En trend i den teknologiska utvecklingen på senare tid har varit att skapa en ökad rörlighet hos användaren. En bidragande faktor till detta är den snabba förbättringstakten hos de smartphones som i större utsträckning har funktionalitet som tidigare endast datorer hade. Detta har i sin tur förändrat de förväntningar slutanvändarna har på tjänsters tillgänglighet, vilket har lett till att produktiva mobila applikationer, appar, har funnit sin plats i vardagen.Denna studie är genomförd på Scanias Fleet Management-avdelning som erbjuder en webbaserad tjänst där åkerier kan administrera, övervaka och följa upp sina fordonsflottor. Syftet med studien var att undersöka om en förlängning av Scanias existerande webbtjänst till den mobila sfären är rätt steg att ta och vilka organisatoriska och tekniska utmaningar en ingång inom apputveckling ger upphov till. För att bemöta denna problematik har en omfattande kvalitativ undersökning genomförts där tre huvudgrupper av respondenter har intervjuats: jämförbara företag som har ställts inför liknande utmaningar, apputvecklingsföretag som har förståelse för appområdet samt Fleet Management-tjänstens existerande användare.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

An ever-increasing population, urbanization and visions towards sustainable cities clarifies the need of densification. When densifying existing urban areas adding storeys could serve as a residential densification, which would also meet the market demand for centrally located apartments. An increased understanding of the potential of vertical densification gives way to the aim of this thesis to increase the amount of centrally located housing.This thesis provides knowledge of adding storeys and how property owners can identify opportunities in their existing building stock.The first question, What kind of residential densification takes place in Sweden today? highlights ways of residential densification; development of brownfields, infill and adding storeys, where adding storeys is what this thesis then focuses on. The result came through a literature review that also clarified important factors when adding storeys.

Denna rapport beskriver resonemanget kring framtagandet av en modul som tillåter användaren att, på ett lättanvänt sätt, skripta beteenden hos en redan existerande grafikmotor. Arbetsprocessen beskrivs steg för steg med definition av vad ett skript är, vad som ska kunna gå att skripta och vilka övergripande krav som ställs, design av tekniska lösningar, design av syntax, testning och till sist resultat. Resultatet varierade på de olika punkterna. Den underliggande tekniska lösningen blev lyckad då den uppfyllde kraven på modularisering, robusthet, flexibilitet och prestanda. Ur en tillämpbarhetssynpunkt blev resultatet även här tillfredsställande eftersom det visade sig vara fullt möjligt att skripta kloner på de tre försöksspelen (SkiiFree, BreakOut och Space Invaders) på ett sätt som kändes bra och rättfram.

In order to evaluate different afforestation methods for exposed heath lands a field experiment was established in Mosfell on southern Iceland in 1989. The trial comprised six different site preparation methods (control, herbicide application, tree shelters, patch scarification, TTS trenching and mounding). In total 960 container seedlings (1+0) and 960 Nisula roll transplants (2+1) of lodgepole pine were planted. Various planting positions (furrow, hinge, no site preparation (control) and on top of mounds) were tested within the site preparation treatments. This study involves renewed measurements and analyses of the trial.After 19 years the overall survival was 51,7 %.

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

The purpose of this paper is to survey the textile based proto-industrialism in Sweden in the middle of the 19th century. This case study is founded upon Anders Hansson?s pre-industrial textile production at the estate of Mölneby, Östra Frölunda in the rural district of Kind in the province of Västra Götaland.Account books from the year 1853 related to Anders Hansson?s wool fabric manufacturing have been looked into and categorized using a quantitative research method. The research has also been supplemented with a number of interviews.The result of the survey shows that Anders Hansson?s business activities fit into Mendel?s theory of proto-industrialists at a practice level.By collaborating with a merchant in Gothenburg the fabrics were traded in unknown markets, as well as in more familiar neighbouring districts.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Carbon dioxide in the atmosphere contributes to the greenhouse effect, which is essential tolife on our planet. Furthermore, it plays an important part of the photosynthesis andrespiration of the world?s organisms. Since the start of the industrial revolution the amount ofcarbon dioxide in the atmosphere has increased exponentially. The main source is theextensive burning of fossil fuels.

Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties.  There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04?s and Eurocode 2?s demand for surface roughness.  A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not.                       The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.The method used to identify the shear capacity is called L-shaped Push-Off Test.

Objective: The aim of the study is to describe pupils' understanding of the mathematical concept of function. How do pupils define the concept of function? What images of the concept of function evoke when they solve tasks, which involve identifying and constructing functions?Theory: A student's thinking about a mathematical concept depends on more than just the formal definition of the concept; therefore Tall and Vinner introduce the term concept image to describe the role cognitive structures play when students learn about concepts. The cognitive structure includes all mental images, associated properties and processes that an individual associates with a given concept. According to Sfard, an individual's understanding of mathematical concepts may have different character: an operational conception, where a concept is conceived as a process and a structural conception, where the given concept is conceived as an object, that is, as a whole.Method: 16 pupils at the Science Program at two different upper secondary schools inSweden answered a questionnaire on the mathematical concept of function.
