Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS
This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.
Tre metoder för diagnos av mastit i fält :
The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings.
DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations.
Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

Shaping visual stories - content in exhibitions is an essay on how content has been shaped in the two exhibitions "Memento mori" and "Hästen - tyglad, piskad, älskad". The study focuses on how exhibitions can be defined through their content as well as how the exhibitors'different intentions towards the exhibition affect the working process as well as the result. This is put in relation to theoretical models and discussions on ideals in the field of exhibition and what impels these to find an answer to the question: What makes an exhibition?.
Ett hindutempels verksamhet och funktion i diaspora : En etnografisk studie om ett swaminaryantempel i Mellansverige
This essay has been investigate a Hindu swaminarayantempel in central Sweden, its activities and function from a diaspora perspective. Also to investigate the relationship between Hindu diaspora groups and in relation to South Asia. An ethnographic method was used.The result of this study shows that the key activities temple provides the puja. Pujan is the most frequent activity in the investigated Temple. The temple also provides other activities that often are linked to anniversaries and celebrations of festive calendar, such as Diwali or gods' birthdays.The investigated temple has a similar function as other diaspora groups.
Noggrannhet vid målinmätning : Analys av ett eldledningsinstrument med förbättringsförslag
This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.
Nekande tvångsmakt i Operation Unified Protector
There are several competing views on how to best utilize air power. Following his quantitative study of air power, Robert Pape developed a theory which focuses on undermining the target state's military strategy. According to Pape it is possible to explain the outcome as a result of military vulnerability. This essay seeks to determine if Pape's theory can predict the outcome of Operation Unified Protector. By using a mixed methods approach on four hypotheses, it will be determined if the operation was a successful case of coercion, if NATO acted according to Pape's model and whether this achieved the desired effects or not. The results reveal that the theory could not successfully predict the outcome of the conflict.
Diskkrypteringsprestanda i GNU/Linux
This thesis compares the impact on disk performance in a GNU/Linux environmentwith three encryption algorithms: AES, Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that is drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..
Storage stability in a milk based UHT-beverage : effect of pH, carrageenan and storage time
The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common
defect in these type of products.
Interkommunal IT-samverkan. Faktorer och effekter av ett framgångsrikt samarbete
Today more and more municipalities interact across a wide range of sectors. The reasons tostart interacting are varying and for those who succeed with this form of work, there arebenefits in terms of efficiency and knowledge exchanges. But are the reasons that interactalways obvious? Sweden currently has 290 municipalities of varying size and allmunicipalities have basically the same mission, to deliver services to its residents.Information technology allows municipalities to digitize much of the workload, but theintroduction of the technique is not without problems. For small municipalities, there are greatdemands to deliver reliability and support for their internal and external services.

Derivativ talan och Corporate Governance. En komparativ studie ur ett rättsekonomiskt perspektiv
The world is getting smaller. Global markets, political processes and communication technology bring people together. Even though many of these processes are dynamic and constructive, they have also resulted in a need for better and more effective ways of international conflict resolution. This thesis investigates central issues connected to the concept of humanitarian interventions in relation to current and future legislation of the European Union. The overall question is whether the rapid globalization process has resulted in a change of international law towards more liberal view where authorization of the security council is not always needed? And, if there has actually been such a liberalization, how does that affect the legal possibilities for the European Union to carry out armed operations without the consent of the global community?The conclusion of the thesis is that international law has been modified mainly in two aspects: First, the concept of sovereignty is no longer seen merely as a right of the nation, but also as a responsibility.
