Near Field Communication (NFC) is a short range wireless communication technology that enables data exchange between devices. NFC is used in many different areas, from subway tickets to authentication systems. This paper presents possible security threats to Near Field Communication and documented attacks that have been used to target various NFC protocols. Weaknesses in different NFC protocols will be presented and suggestions on how to counter certain weaknesses will be discussed. This survey will be valuable for companies interested in protecting their data when using or planning to use NFC systems..

This is a bachelor thesis about arable land in Varberg, from sustainability and it?s relation to local government and management. Arable land has become more important as a natural resource from a global point of view and in concerns of higher demands of food supply, as a result of population growth, higher consumption worldwide and climate change. But the arable land in Sweden is being exploited an increasingly rapid pace and the arable land in Varberg is not an exception of this development. The issue is most topical and the discussion holds questions about a declining agricultural sector, the formal and administrative protection of arable land and because other interests of land use often is given higher priority in community development and planning.

Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime. This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

In this thesis we will discuss the importance of human resource development in smaller companies and if it will change from when the Swedish economy was in an economic boom and later on came to be in a recession. We choose to use a more qualitative approach for this research in order to conduct a more in-depth study of five smaller sized companies located on Gotland, Sweden. In order to limit our research we had as an ambition to answer these following questions:? What obstacles are there when it comes to human resource development and knowledge transference within smaller sized companies?? What can simplify or enable human resource development and knowledge transference within smaller sized companies?? Does the teaching process change to a more tacit human resource development between co-workers when there is less room for conventional human resource development?The result of the research came to show that the biggest barrier, when it comes to competence development within smaller companies, is time. However, our research also showed that a majority of the companies has changed from a more external educational plan to a more internal educational plan which focuses on keeping the human resource development within the company.

To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..

This thesis explores how the city of Gothenburg integrates and use social capital, defined through factors such as trust and cooperative networks, in its crisis preparedness strategies and how this can enhance the city's collective resilience. The study aims to contribute to the understanding of how social capital can be leveraged to strengthen crisis management and resilience in urban environments. The research analyzes existing quantitative data from the SOM-Institute regarding residents perceptions and self-reported preparedness actions and reviews Gothenburg's official civil defense plan for 2024?2027. By examining various aspects of social capital, including levels of trust and cooperative networks across different city districts and age groups, the analysis focuses on how social bonds and community contexts are considered in planning for handling and recovering from potential crises.

The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
