Hur blir politiska skapelser virala succéer? : En komparativ argumentationsanalys.
Since the beginning of the 1990s, Swedish society has gone through a great change. Firstly with the personal computer and then with the internet moving in to everyday life, a new arena for interaction with society evolved. Work, education, doing bank errands and reading or discussing the news, just to name a few, now all take place in the virtual world online. Not to mention social media sites such as twitter, instagram or facebook, the last of which has over half of the Swedish population represented as members. Companies, corporations, interest groups, political parties and politicians must be aware of the massive impact that a post spread through social media can have. This thesis will, with the text analyzing tool, argumentation analysis, and on the theoretical platform of political communications theory, analyze three of the most viral Swedish political posts spread over 120 000 times each, to see if there are any combined qualities that point to the fact that there is a formula for getting a post to become a viral success on social media. The main result showed that of the three posts analyzed, all were built up around a factual thesis, argued for with foremost example arguments, not only appealing to the logical branch of argumentation but also to the ethical, and that they tended to be of high relevance and sustainability. The conclusion must therefore be that these are all qualities that tend to be of relevance for making a political post on social media into a viral success..
Design, konstruktion och test av LED-spektrometer
A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

This report presents a method for modelling a computer system from a security perspective. The questions that are going to be treated are:? What defines a secure system and how does the company relate to these factors?? What are the threats today based on hardware/software, human factors and company routines/policies?? What measures should be taken for the organisation to reach a higher level of security for their systems?? How do we develop a method for classification of security and what components should it contain?? What changes are reasonable and necessary with the respect to the company?s resources?The report has been done through interviews and analysis of existing systems on Fla?kt Woods AB. From analysis of material, the aspects judged relevant to the subject and to the company?s needs, have been compiled to a document.
Mobile Ajax
This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.
Vägen till Bel Canto : Om min omskolning till Chiaroscuro
I am a practising classical soprano. After more than 20 years of professional singing, I re-trained my voice according to principles of the old Italian school of singing. In this essay, I examine the origins and priciples of bel canto, with special focus on appoggio and chiaroscuro, two key ingredients in the bel cantao tradition. I explore the relationship between science and the craft of singing, and what modern voice science has to say about the efficiency and health aspects of this technique, I also describe the profound effect it has had on me as an artist..
?Naturvetenskap finns ju överallt? : En kvalitativ studie av hur förskollärare på småbarnsavdelningar på Reggio Emilia inspirerade förskolor ser på arbetet med naturvetenskap
The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.
Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer
This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.
Användbarheten på högskolornas och universitetens hemsidor ur studenternas perspektiv.
Problemområde: En del av de högskolor och universitet som har hemsidor har inte
lagt så stor vikt på användbarhet då deras funktionalitet brister. Det är svårt
för deras studenter att på ett så enkelt sätt som möjligt nå den information de
behöver.
Hypotes: ?Användbarheten på högskolornas- och universitetens hemsidor kan
förbättras med hjälp av att krav ställs från studenterna.?
Genomförandet: För att undersöka hypotesen har tre undersökningar gjorts. Den
första var en granskning av de utvalda högskolornas och universitetens hemsidor
av författarna. Undersökning nummer två gjordes med hjälp av enkäter som
studenter vid de utvalda högskolorna och universiteten fick svara på.
Genus och vetenskaplig kommunikation: en bibliometrisk studie av amerikansk biblioteksforskning
The purpose of this paper is to examine how the relationship between the socially constructed genders is manifested in American library science. To visualize gender, bibliometric analyses of peer reviewed articles published in three core journals of library science between 1980 and 2000 inclusive, are performed. The three journals are: College and Research Libraries, Journal of Academic Librarianship and Library Quarterly. Questions: 1. Does gender affect the publishing process regarding the distribution of female and male authors? 2.
Övervakningssystem för båtelektronik
Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.
Hur företag och organisationer kan attrahera innovationsmöjligheter : Ett uppdrag från Munktell Science Park
Syftet med detta examensarbete var att ta fram en modell för att attrahera innovationsmöjligheter till Munktell Science Park i Eskilstuna. Detta gjorde författarna genom att från befintliga teorier deducera fram en hypotetisk modell. Modellen används inte för att skapa innovationer utan för att hitta komplexa problem. Det är lösningarna på de komplexa problemen som i sin tur kan vara innovationerna. Därför har vi kallat de komplexa problemen för innovationsmöjligheter. .
Folkbibliotekens webbplatsers grafiska användargränssnitt Kvalitativa intervjuer med webbansvariga
The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.
Chinese Remainder Theorem
Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.
Privacy Policy - Att skapa förtroende för en uppkopplad värld
Förtroende har sitt ursprung i trygghet och säkerhet. För att lämna ifrån sig
personlig information krävs att man känner förtroende och således även trygghet
och säkerhet. Tillgång till personlig information är en viktig konkurrensfördel
för ett företag. Samtidigt utgör den personliga informationen ett problem
eftersom många kunder känner en oro att lämna ifrån sig denna. Oron beror på
osäkerhet om vad som kan hända med den information man lämnar, denna oro kan i
sin tur leda till brist på förtroende.
