Multiple acquisitions ( next figure ) may be required when the government wishes to assert greater control over developing and evolving the underlying architecture and its components . The PARBOOT application splits a multiple-dataset inputfile into its independent datasets , and processes these datasets in parallel on multiple hosts ( or one host with multiple CPUs ) . Specific topics include : motion planning in the presence of multiple constraints ( obstacle avoidance , maintenance of equilibrium , as well as kino-dynamic , visibility , and contact constraints ) , assembly sequence planning , making decisions under sensing and control uncertainty , construction of 3-D geometric models of complex environments , visual tracking of rigid , articulated and deforming objects , and reasoning in multiple-agent worlds . In the case of NETCONF , it is important to consider that device management may be taking place over multiple substrates ( in addition to SOAP ) , and it is important that the different substrates have a common authentication model . The laboratory also has multiple ECGs ( electrocardiograms ) to monitor cardiac functioning during exercise , including an integrated stress testing system .
