Stora mängder metadata måste sparas för att kunna användas i utvecklingssyfte. Genom att använda sig av databaser, kan metadatan effektivt sparas. Men vilken databas passar bäst för vårt system? Det är vad vår uppsats har svarat på.Choosing the correct database for an application can be a daunting task for an application owner. There is a vast plethora of different options to choose from, where choosing a NoSQL database or a relational database management system built on SQL is the most defining decision. With the ever-increasing amounts of data that is produced, more and more databases are emerging. In this report we comp

This thesis examines four exchange rate pairs of fiat currencies in comparison to four of the main cryptocurrencies based on market capitalization. The primary goal is to obtain new estimates for the cryptocurrencies based on the use of the GARCH (1.1) model, the EGARCH (1.1) model and simple historical volatility (SHV). The volatility is regarded as an essential risk measure in the management of

Frågan om gentrifiering och arkitekturens roll för hur stadens förändras ledde mig vidare till den undersökning av konstnärliga verksamheters territorialitet som presenteras i det här arbetet. Gentrifiering är en rumslig förändringsprocess som omstrukturerar staden socialt och materiellt. Konstnärer och konstnärlig verksamhet pekas ofta ut som en viktig inledande faktor för gentrifiering genom att

Utgångspunkten för examensarbetet är situationer i kommunal myndighet där personer som skulle kunna kvalificeras som rättshaverister skapar utmaningar för kommunala myndigheter. Examensarbetet innehåller en beskrivning av vad innebörden av begreppet rättshaverist. För att kunna göra examensarbetet med ett juridiskt perspektiv har jag utgått ifrån tre situationer när en rättshaverist kan skapa utmaThe starting point for this thesis is the issue of querulants and the issues they do cause institutions. The thesis contains a definition of what a querulant is. To complete this thesis out of a juridical perspective I have selected from three different situations where a querulant can cause problems for various institutions. The thesis will also provide guidance for various officials in how to ac

Currently, the best ways to perform object detection in an image is to use a neural network trained on large sets of annotated data. However, in certain environments, the number of objects is large and gathering a sufficiently big set of annotated data is prohibitively expensive. In this thesis, the possibility of using computer-generated artificial data instead in such an environment, is investig

Tekniken för millimetervågor har fått stor uppmärksamhet inom 5G-kommunikation tack vare att ett stort spektrum finns tillgängligt i frekvensområdet för millimetervågor. Men mm-våglänkarna lider av allvarlig bana-förlust och atmosfärisk absorption. Strålformning,, att skapa riktade strålar som kan riktas åt olika håll med hjälp av ett stort antal antenner, är en lovande lösning till dessa utmaningMillimeter wave (mmWave band) technology has gained a lot of attention in 5G communications, due to large amounts of spectrum being available in the mmWave frequency range. However, mmWave links suffer from severe free-space loss and atmospheric absorption. Beamforming, which generates directed beams with strong gain using multiple antennas, is one promising solution towards these challenges. In t

In December 2001, Martin Creed received the Turner Prize for his artwork Work No. 227: The lights going on and off (2000). A minimalist light installation, simplistic in its effectuation, yet complicated enough to hold questions about what art is and what role the institution plays in valuing and validating art. The purpose of this thesis is to conduct an investigation of critiques in newspaper ar

The rich cultural heritage of China is becoming less relevant and forgotten as a result of rapid urbanization and modern lifestyles. This project aims to preserve the Chinese music heritage by designing an instrument based on the Chinese zither guzheng. Despite the rising interest of traditional instruments, there are factors that are holding people back from practicing them. There have been atte

Heart rate variability as an indicator of increased morbidity has been established in previous studies. It is defined by different frequency bands, corresponding to different biological mechanisms. This thesis aims to study heart rate variability indices in the time-frequency domain through extraction from the UK Biobank dataset. Time-frequency indices for different time intervals during exercis

Questions about institutional stability and change are critically important for any understanding of political institutions. The field of Historical institutionalism in political science has described, studied and theorized institutions for decades. One of the most recurring concepts utilized in the explanation of institutional stability is path dependence, describing theoretical and empirical mec

Vår uppsats behandlar lågt valdeltagande i stora federationer, där vi valt att jämföra presidentvalet i USA med Europaparlamentsvalet i EU under två respektive tjugoårsperioder. Vi utgår från ett teoretiskt ramverk som berör olika valsystems mekaniska och psykologiska effekter, hur väljare och politiker prioriterar val genom att klassificera dem som primära och sekundära samt ett eget teoretiskt a

Whenever you walk into a Victoria’s Secret store, watch the annual runway, or encounter the brand’s angels, you feel like your prayers have been answered and you made it heaven. The brand offers such an exquisite, sexy, and seductive experience to both women and men. It is selling to women the body ideals they aspire to have and to men, the response to their deep desires; however, recently the con

With the purpose of contributing to research on the relation between identity and threat perception, this thesis comparatively examines Estonian and Lithuanian political discourse for the period of 2014-2018. Case selection is based on relatively significant difference in Russian minority population in Estonia and Lithuania. Applying Social Identity Theory, the thesis uses conceptualisations of in

”Investor-state dispute settlement” (ISDS) bestämmelser är vanligt förekommande i internationella investeringsavtal för att säkerställa det avtalade investeringsskyddet. ISDS systemet innebär att en investerare direkt kan påkalla ett skiljeförfarande mot en EU medlemsstat, baserat på det underliggande investeringsavtalet. Bilaterala investeringsavtal som innehåller en sådan ISDS klausul är vanligtWithin the area of international investment law investor-state dispute settlement (ISDS) clauses are commonly used in order to provide investment protection. The ISDS mechanism can be described as a system under which an investor can arbitrate a dispute against a host state, based on an investment agreement concluded between the host state and the national state of the investor. As this system has

The first decades of the 21st century have not been lined with the optimism that surged after the fall of the Soviet Union. Instead of pursuing a path of liberalization, Russia has relapsed to authoritarian rule and its view of the west not as an ally, but as an adversary. The war in Georgia, annexation of Crimea and the invasion of eastern Ukraine shows that Russia is once again willing to use mi

This study employs an approach to policy as discourse and examines the construction of gender equality in the EU Gender Action Plan II. Drawing from the poststructural premise that discourses affect how issues are being thought about and acted upon, the study seeks to scrutinize how gender equality is attributed with meaning by applying Carol Bacchi’s analytical methodology What’s the problem repr

Denna studie ämnar öka kunskapen om hur kommunikativ likriktning mellan institutioner upprätthåller etablerade föreställningar om hållbar utveckling i samhället. Från ett socialkonstruktionistiskt perspektiv analyseras hur FN konstruerar diskurser kring hållbarhet i Agenda 2030 samt om dessa diskurser reproduceras i Helsingborgs stads hållbarhetskommunikation. Vidare undersöks hur hållbarhetsdiskuThe aim of this study is to increase the knowledge of how communicative standardisation between institutions upholds established notions about sustainable development in society. With a social constructionist approach, we analyse how sustainability discourses are constructed within the Agenda 2030, and if these discourses are reproduced in the sustainability communication of the city of Helsingbor

Sociala medier har blivit en allt viktigare kanal för politiska partier att nå ut med politiska budskap på. Samtidigt tar partiledarna en allt större plats i politiken och blir centralare för partiers valresultat.
