Laser Footprint Size and Pointing Precision Analysis for LIDAR Systems
LiDAR Data Accuracy Analysis Laser scanning
2015/11/20
Laser footprint size and beam divergence angle tuning was found to affect LiDAR data accuracy and measurement precision because of beam axis shifting. The laser beam divergence angle is generally tuna...

How Small Should Pixel Size Be?
Signal-to-Noise Ratio(SNR) Dynamic Range(DR) Modulation Transfer Function(MTF)
2015/8/17
Pixel design is a key part of image sensor design. After deciding on pixel architecture, a fundamental tradeoff is made to select pixel size. A small pixel size is desirable because it results in a sm...
Optimal Throughput-Delay Scaling in Wireless Networks–Part II:Constant-Size Packets
Throughput-Delay Scaling Wireless Networks Constant-Size Packets
2015/8/12
In Part I we characterized the optimal throughput-delay trade-off in static wireless networks as D(n) = Θ(nT(n)), where D(n) and T(n) are the average packet delay and throughput in a network of n node...
STATE-DEPENDENT MIXTURE TYING WITH VARIABLE CODEBOOK SIZE FOR ACCENTED SPEECH RECOGNITION
State-dependent tied mixture models variable codebook size
2013/6/27
In this paper, we propose a state-dependent tied mixture (SDTM) models with variable codebook size to improve the model robustness for accented p honetic variations while maintaining model discrimina...
