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.
Kan professionell skepticism användas för att förutse revisorers beteende?
Auditors have a big role in society. The question of auditor independence has been debated frequently after the financial crisis. Long auditor tenure with clients has both advantages and disadvantages so the question is hard to solve.One of the traits that are encouraged with auditors is professional skepticism. An important part of professional skepticism is the personal skepticism of the auditor. The purpose of this dissertation is to investigate if a high professional skepticism can increase auditor independence by increasing profession identification and decreasing client identification.
Förbättringsarbete på monteringsbana
In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

Automatisk Identifiering av Inandningspauser i Spontant Tal - ett HMM/ANN-hybridsystem i Matlab
This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.
Hemma i världen(globen?) En studie av social förändring och identitet
In this thesis my purpose is to study the mechanisms and discourses that are the foundations for identification processes, in a contemporary society characterised by increased mobility. By means of a fictitious life history, I relate to this problem constantly through the work. At the beginning of the essay I discuss the traditional, western, philosophical view of the self and its surroundings, which eventually leads me to focus on the theories of the sociology of knowledge. From this perspective I choose to examine globalisation processes and mobility, to create an understanding of how these two, changes the circumstances for the individual identification. In my concluding argument I stress that all research or all studies concerning identification processes must take into account that these identifications always take place with regard to time/place which also means, that it takes place both in real space and in imaginary space.
Individual identification in pigs using microchips
Individual identification of pigs could be used in commercial herds for production monitoring, disease monitoring and breeding evaluation. This study investigates the possibility of using microchips designed for dogs and cats to identify individual pigs from birth, through rearing to carcass at the slaughter plant. Two different sizes of microchips, and two different ages of the pigs at injection were tested. Castrates and gilts from ten litters were evenly distributed between chip sizes and injection ages. All pigs were identity marked with both electronic ear tags and injected with microchips.
Metod för analys av elförbrukning i hushåll
Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.
Optimering av ett småskaligtvattenkraftsystem
This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.
Riksantikvarieämbetet - Identifieringen av balanserat styrkort i en offentlig verksamhet: Hur kan processen vid skapandet av Riksantikvarieämbetets balanserade styrkort påverka dess vidare användning som styrmodell?
The Swedish National Heritage Board (RAÄ) is the agency of the Swedish government responsible for heritage and historic environment issues. During the last couple of years the agency has implemented a new management control system, the balanced scorecard, originally developed for profit driven organizations. Organizations within the public sector have other objectives than profit seeking organizations, and there have been difficulties in applying the balanced scorecard model in the public sector. Therefore we find it interesting to examine the reasons behind these difficulties and believe that some answers can be found in the identification process of the balanced scorecard. Therefore we aim to perform a case study of RAÄ and explain how the identification process of the components of their balanced scorecard can affect further usage of the model as a management control tool.
En studie av zero knowledge-identifikationsprotokoll för smarta kort
Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.
Hur du får dina kunder att älska dig mer: En kvantitativ studie som visar hur event som marknadsföringsmetod och med ett varumärke som avsändare kan öka eventbesökarens upplevda varumärkeskärlek
Event marketing has during the last decade become a wide spread marketing method. This is because the marketing clutter has increased heavily during the past years and brands are looking for new ways to reach their target audience. The previously well accepted marketing measurement "satisfaction" has shown tendencies no longer to be sufficient for success in today's competitive marketplace. Therefore, the research has somewhat moved to the measurement "brand love" to explain differences in strategic consumer behavior. That is the background to why this report examines and answers the question if a brand through event marketing can enhance brand love.
Läraren och tjänstemannauppdraget : En studie om lärarstudenters syn på sina framtida tjänstemannauppdrag
The aim of this essay is to examine how future upper secondary school teachers within social science comprehends their future proffessional role. The aim is also to see whether the education is of importance to their suspension for their future professional role. Focus will especially be on the teachers civil servant role, where the aim is to see how their identification suspends to the governmental expectations on their future civil servant misson. The essay is based on a qualitative method, which is focused conversational interviews.The result indicates that future upper secondary school teachers within social science, who are about to finish their education, have a somewhat deeper sense of identification with the teachers civil servant mission compared to those in the beginning of their education. The result also indicates that the future upper secondary school teachers identification are in line with the governmental expectations on their civil servant mission.
Känner jag igen mig? : Etnisk identifikation i barnböcker sett ur ett retoriskt perspektiv
The purpose of this essay is to examine at how to portray characters in the stories and narratives which depicts one of these children's books and if they really have something to ethnicity and its identification to be done.The Research questions is: What are the different identification markers given, to the reading child in the books, which might indicate that the story depicts people of different ethnicities? How are the characters portrayed in the story and which role is assigned to the main character? What story is portrayed and is it relevant to an identifier can occur?The conclusions of the five children's books shows that it is important with identifications markers, to show that there are different ethnicities. For example the analysis revealed the specific features of the illustrations and how the books portrayes someone with a different ethnicity and cultural background as something exotic.In the texts, the analysis showed how it occurred ethnic differences, by explicitly demonstrating differences between the characters. It was found that the characters were produced mostly as good, happy, curious, suspicious and unsympathetic. Common to all the main characters was that they had been placed, in one for them unusual context and that they were trying to assimilate to the new situations.Depictions consisted of realism and fiction.
Identifiering av immateriella tillgångar : En studie om redovisning av tillgångar vid företagsförvärv på svenska MTF:er
An accounting issue that has received attention is the issue of identification of intangible assets in acquisitions. This is because the company's result can be different depending on how much the company chooses to identify intangible assets separated from goodwill. As the practice for identification of intangible assets lacks clarity, companies are able to account for this in different ways. In this study, the manner in which identification of intangible assets are managed by companies listed on Swedish multilateral trading facilities and the manner in which companies distribute the purchase sum on net tangible assets, intangible assets and goodwill in comparison with listed companies is examined. The study emanates from a systems approach and is descriptive.
