisation applications. In order to alleviate this issue, this paper presents a work in progress, in which the multiple representation geospatial data are released as Linked Da

The need for country masks for future national greenhouse gas flux estimations

The Paris Agreement requests a substantial reduction of greenhouse gas (GHG) emissions. These emissions are currently mainly estimated from bottom-up inventories and process-based models of land and ocean fluxes. Another, complementary approach is based on measurements of the atmospheric GHG concentration in combination with atmospheric inverse modelling to provide the GHG fluxes. For the latter a

Sharing building information from planning to maintenance phases

The sharing of digital information between phases in the planning and building process still have shortcomings. Ourstudy is performed as a test case on a construction project in a municipality and focuses on two aspects of how the sharing of building information could be improved: 1) to get a more process oriented approach to the information flow. Here we will test if the ISO-standard Product Life

Norm Formation from the Inside of a Swedish Court

The overarching aim of this sociology of law study is to explore internal processes at a court to get deeper knowledge of norms within this legal organisation. The point of departure is a specific research interest in studying professional norms on ‘good treatment’ in a local court. Another aim is to study the importance that the internal professional norms have on the external treatment of visitoThe overarching aim of this sociology of law study is to explore internal processes at a court to get deeper knowledge of norms within this legal organisation.

Prediction of summer precipitation in the source region of the Yellow River using sea surface temperature

The source region of the Yellow River contributes about 35% of the total water yield in the Yellow River basin playing an important role in meeting downstream water resources requirements. Thus, it is important to accurately predict the summer precipitation to get better estimation of streamflow for the Yellow River. In this study, the close links between summer precipitation in the source region
