Two different rainfall-runoff models are applied to river basins in northern Sweden and Finland to study the effect of changed climate on peak flows. Hypothetical meteorological data series are constructed by increasing observed values by given amounts and fractions. In a Swedish moderately large basin snowmelt and daily precipitation were considered, and in two small Finnish basins, hourly precip

Avsikten med denna rapport är att presentera delresultat från forskningsprojektet "Dynamisk Beskrivning med Datorstödd Bild" (DBDB). I projektet arbetar psykologer, arkitekter och arbetsmiljötekniker med att utveckla och utvärdera dels tredimensionella rörliga bilder (verklighetstrogen animering) och simulering på dator, dels en beteendevetenskaplig metod och samarbetsform. Syftet är att skapa för

An iterative receiver for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) wireless systems is presented and tested on channel measurements from a real indoor scenario. The receiver jointly performs channel estimation and multiuser detection, with soft information iteratively provided by the singleuser decoders. Results for the performance are presented in te

Planning is compared with evolution. Evolution is the most powerful - and cruel, from a human point of view. Evolution does not plan, while planning man tries to avoid the cruel tests for fitness by founding his activities on a growing knowledge of evolution. Evolving man is studied in terms of his linguistic abilities which extend in for example technological domains. A linguistic complementarity

Popular Abstract in Swedish För att tillverka en pappersbaserad förpackning är det viktigt att materialet är tillräckligt hållfast. Förpackningsmaterial består ofta av kartong, aluminium och polymerfilmer där kartong utgör den största delen av förpackningen och bidrar mest till styvheten. Det säljs årligen mer än hundra miljarder förpackningar i världen och om kostnaden samt materi- alåtgång för aContinuum based elasto-plastic-damage models for paperboard have been established in this work. The thesis begins with an introductory section that describes the mechanical properties of paperboard and some of the converting processes during forming of a package. A short review of modeling concepts that have been applied to paperboard is presented and then some key aspects and assumptions develope

In the post 9/11 era the effort to strengthen democracy in weak and fragile states has become a common undertaking of prominent international actors in their foreign policy agendas. In much of the academic and policy discourse democracy assistance has been framed as a solution to political instability and under-development in troubled states. With the case of the Middle East and North Africa regio

Executive summary The general aim of this report is to establish the state of the art of Impact Assessment (IA) in the EC and some selected European countries, while comparing the formal political advances with impact assessment work in practice. Two of the selected countries belong to the group that is identified as forerunners in IA development, Sweden and UK. France is an example of a country w

Regeln för subjekt-verbkongruens i engelskan anses ofta vara enkel, både att förstå och förklara. Ändå gör inlärare överraskande ofta fel, något som lärare som undervisar i engelska i skolan och på högskolenivå märker och ofta påpekar. Det är därför intressant att undersöka om källan till inlärarnas bristande förmåga är 1) ofullständig kunskap om regeln för subjekt-verbkongruens (d.v.s. explicit k

The time evolution of incipient necks is studied numerically for planar and axisymmetric bars subject to high-rate extension. The material is taken to be elastic-plastic and fully non-linear dynamic effects are accounted for. Two main types of growth of necks are observed; stable neck-development that results in fully developed necks and unstable neck-development that leads to weakly developed nec
