Belo Gomes Brito, C. (author), Teuwen, Julie J.E. (author), Dransfeld, C.A. (author), Villegas, I.F. (author)This paper evaluates the potential of changing the welding force and the compliance of the energy director (ED) to reduce the effects caused by misaligned adherends, which were: increased through-thickness heating, reduced size of welded area and increased heating time. In the methodology that was followed, we welded adherends misaligned by...journal article 2023

Bosma, Detmer (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)A dedicated signal and data processing chain is proposed for a fully polarimetric Doppler surveillance S-band radar to extract the polarimetric signatures of moving targets. To extract the target’s polarimetric features, detection, clustering, and tracking steps are realized for a multi-target environment in the range-Doppler domain. A dedicated...journal article 2023

Mohandas, N.K. (author), Giorgini, Alex (author), Vanazzi, Matteo (author), Riemslag, A.C. (author), Scott, S.P. (author), Popovich, V. (author)This study investigated the in-situ gaseous (under 150 bar) hydrogen embrittlement behaviour of additively manufactured (AM) Inconel 718 produced from sustainable feedstock. Here, sustainable feedstock refers to the Inconel 718 powder produced by vacuum induction melting inert gas atomisation of failed printed parts or waste from CNC machining....journal article 2023

Cheng, L. (author), Nokhbatolfoghahai, A. (author), Groves, R.M. (author), Veljkovic, M. (author)The performance of the Acoustic Emission (AE) technique is significantly dependent on the sensors attached to the structural surface. Although conventional commercially AE sensors, like R15a and WSa sensors, have been extensively employed in monitoring many different structures, they are unavailable in restricted-assess areas. In contrast,...conference paper 2023

Wang, L. (author), Li, Erlei (author), Zhou, Zongyan (author), Zhang, Baicheng (author), Yu, Aibing (author)Powder bed fusion additive manufacturing has been applied to the fabrication of functionally graded materials. A new design that allows the material composition to change along the direction perpendicular to the powder spreading has been reported in the literature. Based on this design, this work examines the quality of the graded spread...journal article 2023

Hao, Xuan (author), Qiu, Yubao (author), Jia, Guoqiang (author), Menenti, M. (author), Ma, Jiangming (author), Jiang, Zhengxin (author)Land use–land cover (LULC) is an important feature for ecological environment research, land resource management and evaluation. Although global high-resolution LULC data sets are booming, their regional performances were still evaluated in limited regions. To demonstrate the local applicability of global LULC data products, six emerging LULC...journal article 2023

de Alvear Cardenas, Jose Ignacio (author)Despite the camera being ubiquitous to unmanned aerial vehicles (UAVs), it has not been used for fault detection and diagnosis (FDD) due to the nonexistence of UAV multi-sensor datasets that include actuator failure scenarios. This thesis proposes a knowledge-based FDD framework based on a lightweight Long-Short Term Memory network that fuses...master thesis 2022

Baldauf, L. (author)Cells are the fundamental units of life. They make up all living things, from bacteria that live in the soil, to archea that give thermal springs their bright colors, to trees and humans. All of these cells share some common functions: they build themselves from basic building blocks, following the instructions of their genetic blueprint, and...doctoral thesis 2022

Domhof, J.F.M. (author)The aim of the thesis is to develop methods and algorithms for the development of a robust perception system that is capable of dealing with adverse weather conditions. Robust environmental perception is important in order to guarantee safety for the automated vehicle and the road users in the neighborhood. To create a robust perception system,...doctoral thesis 2022

Smedema, Jette (author)<b>Background</b><br/>Adolescent idiopathic scoliosis (AIS) with a Cobb angle larger than 45° is a spinal deformity that needs surgical treatment to stop progression and reduce pain. Spinal fusion is a surgical procedure where rods are attached to the spine through screws to diminish the Cobb angle.<br/><b>Objective</b><br/>The metal rods are...master thesis 2022

Stolk, Toon Stolk (author)There is no denying that the ever-increasing demand in space endeavours calls for more sustainable exploitation of the space environment. Approaches to mitigate space debris, such as ADR, are frequently suggested. Most of these proposals suggest a single sensor approach to provide accurate and continuous shape and pose estimation of the target....master thesis 2022

van de Loo, Koen (author)The urgency for decarbonization of the energy grid is ever increasing and fossil energy sources must be replaced by sustainable sources of energy to prevent detrimental levels of global warming. Renewable energy sources wind and solar show potential and contribute to decarbonization but are intermitted and require storage solutions that are...master thesis 2022

Blok, Robin (author)An improvement for pedicle screws would be if the screws can directly transfer their forces to the strong cortical bone of the vertebra, rather than through the softer cancellous bone. This approach requires the creation of a curved trajectory through cancellous bone. The goal of this project is to adapt the flexible oscillating drill design of...master thesis 2022

YANG, Xuzhou (author)As unmanned aerial systems (UAS) turn into a full-fledged industry, the sky will be much more crowded in the future. Large-scale UAV applications make reliable UAV navigation a pressing need. Traditionally, global navigation satellite system (GNSS) is extensively used as the primary positioning, navigation, and timing (PNT) service. However,...master thesis 2022

Yang, Xinyue (author)To obtain and fully use long series of high-precision observations of water balance components, it is necessary to quantify and reduce random and systematic data errors. This thesis applies and evaluates a previously developed data fusion methodology for bias-correcting and noise-filtering remote sensing observations of water balance variables...master thesis 2022

van Oorschot, Marijn (author)Spacecraft navigation and control is difficult in deep space operations. Especially around asteroids, the irregular gravity field increases the difficulty of estimating the spacecraft trajectory. Autonomous navigation can increase the safety and accuracy for orbit proximity operations. Furthermore, it eliminates the need for continuous...master thesis 2022

Baratam, Srimannarayana (author)Multi-class road user detection using the next- generation, 3+1D (range, azimuth, elevation, and Doppler) radars has been shown feasible, thanks to the increased density of their point clouds and the inclusion of elevation information. However, object detection networks using LiDAR (64-layer) point clouds still dominate the performance metrics....master thesis 2022

Apra, Irène (author)Automated reconstruction of detailed semantic 3D city models is challenging due to the need for high-resolution (HR) and large-scale input datasets, the ambiguous definition of the ensuing model, the intricacy of the processing pipeline, and its costs. Furthermore, existing methods mainly focus on geometry rather than semantics. Detailed...master thesis 2022
