Wavelet theory, which shares fundamental concepts with windowed Fourier analysis, introduces the notion of scale in an effort to aid in joint time-frequency analysis. Having century-old roots, much of the essential research on the subject of wavelets was conducted during the 1970s and 1980s. Despite being a rather young toolset, wavelets have shown to be very useful when studying signals with tran

Utifrån den potentiellt utsatta situation som personer med funktionshinder har i relation till de anställda på boende för stöd och service syftar uppsatsen till att undersöka de anställdas förståelse av sitt uppdrag och dess mål, samt undersöka hur de genom sitt narrativ konstruerar LSS-användaren. Intervjupersonernas förståelse av sitt arbete är främst att stödja och hjälpa LSS-användare, men ytt

Baddeleyit är en zirkoniumoxid som normalt sett inte är stabil i kiselmättade miljöer, utan då omvandlas till zirkon. Mitt arbete kommer att handla om ett extremfall då baddeleyit har påträffats i en kvartsit i södra Ghana. Zirkoner med baddeleyitomvandlingar hittas precis vid kontakten till en deformerad granit. Efter att ha undersökt både bergarten och de enskilda zirkonkornen i ljusmikroskop ocBaddeleyit is a zirconium oxide that normally is not found in silica rich environments, because it’s not stabile. It will rather react and form zircon. My paper will deal with an extreme case where the baddeleyit was found in a quartzite I the southernmost part of Ghana. Zircons with baddeleyit inclusions were found right above a contact with a deformed granite. After some studies on the rock and

This thesis was written in collaboration between Faiveley Nordic in Landskrona and the Division of Production and Materials Engineering at Lund University. It was set out to find improvements or cost reductions of the overhaul process at Faiveley. The overhaul process at Faiveley is a process were used and worn train brakes are taken apart and overhauled for further use. To achieve this goal, amon

In recent years radical right parties have gained electoral strength across Europe, while the vote share of social democratic parties has declined. Using regional data and two fixed effect models this study investigates the impact of manufacturing employment and a range of other economic and demographic variables on the vote share of these parties in both national and European parliament elections

Potato cultivation is vast for many agricultures in southern Sweden. What many might not be aware of, is how much pesticides which are used in the cultivation process. In "Late blight prediction and analysis"[1] predictions of late-blight attacks was modelled on potato-corps using Elastic Net among other methods. This thesis is an algorithmic complement describing Alternate Direction Met

Modifications and new approaches for breach response and forensic investigations for compliance with the General Data Protection Regulation, GDPR, is to be expected in May 2018. This paper brings forth the conclusion that engagement from top management is crucial in order to comply with the GDPR requirements. The importance of having a vision and a strategy assessing the matters of breach response

Denna uppsats handlar om att undersöka och analysera om Sverige skulle kunna stärka skyddet för arbetstagare när det kommer till frågor som rör lön, genom att införa allmängiltigförklarat kollektivavtal. Undersökningen kommer att göras genom att jämföra Sverige och Finlands kollektivavtalssystem, hur de är uppbyggda och vad som är specifikt för respektive land. Länderna i fråga är till synes väldiThis essay is about investigating and analyzing if Sweden could strengthen the protection for workers when it comes to questions relating to employment wages, by introducing extended collective agreements. This will be done by comparing Sweden's and Finland's systems of collective agreements, how they are constructed and what's specific for each country. The countries in question are v

För en kemisk industri är lönsamhet av största vikt, vilket uppnås via effektivisering av tillverkningsprocessen och ökad försäljning. I TMP-fabriken har man nu nått maximal produktionskapacitet genom att undersöka specifika driftparametrars inverkan på produktionshastigheten. För att komma vidare och kunna öka produktionshastigheten ytterligare måste varje steg utvärderas, modelleras och optimeraThe aim of this thesis work was to create a model describing the crystallization process of sodium formate and to calibrate this model to real process data. Sodium formate is a by-product formed during the production of Trimethylolpropane (TMP). The model used is based on the population balance equation and include crystallization mechanisms such as particle nucleation, growth and agglomeration. T

Programmeringsspråket Rust utvecklas av en grupp som anser att det saknas språk som passar lågnivåutveckling och samtidigt är säkra. Rust har utvärderats genom att översätta 5000+ rader C-kod i ett inbyggt system. Rust levererar säkerhet, är smidigt och är inte resursintensivt.Rust aims to bring safety to low-level programming by using zero-cost ab- stractions. These provide, among other things, guaranteed memory safety and threading without data races. Garbage collected languages have become popular to guarantee safety, but in performance critical, memory limited or real time applications, it is not an ideal solution. Rust is safe and still has manual memory managemen

This research paper introduces the concept of family/non-family boundary work as a form of boundary work. This study focuses on family member and non-family member employees working in a family-owned business who are involved in top management positions within the company. Through an analysis of narratives and interactive practices within the work context, based on ethnographic interviews and obse

FlatFrog develops a system for interactive displays, containing a glass where it’s concave shape is critical for the functioning of the system. By using simulation at an early stage of the product development process, the behavior of the glass and weak points in the structure can be detected even before prototyping. The purpose of the work was to simulate areas that, with relatively small means, c

Fler och er bor i städer, en miljö som ofta beskrivs i kontrast till natur. Men även om stadsmiljön är arti ciell och på vissa sätt själva motsatsen till begreppet natur, så är naturen ständigt närvarande i staden i form av klimat, växtlighet, årstider och väder. Att skapa möjligheter för upplevelser av natur är viktigt för människors välmående i staden. I denna ofta hektiska och intrycksmättade m

The purpose of this report is to find out which composition of fibres in clothes are the easiest to ignite when exposed to a smouldering fire (i.e. a cigarette). The end result of this report were several rankings concerning the ignitability of sweaters made of polar fleece, WCT-overalls, knitted cardigans (sweaters), dressing gowns (bathrobes) and sweatpants. Several conclusions could be made and

While female labour market participation is increasing worldwide, the development in Chile is slow and concentrated to the capital city of Santiago de Chile. Education has been found to increase female labour market participation in several studies, where my thesis contributes to the research with more careful analysis of the effects of higher education. Rather than analysing the joint effect of h

In Białowieża primeval forest (BPF) wolves Canis lupus supress red deer Cervus elaphus foraging via behaviourally-mediated, non-consumptive effects. Humans provide an additional risk factor differentially exhibited between areas devoid of human intervention and areas with high human hunting and foresting activity. The aim of the study was to test the behavioural responses of red deer to risk effec
