Mail Exchange Protocol (MEP): Ett utkast till nytt protokoll för elektronisk post
SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.
Att färdas i symbios : ett gång -och cykelstråk anpassat efter trafikanternas rörelsemönster och behov
The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..
Automatiserad Verifiering av Grafiska Ritare och Tranformationsutvinning
En grafisk ritare i flygande system måste under dess utveckling verifieras för
att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara
identiska mot referensbilder genererade av en fungerande ritare så ställer det
krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att
automatisera den processen är i högsta grad intressant för att minska
kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan
uppstå, däribland ett sätt att utvinna eventuell transformation mellan två
bilder..
Artefakter i utveckling - Om designartefakters betydelse i en utvecklingsprocess
Genom att föra samman människor med olika bakgrund och utbildning kan
åtskilliga idéer skapas, nya metoder utvecklas och mer kreativa och originella
designlösningar produceras. Baksidan är, att ju fler olika människor med olika
bakgrund som är involverade i ett projekt desto svårare blir det att
kommunicera inom gruppen av olika individer och svårare att komma vidare i en
design- och utvecklingsprocess. Vi har under våren deltagit som en del i ett
större programvaruutvecklingsprojekt och skapat och använt oss av flera olika
designartefakter som medel för att främja samarbete, kommunikation och
designarbetet av den produkt vi utvecklade. I denna uppsats beskriver vi hur
dessa designartefakter har kommit till, förändrats och hur de har påverkat oss
och vårt designarbete. Syftet med uppsatsen är att visa på vilket sätt man kan
integrera metoder från olika discipliner i ett programvaruutvecklingsprojekt
och framförallt hur arbetet med, och kring designartefakter spelar en viktig
roll i utvecklingen av en produkt..
Dynamisk Scrapeapplikation
Denna rapport beskriver examensarbetet vi gjort för LBS Science Park AB. Anledningen till att vi gjort just denna applikation var att LBS Science Park såg ett problem i den Internetbaserade hästannonsmarknaden. Det fanns ingen ledande annonssida, utan användare som skulle sälja eller köpa hästar fick använda sig av flera mindre sidor. Vår uppgift blev att undersöka marknaden och att skapa en applikation som samlar annonser från flera hemsidor på vår applikation. Rapporten är indelad i tre huvuddelar, som belyser de juridiska, de tekniska och de innehållsmässiga frågorna.
Rysslands politiska utveckling : En fallstudie över svensk säkerhetspolitik
The Swedish security policy has changed from stressing neutrality to embrace co-operation within the EU and other organisations. New threats like terrorism, boarder-crossing criminality and natural disasters require new ways to deal with this type of problems to protect the society. Since the beginning of 21st century the high Russian economic growth has made it possible for the country to play an increasingly role as a superpower on the international political stage. In the same time the democratic development has been replaced by an autocratic rule which has obstructed the Russian- European relations. From a Swedish security policy view the Russian political development is of importance and the picture of Russian as a threat has changed from 1996 to 2008/09.
Digitaliserade möjligheter för skolan : En studie av två spels pedagogiska potential för historieundervisning i grundskolan
This essay examines computer and video games and their capacity of being useful in teaching sessions. Focus is being put at a possible pedagogical potential and how it is being expressed in games mechanics. To get answers on these subjects? studies by Professor James Paul Gee and Jesse Schell is used together in creating a model for analysis. With this model together with a narrative analysis this essay hopes to give clarifications on if a pedagogical potential is present and if so, how it is being expressed.Studies in this paper shows that a pedagogical potential is overall present in used material.
Industriellt byggande – en nulägesrapport
Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.
En digital kärlekshistoria
Kandidatarbetets syfte är att undersöka mötet mellan människa och medium genom
att undersöka hur människor relaterar till och tolkar mötet med ett medium.
Undersökningen tar sin utgångspunkt i flera tänkbara kunskapsfält, bland annat
posthumanism, transhumanism, tolkningsvetenskap. Dessa kunskapsfält prövas
sedan i en gestaltning för att avgöra om kunskapen är relevant i förhållande
till vårt ärende..

Kravanalys och arkitekturell design av en budgetplaneringsapplikation
This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University..
