高斯自由 伯努利渗透 相变存在
2023/5/8
In this talk, we prove that Bernoulli percolation on graph undergoes a non-trivial phase transition if the graph has bounded degrees and random walk on the graph has a heat kernel with rapid decay. Th...
ALESSANDRO ANTONELLI AND THE BAROQUE PRE-EXISTENCE: THE PROJECT FOR THE NATIONAL PARLIAMENT IN TURIN
Alessandro Antonelli National Parlament Turin 3D modeling Digital History

The contribution is focused on Alessandro Antonelli’s project for the seat of the new italian parliament in Turin. The project, unrealized, began back in 1860, when the annexation to the Piedmont of T...
Using Motion-Planning to Determine the Existence of an Accessible Route in a CAD Environment
Accessibility wheeled mobility device motion planning simulation performance-based methods computer-aided design and drafting
2015/6/30
We describe an algorithm based on motion-planning techniques to determine the existence of an accessible route through a facility for a wheeled mobility device. The algorithm is based on LaValle’s wor...

Shape Co-existence medium spin 76Rb
2011/7/20
Four previously known rotational bands in 76Rb have been extended to moderate spins using the Gammasphere and Microball gamma ray and charged particle detector arrays and the 40Ca(40Ca,3pn) reaction a...
The criterion of the existence or inexistence of transverse shock wave at wedge supported oblique detonation wave
Oblique detonation wave Transverse shock wave Oblique shock wave Transition Numerical simulations
2012/2/29
A simplified theoretic method and numerical simulations were carried out to investigate the characterization of propagation of transverse shock wave at wedge supported oblique detonation wave. After s...
Existence and Uniqueness of the Optimal Control in Hilbert Spaces for a Class of Linear Systems
Existence and Uniqueness Optimal Control Controllable Linear Systems Linear Operator
2013/1/28
We analyze the existence and uniqueness of the optimal control for a class of exactly controllable linear systems. We are interested in the minimization of time, energy and final manifold in transfer ...

Magnetorheological elastomers Bound-Rubber Storage modulus
2015/3/30
In e®orts to develop a new fabrication method for improvement of the MREs' performance, the bound- rubber phenomenon was observed in MREs. Further experiments indicate the existance of bound-rubb...
Simple geometric criterion to predict the existence of surface modes in air-core photonicbandgap fibers
Fiber design and fabrication Fiber optics optical communications
2015/8/11
We propose a simple geometric criterion based on the size of the core relative to the photonic crystal to quickly determine whether an aircore photonic-bandgap fiber with a given geometry supports sur...
