Popular Abstract in Swedish Avhandlingen Optimization of Low-Level Controllers and High-Level Polymer Grade Changes är inom ämnesområdet reglerteknik. Det centrala i ämnet reglerteknik är att styra ett system, såsom en motor, ett teleskop eller en kemisk reaktor, så att det uppför sig på ett önskvärt sätt. Detta görs genom att använda mätningar av systemet, en algoritm som beräknar hur systemet sTwo design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID contr

Sub Saharan African (SSA) countries are facing severe economic challenges such as high trade costs, poor trade performance and low growth levels. As a result development assistance is needed to overcome these difficulties. SSA countries receive the highest share of Aid for Trade (AfT) and therefore it is important to assess the effects of AfT. This study investigates the trade effect of AfT on tra

This study focuses on the phenomenon of formality marriage xinghun in contemporary post-socialist China. This practice is becoming more and more common among LGBT individuals, namely gay men and lesbian women. The research aims to unveil and inquiry the mechanism working behind such practice, focusing on the factors influencing the choice to undergo xinghun, the search for xinghun partner and the

Within the issue area of lobbying dynamics in the European Union, the measurement of interest group success is heavily debated among scholars. This research examines the influence interest groups had in shaping the Artificial Intelligence Act via the Public Consultation process. In contrast to existing literature, a computer assisted quantitative content analysis was used to gain insights into lob

Souvenir shopping is inseparably a part of tourist activity. Recently, Indonesia has observed the phenomenon where famous Indonesian celebrities engage in entrepreneurship and open their own cake shops in tourist destination cities. They describe their product as a novel specialty food souvenir. The tourist activity of purchasing and gift-giving celebrity cakes to others is linked to a consumption

Syftet med studien var att kvalitativt undersöka kvinnliga fotbollsspelares upplevelse av att nå elitnivå. Semistrukturerade intervjuer användes och totalt intervjuades tre deltagare. Intervjuerna analyserades med IPA (Interpretative Phenomenological Analysis) som metodologisk ansats. Totalt kunde fem teman urskiljas som centrala i upplevelsen av elitnivå: tankar och känslor kopplade till övergångThe purpose of this study was to qualitatively explore the experience of reaching the elite level for women in football. Semi-structured interviews were conducted with three participants. The interviews were analysed using Interpretative Phenomenological Analysis (IPA). In total, five themes emerged: thoughts and feelings associated with reaching the elite level, social support, gender identity, m

Barnahus is a Nordic model for collaboration between different authorities regarding the issue of child victims of crime. As this means that different work logics interact, some argue that Barnahus can be seen as affected by juridification, which is a term that describes how law enforcement is prioritized over care-oriented services. The purpose of this study was to explore how coordinators of dif

Purpose: The aim of this thesis is to investigate the effects of CEO narcissism in relation to corporate performance and whether there are distinct differences between companies earlier in the corporate life cycle and more mature firms. Methodology: This thesis uses quantitative method with a deductive approach. Five regression models were constructed to investigate the research question. Theore

We study the geometric significance of Leinster’s magnitude invariant. For closed manifolds we find a precise relation with Brylinski’s beta function and therefore with classical invariants of knots and submanifolds. In the special case of compact homogeneous spaces we obtain an elementary proof that the residues of the beta function contain the same geometric information as the asymptotic expansi

In this first episode of the podcast Nic and Rebecca invite Michiel Lambrechts to the mic and chat to him about planet formation.  Thereafter they take a closer look at one of their favourite astronomical objects: Le Verrier's planet.

Lunds universitet fick i uppdrag av Kemikalieinspektionen att kartlägga och beskriva ansatser till metoder som bedömer indirekta effekter av växtskyddsmedel på individer och populationer och studier som utvärderar om nuvarande riskbedömningsmetoder är tillräckliga för att bedöma direkta effekter av växtskyddsmedel på biologisk mångfald. Uppdraget utfördes i två delar. För det första inventerade viLund University was commissioned by the Swedish Chemicals Agency to map and describe emerging methodologies that assess the indirect impact of plant protection products on nontarget organism individuals and populations, and studies that evaluates if current risk assessment methodologies are sufficient to assess direct effects of plant protection products on biodiversity. The commission was perform

Importance: Lack of arachidonic acid (AA) and docosahexaenoic acid (DHA) after extremely preterm birth may contribute to preterm morbidity, including retinopathy of prematurity (ROP).Objective: To determine whether enteral supplementation with fatty acids from birth to 40 weeks' postmenstrual age reduces ROP in extremely preterm infants.Design, Setting, and Participants: The Mega Donna Mega trial,

BACKGROUND: Phosphatidylethanol (PEth) is an alcohol use biomarker with higher clinical sensitivity and specificity than commonly used alcohol markers. Since its introduction as a clinical alcohol-marker in 2006, the number of samples sent to our laboratory for the determination of PEth has shown a strong annual increase. This has prompted the need to develop a cost-effective and reliable analytic

Healthcare in Sweden is dealing with problems regarding accessibility for patients. Moreover, there is a lack of an overall model concerning matching specialist care to patients. Against this background, the purpose was to develop a preliminary healthcare matching model and discuss the barriers of this model. Theoretically, the study draws on the concepts of matching and coordination completed wit

This is an overview article regarding artificial intelligence (AI) and its potential normative implications. Technology has always had inherent normative consequences not least due to AI and the use of algorithms. There is a crucial difference between algorithms in a technical sense and from a social-science perspective. It is a question of different orders of normativity - the first related to th

Objective: To investigate the dynamic changes of soluble fms-like tyrosine kinase−1 (sFlt−1), placental growth factor (PlGF) and their ratio in maternal plasma, from preeclampsia diagnosis to postpartum, evaluating its clinical utility. Methods: Single-center prospective longitudinal cohort study with repeated sample collection in women with established preeclampsia (PE). Seventy-five (n = 75) wom

In a north European context, identifying invasive species is far from trivial because the vegetation has been influenced by human activities for thousands of years. New species have immigrated continuously since the end of the last glaciation, both spontaneously and through direct or indirect help by man. Still, newly immigrated species may be problematic in a nature conservation context and may h
