Noise floor is a frequency spectrum parameter that is widely used in ADC testing although it has not been properly defined and described by a formula in any ADC standards yet. IEEE Std 1057-1994 does not mention the noise floor but it generally uses noise or noise level that is not defined. IEEE Std 12412000 provides a formula for noise floor computation depending on the number of ADC bits; con...

This paper presents the subjective difference of floor impact sound of wood-frame floors with different floor-ceiling systems. All impact sounds of wood-frame floors were measured in reverberation chamber with standardized rubber ball. The impact sound of concrete floor was also measured. Sheffe’s paired comparison method was used to obtain psychological scale values of each impact sound. The l...

The majority of childbirth injuries to the pelvic floor occur after the first vaginal delivery. Cesarean sections performed after the onset of labor may not protect the pelvic floor. Elective cesarean section is the only true primary prevention strategy for childbirth injuries to the pelvic floor. Alternative primary prevention strategies include elective cesarean section for women with nonmodi...

A method to segment a floor and an obstacle region from images, is a fundamental function for robots in real-world. This paper describes a floor detection method by integrating binocular stereo vision and whole body information, for walking direction control of a humanoid robot. We developed the humanoid robot navigation system using vision based local floor map. The developed system consists o...
