USING LATTICE TOPOLOGY INFORMATION TO INVESTIGATE PERSISTENT SCATTERERS AT FACADES IN URBAN AREAS
High resolution SAR Urban Pattern Data Fusion
2014/4/24
Modern spaceborne SAR sensors like TerraSAR-X offer ground resolution of up to one meter in range and azimuth direction. Buildings, roads, bridges, and other man-made structures appear in such data of...
Areas of triangles and Beck's theorem in planes over finite fields
Areas of triangles Beck's theorem planes over finite fields Combinatorics
2012/5/9
It is shown that any subset $E$ of a plane over a finite field $\F_q$, of cardinality $|E|>q$ determines not less than $\frac{q-1}{2}$ distinct areas of triangles, moreover once can find such triangle...
Heavy tailed priors: an alternative to non-informative priors in the estimation of proportions on small areas
Survey Sampling Exponential Family Objective Robust Priors Small Areas Estimation
2011/10/8
Abstract: We explore the Cauchy and a new heavy tailed (Fuquene, Perez and Pericchi (2011)) priors to estimate proportions on small areas. Hierarchical models and the Binomial likelihood in the expone...
Enumeration of closed random walks in the square lattice according to their areas
Enumeration of closed random square lattice
2011/2/22
We study the area distribution of closed walks of length n, begin-ning and ending at the origin. The concept of area of a walk in the square lattice is generalized and the usefulness of the new concep...
Generalized L/'evy Stochastic Areas and Selfdecomposability
Bessel functions I and J L´ evy’s stochas-tic areas selfdecomposability property
2010/12/8
We show that a conditional characteristic function of gener-alized L´evy stochastic areas can be viewed as a product a selfdecomposable distribution (i.e., L´evy class L distribution) and ...
Improved Zonal Method Predictions in a Rectangular Furnace by Smoothing the Exchange Areas
Zone method exchange areas smoothing methods rectangular enclosure
2009/10/9
A numerical study was conducted by the means of the Hottel’s zone method based on the concept of the exchange areas associated with the weighted sum of grey gases model (WSGG model). 2D computational ...
