-A study focusing on the voltage fluctuations and symmetry at the one- and three-phase connections of photovoltaic systems.

One problem with the Swedish railways is the low reliability and punctuality. A distinction can be made between major and minor disorders, where minor disorders have a greater impact on overall punctuality because of its large numbers. One way to describe the large disorders are with punctuality dips and punctuality depressions, which are short-term and long-term variations in punctuality. This st

Prevas has in its customer contracts had a need for a simpler general manager for process recipes which send recipe parameters (eg rotational speed of a mixer or temperature in a furnace, etc.) to a Programmable Logic Controller. Software for this is available on the market but are either too complex or costly. To solve this problem a Windows service was developed. This report briefly describes ho

Målet med uppsatsen är att studera hur en välfungerande kallelsemall kan se ut samt att studera processen att ta fram en ny kallelse. Metoden som används är textanalys med kritisk diskursanalys som teoretisk ram. Två mallar för kallelse till cellprov har analyserats – en äldre version från region Stockholm Gotland samt en ny nationell cellprovskallelse. Analysen av språkhandlingar, attityder, närh

Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. In particular, scientific research is very active to find technologies that increase the efficiency of the solar cells, or decrease their cost. Reducin

Bildbehandling av mitoser i digitala patologibilder I digitala bilder av vävnadsprov finns en klar relation mellan celldelningar och cancer. Att avgöra om vissa strukturer är cellkärnor i delningsfas eller inte, kan vara svårt. Detta arbete avsåg bildbehandling av skärpa och kontrast för att underlätta medicinsk bedömning. Cancer är en av våra dödligaste sjukdomar. När cancer diagnostiseras tas Identifying mitotic figures in digital pathology images is useful in diagnosis and prognosis of cancer. The task itself is time consuming and sometimes difficult for pathologists. Recent research has focused on machine learning for automatic detection of mitoses. The aim of this work was to apply image processing to facilitate ocular examination of mitotic figures in hematoxylin and eosin stained

Ribonucleotide reductases (RNR) are key enzymes for transformation of RNA building blocks (NTPs) to DNA building blocks (dNTPs), an essential step in biological systems. RNRs are known to be the first enzymes identified with free radical chemistry and play an important role in having a tight control over dNTP levels, as these DNA building blocks are needed for vital cellular processes such as cell

Much attention has been paid to Indigenous gender ideologies and Indigenous women´s political participation in Latin America. The construction of gender equality and its implications for Indigenous women’s activism in Ecuador´s Indigenous movement is, however, widely undiscovered terrain. The purpose of this qualitative case study of CONAIE was to address this gap and connect the dots by asking: H

Chefer och ingenjörer på fallföretaget har olika syn på innovation, vilket resulterar i en diskrepans vad gäller synen på hur innovation bör ledas. I det dagliga arbetet efterfrågar ingenjörerna på fallföretaget autonomi. Huvudbidraget i denna studie består i att den visar hur efterfrågan på autonomi faktiskt förändras när det gäller innovationsprocesser, i denna specifika form av kontext efterfrå

Miljöcertifieringar är en växande marknad i Sverige där intresset och efterfrågan från hyresgäster ökar. Många fastighetsföretag har idag som policy att all nyproduktion och större ombyggnader ska miljöcertifieras. Mycket tyder på att miljöcertifieringar kan bli en framtida praxis i den svenska fastighetsbranschen. Certifieringar har flera ekonomiska fördelar som positivt kan påverka en fastighet

The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o

Considering the growing pressure on various ecosystems all around the world, the development of ecological indicators for assessing the health and condition of the ecosystems has become an integral part of environmental management and policy making efforts. Such indicators do not only simplify the complex ecosystem processes but can also act as a measure of performance of a conservation policy. Th

För att särskilja sig från konkurrenter investerar organisationer enorma summor i att koppla sitt varumärke till en viss färg. Vid skapandet av brand equity är brand elements så som logotyper en central del. Vilken betydelse har egentligen färg på logotyper och vad påverkar det utifrån ett varumärkesperspektiv? Syftet med denna uppsats är att utreda huruvida användandet av olika färger på logotypTo stand out from competitors, organizations invest large amounts of money to associate their brand with a certain color. In terms of creating brand equity, brand elements such as logos are of vital importance. What influence does the color of the logo have and what does it affect from a brand perspective? The purpose of the study is to investigate how the usage of different colors in logos affec

This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorit

En explosiv ökning av interaktiva webbttjänster gör att webb-tillgänglighet är ett hett ämne. Det syftar på att alla, oavsett funktionsnedsättningar, ska komma åt webb-innehåll. Företag med hundratals applikationer kan genom förbättrad till- gänglighet e ektivisera arbetsprocesser, spara resurser och rekrytera er.There is an explosive growth in on-line information and interactive services provided on the Web. Web accessibility refers to designing these websites so that all people, no matter disabilities, can access Web content. Recently in Sweden, laws and regulations have been imposed, requiring private corporations to ensure an accessible digital work environment. Scania is a major Swedish automotive ind

Purpose: Exploring the possibilities and critical aspects of mobile self-checkout to enhance value creation and customer satisfaction for physical retailer Research question: How can value be (co-)created between a big box retailer and its customers through a mobile self-checkout solution? Theoretical considerations: After the evaluation of the current literature in value (co-)creation, customer

The European Spallation Source ERIC is a new neutron spallation source being built in Lund, Sweden, with NMX as one of the pioneer instruments. NMX is a Quasi-Laue single crystal neutron diffractometer for the investigation of large biological molecules. Wavelength, size and divergence of the neutron beam reaching the sample have to be controlled to properly match the different experimental needs.

This thesis examines Ismaʿili individuals’ “lived religion” through personal views on religious values combined with daily practices in German society. Since a Eurocentric view on Islam often fails to recognize the complexities of Muslim communities while emphasizing the Muslim faith as incompatible with “modernity”, the current study of the Ismaʿili branch serves as an example of Muslim practices

Det här projektet ämnar fånga, och med matematiska modeller beskriva, beteendet hos försäljningen under en butikskampanj i en matvarubutik. Detta med hjälp av Artificiella Neurala Nätverk. Idag använder de flesta matvarukedjor så kallad datorassisterad beställning, vid beställning av deras butiksartiklar. Dessa system fungerar förhållandevis bra under normalförsäljning, men tar ofta inte hänsyn tThis thesis will investigate the characteristics and possibilities of implementing a forecasting model for campaign sales in Coop stores. The implementation will be done by the use of multiple linear regression and artificial neural networks. Advantages and drawbacks of these models will be investigated and discussed. The campaign characteristics will be evaluated using linear methods, and seve
