Heat load forecasts are crucial for energy operators in order to optimize the energy production at district heating plants for the coming hours. Furthermore, forecasts of heat load are needed for optimized control of the district heating network since a lower temperature reduces the heat loss, but the required heat supply at the end-users puts a lower limit on the temperature level. Consequently,
Optical and laser diagnostics is a field where optical techniques are developed that offer remote, non-intrusive measurements in order to characterise a system. Imaging is a big part of this field and the versatility it offers makes it a great tool in the hands of researchers and in practical applications. In this thesis, multiple applications of imaging are presented, together with possible data
Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mechanical rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione
Renovation of water and central heating pipelines is a very costly and time-consuming process, so a way to prioritize the limited resources between different parts of the systems is very important. The risk for corrosion damage can be assessed from the resistivity of the ground, due to the processes facilitating the metal oxidation also affecting the resistivity, but galvanic resistivity mapping i
Background: The autoimmune destruction of beta cells, resulting in clinical type 1 diabetes, may start early in life and last for several months or years. During this period of time, we have an opportunity to try to prevent or delay further beta-cell destruction and clinical onset of type 1 diabetes. Objectives: Ongoing prediction and prevention studies in Skåne, Sweden are described. Methods: Dur
Green building rating systems are voluntary tools intended to promote sustainable building process through approaching several environmental issues that include sustainable design parameters related to the construction site and others related to its surrounding context. Decision making software support tools and methods are needed to guide practitioners on minimizing building’s environmental impac
Soot emissions from diesel engines are the net result of two competing processes: soot formation and soot oxidation. Previous studies have shown poor correlation between soot formation rates and the soot emissions. This article presents a systematic study of a number of parameters affecting soot oxidation rate and how it correlates with the soot emissions. An optical heavy-duty engine is used in c
Hydrogen refueling station is one of the most important parts for the hydrogen energy utilization. In this paper, a novel high multi-stage pressure reducing valve (HMSPRV) is proposed, which can be used for hydrogen stable decompression in hydrogen refueling station. In HMSPRV, the inner and outer porous shrouded valve core is used to replace piston valve core to achieve the first-stage throttling
Popular Abstract in Swedish Denna doktorsavhandling presenterar resultaten från ett forskningsprojekt inriktat mot arkitektonisk utformning i det industriella byggandet. Arbetet har inledningsvis fram till licentiat bedrivits inom ramen för ett nationellt forskningsprogram inriktat mot industriellt träbyggande, Lean Wood Engineering. Ansatsen i detta forskningsarbete har emellertid varit att förutThe thesis presents the results from a research project targeting architectural design and house-building in a setting of industrialized design process and product platforms. During the early stages of a traditional design process, architects manage a degree of problem complexity, besides technical aspects, also includes user function, material, environment, aesthetics etc. As a result of the des
uses a microporous membrane operated in cross-flow. The continuous phase is pumped along the membrane and sweeps away dispersed phase droplets forming from pore openings as shown in Figure 1. The key feature of the membrane emulsification process, which sets it apart from conventional emulsification technologies, is that the size distribution of the resulting droplets is primarily governed by the
Popular Abstract in Swedish Modellering och simulering är etablerade tekniker för att lösa designproblem inom många olika ingenjörsdiscipliner idag. Dedicerade språk, såsom Modelica, och effektiva mjukvaror finns också tillgängliga. I denna avhandling presenteras en språklig utvidgning av Modelica, Optimica, som är avsedd för formulering av dynamiska optimeringsproblem. För att demonstrera användnModeling and simulation are established techniques for solving design problems in a wide range of engineering disciplines today. Dedicated computer languages, such as Modelica, and efficient software tools are available. In this thesis, an extension of Modelica, Optimica, targeted at dynamic optimization of Modelica models is proposed. In order to demonstrate the Optimica extension, supporting sof
The purpose is to explain the value of utilising tracking data for material flow control purposes in different supply chain areas. The research methodology is based on a literature review and a case study of a distribution system originating from an international paper manufacturer. The distribution system in the analysis started RFID technology adoption more than ten years ago and has developed
Abstract What are the pedagogical impacts of internationalisation on the development of higher education in Europe? How can we proceed in this process and take a pedagogical stance on the issue? This theoretical paper is partly based on a series of empirical studies conducted by the author, investigating students’ and teachers’ experiences and understanding of an internationalised educational cont
In 2008-2009 Lund University, Sweden, took part in two European benchmarking projects on eLearning, E-xcellence+ (EADTU) and Benchmarking eLearning exercise2009 (ESMU) as part of the University’s policy for quality assurance and quality enhancement of education. Among the aims were · to adopt, as the first Swedish university, a benchmarking process according to quality criteria of eLearning formul
The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. Secondly, innovative technologies must be developed to overcome the intrinsic low degradation rates of hardly-degradable pollutants in order to allow short treatm
The definition of Validation and Verification (V&V) tests for analysing evacuation model capabilities is the object of a large debate among researchers given the lack of an international standard. Four main types of tests have been reported in the literature, 1) component testing, 2) functional verification, 3) qualitative verification and 4) quantitative validation. An important issue relates
SETI, our hopes or fears of a future contact with ETI, is a modern expression of an unending human obsession with the rise and fall of civilizations. People across the globe from our earliest sources to our contemporary culture have tried to understand the beginning and end of history, the creation and the doom. Factor L of the Drake Equation could in other words be understood in a longer historic
In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic aci
