Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.
Travhästars aktivitet i hagen
Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses.
The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.
The Capital Structure Puzzle of SME's - Evidence from the Swedish Security Industry
The purpose of this thesis is to ascertain the main determinable factors of Swedish SMEs capital structure decisions and to investigate whether existing capital structure theories are applicable on Swedish SME financing. We have used panel data to run regressions of various capital structure determinants on three measures of capital structure; short- term debt, long-term debt and total debt. We found that growth opportunities, profitability and age are the most important capitalstructures determinants for our sample. Firm size shows a small explanatory result but the effective tax rate and the asset tangibility do not seem to explain the capital structure at all. Thematurity matching principle is considered significant..
Elever som hänger med : en kvalitativ studie om skolsituationen för elever som enkelt klarar skolans uppnåendemål
The purpose of this research has been to find out whether and how teachers stimulate and motivate well achievers in the elementary school to reach a higher level. To gather information I visited two different schools within the same county in Stockholm and on each school I met and interviewed with two teachers. The answers received from these interviews are presented in this study as my results. I found that the teachers feel that students that do well in the classroom many times work as role models for the other students. Often these students require extra material as they usually finish their workload ahead of others.
En undersökning av Quicknets Customer Relation Management
This report is focused on a research to find out if the Customer Relation Management (CRM) of Quicknet AB works and if their customers are satisfied with it. During this investigation I tried to see if the customers had a need for taking the CRM and use a tool called Social CRM. The report will conclude if the clients of Quicknet think that there is something that can be done in the relation between both parts and how it can be improved. At the same time I am going to build an application which relates to the problems of this report.To solve the problem I am going to do a survey which will include the CRM and also try to find out if the customers of Quicknet share the same thoughts about having a Social Customer Relation Management. Also if this survey shows what the customers think about the CRM, it could improve the relation between Quicknet and themselves. The result from the survey showed two things.
Fysisk aktivitet för elever med koncentrationssvårigheter
Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.
Utveckling av Publits widgetshop : Hur Publits widgetshop kan utvecklas med hjälp av Valobox APIer.
I denna rapport så redogör vi för vårt arbete med att ta fram en prototyp till bokföretaget Publit.

Vi redogör för de olika faserna som vi har gått igenom och de beslut vi tagit angående grafisk design, interaktion och kodning. Resultatet av projektet blev en fungerande prototyp som visar hur Publit med hjälp av Valobox kan skapa en ny funktion till sin widgetshop som gör så att användarna kan provläsa böcker innan de köper dem. .
Utveckling och validering av en LC-MS/MS metod för kvantifiering av clopidogrel och dess metabolit i plasma
Clopidogrel is an antiplatelet substance that prevents blood coagulation in the arteries. It is an inactive pro drug that becomes activated after first-pass metabolism by the liver. The active metabolite of clopidogrel is 2-oxoclopidogrel, which is unstable therefore pharmacokinetic data is obtained by measuring the inactive metabolite clopidogrel acid in plasma. Clopidogrel is taken orally in tablet form. The aim of this project was to develop a LC-MS/MS method for quantification of clopidogrel and its metabolite in plasma. The method has been developed by optimizing the sample preparation.
Exkursion ? ett lärandetillfälle? : Lärare och elevers uppfattningar om exkursioners betydelse för lärande i ekologi
The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning. Open questionnaires and half structured interviews were used to investigate this. Persons who answered the questionnaires and participated in the interviews were senior high school teachers in biology or science and high school science students. All the teachers and most of the students thought that field trips in ecology resulted in increased learning.
Energiåtervinning : av kompressorkylvattnet
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Lönsamma erbjudanden : Hur tjänsteerbjudanden och dess kunder formas av Optional Framing
ABSTRACT Title: Lucrative dealsHow service offers and its clients is forms by Optional Framing Level: Bachelor, Business AdministrationAuthor: Gabriel Krogius, Mikaela SörensenSupervisor: Jonas Kågström, department of economicsDate: 2013, AugustIntroduction: That the human mind may be directed by how an offer is designed is not news. However, what is new in the following thesis is whether a person is affected in the case of a service rather than, as previously research, a physical product. Does a person find it harder to separate with something rather than to add an option?Aim: The aim for this thesis is to examine how Optional Framing has affection on service offerings/companies, and in this case on real estate brokerage services. Is it, as earlier, when the human can form her own offer, the final price ends up higher when she is about to add options than removing them?Method: The thesis emanates to achieve earlier results where the difference in this case is that our thesis is targeting service offerings.
Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?
This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
Vikten av icke-diskriminering, barnets bästa och att få höras : - En studie i hur asylsökande barns rättigheter tillgodoses i svensk rätt respektive i Rawls rättviseteori
The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.
Barn och stress.
The purpose of this study is to show how the modern society, with demands, expectations and the time constraints of adults, affects children and the everyday life at the preschool. Our intention is also to show the importance of identify stress symptoms of the children. The study is of qualitative empirical kind and is based on a questionnaire to 19 parents of preschool children at the age of three to five years old. Interviews are made with four preschool teachers on one preschool. An observation of children in possible stressful situations is made during three days each at two preschools. The results show that the modern society affects children and can be stressful. It also affects the everyday life at the preschool.
