Mobile computer users often have a false sense of anonymity when they connect to the Internet at cafes, hotels, airports or other public places. In this paper, we analyze information leaked by mobile computers to the local access link when they are outside their home domain.

Chattering arcs and chattering controls
Journal of Optimization Theory and Applications, 1973There are two different meanings of the wordchattering in control theory and optimization theory. Chattering arcs of the first kind are related to the notion of relaxation of the control (i.e., convexization of the maneuverability domain). Some sufficient conditions of equivalence of these notions are defined.

Approximate solutions for chattering control and chattering arc
Acta Astronautica, 2000Abstract The approximate solution for chattering arc of the first kind chattering control has been studied. Both symmetrical and asymmetrical cases are considered. A practical example analyzed in this paper is the maximum drag reentry flight of a winged space vehicle in the vertical plane. The control variable is the normalized lift coefficient (NLC),

Comparison of classifiers for chatter detection
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013Unstable machine cutting causes chatter and reduces quality of the production. Therefore it must be detected. Several techniques have been presented for this reason. The aim of this study is to determine the data, features and classifiers which fit on chatter detection.

An averaging approach to chattering
IEEE Transactions on Automatic Control, 2001Sliding mode control systems with fast actuators are modeled as singularly perturbed relay control systems. Sufficient conditions for stability of fast periodic solutions to the singularly perturbed system are found. The corresponding averaged equations are introduced.
