Utvärdering av trafiksimuleringsmodellen RuTSim
Trafiksimulering är ett användbart verktyg då olika typer av vägar ska studeras. Statens väg och transportforskningsinstitut, VTI, har under de senaste åren utvecklat en ny landsvägssimuleringsmodell, Rural Road Traffic Simulator (RuTSim) (Tapani 2005). För att en simuleringsmodell ska vara användbar måste den ge en god överrensstämmelse mot verkligheten. Syftet med detta examensarbete är därför att utvärdera RuTSim, genom att kalibrera och validera två 2+1-vägar och en vanlig landsväg med mötande trafik. Detta både för en implementerad frifordonsmodell samt befintlig modell med trafikinteraktioner.
Tillförsel av använda fosforfilter påverkar inte tillväxten eller fosforupptaget hos korn
The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.
Rörelsemönstrets betydelse : Att öka attraktiviteten i en galleria med Space syntax
The functional connection between the building and the streetscape affects the city and its attractiveness. Stores located in shopping malls with their entrances facing internal walkways, creates segregation between the mall and the streetscape. This segregation implies that the shopping mall loses some of its attractiveness, which may result in a so-called Greyfield mall. The expression Greyfield mall is used for shopping malls that have lost its visitors. Competition from new modern malls and a lack of investments are examples of factors that influence the development of Greyfiled malls.
Att lyssna till pappors röster : En kvalitativ studie av pappors upplevelser kring att befinna sig i vårdnadstvist
This study highlights the problematic situation fathers encounter when they require help and support in a custodial dispute. Previous research shows the emergence of a new, more involved father. In the light of this earlier research, this study will show a father that is willing to fight for his rights to be a present and engaged parent in the case of a separation from the mother. The aim was to analyze the subjective perceptions of five fathers in custodial dispute. This analysis did not only show how they perceive their role as a father and their masculinity but also the way they feel about the help they got from social services and other institutions.
Barns rädslor och oro i möten med sjukvård : En litteraturöversikt
Barns rädslor och oro i möten med sjukvård Författare: Christian Römberg & Pontus Älvehag Sammanfattning Bakgrund: Enligt barnkonventionen räknas varje människa tills dagen de fyllt 18 år som barn. Omkring 200 000 barn söker varje år vård på akutmottagningar i Sverige och cirka 95 000 barn per år är i behov av vård på sjukhus. I mötet sjukvården upplever de flesta barn rädsla och oro för sjukvårdsmiljön, sjuksköterskans mediciniska språk och beteende vilket kan förstärka smärtupplevelsen vid undersökning och behandling. En uppkommen sjukvårdsrädsla kan försvåra framtida sjukvårdskontakter och skapa otrygghet hos barn. Sjuksköterskans uppgift är att ge barnet en god omvårdnad och möjliggöra delaktighet för barnet och närstående för att dämpa rädsla och oro, något som regleras genom barnkonventionen och hälso- och sjukvårdslagen. Syfte: Att belysa vad som ger upphov till rädslor och oro hos barn i möten med sjukvården som patient. Metod: En litteraturöversikt med kvalitativ ansats.
På bron mitt emellan : En kvalitativ studie av elevers sociala kategorisering utifrån känslorna av inkludering och exkludering i specialpedagogiska lösningar
The purpose of this paper is to find more understanding for pupils in compensatory educational situations and get an idea about how they place themselves in the social hierarchy. In my study I have interviewed four pupils with different experiences from school with the common denominator of being placed in a special class during some hours of the week. The purpose of this placement is to get them to achieve better results in various subjects depending on their grade but this also means a social separation from friends in the ordinary class and this doesn't correspond well with the democratic idea of "one school for all".What I found was that these pupils categorize themselves different from each other and while two of the pupils find themselves very included in the school's social network the remaining two had problems functioning satisfactory in a social matter according to their own liking. The feeling of exclusion though can not be connected to their participation in the special class but rather to their earlier social experiences..
