This paper presents an emulation tool and the way in which it supports the test-driven design of zerodeadlock cut-to-size plants. In contrast to previous plant layouts featuring a linear material flow, panels can now be allocated to the same saw again for their further partitioning. The resulting circles in the material flow of cut-to-size plants impose new challenges as they may cause deadlock...

Issue: The moisture content of a fill material will affect its compaction characteristics and needs to be evaluated during quality control of the fill operation. When the fill is drier than its optimum moisture content, any moisture in the fill serves as a lubricant and helps the relative movement of the particles when densifying under vibratory compaction. When the fill is wetter than its opti...

The effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water t...

World-wide large repositories of learning material are created with the dual goals of global access for the learner and of re-use of material by the teacher. Content description standards have been defined which make it possible to locate appropriate material. This paper looks into complementing these standards by extending the possibilities of describing the actual content of the learning mate...
