Assessment of the reservoir structure and determination of theinsitu stress direction arenecessary in oil production optimization andfield development. Today, the application of reservoir software and Image logsplay a central role in resolving this problem. Electricand ultrasonic imaging tools record vast amounts of high-resolution data within the borehole wall. This enables the geoscientists t...

In this study, we explore several new characteristics of a static anisotropic hybrid star with strange quark matter (SQM) and ordinary baryonic (OBM) distribution. Here, use the MIT bag model equation state to connect density pressure SQM inside stars, whereas linear $p_r =\alpha \rho-\beta$ connects radial caused by matter. The stellar was developed under background $f(Q)$ gravity using quadra...

The interface shape separating a gas layer within a superhydrophobic surface consisting of a square lattice of posts from a pressurized liquid above the surface is computed numerically. The interface shape is described by a constant mean curvature surface that satisfies the Young-Laplace equation with the three-phase gas-liquid-solid contact line assumed pinned at the post outer edge. The numer...

Previously formulated scaling laws relating acoustic waveforms in boreholes to frequency, tool size and borehole diameter were investigated by repeated logging of the same test interval with different frequencies, and by logging adjacent boreholes of different diameters with the same logging system. Acoustic source frequency bands were centered on approximately 15, 20 and 34 kilohertz. Borehole...

W. H. You, D. Y. Kwon, S. K. Ko Refrigerator Design, Home Appliances Business Samsung Electronics, Suwon, Korea A suction valve is a very important element in reciprocating compressor. And because of the shape of the reed valve its reliability is taken up a subject for discussion and sometimes it is main source of bad product. Because the reliability of the suction valve is directly related to ...
