Determining fatty acid composition within different lipid classes is a time-consuming process. Generally, normal phase chromatography is used to separate lipids by lipid class, based on differences in polarity. Fractions of this separation are then collected and derivatized into fatty acid methyl esters (FAMES), followed by analysis with gas chromatography and flame ionization detection (GC-FID).

In this Master Thesis we aim to evaluate the Robust Header Compression protocol in cel- lular IoT. The initial results show that RoHC may decrease the energy consumption signif- icantly due to its reduction of the header size. The reduction in the header size decreases the required transmission window which in turn decreases the energy consumption. The result also show that Robust Header Compress

We study the key properties of the quantum SU(2) Yang-Mills ground state and its possible role in the early Universe, in particular, as a driver of Cosmic Inflation. Using the effective action approach and separating the Yang-Mills field potential into homogeneous (condensate) and inhomogeneous (fluctuations) components, we reproduce the conformal-time solutions for the two different types of the

He has received considerable critical acclaim, notably winning the Man Booker International Prize in 2015. He initially became famous, to a wider audience outside Hungary, through director Béla Tarrs adoption of his novels. Satantango is his debut novel and chronicles the miserab

Edward L. Bernays (1891 - 1995) was an American PR-pioneer who came into prominence during the 1920s. He made a significant contribution to the theorizing and legitimization of the field. This started with Crystallizing Public Opinion(1923)where he defined, justified and celebrated the profession. He also staged several notable PR-campaigns; e.g. ”Torches of Freedom” and ”Light's Golden Jubile

A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. This thesis aims at testing different methods for classifying UAV images from an agricultural crop site in the so

Considering the fact that many people are oppressed because of their gender and race, whilst others are privileged because of theirs, we should reflect on the concept of intersectionality. This paper aims at reading Willa Cather’s My Ántonia from an intersectional perspective with the purpose of opening up for certain themes. In addition, it also sought to explore how reading the novel from an int

I detta examensarbete, som skrivits i samarbete med Svenska Turistföreningen (STF), beräknas och utvärderas de växthusgasutsläpp som driften av föreningens fjällstugor, belägna i väglöst land, ger upphov till. Beräkningarna baseras på de fyra fjällstugorna Alesjaure, Sälka, Kårsavagge och Nallo.

“Light creates ambience and the feel of a place, as well as the expression of a structure.” Le Corbusier With the current urban pressure and large waves of immigration, cities are facing an increase in population and therefore urban densification. This increase in building quantities affects daylight reaching the public space. City densification is easily readable in large metropolitan areas, wh

Det är ofta arkitekter får frågan “Varför ritar ni så fula hus nuförtiden?”. Majoriteten lekmän tycks föredra estetiken hos äldre hus framför det som byggs idag. Ämnet är aktuellt i olika medier, men problemet är att det sällan bedrivs en konstruktiv diskussion mellan de två sidorna. Förespråkarna för en mer traditionell arkitektur smutskastar arkitekterna och arkitekterna hånar kritikerna. I mittArchitects are often asked the question ”Why do you design such ugly buildings nowadays?”. The majority of laymen seem to prefer the aesthetics of, what might be referred to as period or traditional houses, to what we build today. The issue is being much discussed in the media, but in general, the discussions are not constructive. People that advocate a traditional architecture excoriate architect

Negative environmental impacts generated by new buildings and the built environment needs to be reduced in order to contribute to mitigation of anthropogenic global warming. Sustainable building certifications such as Miljöbyggnad and DGNB was introduced as a measure to transition into more sustainable buildings.

Genom att utnyttja vissa strukturer i den finansiella marknaden kan man skapa prognoser för finansiella instrument. Prognoserna man kan man utnyttja i in en algoritm som optimerar en portfölj av olika instrument. Resultatet är en portfölj som över mer i värde än själva instrumentet. Vi har all hört att man bör spara pengar inför pensionen. Många väljer att spara pengar genom att placera pengarna In this thesis model predictive control (MPC) is used to dynamically optimize a portfolio where the data is sampled every 5 minutes. Previous research has shown how MPC optimization applied to daily sampled financial data can generate a portfolio that exceeds the value of standard portfolio strategies such as Strategic asset allocation. MPC has been found to have a computational advantage when ret
