The faces of the original block, slab, or cylinder of material can usually still be sensed, existing around the finished work as a kind of implied spatial envelope limiting the extension of the forms in space and connecting their highest points across space.
The SEL model on the other hand depicts more closely the current state-of-the-art in HPA designs for cellular systems where approximately linear behavior is obtained in the small signal conditions, followed by clipping (soft envelope limiting) at saturation.
The paper deals with the application of the so-called Reference (or Command) Governor constrained control strategy to the shape control of plasmas in thermonuclear fusion reactors with the main scope of optimizing tokamak operations also in conditions very close to the operating envelope limits.
The USMC trains pilots in the recognition of and recovery from VRS, and has instituted operational envelope limits and instrumentation to help pilots avoid VRS conditions.
The thickness of the envelope limited the diameter of the distal optics to about 1.8 mm.
Gan et al. suggested that apoptosis, which results in a 'cellular corpse' with an impermeable envelope, limits mycobacterial replication and facilitates antigen presentation.
"UK officials, including the Financial Services Authority, will 'push the legal envelope' to limit Iranian banking activity by both Iranian and UK financial institutions in London and UK diplomats in Brussels will lead the charge for very tough language in the EU common position on Iran, Neil Kernohan, the sanctions officer for the FCO's Iran coordination group, said".
A bioclimatic approach to designing comfortable buildings in hot and humid tropical regions requires, firstly, some preliminary, important work on the building envelope to limit the energy contributions, and secondly, an airflow optimization based on the analysis of natural ventilation airflow networks.
These EPs can transport drugs through the bacterial envelope and limit the intracellular accumulation of toxic compounds, such as antibiotics, antimicrobial peptides, metals and detergents [ 32].
In many cases the space for additional insulation in the building envelope is limited.
