Många system kan representeras som grafer, alltifrån neurala nätverk och transportnätverk till något så vardagligt som våra umgängeskretsar. Om exempelvis Andrea är vän med Jona- than, så kan vi rita ut Andrea och Jonathan som var sin prick på ett paper och låta deras vän- skap representeras av en linje. På samma sätt kan vi enkelt lägga till fler personer (prickar) och rita fler linjer till alla There are many systems which can be represented as graphs, to say the least the networks in which we communicate with each other. Thorough understanding of graph structures enables better predictions of the dynamics in real life networks, such as the spreading of a disease in a community or failure propagation in a system. This thesis investigates information propagation over connected undirected

The space of open source supply chain attacks is ever evolving and growing. There is extensive previous work identifying and collecting open source supply chain attacks, as well as identifying patterns in these attacks and proving that machine learning models may be able to detect these patterns. The aim of this thesis is to develop such a system and study its efficacy in detecting attacks. To ac

Ferroelectric memories pose as a potential candidate as resistive memory devices that could be used for in-memory computing and artificial synapses. One promising type of ferroelectric memory device is the ferroelectric tunnel junction (FTJ). The basic functionality of a FTJ device is based upon the fact that ferroelectric materials display two distinct polarisation states which could be switched

This study aims to examine how NATO-states overtly responds to cyberattacks committed by the believed Russian government sponsored hacker group Fancy Bear. After the end of the Cold War the regulation and acceptance for different kinds of covert actions changed in turn with the change in global power dynamics. The current digital environment develops new ways in which states can spy, gather inform

Cutting carbon emission from road transports worldwide is a key component in limiting global warming, and electrification is one of the most likely automotive technologies to achieve this goal. Therefore, Elonroad is developing an electric road system that will allow its users to charge while driving. This allows greater range and a reduction in battery sizes. This master thesis is therefore aimin

As information technology has grown and evolved, so has the need of securing the information. It is important to evaluate both the security of systems and the methods which are used for the evaluation. One method for finding security vulnerabilities in a system is penetration testing. The goal of this thesis is to evaluate some tools and methods for penetration testing. The methods were examined

Large digital platforms impact the entire internal market of the EU. In particular, three challenges characterise their relationship with businesses and end-users, “access to data”, “imbalanced bargaining power”, and “degrading data privacy”, where the common denominator is personal data. This thesis investigates to what extent these challenges are regulated in the GDPR, Article 102 TFEU and the D

Autenticitet ses av vissa forskare som en central del av välbefinnande. Mot bakgrund av detta ville vi fördjupa förståelsen för upplevelsen av autenticitet hos svenska gymnasieungdomar. Inom ramen för projektet “Välbefinnande och självkänsla på gymnasiet” på Lunds universitet genomförde vi semistrukturerade djupintervjuer med sju ungdomar i årskurs tre på gymnasiet om deras erfarenheter av att må Authenticity is viewed by some researchers as a central aspect of well-being. Considering this, we aimed to deepen the understanding of the experience of authenticity among Swedish high-school youths. As part of the research project ”Well-being and self-esteem in high school” at Lund university, we conducted seven semi-structured in-depth interviews with third year high school students about their

This thesis aims to shed light upon the cathar church and its expression of power and hierarchy in their rituals, such as the consolamentum, in conjunction with their theological view of said power and hierarchy. With a hermeneutic theory and a text analysis I read and aim to examine the cathars' own texts in its own context. Through my reading of their theological and ritual texts. I make the

This is a bachelor thesis containing a thematic text analysis of trial documents from the International Criminal Court (ICC) in the case of The Prosecutor v. Bosco Ntaganda. Mr. Ntaganda is up to the present the only one who has been convicted of rape and sexual slavery in the context of war crimes and crimes against humanity by the ICC. The aim of the thesis is to identify and analyze what the IC

Tourism is one of the fastest-growing economic sectors in the world. Due to that, many developing world’s regions with limited economic activity adapt tourism as a development strategy. The point of departure is a critical consideration why tourism, while producing such immense economic benefits, frequently also perpetuates already existing socio-economic, cultural, and environmental dysfunctions.

This paper examines the sufficiency of a trading method based on singular value decomposition (SVD) of past stock prices. The SVD method is frequently used as a tool to reduce data noise, compress big-data, and analyse data components. Hence, the method is well suited to form a ground for a predictive tool of price developments. From the predicted pattern, a strategy was formed by construction of

Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int

Wireless Power Transfer (WPT) technology has experienced phenomenal success in the application of wireless charging of smartphones. With the Qi Specification becoming the dominant standard, wireless charging's convenience goes beyond cable-free charging to facilitate interoperability between chargers and devices from different vendors. For wireless charging to operate correctly, the power tr

Solen är den mest välkända stjärnan för oss. Den tycks vara evig och oföränderlig, utan den hade liv på jorden inte varit möjligt. Noggrann observation och årtionden av forskning har gjort det möjligt för oss att förstå hur solen kom till, hur den utvecklades, och hur den så småningom kommer upphöra att existera. Vi har upptäckt att den är långt ifrån evig och oföränderlig. Den expanderar eller krObserved population of giant planets around evolved stars shows a paucity of planets with semi-major axes below 0.5 au, in contrast to main sequence stars where those planets are present. This lack of close-in planets has been attributed to either planet engulfment due to tidal forces or substantially higher masses of evolved host stars implying dierent initial semi-major axis distributions, becau

2015 placerades Sverige som världens tredje minst korrupta land på Transparency International årliga lista över korrupta länder. Även om vi kanske inte förknippar Sverige med korruption rapporterar media återkommande om tveksamma ageranden från myndighetsutövande personer och privata tjänstemän. Vi saknar en renodlad korruptionslagstiftning i svensk rätt. Ett av rättsordningen främsta redskap mot In 2015 Sweden was ranked third least corrupt country in the world according to Transparency International. Even though we may not think of Sweden as a corrupt nation, media continue to report about questionable acting from Swedish authorities. There is a lack of anti corruption legislation in the Swedish criminal law. Therefore the anti bribe legislation is essential. Scholars consider that the S

I en värld där klimathot och resursbrist har växt fram till ett allt större problem på världsledarnas agenda har vikten av hållbar utveckling identifierats som en nyckelfråga i vägen mot en bättre framtid. En metod för detta är industriell symbios, som innebär att olika företag och organisationer gemensamt utnyttjar energi, nyttigheter, material eller service, för att på ett innovativt sätt skapa In a world where climate change and resource scarcity have grown to some of the main issues on the world leaders’ agenda the importance of sustainable development has been identified as a key challenge in the path towards a better future. One method for this is industrial symbiosis, where different entities collaborate over energy, utilities, materials or services to create value and lower cost an

Buildings are getting taller due to increased urbanisation and densification of cities. More advanced construction methods and the desire to construct impressive buildings is also supporting the trend. Due to their inherent slenderness resulting in low eigenfrequencies, these buildings are susceptible to wind-induced vibrations which can be highly disturbing for occupants. Already barely perceivab

Den rådande och även allmänt kända teorin för Universums uppkomst kallas Big Bang-teorin. Big Bang tros ha inträffat för cirka 13,8 miljarder år sedan och beskriver en tid när vårt Universum befann sig i ett mycket varmt och energitätt tillstånd, som snabbt kyldes ner för att bilda de första lätta atomkärnorna bara några minuter in i sitt unga liv. Även om det tog ytterligare 100 miljoner år för
