We propose a new robot actuator, especially a robot actuator gear which has a very effective feature of backdrivability. We show the study of the new definition of backdrivability of an actuator gear which has the quantitative definition. From this definition we propose the method of making the gear which has a good backdrivability. Based on this method,(More)
This work focuses on volume diagnosis for identifying systematic faults in lower-yield wafers, whose yields are lower than baseline level due to systematic faults during mass production. We develop a model-based volume diagnosis method. To diagnose accurately using the fail data with one lower-yield wafer, we apply modeling techniques for handling(More)
The computational complexity of modular multiplication and division, which are the most important operations of some recent public-key cryptographic algorithms, has been a touchy issue for years. This complexity can be efficiently reduced by using prearranged table based on the binary extended GCD algorithm. However, the reduction can be fulfilled if we(More)
