Traffic flow in the Terminal Radar Approach Control Facilities (TRACON) is a significant factor in determining airport throughput capacity and airline operational efficiency. In recent years the availability of high fidelity terminal area track data has made it possible to increase the granularity of airport and airspace performance analysis. This paper describes a methodology for airport arriv...

We present spectroscopy and discuss the photometric history of a previously obscure star in M31. The spectrum of the star is an extremely close match to that of P Cygni, one of the archetypes of Luminous Blue Variables (LBVs). The star has not shown much variability over the past 40 years (< 0.2 mag), although small-scale (0.05 mag) variations over a year appear to be real. Nevertheless, the pr...

The performance of a star tracker is largely based on the availability of its attitude solution. Several methods exist to assess star tracker availability under both static and dynamic imaging conditions. However, these methods typically make various idealizations that can limit the accuracy of these results. This study aims to increase the fidelity of star tracker availability modeling by acco...

The dynamics of star polymers is investigated via extensive molecular and Brownian dynamics simulations for a large range of functionality f and packing fraction eta. The calculated isodiffusivity curves display both minima and maxima as a function of eta and minima as a function of f. Simulation results are compared with theoretical predictions based on different approximations for the structu...

The level-3 trigger system of the STAR experiment will in the final stage consist of a farm of 24 ALPHA/Linux processors, interconnected by SCI (Scalable Coherent Interface). The system will perform online tracking of Ntra k 8000 tracks per event (Npoint 45 per track). The track data will be transfered to a global level-3 CPU (expected data transfer rate '48 MB/s), performing online event analy...

the main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. therefore, railway track desig...
