CLOSE RANGE CALIBRATION OF LONG FOCAL LENGTH LENSES IN A CHANGING ENVIRONMENT
Camera calibration close range physical parameter correlation temperature wavelength
2016/11/11
University College London is currently developing a large-scale multi-camera system for dimensional control tasks in manufacturing, including part machining, assembly and tracking, as part of the Ligh...
Leukocyte telomere length pattern in a Chuvash population that experienced mass famine in 1922–1923: a retrospective cohort study
cohort study famine heritability starvation telomeres
2018/12/18
Background: To our knowledge, there are no experimental studies that have addressed the effects of starvation on the maintenance of telomere length. Two epidemiologic studies that have addressed this ...
Relaxing Full-Codebook Security: A Refined Analysis of Key-Length Extension Schemes
block ciphers key-length extension provable security ideal-cipher model
2016/1/22
We revisit the security (as a pseudorandom permutation) of cascading-based constructions for block-cipher key-length extension. Pre-vious works typically considered the extreme case where the adversar...
Calculating River Length Based on Topography Data
River Length Topographic Data Identifying Mainstream Centerline Multiple Criteria Decision
2015/12/11
River length has been the particular interest of people. Topographic data, which are obtained from field survey or digitizing from topographies, can serve as ideal data source for river length calcula...
DEM GENERATION WITH SHORT BASE LENGTH PLEIADES TRIPLET
Space Adjustment DEM/DTM Georeferencing Radiometric Accuracy Performance
2015/4/1
An image triplet of Pleiades images covering the area of Zonguldak, Turkey has been investigated. The height to base relation of the first to the last image is just 1:4.5 and for the first and the sec...
Hardware Implementation of Queue Length Based Pacing on NetFPGA
small-buffers optical networks pacing netfpga
2014/12/8
Optical packet switching networks are the foundation for next generation high speed Internet and are fast becoming the norm rather than an option. When such high speed optical networks are taken into ...

Ozone Depletion Stratospheric Cycles Chain Propagation
2013/2/27
Algorithm for calculation of the chain length and rate of stratospheric ozone depletion in Ox, HOx, NOx, ClOx and BrOx cycles has been developed. The most important new element in the theory of strato...
Effects of polymer concentration and chain length on aggregation in physically associating polymer solutions
concentration chain length aggregation associative polymer
2012/2/24
The effects of polymer concentration and chain length on aggregation in associative polymer solutions, are studied using self-consistent field lattice model. Only two inhomogenous morphologies, i.e. m...
