[demos.v1.0] till [demos.v2.0] : En fallstudie av modifierbarhet
This report is an examination paper in computer science at University of Växjö. The report will focus on the possibility to create adaptable systems and to cost calculate the work needed to modify a system to meet new demands. A project [demos] developed by Interactive Institute studio [12-21] in Växjö is the starting point in our work. They have during a period of two years developed a prototype of a system which intends to get youth and democratic selected representatives a communication platform where they may communicate with SMS. Today they are in a position when they want to develop the system for other user groups with slighter different purpose and to do that they need a more flexible system.
Polyakrylsyras förmåga att lösa upp hårt slam från PWR-ånggeneratorer
Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.
Metod för beslutsstöd vid formulering och uppföljning av en kommuns klimatmål : Fallstudie Uppsalakommun
The purpose of this study is to create a method that can be used to produce decision supportdata for the climate goals of a municipality. The method should be able to demonstrate the potential for reducing energy use and greenhouse gas emissions for measures aimed at the stationary energy system in the municipality. It will be used to make long term projections of energy use and greenhouse gas emissions in order to be able to demonstrate the ability to reach climate goals. The aim was also to test the method's applicability by using the municipality of Uppsala and the Uppsala climate protocol project in a case study. Uppsala climate protocol is a project consisting of participants from business, government and organizations that voluntarily want to commit to reducing their carbon footprint by reducing their energy use and thus work to achieve the municipality's overall climate goal.

Also being examined is how the event affects Stockholm city?s tourism industry. To be able to fulfill the purpose of the thesis a qualitative research has been used and two persons with allot of knowledge about Stockholm Pride and Stockholm?s tourism industry has been interviewed.
Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell
The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.
Systemutveckling i praktiken - konsten att tillmötesgå den okända användarens krav
ABSTRACT
System development has become more and more concentrated on development for the
Web and this has resulted in larger target groups. It will most surely continue
to be so considering that the Web will be the infrastructure of business and
services in the future. A big target group involves that the owner of a system
can earn a lot of money from the paying users, but that assumes that the system
can meet user needs. If a system on the Web does not satisfy the user?s demands
then they will use the competitor?s system instead because it is only a
mouse-click away.
Navigering, sensorfusion och styrning för autonom markfarkost
The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

Simulering av en framtida presslinje - en analys av design och prestanda
Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).
Systemen med rätt inställning - En studie om whistleblowingsystem i Sverige
In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".
Effektutveckling i den koncentriska fasen i bänkpress och knäböj
Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
Om hur en banks value at risk bäst skattas med expected shortfall
Bakgrund: Om VaR kan estimeras väl med hjälp av ES-metodik, kan man få bukt med VaR-måttets brist på sudadditivitet (vilken innebär dels praktiska problem vid utformning av finansiella organisationers limitstrukturer, dels teoretiska problem i enlighet med Artzner et al (1997, 1999)) samtidigt som man uppfyller det formella kravet på att rapportera sitt VaR på 99 %:snivån. Syfte: Att undersöka hur väl ES ? estimerat på olika konfidensnivåer och med olika metoder ? duger till att skatta en banks 99 %:s-VaR. Metod: Två ES-metoders och sex VaR-metoders förmåga ? både avseende frekvens (Kupiec-test) och oberoende (eget längsta-följd-test) ? att skatta 99 %:s-VaR utvärderas och jämförs.
ERP-implementation och processkartläggning : En studie om implementering av ett ERP-syste, och vilka fördelar en processkartläggning kan ge för kravställandet.
To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.
IT-konsultens konsultationsprocess
How does IT-consultants reason in their consulting process regarding the
development of a clients IT-based internal recruitment system?
The purpose with this paper is to investigate how an IT-consultant is reasoning
in a consulting process and investigate whether consultants are using
established models and methods in their work.
We have chosen to work with a qualitative examination to attain our purpose. In
our work gathering the empirical facts we have been working with a case study,
an observation and a simulation exercise. The combination of these has made it
possible to carry out the paper and produce the most correct data possible.
Conclusion: We state that IT-consultants do not use any theory-based methods,
they use process methods created by themselves and their company.
Prognosvarians ? Effekten av analytikers prognosvarians på aktiekursen
Syftet med vår studie är att studera förhållandet mellan analytikernas prognosvarians och variansen i aktieavkastning i nära anslutning till rapportsdagen. Vi ämnar också studera effekten av analytikernas uttalanden på företagens aktiekurser. Därmed undersöker vi indirekt hur marknaden som helhet utvecklas med koppling till analytikernas vinstprognoser. Vi använder en kvantitativ studie, där vi genom regressionsanalys undersöker sambandet mellan analytikernas prognosvarians och variansen i aktieavkastning i nära anslutning till rapportsdagen. Vidare användes ?Event study? metoden och finansiell marknadsdata för att möjliggöra undersökningen.
