On the Effect of Tap Changers and Nonlinear Loads on Voltage Stability
On 21 June 2024, a severe incident happened in the South-Eastern part of the Continental European power system. After a voltage collapse, large parts of Albania, Montenegro, Bosnia and Herzegovina as well as Croatia suffered from a blackout [1]. The initial tripping of two transmission lines resulted in a voltage collapse in these countries. Investigations have shown that a) transformers with on-load tap changers (OLTC) and b) nonlinear loads, in particular air conditioning systems, played a si…

Tiling with Three Polygons is Undecidable
We prove that the following problem is co-RE-complete and thus undecidable: given three simple polygons, is there a tiling of the plane where every tile is an isometry of one of the three polygons (either allowing or forbidding reflections)? This result improves on the best previous construction which requires five polygons.

China überschreitet als erstes Land der Welt die Marke von 1.000 GW Solarleistung
Münster – China entwickelt sich immer schneller zum Motor für den globalen Ausbau der erneuerbaren Energien. Allein in den ersten sechs Monaten des Jahres 2025 wurden in China neue Solaranlagen mit einer Leistung von 210 GW (210.000 MW) neu errichtet. Das ist deutlich mehr als die gesamte installierte Solarleistung in den USA mit rund 178 GW (IRENA, 2024); Deutschland liegt Ende letzten Jahres bei 100 GW (MaStR, BNetzA).

KORRIGIERTE GRAFIK FÜR ZU/RÜCKBAU
Jährlicher Zubau und Rückbau von #Balkonsolarleistung in Deutschland mit Stand vom 22.08.2025.
Unplausible Inbetriebnahmedaten von 1900 bis 2017 wurden durch das Registrierungsdatum der #Steckersolaranlage ersetzt.

“An inmate who has pleaded guilty to murdering Robert Pickton in prison last year says he did it for the serial killer's victims.
Martin Charest admitted on Thursday morning to fatally assaulting Pickton with a broken broom handle at the Port-Cartier federal penitentiary in May 2024.
Charest pleaded guilty to first-degree murder during a court appearance in Sept-Îles, Que., northeast of Quebec City.
Pickton was convicted in 2007 of six counts of second-degree murder, but confessed to killing a total of 49 women whom he lured to his pig farm near Vancouver.
A statement of facts read out in court detailed how Charest locked himself into a room with Pickton and assaulted him twice while guards were unable to enter.
Charest told the judge he murdered Pickton after the serial killer had continued to brag about the murders and told other inmates he'd commit more crimes if he was ever released.”

Streamingplattformen haben kaum Schweizer Filme im Angebot. Diese machen weniger als 3% der Filme und rund 2% der Abrufe aus. Dennoch ist ihr Publikum in absoluten Zahlen stark gewachsen: Zwischen 2023 und 2024 gab es 7-mal mehr Abrufe, und dies obschon das Angebot an Schweizer Filmen auf den Streamingplattformen innerhalb eines Jahres um 2% zurückging. Das gesteigerte Interesse fokussiert sich dabei auf einige wenige Grosserfolge.
