3D-VNAND Depth Measurement Using OFI Lock-In OBIRCH
International Symposium for Testing and Failure AnalysisAbstract To increase yield and cost competitiveness, FLASH memory device developed vertical stack 3D-VNAND. Furthermore, we introduced Cell over Peripheral (COP), which places peripheral circuits, which were previously located at the same level as memory cells, under the memory cells, thereby reducing the chip size and increasing the ...

No apparent lock-in depth of the Laschamp geomagnetic excursion: Evidence from the Malan loess
Science in China Series D: Earth Sciences, 2006The first-order chronological framework of the long-term Chinese loess/paleosol sequences was based mainly on magnetostratigraphy. However, there remain arguments on the lock-in ages of the major geomagnetic reversals. This study systematically compared the stratigraphic locations of the Laschamp excursion and Henrich events (H4 at ∼39 ka and H5 at ∼48

Effects of submersion depth on the dynamics and deposition of lock-release turbidity currents
Physics of FluidsThis study investigates the influence of the submersion depth on the propagation dynamics and the deposition patterns of turbidity currents using the lock-release configuration. While previous studies have investigated the effects of submersion depth on conservative density currents, its impact on non-conservative, particle-laden currents has received ...

Detection of a locked zone at depth on the Parkfield, California, segment of the San Andreas Fault
Journal of Geophysical Research: Solid Earth, 1987The Parkfield, California, segment of the San Andreas fault is transitional in character between the creeping segment of the fault to the northwest and the locked Carrizo Plain segment to the southeast. The rate of shallow fault slip decreases from 25–30 mm/yr northwest of the epicenter of the 1966 Parkfield earthquake to zero at the southeastern end ...

3D object recognition using Kernel PCA based on depth information for twist-lock grasping
2013 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2013The handling of twist-locks has been a heavy burden for the container industry. There have been many efforts in developing automated twist-lock handling solutions. To address this challenge, we are developing a customized mobile manipulator for twist-lock pose estimation and grasping.

Injection-depth-locking axial motion guided handheld micro-injector using CP-SSOCT
2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014This paper presents a handheld micro-injector system using common-path swept source optical coherence tomography (CP-SSOCT) as a distal sensor with highly accurate injection-depth-locking. To achieve real-time, highly precise, and intuitive freehand control, the system used graphics processing unit (GPU) to process the oversampled OCT signal with high ...
