I många nätverk antas det att någon form av fix infrastruktur existerar och att nätverkets olika noder kan använda denna för att kommunicera med varandra. I ett ad hoc-nätverk antar man att det inte finns någon fix infrastruktur och att noderna måste använda varandra för att kunna kommunicera. Ett exempel på ett ad hoc-nätverk kan vara bärbara datorer sammankopplade med infraröda länkar under ett möte. När ad hoc-nätverket är mobilt innebär det att noderna rör sig.I detta arbete har de tre protokollen Epidemic, GeoMean och GeoMove tillsammans med de två rörelsemodellerna Waypoint och den utökade slumpmässiga vandringen implementerats i en nyskriven simulator för denna typ av nätverk.De två Geo-protokollen är nyutvecklade och syftar till att använda geografisk information för att underlätta kommunikationen i denna kategori av nätverk tillsammans med den nya utvidgade slumpmässiga vandringsmodellen..

Detta arbete tar upp och diskuterar det eventuella användandet av representationer i en autonom robot kontrollerad av ett extended sequential neural network (ESCN). Diskussionen utgår från en tidigare distinktion, framförd av bl.a. Bickhard och Terveen (1995), mellan traditionella representationer, som förespråkas av kognitivismen, och interaktiva representationer, som förespråkas av många företrädare för en mer förkroppsligad och situerad syn på kognition. Resultatet i detta arbete visar att det är möjligt, med hänvisning till robotens interna tillstånd, att påstå att roboten inte använder sig av representationer i någon traditionell bemärkelse. Resultatet visar vidare att det är möjligt att hävda att roboten använder sig av interaktiva representationer.

In today s society, services are becoming more and more important. They are however, partly because of their immaterial nature, separated from traditional merchandise, why the marketing and producing of them differs. Quality errors in a service are often difficult to discover before the service is brought to a customer, since the producing and consuming of it often takes place simultaneously. Quality errors in a service process are called service failures or in Swedish tjänstefel. Nevertheless, with an effective service recovery process, dissatisfied customers can be turned into satisfied ones.

Den obemannade  helikoptern Skeldar utvecklas av Saab Aeronautics. Saab är intresserade av hur väl sensorfusion kan användas för navigering av en obemannad helikopter. Med sensorfusion kan tillgängliga sensordata fusioneras. Det är mätningar från accelerometer, gyro, GPS och magnetometer som används av olika Kalmanfilter. Olika sensorfusionsmetoder föreslås, däribland Extended Kalman Filter (EKF) och ett heuristiskt filter för att visa på hur man intuitivt kan göra för att fusionera mätningar jämfört med det modellbaserade sättet som Kalmanfiltret erbjuder.

This study investigated a local aspect of theSwedish elementary school modernization process between the years 1871-1882.Previous studies have been drawn from the school inspectors own reports andshow that the schoolboards housed a negative and resentful attitude towardsreforms and the school inspectors often felt that the parish priests were moreinclined to changes than the schoolboards themselves.  Other research on elementary schoolmodernization has stressed the matching grants as a major cause of developmentand further establishment. In this study, however, a schoolboards own notes inthe form of meeting protocols during an eleven year period as well as a letterby a priest Erik Lundberg, Redogörelseför skolhusfrågan i Tierp dated 6 October 1880 were analyzed to see if theprevious explanation of school modernization, in particular with regard to thereluctance to change by the schoolboards goes to demonstrate and confirm. Theresults of this study have shown that even if the schoolboards do notimmediately follow the school inspectors instructions, it seems not primarilybeen due to resentment. Reforms within the school world are well known forbeing time-consuming but for the current period, as this study concerns andwithin this specific parish there were conflicts of interest which are notshown when only the inspector?s accounts and reports are examined.

Spectacular buildings and categorized districts are becoming more common elements in cities. In many cases, they are the result of city branding, which means choosing a city image and dealing with it like a brand to profile and compete against other cities. This essay study what impact on and roll in urban planning the trend might have. The first part relies on literary studies and describes what has been written about city branding. The globalization, the experience economy, urban management, urbanization and the theory of the creative class are pointed out as driving forces of the popularity and the spread of city branding.

