Professor emeritus Arne Ljungqvist from Karolinska Institutet, Stockholm, who has served in various high positions in the IOC, International Association of Athletics Federations (IAAF), Swedish Sports Confederation, to mention some of them, has dedicated a great deal of his life to service in sports and sports medicine. Arne Ljungqvist has especially dedicated his career to the fight against do...

Following paper shows the result of the development mobile robot ATRVJr for Fire Fighter Services dedicated to the risky intervention tasks. The concept of the hybrid software architecture based on Player and CORBA is shown. The basic functionalities such as SLAM, autonomous navigation and 3D map building are described. The HMI equipped with 3D visualization module is demonstrated. The experime...

Previous research indicates that pilots of most jet-fighter aircraft attend to similar elements of the natural flight environment when flying at low altitudes. However, some evidence suggests that differences may exist for pilots of certain specific types of aircraft. The present experiment examined the influence of operational factors on the perceived structure of real-world scenes viewed duri...

Abstract High performance aircraft of the future will be designed lighter, more maneuverable, and operate over an ever expanding flight envelope. One of the largest differences from the flight control perspective between current and future advanced aircraft is elasticity. Over the last decade, dynamic inversion methodology has gained considerable popularity in application to highly maneuverable...

Non-radicular neck pain arising from local musculoskeletal structures, known as mechanical neck pain or somatic dysfunction, is highly prevalent in the fighter jet aviator population. The management of this problem includes both therapeutic and aeromedical decisions. In addition to non-steroidal anti-inflammatory medications, waiver guides recommend therapeutic exercise and manipulative therapy...

Military fighter pilots have to function in environments that unavoidably have an effect on both production and reception of speech. Speech production is affected by for example g-forces, positive pressure breathing (PBG), background noise and workload. This can have an effect on the understandability of speech, which in turn can affect flight safety. This study seeks to analyse the changes in ...

Transonic and supersonic flows over isolated wings and fighter-type aircraft configurations are computed through the numerical solution of the compressible Euler equations. Appropriate singlemesh topologies are used in combination with a new multigrid time-stepping scheme for solving the Euler equations. C-H or C-0 meshes are used for the isolated wing. A novel H-0 type mesh is introduced to di...
