Abstract

The possibility to accurately position without the need for a position sensor makes stepping motors very appealing for positioning applications. However, drawbacks of the cheap and easy to use open-loop control are the continuous risk of missing a step due to overload, the high torque ripple and low efficiency. In addition, BLDC motors are particularly outspoken for speed varying applications. Literature shows that the control method can be improved by controlling a BLDC motor with sinusoidal currents instead of square-wave currents. Unfortunately, feedback techniques typically used in BLDC motors to determine the commutation moments are inadequate for sinusoidal current setpoint generation.In this study, a sensorless feedback mechanism indicating the actual load and a controller preventing step loss, without noticeably increasing the cost, is proposed for stepping motor applications. In parallel, a computationally simple sensorless method that uses sinusoidal currents to increase the efficiency of BLDC motors is developed.

Abstract

International migration is a complex and dynamic phenomenon with wide-ranging implications for the receiving countries. As implied by the title, this doctoral dissertation attempts to approach the subject of international migration from different angles and perspectives. In particular, each of the three main empirical studies of this dissertation investigates a specific topic of the economic, social and political consequences of international migration in the European region. This is in order to highlight the importance of multidimensional research that is able to give a bird’s eye view on the theme.

The first study examines whether the effect of cultural diversity on economic performance of European regions is influenced by the level of generalized social trust and individuals’ trust in public institutions. The second study investigates how the origin and the skill level of immigrants in European regions affect natives’ attitudes toward them. The last study examines the impact of international immigration on electoral support for the radical right in Dutch municipalities.

Abstract

The chemical (related) industry is one of the largest industries in the world. At this moment this industry is mainly petrochemically based. Due to a rising shortage of petroleum and the stress between its function as fuel (source of energy) and its function as raw material (source of chemical building blocks), new strategies are deployed with respect to alternative raw materials that could lead to chemical building blocks.

Oleochemistry (centered on carbon containing molecules from natural oils and fats) seems an interesting way to obtain valuable chemical building blocks. A very interesting point is that it is a natural source of desirable long carbon-chain molecules, which can be further derivatized. The oleochemical approach has however also some disadvantages. A first important issue is the food versus fuel and/or food versus raw material discussion. The second issue is that there is a lack of long chain multifunctional, more specifically long chain α,ω-bifunctional molecules occurring in nature. Yet, such molecules can be used in high-value applications such as biopolymers and biolubricants.

As long chain bifunctional compounds, like α,ω-dicarboxylic acids are not provided by nature in sufficient amounts, it is important to develop a process to obtain these compounds in an environmentally friendly and economically viable way. It is important to design a process with an environmentally friendly catalyst and to optimize the process in such a way that not only edible clean fats/oils are used as starting material but also inedible fats/oils and maybe used oils/fats (used cooking oil).

This PhD work contributes to the valorization of unsaturated renewable materials into industrially relevant products. More specifically, the goal of this PhD work was to realize a sustainable method for the preparation of long carbon chain α,ω-bifunctionalized molecules starting from unsaturated long chain fatty acids and/or their derivatives. Two different methods to produce α – ω long chain building blocks were investigated: (1) the shift of mid-chain double bonds in derivatives of unsaturated (free) fatty acid esters by means of hydroboration-isomerization and (2) the synthesis and derivatization of long chain unsaturated dialkyl ethers.

The largest application of α,ω-bifunctional compounds (short as well as long type) can be situated in the production of biopolymers. Most of said biopolymers are based on polycondensation reactions (polyamides, polyesters, ...). Depending on the chain length of the α,ω-bifunctional compound the amount of polarity can be controlled in the biopolymer that has a polar repeating unit (e.g. ester group) that will be “diluted” with the long apolar hydrocarbon chain. At the moment a lot of apolar (petro)polymers are used that are not biodegradable (PE, PP, etc.). From literature it is found that most of all produced apolar (petro)polymers are not recovered and thus induce environmental pressure. In case long chain α,ω-bifunctional molecules with a high number of –CH2- groups in the chain could be produced, polymers could be made that could mimic the apolar (petro)polymers. This polyester type “Pseudo-PE” would be degradable and hence will give raise to less environmental pressure.
