The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.
Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab
The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Utvärdering av nätverkssäkerheten på J Bil AB
Detta examensarbete är en utvärdering av nätverkssäkerheten hos J BiL AB, både på social och teknisk nivå. Företaget är beroende av säkra Internet-anslutningar för att nå externa tjänster och interna servrar lokaliserade på olika geografiska platser. Företaget har ingen IT-ansvarig som aktivt underhåller och övervakar nätverket, utan konsulterar ett externt dataföretag. Syftet med examensarbetet är att utvärdera säkerheten, upptäcka brister, ge förbättringsförslag och till viss del implementera lösningar. För att undersöka säkerheten har observationer och intervjuer med personalen gjorts och ett flertal attacker mot nätverket har utförts.
Motivation. En studie av motivationsfaktorer tillämpade på volontärer
Titel: Motivation. En studie av motivationsfaktorer tillämpade på volontärer Författare:Ronny Adolfson, Patrik Gran och Axel Lindblom Handledare: Christer Eldh och Ola Thufvesson Syfte:Syftet med denna uppsat's är att undersöka vilka faktorer som motiverar volontärer och om dessa kan förklara's med klassisk motivationsteori. Vi vill få ökad kunskap om vilka drivkrafter det är som motiverar volontärer att prestera utan att få någon nämnvärd ersättning. Frågeställningar: Är klassisk motivationsteori tillämpbar på volontärer?Vad karaktäriserar volontären's motivationsfaktorer? Metod: Vi har använt os's av en kvalitativ metod och där foku's har lagt's på intervjuer och artiklar.

Produktspårning med RFID : Konceptutveckling och utvärdering
The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Kostnadsnyttoanalys över införandet av passiv RFID inom Försvarsmaktens beklädnadsförsörjning
The Armed Forces is looking to improve control of where articles are and the monitoring of their condition within its clothing supply. That is why Försvarets Materielverk is working on a motion to tag the Armed Forces clothing with passive RFID-tags. A cost/benefit analysis has been made in this report in order to find out whether the investment is economical justifiable and what costs and benefits arose. The analysis tool that was used is based on the PENG-model. The analysis had three scenarios with the difference that each scenario included various amounts of clothing to tag. There has also been made an analysis where only the benefits regarding decreasing amount of lost clothes and simplified inventory were included.The result of the first analysis was that none of the scenarios was profitable during the first year.
Konstruktion och utformning av skydd till spolverk
This thesis has been carried out in cooperation with Burseryds Bruk AB.Burseryds Bruk is a company that manufactures steel strapping.

Fast etableringsställe : En skatteplanerares dröm?
This master?s thesis will examine the concept of ?fixed establishment? in VAT-law. The concept can be found in the new EC-directive on the common system of value added tax, however it has existed for thirty years in previous directives. Despite this, the legislator has never provided a proper definition of the concept. Its meaning has therefore evolved through the case-law of the ECJ.The Court has put forward a number of criteria which are all to be met if a fixed establishment is to be at hand.

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.
Logistisk kulmination - en eller två sidor av myntet? : En betraktelse utifrån ett annorlunda perspektiv
Logistic Culmination ? One or Two Sides of the Coin?An Observation From a Different Point of View Logistic culmination can be compared to a stretched rubber band. If combat units moves in direction away from the supplies the rubber band will gradually stretch. The rubber band will eventually burst and at that point the logistic culmination will be a fact. But if the rubber band was to be let go before bursting, it will instead be contracted.
