A 20-m-wide trench was excavated to bedrock on a hillslope at the Panola Mountain Research Watershed in the Piedmont region of Georgia to determine the effect of upslope drainage area from the soil and bedrock surfaces on the geochemical evolution of base cation concentrations in subsurface flow. Samples were collected from ten 2-m sections and five natural soil pipes during three winter rainst...

Diverse observations from the 2011 Mw 9.0 Tohoku-oki earthquake pointed to large coseismic fault slip proximal to the Japan Trench. This seismic failure prompted a reevaluation of the conventional view that the outer forearc is generally aseismic. However, the nature of near-trench fault slip during this event remains debated, without consensus on whether slip peaked at the trench or at greater...

[1] The Challenger Deep in the southernmost Mariana Trench (western Pacific Ocean) is the deepest point on the Earth’s surface (10,920 m below sea level). Its location within a subduction trench, where one plate bends and descends below another, is not surprising. However, why is it located in the southernmost Mariana Trench and not at its central part, where the rate of subduction is higher, w...

A viscous flow model of a subduction zone is used to calculate the near-trench deformation and topography of the overriding plate in response to tectonic and buoyancy forces. The tectonic force, which is associated with global plate motion, arises from subduction of a cold oceanic lithosphere that shears the overriding lithosphere along the contact between the two plates. The buoyancy force ari...

Introduction This is the third paper in a series of white papers addressing the issues associated with the usage of optical fiber cables in space flight applications.[1-2] These experiments to characterize commercially available optical fiber cables are crucial to deciding which cables are appropriate for which space flight mission based on their environmental performance. The objective of this...

The cable model is widely used in several fields of science to describe the propagation of signals. A relevant medical and biological example is the anomalous subdiffusion in spiny neuronal dendrites observed in several studies of the last decade. Anomalous subdiffusion can be modelled in several ways introducing some fractional component into the classical cable model. The Chauchy problem asso...

We present the simulated dynamics and control of a planar, translational cable-direct-driven robot (CDDR). The motivation behind this work is to improve the serious cable interference problem with existing CDDRs and to avoid configurations where negative cable tensions are required to exert general forces and moments on the environment and during dynamic motions. Generally for CDDRs the command...

The towing of an underwater object by means of a cable attached to a ship is an important problem in underwater technology. An underwater towed body is generally at the mercy of hydrodynamic and hydrostatic forces, which controls its motion through water. These forces affect the depth characteristics of the towed body giving specific configuration to the towline. This work consists of the devel...

This paper presents an algorithm, based on a Monte Carlo method, to assess the yearly expected number of failures to buried optical fibre cables (provided with metallic components) due to direct lightning strokes. The random parameters that have been considered in the algorithm are the lightning peak current, the distance between the cable and the point of impact of the stroke to soil and the c...

This article deals with new ways of far-end crosstalk (FEXT) modeling in multi-pair and multi-quad metallic cables. Current standard modeling methods provide only rough estimations of FEXT characteristics based on average values of crosstalk for the whole cable. However, for practical implementation of vector discrete multi-tone modulation (VDMT) is necessary to predict and simulate FEXT charac...
