Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering
Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
Löst folk : Om konstruktionen av lösdrivarproblemet under 1920-talet
In the 1920s the law against vagrancy had been unaltered since it?s introduction in 1885. During that period, Sweden had undergone great social and political transformation in the wake of industrialisation, urbanisation and democratisation. The political landscape had changed and the social sciences were organising knowledge in new ways. The public opinion realised the need for a review of the vagrant law that better corresponded to the modern times.
Medeltid i samtid : Salvestaden en rekonstruktion i mellanlandet
The Middle Ages in contemporary time ? Salve City; a reconstruction in the Between Land is an essay dealing with the reconstruction of medieval Kalmar. The Salve City is a melting pot of such diverse fields as archaeology, pedagogies, reconstruction, historical tourism, regional development policy et cetera. Together, these parts form a space for research and mediation, business and pleasure, a place where commercialism and historical tourism can function alongside with history enthusiasts and entrepreneurs. Both pros and cons of the use of a reconstructed part of medieval Kalmar are debated..
Animerad TV-vinjett : utsmyckning eller genre? En studie i animerad TV-vinjett
Today, the TV vignette is considered an embellishment to a TV program, despite its broad audiences and unique appearance. We wanted to find out if the television vignette has some common features and conventions but also find out how it relates to genre.We used a case study where we analyzed ten vignettes that we chose from certain criteria. We used a model based on image analysis that we modified to fit our needs. The main parts of each model consisted semiotics, imagery, dramaturgy and sound.We also made a couple of interviews with people who are active or used to work with vignettes. As a result we discovered that the television vignettes consist of certain conventions and that the vignette will not be considered as an independent genre, until the public has accepted it.
Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.
Maskinskydd på rullriktverk
ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.
Nulägesanalys med utgångspunkt från införande och utveckling av en intranättillämpning
This report is about an investigation which has been done as an assignment in aninternational company. An Intranet has been implemented in parts of this company, andprimarily there is a local group of people in the company which is responsible for thelocal Intranet as an informationsystem. This local group of people is also responsiblefor further development of the use of Intranet as an informationssystem in the localorganisation. To create a starting-point for this development, I have done aninvestigation that deals with:· acceptance of Intranet as informationssystem among members of the industrialmanagement.- what factors affect acceptance of Intranet in a negative way- what factors affect acceptance of Intranet in a positive way· rules by which further development of Intranet is supposed to be based on· existing and needed Intranet-applications..
Bellevue - en studie av verksamheter och småindustri i stadslandskapet :
How can we plan so that smallscale industry and businesses can become an integrated part of the city?
The densifying process in search of new housing areas that is going on in most swedish cities threatens to undermine the diversity and complex make up of central parts of many cities. To sustain industrial activities in central locations is critical to this diversity.
This thesis discusses how to reach a sustainable city planning with Bellevue, a small industry and business area in central Gothenburg, as an example..
The Origin : en jämförande tolkningsstudie mellan två skapelseberättelser, med fokus på kvinnan
The purpose of this paper is to interpret two stories of creation and compare them to each other with focus on the gender perspective. The interpretation is generally limited to the creation of mankind and how women are represented in each particular story. The stories I?m interpreting is the story of creation from the Holy Bible, the so called genesis, and from The Nag Hammadi Library?s story of creation called On the origin of the world. I want to show the difference between these two stories when it comes to the women?s position and in what level she is described.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

Förberedelse för förändring : Förutsättningar och behov vid implementering av affärssystem
Organizational change is hard to achieve, but if an organization doesn't change it might risk its own existence. Effective resource allocation and increased control of the internal production are examples of how organizations try to increase its competitive advantage. An ERP system (Enterprise Resource Planning) can help an organization to achieve this by providing management with direct access to a wealth of real-time operating information, streamlined dataflow, and making the company's business processes more effective. Like other IT-related projects, ERP investments are associated with large risks. Many projects failure during the implementation in one way or another.
Materiell processledning : Genom ett förstoringsglas
Den materiella processledningen utgör ett officialintrång i parternas dispositionsrätt och är ett inkvisitoriskt element i en processform som annars präglas av kontradiktionsprincipen. Mot bakgrund av att institutet är främmande för den kontradiktoriska processformen uppkommer naturligt frågan om varför institutet skall existera.Den materiella processledningen syftar till att avhjälpa parts fel och brister vid utformandet av sin talan. Processledningen delas traditionellt in i en formell och en materiell del. Denna indelning ter sig främmande, då såväl den formella som den materiella processledningen syftar till att handläggningen av rättegången ska fungera på bästa möjliga vis, varför den egentliga gränsen mellan instituten då suddas ut.Dispositionsprincipen skall utgöra den dominerande delen av en rättegång. Processledningen skall verka som ett komplement därtill för att rätten, i första hand, skall kunna effektivt föra fram en talan till avgörande och prövning av det som parten vill ha prövat.
