Efficient MDS Diffusion Layers Through Decomposition of Matrices
Diffusion layer MDS matrix Symmetric cipher
2015/12/24
Diffusion layers are critical components of symmetric ciphers. MDS matrices are diffusion layers of maximal branch number which have been used in various symmetric ciphers. In this article, we examine...
Decomposition of Airborne Laser Scanning Waveform Data Based on EM Algorithm
LIDAR Waveform-digitizing Analysis of waveform Filter Smooth Gaussian decomposition DSM
2015/11/20
Data storage capacity and high processing speed available today has made it possible to digitally sample and store the entire reflected waveform of Small-Footprint Airborne Lidar (light detection and ...
A PROOF OF THE KAZHDAN-LUSZTIG PURITY THEOREM VIA THE DECOMPOSITION THEOREM OF BBD
KAZHDAN-LUSZTIG DECOMPOSITION
2015/9/29
The ˉrst ingredient is quite deep, and we will not say anything much about its
proof, using it simply as a \black box". The second ingredient is elementary, and
we take this opportunity to present a...
GENERALISATION OF 3D BUILDING MODELS BY CELL DECOMPOSITION AND PRIMITIVE INSTANCING
Generalization Algorithms Building Three-dimensional GIS Visualization
2015/9/28
The article presents a cartographic generalisation approach for 3D building models with regard to the thematic visualisation of urban
landscapes. Based on our earlier work to utilise approximating p...
By a classifiable theory we shall mean a theory which is superstable, without
the dimensional order property, which has prime models over pairs. In order
to define what we mean by unique decompositi...
We describe the application of the graph-theoretic property known as treewidth to the problem of
finding efficient parsing algorithms. This method, similar to the junction tree algorithm ...
Mapping litter decomposition by remote-detected indicators
decomposition rates hyper-spectral image NDVI co-kriging
2015/9/7
Leaf litter decomposition is a key process for the functioning of natural ecosystems. An important limiting factor for this process is detritus availability, which we have estimated by remote sensed i...
CELL DECOMPOSITION FOR THE GENERATION OF BUILDING MODELS AT MULTIPLE SCALES
CAD Data Structures Representation Three-dimensional Point Cloud Urban LIDAR Modelling
2015/8/31
Existing tools for 3D building reconstruction usually apply approaches, which are either based on constructive solid geometry (CSG) or boundary representation (B-Rep). After a brief discussion of thei...
Modal decomposition of magnetic maps: the case of Cape Roberts aeromagnetic survey, Antarctica
Magnetic mapping Digital Enhancement Eigenvalues HRAM Antarctic Magnetic Surveys
2015/8/28
This paper proposes a digital enhancement tool for magnetic anomaly maps. The magnetic anomaly map is decomposed by means of Eigenvalue Decomposition into a number of orthogonal bases. The dataset is ...

Bayesian approach to magnetotelluric tensor decomposition
Magnetotelluric regional composite electric model the underlying structure of the bayesian stochastic method
2015/8/28
Magnetotelluric directional analysis and impedance tensor decomposition are basic tools to validate a local/regional composite electrical model of the underlying structure. Bayesian stochastic methods...
Application of empirical mode decomposition to very low frequency signals for identification of seismic-ionospheric precursor phenomena
Earthquake Precursor Phenomena Empirical Mode Decomposition
2015/8/24
This study investigates the application of empirical mode decomposition to signals from very low frequency transmitters in Europe that were received in Thessaloniki, Greece, to provide a method for de...
Uncertainty Principles and Ideal Atomic Decomposition

Suppose a discrete-time signal S(t), 0 tposition of atoms taken
from a combined time/frequency dictionary made of spike sequences 1ft= g and sinu- soids expf2iwt=N)=p

When Does Non-Negative Matrix Factorization Give a Correct Decomposition into Parts?
Non-Negative Matrix Factorization Parts
2015/8/21
We interpret non-negative matrix factorization geometrically, as the
problem of finding a simplicial cone which contains a cloud of data
points and which is contained in the positive orthant.
A penalized matrix decomposition, with applications to sparse principal components and canonical correlation analysis
Canonical correlation analysis DNA copy number Integrative genomic analysis L1 Matrix decomposition Principal component analysis Sparse principal component analysis SVD.
2015/8/21
We present a penalized matrix decomposition (PMD), a new framework for computing a rank-K approximation for a matrix. We approximate the matrix X as X ˆ = k K=1 dkukvk T , where dk, uk, and vk m...
