Analysis on the Empirical Spectral Distribution of Large Sample Covariance Matrix and Applications for Large Antenna Array Processing
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper addresses the asymptotic behavior of a particular type of information-plus-noise-type matrices, where the column and row numbers of the matrices are large and of the same order, while signals have diverged and ...
StructMatrix: large-scale visualization of graphs by means of structure detection and dense matrices
(Institute of Electrical and Electronics Engineers – IEEEAtlantic City, 2015-11)
Given a large-scale graph with millions of nodes and edges, how to reveal macro patterns of interest, like cliques, bi-partite cores, stars, and chains? Furthermore, how to visualize such patterns altogether getting insights ...
Parallel Algorithm for Reduction of Data Processing Time in Big Data
(Institute of Physics Publishing, 2020-01-07)
Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. ...
Compatibility of the large quasar groups with the concordance cosmological model
(2016)
We study the compatibility of large quasar groups with the concordance cosmological model. Large quasar groups are very large spatial associations of quasars in the cosmic web, with sizes of 50-250 h(-1) Mpc. In particular, ...
Large barchanoid dunes in the Amazon River and the rock record: Implications for interpreting large river systems
(Elsevier Science Bv, 2016)
The interpretation of large river deposits from the rock record is hampered by the scarcity of direct observations of active large river systems. That is particularly true for deep-channel environments, where tens of meters ...
Large-S limit of the large-N theory for the triangular antiferromagnet
(American Physical Society, 2019-09)
Large-S and large-N theories (spin value S and spinor component number N) are complementary, and sometimes conflicting, approaches to quantum magnetism. While large-S spin-wave theory captures the correct semiclassical ...
