Digital delaktighet i Sverige : Om att inkludera alla i framtidens samhälle
Almost all Swedes today have access to the Internet, if not through the home then via the library or work. Despite this, around 20% of the population stand outside the information society in that they lack in knowledge, assistive usability tools or positive attitude towards technology and its influence on society. The main factors influencing the digital divide in today's society are age, disability and education, while the main reason for staying outside seems to be disinterest.The question about digital inclusion is important as we now stand on the breaking-point between a society where the industry has had a prominent position for private as well as national economy and a digital society where access to the Internet is no longer about prestige, but where significant differences between users' knowledge levels can create a power gap. Gaps in access and use not only reflects already existing socio-economic conditions, but can also maintain and enhance these.It is crucial for the future expansion of Internet usage how today's non-users feel about becoming users. To understand what underlies the motivations not to use computers is one of the keys to get non-users to embrace becoming users.
Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
LNG träningsmanual för M/T Bit Viking
Denna uppsats är gjord på uppdrag av Tarbit Shipping som år 2011 konverterade sin tankbåt M/T Bit Viking från konventionell drift på tjockolja till LNG (Liquefied Natural Gas).Uppdraget som gavs var att upprätta en tränings manual till fartyget då det är ett krav från IMO (International Maritime Organization). Manualen skrevs i 3 st huvuddelar Kategori A, B och C. Kategori A är till för att manskap ombord ska få en kännedom om gasen och säkerhet runt den, Kategori B är skriven till däcksbefäl där det krävs en större kännedom om gasen och Kategori C är till för maskinbefäl. Manualen finns nu ombord på fartyget och på rederi kontoret för utbildning av nypåmönstrad personal och fortlöpande utbildning av ordinarie personal. Manualen är ett resultat på tolkning av IMO´s IGF kod (ANNEX11.
Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :
During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.
The Student Habitat : "a small and interactive community where students can live, interact and socialize."
I?ve chosen a subject that's close to my heart, as a student who has experiences the need of a change in the traditional student living.I've focused my theses on ?nding the key ingredients for improving an individuals time as a student. In a time when students are struggling to ?nd accommodation that ful?lls the need of being close to university, close to social places, adequate size and affordable. This is close to impossible! This is not just a problem in Stockholm but an international dilemma.The heart of my thesis is, how can we create clever ways of student accommodation with emphasis on community and a more sustainable way of living?Only when we start embracing change and by breaking out of our traditional individual living, can we then start to realise and recognise the bene?ts of working, studying and living together.
Läsa ljud : Att formulera en texts auditiva kvaliteter visuellt
In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.
Optimering av prestanda och utnyttjande av flertrådsteknik
The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..
Är miljöbegreppet hållbar utveckling mycket väsen för ingenting
This essay investigates whether there?s logic behind the sanction system regarding the penalty imprisonment in the swedish penal code. The focus is in general on crimes against the person and crimes against the state, but in particular on crimes of serious fiscal offence and crimes of serious assault. The idea with the essay was also to explain the wording purpose behind the punishment ranges in these selected crimes. The essays focus is on the public unawareness on how the punishment ranges is used.
Modernisering av Javabaserade webbapplikationer : Hur kan man på ett kostnadseffektivt sätt modernisera webbapplikationer, utvecklade med gamla Java-tekniker?
The technology used in the development of web-applications is evolving at such rate that it has become more and more important to keep web-applications modern. If an application is based on a technical platform that is not renewed, the platform may over time develop into an obstacle in further development of the application. There may be compatibility issues and some of the code may be unnecessary due to abstraction, and therefore more time consuming to work with. Sometimes the reason may be that an application has been built to run, and is running on an application server that is no longer being maintained. The system can be large and modernization can cost a lot.
Närliten blir stor : ett företag på väg ut på den globala marknaden
This is a study about a company in Norrköping, called Stadium AB, and its first steps into the global market. We have studied how the conditions of the company have changed during their expansion. This study is not written from the viewpoint of business economics, it is rather a study from a cultural and social studies perspective. The study deals with subjects such as the globalization of society, organizational theories and leadership. The empiric material consists of Stadium?s staff magazine Tracks, the company?s swedish homepage on the Internet and an interview with Sussi Calås-Jonsson, Chief of the Department of Information at Stadium AB.
En studie av två multinationella företags uppförandekoder med avseende på internationella normer och standarder
En svårighet för småföretag är hur de anskaffar kapital för att investera. Många småföretag använder leasing som finansieringsalternativ, trots att leasing inte är den billigaste finansieringsformen.Syftet med studien är att undersöka och analysera varför småföretag använder leasing som finansieringsmöjlighet samt hur leasing som finansieringsform har påverkat småföretag när det gäller ekonomisk utveckling. Studien begränsas endast till att se problemet ur leasetagarens perspektiv.I studien har en kvalitativ forskningsmetod använts för att kunna få fram en djupare kunskap om det undersökta ämnet. Urvalet av småföretag har skett genom kontakt i Lidköping och Skövde. I studien har datainsamlingen skett genom semi-strukturerade intervjuer.
?Hon är min bästa tjejkompis? : En narrativanalys av kärlek och genus i Kamratposten
Kamratposten is a swedish magazine aimed at youth aged 8-14. They write about almost everything that concerns youth, all the way from dealing with loneliness to animals and celebrities. This study concentrates at how they write about love. With a qualitiative narrative analysis of the 12 articles that concerns love from the 2013 issues of Kamratposten, I have tried to answer the questions: - What narratives about love are being constructed in Kamratposten 2013?- How do they construct males, females and gender in their articles about love?What I found was that the hetero normativity, or the heterosexual matrix as Judith Butler calls it, was very strong in the articles.
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
Ansvarsfullt inköp - En Mognadsmodell
SammanfattningCorporate Social Responsibility (CSR) är ett arbetsområde som drar mer och mer intresse till sig, inte minst med inköp och leverantörer i fokus. Ett stort antal akademiska artiklar hanterar ämnetCSR och företag utsätts dagligen för situationer som kräver omfattande CSR-aktiviteter. Dessaaktiviteter skall inte enbart neutralisera hot kopplade till CSR utan även skapa positiva effekter för företaget inom detta område. Litteratur och artiklar inom området fokuserar på hur globala företagintegrerar sociala- och miljöfrågor i deras leverantörskedjor, ofta genom en så kalladuppförandekod (Code of Conduct, även kallad CoC), som leverantörer måste följa för att få leverera till företaget. Trots att artiklarna är många inom ämnet, finns det få som diskuterar hurimplementeringen av dessa uppförandekoder och CSR-frågor skall gå till.
