Applikation för sökning i databaslogg samt design av databas
Den här rapporten behandlar ett system som använder en databas som lagringsplats för loggar. En bra metod för att hämta ut dessa loggar saknades och databasdesignen behövde förbättras för sökningar i loggarna. En applikation för att hämta och söka i loggposter från databasen skapades. En undersökning om hur databasdesignen kunde förbättras genomfördes också. Båda delarna gjordes i ett projekt för att de hörde ihop.

Modellering av hydrauliskt aktuatorsystem
This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
One size does not fit all - En studie om hur tillämpningen av SDT-principen har förändrats inom GATT och WTO
Denna uppsats analyserar utvecklingen av principen Special and Differential Treatment (SDT) i den internationella handelsregimen. Fokus är på förändringen i tillämpningen av denna princip. Uppsatsen identifierar hur principen har tillämpats sen dess uppkomst samt hur ett skifte i det ekonomiska utvecklingstänkandet kom att utgöra en avgörande faktor för den nedgång i tillämpning som observerats. Vidare identifierar uppsatsen också hur nya dimensioner av världshandeln har skapat nya problem för utvecklingsländerna, vilket i sin tur har skapat ett behov av en fortsatt, men i många avseenden annorlunda, tillämpning av SDT-principen.Uppsatsen kommer till slutsatsen att det nya ekonomiska utvecklingstänkandet har suddat ut rationaliteten bakom det forna tillämpandet av SDT-principen. Samma utvecklingstänkande har dock lagt grunden för en ny tillämning.

Att det finns ett generellt mönster i våra fallföretags stage-gate-systems produktutvecklingsprocess.? Att det kan finnas ett samband mellan bransch, utvärderingsenhet och utvecklingsprocess..
Solenergi En del i ett långsiktigt, hållbart byggande
The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Logicat
I vår produktion har vi tagit fram ett system för order- och lagerhantering,
med vikt på realtidsuppdateringar, åt en extern mottagare där infrastrukturen
inte hängt med i företagets utveckling.
Vi valde detta projekt i syfte att bredda våra kunskaper inom både
programmering och projekthantering.
Denna slutreflektion tar upp den förundersökning vi gjorde för att kunna
besluta om vilka verktyg vi använde i utvecklingen, den tar även upp vårt sätt
att hantera och planera projektet. Under projektet har vi arbetat med en
egenutformad arbetsprocess vilken även beskrivs här.

Our production has been to design a system for ordering and supply management
with emphasis on realtime updates to an external recipient, where the
infrastructure has not kept pace with the development of the company.
We chose this project in order to broaden our knowledge in both programming and
project management.
This text brings up the investigation we made to decide which tools to use in
the development, it also brings up the way we managed and planned our project.
During the project we have worked with a self-designed software development
process which is also described here..
Förpackningsdesign i en varumärkesstärkande process : En fallstudie av varumärket Coca-Cola
Nowadays, packaging design is seen as a competitive tool and its importance for corporations is becoming increasingly apparent. The rivalry within homogeneous markets puts high demands on differentiation and the ability to create something more than the product itself. With this fundamental question, the soft drink industry has been examined and a case study of the brand Coca-Cola has been performed. The aim is to investigate how packaging design is used as a tool for strengthening a brand and to explore which additional values this contributes. In addition, the study observes the most important factors in the development of packaging design.A theoretical work of reference, consisting primarily of theories related to branding, design development and visual identity, has been developed to support the study.
En jämförelse mellan traditionell och modern taktäckning av industribyggnader
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.
Konstruktion Signalgenerator
SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.
