To solve the problem of water pressure fluctuation caused by the traditional double-acting intensifier, the paper has designed abrasive water-jet cutting machine based on phased intensifier as well as open numerical control system. The structure of cutting machine as well as the hardware structure and working principle of phased intensifier are introduced. The phased intensifier employs a const...

Abstract Totemo in contemporary Japanese is a degree adverb (intensifier). Previous studies have reported that totemo derived from the kakutemo , which means ‘either way’ (and hence bipolar item) classical Japanese. These also became negative polarity item (an modifying words for evaluation), but then shifted to positive and counter-expectation factors played an important role this shift. It ‘s...

Problem. The task of positioning the working mechanism bulldozer in real time is considered. It has been proven that modern road machines control systems combine achievements field GPS satellite and mechatronic means. A competitive analysis showed tests a traditional with intensifier have not conducted before. CRM was solved without fully taking into account diagnostic parameters. Goal. goal to...

For augmented fluoroscopy in the context of minimally invasive EP procedures, a patient-specific model of the atrium segmented from a 3-D volume can be overlaid on fluoroscopic images. This requires a registration between the 3-D model coordinate system and the coordinate system of the C-arm X-ray device. We propose an indirect registration that makes use of surrounding anatomical structures th...

High-speed, gross, alpha autoradiographs can be made if silver-activated zinc sulfide is used as an intensifier in conjunction with high-speed film. The intensifier is interposed between the sample and film. This technique requires about 1/1000 of the exposure time required with Kodak NTB plates. The gross autoradiographs have greater contrast but slightly less resolution than conventional plates.

Explicit expressions are given for the relative variance of the output screen of X-ray image intensifiers, and for detection quantum efficiency as a function of the technical features of the intensifier. The analysis takes into account all conversion stages and physical processes inside the image intensifier and includes a special treatment of scintillation. The results are analysed numerically...

For many years electronics has been engaged in the problems of amplifying very weak currents and voltages. In rece~t years, partly owing to the stimulus of teleuision, a new branch of,electronies, that"'is, the intensification. of light, has ·emerged. The original object of this development was the conversion of long-wave; into short-wave light ("wavelength-transformation") which was investigat...

An image ultraviolet, visible light, or near infrared is projected onto the transparent window of the vacuum tube as shown in Fig. 1. The vacuum side of this window carries a sensitive layer called the photocathode. Light radiation causes the emission of electrons from the photocathode into the vacuum which are then accelerated by an applied DC voltage towards a luminescent screen (phosphor scr...

During the intraoperative radiograph generation process with mobile image intensifier systems (C-arm) most of the radiation exposure for patient, surgeon and operation room personal is caused by scattered radiation. The intensity and propagation of scattered radiation depend on different parameters, e.g. the intensity of the primary radiation, and the positioning of the mobile image intensifier...
