Flyt tillsammans : Emotionell gemenskap i kooperativa spel
Studien undersöker känslomässiga reaktioner vid kooperativt spelande, vilka som är gemensamma för båda spelarna och hur de påverkas av hur svårt spelet är. Arbetet utgick från studier av spelares emotionella reaktioner på spel och teorierna om Flow. Spelet Sanctum användes i en serie tester där mätningar utfördes på två spelare med hjälp av rapportformulär, pulsmätare och hjärna-till-datorgränssnittet Emotiv EPOC. Studien fann att spelarna ibland upplevde samma känslor när de spelade tillsammans och att den ökade svårighetsgradens huvudsakliga effekt var att förändringarna i känslorna blev skarpare och större. Det tycktes huvudsakligen vara motgångar som splittrade spelarnas upplevelser.

Everyday life mobility of elderly people ? opportunities, restrictions and sustainable urban visions aim to examine and describe elderly people?s movement patterns, their opportunities and restrictions of reaching high mobility and accessibility, and their attitude towards various sustainable urban visions. This paper is based on an approach of time-space geography as it covers the topic of movements in time-space, explained and developed using the concepts of mobility and accessibility. To examine elderly people?s attitude towards sustainable urban visions, this paper also takes approach on theories such as New Urbanism, mixed-use and the compact city.The method used in the study is an interweaving of a time geographic diary and qualitative interviews, where the respondents are six retired people between 68 and 77 years old living in Gothenburg city.
Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
Flödesoptimering på sjukhuslaboratorium: En praktisk implementering av lean
This study has investigated the possibilities of implementing lean in a division of a hospital in Stockholm. The goal was to reduce the lead time for the patient to get his diagnose by implementing lean in the two production flows of this division. In order to accomplish it, a complete map over the value stream has been done. With the help of the value stream map and lean theory a list over the processes in contradiction with lean has been made. Finally propositions to implement lean and by this way reduce the lead times in this stream have been made out.
Transport av volymelement : Förutsättningar ur ett företags perspektiv
Building with volume element is relatively new and has started to increase more and more. The regulations that exist to regulate and determine how the transports of volume elements are to be conducted are diffuse and not very well adjusted to address the issues with transporting volume elements. Today there are a number of instances that a company has to turn to in order to get a somewhat different view, what regulations say and interpret it in order to know what applies and not applies regarding the transportation of volume elements. regulations. The rules that are in place make it tough for the volume element producing companies to develop and continue to be active on the market.

TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
Transportbranschen : Miljöanpassning utan negativa företagsekonomiska konsekvenser, är det möjligt?
This paper is about how transport companies in the future will be able to adapt their activity to an environmentally sustainable development without the effect of negative company economic consequences. Today, the environmental threat is a global problem and knowledge about that effluent of carbon dioxide have a negative impact on the climate is generally known. A transport system that works well is important for Sweden, but the sector has a negative impact on the environment. Regulation and legislation for increased environmental requirements often meets resistance and fear that the work will be hampered by increased costs for environmental work that can lead to an international decrease in competitiveness. The transport companies have outside pressure from the society to do something about the environmental issue, however the companies? customers are not ready to pay a higher price for environmental work.
