2020 arXiv   pre-print
Typically, mobile manipulators are deployed in slow-motion collaborative robot scenarios. In this paper, we consider scenarios where accurate high-speed motions are required.  ...  We evaluate our framework with a mobile manipulator platform through numerous high-speed ball catching experiments, where we show a success rate of 85.33%.  ...  We focus on a benchmark task for accurate high-speed motions: object catching, specifically, ball catching.  ...

2005 Proceedings of the 19th annual international conference on Supercomputing - ICS '05  
This paper presents TAPE, a hardware and software infrastructure for profiling in TCC systems.  ...  TAPE accurately identifies the source code location and type of the most important bottlenecks, allowing a programmer to achieve maximum parallel speedup with a few profiling steps.  ...  In the next subsections, we describe how the profiling hardware aggregates data for each bottleneck to produce useful and accurate information at a fraction of the cost of the naïve approach.  ...

Phase guided profiling for fast cache modeling

Andreas Sembrant, David Black-Schaffer, Erik Hagersten
2012 Proceedings of the Tenth International Symposium on Code Generation and Optimization - CHO '12  
The result is a new technique that accurately models the time-varying behavior of an application's miss ratio as a function of its cache allocation on modern hardware.  ...  In this work we extend earlier techniques to incorporate program phase information when collecting runtime profiling data.  ...  This makes it a particularly tricky application to profile accurately.  ...

2020 International Journal for Research in Applied Science and Engineering Technology  
The accurate measurement of the gears plays an important role in measuring and checking the gears. The tools currently in use are either time consuming or expensive.  ...  In addition, some measurement methods can not be used and this allows accurate measurements of all gear ratios, but significantly reduces the time.  ...  In sequence to better hold the accuracy of fishing gear, it is important to accurately check gear ratios.  ...
