One of the most promising alternatives to reduce global CO2 emissions is the replacement of fossil fuels by biofuels in the transportation sector. Production of biofuels from energy crops or residues arises as an answer, but the technology is still costly to be implemented at commercial scale. This project proposes reducing bioethanol production costs by using animal bedding as feedstock. The main

Hur kan man utföra riskfyllda experiment i stor skala utan att det innebär en enorm kostnad? Man låter en dator göra en gissning av resultatet! I detta examensarbete presenteras hur ett simuleringsprogram tog sig an storskalig produktion av vätgas, och vilka utmaningar det medförde.A simulation in bioprocess technology was carried out in order to evaluate the accessibility and adequacy of the simulation software SuperProDesigner used on an academic level. This was done by recreating an existing process and studying the results as well as observing the diculties and limitations along the way. The study in question was a biohydrogen production plant consisting of three parts.

Unsustainability is persistent despite growing awareness that the industrial way of life, its modes of production and consumption need to be transformed. In academic sustainability contexts, however, attention is rarely paid to how industrial societies basically operate and how our everyday life is implicated beyond the usual suspect: consumerism. I argue that it is work, as central social relatio

The modern mobile networks such as the Cloud Radio Network Access (C-RAN) are developing to deal with upcoming requirements in the current generation $4$\textsuperscript{th} Generation (4G) and the upcoming generation i.e. the $5$\textsuperscript{th} Generation (5G). One of the challenges in the modern communication systems is the required high data traffic specially at the fronthaul. Fronthaul in

In the scientific literature and in the media there is a growing concern about toxins in aircraft originating from the air conditioning system as a result from pyrolised jet engine and hydraulic oil, and more recently also de-icing fluid. Many crews have reported long-term neurological and respiratory health effects, but also acute impairment or even incapacitation while performing their flight du

Coreference is a relationship between two or moreexpressions in a text when these expressions referto the same person or thing. Coreference solving,the identification of sets of coreferring mentionsin a text, is a well-studied problem in the fieldof natural language processing (NLP), the com-putational analysis of text. As an example, con-sider this short text:John drove to Judy’s house.He made heIt is said that coreference is difficult to explain, but easy to comprehend; everyoneknows coreference, they just don’t know that they do. We trained a computer toknow it too! Coreference resolution is the identification of phrases that refer to the same entity in a text. Current techniques to solve coreferences use machine-learning algorithms, which require large annotated data sets. Such annota

När man skapar ett läkemedel så kan det innehålla både aktiva ämnen och andra hjälpämnen. Hjälpämnena kan bidra till ett läkemedels verkan på flera olika sätt, och en grupp som ofta används är de så kallade cyclodextrinerna. Det finns tre ursprungliga cyclodextriner, alpha beta och gamma, som är ringformade molekyler med olika egenskaper på insidan och utsidan av ringen. På grund av detta så använThe effect of water on α-, β-, and γ-cyclodextrins (CD) was investigated using sorption calorimetry, differential scanning calorimetry and dynamic vapor sorption in order to understand the phase behavior and to create phase diagrams. By relating earlier X-ray diffraction patterns of cyclodextrins equilibrated over saturated salt solutions and literature regarding the cyclodextrin hydrates to the s

What is the relationship between structures of power and the spaces we inhabit? I will propose a description of how the relationship between work and housing has changed since the 19th century, and what relationships of power between worker and employer have been created as a result. I will use four case studies to highlight the changing city through the development of traditional capitalism in

Ett nytt sätt att diagnostisera graviditetsdiabetes Allt fler gravida i Sverige får diagnosen graviditetsdiabetes. Forskarna vet fortfarande inte orsaken till varför man får graviditetsdiabetes. Allt mer forskning pekar på att kronisk inflammation kan ligga bakom sjukdomens uppkomst och att inflammatoriska markörer skulle kunna användas för att säkrare och tidigare ställa diagnosen. GraviditetsDiabetes is one of the most common chronic diseases in the world. Gestational diabetes mellitus (GDM) presents during pregnancy and significantly increases the risk of a number of adverse consequences for the fetus and mother. It is thought that low-grade chronic inflammation plays an important role in GDM. The inflammatory biomarker soluble urokinase plasminogen activator receptor (suPAR) has bee

Monte Carlo (MQ) method is a powerful tool to approximate high dimensional integrals. The disadvantage of ordinary MQ is the slow convergence rate by cause of the essential randomness of this method. Computations of this convergence can lead to pure time consuming. Quasi-Monte Carlo (QMC) method yields considerably better results since this method is a deterministic alternative which uses Low-Disc
