Betesdrift vid automatisk mjölkning i ekologisk produktion :
An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.
Tal till text för relevant metadatataggning av ljudarkiv hos Sveriges Radio
Tal till text för relevant metadatataggning av ljudarkiv hos Sveriges RadioSammanfattningUnder åren 2009-2013 har Sveriges Radio digitaliserat sitt programarkiv. Sveriges Radios ambition är att mer material från de 175 000 timmar radio som sänds varje år ska arkiveras. Det är en relativt tidsödande process att göra allt material sökbart och det är långt ifrån säkert att kvaliteten på dessa data är lika hög hos alla objekt. Frågeställningen som har behandlats för detta examensarbete är: Vilka tekniska lösningar finns för att utveckla ett system åt Sveriges Radio för automatisk igenkänning av svenskt tal till text utifrån deras ljudarkiv? System inom tal till text har analyserats och undersökts för att ge Sveriges Radio en aktuell sammanställning inom området. Intervjuer med andra liknande organisationer som arbetar inom området har utförts för att se hur långt de har kommit i sin utveckling av det berörda ämnet. En litteraturstudie har genomförts på de senare forskningsrapporterna inom taligenkänning för att jämföra vilket system som skulle passa Sveriges Radio behov och krav bäst att gå vidare med. Det Sveriges Radio bör koncentrera sig på först för att kunna bygga en ASR, Automatic Speech Recognition, är att transkribera sitt ljudmaterial. Där finns det tre alternativ, antingen transkribera själva genom att välja ut ett antal program med olika inriktning för att få en så stor bredd som möjligt på innehållet, gärna med olika talare för att sedan även kunna utveckla vidare för igenkänning av talare.
"Harry Potter är inte lämplig i skolan" : En jämförande studie mellan serbiska och svenska lärares syn på litteraturundervisning.
This thesis is about Swedish and Serbian teachers and their views on how literature should be taught to students in high school. The twist is that these teachers live in two different European countries, and work under two different educational systems. Three of them work in Stockholm, Sweden and the other three in Belgrade, Serbia. The purpose of this thesis was to find similarities and differences in the practice of teaching literature among teachers in these two different educational systems. The teachers were interviewed separately and spoke freely about their views and methods when teaching literature.
Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.
The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.
LOST IN TRANSLATION: Kommunikation förlorad i informationssystem
This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.
Ändring av befintligt ridhus : Gävle Fältrittklubb
In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.
Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna
The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.
Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.
Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting
This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..
Risker i flera dimensioner : Om kopplingen mellan designmönstret MVC och projektrisker
The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
Om utformning av ett verksamhetssystem : En utvärdering av nuläge, tillgänglighet och erfarenheter
These days most companies conduct some form of work for the external environment, quality and safety. In connection with this work, some companies have chosen to get management systems certified by any applicable standard for one or more of the fields while other companies have chosen other ways that are not associated with certification.In light of the fact that the individual systems are becoming unmanageable an increasing number of these companies are faced with the decision whether to integrate and coordinate these different systems or not. In order to study the possibilities of a company?s system coordination an assessment of elements particularly interesting for the company was performed. The key elements and focuses in the evaluation were staff access to information, experiences from other companies and environmental work status for some of the organization's companies.
System 348 - Rekombinator : Analys av reglerproblematik vid O2
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
