Zhang, QI (author)In image search, an algorithm tries to identify images in a database that are similar to a query image. Image search has numerous applications. For example, image search can help historians find images of a historical building from a large image database of buildings worldwide. Feature extraction and nearest neighbors methods are standard steps...master thesis 2022

Zhang, Peter (author)Peer-to-peer trading and energy communities have garnered much attention over the last few years due to the wider spread of distributed energy resources. Much research has been performed on the mechanisms and methodologies behind their implementation and realisation. However, the efficiency and micro-structure of trading in such markets raise...master thesis 2022

Zhang, Yixuan (author)One of the most important problems that needs tackling for wide deployment of Automatic Speech Recognition (ASR) is the bias in ASR, i.e., ASRs tend to generate more accurate predictions for certain speaker groups while making more errors on speech from others. In this thesis, we aim to reduce bias against non-native speakers of Dutch compared...master thesis 2022

Zhang, Xiangxie (author)Location information is essential for the ViT model. Image data has three types of location information: absolute location, relative direction, and relative distance. Various position embeddings methods have been used to introduce location information to the ViT model. Some existing methods are absolute position embeddings, relative position...master thesis 2022

Zhang, Yuanyuan (author)Automatic Speech Recognition (ASR) systems have seen substantial improvements in the past decade; however, not for all speaker groups. Recent research shows that bias exists against different types of speech, including non-native accents, in state-of-the-art (SOTA) ASR systems. To attain inclusive speech recognition, i.e., ASR for everyone...master thesis 2022

Zhang, Yuning (author)Quantum decoherence is one of the most substantial challenges on the way to fullyfledged quantum technology. Noise mitigation based on dynamical control techniques, aside from error correction, is known to be another effective approach to protect qubits from decoherence. In this thesis, we studied the dynamics of a spin qubit interacting with a...master thesis 2022

Zhang, Annie (author)In this research, a few initiatives were completed with practical industrial information and water samples from Heineken®. A Python model was built for an imaginary bottle washer, and tested with difference operational variables under the four testing scenarios. Based on the operational information fromthe Spanish brewery, a second Python model...master thesis 2022

Zhang, Zhiyue (author)The rapid growth of the Internet use has allowed social networks to become the most effective means for marketing, leading to the emergence of "viral marketing" as a business model. The biggest challenge that is facing "viral marketing" is selecting seed users from the whole user set to form a "seed-set" to spread the influence and maximize the...master thesis 2022

Zhang, Chenyan (author)Modern communication systems have a strong need for low-cost and high-stability frequency references. Although low-cost crystal oscillators can easily be realized and are available to the market in large quantities, crystal oscillators with frequency stability in the ppb(10^{-9}) range over a wide temperature range are only available at high...master thesis 2022

Zhang, Jiawen Zhang (author)Currently, as the utilization of offshore wind energy continues to increase, floating wind turbines are expected to be widely used. As the fixed system of the turbine, the safety of the mooring chain has gradually attracted the attention of researchers. Mooring chains immersed in seawater are mainly subjected to various mechanical loads and...master thesis 2022

Zhang, Shubo (author)The scheduling algorithm of the printer is an important factor that affects printing efficiency. For current printers, paper scheduling often follows the first-in-first-out principle, so it is often not optimal. The printer system is a type of semi-cyclic discrete-event system with synchronization but no concurrency. The system contains a set of...master thesis 2021

Zhang, Ying (author)For radar imaging, resolution and dynamic range are two critical metrics to measure image quality. MIMO array exploits the spatial diversity of transmitters and receivers to achieve high cross-range resolution with fewer antennas than array-based imaging.<br/> Generally, to make full use of the sparsity, at least the transmit array or the...master thesis 2021

Zhang, Ziru (author)E-bike sharing has gradually gained popularity in recent years, while the research in this field is still quite limited. This study applies data-driven methods, mainly demand pattern analysis, to facilitate the development of operational strategies in a cost-effective and operator-friendly way. Demand pattern is analysed in an innovative spatial...master thesis 2021

Zhang, Le (author)Estuarine intertidal flats comprise valuable ecosystems and act as an important sediment source for the adjacent salt marsh systems. However, accelerating sea-level rise threatens the mudflats and associated ecosystems, where the mudflat accretion lag behind sea level rise. A reliable forecast on the morphological developments of the mudflat...master thesis 2021

Zhang, Yixin (author)In this design, we propose a new method to process the large static signal in the received signal of Doppler ultrasound brain imaging. Through a reproduction-compensation method, a medium resolution ADC and a DAC are used to replace the high-resolution ADC used in the past for the dynamic Doppler signal observation.master thesis 2021
