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.
MoPho -enkla lösningar för SMS och MMS
Our project is divided into two parts, one production and written report. The
main focus was the production part, were we used PHP to create simple solution
for handling SMS and MMS with direct communication with the mobile operator
server. We communicate with sockets and can handle CIMD2 and MM7 protocol. To
get our components easy to use we have created two classes to handle SMS and
MMS. To demonstrate our technical platform we created a website were you can
create an account.

Shareholder value - The American way and the Swedish game to play? : En studie om ideologisk förändring i svensk bolagsstyrning
Shareholder value has its origin in the American corporate governance system and has been the subject of great debate over the last few decades. The proponents claim that it creates economic efficiency while the critics argue that maximization of shareholder value jeopardizes the long term survival of companies. However, the debate in Sweden already seems to have forgotten the question of how embedded the ideology really is and what´s leading its way. This study show that shareholder value has developed and been established in Swedish companies between 1995 and 2005. The study has found evidence that suggests that the development can primarily be linked to board networks and international exposure.
Styrmekanismers funktion i relationsbyggande: En studie av ett relationsnätverk i verkstadsindustrin
The aim of this study has been to examine the role of control mechanisms when it comes to building relationships in a small business network. In order to reach this goal, we have performed a case study of a Swedish supplier of machines to the engineering industry, which acts as the exclusive representative of a foreign manufacturer on the Swedish market. Main results: A number of control mechanisms, both formal and informal, could be identified in the network. Their specific use, as well as relative importance differ between different actors in the network. In general, the importance of formal control mechanisms decreases as the relationship evolves over time and the importance of informal ones, mainly trust, increases in a corresponding manner..
En studie inom upphandling av GPD
The Swedish State Road Administration has since 1992 procured operations and maintenance of state roads on the open market. The procurement has been termed ?Grundpaket Drift?, GPD, and comprises mostly operational measures for road networks.The clients of GPD, SRA regions, have gradually changed the original documentation in order to adapt it to local conditions. This process has gradually led to that some parts of the documentation are creating problems for contractors interested in procuring jobs.This thesis tries to analyze GPD and clarify the differences that may be essential to the procurement process and to facilitate future joint working projects and processing descriptions..
Trådlöst nätverk : En förstudie vid Campus Norrköping
Syftet med denna rapport är att göra en förstudie vid campus Norrköping rörande trådlöst nätverk. Det finns många olika standarder och tekniker. Vi har valt att rikta in oss på 802.11b då det är den som används mest. Trådlösa nätverk är ett bra komplement till vanliga kabelburna nätverk då det är flexibelt, relativt billigt och lätt att installera. Användningsområden för denna typ av nätverk är bland annat företag, hemmamiljö och allmänna platser såsom hotell och flygplatser, där människor kan förvandla improduktiv väntetid till effektiv arbetstid.
Identitetsskapande viamarknadsföring : En kvalitativ undersökning om hur frilansareväljer att marknadsföra sig själv samt sin karriärmed hjälp av sociala medier
There are those who currently use social networks as a marketing tool that creates the standards that exist. There is no given standard, there are no absolute facts that exist through all time. A constant change is happening and therefore forcing everyone involved to adapt and make the changes needed to be current. What is relevant to consider in this study are the different roles a freelancer creates on the various channels of social media. Based on the results of the interviews that have been conducted the informants create different identities at different forums they reside on.

Entreprenörskap på landsbygden : 6 små livsmedelsförädlande företag i Mälardalen
For a long time, economic activity has decreased and shows a downward trend in the food sector. To break this requires efforts to strengthen corporate position with the ability to meet market challenges.
In the small producers is a great potential for them to be able to increase its profitability thanks to its ability to offer added value in the product. But to achieve this requires not only a willingness and creativity out of the ordinary but also factors that lead us into this report, current issues. The issues are related to marketing, brand building and the importance of developing a stable network.
The study aims to investigate how small businesses operate in rural areas are experiencing the possibilities of support from various networks and organizations and that, from a business perspective, and also see which areas that they need more support in to achieve a growing business. The work has been followed by an inductive method, when we initially could not say anything about the empirical results.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar
A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.
Analys av mätdata från nätstationer
Fortum has in a pilot project installed metering equipment with wireless communication in secondary substations in Stockholm. So far, the collected data are used only in specific projects.This master thesis was carried out at Fortum Distribution AB in Stockholm during 2013. The purpose of this study is to simplify and enhance the use of data in for example network planning process, by giving suggestions on how data can be managed and giving examples of analyzes that collected data can be used for.The electricity meter which Fortum has installed is a EDMI-Mk10A which is set to measure max/average/min values with a one hour time resolution of the following parameters: voltage (per phase), current (per phase) andactive power and active and reactive energy.In order to analyze the collected data an analysis tool is required. During this thesis two customized tools in Microsoft Excel have been developed, one for sorting data and one for analyzing.One aim of the thesis is to show examples of what collected measurement data can be used for. This work shows an example of analysis of active power, power factor, voltage, occurrence of interrupts and the relationship between outdoor temperature and power.This master thesis has among others resulted in the following advice: Expand the number of secondary substations with measuring equipment.
