Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

Idag domineras en stor del av revisionbranchen av fyra stora revisionsbyråer. Det finns forskare som hävdar att revisionsbyråer och då främst de stora byråerna ägnar sig åt prispress av revisionsarvodet, så kallad low-balling, för att locka nya klienter för att sedan ta igen på intäkterna från konsulttjänsterna. En viktig aspekt att undersöka har varit vilka faktorer som påverkar prissättningen av revisionsarvodet då flera studier visar på att ett lågt revisorarvode är av betydelse för klienten. En stor del av den existerande forskningen behandlar amerikanska förhållanden, dock saknas det forskning de svenska förhållanden. Med denna bakgrund väcktes ett intresse att utföra en kvalitativ studie inom den svenska revisionsmarknaden.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

This essay is about the market of traditional rental movie stores, which today are on a mature stage of the marketing cycle. The technique is constantly accelerating and contributes to evaluation of new ways to watch movie. New competitors are such as bigger chain of stores that can offer, in addition to their wide range of other goods, rental movies as a secondary selling. The substitute is of most part Internet based services from where you can watch movie online or download film legally as well as illegally.These different sorts of new competitors or substitutes become a big threat on the traditional rental movie stores as these substitutes can offer the same prices or even lower.With these new ways of watching film this will on turn change the behaviours of the customers that likes to watch movies. The problem for the traditional rental movie stores is trying to keep their existing customers and try keeping them loyal to their store, so that they won?t loose them to the competitors and substitutes.

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.

Sweden?s health care is continuously subjected to economical cutbacks, which results in enormous workloads. To prevent problems that arise in these situations, it is of great importance to take measures to increase the efficiency of the working process. This goal can be obtained by increasing our knowledge of the body, under both normal and sickly conditions. That is, by sharing knowledge of the various medical service units within Stockholm?s county council and thus elaborates diagnostics.
