Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Contact discontinuities in finitely long nozzles
有限长喷嘴 接触 不连续性 可压缩欧拉流
2023/5/4
There can be contact discontinuities in the nozzle for the compressible Euler flow. In this talk, we will talk about the cases of the subsonic-supersonic and supersonic-supersonic contact discontinuit...
RECONSTRUCTING BUILDINGS WITH DISCONTINUITIES AND ROOF OVERHANGS FROM OBLIQUE AERIAL IMAGERY
Aerial Oblique Building Reconstruction Discontinuities Roof Overhangs Texture Mapping CityGML
2017/7/13
This paper proposes a two-stage method for the reconstruction of city buildings with discontinuities and roof overhangs from oriented nadir and oblique aerial images. To model the structures the input...
Lapses: How People Arrive at, and Deal With, Discontinuities in Talk
Discontinuities People
2015/12/18
Interaction includes moments of silence. When all participants forgo the option to speak, the silence
can be called a “lapse.” This article builds on existing work on lapses and other kinds of silenc...
Discontinuities of Weak Instrument Limiting Distributions
weak instruments two stage least squares near non-identiÖ cation
2015/9/22
We consider two stage least squares (2SLS) estimators of a simple simultaneous equations
model when identiÖcation fails asymptotically. We investigate how the limiting distribution
of the estim...

Non-linear effects in ground deformation at calderas due to the presence of structural discontinuities.
EXTRACTION OF PLANAR PATCHES FROM POINT CLOUDS TO RETRIEVE DIP AND DIP DIRECTION OF ROCK DISCONTINUITIES
Risk assessment Geomorphology Photogrammetry
2015/8/13
Laser scanners and image matching algorithms produce large amounts of 3D data, allowing detailed and accurate descriptions of
objects. This is true, though, only if interactive or automated software...
Spatial continuities and discontinuities in two successive demographic transitions: Spain and Belgium, 1880-2010
cohabitation demographic transition fertility control fertility postponement second demographic transition secularization
2014/11/24
This is a study of how the synergisms between cultural and structural factors, which played a major role during the historical fertility and nuptiality transition (first demographic transition or FDT)...
Effect of discontinuities in Kohn-Sham-based chemical reactivity theory
Effect of discontinuities Kohn-Sham-based chemical reactivity theory Fukui function
2012/2/29
We provide a new derivation of a formula for the Fukui function of density-functional chemical reactivity theory which incorporates the discontinuities in the Kohn-Sham reference system. Orbital relax...
Integrating strong and weak discontinuities without integration subcells and example applications in an XFEM/GFEM framework
Schwarz Christoffel conformal mapping numerical integration extended finite element method quadrature generalized finite element method
2011/9/20
Abstract: Partition of unity methods, such as the extended finite element method (XFEM) allow discontinuities to be simulated independently of the mesh [1]. This eliminates the need for the mesh to be...
On ringing effects near jump discontinuities for periodic solutions to dispersive partial differential equations
ringing effect dispersive equations weak solutions periodic boundary conditions Diophantine approximations Weyl shift method
2011/8/30
Abstract: We consider weak solutions to dispersive partial differential equations with periodic boundary conditions and initial data with jump discontinuities. These are already known to be continuous...

2010/12/10
Due to the limited cell resolution in the representation of flow variables, a piecewise continuous initial reconstruction with discontinuous jump at a cell interface is usually used in modern computat...
Particle acceleration in tangential discontinuities by lower hybrid waves
Particle acceleration tangential discontinuities lower hybrid waves
2009/11/12
We consider the role that the lower-hybrid wave turbulence plays in providing the necessary resistivity at collisionless reconnection sights. The mechanism for generating the waves is considered to be...
Model for vortex turbulence with discontinuities in the solar wind
vortex turbulence discontinuities in the solar wind
2009/11/12
A model of vortex with embedded discontinuities in plasma flow is developed in the framework of ideal MHD in a low b plasma. Vortex structures are considered as a result of 2-D evolution of nonlinear ...
Theory and observation of double discontinuities
Theory observation double discontinuities
2009/11/11
Recent research using high-resolution magnetic field data to examine the interior structures of MHD shocks in interplanetary space and in the magnetotail led to a surprising discovery that a slow-mode...
