Here we discuss a new integer multicommodity ow problem in which the commodities can not be shipped independently. The problem emerges in the routing of airplane parts from production sites to assembly sites. The parts are of such size that they have to be carried on dedicated trailers. Each type of part has its own type of trailer. A part is loaded on its trailer after it is produced, carried ...

Aircrafts are complex systems that require permanent and precise monitoring and troubleshooting. The automation of these tasks is thus of a high importance. This paper presents an intelligent decision system for faults diagnosis of aircrafts. The system relies on decision trees, being easier to interpret, quicker to learn than other data-driven methods, and able to work even with missing pieces...

The maintenance of military aircraft is complex and exhaustive, requiring an accurate training program. This process is not fault tolerant and requires certification renewal periodically. Furthermore, the process involves many professionals and resources, requiring phases of maintenance and verification of the tasks. Cooperation between professionals in the overall process is essential and requ...

The genetic programming approach is applied to the problem of aircraft autolanding, subject to wind disturbances. The derived control law is tested successfully, using a linearised model of a commercial aircraft. The evolutionary control of autolanding is done within the desired operational envelope.

In this paper an algorithm for the classification of aircrafts composing the commercial fleet currently operating in the Chilean airspace is described. This classification is based on certain acoustic descriptors obtained at a specific noise monitoring point, which are used as inputs for a Feed-Forward Artificial Neural Network. As a result, determined classification groups for the evaluated ai...

The increase in air traffic has the immediate consequence of creating new techniques for air traffic control, as well as new procurement data procedures and data reporting. For these purposes, secondary radars have been developed under the standard ADS-B that should be implemented in coming years on a mandatory basis. In this article, an application of ADS-B radars, capable of introducing the a...

We show that an exact forecast of great radiation hazard in space, in the magnetosphere, in the atmosphere and on the ground can be made by using highenergy particles (few GeV/nucleon and higher) whose transportation from the Sun is characterized by a much bigger diffusion coefficient than for small and middle energy particles. Therefore, high energy particles come from the Sun much earlier (8–...

Nowadays, unmanned aircrafts are more frequently used for measurement purposes. Size of aircrafts is often proportional to its price and load. Aircraft load of 2–3 kg, as required to lift DSLR camera, lens and gimbal (camera stabilizer) in the air, are higher-priced (>50,000 kn). Those kinds of aircrafts have their limits within the law, but also practical limitations because of its size. With ...
