Two 130nm CMOS VCOs with ferroelectric varactors are presented. The cross-coupled VCO-cores are flip-chip mounted on silicon carriers with integrated inductors and tunable ferroelectric varactors. The output frequency of the first VCO is tunable from 23.4 GHz to 26.1 GHz, corresponding to a tuning range of 11 %. The phase noise of this VCO, tuned to its center frequency, measures -117 dBC/Hz at 1
Popular Abstract in Swedish I mitt arbete som transplantationskoordinator på Kliniken för njurmedicin och transplantation på Universitetssjukhuset MAS i Malmö kommer jag i kontakt med många patienter som väntar på njurtransplantation. Det ingår i mitt arbete att informera dessa patienter inför uppsättning på väntelistan för njurtransplantation. En annan av mina arbetsuppgifter är att koordinera ocGreat efforts have been made to find solutions to the shortage of organs, such as extending the donor pool by accepting so-called marginal donors and development of transplantation of organs from animals (xenotransplantation, xt). Due to the scarcity of organs, there is a long tradition of prioritizing among patients on the waiting list for transplantation. Rules for allocation of organs have been
Popular Abstract in English The aim of this thesis is to search for the origins of groups stars with similar kinematics making use of their chemical information. Based on measured elemental abundances from high-resolution spectra, a modified chemical tagging method is used to identify the potential cluster members in two cases. In first case, we employ this method to search for the lost siblings oMost of field stars originate from dissolved star clusters. If the gas cloud is well mixed the stars in the cluster are expected to be chemically homogenous. Although the original kinematical information of a star may be lost under the Galactic dynamic evolution, the chemical signatures are preserved in the form of elemental abundances in individual low-mass stars. The present-day distribution of
Advances in technology have resulted in new and advanced methods to support decision-making. For example, artificial intelligence has enabled people to make better decisions through the use of Intelligent Decision Support Systems (DSS). Emerging research in DSS demonstrates that decision makers can operate in a more timely manner using real-time data, more accurately due to data mining and 'big da
I denna essä söks, utifrån en diskussion om frihet som ett hållbart värde, balansen mellan en respekt för det beständiga och en förståelse för det kontextkänsliga. Hur ska en nutida läsare tolka exempelvis John Lockes eller John Stuart Mills frihetsbegrepp och kan vi egentligen tala om dem som med en samtida? Inga idéer är oberoende av tid och rum, men en djupare insikt i idéernas historiska föran
The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. Special interest was drawn to the dynamic processes such as start-up, r
Föreliggande övningsbok har utarbetats för att underlätta inlärningen och förståelsen av innehållet i huvudboken. Övningsboken innehåller ett antal instuderingsfrågor, som är kopplade till huvudbokens samtliga kapitel. Till drygt hälften av huvudbokens kapitel finns även ett flertal räkneuppgifter. Ett mycket stort antal av dessa har inspirerats av skadefall och andra praktiska problemställningar.
The research history and conditions in experimental archaeology up until today show a heavy emphasis on technological studies within a hypothetical-deductive theoretical paradigm. How is it possible to enhance the conditions for experimental archaeology so that it can also develop as a humanistic area of research, more closely related to existential perspectives of human life? We argue for the int
The thesis is based on five investigations. In the first study the nature and the degree of cognitive impairment of patients with frontotemporal dementia (FTD) is explored. The results from neuropsychological assessment are described as three levels of cognitive impairment. These levels of functional disturbance corresponded to increased severity of abnormality of the regional cerebral blood flow
This book chapter discusses the reactions within a few Christian churches, Judaism and Islam to a number of recent biotechnological interventions: assisted reproduction, embryonic stem cells, genetic intervention, cloning, and organ transplantation.
