  2. Deterrence theory - Wikipedia

    en.wikipedia.org/wiki/Deterrence_theory

    Deterrence theory holds that nuclear weapons are intended to deter other states from attacking with their nuclear weapons, through the promise of retaliation and possibly mutually assured destruction. Nuclear deterrence can also be applied to an attack by conventional forces.

  3. Defence in depth - Wikipedia

    en.wikipedia.org/wiki/Defence_in_depth

    Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack ...

  4. Delay, Deny, Defend - Wikipedia

    en.wikipedia.org/wiki/Delay,_Deny,_Defend

    Delay, Deny, Defend is a critical exploration of the property and casualty insurance industry, examining how its practices affect policyholders.Feinman, a law professor specializing in consumer rights and insurance law, argues that the industry prioritizes profits over policyholders' needs, often using tactics like delaying or denying legitimate claims to bolster financial performance.

  5. Change detection - Wikipedia

    en.wikipedia.org/wiki/Change_detection

    In statistical analysis, change detection or change point detection tries to identify times when the probability distribution of a stochastic process or time series changes. In general the problem concerns both detecting whether or not a change has occurred, or whether several changes might have occurred, and identifying the times of any such ...

  6. Proactive cyber defence - Wikipedia

    en.wikipedia.org/wiki/Proactive_cyber_defence

    Proactive cyber defense, means acting in anticipation to oppose an attack through cyber and cognitive domains. [1] Proactive cyber defense can be understood as options between offensive and defensive measures. It includes interdicting, disrupting or deterring an attack or a threat's preparation to attack, either pre-emptively or in self-defence.

  7. Delay differential equation - Wikipedia

    en.wikipedia.org/wiki/Delay_differential_equation

    DDEs are also called time-delay systems, systems with aftereffect or dead-time, hereditary systems, equations with deviating argument, or differential-difference equations. They belong to the class of systems with the functional state , i.e. partial differential equations (PDEs) which are infinite dimensional, as opposed to ordinary ...

  8. Delay reduction hypothesis - Wikipedia

    en.wikipedia.org/wiki/Delay_reduction_hypothesis

    The hypothesis was originally formulated to describe choice behaviour among concurrently available chained schedules of reinforcement; [2] however, the basic principle of delay reduction () as the basis for determining a stimulus’ conditionally reinforcing function can be applied more generally to other research areas.

  9. Ambiguity function - Wikipedia

    en.wikipedia.org/wiki/Ambiguity_function

    In pulsed radar and sonar signal processing, an ambiguity function is a two-dimensional function of propagation delay and Doppler frequency, (,).It represents the distortion of a returned pulse due to the receiver matched filter [1] (commonly, but not exclusively, used in pulse compression radar) of the return from a moving target.
