The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.
Lagafors CPU : Chemical Production Unit
This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .
Att göra tillit : Hur tillit skapas i interaktionen mellan människor
The purpose of this essay is to examine the origin of generalized trust. We compare existing theories on trust to determine what approach is more fruitful in explaining the prevalence, or absence, of trust. Our conviction is that trust should be viewed as an interaction, rather than a disposition or a rational choice. The sample is based on the countries of the OECD. In total, five different hypotheses are tested: i) that generalized trust is created by equal distribution of income, ii) that generalized trust is created through monitoring of the state, iii) that generalized trust is created through rule by law; iv) that generalized trust is created when the welfare apparatus is guided by principles of universalism; or iv) that generalized trust is created when the state integrates trust networks.
Optimering av CellularIP-nätverk
Cellular IP är ett nytt nätverksprotokoll på ingång som är tänkt att lösa prestandaproblemen i Mobile IP. Influenser har tagits från hur mobiltelefonnäten är uppbyggda för att lösa problemen med förflyttning mellan basstationer på ett smidigt sätt. Detta examensarbete syftade till att optimera routingfunktionen i ett Cellular IP nätverk och integrera det med Mobile IP. I uppgiften ingick också att installera och om nödvändigt modifiera befintlig kod för Linux Mandrake. Rapporten innehåller dokumentation för installation och konfiguration av protokollet samt all nödvändig programvara.
Maktstrukturer i svenskt näringsliv: En social nätverkstudie av delade styrelseledamöter i Sverige 1985 och 2005
This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.
WLAN : Oskyddad och okontrollerad datakommunikation
This master?s thesis investigates the technology and security awareness associated with wireless networks (WLAN). It has been stated by the media and theories that many wireless networks are unprotected. This has sparked an interest to investigate the phenomenon in the Jonkoping region. The study is based on the following research questions:- What security weaknesses are present with the WLAN-technology and how can these be avoided?- How does the wireless infrastructure in the Jonkoping region look like?- Why do companies implement the WLAN-technology?- Are the companies aware of the risks involved with WLAN?We conducted this study in three steps; the first step was to hack a wireless network in a controlled environment in order to investigate the weaknesses of the commonly used security measures.
Integration mellan informationssystemen & mobila tjänster - Design, utveckling & utvärdering av en prototyp
The company Pilotfish has developed the system MIVEO which is used by car-sharing to wirelessly monitor, book or otherwise manage a fleet of cars. In a car pool the system has three different types of users with varying degrees of eligibility. These are end users, administrative and service personnel. We have chosen to focus on opportunities to streamline the administrator and service personnel work with a mobile service, as these users of MIVEO often are movable and mobile. From this position we have in the study attempted to answer the following question: How can mobile services used to streamline administrative tasks? This study is about developing a mobile application that will contain the same features as the existing system, but must be mobile suit.
Intranät för personliga assistenter : En studie av förutsättningar för effektiv informationshantering i vardagspraktik med stöd av IT
While designing an intranet for people with mobile work there are things you have to consider. This thesis is aim to bring understanding to the difficulties involved in these kinds of situations. Our focus is to develop ideas that motivate the assistants to use the intranet. We have looked into the profession of personal assistants and wish to highlight their problems to access the intranet. And we will as well demonstrate their needs for communication.
Strömmande video i trådlösa mesh nätverk : Streaming video in wireless mesh networks
This document?s content is the final report of the master´s dissertation Magnus Hällström did during springtime of year 2013. The dissertation?s subject is 802.11s wireless mesh networks with streaming video as a focus point. During the dissertation a wireless mesh network was set up with different attached cameras for streaming video. A sun panel solution was also tested with the goal of creating a package with a self-configuring network node streaming video, powered by nothing but solar energy. .
En Mobil Jukebox : Undersökning av Intresset För en Innovationsprodukt
The mobile jukebox is an idea for a new kind of smartphone application that would allow users to dictate the music playing at various establishments. The mobile nature of the innovation allows for the possibility of a more ubiquitous service. Conducting a quantitative as well a qualitative study, the authors have found significant interest in this innovation service among potential users and potential distributors of the service. Furthermore, it is shown what aspects are important for decision makers to make a decision on whether to integrate the service into the operation of potential distributors of the service. .
"Att bygga broar över murar" : en studie av ett kvinnligt ekumeniskt nätverk

Säkerheten i trådlösa nätverk
The number of wireless networks has increased rapidly among both home users and companies in just a few years. That has brought a lot of good things with it, for example the possibility to connect wireless equipment to the network or Internet from an arbitrary position within range of the accesspoint. But since the transmissions take place through the air some new security risks appear. It?s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network.
