This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the
Introduction: Many countries in the world are still facing high maternal mortality rates and women still die due to preventable pregnancy- and birth-related causes. This could be prevented with an improvement in the quality of care and yet many countries, especially in the rural areas, have challenges in doing so. In order to understand why is care given in certain way, more qualitative studies ne
Utbrottet av den globala pandemin våren 2020, inneburit omvälvande förändringar för i stort sett alla människor och verksamheter. Privilegier som fri rörlighet och mötesfrihet har sedan utbrottet bytts ut mot strikta restriktioner i de flesta länder vilket drivit många branscher in i krisläge och därmed förändringsarbete. Fastighetsbranschen är inget undantag. Sedan folkhälsomyndigheten rekommenSince the outbreak of the pandemic early 2020, the world has experienced disruptive change in many of its foundations. Privileges as free movement, the freedom of assembly and simply being able to go to the movies have been replaced by strict local and national policies, limiting humans and companies. The Covid-19 agenda has forced a lot of businesses into crisis mode with transformation as a cons
Increased awareness regarding nutrition, environmental sustainability, and animal welfare has sparked a trend to shift away from animal proteins. The phenomenon is referred to as the protein shift and has resulted in a higher demand for alternative protein sources. This dissertation aims to study potential opportunities and challenges of using recombinant food proteins expressed in Escherichia col
A significant proportion of the diversity of species seen today are insects and their host plants, and the evolutionary mechanisms behind their radiation have long captured the interest of biologists. The peacock flies of the large genus Tephritis (Tephritidae) use different host plants in the family Asteraceae for their reproduction. There is variation both in use of host plant species and in the
Byggnadssektorn stod för 39 % av energi- och processrelaterade koldioxidutsläpp år 2018 och globala utsläpp från byggnader ökade med 2 % för det andra året i rad. Därför är det viktigt att ta fram lösningar på byggnadsdesign som minimerar klimatpåverkan från byggnader. Samtidigt som produktionen av bostäder och kommersiella byggnader måste vara kostnadseffektiv för att skapa boende och arbetsplatsThe building and construction sector accounted for 39% of energy and process-related carbon dioxide emissions in 2018 and global emissions from buildings increased by 2% for the second consecutive year. It is therefore important to find building design solutions that minimise the climate impact of buildings. At the same time, the production of residential houses and commercial buildings must be co
Genom en rättsdogmatisk och rättsanalytisk metod undersöker denna uppsats hur undantaget för text- och datautvinning (TDM) i 15 a § lag (1960:729) om upphovsrätt till litterära och konstnärliga verk (upphovsrättslagen, URL) ska tolkas i relation till träning av generativ artificiell intelligens. Uppsatsen behandlar även huruvida den nuvarande regleringen ger en balanserad avvägning mellan upphovsrUsing a legal dogmatic and legal analytical approach, this thesis examines how the exception for text and data mining (TDM) in section 15a of the Swedish Act (1960:729) on Copyright in Literary and Artistic Works should be interpreted in relation to the training of generative artificial intelligence. It also addresses whether the current regulation provides a balanced trade-off between copyright p
This thesis examines the evolution of markups among the largest publicly listed firms in Sweden, represented by the OMXS30 index, during the period surrounding the COVID-19 pandemic from 2018 to 2024. The study assesses whether changes in firms’ pricing power contributed to Sweden’s inflationary and subsequent disinflationary dynamics. Using a microeconomic production function approach developed b
The main purpose of the project has been to find the root cause to the failure of a machine component used to secure some vital parts (later on referred to as the pins) of a packing machine. It was already known that the failure had to do with fatigue, but the actual mechanisms were quite unknown. Measurements on the components did not indicate forces that should lead to failure. The components of
An accessible bicycle-network is a prerequisite to get people start cycling. Increased cycling conduces to a sustainable society with better environment, human health and a more pleasant street environment with reduced congestion. Prioritisation of cycle-routes must be widespread. Just one high quality cycling-line is not enough; the whole bicycle-network needs to carry out high standards. To incr
