We study semi-classically the dynamics of string solitons in the Maldacena-Nuñez background, dual in the infra-red to N=1, d = 4 SYM. For closed string configurations rotating in the S × R space wrapped by the stack of N D-branes we find a behavior that indicates the decoupling of the stringy Kaluza-Klein modes with sufficiently large SO(3) quantum numbers. We show that the spectrum of a pulsat...

The study based on the slab method and FEM simulation is to explore wire rod drawing using rotating die. Constant shear friction assumed at interface between die different conditions such as angular velocity (ω), half angle (α°), frictional factor (m) etc. influence of forming characteristics. Besides, stress occurred has been analyzed realize whether failed or not. axial stress, radial force, ...

In the AdS/CFT correspondence a chiral primary is described by a supergravity solution with mass equaling angular momentum. For AdS3 × S3 we are led to consider three special families of metrics with this property: metrics with conical defects, Aichelburg-Sexl type metrics generated by rotating particles, and metrics generated by giant gravitons. We find that the first two of these are special ...

In this article, a semi-analytical solution is provided to investigate the free vibration characteristics of rotating truncated conical shells surrounded by Winkler–Pasternak type foundation. It assumed that material shell composed epoxy as matrix and graphene nanoplatelets (GPLs) reinforcement dispersed in both thickness length directions shell. The modeled based on first-order shear deformati...

the root pulling force as well as the amount of transferred soil have not been reported quantitatively for various sugar beet types. this study was designed to measure the amounts of transferred soil from farm and estimate the root pulling force among sugar beets populations with different root shapes at harvest time. the experiment was conducted as a split plot with a randomized complete block...

Some AdS$_3 \times M_7$ type IIB vacua have been recently proposed to arise from D3-branes wrapped on a spindle, sphere with conical singularities at the poles. We explicitly construct generalization of these solutions corresponding class electrically charged and rotating supersymmetric black strings in AdS$_5 S^5$ general magnetic fluxes spindle. then perform counting their microstates using C...

Conical Rotary Compressor (CRC) is a screw type Positive Displacement Machine (PDM) consisting of one inner rotor rotating inside an outer rotor. The conical internal meshing rotors with the feature variable pitch and profile have inherent capability to operation at high pressure ratio due built-in volume low leakage. CRC has potential run in various applications such as Heating, Ventilation, A...

The yield criterion of many metallic materials differs from the von Mises criterion. However, available upper bound solutions are almost all restricted to this objective present paper was derive an solution based on a generalized for evaluating extrusion and drawing force, assuming conical die. method conventional used in conjunction with development is necessary, since work function not readil...
