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

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

As female labor participation rates, educational attainment, and occupational prestige improve the colocational dilemma of migration increasingly a problem. This paper seeks to determinine the difference in determinents and outcomes of interstate migration across educationally homogamous couples in the United States. The paper uses data from the Panel Survey of Income Dynamics for couples, married

Lord of the Flies (1954) by William Golding is seen by many as a portrait of the violent darkness of human nature, and how all of humanity will revert to a savage state in the absence of civilisation. This essay argues that this is not accurate, since the book only presents the actions of a group of British boys, among which the majority of the violent acts are performed by boys who are most likel

Designing an energy-efficient building with the use of passive design measures is not always possible due to the location, surrounding buildings or site layout. This can result in larger façade areas facing East or West and causes issues with the low sun altitude. The sun can thereby not be blocked constantly, since daylight is needed for the well-being of students and improves their study perform