När livsformer möts i mikroföretag
Syftet med uppsatsen är att undersöka jobbcoachningsprocessen utifrån ett livsformsperspektiv, genom att utföra livsformsanalys på jobbcoacher och klienter. Relationen jobbcoach/klient står i fokus eftersom det existerar en liten mängd forskning inom området, och jobbcoachningens effekt på arbetslösheten i Sverige har på senare tid ifrågasatts. Livsformsanalysen är även bra verktyg för att undersöka vilka värderingar människor har och varför vi väljer att agera på ett visst sätt. Teorin om livsformsanalys utgår ifrån att människor har olika levnadsmönster och uppfattningar om "det goda livet", vilket benämns som att de lever livsformer. Vi har lagt fokus på kärnbegreppen sociocentrism och neokulturation inom livsformsanalysen: Sociocentrism handlar om människans oförmåga att förstå och erkänna andra livsformer än sin egen.
Budget som styrmedel ? ett effektivt verktyg eller ett onödigt ont?: En fallstudie av den ekonomiska styrningen inom Luftfartsverket
The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.
Från trafiklärare till transportlärare
Abstract (in English)The purpose of this work is to find out what the driving instructor who currently works as a transport teachers feel about today´s driving education to transport high school to how it works at driving school. I describe in the study on how to become a transport teachers and on their everyday work. Even what others have written on this topic on driver training. I also interviewed four driving instructor who currently works as a transport teacher, about what they had for opinions on this issue. The method I have used myself of where unstructured questions to get so descriptive answers to questions as possible.
Portning till ARM Cortex M3 och prestandajämförelse
The Anybus CompactCom modules are today using the Anybus NP30 processor. These modules are used for communication between industrial machines and larger network protocols. The communication loads on these systems are increasing every day and the limiting factor for the system is the processor.HMS, the company that develops the Anybus CompactCom, has shown interest for a benchmark test between the old processor and a new processor, ARM Cortex-M3. This project includes that benchmark. To be able to get results that reflect reality a test environment was created to simulate Anybus CompactCom conditions.
Odefinierade platser i staden : med studie i Söderälje
The purpose of this master thesis is to attract attention to the undefined spaces of our urban landscape and emphasize the need of these spaces in the city. The different values of these spaces are here clearly presented so that they can be considered when real estate developers show a particular interest in any one of these undefined spaces.
The term undefinied spaces can mean a lot of things. The spaces that I now choose to define as undefined spaces are neither planned nor designed. It could for instance be a piece of leftover land in between two residential areas, or as times change, a formerly planned area might be forgotten and left to its own.
Bikeshare - Elcykel : Framtagning av dockningsstation till cykeldelningssystem
The project was carried out together with OC Off Course who manufactureand distribute mainly electric bikes.In today?s society, alternative sources of transportation becomes more andmore present and several bicycle sharing programs arises in major citiesacross the world every year.Something that doesn?t exist too much as of yet is bike sharing programsthat uses electric bikes. An electric bike is a convenient way oftransportation as well as a good way of avoiding traffic. With an electricbike you avoid having to sweat when biking over hills or when you need totravel over longer distances.The goal of this project is to develop a bike sharing station according tothe functions need to be met.This thesis Is based on Fredy Olsson´s methods principkonstruktion aswell as a couple of concept generating methods from Kenneth Österlin.From this, a number of sketches were made that later was evaluated inseveral steps in conjunction to a set of specifications. A 3D model of theselected concept was later made in CatiaV5 for a complete product..
Separation av två klasser av åtta-dimensionella reella divisionsalgebror
This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).
Kvinnors kropssuppfattning och sexualitet efter genomgången mastektomi
SAMMANFATTNINGBakgrundBröstcancer är den vanligaste cancerformen bland kvinnor och cirka 7000 kvinnor drabbas av sjukdomen varje år i Sverige. Trippeldiagnostik som består av en klinisk undersökning, mammografi och cellprovtagning är en metod som hjälper att tidigt upptäcka cancern. Vanligaste behandlingsformen är kirurgi som omfattar olika typer, till exempel bröstbevarande kirurgi och mastektomi. Diagnosen bröstcancer kan leda till försämrat välbefinnande respektive försämrad fysiskt, emotionell och social funktion som i sin tur kan leda till en traumatisk kris. Kvinnors kroppsuppfattning förändras efter genomgången mastektomi vilket lämnar en påminnelse om sjukdomen i form av ett permanent ärr.
Link QualityControl (LQC) i GPRS/EGPRS
This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.
