    Publikacja

    - Rok 2003

    Civilisation generates many problems connected with job, which cannot be resolved by one field of science that deals with matters fragmentarily, only from its own point of view. Ergonomics, i.e. synthetic knowledge about job, can solve these problems by using the resources of many fields, e.g. physiology, psychology, technical science or economy. The achievements of these fields are used in ergonomics and thus problems connected...

  • Accelerated Parameter Tuning of Antenna Structures by Means of Response Features and Principal Directions

    Popularity of numerical optimization has been steadily on the rise in the design of modern antenna systems.
