Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning
This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

Bredspridning av grönmassa :
There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.
Kulturen bakom kulturen - En komparativ studie av kultursynens inverkan på tyska och svenska kulturpolitiska strukturer
This thesis aims to develop a theory in the under researched field of international comparative cultural policy studies. lt does so by combining theories from the fields of political scienceand cultural studies, researching how and to what extent the concepts of culture of different states have an impact on the way cultural policies are constructed.The thesis uses this theoretical development in order to research a specific problem, namely the perceived possibility that Swedish and German cultural structures are slowly converging. Two recent official policy documents from each country are the objects of study. Through comparative idea analysis and with Michiel S. D Vries theories on decentralization, the thesis explains the convergence between the countries by differing cultural views between them.

Projektering av passersystem : En studie i användarstöd vid offertarbete för ARX passersystem
To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..
Dimensioner. Mellan 2D och 3D, en undersökning av yta och innehåll
A project exploring the boundaries between 2D and 3D. What is surface and what is substance? A countinuation of previous projects where I?ve examined the journey from two dimensional paper to three dimensonal objects. This project deals with the journey from three dimensonality back into a flat two dimensional surface, and the question if something can be both 2D and 3D at the same time. I decided not to center the project around a specific item, but rather let the project itself be in focus.

The Intellectual Capital Statement facilitates the mapping of interdependent and simultaneously impacting intellectual capital factors in a unique way. The process-orientation of the German approach differentiates it from its predecessors and gives an advantage over alternative procedures. By combining these aspects with the possibility to communicate the company?s efforts and progress in the field of intellectual capital, the German Intellectual Capital Statement (Wissensbilanz) provides an effective management tool..
Branding för distansarbetande kreatörer : Förbättra din nätnärvaro
In the fragmented network economy of toady remote work for creative designers becomes mor eand more prevalent. This is good for a number of reasons. Mainly, creative designers can find work inside and outside of their region irrespective of where they choose to live. However, competing for jobs in a global market is harder, and the online presence of the creatives becomes their main shopping window. We have conducted a study, interviewing digital creatives in Västerbotten.
Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap
In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..

Quadrotor UAV : Konstruktion och användbarhetsstudie av en UAV i sensornätverk
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.
