Effektivisering av kvävereduktionen i en konstruerad våtmark avsedd att behandla avloppsvatten
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A Comparison of theoretical data of different WES-based terrain interaction models and a Comparison test data from a full scale field test is presented.
"Jag blev intresserad av matte" : Ett aktionsforskningsprojekt med formativ bedömning i matematik
This thesis examines the implications of a shorter intensive action research project on the formative assessments key strategies four and five that are activating learners as learning resources for one another and activating learners as owners of their own learning. The research questions were ?How do the pupils experience the formative approach?? ?What didactic consequences does the formative approach mean for the role of the teacher?? and ?How does the formative approach affects the pupils? results on a short term??. The results were that the majority of the pupils liked the approach and that they felt like their efficiency increased. The didactic consequences were that the teacher had to spend more time on evaluation but had more time during the lesson to listen to and discuss with the pupils. The pupils? results were not changed in Comparison with the control group..
Belöningssystem för anställda: Når de upp till ledningens mål?
Purpose:
The purpose of this paper is to examine if companies? incentive programs for
employees is designed in such a way that it makes it possible for managers to
reach their goals.
Method:
Qualitative with a semi standardised questionnaire
Results:
Our results is that the incentive programs for employees in their present form
don?t give the companies a good possibility to effect the employees to perform
towards the goals of the system. The performance measures in the incentive
programs for employees is suitable in Comparison with the goals of the program
but the construction and the use of the systems doesn?t give a satisfied result
in comprising with the goals.
En Fallstudie av Implementeringen av EU:s Minoritetsskydd
The intention of this thesis in political science is to understand how the European Union fights and prevents discrimination against the Roma minorities in Sweden and Romania, and how the implementation works in reality. The study consists of defining what it means to be objectively discriminated, what ethnicity really means and how the implementation process consist of a Comparison and statement has been made by the national governments and comparing how two socioeconomically different member states handle EU directives and implement them in Sweden and Romania. The main findings of this study was that EU policies lack the capital and explicitness that is needed for great results to be accomplished and that the governments in both countries have different issues with implementing the protection of the human rights and Roma culture, and that EU needs to be more practical and develop in a faster pace. .
Missilstyrning med Model Predictive Control
This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
Visuellt jämföra filmtrailers med hjälp av matlab
The primary intention of this paper was to visually compare film trailers without considering semantic information, through use of a self-developed Matlab program, resembling that of human perception. Circa 150 people participated in an online survey where they were shown two film trailers and asked to rate their visual similarities. The result from the program was weighted against the survey results in such a way that the weights corresponded to a 75% accuracy between the program?s and the participant?s (for participants with prior experience in the field of photography and/or film) Comparisons.How accurate can we compare still images from film trailers, and find similar trailers for the human viewer, by analyzing saturation, color tone, contrast and lightness with a self-developed Matlab program..

Vad påverkas odlarna av i den svenska morotsodlingen? :
In this degree project I write about how the farmers who grows carrots in Sweden get
influenced by different rules, investments and demands. The Swedish agriculture are
heading towards a harder time, and then you have to find new things to do. Now its
hardly no profit to grow grain so you have find other crops. This paper is not a
Comparison between the contract cultivation to Findus and the cultivation where the
farmer maked his products by a own company on the farm.
If you have a small processing company on the farm, you have to increase the
standard with different certificate. The farmer binds a lot of capital in machines, both
field and in the process.

Fiende utan ansikte - en jämförande studie av terroristgrupper under efterkrigstiden
AbstractThe purpose of this theses is to compare three different political groups, The IRA, The Baader-Meinhof group and the Al Qaida, who have all used terroristic methods to achieve their separate goals.By finding out about their history, goals, structures and methods I have made a Comparison to see what joins them, what separates them, what originated the birth of their movements and how they can or could proceed with their violent actions to the point that they had actual impact on international politics.It has all been done through a litteraturebased study.My focuse has been on Al Qaida since it's is the only one of the three who is still active today and who, through its cellstructure, represents a new form of global terrorism that may have great influence on the structural patterns of other political groups and criminal organizations in the future.Key words:Al QaidaBaader-MeinhofIRATerrorismCellstructure.
Den offentliga upphandlingens påverkan på entreprenörer : En studie av små och medelstora byggentreprenörer
Public procurement in Sweden is regulated by the Act on Public Procurement (lagen om offentlig upphandling, LOU, in Swedish). The Public procurement in Sweden stands every year approximately for 500 billion Swedish crowns of the taxpayers? money. It is therefore important that the money is spent in the best possible way. The focus in this study is set on the relationship between the small- and medium sized building entrepreneurs and the government.
