Simulated Annealing (SA) is used to solve various combinatorial optimisation problems and local search problems. This paper deals with Cooperative Target Observation (CTO) by groups of Unmanned Aerial Vehicles (UAV). We propose a Modified SA algorithm for optimising the position of each of the UAVs to observe the maximum number of targets. CTO is a very good example of study of multi agent cooperation. We compare with Hill Climbing algorithm and Modified SA algorithm and find that the Modified SA algorithm is superior for almost all target speeds, UAV sensor ranges and various group sizes.

A hierarchical cognitive robotics model for a team of unattended robotic ground vehicles (UGVs) is proposed. The first level rigorously defines conflict resolution for a couple of UGVs, using dynamical games on SE(2)-groups of plane motion. The second level extends it to n UGVs, using Nash-equilibrium approach. The third provides adaptive guidance for several groups of UGVs. The fourth, collective manoeuvre level, proposes a combination of an attractor neural model and a fuzzy-neural 'supervisor', to perform an adaptive path definition and waypoints selection, as well as chaos control. The fifth, cognitive level, performs overall mission planning/feedback control.

A generalised reaction-diffusion field model for robot navigation is proposed. It utilises two mutually antagonistic neural fields counteracting in patterns similar to that of flexor/extensor muscles controlling the movements in major joints in the human body. Combining local activation and generalised inhibition represented by Amari's neural field equations and extended by the Fitzhugh-Nagumo and Wilson-Cowan activator-inhibitor systems, results in the type of neural attractor dynamics that may lead to spontaneous oscillatory pattern formation. Preliminary simulation data suggest that this approach has utility in enabling a team of autonomous vehicles to navigate in a crowded pedestrian crossing.

A 'design archetype' is a characterisation of the possible designs that a given system design approach can generate. The central concern is the need for flexible and structurally scalable design approaches. The design archetype is a pattern for generating system designs of arbitrary scale; design approaches cannot not scale well that do not sufficiently limit the range of designs they can produce. The Kolmogorov and uniform complexities of the design archetype are used to quantify the scalability of its corresponding design methodology; system design approaches are classed according to the upper bounds on these measures as the system size increases.

The intelligent agent paradigm has shown considerable promise as a candidate for general complex systems development. However, it is our belief that this promise will remain unfulfilled, with application of the paradigm constrained to situations where there is an overriding requirement to model human behaviour in a cognitively realistic manner. In our experience, such applications are uncommon and we have found that a team programming paradigm, as realised in frameworks such as GORITE, is generally more appropriate for complex systems development, particularly for engineered systems. In this paper, we introduce both the team programming paradigm and its realisation using GORITE.

This paper presents a capabilities-based representation that provides a single picture of future military capability for the UK. The visual representation allows the different service branches of the armed forces to both explore and determine their degree of commonality and inter-service capabilities. To achieve this, a framework was developed to provide an architecture for visually representing strategic military capability. The framework is composed from three layers which combine effects-based operations, force structures and the building blocks (facilities and platforms). This framework was then populated with data from the UK's Ministry of Defence, British Army, Royal Navy and Royal Air Force.

GPS provides an accurate position and velocity information but with a slower update rate, whereas INS provides position, velocity and attitude information with a higher update rate. However, INS alone cannot provide proper solutions due to the increasing error characteristics of the accelerometer and gyros of the inertial sensor. To get an accurate navigation solution, it is necessary to integrate INS with GPS. This paper discusses integration of INS/GPS systems using Extended Kalman Filter (EKF). TMS320vc33 floating point DSP is used for INS and EKF computations. A FPGA (Field Programmable Gate Array) based GPS data acquisition system and Dual Port RAM (DPRAM) have been designed and used for the presented architecture.

Advances in technologies such as computing, sensors, sensor processing, and data fusion techniques mean that intelligent decision-making technologies (IDT) will soon have the capacity to control weapons in a manner that includes decisions regarding target identification and engagement. If permitted, this would provide these systems with the ability to decide which targets to prosecute with lethal force, without any operator intervention. This would mark a sea-change in the role of technology in warfare as the human can be removed from the decision-making loop. There are complex technological and legal issues regarding the development, deployment and exploitation of such systems.

This paper presents a new methodology, based on the probabilistic approach, for biorhythmic analysis to prevent aviation accidents. The methodology has been developed using the Gaussian distribution technique for reliability evaluation of the aviation system, keeping in mind the biorhythmic effects of the pilot. The normal distributed data of the US Air Force were tested and analysed based on the performance ability of pilot and the peak demand of the performance. The accident zone is that area of operation during which the performance demand exceeds the performance ability of the aircraft pilot. Failure probabilities, considering peak performance demand and the pilot's ability, have been evaluated using the Gaussian distribution approach. The safety factor concept has also been presented in this paper for biorhythmic analysis to prevent aviation accidents. The stepped incident-duration curve has been utilised to evaluate the pilot's reliability on the aviation system using Simpson's 1/3rd rule.
