    The continual drive to optimise aerodynamic efficiency has resulted in commercial transport aircraft using increasing levels of relaxed longitudinal stability, which can result in dynamic instability and degradation in handling qualities. However, a carefully designed fly-by-wire flight control system can restore stability margins, shape the aircraft's response and optimise the handling qualities throughout its flight envelope. Advanced control law, rapid prototyping tools such as non-linear dynamic inversion (NDI), which are based on simple manipulations of the aircraft equations of motion, generate a perfect first-order response within control power constraints. In addition, NDI can be rapidly applied to any vehicle dynamic model for concept comparison, to quantify control power requirements and to provide a functional control law design. This article has applied NDI techniques to a longitudinally unstable second-generation supersonic transport aircraft on the landing approach to restore stability, to generate an ideal response and to provide desirable handling qualities.

    A million times more bandwidth; a billion people conducting global transactions through a trillion Internet-connected devices, a secure, reliable and self-managing computing infrastructure; unprecedented processing power for solving previously incalculable problems; new and profitable digital relationships. All are coming, and soon, What will they mean for enterprises, institutions and individuals? What will they do for content, communities and commerce? In the 21st century business environment, advanced technology will be integrated seamlessly into the core of every operation, both within the organisation and in its dealings with other enterprises. To succeed, constant technology innovation will need to be matched by an in-depth knowledge of industries and their challenges. View full abstract»

    Some of the accounts of information warfare carried by the media have been exaggerated or inaccurate, but this must not deflect us from addressing the crucial issues of defining, developing and deploying critical infrastructure protection policies and strategies. View full abstract»

    Robotic systems in surgical environments are becoming an increasingly common research area and a clinical reality. New standards and new results are expected from this branch of robotic applications, and revolutionary changes in the operating theatre are not too far away. This article describes the development of a new robot prototype, which combines the high reliability and safety of custom-designed electronics and controls with a new mechanical design delivering high-precision positioning and safe interaction with the surgical environment. The robotic system has been tested in vitro in laboratory simulations and has shown promising results during robot-assisted total knee replacement, thus indicating possible new surgical procedures in orthopaedic reconstruction.
