This master thesis was a project in cooperation with Höganäs AB. The aim was to increase the apparent density (AD) of two biomass chars, by three different agglomeration methods. The reason for the investigation is that biomass char could be used as a reducing agent in the sponge iron process at Höganäs AB. The goal was to exchange anthracite in the reduction mixture to agglomerated biomass char.
Many natural resources lead economies experience worse economic performance than their exports lead counterparts. This phenomenon is known as the Resource Curse, and many resource abundant countries face it. This study is aimed to critically assess existing Resource Curse theory by comparing two seemingly different cases Kazakhstan and Norway. Based on the Resource Curse theory hypothesis suggests
In this thesis, a stronger support for Model Predictive Control (MPC) in JModelica.org has been implemented. JModelica.org is an open-source software for simulation and optimization of systems described by Modelica models. MPC is an optimization-based control strategy where one formulates an Optimal Control Problem (OCP) to describe the aim of the controller. At discrete time points the state of t
The Sjölunda wastewater treatment plant faces the challenge of tougher demands for the quality of the water leaving the plant and entering the Öresund strait between Denmark and Sweden. At the same time, the population of Malmö with neighbourhood is growing rapidly, which means an increase in the loading on the plant. The residence time for the active microbes, the “sludge”, in the first biologicaAlthough 100 years old, the activated sludge system remains inevitable for modern wastewater treatment. Advancements within the development of mainstream nitrogen removal techniques based on anaerobic ammonium-oxidising bacteria have renewed the interest in traditional, high-loaded activated sludge systems for COD removal only. In order for activated sludge plants to be efficient in terms of energ
Attributional styles have been paid little attention in the organizational context and previous research has mostly focused on the consequences of attributional styles, such as how attributional styles influence work behaviors. Attributional styles development in work settings has thereby been paid little attention, as for example, how individuals’ way of attributing in an organization can be shap
Most migratory bird species divide their migration in stages of flight and stopovers. They use these stopovers to refuel the energy reserves needed to face their long migration journeys. These stopovers are an important element to determine the overall migration speed. Time spent on migration and arrival date to the wintering grounds have been demonstrated to have a large effects the following bre
Nowadays society is becoming more aware of the fact that energy use has a negative environmental impact, contributing to fossil fuels depletion and global warming increase. Therefore, the Swedish Parliament has adopted the The European Comission’s 20-20-20 goals, climate and energy policy targets that shall be achieved by 2020, referring to 20% reduction of CO2 emissions, 20% increase in energy ef
Bakgrund: Att konsumera resor har blivit ett allt vanligare sätt för individer att skapa och förmedla sin identitet. Hur och var individer reser påverkar inte bara hur de ser på sig själva, utan det skapar även en uppfattning av hur omgivningen uppfattar dem. Resultatet har blivit att individer inte väljer resmål utifrån sina önskemål, utan utifrån vilken bild de vill förmedla av sig själva. Efter
The field of disease proteomics is lacking techniques capable of analysing complex samples with high sensitivity and selectivity. A new MIcroArrays in Solution (MIAS) technology is being developed to addres the technological issues of the current established methods, such as antibody microarrays, 2DE and MS used for protein expression profiling. MIAS technology is based on DNA barcode labeled scFv
Many surveillance applications could benefit from the use of stereo cam- eras for depth perception. While state-of-the-art methods provide high quality scene depth information, many of the methods are very time consuming and not suitable for real-time usage in limited embedded systems. This study was conducted to examine stereo correlation methods to find a suitable algorithm for real-time or near
Nanocarriers and nanoreactors are often derived from viral capsids. The capsid of HBV is a particularly attractive self-assembling model, fit for conversion into protein carrier. In this thesis modified HBV capsid is expressed in E.coli and purified by size exclusion chromatography. Nanocarrier system is based on principle of specific binding between the modified capsid building block and protein
Conventional photovoltaic solar tracking is commonly done by aligning the surface normal of a PV module with the direction from which direct solar irradiation is coming from. While this tracking design has proven to perform well in sunny climates, solar tracking is altogether less common in northern climates where the direct solar irradiance is weaker. In this study a radiative transfer model is u
Uppsatsen tar avstamp i SOM-insitutets mätning från 2014 som visade att en majoritet av de tillfrågade ansåg att svenska medier inte berättar sanningen om samhällsproblem kopplade till frågor som rör migration- och flyktingpolitik. Samtidigt som med misstroendet mot medierna breder ut sig fortsätter digitaliseringen av medielandskapet vilket leder till en allt mer diversifierad nyhetskonsumtion. DThe essay builds on a public opinion poll from 2014 indicating that a majority of the Swedish citizens believe that mainstream media are hiding “the truth” about social problems related to issues of migration and refugee policy. The outspread distrust of mainstream media takes place during a time of continuing digitalization of the media landscape, which has led to increasingly diversified news co
Påverkar höjd människors benägenhet att utrymma via sky bridges? Försök i virtuell och fysisk miljö En sky bridge är en allt vanligare lösning för att underlätta förflyttning mellan höga byggnader. Sky bridges kan också användas för att förbättra utrymningssituationen i höga byggnader. För att undersöka hur personer uppfattar utrymning från höga byggnader via sky bridges kan verktyget Virtual ReThis report is a master thesis at Lund University. The aim of this report is to examine how height effects peoples willingness to evacuate from a building using a sky bridge. The study also aims to investigate if Virtual Reality and more specifically Oculus Rift is a useful tool in research regarding evacuation at high elevation. This was investigated by conducting experiments in Virtual Reality.
Rapporten beskriver utvecklingsarbetet av funktionen att manövrera en ramp som satt placerad på ett stridsfordon. Rampen satt monterad på den bakre gaveln på stridsfordonet CV90 som tillverkades av BAE Systems Hägglunds i Örnsköldsvik. Där har examensarbetet genomförts under våren 2015. I den bakre delen utav stridsfordonet så fanns det ett utrymme för att transportera åtta soldater. De tog sig i
Plattektoniska processer formar idag vår jord genom vulkanism, relaterad till divergenta och konvergenta plattrörelser. Hur länge har plattektoniken existerat och hur kan vi spåra plattektoniska processer bakåt i tiden? Detta kandidatarbete behandlar och diskuterar olika typer av plattektoniska indikatorer, hur de går att koppla till moderna processer och hur tillförlitliga de anses vara. Moderna Plate tectonic processes shapes our earth due to volcanism, related to divergent and convergent plate motions. When did plate tectonics begin and how can we trace plate tectonic processes throughout time? This Bachelor thesis address and discuss different plate tectonic indicators and their reliability. Modern analogues are indicators that can be linked to modern plate tectonic processes, and does
