This thesis aims to develop and evaluate a fast design and optimisation workflow for corrugated tubes used in tubular heat exchangers by combining computational fluid dynamics (CFD) simulations and machine learning. A steady-state Reynolds-averaged Navier-Stokes (RANS) model was established to simplify the simulation process and reduce computational time. Based on the selected CFD setup, a CFD dat
This thesis explores how performance artists with side jobs create and experience the value of work in relation to neoliberal capitalism, by exploring the continuation of life projects not in line with hegemonic values and conventional work-life boundaries. Through interviews with 8 key informants, and participant observation in work contexts and at a cultural hub for creatives, the study recognis
This research explores the state of sustainability and the implementation of sustainable practices in Albania and Greece. Specifically, it examines how municipalities have utilized EU green funding and how they raise awareness about sustainability within their local communities. Qualitative interviews were conducted with city officials from the municipalities of Lushnje and Vlora in Albania, as we
This paper describes a co-design based approach for automatic generation of application specific systems, suitable for FPGA-centric embedded applications. The approach augments a processor core with hardware accelerators extracted automatically from a high-level specification (Java) of the application, to obtain a custom system, optimised for the target application. We advocate herein the use of a
Popular Abstract in Swedish Trögers bas är en molekyl som syntetiserades första gången 1887. Molekylen är stel, C2-symmetrisk och böjd i ca 90° vinkel och den formar en kiral hydrofob ficka. I denna avhandling beskrivs syntesen av nya analoger av Trögers bas. Aniliner, substituerade med halider i 2- och 3-position, har för första gången kondenserats till analoger av Trögers bas. Dessutom har det vTröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. It has also been shown that anilines without substituents in para-po
Are there special ways of exerting influence for small states in a complex multi-actor governance system such as the EU? Intergovernmental theories of European integration emphasize great power nota bene the Franco-German axis, but other observers suggest that smaller member states may actually use the EU institutions to their advantage. Based on literature about small states in international rela
Development of artificial neural network (ANN) models using real plant data for the prediction of fresh steam properties from a brown coal-fired boiler of a Slovenian power plant is reported. Input parameters for this prediction were selected from a large number of available parameters. Initial selection was made on a basis of expert knowledge and previous experience. However, the final set of inp
This report presents a large number of optimal PI and PID parameters for a batch of 134 benchmark process models representative for the process industry. This information can e.g. be used as a reference for other controller design methods. The optimal parameters have been derived using the MATLAB®-based software called SWORD, which determines the PI or PID controller that gives the best load distu
The purpose of building classification systems is to provide the sector with agreed and standardised ter¬minology and semantics, e.g. in systems for technical specification, cost calculation, and exchange of information. There is a growing need to use classification systems in a BIM context. In inter¬¬national construction projects and international construction product trade there is a need both
Shadows heighten realism and provide important visual cues about the spatial relationships between objects. But integration of robust shadow shadowing techniques in real-time rendering is not an easy task. In this course on how shadows are incorporated in real-time rendering, attendees learn basic shadowing techniques and more advanced techniques that exploit new features of graphics hardware.The
The finite element method is applied to solve coupled steady-state fluid flow and heat transfer problems in insulated pipes of district heating networks. The main advantage of the finite element method involved here is the standard discretization and solution technique for both coupling of temperature-dependent physical properties in the thermo-hydraulic flow and for description of the multilayere
A multicolor fluorescence imaging system applied to medical diagnostics is described. The system presented simultaneously records four fluorescence images in different wavelength bands, permitting low-resolution spectroscopy imaging. An arithmetic function image of the four spectral images is constructed by a pixel-to-pixel calculation and is presented on a monitor in false-color coding. A sensiti
This paper presents an efficient programmable engine that supports diverse interpolation algorithm in different video coding standards, such as H.264/AVC, and the Chinese national standard, AVS. It is a VLIW(very long instruction word) and SIMD(single instruction multiple data) hybrid architecture which could issue four ALU operations and one memory reference or a branch operation in every clock c
Nocturnal animals relying on vision typically have eyes that are optically and morphologically adapted for both increased sensitivity and greater information capacity in dim light [1]. Here, we investigate whether adaptations for increased sensitivity also are found in their photoreceptors by using closely related and fast-flying nocturnal and diurnal bees as model animals. The nocturnal bee Megal
This paper gives a brief summary of computational methods in heat transfer equipment, such as CFD (computational fluid dynamics) methods for thermal problems (computational heat transfer), and turbulence modeling for single-phase applications in the design, research and development of heat exchangers. Details of the finite volume method and their extension to arbitrary geometries are presented. An
