Two different frequency doubling power amplifier topologies have been compared, one with differential input and one with single-ended, both with single-ended output at 60 GHz. The frequency doubling capability is valuable from at least two perspectives, 1) the high frequency signal is on the chip as little as possible 2) the voltage controlled oscillator and power amplifier are at different freque

Popular Abstract in Swedish Denna avhandling kan delas in i två delar. Den första delen behandlar en analys av en vanlig parameter estimations algoritm - Rekursiv Minska Kvadrat (RMK) algoritmen. Denna algoritm används ofta inom tekniska tillämpningar när man vill estimera modeller i realtid. T.ex. kan RMK användas för att finna modeller på hur framtida elförbrukning i Malmö (eller någon annan staThis thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor. The exact statistical properties for the RLS-estimator with forgetting factor ar

Popular Abstract in Swedish I stormaktstidens Sverige utgavs en fornsaga där den mytiske svenske kungen Vilkinus ligger med havsfrun. Under denna tid kunde vanliga människor som påstod sig ha sådana förbindelser dock råka illa ut. År 1630 förhördes pigan Anna Larsdotter, som misstänktes ha fött näckens monstruösa avkomma. ”Trollkarlen” Peder Jönsson avrättades tio år senare för könsumgänge och pakThis dissertation examines conceptions of erotic nature spirits and their association with demonic sexuality in 17th and 18th century Sweden. Its purpose is to reconstruct the various cultural and symbolic meanings which such notions had for the society of the day. Cultural history and the analytical concepts culture(s), liminality and figures of thought provide the general framework of the study.

Public service organizations rely on IT systems to fulfill their missions. IT incidents are more and more frequent and the impacts of IT incidents on the organizations are getting more severe. There is a strong need to manage risks on service related IT systems in public service organizations. Risk management process practiced in software development companies cannot be used in public service orga

A common assumption in motion blur rendering is that the triangle vertices move in straight lines. In this paper, we focus on scenarios where this assumption is no longer valid, such as motion due to fast rotation and other non-linear characteristics. To that end, we present a higher-order representation of vertex motion based on Bézier curves, which allows for more complex motion paths, and we de

Complex problem spaces, such as those addressed by knowledge management or systems analysis projects, call for complex methods of inquiry. A phenomenon in contextual analysis means that there is a need to go beyond consensus and recognized ‘best practice’. As part of a complex method, for contextual analysis, inter-analysis may be conducted, in which individuals explore one another’s perspectives

Surfactant self-assembly is an important phenomenon that occurs in a number of processes in our everyday life. It is important to understand the forces and parameters that control and influence the self-assembly, as this knowledge can be used both in order to design surfactant systems with desired properties and for creating model systems, for example for biological processes. The papers of this t

The article analyses the role of the historical dimension in official Swedish debate, with a focus on the Swedish government's Living History information project on the Holocaust

Strain has frequently been suggested to play an important role in the function of several proteins. In this paper, we review various definition of strain and discuss how it may be quantified. We show that covalent strain (i.e. strain caused by covalent interactions) plays a minor role for the function of all proteins we have studied, e.g. blue copper proteins, desulforedoxin, CuA in cytochrome c o

BCJR based source coding of image residuals is investigated. From a trellis representation of the residual, a joint source-channel coding system is formed. Then the BCJR algorithm is applied to find the MAP encoding. MAP and minimized squared error encoding are compared. The novelty of this work is the use of the BCJR algorithm and the MAP criterion in the source coding procedure. The source encod
