Second screen - För Tv-serier
Today it is not unusual to use a secondary screen to accompany a primary screen. The possibility to integrate these two in the form of an application for the secondary screen have long been possible but have not been developed to full potential. This thesis aims to study the use of the extra information and functions this type of application would make possible and how this type of application could be used.For this study a prototype-application including a real time newsfeed and a static menu for a specific episode of a Tv-series was created based on the information collected in an online survey. The application was tested on a number of people who got to evaluate the experience in short interviews and were given the possibility to recommend changes in the application.The result after the study showed the people where torn about what kind of information would best fit the application but showed over all that a dynamic newsfeed with information continuously updated with the episode where most appreciated. The problem with the difference in interest around the categories would be solved first and foremost by the application being configurable so that every single user has the possibility to choose which kind of information to be updated in the newsfeed.
Verifikation av verktyget aspect analyzer
Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.
Ledtidsanalys på Peltor AB med logisk gruppindelning på elektronikprodukter
This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product.
Utvärdering av mötesfria vägar : Analys av olyckor på mötesfria vägar i Karlstadsregionen
Sedan år 1998 har det i Nollvisionens fotspår startats ett utvecklingsprogram i Sverige som syftar till att omvandla gamla 13 meters landsvägar och motortrafikleder till mötesfria. Implementeringen var tänkt att påtagligt reducera antalet mötes- och omkörningsolyckor samt singelolyckor med svåra konsekvenser i form av svårt skadade och dödade utan att försämra trafiksäkerheten i övrigt. Syftet med denna studie är att göra en effektmätning av de mötesfria vägarnas införande i Karlstadsregionen samt att göra en sammanställning av de olycksrisker mötesfria vägar omfattas av. Frågeställningarna som används i studien är:- Har det blivit säkrare på vägarna sedan implementeringen av mötesfria vägar i Karlstadsregionen?- Hur sker olyckor på mötesfria vägar inom Karlstadsregionen? För att beskriva hur olyckor sker på mötesfria vägar inom Karlstadsregionen har en deskriptiv analys tillämpats som grundats på de beskrivningar av händelseförlopp som dokumenterats i STRADA och CORE, mellan åren 2010-2013.

Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011
Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).
Affärsmodeller och Strategier i Apples Appstore
Apple has since their launch of the Iphone series created a billion dollar business with the market place Appstore. Third-party apps have disrupted the mobile industry, attracted a high number of developers and set the standard for the industry. Despite success, this market has yet not been the topic of any academic study, a fact that makes this thesis important. Under the assumption that apps can be regarded as a service, traditional service marketing theories have been applied with the research goal to map existing business models, evaluate revenue potential and understand best practices of marketing techniques. A series of qualitative interviews with representatives from the difference business models, backed by secondary data describing the domain shows how the Appstore has evolved over time and which marketing practices that appear successful.
Hur har utvecklingen av andelen pension?rer i befolkningen p?verkat Tysklands arbetskrafts storlek fr?n 2000 till 2022?
Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.
Datorsystem för kvalitetskontroll och temperaturövervakning med värmekamerateknik
The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .

Aktörer och strukturer: en studie av Karlstads stadsbiblioteks framväxt
The aim of this thesis is to examine the underlying causes for the opening of Karlstad Public Library. In doing so a theory based on the actor/structure model within social theory is used. The structures and actors are intertwined and therefore need to be analysed together. To do so the theory poses a series of questions that needs to be answered. The method used is document analysis.
Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?
This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
I linje med styrdokumenten? - en fallstudie i tre läromedel i engelska
This study focuses on an analysis of three text books in English, Prime Time, Second Time, and Third Time, written for Swedish pupils between grade seven and nine. The main focus of the study is to investigate to what extent the books may be considered to follow the steering principles of the Swedish education system. The theoretical backbone of the essay is centred on the construction and maintenance of stereotypes, and is written from a social constructivist point of view. In this context, I also reason around power relations and norms in the Western society ? arguments which I, in the main analysis, apply to the books in question.
Musik, mening- Svagt t?nkande
This work represents a first attempt to articulate my practice as a composer. Through a phenomenological perspective and with the support of the philosophical concept 'Weak Thought', I approach the idea of music as meaning in itself, beyond language.
My exploration of these ideas is developed through three perspectives: partly through analysis of my own work, partly through a brief presentation of the concept of 'Weak Thought', and lastly through a series of subject-specific reflections..
Efterfrågan på beroendeframkallande varor : En studie om hur efterfrågan på snusprodukter har reagerat på prisökningar i Sverige mellan 1999-2009
Denna uppsats behandlar de relativa prisökningar som skett för snusprodukter i Sverige och vill undersöka om dessa har lett till minskad efterfrågan som nationalekonomisk teori föreslår. Utifrån teori och tidigare forskning har en efterfrågemodell konstruerats för att möjliggöra en statistik undersökning.Variablerna som ingår i modellen är inhämtade från Statistiska centralbyråns prisenhet och Swedish Match AB och inkluderar prisuppgifter för varor, försäljningsstatistik och disponibel inkomst under tidsperioden 1999-2009.Resultaten från regressionsanalyser för tidsseriedata visar på att de ökade priserna har haft en negativ inverkan på efterfrågan på snus under den gällande tidsperioden, men att denna effekt varit förhållandevis liten..
