The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

This study departs from Gállok, an area 40 kilometres northwest of the city Jokkmokk, in northern Sweden. This is a place to which local people and Saami reindeer herders have material interests and emotional bonds. The mining company JIMAB wants to prospect for extracting minerals from this area. In the summer of 2013 local people, Saamis and environmental activists gathered in Gállok in order to protest and make resistance against these plans. Activism was made, debate articles were written, demonstrations were organized and information about what was going on in Gállok was shared through social media.The aim of this study is to examine the cultural processes of the anti-mining movement, in particular the happenings in Gállok in summer 2013.

Syfte: Uppsatsens syfte är att undersöka huruvida det går att skapa överavkastning påden svenska aktiemarknaden genom att använda sig av strategin 52?week highmomentum. Uppsatsen syftar även till att undersöka huruvida eventuell överavkastningkan härledas till bolagsstorlek. Metod: Aktierna i dataurvalet rangordnas i förhållande till sina årshögsta. Portföljenkonstrueras genom att gå lång i de 30 % av aktierna som ligger närmast sitt årshögstaoch gå kort i de 30 % av aktierna som ligger längst ifrån sitt årshögsta.

The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.

To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.
