Minimax Linear Regulator Problems for Positive Systems : with applications to multi-agent synchronization

Exceptional are the instances where explicit solutions to optimal control problems are obtainable. Of particular interest are the explicit solutions derived for minimax problems, as they provide a framework for addressing challenges involving adversarial conditions and uncertainties. This thesis presents explicit solutions to a novel class of minimax optimal control problems for positive linear sy

Bio-Efficiency: On the valorisation of innovation in the bioeconomy

This article discusses a concept that institutions from the OECD to the EU increasingly employ in their response to the ecological crisis: The bioeconomy, wherein materials for economic activity would be bio-based and renewable. As a present-day project, the bioeconomy translates the critique of (fossil) carbon into patterns of (material) resource use and (economic) resource allocation, not least

The InterModel Vigorish (IMV) as a flexible and portable approach for quantifying predictive accuracy with binary outcomes

Understanding the “fit” of models designed to predict binary outcomes has been a longstanding problem across the social sciences. We propose a flexible, portable, and intuitive metric for quantifying the change in accuracy between two predictive systems in the case of a binary outcome: the InterModel Vigorish (IMV). The IMV is based on an analogy to weighted coins, well-characterized physical syst

Den vingklippta läraren: lärares erfarenheter av distansundervisning under coronapandemin

I denna artikel undersöks hur omställningen till distansundervisning i svenska gymnasieskolor i samband med coronapandemin påverkade lärare och förutsättningarna för deras pedagogiska uppdrag. Fokus i artikeln ligger på lärares upplevelser av sitt arbete och hur deras lärarvardag i flera avseenden kom att negeras under pandemin, vilket också kom att innebära att delvis omedvetna föreställningar om

String Intonation : Personal Expression and Pedagogical Challenges

In string performance of Western classical music, melodic intonation has generally been considered an expressive tool. However, empirical studies investigating performance intonation have often related intonation to different tuning systems, leaving music-contextual aspects of performance intonation rather unexplored. This work aimed to understand string musicians’ perceptual intonation preference

Amphibian Architecture: Dwelling in a Wetland

A case study house for a regenerative architecture. What would a regenerative architecture look like, in the context of a wetland landscape? With climate catastrophes becoming the new reality for an increasing amount of communities, floods among them, how would we live in a landscape, and with what materials would we build, in order to mitigate these issues? How do we live with a landscape, inste

Impact of probiotic dairy- and plant-based yogurt on gut health in healthy individuals

Kan växtbaserad yoghurt med tillsatta probiotiska bakterier gynna tarmfloran? Tarmfloran har kopplats till både hälsa och sjukdom, och genom att äta probiotiska bakterier hoppas man kunna gynna de goda bakterierna i tarmen, som får oss att må bättre. I den här undersökningen har en växtbaserad och en mjölkbaserad yoghurt med tillsatta probiotiska bakterier ätits i 4 veckor och deras effekt på taIn recent years, the development of meat-and dairy analogues has increased to meet demands from consumers, as well as serving as environmentally beneficial alternatives to meat and dairy. While traditional plant-based diets based on whole-foods have been shown to lead to beneficial health effects, the new analogues differ vastly from the ingredients of a whole foods, plant-based diet and the effec

Sediment Transport in the Piura River. Piura, Peru. An application with the HEC-RAS model.

This thesis is an investigation of sediment transport in the Piura River in Peru. Years of anthropogenic changes have redirected the river towards the south and have caused changes in the flow regimen (Alvarado Ancieta & Ettmer, 2007). It is suspected that the redirection towards the south has resulted in deposition of sediments which has reduced the capacity of the river in the lower reaches

Disentangling Regional Diversification : Identifying Theoretical and Empirical Challenges Through Complex Networks

Regional diversification has been positioned as a topic of great interest among researchers of economic geography, however, there remain some research gaps that must be attended to. Through the use of complex networks analysis from this literature in a period from 1975 to 2022, we identify some methodological and theoretical issues related to its measurement methods, the lack of an integrative fra

Effects of secular growth and mergers on the evolution of metallicity gradients and azimuthal variations in a Milky Way-like galaxy

We analyzed the evolution of the radial profiles and the azimuthal variations of the stellar metallicities from the VINTERGATAN simulation of a Milky Way-like galaxy. We find that negative gradients exist as soon as the disk settles at high redshift, and are maintained throughout the long-term evolution of the galaxy, including during major merger events. The inside-out growth of the disk and an o

A new specimen of Plesiopterys wildi reveals the diversification of cryptoclidian precursors and possible endemism within European Early Jurassic plesiosaur assemblages

A virtually complete and articulated plesiosaur skeleton (MH 7) is described from the Lower Jurassic (Toarcian) Posidonienschiefer Formation near Holzmaden in southern Germany. Plesiosaur remains are rare in this rock unit compared to those of other marine reptiles, such as ichthyosaurs and thalattosuchian crocodylomorphs. The new specimen offers an opportunity to assess the biodiversity of Early

ANN Based Fault Detection Classification in Power System Transmission line

The development of an artificial neural network to analyze power system faults is currently under way. However, the produced system is unsatisfactory because it is prone to failure and takes longer to detect faults. The ultimate goal of this project is to create an artificial neural network system that can identify and classify all forms of faults in power grid lines soon after they occur. In prin

Analysis of tool wear in micromilling Ti6Al4V and its impact on generated surface integrity

Tool wear is one of the dominant factors that impacts the surface integrity of machined materials. Understanding the impact of tool wear on surface integrity is crucial in micromilling, due to the size of the features being machined and the cutting tools. Therefore, this work aims to analyse the impact of tool wear on surface integrity during the micromilling of Ti6Al4V. In this context, microslot

Hence, improving energy efficiency has become an essential priority for the food sector. However, most food businesses have limited awareness of the recent technological advancements in real-time energy monitoring. Thus, the concept of “Inter

The digitisation of food manufacturing to reduce waste : case study of a ready meal factory

Generation of food waste (FW) continues to be a global challenge and high on the political agenda. One of the main reasons for its generation is the absence of detailed data on the amount, timing and reasons for created waste. This paper discusses the design, the application and investigates the Internet of Things (IoT) based FW monitoring system to capture waste data during manufacturing in real-

Energy Efficiency Potential of Second Homes Heated by Direct Electric Heating Located in Four Regions in Sweden

EU countries have committed to taking national measures to reduce the average energy use of residential buildings by 16% by 2030 and 20–22% by 2035. Each country has decided how to achieve this and which buildings to focus on. However, certain categories of residential buildings, including historical buildings but also second homes, may be exempt from these obligations. In Sweden, second homes con
