In this paper simulations of a 130-nm CMOS 24-GHz automotive radar transmitter with digital beam steering is presented. The beam steering is performed by multiple PAs connected to separate antenna elements. The output phases of the PAs are individually controllable through 360◦ by binary weighting of quadrature phases. The circuit contains 18 PAs, each delivering 0 dBm to the antenna, resulting in

In making capacity estimates and cost calculations in the manufacturing industry, many products and production systems are often involved, making the data in their totality difficult to grasp. Introducing the concept of the characteristic part, which is a fabricated part seen as representative of all parts produced in terms of demand, setup time, cycle time, average batch size and total number of

I undersökningen analyseras ett stort antal uppgifter om hur hushåll använder energi i hemmet inom olika funktionsområden samt hur fastighetsägare ser på hushållen som energikunder och hur hushållen själva ser på energitjänstföretagen och sina möjligheter att spara energi. Ett viktigt syfte var att kartlägga i vilken mån allmänt rekommenderade beteenden för att spara energi hemma förekommer blan

There has recently been an increased interest among academic scholars on the importance of elections per se as promoters for democratic change in semi-democratic contexts. This study positions itself somewhat on the side of this debate asking; when do elections in electoral authoritarian regimes result in democratic consequences? Recognising that elections can be as well a tool for democratic empo

The café is a social meeting place. An as yet un-moulded aspect of social life is boundaries – how meetings rest on boundaries between participants that their intercourse brings forth. The aim of this dissertation is to study the café as a sociological and social–psychological phenomenon and at the same time contribute to forming the social–psychological aspect of boundaries. The study also contri

En uppsats som diskuterar problem vid översättning av två kapitel ur en tyskspråkig bok om ugglor. Diskussionen innefattar dels hanteringen av ett tyskt ord med särskilda konnotationer och som saknar direkt motsvarighet i svenskan, dels tänkbara strategier vid översättning av ljudhärmande ord, d v s försök att i skrift beskriva ugglornas olika läten.

New organizations emerge in times of social change. Their survival depends on their ability to mobilize resources in an environment defined by an old order, and thus they must adapt to it. Since new organizations learn how to adapt by mimicking already succesful organizations, their structure tend to become increasingly similar to the structure of those organizations. The thesis tells the story of
