The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..

Performance Management är en process som syftar till att säkerställa att alla inom en organisation arbetar i samma riktning. Detta uppnås genom att öka tydligheten kring organisationens strategiska mål samt koppla dessa till medarbetarens individuella mål. Vidare är det viktigt att kommunicera vad som förväntas av medarbetarna i termer av arbetsprestationer samt hur detta skall uppnås för att lyckas med uppdraget att minska gapet mellan medarbetares arbetsprestationer och ledningens ambitioner (Armstrong & Baron, 2005).Uppsatsens övergripande syfte är att undersöka vilka erfarenheter ledare inom det multinationella telekom- och IT-företaget Logica har av att arbeta med Performance Management samt vilka delar av implementeringen som har varit lätta respektive svåra att genomföra. Vidare vill jag undersöka hur organisationen ytterligare kan förstärka arbetet med Performance Management-processen baserat på ovanstående.Den empiriska undersökningen har genomförts med kvalitativ metod i form av tre stycken fokusgruppintervjuer med ansatsen Experiential Focus Group. Som komplement till fokusgruppintervjuerna har analys av interna dokument som beskriver Performance Management-processen inom Logica, genomförts.Resultatet av undersökningen visar att ledarnas upplevelser av Performance Management-processen varierar beroende på vilken typ av arbetsgrupp man är ledare för.

Work, especially that in complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization and so forth. Still, people in Nuclear Industry seem to think safety results from people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter "rule following culture". None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience.

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.

The collection of hazardous waste from the household around Swedish municipalities varies. 1% of the households waste is hazardous waste. It has hazardous features that can give bad consequences for the nature and human health if we don?t collect it and treat it. Therefore the law controls it, the municipalities have responsibility for the household waste.

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.

It´s important when you are about to build a new stable or just increasing your production that you choose the right housing system and that it fits your own farm. In this study I have put together facts about different housing system for fattening bulls in order to get a clearer picture of witch system is the most suitable for my own farm depending on the conditions I have. The background of this work is my own interest for breeding bulls and I will hopefully increase my own production. Due to this I wanted to learn more and increase my knowledge about different housing systems. Through a literature study I have found out the facts about the housing systems I find suitable for housing bulls.

Cloud Computing är det stora modeordet i IT-världen just nu. Det har blivit mer och mer populärt på senare år men frågor har uppstått om dess prestanda och säkerhet. Hur säkert är det egentligen och är det någon större skillnad i prestanda mellan en lokal server och en molnbaserad server? Detta examensarbete tar upp dessa frågor. En serie prestandatester kombinerat med en litteraturstudie genomfördes för att få fram ett resultatet för detta examensarbete. Denna rapport kan komma att vara till nytta för de som har ett intresse av Cloud Computing men som saknar någon större kunskap om ämnet.
