Mobile communications have evolved with the commercial deployment of 5G and initial studies of 6G. New solutions and innovative technologies are being incorporated to reach the target requirements. One of the key technologies in mobile networks is massive multiple-input-multiple-output (MIMO). Increasing the number of antennas offers significant benefits in coverage, reliability, and spectral effi
Digital watermarking is done by adding a piece of data to a signal, which depending on the target media type, may be a picture, audio or video signal. The purpose of this additional signal is to provide a consistent signature linked to the original source which then remains through the act of copying. This allows the author to obstruct the act of theft by adding this signal to his or her creation.
In August 2007 we went to New Zealand for a placement at Child Youth and Family Services. There our interest in Family Group Conferences (FGC) took off. FGC is not near as common in Sweden as in New Zealand. Therefore the purpose of this study was to examine how the Social Services in Helsingborg and Höör in Sweden and Belfast in Northern Ireland work with FGC. We had the privilege to go to Belfas
Constraining past changes in the strength and configuration of the geomagnetic field provides a valuable perspective on the processes that govern the geodynamo. Here we update a modelled dipole tilt reconstruction for the last 9000 years by using palaeomagnetic records that originate from globally well-distributed sites. Some features predicted by earlier dipole models become more distinct due to
Abstract Background: Velopharyngeal dysfunction (VPD) can have various causes and may be a significant disability for the affected patient. Treatment options include surgery and speech therapy, but the success rates are often inconsistent. Methods: In this study, self-assessment questionnaires were sent out to 222 Swedish patients with VPD. The questionnaire included questions about satisfaction w
The anticoagulant vitamin K-dependent protein S (PS) circulates in plasma in two forms, 30% free and 70% being bound to the complement regulatory protein C4b-binding protein (C4BP). The major C4BP isoform consists of 7 alpha-chains and 1 beta-chain (C4BP beta(+)), the chains being linked by disulfide bridges. PS binds to the beta-chain with high affinity. In plasma, PS is in molar excess over C4BP
Denna rapport är skriven inom kursen ”VBRN70 - Brandteknisk riskvärdering” vid Lunds Tekniska Högskola. Rapporten omfattar en brand- och utrymningsanalys av Kungliga Dramatiska Teatern i Stockholm med fokus på personsäkerhet. Analysen inleddes med ett platsbesök för att få bättre kännedom om objektet. Utifrån observationer från platsbesöket och tillgänglig statistik identifierades därefter flertaThis report is a part of the course ”VBRN70 - Brandteknisk riskvärdering” given by Lund University of Technology. The report presents a fire and risk evaluation of the Royal Dramatical Theatre in Stockholm with focus on the safety of people in the building. The analysis started with a site visit to gain more knowledge of the object. From observations from the visit and available statistics on fi
Plastic pollution is a severe global problem and every year approximately 368 million tons of plastic is produced. Both terrestrial and marine environments are impacted and hundreds of species affected. Marine plastic debris accounts for a weight of 268 940 tons and affects hundreds of marine species through habitat degradation, entanglement and ingestion. Microplastics (MPs) are a type of plastic
During the Secret War in Laos, 1964-1973, the United States dropped approximately 2 million tons of bombs in Laos. However, 30% of the employed bombs failed to detonate. It is estimated that 78 million unexploded ordance (UXO) still contaminate the land of Laos. This paper therefore aims to explore how UXO affect the possibilities for the rural population in Houamoung district to attain a sustaina
I takt med att hållbarhet blir viktigare söker många företag inom jordbrukssektorn lösningar för att fasa ut fossila drivmedel. Utmaningen blir ännu mer komplex när ersättningen ska vara kompatibel med en existerande fordonsflotta, utan investering i nya fordon. Denna studie jämförde fyra kommersiellt tillgängliga och förnybara drivmedel med referensbränslet diesel. De undersökta drivmedlen är HVAs sustainability becomes more important in today's society, many companies in the agricultural sector are looking for new alternatives to fossil fuels. The challenge becomes even more complex when the replacement must be compatible with an existing vehicle fleet, without requiring new investments in vehicles. This report compares four commercially available and renewable fuels, using convent
This thesis explores a range of control algorithms for multimodal acoustophoresis, the process of manipulating particles in a fluid by simultaneously using several acoustic modes. The aim of the algorithms is to precisely guide particle trajectories in acoustofluidic systems, motivated by the demand for non-invasive, scalable manipulation techniques in biomedical applications such as single-cell a
This master’s thesis is a qualitative content analysis of nine municipal library plans (and two county library plans) with a basis in new institutionalism, specifically in regards to legitimacy, homogeneity as well as themes and patterns in the sourcematerial. With a basis in the history of the library plan and the municipal gouvernance, debate in regards to cultural policy, the downsizing of libr
Oats (Avena sativa) are a valued food product due to their nutritional profile and proven health benefits. However, prior to consumption, they require heat processing to prevent off-flavors and undesirable mouthfeel caused by lipase-catalyzed hydrolysis of lipids. While the heat treatment inactivates lipases, it raises concerns regarding sustainability and oat quality. The discovery of novel funct
Fingerprint recognition has become a popular authentication method in modern smartphones, replacing traditional passwords and PINs. However, smartphone fingerprint sensors are small and capture only partial fingerprints with limited resolution. Combined with varying image quality and inconsistent finger placement, multiple images must be stored per user to ensure reliable authentication. During ve
Background/Aims: To identify prodromal Alzheimer's disease (AD) subjects using a data-driven approach to determine cognitive profiles in mild cognitive impairment (MCI). Methods: A total of 881 MCI subjects were recruited from 20 memory clinics and followed for up to 5 years. Outcome measures included cognitive variables, conversion to AD, and biomarkers (e. g. CSF, and MRI markers). Two hierarchi
Shunting yards are one of the main areas impacting the reliability of rail freight networks, and delayed departures from shunting yards can further also affect the punctuality of mixed-traffic networks. Methods for automatic detection of departures, which are likely to be delayed, can therefore contribute towards increasing the reliability and punctuality of both freight and passenger services. In
Obstructive sleep apnea (OSA) is common in patients with coronary artery disease (CAD), in which inflammatory activity has a crucial role. The manifestation of OSA varies significantly between individuals in clinical cohorts; not all adults with OSA demonstrate the same set of symp-toms; i.e., excessive daytime sleepiness (EDS) and/or increased levels of inflammatory biomarkers. The further explor
