Slope stability is calculated using several methods. All these methods produce estimated results based on inaccurate assumptions, and their were particularly acceptable. Furthermore, rely supposing segmenting the surface of failure as well performing complex calculations. This paper introduces “Dimensional Analysis Technique” a new approach for dealing with earthen slopes. Four dimensionless gr...

despite providing robustness, high-gain observers impose a peaking phenomenon, which may cause instability, on the system states. in this paper, an adaptive saturation is proposed to attenuate the undesirable mentioned phenomenon in high-gain observers. a real-valued and differentiable sigmoid function is considered as the saturating element whose parameters (height and slope) are adaptively tu...

Optimization methods for curvilinear reinforcements placement aims to improve mechanical response of structure. Whenever a gradient-based method is used optimization, it necessary arbitrate an initial the fibers. This guess has influence on result. work observe positioning straight carbon fiber in epoxy resin plates, which had their compliance minimized by Sequential Linear Programming. The max...

The slope stability is a very important problem in geotechnical engineering. This paper presents an approach for slope reliability analysis based on the maximum-entropy method. The key idea is to implement the maximum entropy principle in estimating the probability density function. The performance function is formulated by the Simplified Bishop’s method to estimate the slope failure probabilit...

Data obtained recently by the Mars Orbiter Laser Altimeter (MOLA) were used to study the statistical properties of the topography and slopes on Mars. We find that the hemispheric dichotomy, manifested as an elevation difference, can be described by long baseline tilts but in places is expressed as steeper slopes. The bimodal hypsometry of elevations on Mars becomes unimodal when referenced to t...

We have found that debris flows are the main process in forming two gullied crater slopes on Mars. We used 1 m/pix elevation models to derive three topographic indices: slope-area, CAD and DI-25. These indices allow the active slope processes to be identified by comparison to data from Earth analogues. We present data from Meteor Crater together with analogues previsouly presented by Conway et ...
