A new approach to the problem of estimating parameter in material models is presented. The approach is based on a state space representation of the constitutive equations and one step predictions. The differences between one-step predictions and the corresponding measurements are used to design generic one-step prediction error estimators, and in particular, the maximum likelihood method is presen

Peripheral areas with declining traditional industries often see tourism as a solution for multiple macroeconomic problems. In these regions particularly small and medium-sized enterprises constitute the backbone of the tourism product, and thus are regarded as key players in economic restructuration and rejuvenation (Cooper and Buhalis 1992). At the same time, non-price factors have come into foc

About narration and memory in Lars Gustafsson’s novel "Windy berättar" (1999).

Study of British director Michael Winterbottoms adaptation of Laurence Sternes novel Tristram Shandy.

Risk management is an important process and risk identification is an important part of this process, especially in development of medical software. This paper presents an experiment where physicians, developers and software developers for medical devices are asked to identify risk in a given scenario describing the procurement of a patient monitoring system. It is concluded that multiple roles an

Popular Abstract in Swedish Olika aspekter angående transportmekanismen för aminosyran L-dopa in i så kallade Langerhans celler (LC) i människans överhud och överhudens energimetabolism är undersökta och karaktäriserade. LC har flera olika funktioner i huden, och är en av de mest perifera delarna i vårt immunsystem mot omvärlden. Cellerna vandrar ut i huden från blodkärlssystemet. Cellerna kan äveBased on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. The Falck/Hillarp histofluorescence met

The self-pressurization phenomenon is studied numerically with the Volume of Fluid (VOF) method in a cryogenic fluid tank. Heat and mass transfer modelling is used for the phase change calculation at the interface. Transient simulations of the vaporization and pressure rise in a cylindrical liquid hydrogen tank are performed. The computations are carried out by using the CFD software package, Ansy

This is a study on the potential of NOAA satellite data for operational early warning and food security monitoring at a national level. Ethiopian NOAA NDVI 15-day composites (1981-1985) are analysed and compared to precipitation data including time series records from more than 200 stations. Anomaly analyses are introduced and the regional distribution of the 1984 drought is clearly identified. A

The interaction among various stakeholder organizations in modern crisis response is very similar to negotiation where each organization has its own goal in addition to a common goal. Decision makers in stakeholder organizations most often have to settle for win-win situations to attain higher joint benefit. In such cases willingness to contribute in joint tasks becomes a prerequisite. In our pres

Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface, ie the radome, is analyzed. The transformation is based on the surface integral representation that relates the equivalent currents to the

Popular Abstract in Swedish Proteiner är en av kroppens viktigaste beståndsdelar. Proteiner bygger upp stabila nätverk för att cellerna ska ha sin rätta form, de transporterar in vatten, salt och andra molekyler in i cellerna så att vi kan ta upp näring och de katalyserar kemiska reaktioner. Proteiner är uppbyggda av aminosyror som binds ihop till en kedja och som sedan veckar ihop sig så att protSeveral neurodegenerative diseases are caused by peptides or proteins forming amyloid fibrils such as the Aβ peptide involved in Alzheimer’s disease and the huntingtin exon-1 with a prolonged polyglutamine (polyQ) stretch involved in Huntington’s disease. The ability to form amyloid fibrils is an intrinsic feature in all proteins. The fibrils are built up of monomers to form elongated structures w

In this paper two simplified transform based estimators for MIMO OFDM systems using the DFT and an SVD based transform are compared over a tapped delay line channel model. In the resulting symbol error rate plots, it is seen that the DFT based estimator experiences an error floor caused by the mismatch between the discrete time model and a continuous time reality. This error floor becomes a proble
