At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

A great deal of the nature experience we get today is from travelling along our roads, which to a large extent go through the forest landscape. This makes the forest along our roads interesting to look at from a nature experience perspective. The main idea of this work is to increase the awareness of how we are affected by the forest when we travel through it and find out how the forest should be adapted to the road environment to create a pleasant nature experience as well as increase traffic safety. 0.9 % of Sweden's total forest area (equivalent to 200 000 hectares) is in close proximity to roads. Additionally, in Sweden 440 million hours are spent behind the wheel of which a great deal probably is spent on roads surrounded by forest in some form.

The purpose of this paper is to investigate if a dynamic investment strategy on the Swedish asset market can accomplish better returns then a static investment strategy. The dynamic investment strategy is created by incorporating business cycle predictors and firm-level variables to predict future stock returns. The predictive regression is calculated wih 60 months of observation (1999 01-2005 12) and is then used to estimate future returns for 23 months in the period 2004 01 -2005 11. The structure of the regression, with linear functions of ? and ?, goes back to Shanken (1990) and Avramov and Chordia (2005) has had success with the variables chosen.

Road safety is the result of measures to reduce therisk of accident and injury. (Nationalencyklopedin,2008). In principle, road safety means to arrive saveand sound.Safe traffic in cities is mainly achieved throughappropriate speed. In Sweden, more than half ofall rides happen with a speed above the legal speedlimit (Holmberg, Hydén m.fl, 1996). To reducespeed in order to increase safety requires measureswhich influence a driver?s motives for his orher choice of speed even if these are not rational(Boverket, 2002).

Abstract The technology has made it possible for you as a train traveller to be available in other places than stations and on the train. You now have the possibility to communicate by the phone or through the Internet to get information about the train you want to take. Development in mobile technology gives us new possibilities to communication. We want to find out whatever SMS would be a suitable approach to inform passengers about delays. The problem formulation is ?If the technology is available to inform the passengers about delays in an more effective way than today, then why not use it? The ?Kustpilen? that operates in Blekinge and Skåne is the case for our study.

A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Syftet med denna studie var att undersöka lärares uppfattning om utomhuspedagogik och erfarenhet av att undervisa i utomhusmiljö. Respondentundersökningen utgick från de fyra frågeställningarna: Hur uppfattar lärare utomhuspedagogik? Vilka erfarenheter har lärare av att undervisa i utomhusmiljö? Hur uppfattar lärare elevers lärande i utomhusmiljö? Är det ett effektivt lärande som lärarna beskriver utifrån David Kolbs ?The Experiential Learning Cycle??Kvalitativa intervjuer användes som metod och genomfördes på tre olika grundskolor i mellersta Sverige. Den ena skolan har en miljö/naturprofil, de två andra skolorna har inte en miljö/naturprofil. Det insamlade materialet bearbetades med hjälp av en tematisk analys, samt utifrån David Kolbs erfarenhetsbaserade cirkel ? ?The Experiential Learning Cycle?.I studien redovisas lärarnas uppfattningar och erfarenheter, resultatet visar att lärarna uppfattar utomhuspedagogik som ett praktiskt arbetssätt där lärandet blir konkret.

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.

The work examines geographical variations of bicycle use in Trondheim municipality with the aim to create an understanding of what influences the use of bicycles and explain the geographical travel pattern for cycling. The work focuses on the how physical structures generates different transports effects. Where bicycle travels in Trondheim municipality are undertaken is described by using network analysis in ArcGIS, based on aggregated data from the travel habit survey (RVU) in 2009/2010. Trondheim municipality is divided into smaller geographical units (zoner) whose characteristics are described by 19 variables, categorized into 6 groups; Distance, Land use, Topography, Bicycle Facilities, Road characteristics and Demographic factors.By linear regression analysis in SPSS and ArcGIS Spatial Analyst, an explanatory model is elaborated. The variablesdistance to the regional center, workplace density, percentage separate bike paths and hilly terrain explains 78 percent of where cycle journeys are undertaken.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.
