Hur inverkar kontrollbordet på frekvenskurvan vid lyssningsposition i kontrollrummet när placeringar av högtalaren och lyssningsposition placerats efter ITU-R BS.1116-1 rekommendation?
The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.
Korruption i Estland och Lettland, en jämförande studie
Since the breakdown of the Soviet Union, more than fifteen revolutionary yearshave passed. Estonia and Latvia have undergone a change from communist statesto members of the European Union. As in so many other post-communist statescorruption has been a problem. However, Estonia has since the independence hada lower degree of corruption than the neighbour country Latvia. The main purposeof this thesis is to explain why so.
Den tvåfaldiga mångfalden - en postkolonial dekonstruktion av mångfaldsdiskursen
The purpose of our master?s thesis is to study the diversity discourse, used in Sweden, particularly the so-called ethnic diversity at the work place discourse.Our aims are to map and analyze the conceptualization of difference used in the diversity rhetoric. We intend to pursue our aim by studying the rhetoric of diversity, used for diversity promotion in the private and public sectors. Also, we will investigate into what conceptualizations of difference are used in the organizations in the name of ?diversity?.
Hur väljs spelfilm? Urvals- och inköpsprocessen hos Bibliotekstjänst samt urvalsprocessen hos svenska folkbibliotek
The main purpose of this thesis is to examine the process of selecting films at Bibliotekstjänst and at Swedish public libraries. The tools that have been used for analysing and interpreting the results from the interviews and the questionnaire are theory-based models describing the selection process concerning film and Carl Gustav Johannsen?s quality definitions. The result of the investigation shows that Bibliotekstjänst doesn?t really work with any quality definitions in their selection process.
Effekter av upphörd hävd i Lurö skärgård : Har diversiteten av kärlväxtarter förändrats?
One of the main reasons for the massive loss in plant species diversity is the fragmentation of habitats. In Europe, open pastures and meadows are the habitats going through the most changes during the 20th century, according to the agricultural changes. In this study vascular plants were invented at five different islands in the Lurö archipelago, Vänern, Sweden. The aim of the study was to sort out whether the diversity of plants has gone through any changes in abandoned managed grasslands compared to continuous managed grasslands. The aim was also to study if a change in the landscape has made any differences for the species development or decline.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Överlevnadsanalys och avyttringsorsaker - för ackordhäststiftelsens hästar 1967-2012
Few scientific studies have studied the subject of longevity among horses over a longer period of time. The knowledge about the Swedish riding school horse population concerning injuries and diseases is insufficient. Generally speaking, riding school horses in Sweden have a more undiversified way to work and work more hours in the arena compared to privately owned horses that have more variety in their possible use. Statistical data from the insurance company Agria have shown that horses in riding schools and education facilities have 22 % higher risk to use their veterinary insurance and 79 % higher risk to be put down and use their life insurance, compared to horses in private care. To create an increased understanding for longevity is it important to have knowledge about the different causes of culling.
The aim with this study is to increase the knowledge and enable problem solving within the subject of longevity, median length of life and causes of death.
INTERAKTION I EN VIRTUELL GRUPP : gapet i det normbildande ramverket
The existence of social networks on the Internet is today seen as broad, and the number of users of the network is increasing. There seems to be many reasons to which people are using the social networks. Within the network, users can for various reasons create groups with different objectives. One of the reasons is that groups are created in order to influence a company. With a perceived feeling that companies handle the problem differently, we assume the source is the uncertainty about what the groups really are.
Locally produced pork ? Västra Götaland
The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed.
Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.
Citizens United : - en strid mellan yttrandefrihet och politisk jämlikhet?
Modern democracies rest on a foundation of values essential to their prosperity. Two of those values are freedom of speech and political equality. To many, these values appear to coexist effortlessly. However, what this thesis aims to expose are some of the problems that quickly arise when attempts to interpret the values fail.The thesis investigates a specific US Supreme Court ruling called Citizens United. The ruling enabled corporations and unions to use their own treasuries for unlimited independent political expenditures.
Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnad i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat system
In this study, pollen contamination (measured by the number of seeds pollinated by pollen not belonging to any of the clones on the seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) seed orchard called Västerhus, located outside Önsköldsvik. In this seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 seeds from each tree.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations
The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.
Studenters val av bank : demografiska skillnaders påverkan på konsumentbeteenden vad gäller banktjänster
Students today, in the banking system, are the least loyal group. Students are also the most costly group due to the large investments, made by the banks, for them. Banks have generalized all students in one category and have adapted their offering regardless of students? social statues. As the students banking needs are dependent on their position in their lifecycle, generalizing them in one group is not optimal.The aim of this thesis is to investigate those factors which influence students? choice of bank.
En utmanad världsordning- En analys av nya och traditionella biståndsgivares idéer och intressen i det internationella utvecklingssamarbetet
In the past years the traditional donors of development assistance have been increasingly aware of changes in the donor landscape. This as emerging economies like China and India has undergone a transition from recieving aid to becoming emerging donors. By identifying and comparing ideas, beliefs and interests pursued using foreign aid between so called emerging and traditional donors, the greater purpose of this thesis is to take a closer look at the alleged changes in the world order. The starting point is Goldstein & Keohanes framework of the impact of ideas and interests in foreign policy and the one of K.J Holsti about institutions as markers metrics of change. The results show that there is no vast difference in interests but a detectable difference in the ideas behind foreign aid.
