Teknologiutvecklingen inom halvledarindustrin och integrerade krestsar har inom de senaste åren skett i en mycket hög takt, vilket också har medfört en förbättring av transistornas prestanda. Transistorn är grundläggande biståndsdel i elektroniska kretsar med huvudsaklig uppgift att styra strömmar och fungerar på så sätt som ett elektriskt relä. Transistorn består av tre elektroder, som kallas souDownscaling of Si-based metal-oxide-semiconductor field-effect transistors (MOSFETs) has contributed to increased microchip device density and to improve the functionality of the electronic circuits. The dimensions of state of art MOSFET is down to a few nanometers. It has been demonstrated that smaller MOSFETs are faster and more energy-efficient. However, with continued device scaling the perfor

Införandet av den nya dataskyddsreformen innebär en rad nya, stärkta rättigheter för gemene man. Stärkta rättigheter kan leda till ökad kontroll, om man är medveten om att dessa finns. Vikten av att ha kontroll över sina personuppgifter blir, i takt med att behandlingen av dessa ökar, större. I takt med att företags behandling ökar blir personuppgifter allt mer värdefulla och kallas numera för fra

The purpose of this study was to describe how life changes in psychotherapists’ own lives have affected their work. The topic was explored with a qualitative approach. The method was reflecting conversation. The result mainly illustrated how psychotherapists’ life changes and crises had affected them personally, rather than professionally. The psychotherapists mainly shared how life changes had le

From originally being used for software development, there is an increased use of agile methodologies in other areas as well. This leads to a need for further studies on the implementation of agile methodologies. The aim of this thesis is to study newly formed agile teams and their member’s perceptions of job satisfaction and examine if there are any relationships between the use of agile practice

Under många år av studier inom musik har jag som sångare upplevt att jag sällan får samma konkreta feedback som andra instrumentalister i ensemblesammanhang. Många sångare med liknande erfarenheter verkar ha upplevt samma sak. Flera studiekamrater vid Musikhögskolans lärarutbildning anser även att det finns en utbredd problematik i bristen på undervisning i hur man som framtida lärare bör ge feedbDuring my many years of music studies, I – as a singer – have rarely felt as though I receive the concrete feedback other instrumentalists get in the context of an ensemble class. Many singers with a similar background as myself seem to have experienced the same thing. Several peers at the Teacher’s Programme of Malmö Academy of Music also consider it problematic that there’s a lack in training re

Recent studies focusing on the analysis of emissions embodied in trade have shown that high-income countries are increasingly becoming net importers of emissions. This is commonly explained by the economies’ changing trade specialization in heavy and light industrial goods. The purpose of this thesis is to investigate and compare the trade specialization patterns of twelve Anglophone and Nordic co

This thesis aims at defining the improvement areas for packaging and logistics of a long shelf-life Danone Nutricia aseptic product. By literature research and interview, the author is able to build a product mapping protocol to define the sensitive components requiring particular concerns on packaging and logistics. This protocol could be implemented in both academic researches and industry proje

Om du skulle gissa på hur många komponenter det finns i din mobiltelefon, vad hade du gissat på då? 10? 100? 1 000 000? Skulle du tro mig om jag säger att svaret är runt 200 miljarder? För det är faktiskt så. I din telefon och i all elektronisk utrustning runt omkring dig finns miljontals små elektroniska byggdelar som gör vårt tekniska samhälle möjligt. Snabba, smarta och kraftfulla datorer och mThe silicon MOSFET is one of the most important components used in modern electronics. The pursuit to continue fulfilling Moore’s law by scaling transistors to even smaller sizes have driven the development forward for CMOS technologies and new approaches have been necessary. These include changing the geometry of the devices for even higher performance, like creating 3D structures (finFETs or tri

Socioeconomic status (SES) and its effect on health outcomes for an individual is generally well researched, but the different mechanisms of different socioeconomic factors are yet still not fully understood. Using cross-sectional survey data for 50+ people in Estonia this thesis aims to analyse the multidimensional nature of different SES variables to see if the SES variables have an independent

Cassava, Manihot esculenta, is the third most important staple crop in tropical re- gions. Cassava is a fibrous root that is tolerant to drought and has a flexible harvest period making it a reliable crop under poorer farming conditions (FAO, 2008). The content of provitamin A, also known as β-carotene, is unfortunately low in cassava even though there are varieties bred for a higher content. Sinc

Baker´s yeast S. cerevisiae has been engineered in order to enable xylose uptake and utilization from lignocellulosic biomass as this yeast cannot naturally metabolize this pentose sugar. However, xylose is not recognized as a fermentable sugar by S. cerevisiae and recent studies on the effect of xylose on the three main sugar signaling pathways (Snf3p/Rgt2p, SNF1/Mig1pt and cAMP/PKA) have indicat

Large particle accelerators are difficult to setup. One of the first problems that can be encountered, before production configuration is found, is the beam not passing through the accelerator. The process of guiding the beam through the accelerator is called beam threading. Depending on the accelerator complexity it can take days before the beam passes for the first time. Currently the beam thre

I dagens samhälle har vi en ofantligt hög konsumtion av förpackade drycker. För att ständigt förbättra kvalitén och korta ner produktionstid krävs en ständig utveckling av produkter. I applikationer för öppningsbarhet och skruvkorkar till förpackningar används bland annat plasten polypropen. Målet med studien som har gjorts har varit att undersöka hur plasten varierar i vissa utvalda egenskaper soThis master thesis is the result of cooperation between Lund University and Tetra Pak, performed by a student at Engineering Nanoscience, LTH. The aim is to explain how different molecular weights and molecular weight distribution of isotactic homo-polypropylene affect resulting properties. Examined properties are mechanical properties by tensile testing and tensile impact, shear viscosity by capi

This paper examines long-run and short-term dynamics of real house prices in Sweden from the first quarter in 1986 to the last quarter in 2017. To understand this, multivariate co-integration and error correction modelling approach are used. More specifically, this paper examines whether fundamental factors of demand and supply can explain the real house price development in Sweden. Evidence shows

Denna studie syftar till att undersöka hur olika typer av omskrivningar; metaforer och liknelser används av elever och lärare i ämnet Gehörs- och musiklära. Mer specifikt undersöks hur elever väljer att beskriva tre typer av färgade ackord, hur de upplever användandet av dessa beskrivningar som hjälp för att identifiera ackorden samt hur en lärare i ämnet Gehörs- och musiklära använder sig av metaThis study aims to investigate how different types of rewriting; metaphors and similarities are used by students and teachers in music theory and ear training. More specifically, how students choose to describe three types of colored chords, how they perceive the use of these descriptions to help identify the chords and how a music theory teacher uses metaphors, descriptive words and associations
