Modern wireless technologies strive to meet users' ever increasing demand for high data rates and improved services. One of the most important constraints in wireless system performance is interference. More specifically, the interference caused by serving multiple users in the same geographical area can degrade the link quality greatly. A possible solution to the aforementioned problem it to
Syftet med denna studie var att undersöka om det kommunala projektet "Energijakten" har motiverat grundskoleelever att agera mer energibesparande. Studien undersökte även elevers upplevelse av skolans pedagogiska stöd till energibesparande beteenden. Self-determination theory användes som teoretisk utgångspunkt för studien. En kvasiexperimentell design användes genom att jämföra en skolaThe purpose of this study was to investigate whether the municipal project ”Energijakten” have motivated elementary school students to act more energy conserving. The study also explored the students’ experience of the educational support regarding energy saving behaviors. Self-determination theory was used as a theoretical framework for assessing motivation and educational support. A quasi-experi
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
