In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during improvement process, clogging inevitably occurs in drains and soils, hindering water drainage causing inhomogeneous consolidation results. Therefore, it is essential evaluate effect of on behavior slurry at different radii. this study, analytical solutio...

A digital microscopy image is an array of number values, which with adequate contrast can be interpreted as spatial information. Through processing and analysis by mathematical means, using computer-assisted imaging software programs, raw image data contrast can be enhanced to improve the extraction of image features for measurement and analysis. This mathematical feature extraction (referred t...

An omnidirectional platform with an Active Offset Split Caster (ASOC) is described and its ability to operate on non-ideal floors is studied. It is shown that all of its driven wheels of the platform will remain in contact with an uneven floor at all times, a condition necessary to maintain good traction and dead-reckoning capabilities. It is shown that planning algorithms developed for an idea...

The paper argues that micro and macro economists interested in the dynamics of creative destruction can gain important insights by using indices that capture the effect of innovation on the relative position of firms. This is due to the uneven and “destructive” effect that radical innovation has on firm rankings. One such index is the market share instability index. On the financial side, the e...

Potential, Prizes and Performance: Testing Tournament Theory with Professional Tennis Data This paper tests two hypotheses from the theory of elimination tournaments: (i) that uneven tournaments, where the contestants are ex ante heterogeneous, entail lower effort exertion; this is a prediction from agency theory that has not been tested empirically before; and (ii) whether incentives set throu...

Mobile manipulators operating in eld environments will be required to perform tasks on uneven terrain which may cause the system to approach, or achieve, a dangerous tipover instability. To avoid tipover in an automatic system, or to provide a human operator with an indication of proximity to tipover, it is necessary to de ne a measure of stability margin. This work presents a new tipover stabi...
