Grazemore DSS för att prediktera beteskvalitet för mjölkkor :
The aim of this study was to examine if the predictions of the herbage quality in the software Grazemore Decision Support System (DSS) gives a reliable ground for milk production in the north of Scandinavia.
Pasture samples from one research farm (Umeå) and one organic farm (Nordingrå) was analysed on crude protein and organic matter digestibility. The results were statistically compared to the predicted values. Measured and predicted herbage mass was compared and a control if the predictions of milk production improved if the predicted input were replaced by the values from the analysis, was made.
The concentration of crude protein was underestimated by the model on both farms and the relationship between actual and predicted values was poor. Mean Prediction Error (MPE) was 24% and 31% respectively.

Timmerkvalitet hos björk i blandskog med gran
Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).
Double integrating spheres: A method for assessment of optical properties of biological tissues
The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

Att studera validerade mätinstrument : för att mäta barns oro inför dagoperation
Background: Anxiety with children before surgery is well known. From the 1950s there are various assessment instruments. Despite that most day surgery units offer preparation for children and parents, there are many children who exhibit a strong anxiety the day of surgery, which can lead to postoperative behavioral changes. Today the nurse estimates the anxiety of a child on personal experience and knowledge, forming the basis for estimation whether the child is in need of sedation or not. The purpose: of this study was to evaluate instruments that the nurse can use in measuring the degree of anxiety of children before fast clinical settings, such as day surgery.
IPv6 - Inte längre frågan OM och inte så mycket NÄR utan snarare HUR!
Problemområde:
Idag har Internet blivit var mans egendom. Detta innebär tyvärr en hel del
problem. Det tydligaste vi står inför idag är att IP-adresserna håller på att
ta slut. För att bli av med problemet används olika temporära lösningar
("lappningsteknik") men även en permanent lösning utvecklas, nämligen Ipv6
(Internet Protocol version 6).Det nya protokollet löser adressbristen men har
även många andra funktioner så som säkerhet och bättre routinglösningar. Vi
ställde oss då frågan varför har ingen övergång skett trots dessa fördelar.
Frågeställning:
Var i övergången mellan IPv4 och IPv6 står vi idag? Varför har inte övergången
mellan IPv4 och IPv6 redan skett? Vilka är de största anledningarna och vilka
fler möjliga finns det?
Slutsats:
Arbetet visar att tiden för en övergång ännu inte är inne.
Sammanställning och produktion av ritningsunderlag till båt
Hanterbara båtar is a new company who builds alumina boats customized for people in wheelchairs. Due to the fact that the company only built two boats yet, the production documentation is not complete. The drawing that does exist is not in an exact standard which makes production planning harder.The purpose of this work has been to make the production of the boat easier and simplify further development and modification. Product development in the form of optimizing details is also one of the main purpose of this work.This is all done by making a 3D-assembly of all the existing drawings. After this is done new drawings will be made and added to the main assembly.
Vitpunktsförskjutningens påverkan på ICC-profiler vid användande av optiska vitmedel
The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point.

Furthermore, the aim of the study is to examine how temporary agency workers perceive their psychosocial work environment, and possible consequences of such perception. The methodology of the study consists of practical legal method and qualitative method in the form of interviews.The results show that the psychosocial work environment for temporary agency workers is regulated at both the EU legal level by Directive as well as at national level in Arbetsmiljölagen and regulations issued by Arbetsmiljöverket. The study finds that health and safety responsibility for temporary agency workers is shared between the agency and the client company. The result of the study indicates that there are shortcomings in the introduction and training of temporary agency workers, which can contribute to an unsatisfactory work environment.
Kundrelationsarbete i den industriella försäljningsprocessen
The purpose of this thesis was to examine how the build-up of customer relations can be characterized at the end of the industrial selling process and how companies engage their cross-functional selling teams into this relationship building effort. Through a case study of Omega, a multinational company engaged in the selling of products of an industrial character, it was revealed that the build-up and maintaining of the customer relationship is of acute importance, as it presents the company with a window of opportunities. Through its relationship with the customer the company can be able to sell other products, which are related to the original purchase made by the customer. For the company?s competitors the established relationship might also serve as a barrier when attempting to enter the market or increase market share.
Analys och förbättringsförslag för riktkopplardesign
Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.
