Radiative Shock-Induced Collapse of Intergalactic Clouds

open access: yes, 2003
Accumulating observational evidence for a number of radio galaxies suggests an association between their jets and regions of active star formation. The standard picture is that shocks generated by the jet propagate through an inhomogeneous medium and ...

Two Clusters with Radio-quiet Cooling Cores

open access: yes, 2005
Radio lobes inflated by active galactic nuclei at the centers of clusters are a promising candidate for halting condensation in clusters with short central cooling times because they are common in such clusters.

A method for localizing energy dissipation in blazars using Fermi variability [PDF]

open access: yes, 2012
The distance of the Fermi-detected blazar gamma-ray emission site from the supermassive black hole is a matter of active debate. Here we present a method for testing if the GeV emission of powerful blazars is produced within the sub-pc scale broad line ...

Fabrication of active cooling e-Textiles [PDF]

open access: yesTextile Coloration and Finishing, 2008
Cooling function is definitely one of the most desirable attribute of clothing. In spite of the recent progress on phase changing material(PCM) research, the final products with sufficient amount of cooling capability have not yet to be developed in market.

Neural Network-Based Active Cooling System With IoT Monitoring and Control for LCPV Silicon Solar Cells

open access: yesIEEE Access, 2023
One of the methods of increasing output power of solar cells is increasing the concentration ratio using lenses and mirrors. Due to the temperature increase of silicon solar cells with concentrating lenses the system must be provided with an active ...

High-throughput screening of room temperature active Peltier cooling materials in Heusler compounds

open access: yesnpj Computational Materials, 2022
Active Peltier cooling enables Peltier heat transfer in addition to the traditional Fourier thermal conductance, which is useful in some special applications, such as the microthermostats.

Study on Phase-Shift Mechanism and Kriging-Based Global Optimization of the Active Displacer Pulse Tube Refrigerators

open access: yesEnergies, 2023
Pulse tube refrigerators are widely used in certain special fields, such as aerospace, due to their unique advantages. Compared to a conventional phase shifter, the active displacer helps to achieve a higher cooling efficiency for pulse tube ...

Cooling of Nanomechanical Resonator Based on Periodical Coupling to Cooper Pair Box

open access: yes, 2005
We propose and study an active cooling mechanism for the nanomechanical resonator (NAMR) based on periodical coupling to a Cooper pair box (CPB), which is implemented by a designed series of magnetic flux pluses threading through the CPB.
