Assessment of some turbulence models for slot jet impinging on flat and concave surfaces

A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre

Close approximations of minimum rectangular coverings

We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe

SC-LDPC Codes over the Block-Fading Channel: Robustness to a Synchronisation Offset

Spatially-Coupled LDPC (SC-LDPC) codes have been recently shown to be very efficient for transmissions over nonergodic channels, in particular over block-fading channels [1]. In fact, it is possible to design a SC-LDPC code with any given code diversity [2]. In this work, we investigate the performance of SC-LDPC codes over block-fading channels, assuming a mismatch (or offset) between the first b

Att formulera skriftliga betygskriterier : bedömarkompetens och att sätta praxis på pränt

Betygsättande lärare utvecklar ofta med tiden en stor kunskap om betygskriterier, i så motto att de får en god känsla för vad i en studentprestation som värderas, bedöms och betygsätts – den så viktiga bedömarkompetensen. Ibland formuleras denna kunskap medvetet och explicit, inför läraren själv, liksom inför berörda studenter och kollegor. Andra gånger stannar den som mer tyst kunskap hos läraren

Rehabillitering och välfärdspolitik

Rehabilitation of the long-term sick and individuals with a functional incapacity has recently become a burning political dilemma. It is not only a question of the crisis of the welfare state expressed in higher cost for sick absences and early disability pensions, but also an experienced failure of the welfare state to guarantee participation and social rights. The authors of the book discuss fun

Lay People and Perceptions of Global Risk

The urgent need to be able to make detailed, exact and systematic comparisons which are possible to use in making general statements required not only the development of a methodology, but also methods standardised enough to assure statistical exactness. To achieve a base for detailed comparisons it was essential to combine the information from historical documents and observers´ reports with data

Europadomstolen som prejudikatinstans

Artikeln behandlar i vilken omfattning domar från Europadomstolen för de mänskliga rättigheterna i Strasbourg skall tillmätas prejudikatvärde i framförallt svensk rättstillämpning.

Design and prototyping a torus machine with a rotocast core

A torus machine is considered to be an advantageous machine configuration that is impossible to produce using traditional laminated core technology. This paper presents a torous machine with the stator winding moulded into a composite core, using the RotoCast technology. The goal of the design and the prototyping is to study the advantages when dealing with a soft magnetic mouldable composite mate

Kvotering skapar inga nya jobb

Under april månad i år (1995) var den öppna arbetslösheten bland utomnordiska invandrare 28 procent, medan motsvarande siffra bland svenskar var sju procent. Dessa relativa tal avspeglar invandrarnas respektive svenskarnas svårigheter att anskaffa sysselsättning på arbessmarknaden.

Extended STAPL as SJTAG Engine

Integrated Circuits (ICs) and multi-board systems are becoming increasingly complex to test. A key to successful testing is effective standards. Currently, at micro level the Internal JTAG (IJTAG) focuses on the development of a standard for embedded on-chip instruments while at macro level the System JTAG (SJTAG) works on defining a standard for system level test management; mainly connecting the
