Background: More than 10% of the global population has a BMI above 35. Bariatric surgery is an efficient way to treat this condition. Unfortunately, there is a risk of nutritional deficiencies. The number of studies after a longer time span is scarce. The aim of this study was to determine the occurrence of anaemia five and ten years after bariatric surgery and how it was related to substitution t

The purpose of this study is to map Key Performance Indicators (KPIs) related to the operation and maintenance of photovoltaic (PV) systems, i.e., solar cells, on commercial buildings. This is investigated through a literature review aimed at gathering and evaluating relevant KPIs. A total of 24 KPIs are identified in the literature review. After evaluation, a selection of these KPIs is used to an

Hearing loss is increasing with an ageing population. There is thus a need for more convenient diagnosis methodology. This thesis investigates whether it is possible to classify age-related hearing loss using speech biomarkers and Automatic Speech Recognition (ASR) or not. The methodology was a binary classification problem based on analysing conversational data between a participant with normal h

This thesis investigates the causal relationships among alarms at the European Spallation Source (ESS), focusing on enhancing alarm management through advanced data analytics. The study explores these relationships using Dynamic Bayesian Networks (DBNs) complemented with well-defined Conditional Probability Distributions (CPTs). This approach models the cascading interactions of alarms based on th

Ever since the end of the second world war, Europe has been lagging behind the United States in rocket development. In particular in the last 10 years, the technological gap and American competitive advantage have grown thanks to SpaceX’s development of reusable launch vehicles. A key enabler for the reusability of booster stages is precise rocket engine control. This thesis addresses the objectiv

Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a

BACKGROUND: HIV viremia has been considered a cardiovascular disease (CVD) risk factor, but many studies have had insufficient data on potential confounders. We explored the association between viremia and CVD after adjusting for established risk factors and analyzed whether consideration of viremia would improve CVD prediction.METHODS: Adults from RESPOND were followed from the first date with av

The IFMIF-DONES Facility is a unique first-class scientific infrastructure whose construction is foreseen in Granada, Spain, in the coming years. Strong integration efforts are being made at the current project phase aiming at harmonizing the ongoing design of the different and complex Systems of the facility. The consolidation of the Diagnostics and Instrumentation, transversal across many of the

Automation and robotics have been widely integrated across various industries, yet the building sector has not seen significant evolution over the last few centuries. This thesis presents a concept for integrating automation at construction sites, specifically for the assembly of wooden prefabricated walls. When working with wooden prefabricated house elements the sizes are typically large, 6-10 m

The efficient allocation of flexible resources, such as grid batteries and wind parks, across multiple energy market auctions, is pivotal for maximizing socio-economic welfare, interpreted here as profits. This study explores various optimization methods, including Linear Programming, Integer Linear Programming, Robust Optimization with Linear Programming, and Robust Optimization with Integer Line

This thesis examines how elastic deformations affect the kinematics and stationary positional and orientational accuracy of an industrial manipulator. The analyzed robot had a wrist design which introduced a coupling between the two wrist joints, i.e., the outermost two joints responsible for orienting the end-effector. This meant that one of the wrist motors had an effect on both joints, and that

The circumstances and constraints under which a problem is solved can affect how people engage in problem solving. Based on that premise this research investigates the effects of motivational music in the context of a dynamic ball-transportation task. In particular, this study explores how music influences distance moved, throwing accuracy, non-linearity, motivation and emotion regulation. 15 part

Vad formar synen på sexualitet hos personer med funktionsnedsättning – både från samhällets sida och hos individen själv? Vilka begränsningar upplever dessa personer när det gäller till exempel dejting, intimitet och föräldraskap? I denna banbrytande bok utforskas ett område som kan vara känsligt och tabubelagt: relationen mellan funktionsnedsättning och sexualitet.Funktionshinder och sexualitet g

This paper explores the role of migrant networks on the occupa-tional earnings of Swedish male immigrants in the United Statesfrom 1900 to 1920. Using data from full-count U.S. censuses, weconstruct various measurements of migrant networks based on theshare of Swedish, other Scandinavian, and other foreign-born indi-viduals at both the county and neighborhood levels. To define theneighborhood leve

Breast cancer is the most common type of cancer in women worldwide. Triple-negative breast cancer (TNBC) is a subtype of breast cancer that lacks the expression of the oestrogen receptor, progesterone receptor, and amplification of HER2. This subtype is the most aggressive subtype and a heterogeneous subgroup of breast cancer, making up around 10-15% of the cases, often affecting younger patients

In this paper, we analyze the debate between the Modern Synthesis and the Extended Evolutionary Synthesis in light of the concept of incommensurability developed by Thomas Kuhn. In order to do so, first we briefly present both the Modern Synthesis and the Extended Evolutionary Synthesis. Then, we clarify the meaning and interpretations of incommensurability throughout Kuhn’s works, concluding that

Marine gastropods are characterized by an incredible variation in shell color. In this review, we aim to introduce researchers to previous studies of shell color polymorphism in this group of animals, trying to provide an overview of the topic and highlighting some potential avenues for future research. For this, we tackle the different aspects of shell color polymorphism in marine gastropods: its

The evolution and maintenance of color clines is a classic topic of research in evolutionary ecology. However, studies analyzing the temporal dynamics of such clines are much less frequent, due to the difficulty of obtaining reliable data about past color distributions along environmental gradients. In this article, we describe a case of decades-long temporal stability and directional change in a
