Europeiska möten med historien : historiekulturella perspektiv på andra världskriget, förintelsen och den kommunistiska terrorn

1990-91 drogs nya gränser i Europa. Inte bara kartan ritades om. Också historien har förändrats när 1900-talets avgörande händelser, andra världskriget, förintelsen och kommunistterrorn, tagits i bruk för att skapa ett nytt Europa. Det är visserligen en process som pågått under hela efterkrigstiden, i den tyska skuldbearbetningen, debatten om det totalitära samhället, det ökade intresset för förin

Receiver Front-Ends in CMOS with Ultra-Low Power Consumption

Popular Abstract in Swedish I avhandlingen presenteras delar till radiomottagare med extremt låg effektförbrukning. Detta behövs då dagens samhälle blir allt mer och mer uppkopplat, och detta gäller inte bara persondatorer och mobiltelefoner. Med den snabba teknikutvecklingen inom radiokommunikation, driven av små och smarta mobiltelefoner, går det nu även att få prylar av alla de slag att tala meHistorically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. They should be able to offer basic connectivity with a power consumption low enough to function extended periods of time on a single battery charge,

Numerical investigations of the acoustics of a coaxial nozzle

The acoustic field generated by two coaxial jets is studied numerically. The turbulent non-isothermal flow is handled by Large Eddy Simulations (LES) and the acoustical perturbations are treated by solving an inhomogeneous wave equation. The acoustical source is obtained from the instantaneous LES flow field. The computed flow and acoustical fields are compared to measured data. Good agreement bet

The thinking in law and politics during 1915 and 1973 is exposed.

Gaining legitimacy in contemporary world

This article investigates the links between environmental and social activities of organisations and organisational legitimacy. The recent overemphasis on the business case for voluntary environmental and socialactivities of organisations is undermining the attention to other drivers such as legitimacy concerns. Previous literature has discussed how the principle of legitimacy may underpin corpora

A unified view of systems

A unified view of systems is suggested which relates to both model theory and relational databases. The approach towards a unified view is here centered around viewing a system as a structure of the form S = < A, R > putting focus on the relational aspects of the system concept. This is motivated by some examples of various systems which are shown to fit into the proposed unification.
