Optimizing Service Areas in 6G mmWave/THz Systems with Dual Blockage and Micromobility
Mathematics, 2023 The modern 5G millimeter wave (mmWave) New Radio (NR) systems as well as future terahertz (THz) radio access technologies (RAT) will heavily rely on beamforming to combat the excessive path losses.

Branching Random Walks with One Particle Generation Center and Possible Absorption at Every Point
Mathematics, 2023 We consider a new model of a branching random walk on a multidimensional lattice with continuous time and one source of particle reproduction and death, as well as an infinite number of sources in which, in addition to the walk, only the absorption of ...

Generalised block bootstrap and its use in meteorology [PDF]
Advances in Statistical Climatology, Meteorology and Oceanography, 2017 In an earlier paper, Rakonczai et al.(2014) emphasised the importance of investigating the effective sample size in case of autocorrelated data. The simulations were based on the block bootstrap methodology.

Propagation Model for Ground-to-Aircraft Communications in the Terahertz Band with Cloud Impairments
Energies, 2022 By operating over a large bandwidth, the terahertz (THz) frequency band (0.3–3 THz) promises to deliver extremely high data rates. While the use of this band in cellular communications systems is not expected to happen within the next decade, various ...

The Quality of Reserve Risk Calculation Models under Solvency II and IFRS 17
Risks, 2022 We analyse four stochastic claims reserving methods in terms of their capability to estimate reserve risk and how successful they are at predicting distributions and VaRs of claim developments in particular.
