Zhang, A. (author)Bio-mediated methods, such as microbially induced carbonate precipitation (MICP) and enzyme induced carbonate precipitation (EICP), have gained considerable attention as alternatives to invasive ground improvement techniques. MICP and EICP use biogeochemical processes to drive carbonate precipitation and bind soil grains, thereby improving the...doctoral thesis 2025

Zhang, Y. (author)Wind energy is one of the most important renewable energy sources, effectively addressing climate change issues and promoting sustainable development on a global scale. Blade failures may cause long shut-down times and may present a safety hazard. Continuous and real-time monitoring of the blade conditions is helpful for finding blade damage at...doctoral thesis 2024

Zhang, M. (author)Food and medicines are two of the most essential categories of goods for human beings, providing vital nourishment and healthcare. However, as these products are commercialized and distributed on a global scale, consumers face the threat of counterfeit and deteriorated products. In response, this dissertation presents four prototypes consisting...doctoral thesis 2024

Zhang, H. (author)In recent decades, dielectric lens antennas have been more and more adopted and developed for sensing and imaging applications at sub-millimeter (sub-mm) wavelengths because they can achieve high gain while keeping their physical size and weight acceptable at these wavelengths. More recently, as low-loss and low-cost lens materials have become...doctoral thesis 2024

Zhang, Y. (author)Freight transport faces a threefold challenge of limited resources, increasing demand for efficient goods movement, and the pressing need to meet ambitious emissions reduction targets in ever shorter timelines. To address these challenges, the industry requires urgent innovation and the adoption of new technologies and logistics systems to...doctoral thesis 2023

Zhang, M. (author)A remarkable accomplishment of human beings in recent centuries is the extension of their average lifespan, for example by improved living conditions. A downside of this achievement is that aging-related diseases, such as Alzheimer’s disease (AD), have risen, and as a consequence are impacting the lives of an increasing fraction of individuals....doctoral thesis 2023

Zhang, Y. (author)In order to compensate the limited availability of raw material resources and meet the growing demand for decreasing CO2 emissions during cement and concrete productions, a practical method is to decrease the clinker content in cement. This strategy mainly consists of substituting a part of the clinker with supplementary cementitious materials ...doctoral thesis 2022

Zhang, P. (author)Short pitch corrugation is a (quasi-) periodic rail surface defect with shiny crests and dark valleys. It primarily occurs on tangent tracks or gentle curves with a typical wavelength in the range of 20-80 mm. Short pitch corrugation excites high-frequency wheel-rail dynamic contact forces and generates a high level of noise, which is a nuisance...doctoral thesis 2022

Zhang, Shizhe (author)Alkali-activated Materials (AAMs), including those classified as geopolymer, are obtained through the reaction between a solid precursor and an alkaline solution. Compared with ordinary Portland cement (OPC) binders, these materials maintain comparable mechanical properties but have the advantage of reducing greenhouse gas emissions and...doctoral thesis 2022

Zhang, D. (author)For exploration and development of the earth, seismic surveys are acquired to provide information about the subsurface, within specifications of accuracy set by geologists and engineers, and within business constraints on budgets and turn-around time for processing and interpretation of the data. The case of seismic surveys that are acquired,...doctoral thesis 2022

Zhang, T. (author)Fine-grained emotion recognition is the process of automatically identifying the emotions of users at a fine granularity level, typically in the time intervals of 0.5s to 4s according to the expected duration of emotions. Previous work mainly focused on developing algorithms to recognize only one emotion for a video based on the user feedback...doctoral thesis 2022

Zhang, F. (author)Existing concrete bridges require efficient assessment due to increasing traffic load and degrading material. For reinforced concrete structures without shear reinforcement, a typical failure mode is shear, which often means a total loss of structural capacity and does not have an obvious warning beforehand. To indicate the shear failure before...doctoral thesis 2022

Zhang, F. (author)Solid‐state caloric effects as intrinsic responses from different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐ and electronic‐ fields) have been evaluated near magnetic phase transformations. In the last decades the magnetically driven caloric changes in various magnetocaloric materials (MCMs) have been exploited extensively...doctoral thesis 2022

Zhang, H. (author)With the attempt to reduce traffic noise, porous asphalt (PA) mixture is widely used as a wearing course on the highways in the Netherlands. However, due to the open structure, PA mix pavement easily suffers from the loss of individual aggregates from its surface, which is named as ravelling. After the initial ravelling, the damage can rapidly...doctoral thesis 2022

Zhang, J. (author)Cracks, which could nucleate and propagate in engineering structures, could have an adverse effect on mechanical performance and even lead to catastrophic failure. Thus, it is critical to investigate structural behavior under fracture, which requires an appropriate modeling methodology for fracture analysis. Furthermore, designing structures...doctoral thesis 2022

Zhang, Y. (author)Structure-conserving numerical methods that aim at preserving certain structures of the PDEs at the discrete level have been an interesting research topic for many decades. The mimetic spectral element method, a recently developed arbitrary order structure-preserving method on orthogonal or curvilinear meshes, has also been drawing increasingly...doctoral thesis 2022

Zhang, Y. (author)Multi-stable beam-type metastructures exhibiting snap-through behavior have been extensively studied in recent years , as their stable states can be maintained without the need of external power supply. By arranging a series of beams exhibiting bi-stability, multi-stable metastructures can be constructed. However, current designs of multi-stable...doctoral thesis 2022
