A method for stimulating bone formation by administering integrin binding compounds which cause the release of osteocalcin from osteoblasts is disclosed. Each of the test blocks generally comprises a plurality of sequential elements and a plurality of logic elements. The performance controlling parameter is set to a predicted value in dependence upon the complexity measure and at least one further processing stage is performed on the at least one data block at the predicted value of the performance controlling parameter. Similarly, all data received while in record mode is designated for permanent storage. The planning engine further retrieves a cycle time of the device, and selects one of the target planning buckets accordingly.
