Modellerade och uppmätta kväveflöden i energiskog som bevattnas med avloppsvatten
The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

Excel-baserad beräkning och dokumentation av distansskyddsinställningar
This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.
Re: Yarning
From a social perspective, I have been working on how to change current consumption patterns through a change in people's behavior and attitude towards their possessions. The concept is based on how we can value, care for, and preserve our belongings by using theories in the empathic design field. I have created a structure that allows people to become an active part of a creative process and create their own products. Through this commitment, an emotional relationship is built between the user and the product, and the product tends to gain a longer life. Based on a method to manufacture your own yarn by reusing old clothes, I want to provide the basic tools for an easy and playful way to build the knowledge needed to produce something useful..
Implementation av prototyp för inomhuspositionering
Utveckling av teknik skapar ständigt nya möjligheter men innebär också stora förändringar för företag och organisationer. Mobiltelefoner, surfplattor, bärbara datorer, mobilkommunikation och molnteknik gör det möjligt idag att inte längre vara bunden av tid, plats eller en enhet för att kunna arbeta. Förändringen innebär att en ny typ av flexibla och yteffektiva kontor med inga fasta arbetsplatser blir allt vanligare. Problemet med de så kallade flexkontoren är att veta var eller när en kollega befinner sig på kontoret är inte lika självklart, framförallt om det är stort kontor med flera våningsplan.Målsättningen med detta arbete är att ta fram och implementera en inomhuspositioneringstjänst eller en så kallad Location-Based Service, till företaget Connecta AB. Tjänsten ska göra det möjligt för användare att med hjälp av sin mobiltelefon dela med sig av sin nuvarande arbetsplats i en kontorsmiljö.Resultatet av arbetet är en Location Based Service som gör det möjligt för en användare att med hjälp av en Androidtelefon med stöd för kortdistanskommunikationstekniken Near Field Communcication att dela med sig av sin nuvarande arbetsplats.

Framtagande av kravspecifikation för standardsystem
There are several methods and models within the areas of software engineering
on how to proceed during a software development process. For each of these
methods and models there are benefits and drawbacks, depending on how you
choose to look at them. A difference of principle between the different models
is that they either advocate iterative development or not.
In parts of software engineering one makes use of different methods depending
on which is most fitting in a specific situation. There are several methods on
how to recieve more qualitative data from the end-users during the requirement
collection, but the reappearing pattern is still user centric participation,
which means that the user participates more actively in part of or the entire
development process.
Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :
The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.
Vinstdelning: En studie i hur affärsjuridiska advokatbyråers vinstdelningssystem är uppbyggda och hur valet av vinstdelningssystem påverkar organisationen.
In the last couple of decades, corporate law firms have rapidly grown to become both influential and highly profitable corporations in the business world. Today, the largest law firms are assumed to bear far greater resemblance to large and often multinational public limited companies than the small businesses generally associated with legal services. However, one interesting specific set them apart from the majority of other companies; the partnership and its interrelated profit sharing. The aim of this study has therefore been to investigate partner compensation systems in corporate law firms and further examine what implications chosen compensation systems have on the organizations. Using a multiple case study, including 7 of Scandinavia?s largest and most well known law firms, the results show that partner compensation systems are highly individual and the critical question is whether to employ seniority based or performance based compensation systems.
Konst eller pedagogik?: Nutida dagspresskritik av bilderböcker
The aim of this study is to examine views of picture books for children that reviewers in Swedish daily press express in their reviews in 2009 and 2010. The following questions were posed in the study: Are picture book reviews based on pedagogical criteria and/or aesthetic/literary criteria? Are picture books reviewed from an adult perspective and/or from a child perspective? Which elements of positive and negative criticism are to be found in picture book reviews? This qualitative study is based on 45 reviews of picture books in Swedish daily press. The theoretical approach is developed from four ways of looking at children literature that professor Maria Nikolajeva has compiled. The method used is idea analysis, which is a form of text-analysis.
