Bifurcations, Multi-stability, and Localization in Thin Structures
… This dissertation studies snap-through, multi-stability, and localization in thin rods and sheets through a combination of experiments and numerics. The first work experimentally explores the multi-stability and bifurcations of buckled elastic strips subject to clamping and lateral end …

Transitions-felt: William James, Locative Narrative and the Multi-stable Field of Expanded Narrative
… Extending the cognitive term ‘perceptual multistability’, that refers to switching between interpretations experienced when we look at an ambiguous figures, such as, the Necker cube, this thesis develops the position that expanded narrative practices and specifically locative narrative, a …

Nonlinear thermoacoustic oscillations of a ducted laminar premixed flame
Finding limit cycles and their stability is one of the central problems of nonlinear thermoacoustics. However, a limit cycle is not the only type of self-excited oscillation in a nonlinear system. Nonlinear systems can have quasi-periodic and chaotic oscillations. This thesis examines the different …

Commonalities And Differences In Visual And Auditory Multistability
Perceptual bi/multi-stability—the phenomenon in which perceptual awareness switches between alternative interpretations of a stimulus—can be elicited by a large range of stimuli. The phenomenon is explored in vision, audition, touch, and even olfaction. The degree to which perceptual switching …

A framework for understanding heterogeneous differentiation of CD4⁺ T cells
… the master regulators govern the formation of multi-stability behavior, which in turn gives rise to heterogeneous differentiation. The framework can be applied to systems with two or more master regulators, and models based on the framework can make specific predictions about heterogeneous …

Multi-stable Compliant Rolling-contact Elements
… concepts and models of large-angle, compliant, multistable, revolute joints. This research presents evidence of the capability of these models and concepts by presenting a case study in which the miniaturization of revolute joints are examined. Previous attempts at multistable revolute joints …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
… Another challenge in designing LEMs is creating multi-stable mechanisms with the ability to have coplanar links. A method is presented for offsetting the joint axes of a spatial compliant mechanism to introduce multi-stability. A new bistable spatial compliant linkage that uses that technique is …

Dynamics of a Q-switched all-fibre laser
… Additionally, we report observed hysteresis and multi-stable dynamics for a range of absorber lengths for which the laser evolves along two different operational paths during up-scans and down-scans over ranges of the input pump. This bistable region is close to the switch between the two …

Testing alternative stable state theory at Afromontane and Milkwood forest-fynbos ecotones
… modifications to disturbance regimes alter the stability of forests and fynbos and may shift forest and fynbos into a degraded species-poor state. Conservation practitioners are concerned over perceived loss of forest habitat, and tree planting initiatives are common in parts of the Western Cape …

Optical properties and thermal conductivity of resistive Au nanogranular films
… At room temperature and atmospheric pressure, stability and reproducibility of the resistance switching of such nanogranular Au films was observed to last over many hours thus making them ideal test beds for exploration of the basic mechanisms of the switching processes and allow convenient …
