Weak Signals in Information Security Management
2005Usually, information security management practices do not explicitly take account of weak signals, factors that lie below the detection surface, which may, however, constitute a huge security threat. This study analyses what kinds of weak signals are present in information security, followed by a discussion on their detection. Responses to weak signals

Television and Contraceptive Use – A Weak Signal?
The Journal of Development Studies, 2014AbstractIn recent years, rural electrification and access to television have spread throughout the developing world. The values and cultural norms embodied in television programming have potentially profound implications for influencing behaviour, including reproductive decisions.

Amplification and phase conjugation of weak signals
Soviet Physics Uspekhi, 1992The results of the study on phase conjugation of weak optical signals with the energy of units of photons are considered. Basic concepts of a semi-classical theoretical approach to describe amplification and phase conjugation (PC) of such signals are presented.

On Weak Signal Detection With Compressive Measurements
IEEE Signal Processing Letters, 2018The problem of weak signal detection in Gaussian noise is addressed in the Neyman–Pearson framework with compressive measurements. A locally optimum detector is first devised assuming that the signal is nonsparse by approximating the test statistic around zero using a Taylor series, which is a good estimate only in a small radius around zero.

The Scandinavian Journal of Economics, 2002
Akerlof, Spence and Stiglitz showed that competitive markets can perform very poorly in the presence of informational asymmetry. In this paper I show that if there is a signaling technology which is sufficiently strong (i.e., the marginal cost of signaling declines sufficiently rapidly with quality) the cost of sorting is low and a Nash equilibrium ...

Extraction of a weak climatic signal by an ecosystem
Nature, 2002The complexity of ecosystems can cause subtle and chaotic responses to changes in external forcing. Although ecosystems may not normally behave chaotically, sensitivity to external influences associated with nonlinearity can lead to amplification of climatic signals.

Tracking Bitcoin Users Activity Using Community Detection on a Network of Weak Signals
International Workshop on Complex Networks & Their Applications, 2017Bitcoin is a cryptocurrency attracting a lot of interest both from the general public and researchers. There is an ongoing debate on the question of users' anonymity: while the Bitcoin protocol has been designed to ensure that the activity of individual ...

Estimation and detection of weak optical signals
IEEE Transactions on Information Theory, 1972In this paper we consider the problem of estimation and detection of Weak optical signals formulated as a problem in point process theory. Indeed at very low light intensity the only information available from an intensity detector is the random distribution of time instants \{t_i \} at which photons of the field are absorbed and photoelectrons emitted.

Intermittent tracking in weak signal environments
2015 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2015Intermittent tracking or cyclic tracking is a common method used in modern Global Navigation Satellite System (GNSS) receivers to conserve power. It is critical for receivers in battery-operated devices like wearables, smartphones and handheld devices. These devices are often used in degraded or weak signal environments such as indoors.
