Vt instability caused by grain-boundary trap (GBT) in the poly-crystalline silicon (poly-Si) channel of a 3D NAND string are comprehensively studied. Experimental results reveal that trapping/detrapping of GBT would cause transient cell current with a time constant of 10us or longer, and this transient is strongly affected by the bias history. Sensing offset between program/erase verify (PV/EV) and...
We propose and demonstrate cross-stratum Broker orchestration for scientific applications and heterogeneous resources reservation in DCs, HPC facilities and networks belonging to different operators. Experiments were performed in a distributed set-up spanning across three continents.
A self-healing mmWave SoC integrating an 8052 microcontroller with 12kB of memory, an ADC, a temperature sensor, and a 3-stage cascode 60GHz LNA, implemented in a 32nm SOI CMOS technology exhibits a peak gain of 21dB, an average 3.3dB NF from 53 to 62GHz and 18mW power consumption. An indirect NF sensing algorithm was implemented on the integrated uC, which enables an adaptive biasing algorithm to...
Fall injury is already a major problem in elderly health care. This work develops a self-adaptive fall-detection apparatus which is embedded in glasses for users easily to put on. The proposed system adopts a 9-axis sensing module of a triaxial magnetometer, accelerometer and gyroscope. First, the magnetometer is to filter out some normal events like head rotating, based on variations of rotation...
Vector transducers generate or measure signals in the vector components of the acoustic field. Examples of the vector components are acoustic particle velocity and acoustic particle acceleration. In recent years underwater communication schemes using vector projectors as transmitters and vector sensors as receivers have been proposed. Therefore the need for characterization of the vector components...
We present a novel algorithm for radar imaging of point scatterers using a sparse number of spatially separated sensors. Such sparse sensing scenarios are prototypical of many applications wherein a limited number of sensors are distributed over a geographical area; or where environmental and/or systemic constraints enforce a sparse sampling of angular aperture. Our underlying assumption is that the...
In this study, we design and present the novel wearable system with the interactive posture caption and recognition functions based on the non-vision over the ZigBee wireless sensor network (ZigBee-WSN). There are two type sensors, 3-axis accelerometer and clip type, to be employed in our wearable system. These sensors are arranged on user's four limbs such that the posture information can be gathered...
We present a compressive programmable array microscope design, which incorporates the compressive sensing principle into the patterned illumination microscope design, so that single pixel detectors can be used to capture microscopic images without mechanical scanning.
Tilted fiber Bragg gratings have been demonstrated to be accurate refractometers. Because they require spectral measurements on several tens of nanometers, demodulation techniques reported so far are not suited for quasi-distributed refractive index sensing using TFBGs cascaded along a single optical fiber. We demonstrate here that a commercial OTDR can be used to multiplex identical TFBGs refractometers...
