Automated discovery of performance regressions in enterprise applications
(2011-01-31)Performance regression refers to the phenomena where the application performance degrades compared to prior releases. Performance regressions are unwanted side-effects caused by changes to application or its execution ... -
Automatic Magnetometer Calibration with Small Space Coverage
(2013-05-01)The use of a standalone Global Navigation Satellite System (GNSS) has proved to be insufficient when navigating indoors or in urban canyons due to multipath or obstruction. Recent technological advances in low cost ... -
Axis Mapping: The Estimation of Surface Orientations and its Applications in Vehicle Localization and Structural Geology
(2016-10-01)The map representation of an environment should be selected based on its intended application. For example, a geometrically accurate map describing the Euclidean space of an environment is not necessarily the best choice ... -
Bayesian Detection of a Change in a Random Sequence with Unknown Initial and Final Distributions
Quickest detection is a class of detection problems whereby the objective is to identify a change in distribution of an observed sequence of random variables as quickly as possible. Quickest detection has been applied to ... -
Belief Propagation Decoding of Finite-Length Polar Codes
(2012-02-01)Polar codes, recently invented by Arikan, are the first class of codes known to achieve the symmetric capacity for a large class of channels. The symmetric capacity is the highest achievable rate subject to using the binary ... -
