Moisture and thermal diffusivity of lentil seed under convective infrared-microwave:Modelling with and without shrinkage
infrared radiation equilibrium content Fick’s second equation drying rate dehydration
2016/9/2
The effect of infrared radiation and microwave radiation on the moisture and thermal diffusivity characteristics of lentil seeds during infrared and microwave drying was investigated. Using mathematic...
RESEARCH ON THE REASONS FOR ANGULI LAKE′S SHRINKAGE AND DRYING UP USING SATELLITE REMOTE SENSING
Anguli Lake Remote Sensing Image Troughs Temperature Rise Shrinkage and Drying up
2016/1/3
There are a group of arc lines in the remote sensing image beside Anguli lake. Through interpretation image carefully, we find which are not only parallel to each other, but also to the lake east shor...
Speckle Denoising Based on Bivariate Shrinkage Functions and Dual-Tree Complex Wavelet Transform
Transformation Algorithms SAR Radiometric Processing, Image
2015/11/20
Bivariate shrinkage functions (bsf) statistically denoted as joint probability density functions (pdf) and noise pdf, can be united by MAP to denoise image. Because the intensity of speckle in synthet...
Adapting to Unknown Smoothness via Wavelet Shrinkage
Minimax Decision theory Stein's Unbiased Estimate of Risk
2015/8/20
We attempt to recover a function of unknown smoothness from noisy, sampled
data. We introduce a procedure, SureShrink, which suppresses noise by thresholding
the empirical wavelet coecients. The th...
Measurement of Shrinkage In Concrete Samples By Using Digital photogrammetric Methods
Calibration Close Range Adjustment
2015/7/14
This paper shows the use of digital photogrammetry for measurement of shrinkage in concrete sample (4x4x22 cm) during the hydration
process. A vision system consist of two digital video cameras was e...
