      High-level synthesis design methodology - High level synthesis (HLS) [1], also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is ...
    • Nonlinear Fault Detection for Hydraulic Systems 

      Leuschen, Martin L.; Walker, Ian D.; Cavallaro, Joseph R. (2003-01-01)
      One of the most important areas in the robotics industry is the development of robots capable of working in hazardous environments. As humans cannot safely or cheaply work in these environments, providing a high level ...
    • Placement-Related Problems in Shared Disk I/O 

      Sinclair, J.B.; Tang, J.; Varman, Peter J. (1996)
      In a shared-disk parallel I/O system, several processes may be accessing the disks concurrently. An important example is concurrent external merging arising in database management systems with multiple independent sort ...
