Modelica allows systems to be described with reuseable components and with a high precision. To be able to use such complex models efficiently, high demands are set on tools that allow the user to extract the information needed from the models in a straight-forward manner. For this purpose, design-of-experiments techniques can be used to systematically analyze the complex models.In this paper, it
In Western European choral traditions, the ambition of most choirs is to attain an equalized blend of sound and to perform well together with regard to timing and intonation. In order to be able to synchronize this the choir members need to cooperate musically and listen to each other. Choirs often have close bonds, both socially and with regard to their common musical aim to perform well in conce
The short-time iterative adaptive approach is a spectral estimation alternative to the short-time Fourier transform for non-stationary vibration analysis. This technique offers a reduction in leakage effects and a higher resolution in exchange for a higher computational complexity. The short-time iterative adaptive approach can be summarized as a high-resolution data-dependent approach which has b
Industrial symbiosis, a concept derived from industrial ecology, emphasizes the collaborative and synergic production among industries. The particular focus is on cyclical flows of resources (material, energy, water, and/or by-products), in order to minimize impacts on the environment. In this way, an industry could reuse the discarded resources of another industry as an input to production. Essen
Datasets are growing in size and complexity, especially with respect to the number of features of the problems that we study, which now often number in the millions. This has lead to a surge in interest for sparse regression models, which help make sense of these datasets by modeling them efficiently whilst still retaining a notion of explainability. Because these datasets are so large, however, t
There is a lack of knowledge among food manufacturers about adopting the Internet of Things (IoT)-based water monitoring system and its ability to support water minimisation activities. It is therefore necessary to investigate the applicability of IoT-based real-time water monitoring systems in a real food manufacturing environment to pursue water-saving opportunities accordingly. This article aim
The aim of this study has been to investigate the self-diffusion behaviour in polymer solutions and in surfactant solutions using the pulsed field gradient (PFG) NMR technique. The NMR self-diffusion experiment was shown to provide detailed information in complex surfactant mixtures. In particular, the microemulsion phase and the hexagonal phase of Didodecyldimethylammoniumsulphate (DDAS) formed
This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. It is a narrow band filter designed for the American digital mobile telephone system accordin
Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con
Modelling is a fairly mature technology that is already being adopted by industry. Unfortunately the tools for supporting Model-Driven Engineering are not at the same level of maturity. In particular merge tools that are an important help for collaboration lack a lot to be desired in providing the support that is needed on industrial projects. Current model merge tools and research approaches focu
A common floor construction in a lightweight building system is using chipboard plates attached to wooden beams using screws and glue. One drawback with such a system is the propagation of vibrations stemming either from harmonic (washing machines, dishwashers, HiFi-systems) especially at low frequencies and/or transient (Human walking, dropped items, slamming doors) excitations. In order to accur
Arsenic contamination of drinking water is a result of natural and/or anthropogenic activities, causing undesirable detrimental effects on the environment and the human health. Herein, an integrated process based on Membrane Distillation (MD), photocatalysis and Polymer-enhanced Ultrafiltration (PEUF) was developed for an effective remediation of arsenic (As). This approach, whose effectiveness wa
Inom svensk forskning om läsundervisning har det framhållits att elever redan på mellanstadiet (åk 4-6) behöver utveckla litterär kompetens och få vägledning i hur de kan angripa och bearbeta en text för att utveckla fördjupad läsförståelse. Syftet med föreliggande artikel är att ge ett kunskapsbidrag beträffande hur undervisning som syftar till att utveckla förmågan att dra slutsatser om en skönl
The creation of prototypes for the design of new products is a fundamental activity in the metal-mechanic sector that contributes to Bolivia's socioeconomic development. The existence of a multitude of factors that positively or negatively affect the prototype, are encompassed in two approaches: i) prototyping engineering and ii) prototyping management. Research for the design of prototypes suitab
In this study, a physico-chemical analysis of the Rocha River was performed during the beginning of the rainy season 2018 in order to examine the current state of the water quality in the river at six different locations. The river, located in the Cochabamba department, Bolivia, was examined from upstream in Sacaba to downstream in Sipe Sipe. An additional aim was to determine social and environme
Lagen (1982:80) om anställningsskydd, är den lag som torde vara av störst betydelse när det kommer till anställningar. Den reglerar bl.a hur en anställning ingås, vilka anställningsformer som finns och regler kring hur en anställning upphör. Från lagens tillämpningsområde undantas bl.a. personer med en företagsledande ställning och arbetsgivarens familjemedlemmar. Undantagen har motiverats med attThe Swedish law regarding the protection of employment, LAS (1982:80) is probably the most important law when it comes to employments. The law regulates how an employment is concluded, which kind of employment one may have and the rules on how employment is terminated. Persons with management positions and family members of the employer are excluded from the scope of the law. The reason that these
For many years, critics of the European Union copyright framework have raised concerns about the lack of legal recognition of exceptions and limitations to copyright-protected works and other protected subject matter, and argued that the European Union copyright framework favours the protection of intellectual property over fundamental rights. The debate about this imbalance reached new heights wh
I denna uppsats observeras först den historiska bakgrunden till konflikten kring visstidsanställningar och rättsutvecklingens stora drag med särskilt fokus på anställningsformerna. Efter detta lyfts den fackliga kritiken mot visstidsanställningar i allmänhet och behovsanställningar i synnerhet. Kritiken påpekar att anställningssäkerheten minskas av visstidsanställningar. Efter det radas metod, syfThis paper first observes the historical background of the conflict surrounding fixed-term employment contracts and the legal history of the matter, focusing especially on the formal types of employment. Following that the critisism leveled at fixed-term contracts by trade unions is noted. The criticism concerns fixed-term contracts in general, and zero-hour contracts in particular. It is pointed
