A quantum scar is a wave function which displays an high intensity in the region of a classical unstable periodic orbit. Saddle scar are states related to the unstable harmonic motions along the stable manifold of a saddle point of the potential. Using a semiclassical method it is shown that, independently of the overall structure of the potential, the local dynamics of the saddle point is suff...

Measurement of the beam quadrupole moment at several locations can be used to reconstruct the beam envelope and emittance parameters. The measurements can be performed in a non-intercepting way using a set of quadrupole-mode cavities. We present a cavity design with an optimized quadrupole moment shunt impedance. The cavity properties can be characterized using a wire test method to insure symm...

The compression of ceramic powders requires the addition of organic materials to insure tablet cohesion. For the compaction of formulated ceramic powders it is necessary to supply them energy. As a function of the formulation of ceramic powders, one can measure the specific energy acquired during the tablet compression. Recently, a technique used in powder metallurgy, High Velocity Compaction (...

By MARY C. MoRGAN AND JEAN J. SZAFIP A QUANTITATIVE method for the separation of morphologically intact ftinctional platelets from whole blood is not available at the present time. Methods have been described which use differential centrifugation or sedimentation, with and without washing procedures. The prolonged manipulations required with these procedures to insure total recovery leads to pl...

of the combined addressing because of the large number of unconditional transfers that must be entered to insure the correct function of the automaton [4, 5, 7, 8]. The present method is based on dividing the MI into subsets to minimize the MI numbers. The Combined Microinstructions (CMI) are used in MicroProgram Memory (MPM). The control words can be stored, with the following format, in vario...

Spatial topology rule is the primary method to insure the consistency and validity of spatial topology relation in GIS software. Topology rule can be divided into three categories according to geographic entity’s geometric shape: point topology rule, line topology rule and polygon topology rule. At first, this paper summarizes the various linear geographic entities’ topological relations which ...

Vacuum circuit breaker becomes more and more complicated, integrated, high-speed and intellectualized. To insure vacuum circuit breaker in its good conditions, the function of fault diagnosis gets more important than before in the process of repairing. This paper is addressed a modelbased fault detection framework for vacuum circuit breaker by trip coil analysis. At first, the electromagnetic m...
