The increased impact from fluctuating energy sources like wind and photovoltaics significantly affects the operational regime of conventional power plants. In the near future, even former base load power plants such as the large-scale lignite plants in Germany will need to start and shut down to balance the electricity system. As frequent starts were not in the focus of optimisation in the past, a
Remote sensing is a key tool for precision agriculture applications as it is capable of capturing spatial and temporal variations in crop status. However, satellites often have an inadequate spatial resolution for precision agriculture applications. High-resolution Unmanned Aerial Vehicles (UAV) imagery can be obtained at flexible dates, but operational costs may limit the collection frequency. Th
In the emerging field of Internet of Things (IoT), where computerized devices are combined in creative new ways, there is a need to create Graphical User Interfaces (GUIs) for the systems being built, e.g. in the form of Android “apps”. This is generally a complicated, time consuming task. We report from a controlled experiment that evaluates a new approach for building GUIs that aims to make it e
This chapter discusses Bergman’s potential worth in the commercial film market on the basis of the director’s own correspondence with potential co-producers and international distributors of his films. The author first studies Bergman’s ample correspondence with Carl Anders Dymling, the powerful head of the Swedish production company Svensk Filmindustri between 1942 and 1961; most of Bergman’s ear
The direct reaction between carbohydrates and CO2 has recently attracted attention in the context of cellulose dissolution and derivatization as well as carbon capture applications. We have directly demonstrated the formation of cellulose carbonate upon the introduction of CO2 into a non-aqueous cellulose solution by nuclear magnetic resonance spectroscopy. Comparison of the observed spectra with
Low-Power Wide-Area Networks operating in the unlicensed bands are being deployed to connect a rapidly growing number of Internet-of-Things devices. While the unlicensed sub-GHz band offers favorable propagation for long-range connections, measurements show that the energy consumption of the nodes is still mostly dominated by the wireless transmission affecting their autonomy. We investigate the p
Motivated by a need to characterize transient behaviors in large network systems in terms of relevant signal norms and worst-case input scenarios, we propose a novel approach based on existing theory for matrix pseudospectra. We extend pseudospectral theorems, pertaining to matrix exponentials, to an input-output setting, where matrix exponentials are pre- and post-multiplied by input and output m
In this paper, we present a system for extracting tabular information from loosely structured handwritten documents. The system consists of three parts, (i) a u-net like CNN-based method for text detection and segmentation, (ii) a new attention-based method for simultaneous text recognition and classification of word-parts, and (iii) a method for matching the word parts into a tabular structure fo
In this paper we address absolute camera pose estimation. An efficient (and standard) way to solve this problem, is to use sparse keypoint correspondences. In many cases point features are not available, or are unstable over time and viewing conditions. We propose a framework based on silhouettes of quadric surfaces, with special emphasis on cylinders. We provide mathematical analysis of the probl
Byzantium has played only a minor role, if any at all, in the Western appropriation of knowledge on Islam. One exception to this is the Panoplia dogmatike by Eustathios Zigabenos, active under and working on the commission of the Byzantine emperor Alexios I Komnenos (r. 1081-1118). The Panoplia dogmatike ('Dogmatic Armoury') was a most imperial text, designed to support the emperor's fight against
Antennas are one of the key components that empower a new generation of wireless technologies, such as 5G and new radar systems. It has been shown that antenna design strategies based on modal theories represent a powerful systematic approach to design practical antenna systems with high performance. In this thesis, several innovative multi-antenna systems are proposed for wireless applications in
This paper presents a neural network based semantic plane detection method utilizing polygon representations. The method can for example be used to solve room layout estimations tasks and is built on, combines and further develops several different modules from previous research. The network takes an RGB image and estimates a wireframe as well as a feature space using an hourglass backbone. From t
Impactful applications such as materials discovery, hardware design, neural architecture search, or portfolio optimization require optimizing high-dimensional black-box functions with mixed and combinatorial input spaces. While Bayesian optimization has recently made significant progress in solving such problems, an in-depth analysis reveals that the current state-of-the-art methods are not reliab
Anticipation entails contemplating the beneficial and harmful impacts of scientific and technological progress. Anticipation has a long history in science, technology, and innovation policy partly due to future impacts of scientific progress being inescapable. The link between anticipation, an undertheorized concept, and human rights law is yet to be fully explored. This paper links anticipation t
Ensuring functional safety is crucial for the deployment of autonomous systems in real-life dynamic environments, as they must operate reliably and safely among humans. However, existing safety systems are designed with a closed-world assumption and can over-constrain the system by shutting down the robot at every safety violation, limiting the robot’s ability to complete its tasks.

Maritima avgränsningstvister kräver uppmärksamhet- och hänsynstagande till, i varje enskilt fall, unika omständigheter. För att möta dessa krav krävs precisa och rättvisa bedömningar av ICJ för att upprätthålla rättssäkerheten. Resultatet av en ny havsgräns, vare sig det gäller uppdelning av naturresurser eller kust-sträcka, kan ha enorma effekter på de påverkade staterna. Det legala ramverket ICJMaritime delimitation disputes demand attention to and evaluation of a substantial amount of, in every different case, unique circumstances. Meeting this demand calls for precise and equitable judgements by the ICJ to uphold legal order. The results from a new maritime border being drawn, whether it be partitioning of natural resources or a certain coastal projection, can have tremendous effects o
