Venkatasubramanian, Suresh | Sensor network localization for moving sensors | Sensor network localization (SNL) is the problem of determining the locations of the sensors given sparse and usually noisy inter-communication distances among them. In this work we propose an iterative algorithm named PLACEMENT to solve the SNL problem. This iterative algorithm requires an initial ... | | 2012-01-01 |

Macleod, Robert S. | Sensitivity of epicardial electrical markers to acute ischemia detection | Introduction: We hypothesize that electrocardiographic measurements from the intramyocardial space contain more sensitive markers of ischemia than those detectable on the epicardium. The goal of this study was to evaluate different electrical markers for their potential to detect the earliest phases... | | 2014-01-01 |
