Introduction Vestibular and visual information is used in determining spatial orientation. Existing computational models of orientation perception focus on the integration of visual and vestibular orientation information when both are available. It is well-known, and computational models capture, differences in spatial orientation perception with v...

Background Stochastic resonance (SR) is achieved when a faint signal is improved with the addition of the appropriate amount of white noise. Perceptual thresholds are expected to follow a characteristic performance improvement curve as a function of the white noise level added (i.e., thresholds are reduced with an optimal amount of added white nois...

Background Stochastic resonance (SR) refers to a faint signal being enhanced with the addition of white noise. Previous studies have found that vestibular perceptual thresholds are lowered with noisy galvanic vestibular stimulation (i.e., “in-channel” SR). Auditory white noise has been shown to improve tactile and visual thresholds, suggesting “cro...

Astronauts on future deep space exploration missions will need to maintain excellent performance to ensure safety and mission success. To enhance neurocognitive and task performance, stochastic resonance (SR) may be used to enhance "information transfer" to the brain across multiple sensory modalities, reducing the cognitive workload associated wit...

Crewed deep space missions will increasingly rely on collaborations between astronauts and autonomous systems. Autonomous intelligent systems on board the spacecraft may perform some tasks traditionally done by ground control (e.g., planning, information transfer, decision support) without any communication delays. The human crew should be able to...

This thesis examines the application of vestibular white noise as a non-pharmaceutical method of performance enhancement. Vestibular white noise refers to low levels of electrical noise applied by skin mounted electrodes to the mastoids. Applied this way, the electrodes are able to stimulate the vestibular afferents. The overarching project seeks t...

Optimized for millions of years, natural materials often outperform synthetic materials due to their hierarchical structure and multi-functional abilities. They usually feature a complex architecture that, however, consists of simple building blocks. Indeed, many natural materials such as bone, nacre, hair and spider silk, have outstanding material...

Every year millions of people are displaced due to natural disasters and very primitive transitional shelters, or 't-shelters', exist to provide semi-permanent housing. Many t-shelter designs do not cater to all the needs of their inhabitants and are only functional in the short term, often leaving many people relying on t-shelters for housing in a...
