This paper describes preliminary results from the test-retest of the NAME 1.0. Four scales were tested: Mobility-related participation frequency; Mobility ease/difficulty; Mobility dependence; Extent of assistance in mobility. The test was conducted in the five Nordic countries. In all 147 mobility device users took part in the study, mean age 60 years (range 19 - 93). Each participant was intervi

Iterative decoding methods allow efficient decoding of long codes that are composed of smaller component codes. As a result reliable communication can be achieved with low decoding complexity even for rates close to Shannon capacity. This makes iteratively decodable codes a very attractive object of study in modern coding theory. This thesis focuses on different kinds of cycles which appear in th

Three pyralid moths, the Mediterranean flour moth (Ephestia kuehniella), the almond moth (Ephestia cautella) and the Indian meal moth (Plodia interpunctella), infest food products all over the world and cause severe problems in factories, shops and households. For health and environmental reasons chemical control becomes more and more restricted. We here present some promising results offering eff

Förmågan att effektivt utnyttja och kritiskt förhålla sig till olika informationsresurser – ”information literacy” eller informationskompetens – är en central färdighet i det moderna samhället. Det utgör också en allt viktigare del av lärandet i högre utbildning. Syftet med detta paper är tvåfaldigt: 1) att problematisera relationen mellan informationskompetens som en generell färdighet och mer sp

Current-mode control can be used to control switched DC-DC power converters. This paper compares two continuous-time models for current-mode control that are made to be accurate up to half the switching frequency. The two models are the ones presented by Ridley and Tan. The closed loop frequency responses predicted by these two models are compared with results obtained from simulations of a buck c

Riter och ritual är mångsidiga fenomen vilket gör att studiet av formaliserade handlingar återfinns inom flera ämnesdiscipliner. I Den rituella människan – flervetenskapliga perspektiv visar forskare inom arkeologi, etnologi, psykologi, teatervetenskap, religionshistoria och teologi hur de har funderat över den rituella praktiken. Varför använder människan sig av riter, hur kan rit och ritual stud

Web sites are exposed to high rates of incoming requests. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. An admission control mechanism rejects some requests whenever the arriving traffic is too high and thereby maintains an acceptable load in the system. This paper presents how admission control mechanisms can be designe

Governmental organisations are becoming more critically dependant on IT systems such as communication systems or patient data systems, both for their everyday tasks and their role in crisis relief activities. Therefore it is important for the organisation to analyse the reliability of these systems as part of the organisation’s risk and vulnerability analysis process. This paper presents a practic
