Futures, 2012
This paper examines the concept of weak signals: its basic idea presented by Igor Ansoff and its later developments. We argue that recent futures studies have essentially deepened the analysis of this concept, which originally lacked an accurate definition.

On the detectability of weak signals
IEEE Trans. Inf. Theory, 2020Approximate performance results are obtained for optimal detection of weak discrete time signals. The analysis parallels the ''locally optimum'' approach for detector design and is based on a small-signal Taylor series approximation to the Chernoff error probability bounds.

Expert Systems with Applications, 2014
Abstract The weak signal concept according to Ansoff has the aim to advance strategic early warning. It enables to predict the appearance of events in advance that are relevant for an organization. An example is to predict the appearance of a new and relevant technology for a research organization.

Weak-signal iterative holography
Applied Optics, 2015An iterative holographic table-top experiment is presented, where a recorded hologram is used to re-illuminate the initial target. With this beam shaping setup, more light is directed to the target for each iteration until a convergence limit is met. We experimentally examine convergence properties of this iterative hologram reconstruction approach for

Powerful signals for weak muscles
Ageing Research Reviews, 2009The aim of the present review is to summarise, evaluate and critique the different mechanisms involved in anabolic growth of skeletal muscle and the catabolic processes involved in cancer cachexia and sarcopenia of ageing. This is highly relevant, since they represent targets for future promising clinical investigations.

GNSS signal acquisition in weak signal condition
2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP), 2014In this paper, a new method for Global Navigation Satellite System (GNSS) signal acquisition in weak signal condition is considered, mainly on bit transition and accumulation over multiple code periods. The impact of bit transition on the acquisition block is analyzed and an algorithm based on the Discrete Fourier Transform (DFT) operation is proposed ...

Progress in Research of Weak Signal
2011In this paper, the research progress of analysis of weak signals, an important area of signal analysis, is reviewed with respect of weak signals’ generation, identification and application. This paper goes over the main elements of domestic and foreign research advances, and points out the limitations of the research viewing angles and the description ...

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.
