Turbulent wind thrust control to reduce pitch motion of floating wind platforms with improved rotor operation
For the dynamic analysis of floating offshore wind turbines (FOWTs) in realistic operating environment, this paper develops a coupled aero-hydro-mooring-servo model applicable to turbulent wind and irregular sea states with high computational efficiency. A modified rotor control strategy with platform motion feedback is proposed with a novel gain-scheduling technique to mitigate the negative damping effect on platform motions and decouple the rotor dynamics from the platform dynamics for better…

In melancholy, the spirits are carried away by an agitation, but a weak agitation that lacks power or violence, a sort of impotent upset that follows neither a particular path nor the aperta opercula [open ways], but traverses the cerebral matter constantly creating new pores. Yet the spirits do not wander far on the new paths they create, and their agitation dies down rapidly, as their strength is quickly spent and motion comes to a halt: ‘non longe perveniunt’ [they do not reach far]. A trouble of this nature, common to all delirium, does not have the power to produce on the surface of the body the violent movements or the cries to be observed in mania and frenzy. Melancholy never attains frenzy; it is a madness always at the limits of its own impotence. That paradox is explained by the secret alterations in the spirits. Ordinarily, they travel with the speed and instantaneous transparency of rays of light, but in melancholy they become weighed down with night, becoming ‘obscure, thick and dark’, and the images of things that they bring before consciousness are ‘in a shadow, or covered with darkness’. As a result they move more slowly, and are more like a dark, chemical vapour than pure light. This chemical vapour is acid in nature, rather than sulphurous or alcoholic, for in acid vapours the particles are mobile and incapable of repose, but their activity is weak and without consequence. When they are distilled, all that remains in the still is a kind of insipid phlegm. Acid vapours, therefore, are taken to have the same properties as melancholy, whereas alcoholic vapours, which are always ready to burst into flames, are more related to frenzy, and sulphurous vapours bring on mania, as they are agitated by continuous, violent movement. If the ‘formal reason and causes’ of melancholy were to be sought, it made sense to look for them in the vapours that rose up from the blood to the head, and which had degenerated into ‘an acetous or sharp distillation’. A cursory glance seems to indicate that a melancholy of spirits and a whole chemistry of humours lies behind Willis’ analyses, but in fact his guiding principle mostly reflects the immediate qualities of the melancholic illness: an impotent disorder, and the shadow that comes over the spirit with an acrid acidity that slowly corrodes the heart and the mind. The chemistry of acids is not an explanation of the symptoms, but a qualitative option: a whole phenomenology of melancholic experience.

SFR va vendre des tours télécoms pour réduire sa dette
Le groupe de Patrick Drahi et son concurrent Bouygues Telecom sont en passe de céder leurs 3 700 sites d’antennes de téléphonie mobile à l’américain Phoenix Tower. Cette vente doit permettre à SFR de diminuer de près 500 millions d’euros sa dette colossale.

I have notice that around here USPS mailboxes have been modified so that they only have a rather thin slot for the insertion of thin envelopes.
No more pulling open a flap on the mailbox and mailing things like ink-jet recycling envelopes or USB flash drives. For that you have to go to an actual physical post office and wait in line for a clerk.
We've been deJoyed again (even after he is gone his is the gift that keeps on taking.)

RadarQA: Multi-modal Quality Analysis of Weather Radar Forecasts
Quality analysis of weather forecasts is an essential topic in meteorology. Although traditional score-based evaluation metrics can quantify certain forecast errors, they are still far from meteorological experts in terms of descriptive capability, interpretability, and understanding of dynamic evolution. With the rapid development of Multi-modal Large Language Models (MLLMs), these models become potential tools to overcome the above challenges. In this work, we introduce an MLLM-based weather …

Milliarcsecond astrometric oscillations in AGN as a precursor of multi-messaging gravitational wave events
The existence of supermassive black hole binaries (SMBHBs) is predicted by various cosmological and evolutionary scenarios for active galactic nuclei. These objects are considered as contributors into the gravitational wave (GW) background and emitters of discrete GW bursts. Yet, SMBHBs remain a rather elusive class of extragalactic objects. Previously we have identified the quasar J2102+6015 as potential SMBHB system based on its oscillating astrometric pattern. We analysed the available VLBI …

When I heard the news that the US bombed Iran. I had to remind myself of what I witnessed this past week - millions of people turned out for #NoKings. Three retiree women in a coffee shop planning their resistance. And these fiber art designs in Lanesboro, MN I saw this weekend. (Shout out to Driftless Fiber Arts) Not the kind of town where you'd expect to see resistance art or pride parad…
