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.
SAB-systemet och Yahoo! En jämförelse rörande traditionell och ny klassifikation
The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.
SAB och Dewey vid Uppsala universitetsbibliotek : En attitydundersökning bland bibliotekarier på 6 biblioteksenheter
The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.
Småpratets betydelse för ledarskapet
Title: The significance of small talk on leadershipDate of seminar: 13 October 2010Course: Bachelor paper in Business, in Organization, 15 ECTSInstitution: Swedish Business School at Orebro UniversityAuthors: Linda Andersson & Ebba HallbergAdvisor: Gabriella WennblomPurpose: The purpose of this paper is to identify and describe how leadership is affected by the small talk, with these three managers. This with the manager?s perspective as a starting point, within the three services we examined.Research methodology: This paper is based on a qualitative method. Targeted open interviews were carried out with three respondents. Literature in the organizational field has been searched through to give a base for the study.Theoretical framework: This paper uses the theory of communication, the theory of leadership and the theory of small talk.Conclusion: The conclusion we make is that the small talk makes it easier for the modern leadership, this is because the small talk, among other things, allows the manager to spread information and to avoid misinterpretation, and that the manager become more involved in the company.Keywords: Communication, small talk, leadership.
På upptäcktsfärd i öppna förskolan : en institution som väcker frågor
Denna uppsats handlar om öppna förskolan, en verksamhet för barn och föräldrar som vissa kommuner väljer att tillhandahålla. Trots att verksamheten funnits drygt 30 år, är den sparsamt utforskad. Uppsatsarbetet har därför inriktats mot ett explorativt sökande efter olika föreställningar om öppna förskolan. Föreställningarna har på formuleringsarenan eftersökts i tryckta källor, och på realiseringsarenan genom en etnografiskt inspirerad fältstudie i två öppna förskolor. Syftet har varit att uppnå förståelse för arenornas föreställningar om öppna förskolan och hur dessa föreställningar förhåller sig till varandra.
Att skapa en kulturell mötesplats : möjligheter och begränsningar
The purpose of the essay is to discuss from the theory about the established and the Outsiders if the Culture Centre Blå Stället can serve as a meeting point between the majority of the people and the minority of the people in Gothenburg. The idea of Blå Stället is that it shall work as a house available for everyone and as a cultural meeting point between people in and outside Angered. I argue if Blå Stället really is a place where people from Gothenburg as a whole go or if there are some hindrances for their visions. My study is comprised of interviews with three of the staff at Blå Stället. With the theory about the established and the outsiders I want to show that the division in the city between ?them? and ?us? has to do with differences of power.
Prototyputveckling av digitalt styrsystem för torkskåp
Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..
När rummen råder : En studie om skolan som disciplinerande rum
This study titled When the spaces dominate A study of the school as disciplinary rooms is a study where the emphasis is on quality and where the results are based on observations. The purpose of the research was to analyse rooms and other artefacts in the school as seen from Foucault?s analysis of power. He emphasised that power is expressed in human relationships. To understand how that power is used one can study the techniques adopted and resistance offered.
Bilden av kvinnan i Library of Congress Classification En genusstudie av Library of Congress Classifications första och senaste upplaga
I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are.
En kartläggning av webbaserade open-source GIS-lösningar
Intresset för kartbaserad information på Internet ökar i rask takt. Samtidigt växer önskan av att sprida geografiskt material i form av interaktiva webbkartor utan att vara hänvisad till dyra, professionella GIS (Geografiska Informationssystem) programvaror. Idag finns det en rad open- source lösningar på webbaserade GIS som utan kostnad får utnyttjas, spridas och byggas ut efter egna önskemål. I detta examensarbete undersöks ett 20-tal open-source webbGIS-produkter enligt en allmängiltig mall som vi har tagit fram för att kunna jämföra olika lösningar enligt klart specificerade kriterier. Dessa omfattar bl.a.
Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning
Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.
Synen på Säkerhet och Immigration : Finns det ett samband?
The aim of this study is to explore howEuropean changes in the view on securityrelates to the view on immigration and viceversa. The answer to that question is basedupon collected data from three separatetime periods; the 1950s, 1970s and 1990s.These time periods are seen as importanthistoric decades when political changes,assumed to have affected the views onsecurity and immigration, have occurred.According to certain criteria each timeperiod has been labelled in terms ofnarrowed/widened view on security as wellas restrictive/open view on immigration.The hypothesis of the study is that, whencompared, a constant pattern can be seenbetween the historical labels of eachphenomenon, where a narrow view onsecurity goes hand in hand with an openview on immigration and similarly a widesecurity view relates to a restrictive viewon immigration.The conclusion of the study gives supportto the hypothesis. During all three periodsstudied a restrictive view on immigrationrelates to a wider view on security while anopen view on immigration relates to anarrower view on security. Thisrelationship goes both ways..
Kommunikationsproblem och bemötande inom referenssamtalet
This bachelor thesis is about communication problems and treatment during the reference interview. The purpose was to investigate the reasons of why users? information needs are not always understood by the librarian and what to do about it. I have also investigated what kind of skills that can be useful for librarians to have and how a librarian can act in a way that makes the user feel welcome during the reference interview. The method I used was a literature study and an own study through interviews of library users.
Omvårdnad och organisationsstruktur : En odelbar helhet
Komplexitetsteori ger ett nytt synsätt på hälso- och sjukvårdens organisation, vilken beskrivs som ett komplext adaptivt system, vars ingående delar står i en inbördes relation till varandra och interagerar i dynamiska, icke linjära mönster. Detta synsätt kontrasterar mot det mer traditionella som ser sjukvården som en hierarkisk och linjär organisationsstruktur. Denna litteraturstudie har som syfte att beskriva hur omvårdnad kan påverkas av en organisationsstuktur präglad av teorin om komplexa adaptiva system. Elva artiklar granskades och analyserades, varvid fyra teman framträdde: ledarskap och medinflytande, samverkan, intellektuell mångfald och informationsflöde. Resultatet visar att omvårdnadsproblem uppmärksammades och åtgärdades snabbare på enheter som organiserats med fokus på medarbetarnas delaktighet och där ledarskapet främjat en hög grad av samverkan inom och mellan vårdens olika professioner samt verkat för ett klimat där alla medarbetare fritt kunde framföra och delge sina åsikter.
"Lika enkelt att pröva den där kärleksgrejen" : Svenska mäns erfarenheter av relationer som inletts med sexköp i Thailand En kvalitativ studie
The aim of this study in social work was to investigate, describe and analyze six Swedish men?s description and experiences of relationships with bargirls in Thailand, whom the men initially paid for sexual services. We also aim to find out how these men look upon prostitu-tion, masculinity and gender and we analyze these themes in relation to the men?s description of their relationships. The theoretical approach was social constructivist theories of masculini-ty in combination with gender theory.
