Dagens moderna organisationer driver vanligtvis en kostsam IT-baserad infrastruktur. De besitter högpresterande funktionalitet och säkerhet för att garantera att de dagliga operationerna fortskrider. Mjukvarubaserade lagringsplattformar är ett alternativ som kan användas för att reducera dessa kostnader. Genom att efterlikna avancerad teknik som redan existerar i traditionella lagringsplattformar kan detta implementeras som mjukvara på commodity hardware i syfte att uppnå samma funktionalitet. Ceph är ett alternativ som numera implementeras och ämnar erbjuda detta val.

Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.

Bachelor thesis, Controller, Program of Master of Science in Business and Economics, School of Business and Economics at Linneaus University in Växjö, Sweden, Course Code: 2FE13E:3, Spring 2012 Authors: Jacob Cedergren, Adam Pettersson, Hampus SkelterwijkSupervisor: Anders JerrelingTitle: The ERP-systems impact of the management control - a case study of VIDA AB Original Title: Affärssystemens påverkan på ekonomistyrningen - en fallstudie på VIDA ABBackground: New technology has given businesses new opportunities to use and store information and the current information systems has changed the way of working in more or less all sectors and operations. ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation. The possibility to protect oneself against attacks from the outside becomes increasingly difficult.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

Title: Co-operative, prevent or complement? - An essay on the relationships between control systems. Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between control systems and how they related to each other, based on an operationalization of the control systems. Research question: What are the control systems relations to each other? With regards whether control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different control systems and control mechanisms associated with each control system.   Research methodology: The method was based on three different data collection methods. These methods were observations, documentation, and semi-structured interviews.Conclusions: It is concluded that the control systems has comprehensive relations. Control systems have more, than one, relation to each other..

This thesis is an attempt to study whether if problem-oriented teaching implies a moreadvanced use of school libraries than other teaching methods.Teachers have been interviewed about what kind of information they and their pupils need,and where they find their information. Another question is whether the problem-orientedteaching method makes it easier for the pupils to find information in school libraries thanother teaching methods do.The result of the study is that a problem-oriented teaching method creates opportunitiesfor the school library to become an important place for information retrieval. This teachingmethod is a major, but not the only determinal factor. Other contributing factors could beteamwork between teachers and school librarians and the existence of learning aids..

This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.

Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
