Two-dimensional quantum-spin-1/2 XXZ magnet in zero magnetic field: Global thermodynamics from renormalisation group theory
(Taylor & Francis Ltd, 2019)
Phase diagram, critical properties and thermodynamic functions of the two-dimensional field-free quantum-spin-1/2 XXZ model has been calculated globally using a numerical renormalisation group theory. The nearest-neighbour ...
Cohomological dimension and top local cohomology modules
(Rocky Mountain Mathematics Consortium, 2019)
Let R be a Noetherian ring, I an ideal of R and M an R-module. In this paper, we first determine a condition under which a given integer t is a lower bound for the cohomological dimension cd(I,M), and use this to conclude ...
Single fed UWB sierpinski fractal monopole antenna array
(Institute of Electrical and Electronics Engineers Inc., 2019)
In this work, single fed uniformly spaced seven elements mod-3 Sierpinski gasket antenna array is designed using CST MWS (Computer Simulation Technology Microwave Studio). The designed antenna array is fed by an N type ...
Combinations of Multiple Adaptive Lattice Filters in Sparse Cognitive Radio Channel Identification
(IEEE, 2019)
Sparsity awareness feature has been introduced into the a priori recursive least squares (RLS) lattice algorithm by regularizing the RLS cost function with the addition of l(1)-norm constraint penalty term. The newly ...
