Filetype
Filter är avgörande för att hantera alla typer av signaler i den digitala tidsåldern, inklusive ljud-, bild- och biosignaler. De är mångsidiga och passar ett stort antal problem. Intuitivt sett fungerar ett filter i “signal processing” som vilket filter som helst, så att vi kvarstår med väsen av ingånsgssignalen: ett kaffefilter verkar för att producera väsen i kaffebönorna; en högtalare agerar fö
By increasing the amount of CO2 emissions to the atmosphere because of using fossil fuel and the limitation of non-renewable energy sources, solar photovoltaics technology has been growing steadily and is thought to play an important role in the realm of future energies. The objective of this thesis is to investigate the potential of the rooftops for installing PV system on a small scale of 30 mu
Bröd är ett av världens mest konsumerade livsmedel. Med en färskvara som bröd och i så stora mängder uppstår alltid mycket matsvinn. Bara i Sverige är det estimerat att det slängs bröd för 2,4 miljarder kronor varje år. Detta oftast till följd av att brödet inte håller sin kvalitet tillräckligt länge. Dessutom har brödet som många äter blivit mindre nyttigt till följd av dess låga fiberhalter då mIntroduction. Bread is one of the most consumed foods in the world today. It is also the cause for major food waste streams. Most breads have turned into high glycaemic index products with low nutritional value. This master’s thesis investigated whether the soluble oat fiber ß-glucan (BG) would have positive effects on the abovementioned. There are health claims associated with different doses of
Den digital utveckling påverkar ständigt världsekonomin och ordet PropTech blivit ett världsomspännande fenomen. Digitaliseringen påverkar alla led inom fastighetsbranschen från hyresgäst till investerare och ägare. Detta genom att effektivisera och utveckla befintliga processer och lösningar. Fastighetsmarknaden har den senaste tiden haft en historiskt god utveckling vilket har gjort att digitaliDigital development is constantly affecting the world economy and the word PropTech has become a worldwide phenomenon. Digitization affects all aspects of the real estate industry from tenant to investor and owner by increased efficiency and renewing existing processes and solutions. The real estate market has recently had a historically good growth, which has amount to that the digitalization of
This project is about focusing a Gaussian laser beam that has a spatial phase profile applied by a spatial light modulator. The goal is to be able to control the shape, position and phase of the peak at the focus and to split up the peak at the focus into several peaks. Controlling the profile of the beam at the focus has interesting applications for opto-optical modulation. A code was written in
På bara några få år har en mängd gig-företag etablerat sig på den svenska arbetsmarknaden. Gig-ekonomin består av företag som förmedlar arbete mellan privatpersoner genom digital infrastruktur där gig-företagen fungerar som en utomstående part och avsäger sig rollen som arbetsgivare. Genom en kvalitativ textanalys baserad på texter hämtade från fyra svenska gig-företag, specialiserade på hushållsn
Flooding is a frequent natural hazard globally that is capable of major damage to society. The hazard is especially prevalent in Mozambique, in which many flood events with negative effects have occurred. Disaster risk management and research is therefore important in the country. However, as a developing country, it is subject to data scarcity. Matola is one of the most populous cities in Mozambi
BACKGROUND: One of the major environmental threats to human health is air pollution. It contributes to premature deaths of millions of people worldwide. Air quality issues are growing exponentially in developing countries (West et al. 2016). More specifically, household air pollution that results from indoor cooking with solid fuels is damaging to the human health in LMIC. About 54% of global popu
Levande celler innehåller så kallade organeller som utför olika uppgifter och är viktiga för cellens överlevnad. Deras roll kan liknas vid organens funktion i våra kroppar. Många utav dessa organeller har en membranvägg, som skyddar dem från resten av cellens inre. Det finns dock även organeller som saknar omgivande membran och istället, likt en vattendroppe, hålls ihop av ytspänning. Dessa membraRecently, a field theory approach, using the Hubbard-Stratonovich transformation, was developed to describe biomolecular droplet formation in cells, through liquid-liquid separation. The approach has the disadvantage of having a complex effective energy function, meaning Monte Carlo simulations become difficult. Therefore, it has been suggested that the complex Langevin equation could be used inst
The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. In this thesis, I analyse a region of the Idefjorden terrane, colloquially known as ‘B-Bulan’, cl
Pollinators provide valuable ecosystem services to agricultural landscapes; however, they are threatened by several factors of decline. Particularly for wild pollinator species, the effects of stressors neither individually nor in interaction with each other are well understood. Pesticide use is known to impart various lethal and sublethal effects on pollinator populations, and this use is likely
Studiens syfte har varit att studera hur mäns våld mot kvinnor framställs som ett problem i kommunala handlingsplaner. Ytterligare har avsikten varit att undersöka vilka antaganden samt implikationer problemframställningen utgörs av.

The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and
In this thesis several stochastic volatility models are presented and used to estimate the risk of a collection of Swedish stocks, as well as of a portfolio consisting of said stocks. Model parameters are estimated using the PSAEM algorithm. It is concluded that these model are adequate at estimating the one day ahead five percent Value at Risk of the data in terms of conditional coverage.
Craft breweries in Sweden are steadily increasing and they face a major challenge with the byproduct that is generated in the brewing process. The by-product is called wet spent grain (WSG) and the biggest challenge lays in its’ high moisture content which will make it spoil within a few days. Craft breweries are being conscious of sustainable practices when producing beer and the aim of this thes
To reach internationally agreed climate targets, it is especially important to phase out coal-powered electricity generation in favour of low-carbon technologies. Several governments have pledged to phase out coal power. However, coal phase-out is hindered by resistance of negatively affected workers, companies and regional governments. To reduce such resistance and to increase fairness within the
The core objective of this project was to design a controller for a drone (or quadcopter) that would allow the drone to keep a target in the center of a video filmed by a camera mounted on the drone. This was done by controlling the pitch of the gimbal, on which the camera was placed, and the yaw of the entire drone combined with using an image recognition program that could identify the target. F
