Directional impedance of geared transmissions
… impedance, a characteristic of geared transmissions in which the amount of power loss through the transmission differs according to the direction of power flow. Typical robots use electric motors with high gear reduction which introduces larger impedance when power flows from the output …

Study of basin scale acoustic transmissions
A basin-scale acoustic tomography experiment was conducted in the northeast Pacific from May 1987 to September 1987. In this thesis, the stability of the forward model is analyzed. There are large non-linearities in the changes in travel time between ray paths for the four seasons . I constructed a …

Design of high performance hybrid transmissions
This thesis explores the design, development, and evaluation of transmission systems for integration into high-performance hybrid (internal combustion engine (ICE) and electric motor) vehicles. Traditional hybrid vehicle designs often fall into one of two categories. Every day road vehicles …

Feasibility study of hydrostatic transmissions for automobile applications
The feasibility of obtaining improved fuel efficiency by incorporating a hydrostatic transmission was investigated. The proposed transmission was composed of positive-displacement axial-piston hydraulic devices. The displacement of the pump and motor units could be varied to allow the prime mover …

Horizontal directional spectrum estimation of the Heard Island transmissions
… determine the spatial structure of the received transmissions. In this thesis, data from the Canadian Defense Research Establishment Pacific horizontal line array is used to form an estimate of the directional power spectrum. This spectrum determines if any horizontal multipath is detectable. The …

Comparative design, modeling, and control analysis of robotic transmissions
… the overall system performance. The different transmissions are tested for system nonidealities and generalizations drawn on the stability and performance margins of impedance and torque-servoed geared, cycloidal, planetary, and cable reducers in hard contact with the environment. Experimental …

Implementation of Microwave Transmissions for Rocket Exhaust Plume Diagnostics
<p>Rocket-launched vehicles produce a trail of exhaust that contains ions, free electrons, and soot. The exhaust plume increases the effective conductor length of the rocket. A conductor in the presence of an electric field (e.g. near the electric charge stored within a cloud) can channel an …

Computational Analysis and Network-based Modeling of Cross-Species Transmissions
Zoonotic spillover of pathogens is the dominant cause of emerging infectious diseases.Cross-species transmission (CST) risks are accelerated by climate change, which alters animal habitats and aggregates new combinations of host species at high population density and elevations. Modeling CST …

Scheduling wireless transmissions exploiting application awareness and knowledge of the future
… ways to improve the scheduling of wireless transmissions, by exploiting the application layer information of the ongoing transmissions and exploiting the knowledge of the future capacity variations. First, we consider the design of cross-layer opportunistic transport protocols for stored …

Transmissions of Hashed Personally Identifiable Information to Third Parties Across Websites
… Haw, a browser extension that detects and logs transmissions of hashed PII. Employing this tool, we conduct a field study with over 100 participants and observe widespread sharing of hashed PII—including email addresses, phone numbers, and demographic information—from hundreds of websites to …

Error Concealment for Robust Image and Video Transmissions on the Internet
… packet loss are two primary concerns for image transmissions. Existing approaches for delivering single-description coded images by TCP give superior quality but very long delays when the network is unreliable. To reduce delays, we have proposed to use UDP to deliver sender-receiver based …

Characterization of Electron Number Density of Rocket Exhaust Plumes Through Microwave Transmissions
<p>Charged rocket plumes generally exceed the length of their source vehicles, and offer lightning a favorable path to ground. Rocket plumes enhance the induced transient currents in flight electronics, and increase the risk of vehicle failure. The affinity of lightning to the plume can be …

Synchroniser analysis and shift dynamics of powertrains equipped with dual clutch transmissions
Transient dynamic investigations of dual clutch transmission equipped powertrains are conducted in this thesis through the development and application of torsional multi-body models incorporating multiple nonlinearities. Shift control studies are performed using detailed hydraulic model integrated …
