ZxOS: Zephyr-based Guest Operating System for Heterogeneous ISA Machines
… ZxOS, is built by modifying the open-source ZephyrOS, including its architecture-specific code and page mapping mechanism to create a memory region that can be shared across heterogeneous- ISA CPUs. Since existent heterogeneous-ISA hardware has physically discrete memory for ISA-heterogeneous …

Zephyr: a Data-Centric Framework for Predictive Maintenance of Wind Turbines
… and costly. In this thesis, we present Zephyr, a flexible machine learning framework for predictive maintenance of wind energy assets. Manual analysis of wind turbine data is difficult and time-consuming due to its volume, variety, and, most importantly, the need for quick detection of …

Effectiveness of a non-penetrating captive bolt for euthanasia of suckling and weaned piglets
… effectiveness of a non-penetrating captive bolt (Zephyr-E) for euthanasia of piglets ≤ 9 kg. Brainstem and spinal reflexes and heartbeat were used to determine the time to insensibility and death. Post-mortem damage was scored to assess the degree of traumatic brain injury (TBI) induced by the …

Implementation of network moving target defense in embedded systems
… a network shuffling proof of concept in the Zephyr real time operating system to tackle the challenge of incorporating shuffling techniques into embedded systems. A host-centric, high security implementation is provided which maximizes attacker uncertainty and minimizes the impact of host …

Adapting Kerberos for a browser-based environment
… we present Roost, a Web-based client for the Zephyr messaging and notification in use at MIT, along with a host of proof-of-concept applications. We find that it is possible to build Web-based clients for Kerberized services similar to or better than existing native ones with no modifications …

Quantifying changes in accelerations and heart rate indicative of fatigue during condensed competitions in elite youth ice hockey players
… youth ice hockey players wore Bioharness-3 (Zephyr, MD) sensors to compare accelerations (ACC) and heart rate (HR) over four games (G1–G4) in three days, in order to establish changes in cardiovascular stress and physical exertion associated with fatigue. Peak ACC and HR across multiple time …

The Astrometric Contribution of Unresolved Stellar Companions
No astronomical body is alone - some fraction of the mass of a system will always be found in orbiting bodies, ranging from fragmented debris to planets, stars and compact objects. In general we ‘see’ the brighter component: one star often dominates the detectable light, obscuring the companion - …

Asynchronous differential power processing for true maximum power point tracking of photovoltaic sub-modules
This thesis examines maximum power point tracking (MPPT) at the photovoltaic (PV) sub-module level, but in the context of large arrays. Central communication carries large overheads, and neighbor-to-neighbor communication can have long propagation times in large arrays, so a communication-less …
