Processuell generering av oändliga spelvärldar : Praktiska problem och optimering
Enligt oss så är det största problemet med att processuellt generera en pseudo-oändlig spelvärld i realtid är att få genereringen att ske så sömlöst som möjligt samtidigt som världen upplevs som konsekvent. För att finna lösningar på detta problem så analyserar vi andra studier och spel som utnyttjar processuell generering. Vi använder sedan de metoder och tekniker vi funnit för skapandet av en egen applikation för att få en djupare förståelse för hur dessa fungerar i praktiken och hur mycket varje metod påverkar prestandan. I vår slutsats beskriver vi de problem vi fann, deras orsak och ger förslag på lösningar. På grund av studiens tekniska karaktär så riktar den sig främst till programmerare.
Avblås för torkning av kabel
This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.
Passivhus med prefabelement : En jämförelse mellan en platstillverkad konstruktion och prefabelement från Masonite Lättelement AB
This thesis conducted at the University of Uppsala investigateshow well a prefabricated building component from the manufacturerMasonite Lättelement AB can be incorporated into ahouse projected to accomplish the demanding criteria of a passivehouse. The thesis is organized as a comparison betweenthe prefabricated elements and an on-site built component fromthe passive house area of Oxtorget in Värnamo, Sweden. Theaspects investigated were air leakage, energy, moisture, economyand noise conditions.Results of the comparative analyzes shows that the prefabricatedproducts were capable of accomplishing the requirementsof passive houses and therefore this thesis should beviewed as a basis to confirm that the technology of prefabricatedbuilding components today in Sweden are mature enoughto be a significant part of the passive houses that are to be builtin the near future. The development of prefabricated technologyis of crucial significance if we are to accomplish the goalsof reduced energy consumption by the year 2020..
Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

?Roll up! Roll up for The Magical Mystery Tour!? : om upplevelseindustrin i The Beatles Liverpool
During the 19th centaury Liverpool was an industrial city of great magnitude owing to the well-established communication and infrastructure in the area. During the 1950?s the industry decrease swiftly - and although Liverpool as a city gain interest as a result of the sensation of the Merseybeat and The Beatles - the reduction continued through the 70?s and during the 80?s the people of Liverpool suffered from great unemployment. Today Liverpool is a post-industrial city with a growing experience economy that mainly benefits from The Beatles tourism and the Merseybeat-era. The focus of these studies is the experience economy in Liverpool as a result of globalization and production in the late modernity.

De akustiska skillnaderna mellan två städer i Sverige
Studien bygger på två 24 timmars ljudinspelningar utförda från två olika städer iSverige. Syftet med undersökningen var att se om det gick att urskilja akustiskaskillnader mellan två olika städer i Sverige. Studien har tagit mycket inspiration av R.Murray Schafer arbeten inom soundscaping, samt Pijanowskij, et al., (2011) ramverkför att kunna kategorisera ljuden utifrån dess ursprung och funktion. Olikaundersökningar har genomförts med hjälp av kvalitativa intervjuer, samtfrekvensanalyser av det inspelade materialet. Båda metoderna användes tillsammansvid utvärderandet av ljudmaterialet för att se hur vida informanternas svaröverrensstämde med den frekvensanalys som genomförts.
Visstidsdirektivets implementering i svensk rätt : Har korrekt implementering skett?
The essays main intent is to examine whether there has been a proper implementation of the Council?s directive 1999/70/EG into Swedish law regarding the requirement for measures to prevent the abuse of successive fixed-term employment contracts. To achieve this purpose there is a need for an examination of current law. The essay also has some secondary purposes. One of these secondary purposes is the question of whether the implementation of the Council?s directive 1999/70/EG has lead to a reduction of the workers employment protection, which is closely connected to my main question and the violation case.
