[1] Alluvial fan deltas are built by aggrading and avulsing river channels. A numerical model of flow and sediment transport in channels is combined with a condition for channel avulsion to describe evolution of the fan surface. The model combines elements of two recent approaches: (1) diffusional models of depositional basin filling, which describe the evolution of overall morphology, and (2) ...

This paper proposes a comparator design using conventional digital CMOS cells featuring wide-range and high-speed operation. The Comparison is most basic arithmetic operation that determines whether one number is greater than, less than or equal to the other number. Our comparator uses a novel scalable parallel prefix structure that leverages the comparison outcome of the MSB, proceeding bitwis...

We present the results of an experimental study of alluvial fan sedimentation under conditions of constant inflow water discharge Qw, sediment supply Qso, and median grain size D. The study was designed to complement and test a recently formulated model of alluvial fan sedimentation and to emphasize the interactions between, and controls on, flow channelization and equilibrium fan slope. Flow c...

In the desert of Abarkoh Basin, Central Iran, the influence of playa-lake level fluctuations on recent sedimentation mode of a terminal ephemeral fluvial-fan system and adjacent lacustrine/aeolian sediments of a playa fringe environment has been investigated. The surface geomorphology-sedimentology and its relationship with shallow subsurface sediments along a >25 km transect, has been studied....

Flutter was encountered at part speeds in a scaled wide chord fan blisk designed for civil aeroengine during rig test when the bypass flow throttled toward its stall boundary. Analysis of blade tip timing measurement data revealed that blades vibrated first flap (1F) mode with nodal diameters two and three. To facilitate further ultimately eliminate flutter problem, numerical campaign launched ...

we find an explicit expression of the tutte polynomial of an $n$-fan. we also find a formula of the tutte polynomial of an $n$-wheel in terms of the tutte polynomial of $n$-fans. finally, we give an alternative expression of the tutte polynomial of an $n$-wheel and then prove the explicit formula for the tutte polynomial of an $n$-wheel.

The paper reports on the development and evaluation of a simple closed loop solution for controlling the CO2 levels within small enclosed environments, such as Explosive Ordnance Disposal (EOD) protective suit helmets. Based on a detailed analysis of the helmet environment during bomb disposal missions, the solution proposed automates the current manually controlled fan integrated within the he...

designing FIR fan filters suitable for the multibeam forming network of the wideband beamspace adaptive array. Characteristics were approximated through the combination of spectral transformation and the window method so that those beam patterns that included the sidelobe characteristics of the resulting fan filters were virtually frequency independent. Using the fan filters designed by the pro...
