Analysis of flip ambiguities for robust sensor network localization
 Vehicular Technology, IEEE Transactions on
"... Abstract—Erroneous local geometric realizations in some parts of a network due to the sensitivity to certain distancemeasurement errors with respect to some neighboring sensor locations is a major problem in wireless sensornetwork localization, which may, in turn, affect the reliability of the lo ..."

of the localization of the whole or a major portion of the sensor network. This phenomenon is well described using the notion of “flip ambiguity ” in rigid graph theory. In this paper, we present a formal geometric analysis of flipambiguity problems in planar sensor networks via quantification of the likelihood
1Tackling the Flip Ambiguity in Wireless Sensor Network Localization and Beyond
"... Abstract—There have been significant advances in rangebased numerical methods for sensor network localizations over the past decade. However, there remain a few challenges to be resolved to satisfaction. Those issues include, for example, the flip ambiguity, high level of noises in distance measure ..."

Robust Distributed Network Localization with Noisy Range Measurements
, 2004
"... This paper describes a distributed, lineartime algorithm for localizing sensor network nodes in the presence of range measurement noise and demonstrates the algorithm on a physical network. We introduce the probabilistic notion of robust quadrilaterals as a way to avoid flip ambiguities that otherw ..."

Reducing The Number Of Flips In Trilateration With Noisy Range Measurements
, 2013
"... Many applications in wireless networks depend on accurate localization services to operate properly. Trilateration is a widely used rangebased localization method that can operate in polynomial time, given that the distance measurements are precise. However in realworld, range measurements tend to ..."

to have errors due to internal and external factors. Flip ambiguities that occur during trilateration as a consequence of imprecise range measurements turn localization via trilateration into an intractable problem. In this paper, we analyze flip ambiguities due to range measurement errors and propose a
Defining Ambiguity and Ambiguity Attitude
"... According to the wellknown distinction attributed to Knight (1921), there are two kinds of uncertainty. The first, called “risk, ” corresponds to situations in which all events relevant to decision making are associated with obvious probability assignments (which every decision maker agrees to). Th ..."

). The second, called “(Knightian) uncertainty ” or (following Ellsberg (1961)) “ambiguity, ” corresponds to situations in which some events do not have an obvious, unanimously agreeable, probability assignment. As Chapter 1 makes clear, this collection focuses on the issues related to decision making under
AMBIGUITY AND AMBIGUITY AVERSION
, 2013
"... The phenomena of ambiguity and ambiguity aversion, introduced in Daniel Ellsberg’s seminal 1961 article, are ubiquitous in the realworld and violate both the key rationality axioms and classic models of choice under uncertainty. In particular, they violate the hypothesis that individuals ’ uncertai ..."

Kinematic Jump Processes For Monocular 3D Human Tracking
 In Int. Conf. Computer Vision & Pattern Recognition
, 2003
"... A major difficulty for 3D human body tracking from monocular image sequences is the near nonobservability of kinematic degrees of freedom that generate motion in depth. For known link (body segment) lengths, the strict nonobservabilities reduce to twofold ‘forwards/backwards flipping ’ ambiguities ..."

The charge flipping algorithm
, 2007
"... This paper summarizes the current state of charge flipping, a recently developed algorithm of ab initio structure determination. Its operation is based on the perturbation of large plateaus of low electron density but not directly on atomicity. Such a working principle radically differs from that of ..."
