In summer 2000, the Clinton administration is scheduled to decide whether to authorize deployment by the United States of a limited national missile defense (NMD) system. This date arose from a “3+3” policy announced in the midst of the 1996 election campaign: under it, the administration would conduct research and development on missile defenses until 2000, then decide whether to proceed to a ...

background : burn wounds are one of the health problems in modern societies that are associated with irreparable harms and many side problems for patients and their families. infection due to burn wounds is the main cause of death in such patients. one of the methods to prevent infection of burn wounds is topical antibiotic ointments. this study aimed to investigate and identify effective ointm...

A new approach to guiding a swarm of missiles using an on-line evolutionary algorithm to optimise the flight paths is introduced. The missiles are flown via intermediate points which are adjusted dynamically by the evolutionary algorithm, then towards the point of impact with the target, thus altering the trajectory shape. Evolutionary algorithms are robust global optimisation techniques and ar...

In this paper the communication mechanisms of a missile engagement simulator are modelled and analysed. The simulator is developed as a testing platform for missile guidance and control algorithms. The simulation uses concurrency and remote execution concepts to enhance performance. Coloured Petri nets are a well suited formal approach for modelling and analysis of these concepts. Design/CPN is...

The TENA SDA has developed and validated a common architecture called TENA, which provides for real-time software system interoperability using the TENA Middleware, as well as interfaces to existing range assets, C4ISR systems, and simulations. The TENA Middleware, currently at Release 6.0.3, has been used by the range community for testing, evaluation, and feedback in many major exercises sinc...

This paper shows a method to obtain the exact solution for a missile and an aircraft differential games which minimizes and maximizes the essential pay-off of the problem: the miss distance, without employing any linearized approximation. For this purpose, we introduced the concept of energy maneuverability. Once the families of optimal terminal surfaces are obtained, the proposed method can so...

Based on previous work, a Nussbaum gian controller is proposed to solve the unknown input direction problem of a large family of supersonic missiles. Also considering the one order dynamic characteristic of actuator , the uncertainties of nonlinear missile system, which is assumed to satisfy the socalled bounded uncertainty condition, are coped by the adopting of integral action and backsteppin...

Naval warfare is shifting from an almost exclusive deep water, open ocean engagement to a littoral environment where high-value surface ships are forced to operate in close proximity to land, exposing those ships to a new, significant threat the high speed, sea skimming missile launched from coastal defenses, mobile land launchers, and patrol craft and maritime aircraft operating close to shore...

A new algorithm, advantage learning, is presented that improves on advantage updating by requiring that a single function be learned rather than two. Furthermore, advantage learning requires only a single type of update, the learning update, while advantage updating requires two different types of updates, a learning update and a normilization update. The reinforcement learning system uses the ...
