Spatio-Temporal Spectrum Holes and the Secondary User
No full textDSA research must explicitly consider the perspective of secondary users. This paper considers the spatio-temporal properties of spectrum holes as they impact the secondary user’s communications needs. Like Weiss et.al. [1], this paper develops typology of spectrum holes from the point of view of the secondary user. Each type of spectrum hole is analyzed for the kinds of communications requirements that can be supported, illustrated, where possible, existing measurement data. The analysis concludes that a secondary user’s ability to meet their communications need varies considerably. More detailed analysis of the spatio-temporal density of spectrum holes would be necessary to further quantify these conclusions

No full textThis statement made by Congressman Ted Weiss (D - New York) expresses concern regarding the rise in incidents of harassment against opponents of the Marcos regime in the Philippines. Several reported incidents are listed and Weiss stresses the need to protect the right to political protest in the United States
Convergence Behaviour of LMS-Type Algorithms for Adaptive Noise Control in Noisy Doppler Environments (862kB)
No full textThis paper discusses the convergence and tracking behaviour of LMS-type algorithms in a certain type of environment, which is characterised by a Doppler shift in frequency between the two signals available to the algorithm and rapid variations in signal power. We show the linear time-varying characteristics of the underlying system and derive optimum trajectories to which we can compare the adaptation and tracking ability of first order LMS and NLMS adaptive filters. We also present simulations using higher filter orders and real world noise, for which particular emphasis is put on the presence of observation noise. An excursion into the theory of non-stationary convergence and tracking of adaptive algorithms provides justification for the observed behaviour of the algorithms
Multi-Dimensional Weiss Operators
No full textWe present a solution of the Weiss operator family generalized for the case of R(d) and formulate a d-dimensional analogue of the Weiss Theorem. Most importantly, the generalization of the Weiss Theorem allows us to find a subset of null class functions for a partial differential equation with the generalized Weiss operators. We illustrate the significance of our approach through several examples of both linear and non-linear partial differential equations
COVID-19 Vaccination policies in an autocratic context: Belarus vs. Russia
No full textThe paper continues a book chapter devoted to the Belarusian and Russian crisis management during the first months of the pandemic (Weiss 2022). The present chapter examines the second half of 2021 when vaccines were already available in both countries. It is based on data from speeches broadcast on TV, reports by so-called “foreign agents”, i.e. Russian independent investigative agencies, and online news including the official Kremlin site. The main research question focuses on the impact of vaccination on both Lukašenko’s and Putin’s policies: how did their communication strategies change, what was their own stance towards vaccination, and how did they cope with peoples’ reluctance to get vaccinated? The tools to achieve this goal are mainly provided by argumentation theory and impoliteness theory. The comparison is somewhat impeded by Lukašenko being a tacit COVID denier who rejected any compulsive protective measures but nevertheless had to support vaccination. He mercilessly insulted his ministers who tried to impose protective measures on citizens and he tended to conflate online bloggers criticizing his crisis management with his political opponents. Putin backed the vaccination campaign but did not succeed in overcoming the masses’ passive resistance despite a “split-voice” strategy: whereas he officially maintained his image of an unbiased father of the nation, state media such as the TV station “Russia today”, which attacked anti-vaxxers very aggressively, portrayed him as the main decision-maker and ruthless punisher. His publicly pronounced arguments against compulsory vaccination proved very weak
