Tidskriftsartikel (refereegranskat)abstract
- The Beamline for European Materials Engineering Research (BEER) has been recently proposed to be built at the European Spallation Source (ESS). The presented concept of neutron delivery optics for this instrument addresses the problems of bi-spectral beam extraction from a small moderator, optimization of neutron guides profile for long-range neutron transport and focusing at the sample under various constraints. They include free space before and after the guides, a narrow guide section with gaps for choppers, closing of direct line of sight and cost reduction by optimization of the guides cross-section and coating. A system of slits and exchangeable focusing optics is proposed in order to match various wavelength resolution options provided by the pulse shaping and modulation choppers, which permits to efficiently trade resolution for intensity in a wide range. Simulated performance characteristics such as brilliance transfer ratio are complemented by the analysis of the histories of "useful" neutrons obtained by back tracing neutrons hitting the sample, which helps to optimize some of the neutron guide parameters such as supermirror coating.

Accurate nuclear radii and binding energies from a chiral interaction
- 2015
-
Ingår i: Physical Review C - Nuclear Physics. - 2469-9985 .- 2469-9993. ; 91:5
-
Tidskriftsartikel (refereegranskat)abstract
- With the goal of developing predictive ab initio capability for light and medium-mass nuclei, two-nucleon and three-nucleon forces from chiral effective field theory are optimized simultaneously to low-energy nucleon-nucleon scattering data, as well as binding energies and radii of few-nucleon systems and selected isotopes of carbon and oxygen. Coupled-cluster calculations based on this interaction, named NNLOsat, yield accurate binding energies and radii of nuclei up to Ca-40, and are consistent with the empirical saturation point of symmetric nuclear matter. In addition, the low-lying collective J(pi) = 3(-) states in O-16 and 40Ca are described accurately, while spectra for selected p- and sd-shell nuclei are in reasonable agreement with experiment.

Layer approach to ownership in 3D cadastre : a subway case
- 2018
-
Ingår i: 6th International FIG 3D Cadastre Workshop. - Copenhagen : The International Federation of Surveyors, FIG. - 9788792853806 - 9788792853813 ; , s. 111-136

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The paper focuses onapproaches to the registration of real property rights in the case of underground or subway tunnels in different EU countries: Austria, Bulgaria, Czech Republic, Croatia, Greece, Poland, Slovenia, and Sweden. The Authors made analysis of the current way of registration of rights to subway tunnels in the chosen countries, including its effectiveness in ensuring appropriate property rights to construct and exploit tunnels. A special attention was given to limitations related to the lack of the possibility to vertically divide the space, i.e. to divide the space into layers, and to refer the ownership right to the layers. Benefits which might be achieved by the introduction of a 3D real property cadastre were pointed out. The analysis of available data concerning the geometry of subway tunnels in particular countries was presented. The authors tried to answer the question whether the accessible data concerning the geometry of subway tunnels allows to generate a 3D geospatial model of a constructed object, and to specify the space which should be determined as a 3D parcel in the 3D real property cadastre, for the purpose of registering property rights for the object (the tunnel).

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The concepts of three-dimensional (3D) real property have been the subject of increased interest in land use management and research since the late ‘90s. Literature provides various examples of extensive research towards 3D Cadastres as well as those that are already implementing 3D cadastral systems. However, in most countries the legal aspects of 3D real property and its incorporation into 3D cadastral systems have not been so rigorously examined. This paper compares and discusses 3D property concepts in 15 cadastral jurisdictions, based on the authors’ national experience, covering Europe, North and Latin America, Middle East and Australia. Each of the legal system in these cadastral jurisdiction are based on different origins of Civil Law, including German, Napoleonic and Scandinavian Civil Law, which can prove useful to research in other Civil Law jurisdictions interested in introducing 3D cadastral systems. These jurisdictionsare at different stages of introducing and implementing a 3D cadastral system. This contributes to the detection of the 3D real property concepts that apply as well as deficiencies that prohibit introduction of 3D cadastral systems, while highlighting challenges that may have not yet surfaced in individual jurisdictions. This paper aims to present the different legal concepts regarding 3D real property in the examined countries, focusing on the characteristic features of cadastral objects described as 3D within each country’s legal and cadastral framework. The analysis of the case studies revealed that the countries are on different stages of 3D Cadastral implementation, starting from countries with operational 3D cadastral systems, to others where there is yet no interest in introducing a 3D cadastral system. This paper presents the nature of 3D cadastral objects in each country, as well as differences in the regulatory framework regarding definition, description and registration. The paper continues the legal workshop discussions of the 4th International Workshop on 3D Cadastres in Dubai 2014 by analysing the legal concepts of 3D cadastres in the above-mentioned countries. The outcome is an overview and discussion of existing concepts of 3D property describing their similarities and differences in use, focusing on the legal framework of 3D cadastres. The article concludes by presenting a possible way forward and identifies what further research is needed which can be used to draft national and international research proposals and form legislative amendments towards introduction of national 3D cadastral systems.

- The concepts of three-dimensional (3D) real property have been the subject of increased interest in land use management and research since the late ‘90s while literature provides various examples of extensive research towards 3D Cadastres as well as already implementing 3D cadastral systems. However, in most countries the legal aspects of 3D real property and its incorporation into 3D cadastral systems have not been so rigorously examined. This paper compares and discusses 3D property concepts in six selected countries: Austria, Brazil, Croatia, Greece, Poland and Sweden, based on the authors’ national experience. Each of these countries’ legal system is based on different origins of Civil Law, including German, Napoleonic and Scandinavian Civil Law, which can prove useful to research in other Civil Law jurisdictions interested in introducing 3D cadastral systems. Selected countries are on different stages of introducing and implementing a 3D cadastral system; this may contribute to the detection of the main 3D real property concepts that apply as well as deficiencies and malfunctions that prohibit introduction of 3D cadastral systems, highlighting challenges that may have not yet surfaced. This paper aims to present the different legal concepts regarding 3D real property in the examined countries, focusing on the characteristic features of cadastral objects described as 3D within each country’s legal and cadastral framework. The analysis of the case studies revealed that the countries are on different stages of 3D Cadastre implementation, starting from countries with operational 3D cadastral systems, to others where there is yet no interest in introducing a 3D cadastral system. 3D cadastral objects in each country are presented, as well as differences in the regulatory framework regarding definition, description and registration.

Tidskriftsartikel (refereegranskat)abstract
- Three-dimensional (3D) real property has been the subject of increased research activity during the last decade. This article continues the discussions of the legal framework sessions at the 4th international workshop on 3D cadastres in Dubai 2014 in order to further develop and analyse the legal concepts of 3D real property, and presents an overview of experiences from 3D property use and registration. The outcome is intended to initiate discussions on the legal framework of 3D cadastres and aims at identifying the main topics concerning the legal aspects of 3D property and cadastre.
