Manual tuning of PID controllers can be very time-consuming and that is why automatic tuning was developed. The conventional automatic tuners use a relay instead of controller in a closed loop system to obtain stabile oscillations. The information from a relay experiment is later used to calculate PID control parameters with different tuning rules and there also exist systems that, apart from the
This thesis aims to provide information regarding which critical success factors that are beneficial for small and medium enterprises when implementing Robotic Process Automation. It has been done by identifying 11 critical success factors from 14 academic research articles treating Critical Success Factor’s in Customer Relationship Management and Enterprise Resource Planner implementations. The 1
Syftet med examensarbetet var att undersöka huruvida RFID-tekniken och streckkodsläsning i Androidtelefoner gick att tillämpa i en biblioteksmiljö. Fem bibliotekarier intervjuades för att utreda vilka funktioner som hade varit av värde i det vardagliga arbetet. Utvecklingen skedde i Android Studio med Java där verktyg som Gradle och J-Unit användes. CI/CD tillämpades i utvecklingsprocessen. En weThe purpose of this study was to examine the possibility of implementing RFID and barcode scanning in mobile Android phones for usage in a library setting. In order to investigate the functions that would be useful to librarians in their daily work, five interviews were conducted with said target group. Development was made with Java in Android Studio with tools such as Gradle and J-Unit. CI/CD w
This paper examines the “back-testability” of Expected Shortfall and if different backtesting methods produce similar results, with the aim of illuminating whether various markets have any effect on the methods’ ability to perform. In order to answer this question, the three backtesting methods – Test 1 and Test 2 by Acerbi & Szekely, and the Approximative Quantile Test by Emmer et al. – are i
This master degree project has had the purpose of designing a chair for small scale serial production in Sweden. Origin has been a big focus point, and the wood has been carefully selected to minimise ecological footprint through transportation of the product. Another focus point has been the complicated process of designing a chair that is unique. The report includes the background of the carpent
The nearest neighbour level spacing distribution and the Δ3 statistic of level fluctuations associated with very high spin states (I ≳ 30) in rare-earth deformed nuclei are analysed by means of a cranked shell model. The many particle-many hole configurations created in the rotating Nilsson potential are mixed by the surface-delta two-body residual interaction. The levels in the near-yrast region
The purpose of my thesis is to understand in what ways economic and productive transnationalisation affects political and social participation in the local level. Particularly, what I wish to explore are the effects of integration into the global economy over labour movements in peripheral regions. I study the ways in which workers of salmon firms in the areas of Puerto Montt and Chiloé organise a
Vindkraft är en förnyelsebar energikälla som ligger i tiden och är den energikälla som idag växer snabbast i världen. Eftersom Sverige har stor utbredning och långa kustpartier finns det goda möjligheter att utnyttja vind som energikälla. Sveriges riksdag har därför satt ett mål att ungefär tiodubbla energiutvinningen från vindkraft till år 2015. Den generella uppfattningen om vindkraft i Sverige
The main sustainability goal of many small islands in the North Sea is to become self supplied in renewable energy in 20-30 years. The majority of the islands are trying to repeat Samsø‘s success – to make a transition towards energy sustainable system by new energy production from local renewable sources such as wind, solar and biomass. However, for other islands like Spiekeroog island, a tourist
Idag finns det många olika sätt att avbilda människokroppens inre. Två av de vanligaste metoderna som används idag är magnetresonans (MR) och datortomografi (CT). MR använder sig av starka magnetfält och radiovågor för att skapa snittbilder av kroppen, medan CT använder sig av röntgenstrålar. Båda kamerorna har sina fördelar och nackdelar. MR ger bättre vävnadskontrast, det vill säga det är lättar
Tidigt under åren i arkitektskolan lär vi oss att forma och utforska våra egna kreativa processer. Dessa blir djupt personliga, och i detta projekt vill jag försöka formulera och utforska mitt sätt att arbeta. Under min studietid har jag upplevt att de största problemen jag haft under designprocessen varit att jag tenderat att bli för självkritisk i ett tidigt skede, vilket har resulterat i låsninIn the early years of architecture school, we learn to shape and explore our creative processes. These become deeply personal, and in this project I want to try defining and exploring my way of working. During my time as a student, I have experienced the biggest problems I had during the design process were that I tended to be too self-critical at an early stage, which resulted in blockages in the
This thesis examines Swedish forest biological soil research in its newly institutionalized form, performed in relation to industrialized silviculture, during the years 1916-1923. The main objective is to analyze how the early forestry scientists pursued, and legitimized, knowledge on forest soil for industry and society, and also to draw attention to less considered empirics within history of sci
Prior articles and reports have named Credit Default Swap (CDS) spreads as a plausible indicator of default risk. In this report, the authors present a significant correlation between CDS spreads and two other more acknowledged methods of measuring default risk probabilities; the modified Merton model and credit ratings from the rating institute Moody’s. The tests are implemented by Spearman’s ran
Jag har studerat en klass i nian som haft som skoluppgift att skriva var sin egen låt. Förutom att observera hela klassen har jag dessutom följt fyra elever under deras musikskapande process. För att besvara min forskningsfråga om hur ungdomar gör när de skapar musik som skoluppgift, har jag använt mig av kvalitativ metod och jobbat med observationer och intervjuer. I teorin har jag valt att titta
When a change of a signal installation will be implemented, the process takes the approach of two guiding documents that Trafikverket provides; BVF 544.94001 Teknisk säkerhetsstyrning and BVS 544.92100 Ibruktagandebesiktning av signalanläggningar. The problem with the two documents is that they sometimes treat the same things in the commissioning process, which means that there is a risk of contra
The United Kingdom’s response to the pressing biodiversity decline in England includes the Biodiversity Net Gain (BNG) policy and is operationalised through DEFRA’s Biodiversity Metric, which quantifies biodiversity into ‘biodiversity units’. This thesis evaluates how effectively the metric reflects real biodiversity outcomes at the rewilded Knepp Estate in West Sussex. Using 2005 as a baseline an
