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.
Funktionshinder barriär eller genväg till biblioteket? En fallstudie om rörelsehindrades och synskadades biblioteksanvändning
The aim of this Masters thesis is to, from a users perspective, investigate which factors affect the library use for six persons with disabilities or visual handicaps. My method has been a case study and the methods applied are interviews and observation. As a theoretical framework I use Tom Wilsons theories and models about information behaviour and transform them to a model about library use. Answers are sought to the following questions: - What does the library use look like for six persons with disabilities or visually handicaps? - How do they experience the library in their own municipality? - Which factors affect the disabled persons library use and experience of the library? All interviewees showed a very positive attitude towards the library and the majority of them visited the library regularly or received audio books by mail.
Analys och design för strömmande media i DySCAS
This master thesis is a part of the DySCAS project at ENEA. The purpose of this thesisproject is to add support for streaming media and USB support to the DySCAS demonstratorplatform.To achieve this, some of the widely used middlewares available today were studied. The onethat proved to be of most interest is CORBA. Although CORBA?s solution to streamingmedia couldn?t be used due to their use of object programming, the CORBA solution didprovide some interesting thoughts regarding how the USB devices should be handled, in thiscase their ?resource inspector? and ?trading service?.Ethernet was the chosen network to support streaming media.
Vattenfallsmodellen i en webbmiljö
Vid utveckling av nya system finns det flera olika modeller/metoder att använda sig av, till exempel prototyping eller vattenfallsmodellen. Denna uppsats beskriver hur utvecklingen avett webbaserat system för registrering av datorer kan ske med hjälp av vattenfallsmetoden. Fokus på detta arbete ligger förutom själva utvecklandet av registret också på dokumenteringen av de olika stegen som följts enligt vattenfallsmodellen. Detta arbeteförsöker också svara på om denna modell är lämplig att använda vid utvecklingen av liknande system. Uppsatsen tar också upp fördelar och nackdelar om kan uppkomma vid användandet av denna modell..
Om att bygga landsbygd - ett ruralt planeringsexperiment i Botkyrka :
I have studied the suburban
municipality of Botkyrka, south of
Stockholm, from a rural perspective.
Through that I`ve compared how
countryside comes into being with the
planning and building of suburbs.
I have looked for a definition of
Countryside, and found that it is
often explained or defined in negative
terms, as what it is not. In that it
says nothing about what it really is,
or about the qualitiies it has to it.
Botkyrka is a suburb, but it does in
large parts consist of countryside.
Apart from defining countryside and
rural I´ve been searching for a
definition of suburbia, of it´s
structure and the mental picture we
have of it as a cultural phenomena.
In order to understand the role that
suburbs have in planning I describe
their history from Italian
renaissance villas to sprawl.
By opposing urban and rural, modern
urban planning and how rural areas
are created, I´ve come to a
definition of rural planning and the
making of countryside. To make
countryside, planning and building
should come from individual needs and
desires. A relationship to the
surroundings based on continous
interaction between the human beeing
and it´s environment, a constant
process of shaping and reshaping.
To put my thoughts to the ground I
have collected examples of projects
and ideas, that fits into my view of
what rural planning and making
countryside is all about. They are
put in different categories according
to the possibilities of influence and
to what degree it is put into private
hands.
The first category is
?allemansrätten?, every mans right.
That is the rigt to use private land
as long as you don´t disturb or
destroy.
The Potential of B2B Lovemarks: A Managerial Perspective on Strong B2B Brands
Kevin Roberts has extended the comprehension of strong consumer brands to a higher level where loyalty beyond reason is established. He calls this new status Lovemarks. As the concept of Lovemark has only been applied in B2C markets, this thesis is directed to find out the applicability of Lovemarks in B2B context. In order to fulfill the research purpose, three main questions are answered based on a cross-sectional research approach: What role do intangible factors play in B2B branding? Is the idea of B2C Lovemarks transferable to B2B context? How should a B2B Lovemark be characterized? The results of the qualitative interviews indicate insights of high investment and involvement, integrated brand communication, balance between function versus emotion, brand?s trustworthy personality, customer partnership, and finally, the potential establishment of B2B Lovemarks.
Energieffektivisering i befintlig byggnad: En fallstudie av Hägern 11 och EU Green Building
En av samhällets viktigaste frågor idag rör den framtida energitillförseln till den byggda miljön och dess koppling till miljö- och klimatfrågor. Energitillförseln sker idag till 80% genom fossila bränslen och bygg- och fastighetssektorn står idag för 40% av världens energianvändning. De CO2-emissioner som förbränning av fossila bränslen genererar påverkar jordens växthuseffekt. EU-direktiv rörande en effektivisering och minskning av energianvändningen har implementerats för att minska belastning ur energi- och miljösynpunkt på jorden. Sverige har satt som mål att minska energianvändningen med 20% till år 2020 och 50% till år 2050 i jämförelse med värden från år 1995.
Att arbeta enligt BBIC : En kvalitativ studie om socialsekreterares upplevelser av att arbeta enligt BBIC - Barns Behov i Centrum
Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.

Skiftarbete i byggindustrin och dess värde för aktieägarna
The foremost objective of business organizations is to generate value for shareholders and to opt for strategies which optimize it. Hence it is of key concern for business leaders to appreciate how operations best are run to maximize value creation. This study explores how financial theory can reveal the link between one particular business strategy and the corresponding effect on shareholder wealth. The question in focus is whether construction companies can enhance their value creation by implementing shift-work to increase the weekly production rate. The thesis particularly targets apartment block projects in Sweden and has the construction company Peab AB as primary object of study.
Kunskapshus eller offentligt vardagsrum? En undersökning av Lunds stadsbiblioteks ombyggnad
In this study my aim has been to discover what connections can be made between the way of creating a library building and the general values concerning the library activities and the library users. What kind of ideology could possibly be reflected in a library room? My study includes two different parts. First of all there is a theoretical section based upon literature relevant for the subject. Here I try to focus on the libraryÕs role in society as a public room.
Kravhantering ? Brister och lösningar
SammanfattningKravhanteringsprocessen är en av de viktigaste faserna vid utvecklandet av ett IT-system. Kravhantering är alltså grundläggande för att utveckla ett stabilt system som uppfyller beställarens önskemål. Med en väl utförd kravhantering som grund får man ett system som är fritt från bristfälliga fel, utvecklandet av systemet går även till på ett effektivare sätt. Vid byggandet av ett system eftersträvar man alltid en framgångsrik mjukvara. Kravhantering ses som den viktigaste faktorn vid utvecklandet av ett IT-system.Föreliggande studie genomförs som en litteraturstudie där undersöks vilka brister som är vanligt förekommande under kravhanteringsprocessen.
Tillämpning av Unified Process och Design Patterns vid integrering av system
The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.
Ändring av befintligt ridhus : Gävle Fältrittklubb
In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.
