Pilot-to-Data Power Ratio in RIS-Assisted Multiantenna Communication
The optimization of the \gls{pdpr} is a recourse that helps wireless systems to acquire channel state information while minimizing the pilot overhead. While the optimization of the \gls{pdpr} in cellular networks has been studied extensively, the effect of the \gls{pdpr} in \gls{ris}-assisted networks has hardly been examined. This paper tackles this optimization when the communication is assisted by a RIS whose phase shifts are adjusted on the basis of the statistics of the channels. For a set…

Was Google da wieder vorhat, lässt mich noch mehr über ein neues Smartphone mit #eOS nachdenken.
@… wie ist es mit eurer GLS-Banking-App, funktioniert die unter /e/OS?

Ich habe via Amazon bei einem deutschen Händler 6 Flaschen Sirup bestellt.
Händler schickte das falsche Produkt.
Zurückgeschickt in der selben Verpackung.
Nun schreibt mir GLS einen Brief, dass sie es nicht zustellen konnten, weil eine Flasche kaputtgegangen ist. Und wollen eine Verfügung.
WTH? Wie soll ich eine Verfügung erteilen? Bedeutet das in D was anderes als in CH?

A Corrective Frequency-Constrained Unit Commitment with Data-driven Estimation of Optimal UFLS in Island Power Systems
This paper presents a novel corrective \gls{fcuc} formulation for island power systems by implementing data-driven constraint learning to estimate the optimal \gls{ufls}. The Tobit model is presented to estimate the optimal amount of \gls{ufls} using the initial rate of change of frequency. The proposed formulation enables co-optimizing operation costs and \gls{ufls}. The aim is to account for optimal \gls{ufls} occurrences during operation planning, without increasing them. This would potentia…

A Comparative Study on Frequency-Constrained Unit Commitment Approaches in Island Power Systems
The increasing penetration of renewable energy sources reduces rotating inertia and even frequency control capacity, affecting frequency stability. This challenge is significant in \gls{ips} that already suffer from low inertia and frequency control capacity. This paper presents a comparative study on different \gls{fcuc} formulations applied to \gls{ips}. Then, by considering under-frequency load shedding as a significant measure of frequency stability in \gls{ips}, two indices are presented t…

Destruction of "Peas in a Pod?" A Candidate Multi-planet System Around the Nearby, Bright Star, HD208487
We re-investigate the HD208487 system to test the reality of the proposed HD208487c world. We also search for additional companions using applied Bayesian statistics and 15+ years of new RV data from the HARPS and the PFS instruments that were taken post-discovery of HD208487b. The RV data was analyzed with GLS Periodograms, followed by Bayesian analysis using the EMPEROR code. We scrutinised various stellar activity indices to search for any corresponding peaks in the power spectra, correlat…

Space-O-RAN: Enabling Intelligent, Open, and Interoperable Non Terrestrial Networks in 6G
Satellite networks are rapidly evolving, yet most \glspl{ntn} remain isolated from terrestrial orchestration frameworks. Their control architectures are typically monolithic and static, limiting their adaptability to dynamic traffic, topology changes, and mission requirements. These constraints lead to inefficient spectrum use and underutilized network capacity. Although \gls{ai} promises automation, its deployment in orbit is limited by computing, energy, and connectivity limitations. This p…
