The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and
This thesis evaluates the risk parity and tail-risk parity approach against conventional weight budgeting approach. The risk parity and tail-risk parity approach, in contrast to weight budgeting approach, is about distributing the risk between the asset classes in the portfolio. The risk, is traditionally measured in terms of volatility together with the assumption that returns follows a Gaussian
The present study explores the value and role of the physical space of the public library from the perspective of the visitors in the context of digitalization. The qualitative research was based on semi-structured interviews with regular visitors of Idé A Drottninghög (Helsingborg, Sweden), Idé A library staff members, and collaborative organizations of Idé A that make use of the library’s physic

Clinical outcome data of patients discharged after Coronavirus disease 2019 (COVID-19) are limited and no study has evaluated predictors of cardiovascular prognosis in this setting. Our aim was to assess short-term mortality and cardiovascular outcome after hospitalization for COVID-19. A prospective cohort of 296 consecutive patients discharged after COVID-19 from two Italian institutions during
Integration of emerging membrane processes [i.e., forward osmosis (FO), membrane distillation (MD), reverse electrodialysis (RED)] and mature membrane processes [i.e., reverse osmosis (RO)] can address the need for efficient desalination solutions. Utilization of different membrane units in pre- and post-treatment stages allows lowering the energy requirements and environmental impacts of the proc
Billions of birds migrate every year. To conduct a successful migration, birds undergo a multitude of physiological adaptions. One such adaptation includes adjustments of immune function, however, little is known about intraspecies (between-individual) and interspecies (between-species) variation in immune modulations during migration. Here, we explore if early and late migrating individuals diffe
BackgroundThere is a large unused potential for risk reduction in the preoperative period via effective lifestyle intervention targeting co-existing risky lifestyles: Smoking, malNutrition, obesity, risky Alcohol intake and insufficient Physical activity (SNAP).This trial compares the efficacy of the integrated STRONG programme with standard care on preoperative risk reduction and secondly on SNAP
INTRODUCTION: The FEV1 quotient (FEV1Q), calculated as the index between FEV1 and a theoretical lower survivable FEV1 threshold of 0.4L for females and 0.5L for males, has been investigated as a novel method of interpreting results from lung function testing. The applicability of the FEV1Q in populations with chronic respiratory failure has not been studied, and the continuous association between
Objective: This study aims to provide a deeper understanding of what persons with lived experience and professionals with experience of patient safety, suicide research, and investigations consider to be most important in investigations of healthcare before suicide to learn and improve the care of suicidal patients. Method: This is a qualitative study based on 15 semistructured interviews with per
Background: Traditionally managed semi-natural pastures are recognised for their high biodiversity. One drawback is that these pastures are often low in fodder production and hence rather unprofitable, which may lead to abandonment. Two ways to increase production and profitability and maintain grazing are to (i) offer the grazers supplementary feed, or (ii) co-enclose the semi-natural pasture wit
Popular Abstract in English Look around and notice how many items have been manufactured or transported using petroleum-based products. In modern life, it is almost an impossible task to exclude them from our daily routine. They are present in plastics, cosmetics, cleaning products, medicaments, food, etc. To diminish our dependence on the demanded black liquid, a lot of research efforts have beenDepletion of easily accessible fossil energy resources, threat of climate change and political priority to achieve energy self-sufficiency and sustainable solutions prioritize a conscious and smart use of renewable resources to generate a bio-based economy. Bio-based compounds can replace chemicals and fuels that are now mainly produced from crude oil. Efficient processes for the conversion of pla

Popular Abstract in Swedish Till processindustrin räknar man bland annat fabriker som tillverkar papper, plast och livsmedel. I en enda fabrik kan det finnas tusentals PID-regulatorer som har till uppgift att styra storheter som tryck, flöden och temperaturer till önskade värden. PID-regulatorns roll i processindustrin har därför jämförts med den arbetsmyran har i myrstacken. Huruvida en enskild mA large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller. This thesis presents tools for analys
Background and purpose To evaluate the patterns of failure following clinical introduction of amino-acid O-(2-[18F]fluoroethyl)-L-tyrosine (FET)-PET-guided target definition for radiotherapy (RT) of glioblastoma patients. Materials and methods The first 66 consecutive patients with confirmed histology, scanned using FET-PET/CT and MRI were selected for evaluation. Chemo-radiotherapy was delivered
Purpose: Recent studies have highlighted the importance of adopting a contingency approach to configuring omnichannel warehouses. Nonetheless, research on how various contextual factors influence the selection of warehouse configuration is scarce. This study fills this knowledge gap by exploring how and why certain configurations fit in different omnichannel contexts. Design/methodology/approach:
An RH method was proposed in the late 1970s to replace the traditional CM-method in Sweden and from 1984 the RH-method is the dominating method to measure moisture in concrete floors before applying a moisture sensitive floor covering. The required total uncertainty must be smaller than 2-3 % RH depending on the method used. The paper describes the historical development of RH measurements in conc
Within the next thirty years, two thirds of the human population will live in a city. This growing urban population requires a major shift in the way we produce and distribute food, since industrial agriculture practices contribute to climate change, biodiversity losses, pollution of waterways, soil degradation, etc. Urban and peri-urban agriculture and forestry (UPAF) represent one of the strateg
