The tolerance balancing optimization with multiple constraints on the form and function of the discrete functional surface [PDF]
Scientific ReportsThe working performance of the discrete functional surface is affected by the surface form. Both the surface form and the geometric function should be considered in tolerance design.

Geometrical Tolerances—Separate, Combined or Simultaneous? [PDF]
Applied Sciences, 2023 The 14 geometrical tolerances defined in ISO 1101 are supplemented by the alphanumerical symbols defined in this standard and some other standards. The symbols CZ (combined zone), SZ (separate zones) and SIM (simultaneous requirement), which are crucial for the development of robust measuring programs for coordinate measuring machines, were introduced ...

Fault-tolerant geometric spanners [PDF]
Proceedings of the nineteenth annual symposium on Computational geometry, 2003 We present two new results about vertex and edge fault-tolerant spanners in Euclidean spaces. We describe the first construction of vertex and edge fault-tolerant spanners having optimal bounds for maximum degree and total cost. We present a greedy algorithm that for any \(t > 1\) and any non-negative integer \(k\), constructs a \(k\)-fault-tolerant ...

Tolerances in Geometric Constraint Problems [PDF]
Reliable Computing, 2005 Geometric constraint solving is a term of computer-aided design and means the problems which arise when the location of geometric objets is described via geometric relations between them. The issues crucial for engineering applications are solvability of constraint problems and the sensitivity to errors.
