Multi-User Flexible Coordinated Beamforming using Lattice Reduction for Massive MIMO Systems
K. Zu, R. C. de Lamare
The application of precoding algorithms in multi-user massive multiple-input multiple-output (MU-Massive-MIMO) systems is restricted by the dimensionality constraint that the numbe…
On testing single connectedness in directed graphs and some related problems
Martin Dietzfelbinger, Raed Jaberi
Let be a directed graph with vertices and edges. The graph is called singly-connected if for each pair of vertices there is at most one simple pat…
Local formation of nitrogen-vacancy centers in diamond by swift heavy ions
J. Schwartz, S. Aloni, D. F. Ogletree +6
We exposed nitrogen-implanted diamonds to beams of swift uranium and gold ions (~1 GeV) and find that these irradiations lead directly to the formation of nitrogen vacancy (NV) cen…
Counting K_4-Subdivisions
Tillmann Miltzow, Jens M. Schmidt, Mingji Xia
A fundamental theorem in graph theory states that any 3-connected graph contains a subdivision of . As a generalization, we ask for the minimum number of -subdivisions th…
Stochastic Nonlinear Model Predictive Control with Efficient Sample Approximation of Chance Constraints
Stefan Streif, Matthias Karl, Ali Mesbah
This paper presents a stochastic model predictive control approach for nonlinear systems subject to time-invariant probabilistic uncertainties in model parameters and initial condi…
Variational principles for self-adjoint operator functions arising from second-order systems
Birgit Jacob, Matthias Langer, Carsten Trunk
Variational principles are proved for self-adjoint operator functions arising from variational evolution equations of the form \[ \langle\ddot{z}(t),y \rangle + \mathfrak{d}[\dot{z…
