Ownship Strategies during Hostile Torpedo Attack

Particle Filter Based Ownship Evasive Maneuver under Torpedo Attack

Particle filter is proposed for tracking a torpedo using bearings-only measurements when torpedo is attacking an ownship. Towed array is used to generate torpedo bearing measurements. Ownship evasive maneuver is used for observability of the bearings-only process. Particle filter combined with Modified Gain Bearings-Only Extended Kalman Filter is used to estimate torpedo motion parameters, whic...

Evolutionary Design of Attack Strategies

We propose and investigate a new concept for automatic search for attack strategies and demonstrate its use in the area of wireless sensor networks. We exploit mechanisms inspired by the biological evolution, known as Evolutionary Algorithms and we use a combination of simulation (or real system execution) with a candidate attacks generator. Each candidate is evaluated, its success is measured ...

Survival in hostile environments: strategies of renal medullary cells.

Cells in the renal medulla exist in a hostile milieu characterized by wide variations in extracellular solute concentrations, low oxygen tensions, and abundant reactive oxygen species. This article reviews the strategies adopted by these cells to allow them to survive and fulfill their functions under these extreme conditions.
