Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.

Today there are commercially available databases with active features, i.e. active mechanisms are available for development of information systems. But the usage of active mechanisms is low in practice. This is due to the insufficient methodological support in analysis and design for developing ECA rule based software. It has been proposed that one of the most suitable ways to tackle this problem is not to develop new methods but to extend existing methodologies.In this thesis an extension of the Object Modeling Technique (OMT) is developed, called OMT-A, which is able to model active rules.

The purpose of this paper is to explore web use and web navigation behavior. This paper presents findings from qualitative research based on interviews and diarie studies. The basis of this study is Eli Parisers work about ?the filter bubble?. As personalization systems shape our experience of the web, based on who we are, our bubble of knowledge and information becomes smaller.

The aim of this report is to increase the knowledge and understanding of the problems within the production at AQ Enclosure systems, and thereby achieve a more stable flow throughout the whole process, a better working environment and better competition advantages. The internal flow along with the external cooperation is very important for the company, because it views flexibility and short leadtime as it is the most important competitive means. The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

SAAB Support and Services, som är servicecenter för flygplanskomponenter, utför idag huvuddelar av sina mätningar manuellt, mätningar som ibland kan ta upp till fyra dagar. För att höja noggrannheten samt öka effektiviteten köpte de år 2007 in ett automatiskt testkoncept från MK Test systems.I examensarbetet har vi först undersökt den inköpta utrustningen.Sedan har vi tagit fram rutiner för kalibrering av utrustningen som klarar SAAB:s krav. Därefter har vi arbetat fram kravspecifikationer och instruktioner för hur utrustningen ska användas. Under arbetets gång har vi samlat in information för att kunna göra en utvärdering av hur lämplig utrustningen är att använda för att testa flygplanskomponenter.Arbetet resulterade huvudsakligen i tre st manualer som går igenom tre olika områden; kalibrering, kablagetest och ett standardtest för t.ex.paneler och styrboxar..

Denna rapport är resultatet av ett examensarbete som utförts av Fredrik Eriksson och Johan Hultgren, studenter vid fakulteten för teknik- och naturvetenskap på Karlstads universitet. Arbetet omfattar 22,5 högskolepoäng och är den avslutade delen på Maskiningenjörsprogrammet respektive Innovations- och designingenjörsprogrammet.Arbetsgivaren har varit Partnertech Karlskoga AB som fick ett uppdrag från BAE Systems Bofors angående möjligheten att kostnadseffektivisera mellankaliber 40mm och 57mm kulspränggranater genom att titta på alternativa material och tillverkningsmetoder. Produkterna som arbetet behandlar går under benämning ytterhylsa och är en delkomponent av den färdiga kulspränggranaten. Ytterhylsorna tillverkas idag från massiv rundstång av material SS2242 (Orvar Supreme) genom skärande bearbetning i CNC-svarv och anses idag vara för dyr för att uppfylla de krav som ställs på nästa generations ammunition. Det får inte förekomma några dimensionsändringar på ytterhylsorna och den färdiga konstruktionens funktionalitet och säkerhet skall vara oförändrad.En väl genomförd research var ett måste för att kunna gå vidare med problemet.

Syftet med detta arbete är att designa och utvärdera ett stridssystem för ett rollspel, som skall ha en högre grad av meningsfulla val än de två kommersiella rollspel som utvärderas tillsammans med det egenutvecklade stridssystemet. För att få en högre grad av meningsfulla val så designas stridssystemet efter två teorier: triangulära val och multiple-dice systems. Graden av meningsfulla val utvärderas genom strukturerade intervjuer där respondenterna svara på en enkät.Utvärderingen visade att det egenutvecklade stridssystem inte uppnådde en högre grad av meningsfulla val än de två kommersiella stridssystemen.Rollspelet bör i framtiden modifieras för att korrigera de problem som framkom genom utvärderingen. Utvärderingsmetoden som användes i arbetet kan utvärdera graden av meningsfulla val i alla typer av spel..

SummaryBackground: Management control is important for all kinds of activities, both in trade and industry and in the public sector since you must economize on scarce resources. There are nevertheless many different views on management control, which have changed with the times. With regard to the public sector in Sweden, the management control systems have changed radically the last half century, especially from the 1980s, due to depressions and increased focus on effectiveness. New approaches have been taken by many municipalities and county councils, both in Sweden and internationally, where the former management control systems have been abandoned in favour of result control, target costing, and activity-based-costing, for example. Another new approach has been the Balanced Scorecard, which was introduced by Kaplan & Norton in a pioneering article in 1992.The Balanced scorecard is a multidimensional tool, originally intended to be used in trade and industry, but with regard to its nature, it has been adopted even by many non-commercial organizations, especially in Sweden.

This final thesis is carried out at BAE Systems Hägglunds in Örnsköldsvik. The mission was to construct and integrate a new semi-active damping unit in the terrain vehicle BvS10. Questions that came up during the process, among others, was how to mount the damping unit to the vehicle in a flexible way without exposing it to unnecessary wears.A generation of the concept is made in 3D using CATIA V5 of a possible solution to the problem. The idea is to weld the unit to the skid girder which is one of the main constructions of the track system. In this way the damping unit will come closer to the track system, which will partly protect it from impacts from below and minimize current problems with breaking forces in the torsion shafts.The complete construction was then analyzed, first by theoretical calculations and then with the FEM-tools in CATIA V5.

This report is a thesis on requests from Sandvik Mining and Construction (SMC) in autumn of 2012. The goal of this work was to study the feasibility of creating and implementing an Equalized preventive maintenance program in SMC maintenance operations and reduce downtime for preventive maintenance (PM). To investigate whether this was possible, the authors studied the current procedures for the PM. The authors have collected and analyzed all relevant information within the maintenance department reporting system as well as through interviews determined whether it is practical to introduce a Equalized PM programs. The authors had also studied the possibilities to entrust part of the maintenance work to the operators of the machine cells.

The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.

Abstract: After their introduction, technical systems designed for Situational Awareness have changed the possibilities on the battlefield. Today, Swedish tanks use a system known as the TCCS. This system offers many advantages to a tank platoon, but does it also bring disadvantages? This essay examines pros and cons with the TCCS. To find these the author uses a Swedish Armed Forces analyze model in a comparative study.

Villkoren i dagens samhälle förändras snabbt och miljön som beslutsfattare måste hantera blir allt mer komplex, detta samtidigt som tiden för att fatta beslut krymper. För att beslutsfattare ska klara detta kan de ta hjälp av verktyg. Vi har undersökt om geografiska informationssystem (GIS) är ett verktyg som effektiviserar framtagandet av ett beslutsunderlag när problemet är geografiskt relaterat. Undersökningen har genomförts som en fallstudie på fyra olika organisationer där vi jämfört processen vid skapandet av ett beslutsunderlag före och efter införandet av GIS i organisationen. Slutsatsen vi drar av vår undersökning är att geografiska informationssystem effektiviserar framtagandet av beslutsunderlag när problemet är geografiskt relaterat..
