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.

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
No country has yet achieved full gender equality and one of the reasons is the stereotypical attitudes towards characteristics and roles of men and women. International community has acknowledged that gender stereotypes are an obstacle to full realisation of human rights of women and men and the obligation to tackle those has been included in the Convention on Elimination of all Forms of Discrimin
This study contributes to fill the gap in the existing community health worker literature by offering a more nuanced perspective on performance motivation of healthcare workers from rural South Africa. Specifically, it focuses on the various work incentives and perceived organization support that shape work performance of healthcare workers and, therefore, organizational effectiveness. By followin
Cooperative and reciprocal practices within agriculture have been widely discussed as important strategies in order to reduce risks and costs of labour and capital acquisition. Within the Andes reciprocal norms appear to be particularly institutionalized due to their historical rootedness in Andean culture. With the present case study I sought to examine reciprocal exchange practices in agricultur
Biotechnology has been regarded as the problem child of modern Patent Law for a long time. The legislation concerning biotechnology is in constant fluctuation, changing as the case law constantly develops. This leads up to uncertainty regarding what is to be considered as patentable, and what is not. Even today, no stable solution has been found. Furthermore, ethical concerns are given a place w
This thesis included an energy and moisture analysis of an existing 70’s villa. This villa is located in Bjärred, Lomma municipality. The Reference house is a single storey with a foundation of concrete slab and is part of a community association of 20 similar villas’. The work included different types of analyzes and measurements of the villa. A literature study was done to get a better view of t
Med anledning av offentlig upphandling kan det emellanåt förekomma att leverantören på olika sätt vilseleder myndigheten för att på oriktig grund antingen teckna ramavtal med myndigheten eller av myndigheten erhålla ett upphandlingskontrakt. Problematiken med olika former av vilseledande får antas vara större vid offentlig upphandling än vid vanliga B2B-relationer på grund av det strikta regelverkOccasionally when a contracting authority is about to award a public contract or conclude a framework agreement with a supplier, the supplier somehow misleads the contracting authority in order to receive the public contract or the framework agreement. Due to the rigorous regulatory system that distinguish public procurement one can expect the misleading to be a problem of greater importance than
Det internationella immaterialrättsliga rättssystemet har etablerats på grundsatsen att immaterialrättigheter är territoriella och därmed begränsade sett till innehåll och omfång till respektive skyddsland. Den territoriella begränsningen bekräftas av bl.a. Bernkonventionen och Pariskonventionen på området och är väl förankrad i svensk rätt, dock väldigt sällan i lagtext. Eftersom immaterialrättigThe international intellectual property system has been established on the principle that intellectual property rights are territorial and therefore limited, with respect to content and scope, to the country of protection. The territorial limitation in intellectual property law is enshrined in the Berne Convention and the Paris Convention and is well rooted in Swedish law, albeit to a large extent
PPC is a new combustion concept that combines high efficiency with low emissions. This thesis is based on experiments conducted with a heavy duty PPC engine that was ran on neat methanol. A fuel that might be a candidate for future engine propulsion in large scale. By varying the inlet pressure, the corresponding inlet temperatures were found for premixed combustion, i.e. combustion in HCCI mode.
This thesis investigates a possible extension to the Standard Model: the Chirally Symmetric Technicolor Model. The motivation is to explain the origin of the electroweak interaction scale by introducing a new interaction. The thesis is based on the two-flavour Technicolor model presented in ”Chiral-Symmetric Technicolor with Standard Model Higgs boson” by Pasechnik et. al. [1], and extends it to t

Companies selling industrial machines are seeing a shift where profits are moving from new sales, towards retrieving revenue throughout the whole customer life cycle. Instead of selling new machines, the companies in the industry need to look towards what is referred to as “the aftermarket”. The aftermarket is the part of the market where spare-parts and maintenance services are sold to existing c
