The grid revisted

Discrete Mathematics, 1993
Diese Arbeit bezieht sich auf die Arbeit von \textit{P. Erdős} [Ann. Math. Mon. 53, 248-250 (1946; Zbl 0060.34805)]. Die originale Fragestellung wurde hier in einer verallgemeinerten Form aufgeschrieben: Sei eine Punktmenge \(P=\{p_1,p_2,\ldots,p_n\}\) in einem metrischen Raum \(M\supseteq P\) gegeben.

Ionic Liquid‐Based Reversible Metal Electrodeposition for Adaptive Radiative Thermoregulation Under Extreme Environments

Advanced Functional Materials, EarlyView.
A wideband tunable electrochromic device with dynamic thermal emissivity control is demonstrated. The system enables adaptive heat regulation via electrochemically modulated silver deposition, achieving efficient cooling and heating states. The flexible design ensures mechanical robustness under bending conditions, making it promising for portable and ...

Electricity Generation From Ambient Water Evaporation in the Absence of Sunlight via PVA‐Based Porous Hydrogels

Advanced Functional Materials, EarlyView.
In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Proxy dynamic delegation in grid gateway

, 2011
Nowadays one of the main obstacles the research comes up against is the difficulty in accessing the required computational resources. Grid is able to offer the user a wide set of resources, even if they are often too hard to exploit for non expert end ...

Influence of Layering and Curie Temperature Uncertainty on the Performance of Multilayer Active Magnetic Regenerators

Advanced Functional Materials, EarlyView.
This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.

The Grid Observatory

2011 11th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing, 2011
The goal of the Grid Observatory project (GO) is to contribute to an experimental theory of large grid systems by integrating the collection of data on the behaviour of the flagship European Grid Infrastructure (EGI) and its users, the development of models, and an ontology for the domain knowledge.
