Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic

This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. It is a narrow band filter designed for the American digital mobile telephone system accordin

Frequency-Domain Iterative Learning Control of a Marine Vibrator

To the purpose of marine seismic acquisition, new acoustic sources have been developed to reduce the environmental impact. The use of marine vibrators makes it possible to define emission frequency ranges, consequently allowing limitation of the frequencies that disturb marine animal life. Constructing marine vibrators with high efficiency and linear dynamics is however difficult, and the vibrator

Gaia and the Astrometric Global Iterative Solution

Gaia is an ESA space astrometry mission due for launch in 2011-12. We describe part of the work carried out in the Gaia Data Processing and Analysis Consortium, namely the Astrometric Global Iterative Solution (AGIS) currently being implemented at the European Space Astronomy Center (ESAC) in Spain and largely based on algorithms developed at Lund Observatory. Some provisional results based on sim

The Immorality of Emotional Response. Liberty and the Slavery Metaphor in Wollstonecraft’s Theory of Property

I am concerned with Mary Wollstonecraft’s political morality. In it she makes no moral room, I claim, for emotional responses or emotional reasons for action, and it is important that she doesn’t. I will start by pointing at reasons for why it is important. I will then go on to analyse the content of and relations between her main political concepts: the triad of liberty, equality and virtue, with

Integration and creative experiences after a merger of two organizations within the Social Insurance Service : A longitudinal group perspective

Popular Abstract in Swedish Organisationssammanslagningar är vanligt förekommande inom såväl offentlig som privat verksamhet. Effekterna för de anställda och för organisationerna är beroende av hur integrationsprocessen förlöper. En korsbefruktning kan äga rum när idéer och arbetssätt möts efter sammanslagningen. Syftet med avhandlingen är att analysera integrationsprocessen och undersöka om den kMergers of organizations are a widespread phenomenon in the public as well as in the private sector. The individual and the organizational outcomes are dependent on the success of the integration process. During the integration after a merger, a cross-fertilization of ideas, working methods etc. is possible and could pave the way for creative processes. The aim of the present thesis is to analyze

Organometallic complexes with antimalarial properties

Popular Abstract in Swedish Malaria är en allvarlig febersjukdom som varje år drabbar nästan 250 miljoner människor. Sjukdomen är mycket utbredd inom tropiska och subtropiska delar av världen och världshälsoorganisationen (WHO) har beräknat att strax under en miljon människor, majoriteten av dem barn, dör av malaria varje år. Malaria har följt människan under mycket lång tid och var länge vanlig iMalaria is a serious disease that causes around 800 000 deaths per year. Current malaria control efforts are hampered by the widespread resistance to common antimalarial drugs, such as the 4-aminoquinoline derivative called chloroquine. Previous research has shown that specific modifications of chloroquine, including inclusion of organometallic fragments into the organic framework, can result in c

Flint and Groundstone Axes in the Scanian Neolithic. An evaluation of raw materials based on experiment

One of the most common Neolithic tool types in Scandinavia which is available to us for study today is the axe. Judging by the thousands of such axes found in museum collections, this tool was an important part of Neolithic man's toolkit. While most of the axes which are considered primarily work axes (as opposed to the more ceremonial so-called battle axes) are made of flint, other, non-flint mat

Multilinear Constraints in the Infinitesimal-time Case

In this paper we study the infinitesimal-time case of the so called multilinear constraints that exist for each subsequence in a sequence of images. These constraints link the infinitesimal motion of the image points with the infinitesimal viewer motion. The analysis is done both for calibrated and uncalibrated cameras. Two simplifications are also presented for the uncalibrated camera case. One s
