Being able to orient in the vicinity of the home and independently go shopping or visiting a friend can become increasingly difficult when a person suffers from memory decline. The adaption of traditional navigation apps based on satellite positioning could provide an aid, but there are several questions to investigate related to the design and function of such an app. These questions include how

Popular Abstract in Swedish De optiska egenskaperna i våra sjöar och vattendrag förändras kontinuerligt. Näringsrika sjöar blir grumliga genom algblomningar och erosion gör vattnet grumligt av lerpartiklar. De senaste årtiondena vattnet också blivit brunare genom att mer humusämnen läcker från omkringliggande mark. Både grumligt och humöst brunt vatten försämrar fiskens siktförhållande, men det skVisual conditions are changing in several different ways. Some lakes are getting turbid due to eutrophication or erosion while others are getting browner due to brownification. These two types of visual degradation results in completely different optical properties of lakes. Turbid water scatter light which degrades image quality severely while brown coloured humic water mainly absorb light making

The aim of this paper is to discuss the implications a complexity perspective may have on the management of logistics. The CLM definition of logistics management is used as a base to address the implications a complexity perspective has on the logistics discipline. A framework is developed to assess the logistics complexity based on significant properties (structure, dynamics and adaptation) on th

Om hur datorbaserade objekt möter konstvärlden och hur de möjligen kan tas upp som konstobjekt.

This chapter discusses the term solidarity in relation to knowledge, and the existing tension between a vital women’s movement on the one hand, and a feminist academic theory on the other. The raise of a highly capitalist and neoliberal notion of feminism, a sort of “free market feminism” is restricting and limiting the space for solidarity in feminist politics and theory. Jodi Dean’s term reflexi

Popular Abstract in Swedish Bakgrund: Öroninflammation är vanligt förekommande i barnaåren. De flesta barn har haft minst en episod med akut varig öroninflammation (AOM) och/eller en period med vätska i mellanörat (SOM) före skolstart. De flesta får enstaka episoder, frekvensen av AOM avtar i 2-års åldern och frekvensen av SOM avtar före skolstart. Efter en AOM episod är det vanligt att man under Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. Subjects and methods: Out of a birth cohort followed to the age of 3 years, 12 child

In this paper it is shown how a convolutional code can be used either to detect errors or to correct erasures. The erasure correction is related to the error detection. Using the active burst distance lower bounds on the error and erasure correction as well as error detection are obtained for convolutional codes.

The text discusses the phenomenon of modern rune carvers within the Nordic countries. The article illuminates the purposes and different meanings connected to the act of rune carving in our time. It is concluded that the shaping of identity in close relation to visions of past times is an important part of the rune carving activities of today.

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

Polarization vision is the ability of animals to detect the oscillation plane of the electric field vector of light (E-vector) and use it for behavioral responses. This ability is widespread across animal taxa but is particularly prominent within invertebrates, especially arthropods. Polarized light can be either used implicitly for enhancing image contrast and for adding another dimension to the

The aim of this pilot study was to ergonomically evaluate the effect of the location of the scales in a supermarket checkout system. A location of the scales to the left of the cashier was compared with a location under the conveyor belt. Two cashiers were videotaped while working with the two scale locations, in both sitting and standing working postures. Analysis of the video tapes was performed
