A time history algorithm for aircraft noise

Optimum Design of Scallop Domes for Dynamic Time History Loading by Harmony Search-Firefly Algorithm

This paper presents an efficient meta-heuristic algorithm for optimization of double-layer scallop domes subjected to earthquake loading. The optimization is performed by a combination of harmony search (HS) and firefly algorithm (FA). This new algorithm is called harmony search firefly algorithm (HSFA). The optimization task is achieved by taking into account geometrical and material nonlinear...

A new method for aircraft noise synthesis

This paper presents a method to synthesize aircraft noise. The method provides designers with a tool for sound quality evaluation with which target sounds for future aircraft design can be developed. Quick and economic evaluations concerning the quality of sounds of different design alternatives or improvements on existing aircraft become possible. The method has the potential to become a cruci...

Development of a Genetic Algorithm for Advertising Time Allocation Problems

Commercial advertising is the main source of income for TV channels and allocation of advertising time slots for maximizing broadcasting revenues is the major problem faced by TV channel planners. In this paper, the problem of scheduling advertisements on prime-time of a TV channel is considered. The problem is formulated as a multi-unit combinatorial auction based mathematical model. This is a...

Algorithm Development for a Real-Time Military Noise Monitor

Requirements for the protection against aircraft noise.

In preparation of the revised edition of the Air Traffic Noise Act the Federal Environmental Agency formulated targets for aircraft noise control. They were prepared oriented to the Federal Immission Control Act. The assessment periods were chosen analogously to the regulations on other traffic noise sources (rail traffic, road traffic). The control targets cover the following affected areas * ...
