In this project, an electromagnetic side-channel attack has been made by exploiting the information leakage from a field programmable gate array (FPGA) and an implemented advanced encryption standard with a 256-bit key (AES-256). The FPGA-board was a Nexys-4 from Digilent with Artix-7 FPGA. The attack was partially successful. A few subkeys were successfully extracted from AES-256 with only 2000-3
Millimeter-wave radar imaging has potential uses in applications such as material analysis and medical in-vivo scanning of tissue. This thesis is about measuring objects using a millimeter wave radar, implement radar imaging algorithms and evaluate the resulting images. The measured objects are plates and rods made of metal and a rod made of acrylic glass (PMMA). The objects are measured using the
För att skapa ett miljövänligt plastmaterial blandades bioplast in i traditionell oljebaserad plast. Detta nya material erbjuder intressanta materialegenskaper och är ett grönare alternativ till plast helt baserad på fossila tillgångar.Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. In this report, the possibilities of
Many studies on how to encourage pro-environmental behaviour have been done. However, they have tended to focus on individual behaviour in isolation of social interactions despite increasing scepticism about the effectiveness of this approach in promoting the necessary transition toward a more sustainable society. Such a transition constitutes a central part of the transformational mode of sustain
Kenya is one of the world’s nations with the most severe problem of education inequality. Low-cost private schools (LCPS) have therefore become the main access to education for most families at the bottom of the pyramid (BOP), notably in remote and slum areas. In Homa Bay, one of the remote regions in Kenya, over 50 percent of its poor families’ children are attending these LCPS. However, due to s
När läkemedel produceras bildas även en massa biprodukter. Dessa biprodukterna kan många gånger vara mycket skadligare än vad själva läkemedlet gör nytta. Därför renar man upp läkemedel med en process som heter kromatografi. Kromatografi är som ett rör som är fyllt med något typ av sand eller sten. För att sedan rena upp sitt läkemedel låter man sin blandning med produkt och biprodukt åka genom koChromatography was first described in the 1903 by a Russian scientist. Later on chromatography was almost forgotten until the 1940s when two British scientist published a study about liquid chromatography. They were later awarded with the Nobel prize in chemistry for their work in chromatography. Chromatography has since then developed a lot and nowadays several different kinds of liquid chromatog
Problem - Although experiential and social learning theory have contributed to our understanding of the entrepreneurial learning process, a major limitation is the focus on learning of the individual entrepreneur. As most start-ups work in teams, understanding the organizational learning process is important. Aim - The purpose of this study is to discover how start-ups learn by participating in an
Förnyelsebara bränslen vinner allt större mark inom energisektorn och biomassa är ett av de mer lättillgängliga alternativen. Eftersom det rör sig om fasta bränslen kan det dock vara svårt att hantera. För att göra det mer lätthanterligt kan man utvinna energin i form av gas som man sedan förbränner. Men vad innehåller gasen? Och hur tar vi reda på det? Först och främst måste vi reda ut begreppetThis thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. For pyrolysis, the sample is placed into the center of a cruciform aluminum pipe, flushed with Ar, at room temperature. The

The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated. Electric vehicles (EVs) is an energy source that today is being underutilized. Therefore, research has bee
Visst vore det bra om färre kvinnor dör som följd av komplikationer vid förlossning, eller att ett nytt läkemedel mot depression kommer ut på marknaden? Med mer insikt om ett biologiskt läkemedels fysikaliska stabilitet kan detta bli verklighet. I detta mastersarbete har det biologiska läkemedlet carbetocin studerats med avseende på just detta. Vanliga läkemedel som vi är vana vid att ta i tabletCarbetocin is an uncharged cyclic therapeutic peptide with a tendency to aggregate in solution. Aggregation is undesirable since it, for example, can lead to loss of pharmaceutical effects. To gain a better understanding of peptide aggregation, along with a potential to develop better drug formulations, aggregation of carbetocin was studied. In focus were soluble aggregates in contrast to phase-se
Loudspeakers are used in many different applications and play a vital role in various types of entertainment and communication. To optimize the listening experience, there is a need for an adjustment process to compensate for any effects the environment might have on the loudspeaker’s performance. This thesis presents an adaptive method that utilizes an arbitrary amount of loudspeakers and microph
Digital visual effects (VFX) has become increasingly primary to film and TV production. With major media conglomerates historically exercising great influence over the spatial distribution of industry activity, production localisation has been determined by cost-effectiveness and access to local tax incentive programmes. Despite lack of tax incentives, Swedish VFX firms are capturing an increasing
Sustainable development is currently a topic of great interest due to United Nations’ Brundtland report in which a strong case is made for the need to transform societies towards a more sustainable orientation. Despite relatively few studies on the subject, sustainable entrepreneurs are claimed to play a significant role as change agents in sustainable development. For this reason, we chose to mak
Many economists agree that financial development and economic growth have a positive relationship, that financial structures have been critical for many countries to achieve modern economic growth. In the past decades, foreign investment has become more widespread in the entrepreneurial world, and the banking sector has not been an exception. Mexico experimented during the late 1990’s an unprecede
Syftet med denna studie är att undersöka olika faktorers påverkan på budpremiens storlek vid svenska-, norska- och finska publika företagsförvärv. Vidare syftar studien till att urskilja vilka faktorer som har en signifikant korrelation med budpremien för att bidra till en förklaringsmodell, med ambitionen om att minska värdeförstöring i samband med förvärv. Genom en deduktiv arbetsmetod analyseraThe purpose of this study is to examine various factors’ influence on the size of the bidding premium in Swedish, Norwegian and Finnish public acquisitions. Thus, the study aims to identify which factors have a significant correlation with the bid premium in order to contribute with an explanation model. The ambition is to reduce the value destruction that often occurs in connection to acquisition
Hur låter musiken som spelas av atomer? Även om de inte kan sjunga så kan atomer – de små byggstenarna som bygger världen – interagera starkt med laserljus och då skapa kortvariga ljusblixtar som är lika harmoniska som musik. Att förstå hur laserljus och ljusblixtar är relaterade är genom deras interaktioner med atomer. Detta kommer att hjälpa oss att följa aktiviteten som händer så snabbt att denLight-matter interactions can be used to probe both light and matter as they yield information on a system's state. On the ultrafast timescale, it is possible to employ these interactions to probe fast-occurring phenomena. In particular, one of the few tools for ultrafast spectroscopy are coherent attosecond XUV pulses: light pulses in the extreme ultraviolet range (XUV) whose typical duration
This essay examines the concept of authenticity in relation to William Blake in general and specifically in The Marriage of Heaven and Hell (1790). The Romantic period idealised authenticity but focussed studies into Blake’s relationship with authenticity are relatively few. Previous research contextualizing Blake explores themes such as education, politics and religion, but recent research propos
With recent increased media attention on sexual assault against women, many people question why so many women do not report the crimes. One key may reason lies in the phenomenon of victim blaming. This study examined the effects of social dominance orientation (SDO) and perspective-taking on victim blaming after a sexual assault using a between-subjects experimental design. 111 participants respon
