Single Event Mitigation For Aurora Protocol Based Mgt Fpga Designs In Space Environments, Alexander Stanley Harding
Single Event Mitigation For Aurora Protocol Based Mgt Fpga Designs In Space Environments, Alexander Stanley Harding
Theses and Dissertations
This work has extended an existing Aurora protocol for high-speed serial I/O between FPGAs to provide greater fault recovery in the presence of high-energy radiation. To improve on the Aurora protocol, additional resets that affect larger portions of the system were used. Detection for additional error modes that occurred but were not detected by the Aurora protocol was designed. Radiation testing was performed on the Aurora protocol with the additional mitigation hardware. The test gathered large amounts of data on the various error modes of the Aurora protocol and how the additional mitigation circuitry affected the system. The test results …

A Reliability Prediction Method For Phase-Change Devices Using Optimized Pulse Conditions, Martin Jared Barclay
Boise State University Theses and Dissertations
Owing to the outstanding device characteristics of Phase-Change Random Access Memory (PCRAM) such as high scalability, high speed, good cycling endurance, and compatibility with conventional complementary metal-oxide-semiconductor (CMOS) processes, PCRAM has reached the point of volume production. However, due to the temperature dependent nature of the phase-change memory device material and the high electrical and thermal stresses applied during the programming operation, the standard methods of high-temperature (Temperature > 125 °C) accelerated retention testing may not be able to accurately predict bit sensing failures or determine slight pulse condition changes needed if the device were to be …
Electron – Phonon Interaction In Multiple Channel Gan Based Hfets: Heat Management Optimization, Romualdo A. Ferreyra
Electron – Phonon Interaction In Multiple Channel Gan Based Hfets: Heat Management Optimization, Romualdo A. Ferreyra
Theses and Dissertations
New power applications for managing increasingly higher power levels require that more heat be removed from the power transistor channel. Conventional treatments for heat dissipation do not take into account the conversion of excess electron energy into longitudinal optical (LO) phonons, whose associated heat is stored in the channel unless such LO phonons decay into longitudinal acoustic (LA) phonons via a Ridley path. A two dimensional electron gas (2DEG) density of ~5×1012cm-2 in the channel results in a strong plasmon–LO phonon coupling (resonance) and a minimum LO phonon lifetime is experimentally observed, implying fast heat removal from …
Competitive Unit Maintenance Scheduling In A Deregulated Environment Based On Preventing Market Power, Hessam Golmohamadi, Maryam Ramezani, Hamid Falaghi
Competitive Unit Maintenance Scheduling In A Deregulated Environment Based On Preventing Market Power, Hessam Golmohamadi, Maryam Ramezani, Hamid Falaghi
Turkish Journal of Electrical Engineering and Computer Sciences
With the advent of electricity markets, the traditional approach to unit maintenance scheduling (UMS) needs to undergo major changes in order to be compatible with competitive environment structures. The transition from a vertical power system to a competitive structure makes many challenges for policymakers and market designers. In this paper, a new approach to UMS in competitive electricity markets is presented. The main part of this study involves both how to treat generating companies (GENCOs) fairly and how to guarantee power system security during the maintenance scheduling. This paper advances the UMS in the electricity market so that one can …
