Popular Abstract in Swedish Vetskap om strömning av vätskor och gaser är viktigt i dagens samhälle, vilket inkluderar transport i rör, förbränning, och flödesinducerade vibrationer. På grund av sin flyktiga form är möjligheten att kontrollera flöden i diverse applikationer begränsad. Strömning kan vara väldigt svårt att beskriva och kategorisera, speciellt då höga hastigheter är inblandade. HastigThis thesis presents the utilization of two different decomposition techniques, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), for enhanced understanding of flow structures and their stability. The advantages of these techniques are shown for a range of flow situations, most of which are turbulent. It is shown that by these methods additional insight into complex flow

The aim of the European project MASTER (MAnaging Speeds of Traffic on European Roads) is to produce information that can be cited in the preparation of national and EU decisions concerning speed management and standards for speed control equipment. For this purpose, the project seeks answers to three key questions:1) What are acceptable ranges of speeds?2) What are the key factors influencing dri

Amelogenin is an extracellular matrix protein involved in formation of enamel during early tooth development. By interacting with the forming enamel crystallites amelogenin affects their growth, so that highly elongated hydroxyapatite crystals are formed. Early during the enamel formation amelogenin is proteolytically processed, which is essential for correct enamel formation. However, the exact m

During the last three decades, a vast variety of methods to numerically solve ordinary differential equations (ODEs) and differential algebraic equations (DAEs) has been developed and investigated. Few of them met industrial standards and even less are available within industrial multibody simulation software. Multibody Systems (MBS) offer a challenging class [5] of applications for these methods,

Value configurations, originally in the form of the value chain, serve as descriptions of how value is created. They focus on the internal activity character in interaction with the environment and can be seen as the essence of business models. Here, the role of standardization in association with value configurations is clarified through the introduction of a framework outlining how process and o

Different optical methods for tumour detection have been studied. Interference between photon density waves has been examined with the aim of investigating the potential of this technique for optical transillumination diagnostics. Simulations and experiments have been performed in the time domain on realistic tissue phantoms containing bodies with differing optical properties. The recorded data we

Convolutional codes are defined to be equivalent if their code symbols differ only in how they are ordered and two generator matrices are defined to be weakly equivalent (WE) if they encode equivalent convolutional codes. It is shown that tailbiting convolutional codes encoded by WE minimal-basic generator matrices have the same spectra. Shearer and McEliece showed that MacWilliams identity does n
