Resefria möten : Ett projekt för att minska slöserier på arbetsplatsen

AbstractThis degree project is about having meetings in The Swedish Social Insurance Agency, which is awide organisation. This work will concentrate on one of the projects going on within theorganisation which is travel-free meetings, where they are building a video meeting system thatallows the employees in the organisation to be able to meet with each other through the use ofvideoconferencing instead of physical meetings.In this work we will show how Kaikaku (radical system changes) along with Kaizen (continuouschange) can support an organisation to become more efficient and reduce wastage. We have donethis work in an organisation that is present in over one hundred locations in Sweden.The Social Insurance Agency has over 13 000 employees at over one hundred locations inSweden.The organisation has to be close to their customers and provide the best service aspossible. To be able to work in a uniform way, the employees get together and have meetings.Some meetings are just progress meetings and takes perhaps no more than two hours to complete.However, if seven employees from seven different locations need to have meetings, in the worstcase, they all have to meet in a common place.This is expensive for the organisation in travel costs, time and absence from work, but thetravelling also contributes to environmental pollution if the employees are travelling by a fuelpoweredvehicle.A whole day could go lost for having a meeting in about two hours if all sevenemployees went from their own cities to e.g. Stockholm for the meeting.Muda (wastage) of travel created several different types of Muda, namely:? Wastage with anticipation when the employees had to wait for e.g.

Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller

Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.

Majstorkning :

The corn plant came to Europe with Christopher Columbus in the 14th century and have ever since bin cropped here, but corn haven?t bin very common in Scandinavia until recently. The mainly use for this crop silage but even corn for grain is cropped in Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen Sverige is the biggest buyer of corn at the moment.

Utvärdering av mötesfria vägar : Analys av olyckor på mötesfria vägar i Karlstadsregionen

Sedan år 1998 har det i Nollvisionens fotspår startats ett utvecklingsprogram i Sverige som syftar till att omvandla gamla 13 meters landsvägar och motortrafikleder till mötesfria. Implementeringen var tänkt att påtagligt reducera antalet mötes- och omkörningsolyckor samt singelolyckor med svåra konsekvenser i form av svårt skadade och dödade utan att försämra trafiksäkerheten i övrigt. Syftet med denna studie är att göra en effektmätning av de mötesfria vägarnas införande i Karlstadsregionen samt att göra en sammanställning av de olycksrisker mötesfria vägar omfattas av. Frågeställningarna som används i studien är:- Har det blivit säkrare på vägarna sedan implementeringen av mötesfria vägar i Karlstadsregionen?- Hur sker olyckor på mötesfria vägar inom Karlstadsregionen? För att beskriva hur olyckor sker på mötesfria vägar inom Karlstadsregionen har en deskriptiv analys tillämpats som grundats på de beskrivningar av händelseförlopp som dokumenterats i STRADA och CORE, mellan åren 2010-2013.

Kontroll av zinkskikt på monterat räckesmaterial

Kontroll av zinkskikt på monterat räckesmaterial som görs ute i fält saknar en fastställd metod. Zinktjockleken har ett minimum tjocklekskrav enligt den svenska standarden ISO 1461:2009, som bestäms av dimensionen på ståldetaljens tjocklek. Trafikverket begär att med hjälp av detta examensarbete kunna begränsa antal mätningar på plats, då kan det ta allt för mycket tid och arbetsresurser i fall det skulle behövas kontroll av väg-och bro räckesanläggningar från beställaren.Sannolikhetsläran och stickprov i statistik hjälper oss att begränsa antalet mätningarna på skyddsanordningarna som görs ute i fält. Med hjälp av normalfördelning kommer man fram till den efter strävade metoden, som med en rimlig arbetsinsats ger en rättvisbild av skikttjockleken på monterat räckesmaterial.Vid variation av varmförzinkaren på vägräckesanläggningar undersöker man varje leverantörs räckesdel för sig, alltså man mäter zinktjockleken på en varmförzikare för sig, kontrollerar zinkskiktstjockleken på de och tar slutsatser sedan går man vidare till nästa tillverkare. Om vägräckena är mindre än 30 stycken mäter man zinktjockleken på respektive anläggning.För beräkning av zinkskiktstjockleken på monterad räckesmaterial börjar man med 30 mätningar och användning av den centrala gränsvärde satsen för att approximera till normalfördelning och analysera resultatet.Det slutliga resultatet av examensarbetet är ett Excelprogram med inmatade formler.

Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

Mjukvaruplattform för riggstyrning

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Hur gott är gratis? : En studie om gratisekonomi

The purpose of this thesis is to identify the most important establishment criteria for companies whointend to do a new establishment. There are differences between regions regarding attraction on startup.Some regions have few new businesses while others continuously expanded its activities in variousfields. The biggest focus on the thesis is the Gävle- Borlänge region where MellansvenskaHandelskammaren is active.Mellansvenska Handelskammaren saw a need for the assignment after the magazine ?IntelligentLogistik? ranked the Gävle region at 15:th place and Falun/Borlänge at 20:th place in the list over thetop 25 best logistics locations in Sweden. This made them wonder what could be made to develop intoa better area with more amenities and a better place in the ranking of the magazine.

Konsten att skapa utrymmen : Förbättringsmöjligheter inför framtida överdäckningsprojekt för att främja samhällsutvecklingen

En hållbar samhällsutveckling beror på tre faktorer; naturen, människan och samhället. I dagens läge vill människan minimera de påfrestningarna som miljön och omgivningen utsätts för. Det är därför viktigt att se över hur resurserna utnyttjas. Ett bra exempel på detta är att befintliga trafikleder inom tätbebyggda städer byggs över, sådana projekt kallas överdäckningar. På detta sätt skapas både byggbar yta och negativa effekter av trafikleder minskas inom tätbebyggda områden.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

Strategisk och taktisk planering samt länken där emellan : analys av planeringsprocessens genomförande vid SCA Skog

To effectively manage a forest resource for both economic and other values good planning is required. The problem is complex since you want to know which forest to cut and when. Often a hierarchical planning structure is applied, including strategic (long-term), tactical, (medium-term) and operational level. Today SCA Forest is one of few forestry companies in the northern Sweden with an integrated forest wood supply and industry. The goals of the company are to supply their own industries with wood and to manage the resources of the forest through a long-term perspective with satisfactory profitability.

Lodgepole pine - stability after thinning

SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.
