This paper introduces orthogonal vector field visualization on 2D manifolds: a representation by lines that are perpendicular to the input vector field. Line patterns are generated by line integral convolution (LIC). This visualization is combined with animation based on motion along the vector field. This decoupling of the line direction from the direction of animation allows us to choose the ...

We have recently developed a wide-field photon-counting detector having high-temporal and high-spatial resolutions and capable of high-throughput (the H33D detector). Its design is based on a 25 mm diameter multi-alkali photocathode producing one photo electron per detected photon, which are then multiplied up to 107 times by a 3-microchannel plate stack. The resulting electron cloud is proximi...

In this study, the possibility of on-line monitoring an ultra-high-energy (UHE) beam 150 GeV/n lead (208Pb) ions using a liquid-filled ionization chamber array (OCTAVIUS 1000SRS, PTW Freiburg, Germany) is evaluated. The applicability has been tested for investigated beam, where adequate adjustments have made measurements under very low fluxes 102 to 104 / cm2/s. results compared obtained standa...

A 14 m long beam line dedicated to study very small scattering angles in ion-molecule collisions has been set up in the University of Toledo Heavy Ion Accelerator (THIA) Laboratory. Together with position sensitive detectors for both the projectile and the recoil particles’ detection, the beam line can be used to measure the projectile forward scattering angles of up to 2.5 milliradians (mrad) ...

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...

A method for separation and purification of plant hormones auxin and abscisic acid based on mixed mode reversed-phase anion-exchange solid phase extraction and two-dimensional HPLC was developed. Two-dimensional HPLC in "heart cutting" mode was very efficient in the purification of these two hormones. Its purification power is high enough to allow reliable on-line quantification of both hormone...

The use of a microcalorimeter X-ray detector with a transition edge sensor in an electron probe to perform quantitative analysis is reported. Two bulk samples of multielement glasses that have been previously characterized by chemical methods for use as standard reference materials were analyzed. The spectra were analyzed against standards using three different correction schemes. In one of the...
