The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Det här är slutreflektionen för ett examensarbetet Recúrrens, skapat av Mikael Berglund och Johan Cederholm från Medieteknik och Joel Arwidson och Charlie Persson från digital ljudproduktion. Recúrrens är en novellfilm vi gjorde från idé till färdig film och vi kommer beskriva hela vår arbetsgången i den här slutreflektionen. I den andra, reflekterande delen, diskuterar vi hur arbetet gick, motgångar, framgångar och slutresutlatet. Bifogat finns även manuset och bildmanuset..

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

Purpose ? The purpose of the study was to examine how to promote a personal trainer in the fitness industry, as a personal brand, with digital media.Method ? To fulfill the purpose, the author have used three different methods. Both literature and quantitative and qualitative data in forms of a digital survey and interviews with two personal trainers regarding marketing and branding.Result ? Based on the collected literature and empirical evidence, facts could identify the importance of having a strong brand as a personal trainer, in order to recruit new clients. The result revealed that digital media is an excellent communication channel to nurture the relationship when you already have existing clients, but not when you want to recruit new customers.Implications ? This study is only developed through empirical data from a particular demography and a certain range, which could give a different result with other respondents.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

From 1710 to 1713 the plague raged through the Swedish province of Scania. Other studies have been made on how the disease affected the society during the epidemic. This study tries to focus on the recovery afterwards. How did the population and the farmsteads recover after the plague? Statistics from parish registers and cameral records show interesting patterns in the demography, and that the recovery was far from complete 1720.

Den långsiktiga bevaringen av digital information innebär nya utmaningar för svenska offentliga arkiv. I arbetet med att utveckla system för att hantera dessa utmaningar utgår svenska offentliga arkiv ifrån en konceptuell rammodell kallad Open Archival Information System (OAIS- modellen). Syftet med denna uppsats är att bidra med en ökad förståelse för hur svenska offentliga arkiv kan hantera de aktiviteter som ryms under bevarandeplanering (Preservation Planning) enligt OAIS-modellen. För att uppnå syftet har existerande forskning på området granskats och kopplats till bevarandeplanering enligt OAIS-modellen. För att kunna utvärdera den existerande forskningen har ny empirisk data samlats in genom kvalitativa intervjuer.

För att kunna utvärdera den existerande forskningen har ny empirisk data samlats in genom kvalitativa intervjuer. Viktiga slutsatser som har varit möjliga att dra i denna undersökning är att en migreringsstrategi är att föredra för svenska offentliga arkiv. Det kan även vara lämpligt för svenska offentliga arkiv att frångå OAIS- modellen och lagra teknisk metadata dels i informationspaketet och dels i en separat referensdatabas.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

The aim of this thesis is to analyze how small and medium-sized management consulting firms in Sweden work with human resource management during digital transformation. By interviewing companies, this study explores their approach to attracting, recruiting, and developing competence. The results showed that management consulting firms have good access to candidates, made possible by having a strong corporate culture and attractive working conditions - Crucial parts for attracting talent. Social media and networking are frequently used for marketing and attracting interesting candidates. Digital tools and social media showed to be useful during the recruitment process, but personal contacts and networking still play a central role.
