Future applications of millimeter waves (mmWaves) in vehicular scenarios ask for the characterization of the timevariant wideband mmWave channel. For this contribution, we manufactured and measured a proof of concept circuitry intended to receive mmWave signals repeatably at velocities of up to 50 meters per second (=180km/h=112mph). Our design is based on a rotating arm, spinning a small anten...

This article presents a comparative analysis of the properties cotton yarn spun on aerodynamic compact spinning and open-end rotor systems. Yarn samples with linear density 50 Tex, 37 30 25 20 Tex were both systems using same finisher drawn sliver medium staple which produced by specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, tensile behavior (stre...

We study the properties of soliton solutions in an analog of the Skyrme model in 2+1 dimensions whose Lagrangian contains the Skyrme term and the mass term, but no usual kinetic term. The model admits a symmetry under area preserving diffeomorphisms. We solve the dynamical equations of motion analytically for the case of spinning isolated baryon type solitons. We take fully into account the ind...

We study a possibility for pseudoclassical description of a spinning particle in external electromagnetic and torsion fields. To this end we depart from the Dirac equation in such a background and derive a path integral representation for the corresponding propagator. An effective action which appears in the representation is interpreted as a pseudoclassical action for the spinning particle. It...

Dragline silk is the most prominent amongst spider silks and comprises two types of major ampullate spidroins (MaSp) differing in their proline content. In the natural spinning process, the conversion of soluble MaSp into a tough fiber is, amongst other factors, triggered by dimerization and conformational switching of their helical amino-terminal domains (NRN). Both processes are induced by pr...

Although mule spinning has been used in the cotton and wool industries for about two centuries, the *earliest recorded cases of mule spinners' cancer were not reported until the end of the nineteenth century. From then on the number of cases rapidly increased. Evidence accumulated which strongly suggested that the mineral oil used to lubricate the mule spindles was the cause. It is remarkable t...

In this work we give a global-in-time existence and uniqueness proof for solutions of the isothermal equations of fiber spinning. Fiber spinning is a widely used manufacturing process for the production of long thin filaments. In this process a highly viscous fluid is withdrawn from a reservoir and stretched to form a long fiber. The equations modeling fiber spinning are essentially based on cr...
