Rättssäkerhet och anstånd med betalning av skatt : En analys av 17 kap. 2 § p. 2-3 Skattebetalningslagen ur ett rättssäkerhetsperspektiv
The aim of this thesis is to investigate whether legal rights are upheld when wording and applying the postponement of payment of tax regulations of chapter 17 section 2 p. 2-3 of the payment of Tax Act. We also investigate how the wording of the regulations relate to the requirement of legal security.It has been questioned if the regulations concerning postponement of payment of tax are compatible with the requirement of legal security. Of course does not a taxpayer want to pay tax that he or she consider incorrect, and that has not been under trial by an impartial authority. If the request for postponement of payment of tax is rejected, the consequences for the taxpayer can lead to huge financial losses.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Det implicita avkastningskravet på Stockholmsbörsen En jämförande empirisk studie med avseende på antalet börsintroduktioner för 1999 och 2012
This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..
Automatisk plastlisthanterare
Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.

Syftet med detta examensarbete var att ta reda på de för och nackdelar som har upplevts av användare som har arbetat med Use Case i samband med kravhantering.
Barn av vår tid : Ett inredningskoncept för ett ungdomscenter
In the project Barn av vår tid (Children of our time), I have worked with Fryshuset in Malmo and created an interior concept which is designed to express Fryshusets identity, support and encourage its activities and to create a functional environment for young people as well as staff. The purpose of this concept is to help teenagers to feel involved, important and safe. Floor plan, materials and furniture is carefully adapted to support the activities of Fryshuset and to give young people a feeling of coming home. They are also of course chosen with care for the environment. I have studied interior branding, how the rooms can give a sense of security and homely atmosphere and how young people can actively participate in the design of the premises..
Free Valve Technology : ? Utveckling av ett styrsystem för ett elektronisk styrt pneumatisk-hydraulisk ventilsystem på en förbränningsmotor
Detta examensarbete är utfört på uppdrag från AVL Södertälje Powertrain Engineering AB.Målet med arbetet har varit att utveckla ett styrsystem för ett elektroniskt styrt pneumatiskhydraulisktventilsystem på en encylindrig förbränningsmotor i en testcell. AVL är enoberoende firma som utvecklar drivlinor med förbränningsmotorer samt instrumenterings- ochtestsystem. Ventilsystemet, med ett fungerande styrsystem, ska användas i AVLs utvecklingsochforskningsarbete på förbränningsmotorer.Ventilsystemet,Free Valve Technology, är utvecklat av Cargine Engineering AB och består avelektroniskt styrda pneumatisk-hydrauliska aktivatorer som opererar en motorventil individuellt.Aktivatorernas styrsystem har utvecklats helt iSimulink och implementerats som en integreraddel i det av AVL utvecklade motorstyrsystemet Raptor. Hårdvaran och plattformen är ett rapidprototyping system från dSPACE GmbH. Systemet har visat sig fungera tillfredsställande i entestcellmiljö vid lyfthöjder större än 3 mm och varvtal lägre än 2500 rpm, även underförbränning.
FN och terrorism : En studie av världssamfundets policy sedan kalla krigets slut
The United Nations has a responsibility to combat acts of international terrorism, as they constitute a threat to international peace and security. In spite of this, there exists no generally accepted definition of the phenomenom within the UN. By examining resolutions on terrorism, this thesis aims to evaluate the UN?s policy on terrorism since the end of the cold war until 2003. The results show that the UN?s attitude towards terrorism eversince the end of the cold war has been condemning, but that the the events of September 11th 2001 has contributed to an even more firm approach to the problem.
Idrott, ungdomar och identitetsskapande : En studie i hur ungdomars identitetsskapande påverkas av utövandet av en lagidrott respektive en individuell idrott
The main objective of this essay is to examine how the identities of young people are influenced by their choice of an individual sport or a team sport.The following questions are the focus of the essay:? How does the sport influence the creation of an identity for active young people?? How will the choice of an individual sport or a team sport affect the development of an identity in young people who practises sport?To achieve the objective of this essay I have used a qualitative research approach. The empirical material has been collected with help of eight semi-structured interviews. Four of them were held with young people who practised swimming and the other four with young people who played soccer. The essay is structured from Derek Layders model regarding how to understand the social reality.
Fotbollens regler i skolans kontext
Uppsatsen handlar om huruvida dagens styrdokument för grundskolan medger en disciplinmodell som grundar sig på fotbollens spelregler. Uppsatsen bygger på textanalys, då den undersöker vad läroplan, skollag och övriga styrdokument säger om upprätthållandet av regler och dess konsekvenser i skolan. För att kunna jämföra upprätthållandet av regler i en skolkontext och en fotbollskontext valde jag ut fyra områden som återfinns i de båda kontexterna: demokrati, makt, trygghet och nolltolerans. Resultatet av undersökningen visar att det finns utrymme i de rådande dokumenten för att tillämpa Frisk-modellen, som jag kallar min disciplinmodell..

Förstår du vad jag menar? - En undersökning om kommunikation med hjälp av bilder mellan användare och systemutvecklare.
Ibland kan det förkomma problem mellan utvecklare och kund/användare då de tar
fram kraven till ett nytt system. En anledning till detta kan vara att
utvecklingsgruppen och användargruppen inte har samma kunskaper och
erfarenheter och talar då inte "samma språk". En lösning till detta problem kan
vara att ta hjälp av en mockup. En mockup är en fysisk och/eller interaktiv
modell av ett gränssnitt. I detta arbete har vi, med hjälp av intervjuer och
observationer, undersökt om detta hjälpmedel underlättar kommunikationen i
verkligheten..
