Radial stability analysis of the continuous pressure gravastar

, 2012
Radial stability of the continuous pressure gravastar is studied using the conventional Chandrasekhar method. The equation of state for the static gravastar solutions is derived and Einstein equations for small perturbations around the equilibrium are ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Pressure pulsations in power hydraulics systems

Mining Machines, 2020
The paper discusses the problem of pressure pulsation in hydraulic systems. The most important causes of pressure disturbances were discussed, such as: instability of the pump performance, variability of the system load and transient states related to the control of the system. The next part presents the threats caused by pressure fluctuations.

Classical Cepheid Pulsation Models: IX. New Input Physics

, 2003
We constructed several sequences of classical Cepheid envelope models at solar chemical composition ($Y=0.28, Z=0.02$) to investigate the dependence of the pulsation properties predicted by linear and nonlinear hydrodynamical models on input physics.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

Advanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

On the understanding of pulsations in the atmosphere of roAp stars: phase diversity and false nodes

, 2011
Studies based on high-resolution spectroscopic data of rapidly oscillating Ap stars show a surprising diversity of pulsation behavior in the atmospheric layers, pointing, in particular, to the co-existence of running and standing waves.

Experimental research of pulsation pressure and hydrodynamic noise at the bow of underwater vehicle

Xibei Gongye Daxue Xuebao
The design of the bow of the underwater vehicle affects its hydrodynamic performance, and a better design can reduce the direct impact of water on the bow and thus reduce the hydrodynamic noise of the underwater vehicle.
