A measurement system for determining radiation efficiency of a small antenna

The paper describes a system for measuring radiation efficiency of a small antenna operating alone or in the presence of objects similar to those as in an actual service. The system applies the direct approach to determining the antenna efficiency by measuring the radiated field over the entire sphere surrounding the tested antenna. In order to overcome problems associated with the conventional measuring equipment, the antenna under test is equipped with a miniature built-in VCO signal generator and supported by a low reflectivity dielectric positioner. The positioner is of sufficient size and strength to hold a human head phantom to investigate changes in radiation characteristics when the antenna operates in the presence of a human operator.

Kvinnor i styrelser : Att lyckas i en mansdominerad värld

Kvinnor har länge varit exkluderade från ledarpositioner, såsom styrelser, men utvecklingen mot en mer jämställd könsfördelning går långsamt framåt. Syftet med uppsatsen är att skapa förståelse för hur kvinnor i styrelser kan bidra till utvecklingen mot en jämnare könsfördelning. Genom att intervjua fem kvinnliga styrelseledamöter har vi fått en inblick i deras upplevelser och erfarenheter av styrelsearbete och könsroller. Kvinnorna i undersökningen har, genom många års styrelsearbete i olika former samt genom gedigna arbetserfarenheter, arbetat sig fram till ledande positioner inom olika branscher och företag. Även om de överlag inte anser sig ha behandlats annorlunda i styrelsen på grund av sitt kön kan vissa av kvinnorna ändå uppleva att de ibland förväntas ansvara för specifika uppgifter just för att de är kvinnor, att de behöver tuffa till sig eller att de måste vara mer pålästa och duktigare än männen. De anser att kvotering kan vara det enda sättet att få jämställda styrelser men understryker att det bör vara kompetensen som avgör vem som får uppdraget. För att lyckas bra som ledamot krävs, enligt respondenterna, en viss baskunskap om ekonomi och ledarskap samt ett visst mått av självsäkerhet och att våga stå för sina åsikter. Kravbilden på styrelsemedlemmar i bolagsstyrelser har ökat under de senaste årtiondena och det krävs att medlemmarna som individer har en hög kompetens och att styrelsen i sin helhet besitter en bred kunskapsbas. Denna utveckling kan ha en positiv effekt på könsfördelningen då det är fler kvinnor än män som har universitetsutbildning och eftersom en mer heterogen grupp ger ett bredare spektrum av kunskaper. Kvinnorna i undersökningen har genom sina positioner bidragit till brytandet av normer och gör det därför lättare för andra kvinnor att följa i deras spår. Det råder ingen brist på kompetenta kvinnor men utmaningen ligger i att kartlägga och synliggöra dessa kvinnor och ge dem samma möjlighet som männen att nå ledande positioner.

Intern kontroll: En fallstudie på Trafikverket

Internal control is something that’s grown more important for enterprises to keep in mind. The community is increasingly affected by the IT-development which demands a bigger degree of security. Enterprises needs to make sure that their systems are up to date and secure enough to keep it safe from unauthorized to take part of sensitive information. Internal control can exist in a major part of the work. If an enterprise have a goal for no harm or serious injury at work, internal control is necessary to reach that goal. The purpose for this essay is to examine how five different departments of Trafikverket practices internal control. How internal control is described. How the guidance from the managements is described and how it reaches the rest of the enterprise. This will lead to a proposal of improvement of the internal control at Trafikverket. We focus our frame of reference on the COSO-model and its five components. The components included in the COSO-model are control environment, risk valuation, control activities, information and communication and monitoring. The essay is a case-study of Trafikverket. We have chosen a qualitative method and interviewed five respondents from the different departments on Trafikverket. The respondents we interviewed works with internal control in their everyday work or have a god insight in the subject. We used a semi structured interview guide with questions based on the COSO framework. The results from our study shows that it exist big variations between how the departments work with internal control. It emerged that there are new guidelines for how the work should be done. This makes it necessary with education to implement the new ways to work. How the departments use the COSO-model varies. Some of them have incorporated the model in their new ways to work others have never heard of it. The conclusion of our study shows that the COSO-model and it´s components contribute to a functioning internal control. Implementing the components is important and the most important feature to good internal control is the corporate management. Education within the enterprise is the most effective way to inform the staff about the model and to implement it.

Regionen och EU? : Uppfattningar och attityder till EU-relaterade frågor i Västsverige

This thesis explores perceptions and preferences on regional action in EU-related frameworks among regional actors in Western Sweden. Building upon the literature on Europeanisation and the Fusion approach, three dimensions of Europeanisation are clarified and explored– download, upload and crossload – and together with a set of five variables that constitute the Micro Fusion Framework; a comprehensive analytical tool is developed. The thesis analyses the intense debate among the members of West Sweden that took place from 2011 to 2013 that focused on how to functionally organise the regional office in Brussels in order to meet future challenges. Surprisingly, the members eventually decided to terminate their cooperation and close the jointly owned office in Brussels in spite of the fact that it has been widely regarded as successful and effective. Diverging perceptions and preferences is understood in terms of three positions on regional action; a download-, upload- and a coherent oriented position. Finally, the thesis presents the empirical findings and discusses in relation to three fusion scenarios, infusion, defusion and clustered fusion. In terms of Micro Fusion Framework, the dynamics shaping why West Sweden was finally regarded as a dysfunctional arena for regional action are explained by a shift of attention and action among regional actors in Western Sweden that led to pressure for further institutional adaptation in order to meet the demand of how ‘to get the best out of the EU’. Further, this redefinition of how to handle EU-affairs within the upload-oriented position was accompanied by positive attitudes towards the potential to bypass the state and thereby pursue regional priorities directly in Brussels given the compound nature of the EU. In contrast, those regional actors that are found to be more download-oriented often question the benefits of uploading activities in practice and advocate close relations to the state. A coherent oriented position recognises the importance of activities related to both of the vertical dimensions of Europeanisation.
