Internkommunikation och beslutsprocesser inom Åtvidabergs FF : En kvalitativ fallstudie av Åtvidabergs FF

AimThe purpose of this study has been to help Åtvidabergs FF to find development opportunities by reviewing the internal communication and decision making process within the organization. In this study we have used two models, Johari window and Administrative man.Our study has two main questions. The questions at issues are:? Can Åtvidabergs FF with help of the communication model Johari window identify how the internal communication can improve?? Can Åtvidabergs FF use the Administrative man as a decision model?o Will the use of the model Administrative man lead to better decisions will be made?MethodWe have made a qualitative case study in a positivistic spirit. Data has been collected through half structured interviews.

Hållbarhetscertifiering av stadsdelar : En studie av BREEAM Communities praktiska tillämpning i svensk stadsbyggnad

In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.

Kommunikation med barn: Skapandet av en bilderbok : En litteraturundersökning om bilderboksriktlinjer samt tillverkning av en bilderbok

Many people believe that the analogue picture book is a dying media due to the increase of digital media. Contrary to popular belief, the publishing of children?s book in Sweden is continually increasing, which makes mapping the field quite significant. But to regulate the creation of a children?s picture book is problematic, because one does not want to impede the personal style of the writer or the illustrator of the children?s book.If the children?s book creator has an understanding of how to better communicate with children, the children?s book might have a grater impact on the child.

Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.

Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.

Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Uterummet i undervisningen : en läromedelsanalys inom biologi

This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.

This master degree paper is exploring a part of KB?s digitisation of those collections. It deals with the questions about what the KB had chosen for digitisation, why those choices were maid and who is responsible for making these decisions. The paper will also for example seek out different patterns and trends in the information.

Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

Analys av det nordiska kraftnätets påverkan på det svenska elspotpriset.

During the last few years, there has been a lot of debate regarding the price ofelectricity on the Swedish market. According to a recent survey from Sifo, anon-bias governmental institute for consumer research and testing, the priceof electricity is what worries Swedish households the most. An investigationof the eciency of the Nordic power grids inuence on the Swedish spotprice is therefore both relevant and valuable. Three quarters of all electricityproduced in the Nordic region is traded at the Nord Pool Spot power market.This survey examines how much of the variation of the swedish spot pricecan be descried by the variation of the nordic system price and how much iscaused because of ineciencies in the power grid. Primarily, linear regressionwith adjustments for endogeneity and heteroskedasticity has been used in orderto analyze data obtained mainly from Nord Pool Spot and Vattenfall AB.The results show that the variation of the system price can account for all butabout 40% of the variation in the Swedish spot price.

Konstruktion av datainsamlingskort för mätsystemet COMET

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Produktspårning med RFID : Konceptutveckling och utvärdering

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Re-design på uppdrag av Spotify : Framtagning av designförslag för ny visningsvy för internprogram baserat på kontextuella intervjuer

Spotify is a music service that offers on-demand streaming and is available in several countries worldwide. As the company and the interest for it grows, more and more parties are involved and those involved, including the record labels want to control and get an overview of their products. They want to be able to see, for example, when a product is available on Spotify and in which countries.Spotify is in May 2013 in process of developing a to be used by administrators on Spotify in order to meet the record labels with the information requested. The new software intends being used by administrators but also by the record labels so that they will be able to overview their products availability.We were asked by one of the developers to conduct user interviews and tests to result in a design proposal on how the display page of information about a product could be visualized more clearly so that it suits both record labels and employees at Spotify. The results of our contextual interviews were translated into a prototype with two display pages.

Cupsystemet : En kvalitativ fallstudie av en mobil webbtjänst

The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments.

Pluralismens utmaningar - En teoriprövande studie med Belgien och Schweiz.

This thesis is set out as a testing of the crosscutting cleavages theory on twocontemporary cases. The aim is to test the explanation process of the crosscutting theory applied to the political and social situations in Belgium and Switzerland and furthermore to examine potential conflicts in pluralistic states. Our main questionis: How can the crosscutting cleavages theory explain the different outcomes ofsocial coexistence, even with the states numerous similarities? We have examined the two federal states through their social divisions of language, region, religion and socio-economy. Our findings show that both Belgium and Switzerland possess divisions in the above mentioned variables, which in most cases are cumulative structured.

Att förbättra lärbarheten : en användabarhetsstudie på webbaserade system

Syftet med rapporten är att belysa lärbarhetsaspekten som en del av användbarhet. Diskussionen grundar sig i ett större projektarbete om BG Faktura, en produkt från Bankgirocentralen. Bankgirocentralen gav i uppdrag att ta fram metoder, testanvändare och att samordna en användbarhetsanalys på BG Faktura. För att få fram användbarhetsproblemen genomfördes ett flertal utvärderingar; en heuristisk utvärdering, en kontextanalys och empiriska användartester. Då utvärderingsmetoderna resulterade i många användbarhetsproblem skapades en prototyp med modifieringar av BG Faktura enligt de rekommendationer och förslag som kommit fram i testerna.
