Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry
The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.
Militärtekniskt perspektiv på AUV
Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
Elektroniska tidskrifter - var, när, hur och i så fall varför?
An increasing number of scholarly publishers are beginning to make their journals available electronically. At the same time there is a growing amount of exclusively electronic journals freely accessible on the Internet. These are facts that librarians have to take into consideration.This master's thesis aims to describe the electronic journal and its role in Swedish academic libraries. In a review of current literature about electronic journals, the authors discuss their strengths and weaknesses, and their impact on scholars, publishers and libraries. To investigate the situation in Sweden, a questionnaire was sent out to 43 academic libraries.Questions were raised about the selection and acquisition of electronic journals, access, technology and economy.The results show that almost half of the 35 responding libraries offer electronic journals to their users.

Eldens arkitektur : En studie av de medeltida varmluftsugnarna och deras betydelse
AbstractThis thesis examines and discusses a sample of the medieval hypocausts (stone-heating ovens) in the Baltic area. The medieval construction is thoroughly explained as well as the antique hypocaust in order to establish a base for the following discussion. The medieval hypocaust has been almost forgotten for a long period of time. The last time someone dealt with this category of finds were in the 1960?s by Swedish archaeologist Iwar Andersson and in the 1970?s by Danish archaeologist Johannes Hertz.
Ytbearbetning av ersättningssten för kulturhistoriska byggnader
The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
En fjärran framtid : införande av digital teknik i gruvor
Traditionally, mining has been performed mechanically with implementation ofyesterdays (and older) data. Several mining companies have started to useautonomous technology and robotics in the production areas although the harshmining environments make it unsuitable for today's electronic equipment. Despite allthe obstacles along the way of digitization, there seems to be no end in sight as thisdevelopment continues. This thesis focuses on what the mining industry is aiming forand why the mining companies are interested in these technologies. The actors of themining industry can be found to have a vision for the future mine, a production with ahigher degree of digitization and resemblances to a factory.

Undersökning av mental arbetsbelastning under instrumentflygövningar
En människa har en viss mängd kapacitet för att utföra uppgifter. Om uppgifterna blir för svåra eller för många, det vill säga om den mentala arbetsbelastningen blir för hög, går det inte längre att klara av alla uppgifter och prioritering av de viktigaste uppgifterna blir nödvändigt. Piloter behöver ofta ta in och bearbeta en stor mängd information under instrumentflygning. Ofta måste en del av uppgifterna utföras samtidigt och på begränsad tid. Syftet med examensarbetet är att, med hjälp av en subjektiv mätmetod undersöka vilka moment under instrumentflygövningar som medför störst respektive minst mental arbetsbelastning.

Etik och censur inom internetfiltrering ? En forskningsöversikt
This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.
Affärssystem ? attityder vid införandet av ny teknik ? Vad måste man tänka på vid ett systembyte
ERP system is the information technology that has had the biggest impact in companies? development and way of working in today?s world. ERP system is divided in several applications with a modular software design that allow people in every department in a company to store and retrieve information accurately and in real-time. This master thesis investigates attitudes toward ERP systems among business organisations and ERP suppliers with the overall purpose of analysing to which extent a new ERP system will bring change in the business process. The purpose of this thesis is to make a survey of attitudes toward ERP systems among business organisations and ERP suppliers.
MIMO kanalmodeler
The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.
