Correct time and frequency synchronization is important for the performance of orthogonal frequency division multiplex (OFDM) systems. We evaluate a system where a pseudonoise sequence (PN-sequence) is used for estimation of these synchronization parameters. The PN-sequence is superimposed on the OFDM signal. The system is evaluated by means of the variance of the frequency estimation error and th
The paper presents TrueTime, aMatlab/Simulink-based simulator for real-time controlsystems. TrueTime makes it possible to simulate the temporalbehavior of multi-tasking real-time kernels containing controllertasks and to study the effects of CPU and network scheduling on controlperformance. The simulated real-time kernel is event-driven and canhandle external interrupts as well as fine-grained det
Experiments were performed on the central body rich-pilotlean (RPL) burner of a Siemens Industrial Turbomachinary 4th generation DLE combustor to observe the combustion changes that may occur when using fuels other than natural gas. Measurements were taken of temperatures at multiple points along the RPL body while hydroxyl (OH) radical distribution extending from the dump plane of the burner was
The burial and gathering site Almhov was discovered as a result of large-scale archaeological excavations in southern Sweden revealing the remains of five long barrows, two dolmens and a large number of pits, rich in finds. Given the multitude of activities performed at the site including, for example, monument-building, pit-digging, burying, feasting and axe-manufacturing, the site can serve as a
Random amplified polymorhic DNA (RAPD) is a PCR-based marker system that makes use of universal sets of short oligonucleotides that amplify random DNA fragments under low-stringency conditions. The RAPD marker system has found widespread use and possesses a number of very positive features, being a multiplex and universal system. The present studies characterize and evaluate the properties of the
Glesbygden påverkas av skatterna.
Huvudsyftet med denna rapport är att söka samband mellan studieresultaten under det första läsåret vid de nya femåriga civilingenjörsprogrammen vid LTH och gymnasiebetygen – både det totala samt det i matematik. Sådana samband mellan gymnasiebetyg och resultat på första gemensamma matematiktentamen är tydliga – mer så för matematikbetygen från gymnasiet eftersom fler betyg i de lägre kategorierna
Rapporten redovisar data om hur SI-verksamheten vid fem civilingenjörsprogram vid LTH inverkar på studieresultaten under det första läsåret samt på resultaten i en inledande matematikkurs till vilken SI-verksamheten är knuten. SI står för SamverkansInlärning och är en metod där en äldre student ”coachar” en grupp med nya studenter till att diskutera och lösa problem i ett ämne. Metoden syftar vid
The infrared beamline at MAX-lab in Lund is equipped with a Bruker Hyperion 3000 microscope combined with an IFS/66v FTIR instrument. In combination with a number of different detectors and objectives this makes it possible to study a large number of different samples. For example there is a FPA detector for mapping larger areas and a Bolometer for measurements in the far infrared. A number of exa
Popular Abstract in Swedish I den här avhandlingen behandlas olika aspekter av gelfria metoder för proteomanalys med masspektrometri, med tonvikt på inmärkningsmetoder. Arbetet är baserat på tre artiklar, där olika effekter vid inmärkning på peptider utreds, samt framtagningen av en ny typ av inmärkningsstrategi beskrivs. Kemisk inmärkning har haft stor betydelse för peptidbaserad proteomik eftersIn this thesis different aspects of gel free procedures for mass spectrometry based proteome analysis are addressed, with emphasis on labelling techniques. It is based on three original articles where the effects imposed onto peptides upon modification are investigated, and the development of a new type of labelling strategy is described. Chemical modification has been of great importance for the
This article aims to contribute to the rich literature on neoliberalization and trade unions in Mexico by providing an examination of the contradictory relationships between capital, trade unions and the workers they represent, in a Swedish-based transnational corporation. The article investigates how the broader international relationships of dependency and exploitation are lived by workers and t
Description of the history of research and the results of investigations of Sweden's only prehistoric flint mines at Södra Sallerup, southern Sweden.
Frogs are often rare or absent from intensively farmed areas. Here we explore the possibility that the landscape and the quality of the terrestrial habitat are unsuitable for these populations. Spawn of Rana arvalis and R. temporaria was introduced into ponds in a south Swedish agricultural landscape in 2003 (eight ponds) and 2004 (ten ponds). Metamorphs emerged from nine (R. a.) and 12 (R. t.) of
Ett flertal studier av svensk kommunal praktik pekar på betydelsen av att kommuner anpassar sig till förändrade förutsättningar (se till exempel Brorström och Siverbo 2008, Hellström med flera 2009). En del av dessa förändringar kan vara mer eller mindre tvingande, såsom förändringar i de lagar som omgärdar kommunal verksamhet, medan andra kan vara mer eller mindre frivilliga. Förändringar sker e
