Fossilfria godstransporter : En undersökning av alternativ till diesel som drivmedel för lastbilar

Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.

Digital doggy bag : iPhone applikation som tar med dina mat- och dryckupplevelser

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.

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Den bristfälliga implementeringen av LSS en studie av maktaspekten i mötet mellan socialtjänsten och människor med psykiska funktionshinder

In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..

Nätmobbning Om relationen mellan traditionell mobbning och nätmobbning i grundskolan

This study investigates the relation between cyberbullying and traditional bullying (in school). In previous research it has been argued that one should separate cyberbullying and traditional bullying both in definitional and measurements issues. However, in Swedish school, there are no marked differences between the two forms of bullying, teachers are responsible to prevent them both. The research is based on 3925 students in years 3-9 (1950 girls and 1975 boys) in 19 schools in the Gothenburg region and two from the Stockholm region. The students have taken a digital survey at school, regarding both traditional and cyber bullying.

Minnesallokering och debugverktyg

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

Konstruktion av efterbehandlare

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Den virtuella dejtingvärlden : En studie om användandet av nätdejtingsajter

The purpose of this study has been to investigate the virtual world that people are part of on online dating sites. To do this we have investigated two different research questions, which are the following: What functions do the online dating sites provide? Why and how are the online dating sites being used by their members? In order to gather information about these matters, we have used a qualitative method consisting of participating observation, scrutinizing and single person interviews. Our results indicate that people have different goals with their usage of online dating sites; some are looking for love, a long-term relationship while others are looking for sexual contact. There are many different online dating sites to choose from depending on the users? objective.

Under vilka fo?rutsa?ttningar kan tjänster outsourcade av finansiella bolag undgå merva?rdesskatt? : En studie av praxis med utgångspunkt i SDC-fallet

This paper deals primarily with the developmental potential and use of court -based mediation in Swedish law, and its relation to court-based conciliation and the judicial procedure as means to end a conflict.  In Chapter 42, Section 17 of the Swedish Code of Judicial Procedure, a judge, before the parties have their main hearing, can act as a mediator between the parties to settle the dispute. The judge should, according to the law, always try to make the parties come to an agreement before the main hearing. This obligation can be fulfilled either through the use of court-based conciliation, or court based mediation. Mediation as such is rarely used in Sweden, and one of the goals of this essay is to try to provide a tentative answer to why that might be the case.  The second goal is to try to find a consistent, yet flexible notion, of the concept of ?jurisdiction?, and to provide an explanation for the relation between mediation as an alternative method for dispute resolution and the judicial procedure.                                                                                                                                            .

Simulering av kötider för en alternativ trucklösning vid Holmens kombinat i Iggesund : Simulation of queueing times for an alternative unloading solution at the integrated milll in Iggesund

Dagens låga lagervolymer vid industrierna har inneburit högre krav på transportstyrningen av ankommande virke för att säkerhetsställa en kontinuerlig råvaruförsörjning. Kombinatet i Iggesund, som är en del av Holmen AB, har sett potential att effektivisera sin vedhantering vid det massabruk samt sågverk som utgör kombinatet. Vedhanteringen är idag tydligt separerad mellan massabruk och såg. Studiens syfte var att kvantifiera effekten av ett samarbete med vedhanteringen mellan massabruk och såg samt en förändring i lossningsresurser med avseende på relativa kötider för virkesfordon som ankommer till kombinatet. Med händelsestyrd simulering skapades en modell över kombinatet.

Mohammedkarikatyrerna och skapandet av den Andre : En diskursanalys av den andres dominerande roll och identitet i Sverige

The aim of the paper is to explore the dominating perception of the Other after the conflict regarding the Danish Mohammed caricatures. How Swedish newspapers have portrayed Arabs, which role they have been given in society and what problems they are struggling with is going to be the focus of this thesis.As methodological approach I chose discourse analysis, since it presents a view where language defines and structures our understanding of reality. Through the study of various Swedish newspaper articles, this essay tries to illustrate the implicit yet existent negative image of the Arabs as a group and potential alternative ways of understanding the Other.The perception of Arabs is a product of a necessary imaginary foe, a mirror image of the bad and strange in contrast to the idyllic and safe Swedish nationality. The rhetoric?s of the discourse are therefore constructed between a politics of acknowledgement and a will to culturally dominate the Other.

Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Punktlasttestning av olika bergartstyper i Kiirunavaaras liggvägg

Examensarbetet ingår i den slutliga delen av kandidatutbildningen i naturresursteknik och utgör 15 högskolepoäng. Utbildningen är inriktad mot geologi och det avslutande arbetet ska ha anknytning till ämnet. Under våren 2012 presenterade representanter för LKAB förslaget att basera examensarbetet på att dokumentera hållfastheten hos bergarter från Kiirunavaaras liggvägg med hjälp av punktlasttestning. Tidigare undersökningar av hållfastheten hos bergarterna i Kiirunavaara har främst gjorts genom enaxiella tryckhållfasthetsmätningar. Det finns ett behov av att undersöka hållfastheten hos bergarterna i Kiirunavaara då gruvbrytningen sker djupare ned i jordskorpan och kraven på säkerheten ständigt ökar.
