Natural hazards threaten many archaeological sites in the world; therefore, susceptibility analysis is essential to reduce their impacts and support site fruition by visitors. In this paper, rockfall of western slope Cumae Mount Archaeological Site (Phlegraean Fields, Naples), already affected events, described as a management plan for conservation. Being first Greek settlement southern Italy, ...

In this article, a novel yet simple step climbing robot is proposed and comprised of two front wheels, rear-wheel an actuator to vary the center distance between rear wheels. When climbs stair, huge variance in inclination angle may result its toppling. Hence, mechanism compensate for change angle. An inertial measuring unit (IMU) used sense which then fed microcontroller order actuate connecti...

The predisposition of a slope to generate rockfalls is related the intensity rock mass jointing and geometric arrangement discontinuities intersecting face. With increasing use terrestrial laser scanner (TLS) in surveying, methods have been proposed semi-automatically extract spatial properties outcropping from high-resolution topographic data. present paper builds upon one such (named DiAna), ...

Abstract Flood risk assessment requires a quantitative understanding of hazards and vulnerability. In the coastal built environment, human's vulnerability to combined due floodwater winds is an integral component flood risks. The present study aims reveal human storm‐induced flooding, focusing on New York City during Hurricane Sandy. We develop physics‐based model quantify individuals' physical...

We prove the dimensional reduction conjecture of Fey, Levine, and Peres (2010) on hypercube. The proof shows that reduction, symmetry, regularity Abelian sandpile persist during parallel toppling process. This stronger result verifies empirical observations first documented by Liu, Kaplan, Gray (1990).

Occurrence of toppling failure has been prominent due to the increasing infrastructure construction, such as road slopes, dams, and hydroelectric stations. Many scholars have done research on characteristics, but paid less attention comparison numerical simulations physical models in order propose reasonable effective stability control methods. Based previous tests model field investigations, a...

The Fixed Energy Sandpile with the deterministic Bak-Tang-Wiesenfeld rule on the two-dimensional torus, is studied in order to characterize existence and growth rate of the basins of periodic avalanches. The link between discrete harmonicity and invariant quantities, or toppling invariants, is shown. For an important subclass, these invariants are proven to be related to discrete harmonic polyn...
