Influence of Bit Design on the Stability of the Rotary Drilling System
… and features of PDC bits, which consist of multiple fixed blades or cutters mounted on a bit body. It has been established that a state-dependent delay system can depict the mechanism of the stick-slip drillstring vibrations. The complex arrangement of cutters of a realistic PDC bit, …

Identifying barriers to accessing healthcare for chronic wounds in the Khayelitsha sub-district: a mixed methods study
… outcomes and increased healthcare costs. These delays are particularly pronounced within resource-constrained systems such as the South African public healthcare system. Identifying barriers to accessing care can contribute to developing interventions to optimise pathways to chronic wound care. …

Collaborative Autonomy of Multi-Agent Aerial Systems for Future Disaster Response
… under dynamic communication topologies with multiple delays and computes the maximum tolerated delay for reliable coordination. Building on this foundation, Chapter 4 proposes a distributed 3D cooperative path-planning framework for large-scale UAV swarms in cluttered environments. A hybrid …

Chaos and information in dynamic neural networks
… orbits to be stabilized. The addition of multiple delays changes the number and types of orbits that are available for stabilization. The use of synchronization between similar sets of chaotic systems may be used to target specific orbits.

Stability Analysis of Time Delay Systems Using Spectral Element Method
… techniques is motivated by the existence of delays in the governing equations of many physical systems such as turning and milling processes. </p><p>Delay differential equations appear in many models in science in engineering either as an intrinsic component (e.g. machining dynamics) or as a …

Optimising Signal Isolation and Phase Measurement in Digitally Enhanced Interferometry
… interferometry (DI) combines code division multiplexing with optical interferometry through the use of pseudo-random noise codes. It allows time-of-flight multiplexed precision sensing with interferometric sensitivity by using these codes to identify the signal of interest, while rejecting …
