A map is a combinatorial presentation of map objects and labels providing users with sufficient and useful information. Text placement is the most time-consuming and cumbersome work in a map production process, and many methods have been proposed to automate this process. However, text placement evaluation lacks exploration, especially when artificial intelligence (AI) methods are experiencing pro
The general Z2-violating two-Higgs-doublet model (2HDM) is analysed as an explanation for the discrepancy between Standard Model predictions and experimental measurements of the muon anomalous magnetic dipole moment ∆aµ, with the condition that it does not provide an electron electric dipole moment |eEDM| larger than experimental bounds. Several point studies of individual 2HDM parameter space poi
Recurrent neural networks (RNNs) have become a dominating player for processing of sequential data such as speech and audio. The reason for this, is the high accuracy that can be achieved with the more complex variants, such as the gated recurrent unit (GRU). This makes them very attractive in speech recognition systems for digital assistance and voice control applications. However, a high power c
While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. The chemical processing limitations for perovskites are laid out and common
Thin-Film Transistor (TFT) technology refers to process and manufacture transistors, circuits, Integrated circuits (ICs) using thin-film organic or metal-oxide semiconductors on different substrates, such as flexible plastic foils and rigid glass substrates. TFT technology is attractive and used for applications requiring flexible, ultrathin ICs to enable seamless integration into devices. TFT t
Denna studie berör gästnöjdhet och återkoppling vilka är viktiga aspekter när man arbetar med kunder. Speciellt inom hotellindustrin är detta viktigt då bra service handlar om att känna sin gäst. Hotellen vill veta alla bekymmer eller funderingar som gästen har medan de är kvar på hotellet för att kunna kompensera innan de lämnar. För att möjliggöra detta behöver hotellen ha bättre kommunikation mThis study concerns guest satisfaction and feedback which are important aspects when working with customers. In the hotel industry this is especially important since good service is about knowing your guest. The hotels want to be aware of any concern while the guest is still at the hotel to be able to compensate before they leave. In order to do so, the hotels need a better communication with thei
In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. The main design principle behind NR is to allow enoug
An integrated biological process for the production of hydrogen based on thermophilic and photo-heterotrophic fermentation was evaluated from a technical and economic standpoint. Besides the two fermentation steps the process also includes pretreatment of the raw material (potato steam peels) and purification of hydrogen using amine absorption. The study aimed neither at determining the absolute c
The new clusters [H(4) Ru(4) (CO)(10) (μ-1,2-P-P)], [H(4) Ru(4) (CO)(10) (1,1-P-P)] and [H(4) Ru(4) (CO)(11) (P-P)] (P-P=chiral diphosphine of the ferrocene-based Josiphos or Walphos ligand families) have been synthesised and characterised. The crystal and molecular structures of eleven clusters reveal that the coordination modes of the diphosphine in the [H(4) Ru(4) (CO)(10) (μ-1,2-P-P)] clusters
This paper describes the performance evaluation of new Delta E detectors to be used as pre-cell hit detectors in living cell irradiation experiments at the Lund Ion Beam Analysis facility (LIBAF). Using these detectors with a thickness down to 4.15 mu m fabricated at Lund University, an experiment was setup in which Delta E-detectors were used together with a stop E-detector in a telescope system
Non-alcoholic fatty liver disease (NAFLD), obesity and type 2 diabetes(T2D) are strongly associated and today their prevalence reaches epidemic proportions. NAFLD has a multi-factorial aetiology, both genetic and environmental factors are equally important. The aim of this thesis was to investigate genetic factors associating with NAFLD and circulating triglyceride (TG) levels in overweight or obe
Parkinson´s disease (PD) is a neurodegenerative disorder characterized by the typical motor symptoms, akinesia/bradykinesia, rigidity and resting tremor. These symptoms are caused by a deficiency of dopamine (DA) in the brain, which depends on degeneration of DA neurons in the substantia nigra. The most effective treatment for PD is the DA precursor, L-DOPA. Unfortunately, within a few years, L-DO
In this paper, we propose a design framework for distributed embedded control systems that ensures reliable execution and high quality of control even if some computation nodes fail. When a node fails, the configuration of the underlying distributed system changes and the system must adapt to this new situation by activating tasks at operational nodes. The task mapping as well as schedules and con
Hip fractures are devastating for the individual and a substantial economic burden for society. The treatment for displaced femoral neck fracture is a choice between internal fixation, total hip arthroplasty and hemiarthroplasty. As a result of several randomized trials, the treatment has shifted in Sweden from mostly internal fixation towards arthroplasties. There have been concerns about long-te
We have developed a method to estimate free energies of reactions in proteins, called QM/MM-PBSA. It estimates the internal energy of the reactive site by quantum mechanical (QM) calculations, whereas bonded, electrostatic, and van der Waals interactions with the surrounding protein are calculated at the molecular mechanics (MM) level. The electrostatic part of the solvation energy of the reactant
Abstract in UndeterminedThe MAX IV facility presently under construction will include two storage rings for the production of synchrotron radiation. Both rings will be operated at a constant 500 mA of stored current with top-up shots supplied by the MAX IV linac acting as a full-energy injector. Until recently, injection into both storage rings was designed using a conventional approach: a closed
Multi-antenna enabled terminal devices are required to comply with the standards for limiting human exposure to electric fields. However, when compared to traditional single-antenna terminals, a comprehensive evaluation of specific absorption rate (SAR) for multi-antenna terminals is impractical. This is because both the power allocation and phase of the electric fields from different antennas are
In object-oriented programs, the relationship of an object to many objects is usually implemented using indirection through a collection. This is in contrast to a relationship to one object, which is usually implemented directly. However, using collections for relationships to many objects does not only mean that accessing the related objects always requires accessing the collection first, it also
