We design a single bunch transverse beam size monitor which will be tested to measure the 28.5 GeV electron/positron beam at the SLAC FFTB beam line. The beam size monitor uses the CCD images of the interference pattern of the optical diffraction radiation from two slit edges which are placed close to the beam path. In this method, destruction of the accelerated electron/positron beam bunches d...

The conditions for baryogenesis in the early universe are well-known (cf. Refs. [1, 2]): 1. C and CP violation, 2. thermal nonequilibrium, 3. violation of baryon number conservation. How realistic are these requirements? Well, noninvariance under the charge conjugation transformation (C) and the combined charge conjugation and parity reflection transformation (CP) have been observed in the labo...

In this paper, we experimentally tested the positioning repeatability of MR-compatible manipulator with a CCD laser micrometer inside MRI. To evaluate the performance of MR-compatible manipulator inside MRI, the measuring system must be confirmed to work correctly inside MRI in advance. Therefore, the measuring system was tested to see if it can measure a specimen similarly regardless to inside...

Coupled map models with variable connection weights between the units are studied. A generally observed feature in this type of model is the appearance of the units with massive outgoing connections. Such structure formation is the consequence of the feedback between unit and connection dynamics.

In this paper, an omnidirectionnal range sensor is reported. This active vision sensor combines a CCD camera and a laser diode. We use two methods to obtain the depth of the scene: a calibration method and a least square method. We describe the prototype we made. Experimental results are presented. A comparative test shows that this sensor seems to be as accurate as a laser telemeter but less s...

The unique SLD CCD vertex detector combined with the highly-polarised electron beam allow us to search for an anomalous chromomagnetic coupling of the b-quark, as well as P-odd, T N-odd and CP-odd processes at the bbg vertex.

It is significant to monitor crop waterlogging range timely and correctly for later field management, agricultural insurance and yield prediction. The change regularity of paddy injured growth was analyzed and the sensitive parameters of growth stress were screened. The model of identifying the paddy waterlogging range based on change vector analysis (CVA) was developed by using the HJ-1/2 CCD ...

This paper describes the fundamentals of the image-resolved luminance and color measurement technique. Its aims and solutions are presented. The determination of image-resolved luminance and color measurements is the state-of-the-art in many applications, e.g. for road or street lighting. In today’s devices, luminance and color measuring cameras are attached to high-quality Charge Coupled Devic...

This paper describes the coupling of FEFLO, a general purpose compressible and incompressible flow solver based on adaptive unstructured grids, with SIMPACT, a general purpose, large deformation, explicit structural dynamics code developed at the Center for Numerical Methods in Engineering (CIMNE). Details on the codes as well as the coupling strategy employed are given. An example illustrates ...
