Thresholds in the sliding resistance of simulated basal ice

We report laboratory determinations of the shear resistance to sliding melting ice with entrained particles over a hard, impermeable surface. With higher particle concentrations and larger particle sizes, Coulomb friction at particlebed contacts dominates and the shear stress increases linearly with normal load. We term this the sandy regime. When either particle concentration or particle size ...

Basal sliding of Ice StreaIll B , West Antarctica

A "tethered sta ke" appa ra tus is used to measure basal sliding in a borehole on Ice Stream B, 'Nest Antarctica, a bout 300 km upstream (east) from its g rounding line near the head of the R oss lee Shelf. A meta l sta ke, emplaced at the to p of a layer of unfrozen till underlying the ice, is connected by a tether line to a metering unit that measures the te ther line as it is pulled out from...

Modified OFDM Model Based on Sub-Sliding Window Technique

In modern wireless communication systems, Doppler frequency reduction is employed for efficient transmission of data in noisy environments. Achieving a very less bit error rate (BER) has been the major task in the orthogonal frequency division multiplexing (OFDM), which is a popular multicarrier modulation technique in IEEE 802.11a wireless systems and is currently being used in the IEEE 802.16...

Leaf area relationships to plant vegetative characteristics in cotton (Gossypium hirsutum L.) grown in a temperate sub-humid environment

Measurement or estimation of leaf area is essential for understanding crop responses to experimental treatments. The objective of this study was to develop regression models for estimating leaf area of field-grown cotton (Gossypium hirsutum L.) from measurements of leaf dry weight (LDW), vegetative components (stems and leaves) dry weight (VDW) and plant height (PH). Three cotton cultivars (Del...
