By initiative from Sweco Rail, we have made a comparison between fixed and automatic tensioning devices for tramways to determine when there is an advantage to choosing an automatic device instead of a fixed solution. Main focus has been tramways in city environment, with extra focus on Gothenburg. The report attempts to answer the following questions: • When should the choice be an automatic tens

This paper investigates differences in initial underpricing and long-run aftermarket performance between private equity-backed and non-sponsored IPOs on the Nordic main markets between 1998-2012. First-day returns are calculated to measure the initial underpricing, while a BHAR approach is used to investigate the long-run aftermarket performance. Using a sample of 227 IPOs (59 private-equity backe

The study shows how core values affect the innovation process by creating an innovation culture. Core values also create an alignment which leads to conformity and lack of new ideas. Demonstrated is also that core values function as high impact areas of innovation, meaning that employees are encouraged to generate ideas within the fields of core values. Core values are also proved to be used as a

In modern electronics, device downscaling demands atomic precision control and Atomic Layer Etching (ALE) can provide this prime capability with minute device damage. ALE, also known as layer-by-layer etching, is a technique of removing atomically thin layers from the surface of materials in a controlled way. This technique is now very crucial for nanofabrication and semiconductor industry in orde

The purpose of this essay is to examine how the male participants of the Swedish version of Paradise Hotel express friendship and gain power. To answer the questions of issue, 8 episodes of the reality-TV show have been analysed through Norman Fairclough’s Critical Discourse Analysis. The theoretical framework is based on R.W. Connell’s theories regarding masculinities, Judith Butler’s theories re

Att använda råvaror och energi så effektivt som möjligt är en utvecklingsriktning som genomsyrar hela samhället. Ett resultat av detta är att nya regler och ny teknik har lett till att nya byggnader använder värme mer effektivt än tidigare. Då fjärrvärme står för drygt hälften av uppvärmningen i Sverige innebär en förändrad värmeanvändning nya förutsättningar för fjärrvärmens framtida utveckling.

The Normalized Vegetation Difference Index (NDVI) is frequently used as a surrogate for vegetation properties and is often correlated with climatic variables such as rainfall. However, studies have shown that conventional regression models used to study the spatial relationship between NDVI and rainfall are often plagued by non-stationarity and are scale dependent. This thesis employed a spatial d

Imaging in scattering media is used in different fields such as medicine for the diagnosis of tissues or in combustion to study spray injection systems. The problem with imaging in scattering media is the blurring induced by multiply scattered photons. There exists techniques to reduce multiple scattering detection, based on various filtering approaches. Two-photon excitation fluorescence imaging

Syfte: Studiens syfte är att undersöka om deltagarorienterat managementsynsätt och inre motivation har ett positivt samband. Metod: Studien utgick från en deduktiv ansats med en tvärsnittsdesign. Data samlades in via en webbaserad enkät som skickades ut via Sveriges Kommunikatörers nyhetsbrev. Enkäten bestod av två delar där Del I mäter huruvida kommunikatören motiveras av olika påståenden och dä

I Skåne står industrisektorn för omkring 26% av energianvändningen, och producerar samtidigt betydande mängder spillvärme. Det pågår kontinuerligt ett utvecklingsarbete och det finns redan många lyckade exempel på återvinning av industriell restvärme, men det finns fortfarande potential till förbättring. Som fallstudie har en medelstor kemisk tillverkningsindustri, som huvudsakligen producerar vat

In an attempt to at the same time introduce new technology into the existing public transport network, investigate the impact of this technology on street space in cities and present a solution to the problem with congestion in dense city centers a model is introduced. This model demonstrates one way to implement autonomous vehicles in the public transport network in dense city centers. The result

Klimatförändringen är en av vår tids stora utmaningar. Energieffektivisering och satsning på förnyelsebar energi måste ske på bred front. Viljan finns, men industrier och företag hindras av att verka i detta kvartalsrapporteringens tidevarv.

Image quality has always been a matter of great importance for anyone working with or consuming images and videos. Images and videos are, in general, for human consumption. Thus, image quality is essentially a subjective attribute of an image. Though there exist both objective and subjective approaches to assessing image quality, objective results may not correlate well with subjective result

Radar is a technology that is widely used in many diverse areas; from monitoring space down to ocean surveillance, with many more applications in between. The technology existed before, but was mainly developed in secret by several nations during World War II. Radar technology uses radio waves to detect various kinds of objects and can determine their range, velocity and orientation. It is, theref

Congratulations! You have a new match - a qualitative study about the meaning of clothes on Tinder is a bachelor thesis about how people can communicate via clothes on the dating application Tinder. This thesis analyses how clothes communicate and give a glimpse of the identity of the person in the images. Through Erving Goffman and his theory on roles in everyday situations the thesis analyses th

The purpose of this study is to understand and gain insights into the entrepreneurial marketing experiences of female immigrant women in the Helsinki metropolitan area. There is limited literature on immigrant entrepreneurs in Finland and even less regarding female immigrant entrepreneurs, thus it is important to investigate this subject matter. A qualitative research method is adopted, through t
