This paper presents a systematic investigation of the influence of streamturbulence on the pressure forces on a single tube. Grids were used to producedifferent turbulent flow fields with longitudinal integral scale (eddy size)ranging from 0.1 to 0.5 tube diameters and turbulence intensities ranging from0.1 to 3-2 %. The measurements were carried out at two Reynolds numbers, 2.7 - 10 and U.1-104 ,
Cancer develops through a process of somatic evolution1,2. Sequencing data from a single biopsy represent a snapshot of this process that can reveal the timing of specific genomic aberrations and the changing influence of mutational processes3. Here, by whole-genome sequencing analysis of 2,658 cancers as part of the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Canc
In this paper, we show that a software implementation of IND-CCA-secure Saber key encapsulation mechanism protected by first-order masking and shuffling can be broken by deep learning-based power analysis. Using an ensemble of deep neural networks trained at the profiling stage, we can recover the session key and the secret key from 257 × N and 24 × 257 × N traces, respectively, where N is the num
A search with minimal model dependence for physics beyond the Standard Model in events featuring three or four charged leptons (3ℓ and 4ℓ, ℓ=e,μ) is presented. The analysis aims to be sensitive to a wide range of potential new-physics theories simultaneously. This analysis uses data from pp collisions delivered by the Large Hadron Collider at a centre-of-mass energy of s=13 TeV and recorded with t
Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state1–13. Over the past decades, these invariants have come to play a central role in describing matter, providing the foundation for understanding superfluids5, magnets6,7, the quantum Hall effect3,8, topological insulators9,10, Weyl semimetals11–13 and other p
Introduction: The rise in armed conflicts has contributed to an increase in the number of asylum seekers. Prolonged asylum processes may negatively affect asylum seekers’ health and lead to inactivity. Studies show that physical activity interventions are associated with improvements in health outcomes. However, there are a limited number of studies investigating the associations of physical activ
This paper is about how journalists report on teen robbery. Theories like moral panic and problem frame will be used to see how the media works. Those theories will be combined with research on media and on how newspapers reported on an actual teen robbery wave in Sweden during 1998-2002. The study will investigate how journalists working for the paper GT reports on teen robbery during the last th
The unpredictable behaviour of financial time series has long been a concern for econometricians, making it difficult to find appropriate models with a satisfactory fit. The Markov regime switching model is a popular approach, much in behalf of the way it takes the shifts in the time series behaviour into account. The model in this thesis is based on a mixture of normal distributions, extended to
Antibiotic resistance is an ever growing problem, and is considered one of the major challenges of modern medicine. In order to avoid further development and spread of multiresistance among bacteria, the use of antibiotics should be more restrictive, and more tailored to individual cases of infection. To facilitate more directed treatments, it is crucial to be able to quickly and reliably identify
I Aktiebolagslagen finns bestämmelser om tvångslikvidation på grund av kapitalbrist i 25 kap. 13–17 §§ ABL där syftet med bestämmelserna är att sätta upp en gräns för hur långt en förlustbringande verksamhet får fortsättas innan verksamheten måste avbrytas genom likvidation. Kritisk kapitalbrist innebär att bolagets eget kapital understiger hälften av det registrerade aktiekapitalet. Regleringen iThe Swedish Companies Act contains provisions on compulsory liquidation due to capital shortage in Chapter 25, sections 13–17 § ABL where the purpose of the regulations is to set a limit on how far a loss-making activity may be continued before the business must be interrupted by liquidation. Critical capital shortage means that the company's equity is less than half of the registered share ca
To control an accelerating proton beam that travels close to the speed of light, a large number of beam diagnostic instruments are needed. One of the instruments that will be used at the accelerator of the European Spallation Source is a Non-invasive Profile Monitor (NPM). Once installed, this system will measure the transverse beam profile by imaging the fluorescent gas induced by the accelerated
Vid sammansättningen av kameror ställs höga krav på finjustering av sensorn och objektivets relativa position för att den resulterande bilden ska bli skarp. Axisutvecklade nätverkskameror fokuseras, av olika anledningar, i oändligheten. Examensarbetet utvecklar mjukvara för ett nytt verktyg, Modus, som ska användas in-house för att undersöka effekten av kamerans backfokus på bildens skärpa. VerktFix-focal cameras require careful alignment of the sensor relative to the lens during assembly in order to produce a sharp image. Axis developed wide- and fish-eye network cameras are, for a number of reasons, focused at infinity when aligned. This thesis develops the software for a new inhouse tool to be used at Axis to analyze the back-focus effect on the camera’s focus characteristics. The too
Resolving fast events, such as electron dynamics, requires short light pulses. To this date the shortest available light pulses are created using High-order Harmonic Generation (HHG) and have a duration of a few hundred attoseconds (1 as = $10^{-18}$ s). When used for pump-probe experiments, these pulses are generated in an interferometer, which needs to be stable for the experiment to yield high
Within the systematically complex genus Sorbus, repeated hybridization, polyploidization and apomixis has led to a series of intermediate and evolutionary independent species. Sorbus intermedia (Ehrh.) Pers. (Swedish whitebeam) and S hybrida L. (Swedish service tree) are endemic to the Fennoscandian region and are both apomictic polyploid hybrids derived from diploid sexual species. However, their
The Business Intelligence (BI) systems are increasingly becoming an important piece of the puzzle for the success of organizations. That being so, it is important to acknowledge the benefits that can be obtained from the use of such systems. Furthermore, for those who hesitate in investing in BI systems this research presents how the organizations operating in different business fields are using t
The long coherence times of the 4f hyperfine levels of rare-earth-ions gives the possibility to use these as quantum computation devices. Moreover after being doped into a crystal the strong dipole-dipole interaction can be utilized to entangle them. Much work has been done here in Lund to attain as many of the DiVincenzo criteria as possible. At the moment work is being done in the creation of a
This bachelor thesis, “There is nothing hidden behind the mask, the mask is all there is.’ - A netnographic study on influencers’ authenticity and the communication of fashion through YouTube”, aims to understand the conception of authenticity and identity from a fashion perspective through the phenomenon vlogging on YouTube. By applying a netnographic research design, this thesis contains a colle
Within society, sexual abuse is a subject of taboo and has a number of stigmas attached to it which can make it difficult for children to talk about it let alone make a disclosure as typically can be a relative or someone that the child trusts. The aim of this study was to gain a better understanding of how sexual abuse against children is depicted in children’s literature. Within our study we hav
The objective with this master thesis is to analyze how the service life of wood in ground contact, with regard to decay, varies between different test fields. Different factors are evaluated whether it is possible to estimate the service life of a specimen in a specific test field. Also the influence of the climate on the service life in different test fields is investigated by calculated climate
