Self-driving cars are soon to become a reality to the commercial market. A self-driving car does not have a human operator, which enables some interesting characteristics. The main benefits are considered to be:The number of accidents and traffic jams should be reduced.Enhanced comfort.Energy usage could be decreased while capacity could be increased.This study concerns the causes for improved energy efficiency. The reason for improved energy efficiency is mainly because of the variation in terms of acceleration, braking and distance holding are reduced. The vehicles are more intelligent and can work together as a unity.

Bakgrund: Att utveckla och förbättra organisationer genom effektivare användning av de resurser man har till förfogandet har blivit allt mer betydelsefullt under de senaste decennierna. Genom fokusering kring de aktiviteter som tillför värde hos kunden i slutprodukten kan företag reducera och eliminera oönskade slöserier inom tillverkningsprocessen. Ett verktyg som utvecklats och används för att eliminera dessa oönskade aktiviteter så som lagerhållning är Value stream mapping (VSM). Problemformulering: Hur kan man identifiera slöserier samt dess förbättringsmöjligheter för att möjliggöra en högre produktionskapacitet genom frigörandet av anläggningsyta?¨ Syfte: Genom användandet av VSM som modell, identifiera slöserier och kostnadseffektiva förbättringsmöjligheter. Metod: Denna fallstudie har utförts på ett företag som arbetar inom metallindustrin. Större delen av datainsamlingen har tagits från företagets egna dokumenterande data samt intervjuer med anställda och observationer under de besök författarna genomförde. Slutsatser: Genom att använda VSM som en modell har författarna lyckats identifiera fallföretagets största faktorer till slöserier samt ge förslag och underlag till framtida förbättrings implementationer av förbättringsstrategier.

Denna kvalitativa motivationsstudie utfördes på åtta svenska toppsäljare och utgick i från Vallerands hierarkiska modell om inre och yttre motivation (1997) och även från Czikszentmihalyis teori om flow (1990). Syftet med studien var att ta reda på vilka motivationsfaktorer som förenar toppsäljare. Toppsäljarna intervjuades enskilt genom en semistrukturerad intervjuguide. En tematisk analys utfördes på utskrifterna från intervjuerna och analysen undersöktes utifrån tre huvudkategorier: inre motivation, yttre motivation, och flow. Resultatet visade att toppsäljarna hade en stark inre drivkraft att utvecklas, att nå egna mål och uppnå positiva känslotillstånd av själva utförandet.

Den här C-uppsatsen har gått ut på att göra en processkartläggning på återuppbyggnaden av Vivallaskolans bollhall som har brunnit ner under slutet av oktober 2010. Utifrån processkartläggningen har det gjorts analyser och observationer på aktivitetsflödet. Där framgår det vad som har gått bra och mindre bra. Till det som har gått mindre bra har förslag till lösningar tagits fram. I dessa lösningar ingår metoderna: PDCA (s.21), BIM (s.21) och Ishikawadiagram (s.21), som tydligt visar förbättringsåtgärder.Processkartläggningen och lösningsförslagen har tagits fram utifrån observationer i form av besök på arbetsplatsen samt läsning av litteratur och elektroniska källor.

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

The aim of this Master?s thesis is to investigate the meaning the reading group of the public library has to a number of users. To fulfill the aim the following three questions have been formulated: 1) What do a number of users expect from the reading group of the public library? 2) Which approach/attitude or approaches/attitudes do a number of users have to reading and to talking about reading? 3) How do a number of users experience the ongoing reading group?The research is founded on qualitative interviews with five users that take part in three different reading groups in public libraries. The theories that are used is the theory of three so called strategies - the pragmatic, the traditionalistic, the emancipatory ? and the theory of flow.

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and  to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.

För att göra informationen tydligare för en larmoperatör som sitter och övervakar larm som kommer in från ett antal olika nätverkskomponenter så har vi skapat ett system som förser larmen med extra information, kallad Context Type, så att vi kan presentera larmen på ett enklare sätt. Vår informationsberikning, även kallad mappning, är utbyggbar för att möta kravet på framtida utveckling. En webbaserad klient skriven i JavaScript är skapad för att presentera larmen på ett nytt innovativt sätt som är baserad på context typen istället för larmobjektet. Mappningen är skapad med hjälp av Python kod och begränsas av att endast använda textfiler som datakälla och webbapplikationen är endast utvecklad för webbläsaren FireFox samt att visningsintervallet för larmen är begränsat till ett dygn med entimmesintervaller. Mappningen var långsam då vi använde oss av regular expression.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

This thesis have been performed at Sweco Position in Jönköping. The work was split into two, where one part included an investigation regarding the possibility of developing a cross-platform GIS (geographic information system) with HTML5 and CSS3. A prototype would also be developed within this part.The second part included development of a cross-platform GIS for a client to Sweco Position. The client operates in the forest sector and had already an existing solution, with many problems. The client required an application with delimited functionality and which was not bound to a specific hardware.As the client users often were located in areas with limited Internet access, one additional requirement was that there would be some offline support.The students handle subjects within development of GIS, for example map projections, map services and mapping libraries.The application came to be developed in HTML5 and ASP.net.

The aim of this thesis is to study Stadshuskällaren?s operational processe flow and identify their operational characteristics. The uniqueness of Stadshuskällaren is that they are breaking the law of trade-offs regarding volume/variety, much like Toyota managed to do ? which spawned the entire field of research of the ?Lean Philosophy?. In the thesis the characteristics we identify through analysis, which enables Stadshuskällaren to break the trade-off, are compared with the principles of Lean service theory, which ultimately stem from Toyota.
