Prioritering av icke-funktionella krav i praktiken : Ur ett agilt perspektiv
Requirements management is an important part of the software development process. The success of a project may depend on how this is handled. Even though several research studies indicates that more attention should be paid on non-functional requirements, the primary focus in practical projects still regards identifying functional requirements. Especially the prioritization of the non-functional requirements has been proven to be of great importance for the success of a project.This report investigates basics in agile requirements management involving opinions from experts from a software development company. This is done with help of existing literature and interviews with key actors involved in prioritization at the company.
Jämförelse mellan sådd och naturlig föryngring av tall i Härjedalen
The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.
Mind Touch-en studie om positionering av Functional Food produkter i konsumentens medvetande
Syftet med uppsatsen är att analysera och studera hur man skapar en position för Functional Food produkten i konsumentens medvetande, det vill säga undersöka vilka positioneringsstrategier svenska Functional Food produkten har, och vilka marknadsstrategier företagen har använt för att skapa önskad position i konsumentens medvetande. Genom fallstudier undersöker och analyserar vi hur företagen har lanserat och positionerat sina Functional Food produkter mot intressanta marknadssegment. Syftet med fallstudier är att exemplifiera vilka positioneringsstrategier Unilever och Skånemejerier använt sig av och under vilka förutsättningar de har lyckats nå en position med sina Functional Food produkter på den svenska marknaden. Det empiriska materialet har kompletterats med expertintervjuer. Den teoretiska referensramen utgörs av tre teoriområden, Innovation, Diffusionsprocessen samt Positionering, där vi fokuserar på skärningspunkten mellan dessa.
Cassava as an additive in biomass fuel pellet production :
In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).
The impact of store atmospherics and consumer attitudes on in-store behavior ? What determines the buying decision of functional food?
Thesis purpose: The aim of this paper is to extend the knowledge of what influences the purchase decision of functional food in the store. By applying the M-R model in a new setting - the dairy department in grocery retailing in Sweden - and adding variables related to health attitudes, the aim is to contribute to existing research concerning in-store purchase decision making and store environment as well as consumer attitudes. Methodology: This thesis employs a quantitative strategy with a deductive approach and data has been collected with questionnaires. Theoretical perspective: Environmental psychology serves as an overarching framework where, more specifically, certain aspects of store atmospherics and some variables concomitant to health attitudes provide the theoretical base. Empirical data: The empirical data consists of customer purchasing a functional food product, Proviva, and this is contrasted with a test group, Bravo.
Syntes av hydroxyapatit/ nanocellulosa kompositer
Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.
Underhåll av Turbomin 100
AbstractStudents at Mälardalen University have long performed their lab on a small turbojet engine in the course Aircraft Engine Technology. Since 2011, the engine has been dysfunctional. This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Flottledsåterställning i norra Sverige: : effekter på habitatkvalitet och populationstätheter av juvenil öringar (Salmo trutta L.)
In an effort to evaluate the effects of restorations of float ways on population density of stream dwelling fish in relation to the changes in habitat, I studied the physical habitat restored and channalized sites and their population density of brown trout (Salmo trutta L.) in three streams in the municipality of Sorsele.
The differences between the channalized and the restored sites where most noticeable regarding substrate which where generally coarser in the restored sites. The analyses showed that the proportion of habitat that where suitable to the age class 0+ where significantly lower in the restored sites compared to the channalized sites. Regarding age class ?2+, no statistical differences in habitat quality were found.
Hamburgare eller bajs? : en fallstudie om en funktionshindrad elevs undervisning i idrott och hälsa på en särskola
A child with functional disorder getting close to starting school has different types of schooling to choose between. Parents and the school of the matter have to agree in consultation. I use the conceptions included and segregated schooling to show different ways attend school. By included education I mean that all students with as well as without functional disorder in a group shall be completely comprised in the situation and not be separated from the group by individual exercises (Fors 2004). A segregated schooling is often pursued in special school where all the students have functional disorder and the education usually takes place in separate buildings (Emanuelsson 2001).I have completed a qualitative case study of a boy who is 14 years old and has the functional disorder Down?s syndrome and has been placed at a special school his entire schooling.
Visuell utvärdering av frekvensmodulerat raster på obestruket papper.
This thesis investigated if a combination of increased under colour removal (decreasing the total ink limit), normal andincreased density and modern FM-screening could be used to provide a visually better print on uncoated and coated paperin comparison with AM-screening using the same conditions.Two different test groups (one with graphic background, the other with no graphic background) were asked to a visuallyassess the quality of the prints presented in a pair comparison using a reference image.The results show that the FM-screening did not obtain any significant visual difference in comparison with AM-screening,regardless of paper types and density levels. In general however, prints on coated paper were graded higher..
"Att orka vara själavårdare" : En jämförande studie av copingresurser i pastoralkliniskt och kontextuellt själavårdsparadigm.
This study aims to find coping resources in two different paradigms of pastoral care using coping theory from the psychology of religion. The intention is to find coping resources that are functional coping strategies to help priests and chaplains in their work with pastoral care. The research questions are: What coping resources can be found in the pastoral clinical paradigm and the contextual paradigm? What are the differences and similarities? The method used is template analysis style where the theories form a framework for the material used to analyse in this study. The theories used for this study are religious coping theory and pastoral care theory.
Kundrelationsarbete i den industriella försäljningsprocessen
The purpose of this thesis was to examine how the build-up of customer relations can be characterized at the end of the industrial selling process and how companies engage their cross-functional selling teams into this relationship building effort. Through a case study of Omega, a multinational company engaged in the selling of products of an industrial character, it was revealed that the build-up and maintaining of the customer relationship is of acute importance, as it presents the company with a window of opportunities. Through its relationship with the customer the company can be able to sell other products, which are related to the original purchase made by the customer. For the company?s competitors the established relationship might also serve as a barrier when attempting to enter the market or increase market share.
Tvärfunktionell produktutveckling : - En utredning på Scania om samverkan mellan konstruktörer och produktsamordnare
The role distribution between designers and product coordinators and the system support between these roles are adapted according to the method of working that product models primarily are created for production and after sales market. At the same time models are also created to support a cross-functional way of working. This means that product structures exists on paper and as CAD-models before they are created in Scanias PDM-system environment which leads to unnecessary work and to information not being shared as early as it should be possible.A theoretical study has been performed with the purpose of understanding the problems and to create a foundation for improvement suggestions. Representatives from both roles have been interviewed together with other individuals with insight in the collaboration. A minor study concerning the roles of interests? collaboration at Volvo CC was also performed to be able to relate the study to another company.
Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
