Jämförelse mellan tekniker för att lagra data i webbläsare : Kan webbapplikationer anpassas för att användas offline?
Denna rapport undersöker olika tekniker för att spara data lokalt i webbläsare, föratt möjliggöra att webbapplikationer kan användas i webbläsare närinternetanslutning saknas, och för att minska mängden data som behöver överförasmellan webbserver och webbläsare.Undersökningen genomförs genom att en befintlig webbapplikation först undersöksför att avgöra vilka datamängder som behöver sparas i webbläsare.Sedan jämförs olika teknikers egenskaper och tidsåtgång för att spara data av olikastorlekar.Resultaten från undersökningarna visar att stödet i webbläsare för FileSystem APIoch IndexedDB inte är tillräckligt för att teknikerna ska användas i publikawebbapplikationer, varför HTML5 Application Cache i kombination med WebStorage är det bästa alternativet att använda för att möjliggöra attwebbapplikationer kan användas utan internetanslutning..

Utvärdering av nätverkssäkerheten på J Bil AB
Detta examensarbete är en utvärdering av nätverkssäkerheten hos J BiL AB, både på social och teknisk nivå. Företaget är beroende av säkra Internet-anslutningar för att nå externa tjänster och interna servrar lokaliserade på olika geografiska platser. Företaget har ingen IT-ansvarig som aktivt underhåller och övervakar nätverket, utan konsulterar ett externt dataföretag. Syftet med examensarbetet är att utvärdera säkerheten, upptäcka brister, ge förbättringsförslag och till viss del implementera lösningar. För att undersöka säkerheten har observationer och intervjuer med personalen gjorts och ett flertal attacker mot nätverket har utförts.
Big data : En studie om dess affärsnytta samt dess utmaningar och möjligheter, med fokus på detaljhandeln
Idag skapas och lagras enorma mängder data, samtidigt som endast en liten del av datan analyseras och används. Big data är ett begrepp som cirkulerat i flera år, men på senare år har det fått allt större innebörd. Allt fler företag börjar få upp ögonen för big data, samtidigt som få verkligen vet hur det ska användas. Vissa frågar sig till och med: finns det någon affärsnytta? Med fokus på detaljhandelsbranschen undersöker vi huruvida det finns en affärsnytta med big data, och framförallt vilka utmaningar och möjligheter som finns kopplade till det.

Cykelparkering i stadsmiljö : en redogörelse för cykelparkeringens komponenter
In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.
Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.
Energikloka hus i Järinge - energiteknisk uppföljning
Energy-wise houses in Järinge - technical follow-up The company JM built energy-efficient houses in Tensta in Stockholm. They have built a total of 16 houses divided into two parts of A-houses and B-houses. The buildings are an attempt by JM to minimize energy-use of the buildings without affecting the comfort and living standards. The project aims to examine the data for the 16 houses on the basis of data and produce a report showing how the buildings worked through a technical perspective. JM approximates that the purchased energy will not be higher than 95 kWh/m2 per year.
Informationskrigföring - den nya teknikens hot
The new information society has revolutionised almost the entire world. But the
new technique does not only bring good. That which was before only available on
paper may today only be available on a computer system. This makes it possible
to send data electronically. In the wrong hands that information can become a
threat against the security of an individual, a company or even a nation.
The possibility to protect oneself against attacks from the outside becomes
increasingly difficult.
Webbläsartillägg för inhämtning av data
Speedledger is a company that is working to automate electronic accounting for businesses, organizations and associations.In the current situation bank data is sent from the users internet bank to Speedledger via a virtual printer driver. The driver transforms the web page into a PDF and sends it to a server for interpretation.The problem is that PDF is not created for this sort of data transfer and makes the interpretation of data is very problematic.The goal of the thesis is to study whether there is a possibility to develop a browser add-on that can retrieve information on the customer's banking page and send it on to Speedledgers server for interpretation. My task was to implement a add-on for one of the three major browsers Mozilla Firefox, Google Chrome or Microsoft Internet Explorer, and then study the possibility of implementing it to the other two by reading the documentation.What I concluded was that it is possible to implement for all the three browsers. However, the techniques will differ slightly when developing these add-ons. .
Företags hantering av konsumentdata : Speglar användares elektroniska fotspår förhållningssättet till integritet?
The essay concerns corporation?s usage and consumer?s attitude towards the phenomenon Big Data. The aim is to analyse whether corporation-management and future ambitions concerning consumer data coincide with attitudes and opinions of today's consumer, and how these opinions reflect consumer behaviour online. The essay is limited to focus on how companies use consumer data in order to better understand and improve the efficiency of their marketing. A self-composed analyse-model was created using previous studies concerning Internet-usage in Sweden, previous management analysis of corporations use of Big Data combined with theory of Cognitive Dissonance. A questionnaire was then created with the analyse model as foundation.
Rättssäkerhet i barnavårdsutredningar : BBIC - ett nytt sätt att arbeta i socialtjänsten
AbstractThe Swedish National Board of Health and Welfare has since a year or so started to introduce a new way to work with childcare investigations within the social services. This new concept, BBIC, is meant to put the child?s needs in the first room rather than the grownup?s as it used to be before. This study is about to examine how BBIC affects the legal security of the children within these childcare investigations.BBIC was first developed in England after a massive criticism against the way that the foster home- and institutional care was handled. In Sweden, BBIC was first tested and developed into Swedish conditions in a few project municipalities for about five years but is now being introduced all over the country.
Inkorporering av extern data i en DW-baserad BI-lösning - utvärdering av ett ramverk
För många verksamheters långsiktiga överlevnad, är det av stor vikt att kunna göra korrekta analyser för att därigenom också kunna fatta bra beslut. Till sådana analyser krävs data av olika slag. Sådana data kan komma från källor inom verksamheten (interna), men många gånger kan data från källor utanför verksamheten (externa) också bidra med värdefull omvärldsinformation. Dataunderlaget till analyserna kan med fördel inkorporeras i ett Data Warehouse (DW), vilket ger möjlighet att använda informationen på ett strukturerat sätt inom ramen för någon form av Business Intelligence (BI)-lösning.Processen att inkorporera data från olika källor till ett DW kan vara komplex - i synnerhet då externa datakällor används. Ett ramverk har tidigare tagits fram i syfte att fungera som stöd vid en inkorporering.
