Quantum squeezing is an important resource in modern quantum technologies, such as precision measurement and continuous-variable information processing. The generation of squeezed states mechanical modes a significant task cavity optomechanics. Motivated by recent interest multimode optomechanics, it becomes interesting topic to create quadrature multiple resonators. However, the multiple-degen...

In this paper, the effects of carbon nanotube (CNT) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by CNTs are investigated based on a mesh-free method. The used nanocomposites are made of the straight CNTs that are embedded in an isotropic polymer as matrix. The straight CNTs are oriented, randomly or aligned or local aggregated int...

Superior nanomaterials have been developed and applied to many fields, and improved characteristic of nanomaterials have been studied. Measurement of the mechanical properties for nanomaterials is important to ensure the reliability and predict the service life times of products containing nanomaterials. However, it is challenging to measure the mechanical properties of nanomaterials due to the...

Precision measurement of nonlinear observables is an important goal in all facets of quantum optics. This allows measurement-based non-classical state preparation, which has been applied to great success in various physical systems, and provides a route for quantum information processing with otherwise linear interactions. In cavity optomechanics much progress has been made using linear interac...

this study evaluated the use of the solar dryer at esfahan agricultural research center for drying prunes. a factorial experiment was carried using a randomized complete block design with four replications. the four methods used to accelerate prune drying were: control group (no treatment), mechanical perforation at one week of drying, blanching, submersion in australian cold dip method. the dr...

in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...

-” -The mechanical equipment for measuring and aligning (or fiducializing) magnets is described by reference to devices designed and built by a number of laboratories. Some of these are now available commercially. The descriptions are supplemented by a list of representative sources of hardware.
