In magnetic cataclysmic variables (mCVs), X-ray radiation originates from a shock-heated, multi-temperature plasma in the post-shock region near white dwarf's surface. These X-rays are modified by complex distribution of absorbers pre-shock region. The presence photoionized lines and warm absorber features soft spectra these mCVs suggests that ionized. We developed ionized model zxipab, which i...

Conceptual innovation in mechanical engineering design has been extremely challenging compared to the wide applications of automated design systems in digital circuits. This paper presents an automated methodology for open-ended synthesis of mechanical vibration absorbers based on genetic programming (GP) and bond graphs (GPBG). It is shown that our automated design system can automatically evo...

Spectrally-selective solar absorbers harvest solar energy in the form of heat. Solar absorbers using cermet-based coatings demonstrate a high absorptance of the solar spectrum and a low emittance in the infrared (IR) regime. Extensive work has been done to optimize cermet-based solar absorbers to achieve high performance by exploring different cermet (ceramic-metal composite) materials and film...

We observe with Keck/HIRES the z ≈ 2.5 QSO triplet 1623+27 in order to explore on the scale of a Megaparsec the spatial clustering of C IV absorbers between adjacent sightlines. We find this signal to be significantly weaker than the clustering in velocity on corresponding scales along single sightlines, assuming that the relative velocity of absorbers is dominated by the Hubble flow. This indi...

To design a high-quality vehicle shock absorber, the internal structure of piston assembly absorber is analyzed in this study. Using fluid–solid coupling method, high-precision flow grid model and solid finite element stacked valve are built analyzed. A bidirectional method proposed, which can be adopted to simulate analyze dynamic nonlinear response characteristics for slice Workbench software...

We present an imaging and spectroscopic survey of galaxies in fields around QSOs HE 0226−4110, PKS 0405−123, and PG 1216+069. The fields are selected to have ultraviolet echelle spectra available, which uncover 195 Lyα absorbers and 13 OVI absorbers along the three sightlines. We obtain robust redshifts for 1104 galaxies of rest-frame absolute magnitude MR −5log h . −16 and at projected physica...

Any alternating electric power supply is always characterized by three reference quantities, which are voltage, and frequency.

We have developed computer program MATLAB to simu...

Three-dimensional model of closed cell foam based on idealized geometry is developed and used to study its response under quasi-static compression, impact shock loading. Foams with a wide range densities corresponding morphologies are modeled. Geometry the unit cells construct 3-D experimentally measured sizes wall thicknesses. The numerical validated against determined stress vs. strain relati...
