IN THE study of the APRL-Sierra No. 1 right hand, which preceded that of the left, the results of comparative performance testing indicated that there was little difference between the hand and the hook on the various test activities. Statements of children participating in the study—and of their parents—indicated a relatively high level of performance with the experimental hand, but advantages...

The performance testing of baseball bats for potential use in regulating bat performance is best completed using the same baseballs as are used in a game. In the current research, the effects of repeated use of baseballs in testing are explored. The batball performance is compared with ball performance off a rigid wall, and the consistency of both batand ball-performance metrics during bat-ball...

Performance modelling is simulation of the user inputs and then altering the systems' configuration in order to monitor performance of software. Performance modelling rarely incorporated but gradually we have realized its significance. There are various approaches for modelling and each has its own benefits and hindrances. Performance modelling when applied on the cloud is again a very cha...

The performance of the control system is an important aspect of a machine. It would be a waste if a high-tech machine has been build such that it can physically achieve a high throughput, for example printed sheets of paper, but is limited because the software controlling it cannot keep up. Unfortunately, with current techniques it is hard to “predict” beforehand what the performance of the sof...