Stora delar av världen genomgår idag en omfattande urbanisering, där allt fler flyttar från land till stad. Samtidigt ges diskussionen om hållbar utveckling mer och mer relevans och utrymme. Som en följd av rådande urbaniseringstrender tycks resonemang kring miljömässig hållbar utveckling ofta beröra hur de urbana strukturerna ska kunna komma att möta framtidens klimatutmaningar, snarare än att alternativa strukturer lyfts fram som möjliga, mer miljövänliga, alternativ. Denna uppsats syftar till att ge en djupare förståelse för vilken betydelse relationen mellan stad och landsbygd har för en miljömässigt hållbar utveckling. Uppsatsen tar sin utgångspunkt i en beskrivning av och diskussion kring miljömässig hållbarhet (och icke-hållbarhet) i staden respektive på landsbygden. Denna beskrivning och diskussion ligger sedan till grund för en analys av huruvida Region Skåne förhåller sig till de miljömässiga fördelar en stärkt relation mellan stad och landsbygd innebär.

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

This project is made to see at which time at the year it?s best to sell an apartment inside the tolls in Stockholm city. The two types of apartments that are compared are one room and four rooms.The comparison is made at the request of Valuegard since they were interested in the result and it?s considered as a interesting comparison.This comparison can be extended to other amounts of rooms in an apartment. But in this project, only two types will be represented.The result can be used both for those who wants to sell and buy an apartment.

Take your phone out from your pocket and look at it. Chances are that a certain California-based company made it; in 2013, it was quite likely. If you flip it over and remove the shell you have added (or look through the protective film), you might also learn that it was assembled in China. Flip it over again and look at the picture of something or someone you find great affection for, protected by yet another thin film. While who made it and who assembled it might vary, and it does not matter from now on, the other parts about protective barriers and personalization might be more accurate.

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

In what French philosopher Gilles Deleuze labelled Control Societies, mechanisms reminiscent of censorship ? that is, restriction of information that administrators of power wish to regulate the spreading of ? are present in the concept of copyright. This kind of censorship has theadvantage of not being scrutinized by public eyes in the way that the work of institutionalized censorship agencies such as the Swedish Statens Biografbyrå was. It is not unlikely that expanded possibilities for punishing anyone who spreads copyrighted material will result in larger and larger areas that may not be accessed, as the avoiding of conflict and repressive actions will emphasize the behaviour to take detours around information that is deemed taboo and therefore suspicious and dangerous.The ACTA trade agreement is one proposed tool for such extended possibilities for punishment. This essay does not however claim that copyright and censorship are the same ? but rather that the institutional execution of power that was previously a matter of state censorship has a lot of similarities with current and prognosticated application of copyright laws by corporations.While claiming to protect the individual, the disciplinary power executed actually aims to protect the one executing it; the purpose of the power structure is to replicate itself..

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

Turkey has recieved recurring criticism on their disrespect of women and their rights and The European Union Commission and CEDAW, the Convention on the Elimination of all forms of Discrimination Against Women, are two examples of critics. However, during the last years Turkey has shown a number of improvments and positive developments. Two flagrant examples of the extended debate of the above mentioned scarcity is within the area of legislation and the large number of womenNGO´s.The aim of my thesis is to investigate which strategies womenorganizations in Turkey are using to affect the political agenda from a genderperspective; do they choose an international or a national strategi? The analysis is based on four womenNGO´s and their efforts of influence and effects on the political agenda and how they experience the link between themselves and the Turkish government. My findings suggest that a national strategy is chosen before an international strategy, but the choice seems to depend on specific goals of the organization and the national climate.

The aim of this study is to examine reading on the MobileReadforums. The term ?to read? is extended to also cover bookcollection and usage of new technology such as mobile readerunits.A catalyst for reading on mobile reader units seem to be the needto always have access to the personal e-book collection. Apartfrom being a source for reading the collection of e-books alsoserves the purpose of extending the members self-esteem.A large portion of the activities on the MobileRead forum isaimed at making new technology comprehensible with the help ofprotocols to determine the usage of that technology. The processof making protocols also seem to be another way for the membersto extend their self-esteem.Traditional libraries are mainly seen as one of many sources for ebooks.Librarians are mostly perceived as being service mindedbut lacking in e-book knowledge.There is also a risk for miscommunication as the library hasdeveloped other protocols that defines an e-book and how itshould be used.This study is a qualitative analysis based on forum posts collectedfrom the MobileRead forum..
