However, their shortcomings particularly include defciencies in the achievable positioning and path accuracy. The backlash as one of the main issues is well described in the literature and numerous solutions to reduce its negative efects exist. In contrast, there is a lack of literature regarding the scientifc and systematic analysis of the transmission errors in rack-and-pinion drives. In this paper, the displacements originating in the drive train of a system with industrial components are measured under diferent operating conditions. The observed transmission errors are thoroughly analyzed in no-load operation and their sources are discussed. Subsequent investigations show signifcant load-dependent alterations of the transmission errors and direction-dependent characteristics, the causes of which are explained. It is shown, that transmission errors negatively afect the path accuracy of position controlled drives, which is amplifed by excitation of the machine structure in certain operating conditions. To address this issue, diferent error compensation concepts are presented.Mon Mar 19 16:15:07 CET 2018Proceedings of the IEEE International On-Line Testing Symposium (IOLTS'13)240--243{Efficacy and Efficiency of Algorithm-Based Fault Tolerance on GPUs}2013ABFT GPGPU SimTech algorithm-based computing errors fault fault-tolerance myown scientific simulation Computer simulations drive innovations in science and industry, and they are gaining more and more importance. However, their high computational demand generates extraordinary challenges for computing systems. Typical highperformance computing systems, which provide sufficient performance and high reliability, are extremly expensive. Modern GPUs offer high performance at very low costs, and they enable simulation applications on the desktop. However, they are increasingly prone to transient effects and other reliability threats. To fulfill the strict reliability requirements in scientific computing and simulation technology, appropriate fault tolerance measures have to be integrated into simulation applications for GPUs. Algorithm-Based Fault Tolerance on GPUs has the potential to meet these requirements. In this work we investigate the efficiency and the efficacy of ABFT for matrix operations on GPUs. We compare ABFT against fault tolerance schemes that are based on redundant computations and we evaluate its error detection capabilitiesThu Mar 03 09:53:12 CET 2016--Verification of machine tool functionality by using Hardware in the Loop and manufacturingsimulation, The Fourth Wroclaw CIRP Symposium AP 2003 11-12.12.2003: Verification of machine tool functionality by using Hardware in the Loop and manufacturingsimulation, The Fourth Wroclaw CIRP Symposium AP 2003 11-12.12.20032003Control, Hardware ISW Loop, Machining, errors in path the In order to achieve the highest machining precision, errors in a manufacturing unit need to becompensated for. The Hardware in the Loop simulation was designed as a verification andvalidation tool for CNC systems. The technological innovation is that the entire platform,simulated machine and control system, runs under hard real time conditions. The dynamic andcutting path errors can then easily be seen and analysed. A comparison between the visulisationand a physical work piece has proven this simulation method to be valid.errorsCommunity for tag(s) errors
