With the increasing popularity of Wireless Sensor Networks (WSN), indoor localization has become a key research challenge, since it is crucial to locate sensors in order analyze sensor data their spatial and temporal contexts. The paper presents novel method visualize position trajectory dynamic WSN using ZigBee's Received Signal Strength Indicator (RSSI) map-based visualization, deployed on smart phones. Existing demonstrated use RSSI estimate ZigBee tags (transmitters). contribution this...
In picosecond timing detectors, the time over threshold (TOT) of detector signals is normally required to be measured enhance front-edge precision. The extremely narrow pulsewidth these has posed challenges design time-to-digital converters (TDCs) based on field programmable gate arrays (FPGAs) for TOT measurement. this article, an FPGA-based tapped-delay-line (TDL)-type TDC proposed simultaneously measure arrival and nuclear pulses. By propagating hit signal along a single TDL, bubble-proof...
As field programmable gate array (FPGA) becomes an increasingly important digital circuit platform, the voltage fluctuations on its power distribution network (PDN) plays unignorable role in impacting operation and performance. Voltage induced by one block can affect other blocks same chip through PDN, causing performance degradation or even functionality loss critical timing fault. This also opens door to numerous potential attacks that maliciously create transient drops PDN multi-user FPGA...
In large-scale physics experiments, there is a trend to implement clock distribution and synchronization over multi-Gigabit serial links on optical networks.

The front-end electronics for detectors of time- of-flight positron emission tomography (TOF-PET) is required to read out the time and energy detected $\gamma$-events simultaneously. To simplify circuits high integration, we propose an amplitude based time-sampling method with a novel algorithm precisely extract information from measurement. Therefore, traditionally two independent measuring can be merged without losing measurement precision each item. A prototype was implemented fully field...
Generating high-quality novel view renderings of 3D Gaussian Splatting (3DGS) in scenes featuring transient objects is challenging. We propose a hybrid representation, termed as HybridGS, using 2D Gaussians for per image and maintaining traditional the whole static scenes. Note that, 3DGS itself better suited modeling that assume multi-view consistency, but appear occasionally do not adhere to assumption, thus we model them planar from single view, represented with Gaussians. Our...
