Man-machine interface problems in designing air traffic control systems
Article Abstract:
Human-machine interfaces in future air traffic control (ATC) systems must improve on the communication of information between air traffic controllers and the computers monitoring the ATC network. ATC workspaces should be studied through application of ergonomic, anthropometry, occupational health and other data. It is important to consider the physical characteristics of the environment and workspace as well as legal and occupational health standards. The system must be flexible enough to handle variations in staff levels to assure that the workload for individual controllers is never excessive. The system must make correct assumptions about what controllers know and what information they must be told. The effect of reducing the time taken to handle each aircraft is discussed, and various functions of the human-machine interface are examined.

Classification of radar clutter in an air traffic control environment
Article Abstract:
Radar detection schemes consider non-aircraft targets as undesirable 'clutter' that must be suppressed to enhance the visibility of aircraft within the clutter areas. The moving target indicator (MTI) is in effect a Doppler filter intended to remove all non-moving echoes such as ground clutter. Moving target detectors (MTDs) are comprised of a bank of Doppler filters, each of which is tuned to a different frequency, and separate targets and clutter by determining their velocity. In the technique described here, an attempt is made to classify different forms of radar signals instead of merely detecting moving targets; the work is a generalization of the target detection problem because detection can be considered a simple classification with two classes.

Transient mean and variance of overflow traffic in a loss system
Article Abstract:
The mean and variance of the overflow traffic in a telephone system can be approximated using simple techniques. After approximating the mean, the peak value is found by using the interrupted Poisson process. The variance can then be approximated.
