Enterprise Mobility: Effekter på den individuella arbetaren. En fallstudie av en mobil affärsapplikation hos ett teknikföretag i Västsverige

Using mobile technology to make ends meet is currently a reality for many people. More and more peopleare working while travelling or work from home. Most knowledge workers are equipped with laptopsand smart phones. To find out how individuals are affected by having the ability to stay continuouslyconnected and work with mobile business applications, we have conducted a case study and in closecooperation with a company have created a prototype of such a mobile business application. Fourindividuals have tested our application and were then interviewed.

Får vi se ? datakvalité. Effektivisering av supportprocessen hos Tunga Maskiner AB

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

Är det någon skillnad? : En kvalitativ undersökning om bibliotekariers uppfattningar om den användarstyrda förvärvsmodellen Patron Driven Acquisition.

This thesis is about new technology in academic libraries in the form of Patron Driven Acquisition. As libraries take part in the digital era, a new model of patron driven acquisition has emerged. This model gives users more influence over the libraries electronic book collection. The collection development model changes libraries traditional role in the collection development process, from collecting for the future to the present.The purpose of this thesis is to gain knowledge of what acquisition librarians think about the effects of PDA on the collection, the acquisitions role and the cost structure. The theoretical framework relies on Christensen?s theory about disruptive technology and was used to interpret outcomes of new technology in libraries and its staff.Five librarians from four different Swedish university libraries were interviewed using a qualitative semi-structured method to carry out the investigative part of this thesis.

Direktdemokrati och representativ demokrati : En jämförande analys mellan två demokratimodeller och en definierad idealtyp

The essay?s main focus has been to investigate and analyze the political actions behind the 2015?s grade compromise; an agreement to introduce grades from the fourth year in primary school. Through a game-theory analysis, mainly based in Leif Lewin?s and Jörgen Herman's research on rationality in politics, this study examined the grade debate  during a fifteen year period. The primary task has thereby been to explain the grade compromise through game-theory.

En diktaturs väg in i Informationssamhället Kina och World Summit on the Information Society

This masters thesis investigates the relation between China and the Information Society as it is manifested in the UN conference the World Summit on the Information Society WSIS. The first phase of this two-phase conference took place in Geneva 10-12 December 2003, with two documents, Declaration of principles DP and Plan of action PA, as main results. The information policy is central to an authoritarian rule in its efforts to keep control over the national identity. The thesis investigates the impact that the information revolution and Internet might have on the Chinese national identity through the acceptance of DP and PA in various aspects. With the use of the information science theories by Manuel Castells and Frank Webster, the vision of WSIS was compared with the Chinese information policy.

Applikationsintegrering - en analys av metoder och teknik

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications. There is a range of different middleware products offered today on the market.

Commercialisation of inventions from a legal and business perspective

This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.

Hallmöbel för förskolor

I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.

Framtidens Hus

The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Den Digitala teknikens påverkan på resebranschen och dess marknadsföring

The intention of this essay has been to investigate how the new digital technology has affected the tourism industry and marketing, as well as how travel agents and tour operators adapt to this. We also aimed to get a broader view of how the future might look like when it comes to marketing and virtual service landscapes. We decided to base our research according to these following four questions:? What affect travel agents? way of adoption to the technical development?? What purposes do the travel agents have for building up their virtual service landscape?? How much does the travel agents emphasize on digital marketing?? What can travel agents do to better adapt to the technological development in the future?We have chosen to use a qualitative research for this essay. The reason for choosing a qualitative research was to gain a wider understanding that would represent a big part of the changes of technology development.

Anslutning av vindkraft till ett svagt nät i Tidaholm

Vindkraftverk ansluts idag i snabb takt till elnät runt om i världen. Elnäten är ofta inte tillräckligt dimensionerade på platser där vindkraftutbyggnad är lämplig vilket leder till ett behov av nätförstärkning. Förstärkning sker konventionellt genom att övergå till en högre spänning, något som kan vara förenat med stora kostnader och ledtider. Bland annat därför har en filosofi med beteckningen smarta elnät uppstått, som handlar om hur elnätsystemet ska se ut när det är mer anpassat till de nya energikällornas karaktär och samtidigt medför ett mer effektivt totalutnyttjande. För vindkraftverk kan det då handla om att i högre grad än idag reglera produktionen och understödja nätet, t.ex.

Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

Solenergi på Nya Karolinska Solna

In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors  to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.

Hantering av QoS i Distribuerade MPEG-videosystem

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.
