Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Som ett verktyg för organisationer att möta en alltmer komplex omvärld och komplexa problem har Ronald A. Heifetz (1994) utvecklat Adaptive Leadership Theory. Syftet med föreliggande studie var att undersöka om Adaptive Leadership Theory kunde användas för att få en förståelse för varför kommunikationsproblem återkommer. Frågeställningen var; Kan det undersökta företagets återkommande kommunikationsproblem förklaras, utifrån Heifetz? (1994) teori, med att medarbetarna har identifierat och hanterat dem felaktigt? Data samlades in genom kvalitativa intervjuer på en svensk arbetsplats och analyserades enligt en induktiv tematisk analys.

The leadership within healthcare is a constantly discussed subject. The discussion today is evolving around the physicians' lack of strive towards becoming managers within healthcare organizations. Furthermore the leadership that the nurse practice when becoming manager is on the other hand not discussed. The purpose of this study is to describe important factors of the leadership the nurse practice upon physicians in a healthcare organization as well as to explain why that is. To fulfill this purpose, we have used a qualitative case study research design including a private Swedish healthcare company.

Due to globalization, decentralization and the capitalist system's need to physical location cities have become increasingly important economic spheres during thee last decades. City mayors are seen as increasingly important actors, who can shape the future economic development of their cities through networking with businesses and strategic policy development. Therefore several European countries have introduced mayor reforms to enable mayors to take a bigger responsibility for the local development. These reforms raise interesting questions concerning what leadership changes they produce at the local level and if there is a difference between local leaders and leadership in different countries. This paper further explores the connection between the local leader and the locality since this relationship often has been neglect in studies concerning mayor reforms.

The effects of social media usage in a professional context, specifically the effects on social media usage in relation to leadership have been studied in order to determine weather or not usage can be productive for leadership in general. The study concludes that there are several benefits as well as drawbacks to leadership in using social media, but has yet to conclude weather productive or not. This study gives an overview of a relatively unexplored subject.Leadership in terms of leader, communication and group dynamics have been defined and explained in accordance with existing literature. A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

AbstraktTransformativt ledarskap och empowering ledarskap undersöktes i en kvantitativ studie där 89 medarbetare vid ett större skogsföretag i Sundsvall besvarade en enkät och skattade sina chefers ledarskapsbeteende. En principal komponentanalys visade stöd för att det var två olika typer av ledarskap, och multipla hierarkiska regressionsanalyser visade stöd för att effekterna av transformativt ledarskap och empowering ledarskap var ledarskapseffektivitet och tillfredställelse med arbetsledningen. Resultatet av studien överensstämde väl med tidigare internationell ledarskapsforskning och indikerar att det går att predicera vilka effekter ett ledarskap hade på medarbetarna och därmed indirekt på medarbetarnas prestationer..

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Purpose of the study was to illustrate how emotional competence can be important for leadership and to explore the possibility of improving emotion perception ability after training. Participants in this study were 40 managers, divided into control and experimental group, within public administration. The participants implemented a data-based emotion perception test, which were done twice at every occasion, with intervention consisting of information or education between test- and retest. The result showed a clear improvement after intervention, in which no difference was found between control and experimental group, which has been discussed on the basis of the likelihood of a training effect occurred between test-retest. Conclusions about emotional competence or leadership ability could not be drawn from the results of the emotion perception test.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

This bachelor thesis delves into the role and impact of cultural dimensions, identity and leadership on post-merger acquisition in Sweden through an in-depth analysis of two companies that have undergone acquisitions or mergers. Using an abductive method, where theories are continuously adapted based on empirical data, qualitative information was gathered through semi-structured interviews with managers and employees from the two companies. The study aimed to gather well-founded insights on how corporate cultural dimensions, identity and leadership are experienced by individuals during the merger. By examining culture, leadership and identity in three different time phases of the integrationprocess, a comprehensive understanding of the integration process was achieved. The results of the study highlight that cultural factors such as leadership, culture, and identity play a central and crucial role in mergers and acquisitions. By considering and managing employees' and leaders' identities, organizations can create a sense of coherence and continuity despite changes.

AbstractAll headmasters want to lead teachers so that the students will achieve their own goals as well as the goals of the education. The salutogenic leadership is a way to lead in the right direction. This type of leadership depends on Antonovski?s (2005) theory of Sense of coherence. The theory of Sense of coherence is built on the concepts of comprehensibility, manageability and meaningfulness.

Few generations have gotten as much media attention as Generation Y. Growing up in the digital age Generation Y has become very different from previous generations. An interesting topic is if this is reflected in the way Generation Y act as leaders. The purpose of this study is to describe what kind of leadership Generation Y prefers, to explore how individuals belonging to Generation Y act as leaders and finally to investigate if there is a discrepancy between these two perspectives and if so try to understand it. By reviewing existing research and conducting depth interviews with employees and managers at a Swedish bank we recognize preferences in a number of categories, which Generation Y require from leaders.
