Interaction analysis of back-to-back mechanically stabilized earth walls

Back down to Earth

About a decade ago, systems biology hit the life sciences with the promise that it would revolutionize biological research and create new products, drugs and therapies along the way. As with so many over-hyped ‘breakthroughs’, it inevitably failed to deliver, prompting criticism from a number of eminent biologists. Nobel Prize winner Sydney Brenner, for example, accused systems biologists of us...

08319 - Long Term Corrosion Performance of Soil Reinforcement in Mechanically Stabilized Earth Walls

Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates ...

A New Backward Euler Stabilized Optimum Controller for NPC Back-to-Back Five Level Converters

This paper presents a backward Euler stabilized-based control strategy applied to a neutral point clamped (NPC) back-to-back connected five level converters. A generalized method is used to obtain the back-to-back NPC converter system model. The backward Euler stabilized-based control strategy uses one set of calculations to compute the optimum voltage vector needed to reach the references and ...

Runway Extension With a Vegetated mechanically Stabilized Earth Wall (VMSEW)

Bringing gaze-based interaction back to basics

This paper argues for a joint development of an eye gaze -based, on-line communication aid running on a standard PC with a web -camera. Tracking software is to be provided as open source to allow for improvements and individual integrations with other aids. The interface design shall be defined by the achieved resolution of the tr acking system. The design of a type -to-talk system with 12 larg...
