As more renewable and intermittent power sources are incorporated into the grid, the need for energy storage solutions increases. Implementation of hybrid energy storage solutions (HESS) could enhance system flexibility and contribute to the development of renewable energy systems. The purpose of this master thesis project is to investigate the technical and economic viability of different configu
Football, or soccer as the Americans call it, is the world’s most popular sport. Why is that? I believe it has something to do with the simplicity of the game. Compared to a lot of other sports, the only piece of equipment you need to play is a ball. With only a ball, a game of football could be played almost anywhere - in the park, at the beach, against a wall or on the street. One of the reason
Drying clothes is an essential but energy demanding process in modern society. A common way to dry clothes is tumble drying. Electrolux is one of the world leading manufacturers of household appliances and currently is working on a heat pump tumble dryer product. This master thesis is a study of the aerodynamic properties for the internal air flow for the mentioned heat pump tumble dryer. If press
Floods are expected to increase around the world due to climate change, and Scania is especially vulnerable with its elongated coastline and lack of postglacial rebound. Spatial planning has a key role in adapting to these changes and coping with the consequences. This report aims to map out challenges when dealing with flooding in the field of spatial planning in already developed areas and to pr
This study examines attitudes towards Swedish immigration and minority groups in Sweden among social work students and law students at Lund university. Firstly, this study examines if there are similarities and differences in attitudes among the students by using univariate analysis. Secondly, this study examines if there are any correlations between attitudes and the following variables: age, gen
Recent decline in wild pollinators have been reported and studies have found a connection to increasing urbanisation, larger homogenous landscapes and increased pesticide usage. The pollinators are important to preserve for various ecosystem services, such as plant reproduction, however the effects on pollination success has not been thoroughly studied in relation to urbanisation. In this study th
Most studies done on Drosophila are made in labs and focus on genetics, something which has formed a somewhat one-sided field of studies. To counter this bias, this report was based on fieldwork. From a classical ecological aspect, Drosophila populations in southern Scania were investigated in order to put more clinical Drosophila insights in a proper context. According to previous studies, urban
The Internet, which is the most important component of digitalization, has proved to be a useful, but unfortunately economically difficult channel for the news agency. The rapid shift of digitalization in the 21st century has changed the game plan for traditional fashion journalism. Editors have, through various strategies at the best of their ability, adapted to the new market situation and large
The fruit fly Drosophila melanogaster has a well-studied olfactory system. A crucial part of the olfactory system is the olfactory sensory neurons (OSNs). One type of these OSNs, Ab3a, expresses the Odor receptors (ORs) Or22a and Or22b. Or22a is known to play an important role for behaviors like oviposition, but no strong ligand has been found for Or22b. Recent studies have shown that D. melanogas
Applications based on Wireless Sensor Networks are making their way into all kinds of industries. Today, they can do anything from off-loading hospitals by monitoring patients in their homes to regulating production lines in factories. More often than not, they perform some kind of surveillance and tracking. Thus, in most cases the information they carry is sensitive, rendering good encryption sch
This thesis work was performed at Ineda System Pvt Ltd, Hyderabad, India. Pacman is an interrupt controller, designed with the concept of priority based selection of peripherals with 16x8 input interrupt lines. The main objective of this Master Thesis is to upgrade 16x8 interrupt controller and priority resolver to 128x8 input interrupt lines and adding a debug feature for this customised processo
Wing pigmentation in dragonflies and damselflies (odonates) functions as a secondary sexual trait with a role in courtship and antagonistic male-male interactions. Recently, a thermoregulatory function of wing pigmentation has also been suggested. This study aimed to elucidate how both sexual and natural selection have influenced the evolution and global distribution of wing pigmentation in odonat
Sponges are aquatic filter feeding animals that use internal chambers comprised of choanoflagellate-like cells called choanocytes to pump and filter water. In this study I investigated the behavior of choanocytes in juvenile Amphimedon queenslandica, a coral reef demosponge, when they were fed Photobacterium damselae subsp. damselae compared to when they were maintained in 0.22μm filtered seawater
Diploid potato cultivars that are propagated by True Potato Seeds (TPS) are a new potentially revolutionary way of potato breeding. Conventional breeding is based on highly heterozygous tetraploid potato varieties. Diploid potato breeding by TPS is useful to create inbred lines and from there hybrid offspring. TPS is cheaper, has almost no diseases and is easy to distribute. Diploid potatoes have
In this study, Global Positioning System (GPS)-derived tracking data were used to explore aspects of the breeding season movement ecology of an at-risk seabird, the Caspian Tern, in the Baltic Sea. In particular, the foraging effort, daily activity, and foraging habitat use of the terns were investigated at two breeding colonies. Data were collected during two seasons at the colony on Stenarna isl
SeqCapAnalyst is a pipeline to process .fastq files, producing the standard files as well as statistics useful for singling out good targets for Sequence Capture probes. Rather than speed, it is optimized for flexibility and ease of modification. SeqCapAnalyst is predominantly written in bash, with one module written in Python. The pipeline was tested on sequence capture data which was obtained f