BACKGROUND: Non-operative treatment for acute appendicitis (AA) in children has gained acceptance as an alternative to surgery in selected cases. Accurate preoperative differentiation between perforated and non-perforated AA is increasingly important, as the former requires emergency surgery while the latter may be managed conservatively. Previous research has suggested that low plasma sodium conc
SARS [Severe Acute Respiratory Syndrome] penetrated China in spring of 2003, created havoc in the social society, exposed weaknesses within the political system and pushed the nation towards a crisis of confidence. At the same time the crisis revitalised the Party's position, brought people from different social stratum together and had a beneficial impact on the populace's knowledge on he
Many coastal areas in Vietnam suffer from erosion. One of the worst affected areas is the Hai Hau beach, located in the Red River delta in northern Vietnam. Over the last hundred years, vast parts of the beach have eroded at an average rate of approximately 25 m per year. Important agricultural land has vanished into the sea and families have been forced to abandon their houses. The cause of the
Populärvetenskaplig sammanfattning: Den ökande växthuseffekten, med påföljande klimatförändringar, framträder alltmer som ett av vår tids största miljöproblem. På grund av människans industriella och agrikulturella aktiviteter har atmosfärskoncentrationen av de viktiga växthusgaserna koldioxid (CO2), metan (CH4) och lustgas (N2O) ökat drastiskt. Med hjälp av modeller och beräkningar förutspås det Northern peatlands are important in the context of the climate change. Since they comprise huge amounts of soil organic carbon and are found where the most significant greenhouse warming is predicted, they have the potential to exert major feedback effects on the global warming. Studies of the greenhouse gas exchange in northern peatlands have mainly focused on the growing season when the soil is
Art funds are gaining traction as an alternative asset class, yet investors must often weigh financial returns against ethical objectives such as promoting diversity in the art market. This bachelor’s thesis investigates how these two motives interact by asking: How do ethical and financial drivers shape individual investors’ willingness to allocate capital to art funds? A two-part online survey
Utvecklingen av autonoma fartyg (‘MASS’) innebär betydande utmaningar för det befintliga systemet för sjörättsligt ansvar. Culpabaserat ansvar och begreppet vårdslöshet är traditionellt uppbyggda kring bedömningen av mänskligt handlande, beslutsfattande och kontroll. Detta väcker frågor om huruvida vårdslöshet och culpa fortfarande är begreppsmässigt sammanhängande när operativa beslut fattas av aThe development of Maritime Autonomous Surface Ships (‘MASS’) presents significant challenges to the existing framework of maritime liability law. Fault-based liability and the concept of negligence are traditionally structured around the assessment of human conduct, decision-making and control. This raises the question of whether negligence and fault remain conceptually coherent where operational
Direct-to-Device (D2D) communication in Non-Terrestrial Networks (NTNs) enables smartphones to connect directly to satellites, extending wireless coverage beyond terrestrial networks. This thesis presents the design of a smartphone antenna optimized for NTN operation, followed by a link budget analysis and Electromagnetic Field (EMF) exposure assessment. The proposed solution is a dual-band circu
Spiral galaxies host elongated filamentary structures of dense gas and dust, known as feathers, which branch off the main spiral arms into the interarm regions and are associated with star formation. The physical mechanisms governing their formation remain debated, with magnetic fields proposed as one of the contributing factors. This thesis investigates the role of magnetic fields in feather form
Researchers and civil society have proposed separating targets for emissions reductions and carbon dioxide removal to prevent mitigation deterrence – the risk that the anticipation of future removals delays decarbonisation. In 2017, Sweden became the first state to adopt separated targets, specifying that its 2045 net-zero target must be reached through a minimum of 85% domestic emissions reductio
Om sakerna på ditt skrivbord inte har tillverkats genom skärande bearbetning, så har definitivt verktyget som användes för att tillverka dem gjort det. Skärande bearbetning har en stor men ganska dold inverkan på ditt liv. Då den enda skärande bearbetning du kanske har upplevt är att göra en ljusstake i träslöjden i grundskolan. Svarvningen och fräsningen i denna avhandling rör ej ljusstakar i träIn an era where 3D printing and AI are at the forefront, turning, milling, and metal cutting might seem like niche research topics from the past. But metal cutting is all around you. If what you have lying on your desk was not machined, then the tools used to create it certainly were. Even 3D-printed or additively manufactured parts must be machined if a good surface quality is needed for an indus
