Kommunikation mellan två medium

The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

Implementation av fältbuss ASIC i FPGA

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution..

Al-Qaida - mellan tankeprodukt och reell fiende

The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.

Vem får höras? : En undersökning av lokalpress kring makt och kön i fyra Landsortstidningar

2 (45)AbstractAuthors: Gunnel Forssell Ehrlich & Alexandra WinbergTitle: Gender in local press ? a quantitative study of four local newspapers Level: BA Thesis in Media and Communication StudiesLocation: Linnaeus UniversityLanguage: SwedishNumber of pages: 50The report shows a quantitative study of balance in gender and position of power in the local press. The study aimed to shed light on the distribution of space in the newspaper between men and women, those within power and those without in Swedish local press. The study was conducted with four newspapers, during a month of time with local editorial news material. In our study, we have assumed Lippmann?s and Strömbäck?s theories of pseudo-reality and distribution of gender and position of power in Sahlstrand and Jarlbro.

Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

Mikrosensorer i nätverk

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Smarta elnät i Sverige : Energibranschens förutsättningar och förväntningar

The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.

Personarkiv på Kungliga biblioteket -ordningar, kopplingar och krockar på ett nationalbibliotek

The departure point of this thesis is the context of the institution and the processes surrounding the handling of personal archives at the National Library of Sweden. These processes are examined using Actor Network Theory. Around the personal archive a network is constructed and contained by actors ? the archive itself, the librarian, the conservator, the researcher, organizational structures and others. Within this network choices are made of what is significant.

Regional utvecklingsplanering och grönstruktur : en studie av de gröna kilarna i Stockholms län

The aim of the thesis is to analyze the role of regional development planning concerning a regional perspective of green structure and to reflect on its future role. The target group of the study is foremost practitioners but also students of regional planning and development. Three questions are examined. 1) What view concerning green structure has the regional planning body of Stockholm County Council (RTK) communicated through the years? 2) Has this view contributed to generating a common understanding concerning green structure among the actors in the county? 3) Has this common understanding been referred to by actors in discussions concerning how this green structure should develop? The empirical material consists of documents from rtk, the County Administrative Board, the municipalities of the county, a network of ngo:s, as well as interviews with representatives from the above mentioned organizations.

Risk- och sårbarhetsanalyser för smarta elnät

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

The mobility of employees within the EU, and the Eures Network

En sammanfattning av uppsatsen på maximalt 8000 tecken.This thesis is mainly dealing with the mobility of the employees within the borders of the European Union. Legislative framework from the EU is favourable and the Commission has set as one of it goals to promote the migration. Globalisation trends and contemporary business concepts need people who are mobile on the other hand. But migration numbers are still low within Europe. The purpose of this thesis is to find out how much the legal uncertainties, and the different culture mentality in the workplace of another country act as barriers in the minds of the people who wish to work abroad.

Identitetspresentation på Instagram : En studie i användares upplevelser och attityder till sin identitetspresentation på Instagram

In recent years, the internet has exploded of images. Not at least in the popular photo-sharing network Instagram as one of the fastest growing social network for the moment. Millions of people around the world share pictures and expose themself for friends and family. We were therefore interested in which experiences and attitudes users have towards their identities in relation to their self-image and self-presentation on Instagram. Furthermore, whether they in general have a primary interest in using Instagram as a tool to experiment with images to present their identity on Instagram, in which way they approach their Instagram follower?s expectations on how they present themselves on Instagram and if they are aware of any strategies in their self-presentation on Instagram.The result of this study is the fact that our respondents thinks that they do not intend to have a primary interest in experimenting with images on Instagram to present their identitiy, it is rather something that comes naturally in how they present themselves on Instagram.
