In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..

This exploratory thesis uses qualitative research to investigate how digital music is beeing packaged. The main study consists of 11 deep interviews with key representatives of the digital music industry in Sweden. These are (record companies) EMI, SonyBMG, Universal, Warner, (DSP) InProdicon, (mobile operators) 3, TeliaSonera and (cell phone producer) SonyEricsson. Packaging is a concept of marketing that has specific implications depending on which good or service that is being packaged. Packaging occurs at different levels in the production chain.

This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.

This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

The purpose of this study is to highlight some aspects of the increased usage of tablets in preschool environments by answering the questions: what does the tablet become in the preschool environment, how much freedom does the children have over its usage.To answer these questions a series of observations were made at two different preschools. The observations were then complemented by interviews with teachers at the same preschools.This qualitative study focuses on some of the didactic questions regarding the tablets, based on a theoretical framework that is within the design-oriented perspective; which addresses the children's? autonomy, the institutional framework and affordance.Our conclusion is that the tablet?s introduction in the preschool has helped the teachers in numerous parts of their documentation, but we can also see that the children's opportunities to make choices regarding the tablet are more limited than with any other resource on the preschool. In our results we also see that when the children get access to the tablet they receive a learning experience, which among other things, strengthens their language skills and their social interaction with each other..

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Current technology offers many possibilities for remotecommunication. Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.

The outset of this thesis is to raise questions on how we design for the mobile context and the capabilities of smartphones. Not only the presentation but also the use of input and interaction between a service and a user.This work evolves around sign up forms and answers the question: How does the sign up process affect the holistic perspective of a digital service regarding usability and user experience? This thesis consists of a case studies, and design experiments conducted on Twitter, Instagram and Randos sign up processes to explore if and how the usability, and the user experience could be affected and im- proved.This concluded some important aspects to be considered when designing sign up forms for a digital service.The usability, and the user experience is not only affected by user interaction, and the choice of input method but it?s also affected by which data the service is requesting, and more important; if that data is motivated to request by the service..

Near Field Communication (NFC) är en teknik som möjliggjort utvecklingen av vardagliga betalningar med hjälp av mobiltelefonen. I Sverige är betalningar med NFC-tekniken i mobiltelefoner fortfarande i introduktionsfasen. För att denna teknik ska ha möjlighet att fungera som ett komplement till redan befintliga betallösningar, granskas därför möjligheten för NFC-teknik som betallösningsmetod med inriktning på säkerhetsaspekter.Syftet med uppsatsen är att granska säkerhetsaspekter för NFC-teknik som mobil betallösningsmetod samt analysera dessa aspekter för att få djupare kunskap för NFC-teknologins möjligheter. Kunskapen har erhållits genom en litteraturstudie samt kompletterande av en intervju för att få bredd i informationsbehandlingen.Resultatet av studien visar att NFC-teknologin som betallösningsmetod kan påverkas av ett antal säkerhetsaspekter. För att NFC-tekniken skall nå en bredd i marknaden måste flertalet aktörer samarbeta för en standardisering i användandet av tekniken..

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

The purpose of this paper has been to reach a greater understanding in how moral inflicts social workers way of handling everyday situations. In what way, if in any way, moral comes to play a part in the making of decisions. In order to reach this understanding we have interviewed two different groups of social workers which we also later on came to compare . One of the groups contained six interviewees and the other group contained five interviewees. Both of these groups were in the ages between 27 ? 52.To shed some light over this phenomenon did we use two theoretical perspectives, first Kant?s morale theory and second, consequentialistic utilitarism theory.As a result from the interviews we?ve made, we came to an understanding that the meaning of morale and in what way it can be applied in the everyday work differs between these two professional groups.
