The use of longitudinal historical micro-level demographic data for research presents many challenges. The Intermediate Data Structure (IDS) was developed to try to solve some of these challenges by facilitating the storing and sharing of such data. This article proposes an extension to the IDS, which allows the standardization and storage of constructed variables. It also describes how to produce
The effect of reaction temperature, water content, and vanadia content on the sintering of a model vanadia on silica-titania SCR catalysts has been investigated. A comparison is also made to a monolithic vanadia/titania catalyst submitted to conditions simulating at least 500,000 km driving on a diesel truck. The variation of the surface area, the pore structure and the crystallite size of the cat
The performance of an iris recognition system depends greatly on how well the iris segmentation part of the system performs its task. The performance of an iris segmenta- tion algorithm can be evaluated using different criteria and methods. Some of the methods evaluate the performance of the segmentation algorithm based on the performance of the whole iris recognition system. Other methods evaluat
When adapting environments for the physically disabled, it is important to encourage and activate not only the person concerned, but also other people involved or affected. A computer aided planning tool has been developed to support the participation of all persons involved, as well as supporting the planner’s (e.g. an occupational therapist) design of the environment. The prototype development a
In this paper we prove threshold saturation for spatially coupled turbo codes (SC-TCs) and braided convolutional codes (BCCs) over the binary erasure channel. We introduce a compact graph representation for the ensembles of SC-TC and BCC codes which simplifies their description and the analysis of the message passing decoding. We demonstrate that by few assumptions in the ensembles of these codes,
To fulfill increasing requirements within the manufacturing sector, highly flexible and adaptable automation systems are needed. It is desirable to have one integrated approach that stretches from the process planning phase, through the implementation phase and all the way to the phase for execution of the process control logics. One promising approach is to use the concepts of service-oriented ar
Theoretical considerations of eye design allow us to find routes along which the optical structures of eyes may have evolved. If selection constantly favours an increase in the amount of detectable spatial information, a light-sensitive patch will gradually turn into a focused lens eye through continuous small improvements of design. An upper limit for the number of generations required for the co
The monotone rearrrangement algorithm was introduced by Hardy, Littlewood and Po ́lya as a sorting device for functions. As- suming that x is a monotone function and that an estimate xn of x is given, consider the monotone rearrangement xˆn of xn. This new estimator is shown to be uniformly consistent. Under suitable as- sumptions, pointwise limit distribution results for xˆn are obtained. The fra
With today’s rapid changes in socio-economy and technology, knowledge and learning are critical issues for private and civil service organizations. The needs for competence development range from short informal courses (without ECTS credits) to formal courses at university level (with ECTS credits). This article describes objectives and results of a Leonardo project, eGIS+ that developed and imple
It is often suggested that the emittance coupling of a storage ring should be adjusted to the so-called diffraction limit corresponding to the shortest wavelength of interest. For 1 Å radiation this leads to a typical requirement of 8 pm rad vertical emittance. In ultralow-emittance storage rings like the MAX IV 3 GeV storage ring this corresponds to a comparably large setting of the emittance cou
The last ten years have seen a sharp increase in externally supported capacity development initiatives for disaster risk management. However, not all of them have generated sustainable results. The purpose of this paper is to scrutinize the current focus on training as the main tool for capacity development in the context of disaster risk management, and to argue for the necessity to address capac
Popular Abstract in Swedish Etanol som produceras från förnyelsebara råvaror kan ersätta fossila bränslen som t.ex. bensin och diesel. Denna avhandling behandlar den enzymatiska processen för etanolproduktion från barrträd. Baserat på datorprogrammen Aspen Plus och Icarus Process Evaluator har ett verktyg för tekniska och ekonomiska beräkningar tagits fram i vilket hela processen, från trä till etEthanol produced from renewable resources can be used to replace fossil fuels such as gasoline and diesel. This thesis deals with the development of the enzymatic process used for ethanol production from softwood. A techno-economic tool, based on Aspen Plus and Icarus Process Evaluator, was developed in which the whole process, from raw material to ethanol, was studied and critical process paramet
