Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Sedan ett antal år tillbaka väljer allt fler att bo i innerstaden med små barn. Det har skapat ett enormt behov av nya förskoleplatser. Den vanligaste lösningen har blivit paviljonger med tillfälligt bygglov där antalet moduler monteras efter behov.  Med denna flexibla möjlighet tycks dock barackerna ha kommit för att stanna och blir oftast något helt annat än den provisoriska lösning de en gång var ämnade för. Ett annat problem som förskolan står inför är att maten inte tillagas på plats utan körs ut från storkök och levereras i värmeslådor. Det fungerar förvisso men den pedagogiska poängen går om intet. Syftet med projektet har varit att rita ett dagis i Stockholms innerstad som med samutnyttjade funktioner ger ett flexibelt förslag. Till förskolan hör ett restaurangkök som också serverar en restaurang, öppen för allmänheten.

Communicative recycling, to repeat utterances uttered by oneself or others, is a common phenomenon in all societies and languages. The talk of persons with autism often features recycling. The aim of this study was to identify different forms of recycling in communication involving a boy with autism and to describe its functions. Communication between the boy with autism, who used Picture Exchange Communication System (PECS) to communicate, and his parents and teachers was videotaped. The conversations took place in familiar settings, in the boy?s home and at his pre-school.

The purpose of this paper consists of examining the different ways of thinking about death and life beyond death conveyed in the game Grim Fandango Remastered. This was done by using a theoretical framework consisting of a self invented definition of death called "Bodily death". This definition consists of common notions about death such as cessation of life functions like movement, metabolism, respiration and overall cessation of brain functions. It also included cessation of vital processes, which includes the ability to make energy transfer, making reparations, for example by cell replication, as well as the waste system of the body.  Besides this, the study examines the prevalence of dualism, a conception that views the soul essential to the individual's mental state. Two kinds of dualism were investigated, simple dualism with the assumption that the individual is made up of the soul, and compound dualism, where soul and body are dependent on each other for the survival of the individual.

AbstractSeveral of researchers have reflected that the school ought to be developed to a learning organization. A method as proceed from such a perspective and should be able to match a local child- and educations administration is problembased school development. To investigate in which ways a child- and educations administration prosecute a problem based learning inside the organization a case study was used as research strategy. The question this report gives answer to is:In what/which way works a child- and educations administration in a rural district with a method to fulfil a problembased learning.To collect empiric data a canvassing inquiry was accomplished among the child- and educations administrations group of management. According to the research result it can declares that there are good conditions for the organization to prosecute problem based school development, but there is yet a great deal to do before it´s can be said totally fulfilled.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Background: The project controller is a function witch evolved due to the strong gaining ground of project operation. Why the area of the project controller is interesting to study is explained by the fact that increasing knowledge of this function is important in order to make project operation work well. The fact that opinions in this field disagree, further increases the interest of the field. In order to study the function of the project controller three companies have been singled out. They are IFS, Intentia and Saab Bofors Dynamics.

Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

Produktionen och distributionen av fjärrvärme i Luleå kommun sköts av två företag, LuleKraft AB och Luleå Energi AB. Under 2011 utökades samarbetet företagen emellan, med bland annat gemensam driftspersonal. Detta ger förutsättning för ett mer anpassat och optimerat produktionssätt. Med detta som bakgrund skapades en modell över fjärrvärmenätet och tillhörande anläggningar, för att kunna skapa riktilinjer för effektiv produktion vid olika driftförhållanden. Viktiga komponenter för systemet är? Lulekraft - ett kraftvärmeverk vilket eldar processgaser från SSAB och olja för att producera fjärrvärme och el? Fjärrvärmenätet - 42 mil långa ledningar förser i princip hela Luleå kommun med fjärrvärme? Hetvattencentraler - när LuleKraft inte räcker till för att täcka fjärrvärmebehovet finns möjligheten att använda dessa där bränslet är processgaser, olja, pellets eller elFjärrvärmenätet och hetvattencentralerna ägs av Luleå Energi AB men hela systemets drift sköts av personal på LuleKraft.

This examination work is about implementation of Cisco Systems Network Admission Control (NAC) within a leading IT-company in region of Jönköping. NAC is a technique that is used for securing the internal network from the inside. NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

This study aims to describe the conditions, of which some youths who live in a segregated area in Sweden, see as important for their development of an identity. The study have been conducted in a manner where we put the youths own words in focus. The youths are in charge of deciding what they regard as important for their own development of their own identity. In this study we assume certain contexts, of which we base the study. These contexts include the society, the urban districts, the school, the family, and the language.

Utveckling av ett köpcentrum är ett komplext system som involverar många aktörer såsom kommunen, fastighetsägaren, investerare, långivare, konsulter, analytiker, arkitekter, detaljister och givetvis även slutkonsumenten så att visionen om att vara den ledande bland köpcentrum hierarkin realiseras.Det tillkommer nya handelsytor i relation till befolkningsunderlaget i Stockholms län där konkurrensen, kundernas krav och e-handeln ständigt ökar. Detta kommer i sin tur sätta press på ledningen för att fastställa nya tydliga strategier för framtida visioner. Vid utvecklingen av ett köpcentrum har extern rådgivning tagits och därmed ett investeringsförslag har föreslagits. Vilka faktorer som har tagits med i beslutsunderlaget är det väsentligaste.Utgångpunkten med denna studie var att belysa hur ett köpcentrum behåller sin kommersiella kvalitet och därmed möta den framtida konkurrensen bättre. En Jämförelseanalys av två valda objekt i Stockholms län har fullgjorts för att belysa närmare framgångsrika nyckelfaktorer såsom läge, tillgänglighet och koncept.
