Robust Computing Systems: From Today to the N3XT 1,000×
08 May 2019 | | Contributor(s):: Subhasish Mitra
This talk presents an overview of my group’s research in the above areas, and particularly emphasizes complexity and performance.
04 Jun 2018 | | Contributor(s):: Xingshu Sun, Raghu Vamsi Krishna Chavali, Muhammad Ashraful Alam
This package contains the Matlab scripts to perform the Suns-Vmp method. The code has been tested in Matlab R2016a.
Too hot to handle? The emerging challenge of reliability/variability in self-heated FintFET, ETSOI, and GAA-FET
11 Jan 2016 | | Contributor(s):: Muhammad A. Alam, Sang Hoon Shin, Muhammad Abdul Wahab, Jiangjiang Gu, Jingyun Zhang, Peide "Peter" Ye
This presentation is part of the 8th IEEE/ACM Workshop on Variability Modeling and Characterization (VMC) 2015. It is difficult to control the geometry, doping, and thicknesses of small transistors. Moreover, nanoscale transistors degrade due to NBTI and HCI at vastly different...
Failures in Photovoltaic Modules
21 Apr 2015 | | Contributor(s):: Peter Bermel
In this talk, I will discuss some of the major sources of performance degradation for common glass-encapsulated PV modules, including crystalline silicon and thin films. The greatest reliability challenges have occurred in the latter, with recent studies showing that thin-film modules operating...
