The article describes the making of an art piece combining stone sculpture and virtual water. The motivation for this art piece was to enrich the usual static format of a stone sculpture with a dynamic dimension. The dynamic dimension is attained with virtual water droplets running over the stone surface which behave as real water droplets. The 3-D surface of a specially carved stone sculpture ...

In this paper, problem of short-term production planning for dimension stone quarries was mathematically modeled using a binary integer programming. The model includes an objective function, which was founded as the minimization of the costs due to the total cutting planes of the blocks. This objective may cause to maximization of the net present value (NPV) in dimension stone quarries. During ...

Dimension stone as a specific nonmetallic raw material, regarding deposit conditions, exploitation methods and processing, demands an adequate estimate of dimensioning i.e. optimalization of the exploitation in relation to the structural elements. The analyzed and presented examples show that in natural conditions ada tation of the exploitation technology to the discontinuity fatric could resul...
