Fisk, fågel eller mittemellan? : En studie av tre multiprojektmiljöer
Background: A great part of all projects within Swedish industry are conducted in a multiprojectenvironment, which means that several projects are performed simultaneously. The research within the field of project management is though focused on single projects. Projects are highly dependent on the context in which they are conducted, although the organization of the multiprojectenvironment is only partly explored. Furthermore is the research within the project management highly concentrated on standardization of the project work. The question is whether this implies to the basic advantages with the project-oriented organization, which is flexibility and creativity? Purpose: To describe and obtain an understanding for the multiprojectenvironment regarding management control and organization.
Nätnyttomodellen och dess inverkan på ett distributionsnät - En studie i samarbete med Härryda Energi AB
This report is intended to give an insight in the Network Performance Assessment Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..
Undersökning av optimeringsalternativ för elektrostatlackering
This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..
Undersökning av artikulation, nasalitet och förståelighet hos 16- och 19-åringar födda med isolerad gomspalt
This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.
Marknadsföring av folkbibliotek i teori och praktik ? En studie av marknadsföringsarbetet på två folkbibliotek
The competition for people´s attention becomes harder and harder. If the libraries want to continue to attract visitors it´s important that their business is promoted. The purpose of this thesis is to in-vestigate how two public libraries work with marketing. The study is based on a marketing model, introduced by Philip Kotler and further developed by Eileen Elliott de Sáez. Kotler believes that marketing is a social process and that everything can be promoted.
Pojkars och flickors brinnande intressen : En analys av 10 elevtexter ur ett genusperspektiv
The main purpose of this study is to analyze texts written by pupils during the national test in the subject Swedish for grade 9 in order to identify and illustrate how they have met the instructions for the writing task including genre. The texts have been analyzed using Palmér & Östlund-Stjärnegårdh?s (2005) model for student text analysis. This model has been supplemented by studying word and sentence length, as well as indexes for level of readability (LIX) and word variation (OVIX) in order to illustrate possible differences in a gender perspective. The results of this study are in line with previous research, as the girls? texts are longer and more descriptive, while the boys? texts are shorter and show a wider range of word variation.
Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell
The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.
An enriched arena for lamb - anticipation behaviour before entering the arena, effects of skipping the anticipation phase and effects of being denied access to the arena
This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.
Identifiering av samband mellan kravinsamling och kunskap
The stakeholders for requirements elicitation need to be identified at an early stage and their knowledge is the basis for what is to become a requirements specification. Just because a stakeholder holds a lot of expertise and knowledge it does not mean that the stakeholder can communicate the knowledge in a clear way. Validation of knowledge means that knowledge is valued and recognized in a structured way. People and organizations can evolve by exchanging knowledge, experience and skills. The purpose of this study is to increase the understanding of knowledge management between requirement elicitation and external stakeholders.
Service som Strategi: Influeras Styrningen av Service eller Service av Styrningen?
The purpose of this thesis is to examine and analyse which effects a service strategy has on the control system of an organisation. The thesis takes a service perspective, and it is assumed that a service strategy gains competitive advantage and that the goal of the service strategy is to increase the customers? satisfaction level. A qualitative in-depth case study was performed on a Swedish beauty company. The organisation?s vertical structure was examined, from central to local level.
Välfärdsstad i förändring-Idéburna organisationers roll i dagens socialpolitik
The Swedish society and welfare model are under constant changes anddevelopment. One of the core areas in this welfare model is the social policy. By analysing the changing role of the organizations in the civil society on a local level with a theoretical typology changes in the roles can be noted. These changes can with a model for ideal types raice questions about bigger changes concerning issues of legitimacy and accountablility. I uses qualitative method including interviews with actors on the local level, earlier reseach in the field and public documents.
BIM på Trafikverket : Förslag till en utvidgad investeringsprocess
2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.
Paddan blir prins - när fast pris inte finns. En studie om prismodellen Pay-What-You-Want applicerad på en ny produkt.
The purpose of this thesis is to investigate the two new phenomena; the pricing model Pay-What-You-Want (PWYW) and the launch of daily newspapers in the iPad. A quantitative study was conducted in order to examine what would happen if the PWYW-model where to be used by a daily newspaper for its iPad product, and what this would signal to consumers about the brand in terms of brand association and brand attitude. Furthermore, we have investigated which of these factors that are affecting willingness to pay in this PWYW-situation. Moreover, a secondary purpose was to test the two possible presentations of the digital newspaper in the iPad; Product and Access ? and how the results differed between these two.
JCJ-Metoden : En differentiering av Scanias WACC
Scania?s discount rate - the return requirement of investments - refers to Scania?s WACC or weighted average cost of capital. The capital markets return requirement on equity and the credit market interest cost of borrowing is weighted to become the single discount rate, the WACC. The purpose of this study is to investigate which asset pricing model of APT and CAPM Scania should use in their WACC calculations. The company now uses a group WACC of 11 percent which is used in all company levels.
Biljardproblem
Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.
