Air cycle systems (ACSs) are primarily used in aircraft environmental control (ECSs) to provide a suitable cabin temperature and pressure environment for passengers avionics. It comprises heat exchangers, compressors, turbines, water separators, various other components that interconnected form an information-transmission network. Traditional research on ACSs has focused their thermal performan...

Supersonic separators have found extensive applications in dehumidification of natural gases since 2003. Unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with Virial equation of state (EOS) to inspect the effect of inlet...

Summary of studies is presented towards minimization of beam loss in the critical locations at the Fermilab Tevatron to reduce background rates in the collider detectors and to protect machine components. Based on detailed MonteCarlo simulations, measures have been proposed and incorporated in the machine to reduce accelerator-related instantaneous and residual background levels in the DØ and C...

We present I/O-efficient algorithms for computing optimal separator partitions of planar graphs. Our main result shows that, given a planar graph G with N vertices and an integer r > 0, a vertex separator of size O(N/ √ r) that partitions G into O(N/r) subgraphs of size at most r and boundary size O( √ r) can be computed in O(sort(N)) I/Os. This bound holds provided that M ≥ 56r log B. Together...

I study active learning in general pool-based active learning models as well noisy active learning algorithms and then compare them for the class of linear separators under the uniform distribution.
