Together Together

Mobiltelefonen är ständigt närvarande i vår vardag. Den är ett kraftfullt verktyg som hjälper oss med allt från att surfa på nätet till att kolla när bussen går eller att betala räkningarna. Den har också gjort att vi kan dela med oss av våra liv och hålla kontakten med våra nära och kära var vi än befinner oss. Kort sagt har den ändrat hur vi beter oss i de flesta situationer. Men alla dessa ändringar är kanske inte lika positiva.

Flygets framtid : Från problem till möjligheter

The purpose of this essay is to investigate the airline industry and its part in the mobile community. Further on, to investigate the factors that throughout history are having an impact on the airline industry and have lead to the condition of today. Through this information we are outlining the future of the airline industry.This essay has been written in a qualitative approach.

AbstractStudents at Mälardalen University have long performed their lab on a small turbojet engine in the course Aircraft Engine Technology. Since 2011, the engine has been dysfunctional. This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.

Värdeskapande i nätverk

The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.

Analys av ljudspektroskopisignaler med artificiella neurala eller bayesiska nätverk

Vid analys av fluider med akustisk spektroskopi finns ett behov av att finna multivariata metoder för att utifrån akustiska spektra prediktera storheter såsom viskositet och densitet. Användning av artificiella neurala nätverk och bayesiska nätverk för detta syfte utreds genom teoretiska och praktiska undersökningar. Förbehandling och uppdelning av data samt en handfull linjära och olinjära multivariata analysmetoder beskrivs och implementeras. Prediktionsfelen för de olika metoderna jämförs och PLS (Partial Least Squares) framstår som den starkaste kandidaten för att prediktera de sökta storheterna..

Hur säkerställs effekten av marknadsföring när den outsourcas?

Outsourcing is today a common phenomenon among businesses in most industries. The term outsourcing means transferring the responsibility of performing a certain function to an external supplier. There are usually certain methods to investigate the effects and the outcome of a function that is performed by the company itself. When this function is performed by an external party, the complexity of the function will increase.This leads us to our purpose: Based on different theories clarify how a company ensures a desired effect out of marketing when this function is outsourced to a certain retail- and advertising agency.In this essay we have defined us to study one of Sweden´s leading mobile operators who have outsourced their sales management to a retail- and advertising agency. To get an additional point of view, we have included one of the mobile operator´s intermediates, which is a selling agent whose sales function is led by the retail- and advertising agency..

Faktorer som påverkar mobilbanksanvändningen

Many companies today are investing in various computer-based tools to support their planning, decision making or communication processes. However, end users are often reluctant to accept the available information systems, which mean that these investments are extremely risky. Understanding why users choose to accept or reject an information system has proved to be one of the most challenging problems in this research area. Previous studies have focused on users' beliefs and attitudes regarding use intentions, but the results have, however, been both mixed and incomplete. In this study, I have used the Swedish youth? s use intention of mobile banking and a quantitative study was performed based on five different hypotheses derived from previous studies.

Rekommendationer för införande av public key infrastructure

The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

Hur biodiversitet på ekosystemnivå skiljer sig mellan olika habitat

Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

Säkerhetsstandard för ett mjukvarubaserat säkerhetselement

Researchers today anticipate that in the near future, the majority of the owners of a smartphone will use it as a wallet, i.e. for contactless payment. The technology that enables contactless payment today is ?Near Field Communication? (NFC), which is increasingly embedded in smartphones. Applications like mobile payment between a phone and a terminal use NFC.

Utveckling av mobilapplikation

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.
