Imprese e contratti di assunzione: prime analisi da Netlabor
No full textL'iscrizione alle liste dei Centri per l'impiego, ex Uffici di Collocamento, di coloro che cercano lavoro nel settore dipendente privato dà origine ad un archivio amministrativo che contiene informazioni sui lavoratori e sulle loro storie lavorative. L'archivio è arricchito dalle informazioni fornite ai Centri per l'impiego da parte delle aziende nell'assolvere l'obbligo di comunicare ogni assunzione e, in generale, ogni modifica di rapporto di lavoro. La finalità di questo saggio è descrivere le potenzialità di tale archivio, denominato Netlabor, allo scopo di analizzare il mercato del lavoro italiano, in particolare a livello locale. A scopo di esempio, si presentano alcune analisi esplorative su di un argomento al momento alquanto dibattuto nel nostro Paese: l'utilizzo delle varie forme contrattuali da parte delle imprese
The effects of free-stream turbulence on the performance of a model wind turbine
No full textFree-stream turbulence characteristics play an important role in the mechanisms of power harvesting for wind turbines. Acquisitions of power and thrust from a model wind turbine of diameter 0.18 m have been carried out in a wind tunnel for a wide range of turbulent base flows, with varying free-stream turbulence intensity in the range between 3% and 16% and integral timescale spanning from 0.1 to 10 times the turbine rotation period. The results demonstrate that power is significantly affected by both the inflow turbulence scales and its intensity, while thrust is scarcely affected by free-stream turbulence. Fluctuations in the generated torques are also measured, with their behavior dominated by the free-stream turbulence scale, and only moderately affected by turbulence intensity. The frequency response of thrust fluctuations has been measured for a selected subset of operating conditions, demonstrating that the turbine thrust is unaffected by high-frequency components in the inflow. Conclusions are drawn on the necessity to match both turbulence intensity and base flow frequency content in wind tunnel studies if realistic results are to be obtained from small-scale studies.</p

Synchronizing network systems in the presence of limited resources via edge snapping
No full textIn this work, we propose a multilayer control protocol for the synchronization of network dynamical systems under limited resources. In addition to the layer where the interactions of the system take place, i.e., the backbone network, we propose a second, adaptive layer, where the edges are added or removed according to the edge snapping mechanism. Different from classic edge snapping, the inputs to the edge dynamics are modified to cap the number of edges that can be activated. After studying the local stability of the overall network dynamics, we illustrate the effectiveness of the approach on a network of Rössler oscillators and then show its robustness in a more general setting, exemplified with a model of the Italian high-voltage power grid

No full textStability of Synchronization in Simplicial Complexes
No full textNetworks with higher order interactions, relevant to social groups, ecosystems and human brain, require new tools and instruments for their analysis. Gambuzza et al. propose an analytical approach which allows to find conditions for stable synchronization in many-body interaction networks
