Being autonomous (or being an agent) does not describe an effective process and even if we succeeded in characterizing the conditions for being autonomous it would be of no use. Instead, it is the conditions of acting autonomously that should be of concern and the interest should be directed towards systems in which we can find, and possibly define, such acting processes. It turns out that anticip

This paper presents an evaluation of single input single output (SISO), single input multiple output (SIMO) and multiple input multiple output (MIMO) channel capacities for a dual antenna prototype in proximity of a user. The dual antenna prototype mimics today’s small mobile phone design in size and in comprising internal, compact, multi-band antennas. Four different user cases are evaluated by m

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

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,

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.

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
