User/environmental context detection on mobile devices benefits end-users by providing information support to various kinds of applications. A pervasive question, however, is how the sensors on the mobile device should be sampled energy efficiently without sacrificing too much detection accuracy. In this paper, we formulate the user state sensing problem as the intermittent sampling of a semi-Markov...
As transistor sizes decrease, transient faults are becoming a significant concern for processor designers. A rich body of research has focused on ways to estimate the vulnerability of systems to transient errors and on techniques to reduce their sensitivity to soft errors. In this research, we analyze how compiler optimizations impact the expected number of failures during the execution of an application...
