Mobil kommunikation och högre tillgänglighet vid längre elavbrott : Exemplet stormen Dagmar och 4G-kommunikation inom smarta elnät
To be able to secure a safe and reliable power supply is becoming increasingly important since society depends on services and functions that need continuous power supply. The delivery rate in Swedish power supply is 99.98 % which insists on a high availability. During the past decade several storms has passed Sweden which resulted in large amount of tree felling leading to extended power outages. During these storms many socially critical activities, such as electric utility company Fortum, experienced disruption in mobile communication which affected the crisis management. This paper has investigated Swedish mobile operators? crisis management at Hi3G, Tele2 and TeliaSonera with a case study of the storm Dagmar that hit Sweden during December in 2011.
Product Return Process - Developing a Web-Based Return Form to Improve the Information Flow between an Apparel Company and Its Retailers
Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.
Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..
Lean för lantbruksföretaget : utvärdering av industriellt managementsystem i agrar kontext
The competitiveness and profitability of swedish farm enterprises is frequently discussed in agricultural media. Increased exposure to the surrounding world with greater competitive pressure and considerable price fluctuations in the agricultural markets demand new ways of acting to secure the agricultural sector?s long-term survival and profitability. Structural change and/or diversification leads to increased numbers of stake-holders around the farm enterprise and thereby also the expectations of the farmers ability to lead and coordinate resources. Lean is the name of a management model developed by Toyota, influenced by the lack of resources in Japan during the post WWII period.
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Ergi inom kult och magi : under den skandinaviska järnåldern och äldre medeltiden
Syftet med min undersökning har varit att undersöka receptionen kring det ryska konstkollektivet Pussy Riot. Jag har försökt att finna svar på vad det är för omständigheter som ligger bakom uppmärksamheten som gruppen har fått internationellt och i Sverige. Detta har jag gjort genom att utgå från ett genusperspektiv med en speciell inriktning på feministisk konstteori. Med hjälp av internationella artiklar och svensk dagspress har jag gjort en övergripande analys av receptionen kring Pussy Riot och deras konst. Genom materialet har jag kunnat undersöka olika kontexter som Pussy Riots konst har skapat reception inom.
Mervärdesskattefrihet och avdrag för ingående mervärdesskatt vid omstruktureringar : Mervärdesskattefria andels- och verksamhetsöverlåtelsers gemensamma respektive enskilda förhållande till avdragsrätt för ingående mervärdesskatt på rådgivningstjänster
The first aim of this study is to examine what the differences are between the Classic directive (directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts) and the Revised Classic directive (directive 2014/24/EU of the European Parliament and of the council of 26 February 2014 on public procurement and repealing Directive 2004/18/EC) when it comes to social considerations in public procurement. The second aim is to examine if the revision of the directive has solved the prior existing problems regarding social considerations in public procurement. In this paper a traditional European legal method is used. The examinations show a number of things, including the Revised Classic directive involving codification of case law, references to other sources of law and some clarified rules as well as new provisions. The regulations regarding reserved contracts, technical specifications, and selection criterion are satisfied in the Revised Classic directive.
Jämförelsestudie mellan AP-fondernas Sverigeportföljer och storbankernas Sverigefonder 2002-2006
The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.
