In this paper, an approach to aeronautical structural design based on reliability analysis is presented. In this way, the concept of level of safety is discussed and methods of its calculation using statistical data are described. Based on the concept of level of safety, a design procedure is proposed. In order to validate this design procedure, two design cases are studied. In the first case s...

The previous two projects jointly conducted by the same team, AVT/T-121 Application of Smart Materials in the Vibration Control of Aeronautical Structures (April 2000March 2002) and AVT/T-129 Development of Control Strategies for the Vibration Control of Smart Aeronautical Structures (April 2002March 2004), form the basis of this project. During these, first the smart beam-like structures were ...

We use relational pointer machines as a framework for generalized computational complexity. Non-reuse of memory space, dubbed monotonic computing, is proposed as a fundamental concept that threads together various abstract generalizations of PTime. Depending on the use of space, relational machines generalize DLogSpace, PTime, NPTime and PSpace, We show that alternating first order machines are...

Secondary spectrum access emerges as a means to increase spectrum utilization significantly in a near future. However, the technical availability and the economic value of the secondary access have not been fully investigated. Particularly, the impact of the secondary access on the real-life primary systems remains mostly unaddressed. Among the primary systems of interest are aeronautical commu...
