This thesis investigates how China has demonstrated its assertiveness in the South China Sea throughout Xi Jinping's second presidential term, from March 2018 to March 2023. Employing the theoretical framework of Offensive Realism, the thesis seeks to unravel the motivations behind China's assertiveness in the South China Sea, contributing to a nuanced understanding of its strategic behavi
The purpose of this thesis is to study how different political orientations in Swedish foreign security policy have been legitimized. After having pursued a policy of neutrality and non-alignment for 200 years, Sweden made a decision to apply for membership in the military alliance NATO. The investigated time periods are 2014 and 2022, during which Sweden has chosen completely different strategies
This study desires to display two speeches that were crucial to the 2016 EU-referendum in Great Britain. The two actors portrayed with one speech each are Boris Johnson and David Cameron, although the speeches weren’t given during the same time they are both highly accurate and significant to the referendum. The two speeches are applied to theories of analogies and also strategic narratives. Based
Climate change is a highly relevant topic in both politics and media. During 2019 the climate issue was much discussed and a recurring theme in Swedish news media, which have led me to speculate on how the climate question was portrayed during this year. Based on this, the study examines how climate change is framed in the media during 2019, using 32 articles published in three of Swedens biggest
The following study delves into the congruence of three major IR theories. Constructivism, liberalism and realism. It delves into this congruence by testing their compatibility under a single analytical framework. To best highlight these theories overlapping sides I have chosen to find variants of the theories that I believe to be most similar to one another. Furthermore, an idea analysis is condu
After the 2014 invasion of contested areas in Iraq by the so-called Islamic State (IS), the Yazidi community has suffered dire consequences. Genocide, sexual enslavement, forced religious conversion and forced displacement were some of these horrendous acts committed by IS against the Yazidi community and other minorities in Iraq and Syria. This thesis builds from the infusion of agonist theory in
This thesis investigates the intertwining of corporate social responsibility (CSR) discourse and the European Union's strategy for sustainable and circular textiles through a single case study and critical frame analysis (CFA). By doing this, concurring discourse between corporations and the institutions aimed at governing them can be problematised. Derived from conventional and contemporary C
This thesis explores the relationship between regional identity and its influence on EU support. Going beyond the common focus on decentralized countries or entire European contexts, the research specifically examines the influence of regional identity within the more unitary state of France. Building on established theory linking identity to EU support, the study distinguishes between exclusive a
The Council of Europe Convention on Preventing and Combating Violence against Women and Domestic Violence, known as the Istanbul Convention, was ratified by the European Union in 2023. However, five member states have not yet ratified. This essay investigates why some European Union member states have not ratified the Istanbul Convention, focusing specifically on Estonia and Lithuania using the mo
The work present in this master thesis relates to output feedback adaptive control and observer design of nonlinear systems, and in particular of robot manipulators. A continuous-time velocity observer and a discrete-time adaptive velocity observer for robots are shown, and an observer backstepping controller is also proposed, which can be used together with both the observers. The resulting close
Traditional Ethernet networks are not suitable for real-time communication due to the nondeterministic handling of the network communication. The reason for the nondeterministic behavior is the CSMA/CD access control protocol that is used when the media is shared. The protocol can cause collision in the transmission. If this happens the transmission ceases and after a random amount of time a ret
This master's thesis discusses the real-time issues of the operating system used by the Ericsson Bluetooth stack and the effects of replacing this operating system. The practical part consists of switching the operating system for the Ericsson Bluetooth stack and verifying if it still is operational and fulfils all timing requirements
This report is about the work that we have performed during Autumn 2001 at Botech AB. The purpose with this work was to further develop an existing product named Hubit. Hubit is a compact computer that is running Linux and has limited resources when it comes to memory and storage. Hubit is designed to monitor and collect data from controller systems. The two main objectives that we were about to d
Our problem considered was whether a virtual environment could be used for development of visual servoing control algorithms.
We have used a virtual environment for the comparison of several kinds of controllers. The virtual environment is done in Java, and it consists of two industrial robots, IRB 2000 and IRB 6, a camera stereo system with two cameras mounted on the end-effector of the IRB 6,
The thesis describes the development of a dynamic model of a microturbine system. The thesis is done in close cooperation with Turbec AB and the model is adjusted, tuned and verified against their microturbine T100. The microturbine unit consists of a compressor and a turbine connected on a single shaft to a high-speed generator. Moreover there is a combustion chamber, a recuperator and a gas/w
Brake-By-Wire means that the hydraulic-mechanical brake system in a car is partly or completely replaced with an electronic/electromechanical brake system. Brake-By-Wire systems are safety critical. A Brake-By-Wire system must also be fault tolerant and have a dependable real-time performance. One communication protocol that is developed to meet these requirements is called TTP/C (Time Triggered P
In this study, it is investigated how different parameters influence 16QAM modulation. The focus is on how different parameters in the Automatic Gain Control algorithm influence raw bit error rates, but other parameters such as frequency error and misplaced decision levels are also investigated. The goal is not to develop optimal parameter configurations, but to gain some understanding on what par
This report contains a study on inertial parameter estimation for application in robot control. Symbolic manipulation using Maple is applied to support the estimation efforts.
In this thesis a visual servoing approach for uncalibrated systems with 6 degrees of freedom (DOF) is evaluated. Assuming weak perspective, the observed motions of the robot end-effector are constrained to affine trans-formations in the image space. This allows us to express the control error directly in terms of an affine transformation in the camera images. By this approach, visual servoing is r
In order to minimise development time it is important to be able to implement and test control functions at an early stage in a project, even before the electronic hardware of the new product is available. For this purpose, a PC based rapid prototyping system including a graphical modelling/simulation tool and automatic C code generation for real-time simulations with hardware in the loop may be u
