This paper investigates the possibility of signal jamming in games with multiple informed parties whose interests are conflicting. The possibility that signal jamming occurs in equilibrium depends on the observability of individual signals. Paradoxically, if the receiver can observe individual signals perfectly, signal jamming can occur in equilibrium, while it cannot occur if the receiver can observe only the one-dimensional signal synthesized from the senders' individual actions.

Energy Grid

The transformation of the traditional power grid into a cyber physical smart energy grid brings significant improvement in terms of reliability, performance, and manageability. Most importantly, existing communication infrastructures such as LTE represent the backbone of smart grid functionality. Consequently, connected smart grids inherit vulnerabilities associated with the networks including denial of service attack by means of synchronization signal jamming. This chapter presents cybersecurity in cyber-physical energy grid systems to mitigate synchronization signal jamming attacks in LTE based smart grid communications.

ABSTRACTAstronomy in all wavelengths is not the only science to suffer from various causes of pollution. Sites in which geophysical research is being conducted are also in danger due to a variety of external causes. Among them, the following are described and discussed in addition to electromagnetic nuisances that are common to geophysicists and astronomers: heat production, magnetic disturbances, artificial vibrations in seismic observatories, chemical pollution in atmospheric studies, signal jamming, vandalism and site modifications around automatic stations.

Pseudo-random code fuze has strong anti-interference ability. The paper studies about the jamming effectiveness of noise amplitude modulation operating on pseudo-random code fuze. Firstly the operating principle of pseudo-random code fuze is introduced. Then we analysis the characteristic of the noise amplitude modulation signal, following that is the study on the pseudo-random code fuze responses at all levels under noise amplitude modulation signal jamming. Studies have shown that the value of pseudo-random code fuze correlator output will decrease linearly as noise power increases when the power of noise amplitude modulation is low, but tends to be constant when the power of noise amplitude modulation arrives at a certain level. So under noise amplitude modulation jamming, higher jamming power doesnt show the best performance, but there is an optimal value of jamming power.

Governance Costs

ABSTRACT We develop an agency model in which managerial information manipulation creates pooling and entails ex post costs internal and/or external to the firm. We examine the implications of the strategic interactions between shareholders (who set internal governance and managerial incentive compensation), the manager (who exerts effort and reports on its outcome), and an external regulatory authority or RA (who investigates for fraud and levies penalties ex post). When the RA cannot pre-commit to an ex post investigation strategy, a fraudulent equilibrium obtains if the firm's internal governance costs are sufficiently high. Consistent with (so far fairly scant) post-SOX empirical evidence, but the opposite of the implications of signal-jamming models and equilibria with pre-commitment, the model implies an increase in minimum internal governance standards or ex post fraud penalties (as with SOX) results in decreased equilibrium pay-for-performance sensitivity and firm performance.
