En nätverks-RTK-jämförelse mellan GPS och GPS/GLONASS

Från den 1 april 2006 har SWEPOS kompletterat den befintliga nätverks-RTK-tjänsten, som dittills levererat RTK-data för GPS, med ett alternativ där RTK-data för GPS/GLONASS levereras. En del användare har rapporterat att de upplever att GPS/GLONASS inte tillför något och även att det ibland kan ta längre tid att få fixlösning. Andra användare hävdar att de nu kan använda nätverks-RTK på platser där de tidigare inte kunde mäta och är mycket positiva till GPS/GLONASS.Syftet med detta examensarbete var att undersöka hur tillgängligheten för satellitmätning, positionsnoggrannheten och initialiseringstiden påverkades i öppna respektive störda miljöer med GPS/GLONASS jämfört med enbart GPS vid användandet av nätverks-RTK-tjänsten. Undersökningen har utförts med tre olika fabrikat av GNSS-mottagare (Leica, Topcon och Trimble), vilket även medger att en jämförelse mellan dessa till viss utsträckning kan göras.I studien gjordes totalt 1 440 mätningar på sex punkter med kända positioner och med olika grad av sikthinder. Fixlösning uppnåddes inte inom 180 sekunder för 206 (77 för GPS/GLONASS och 129 för GPS) av de 1 440 mätningarna.De extra GLONASS-satelliterna tillför en klar fördel när det gäller möjligheten att mäta i störda miljöer.

tills tron skiljer oss åt : hur uppväxten inom Jehovas vittnen påverkar de sociala relationerna

The purpose of this study was to explore how interpersonal relationship can be affected by groing up in a New Religoius Movement such as Jehovah?s Withnesses and how it has affected them both in their youth and today. The aim was also to explore if there were people in the respondents' environment that was significant to them during their childhood and which support our respondents have received if they were in need of it.We have not found any previous research on children's social relationships within the Jehovah's Witnesses. We therefore believe that this study is of high relevance to both society and also for all the professionals who come into contact with these children. To discover a child in need, knowledge about how their social environment looks like is crucial.

Metodik för detektering av vägåtgärder via tillståndsdata

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

Body Coupled Communication: Ändring av prototypkort

Kommunikation genom att använda människokroppen som  överföringsmedium, med kapacitiv koppling mellan hud och sensor, har varit ett pågående forskningsområde för PAN (Personal Area Network) sedan Thomas Guthrie Zimmerman introducerade tekniken 1995. Anledningen till detta är att undersöka fördelar och användningsområden för en kommunikationsmetod som ej sänder ut RF-signaler och därmed minska risken för obehörig avlyssning.Denna rapport beskriver ett examensarbete som undersöker möjligheten till eliminering av USB- till UART-konverterare på Microchip BodyCom genom mjukvaru-USB-stack och kombinera denna med Body Coupled Communication funktionalitet i en gemensam mikrokontroller. Vidare studeras om programkoden i Body Coupled Communication sändare kan modifieras för att utöka funktionaliteten.Det var givet i förutsättningarna att mikrokontroller från Microchip skulle användas, vidare var lågt pris respektive låg strömförbrukning viktigt, särskilt för sändaren. Metoden för att uppnå detta har varit användning av Microchip BodyCom development kit tillsammans med Microchip USB low pin count development kit och Microchip USB firmwareframework.Resultatet blev att USB- till UART-omvandlare kunde integreras med Microchip BodyCom genom att använda mjukvaru-USB-stack och en modifierad programkod för BodyCom i en gemensam mikrokontroller.Endast fantasin sätter gränsen för vad Body Coupled Communication kan användas till. Det skulle t.ex.

Jämställdhet åt skogen?! En studie som utreder anledningarna till att kvinnorna slutar som skogsinspektorer

Rekrytering och sociala medier - Om konsten att hitta rätt person till rätt jobb på rätt ställe : En fallstudie av Länsförsäkringar Bergslagens rekryteringsprocess

Den vanligaste rekryteringsvägen är genom informella kontakter och spontanbesök är den näst vanligaste vägen. Arbetsförmedlingen (AF) som rekryteringsväg minskar ständigt och sociala medier används allt mer som rekryteringsverktyg. Många företag har svårt att rekrytera personal med rätt kompetens. Syftet med uppsatsen är att undersöka hur och vilka sociala medier som används i rekryteringssammanhang. Forskningsstrategin är en fallstudie av Länsförsäkringar Bergslagens rekryteringsprocess.

Kisa Stationsamhälle : från kyrkoby till municipalsamhälle 1895-1905

The current field of research concerning the impact of railroads in Sweden beside from the State main-line network is relatively narrow. Including cultural impact to the area narrows the results even further. The purpose of this study is to open the field even more into the local societies and to what extent the impact of the introduction of railroad might have had on smaller county villages. Sweden holds a unique position concerning ?station towns? or ?railways towns? in terms of railway policy and the industrial development in towns that were affected by the railway, as the affected towns continued development were based on a hybrid between direct democracy and adaptations of city-law policies.This study takes place in Kisa, a small town in southern Östergötland that during the beginning of the 20th century turned into a municipal community due to the building of Östra centralbanan (roughly translated Eastern central-line).

Kvinnliga virkesköpare inom Holmen Skog

Holmen Skog has only five out of 70 wood buyers who are women, This report is seen as a step in the process towards gender balance in the company. This is a problem that is equal over the entire forest industry in Sweden. They all think that sexual equal workplaces are very important to remain competitive, see things from different perspectives and development of the company. The survey was done by sending out questionnaires to all women who work and have worked as a wood buyer at Holmen, and as many men of both categories. These four categories became a total of twenty persons. To map the industry another questionnaire was sent out to the six largest forest companies in Sweden. The survey found that female wood buyers not finished their work earlier than men did, as they thought before.

Planering av väginvesteringar :

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.

Kraftvärmeverk i glesbygd - en möjlighet?

Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.
