Abstract The mechanical efficiency of rotating machinery improves as drag power losses in bearings reduce; hence, an operation mode that reduces the supplied flow brings immediate benefits. paper presents measurements static and dynamic load performance conducted with a tilting pad journal bearing configured flooded evacuated, rates from 150% to ∼25% (or lesser) nominal magnitude, proportional ...

We present a tidal model for treating the rotational evolution in general three-body problem with arbitrary viscosities, which all masses are considered to be extended and interactions between pairs taken into account. Based on creep tide theory, we set of differential equations that describes each body, formalism is easily extensible N tidally interacting body problem. apply our case circumbin...

Simulation of fast and slow dynamic behavior of electrical power systems is needed for many industrial applications. The results influence the development of electrical and mechanical components and the design of control elements in power systems. Examples are Mechanical stresses on network elements Control systems of turbines and generators Settings of protective relays Transient stability of ...

To completely eliminate the time delays caused by phasor data compressions for real-time synchrophasor applications, a compression (RSDC) is proposed in this paper. The two-way rotation characteristic and elliptical trajectory of dynamic synchrophasors are introduced first to enhance along with fast solving method fitting equations. RSDC reconstruction then combining interpolation extrapolation...

rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
