Acquisitioning periodicals online is a new mode for libraries. It has five procedures, namely information retrieving by net, choosing and booking, document delivery, confirming orders, and electric payment. Comparing with traditional acquisition of periodicals, the online acquisition of periodicals has many advantages, such as the tremendous information, the straightness, the high efficiency, a...

Electrical capacitance tomography (ECT) is an effective technique for visualizing the distribution of dielectric materials inside a closed pipe or vessel. The design of an ECT system based on LabVIEW is described in this paper. The system can be divided into three parts: sensor system, data acquisition system, and imaging computer. The data acquisition system designed takes C8051F700 MCU as the...

Electron tomography usually suffers from so-called “missing wedge” artifacts caused by limited tilt angle range. An equally sloped tomography (EST) acquisition scheme (which should be called the linogram sampling scheme) was recently applied to achieve 2.4-angstrom resolution. On the other hand, a compressive sensing inspired reconstruction algorithm, known as adaptive dictionary based statisti...

In order to improve the eeciency with which SCUBA (see elsewhere in this conference) operates on the JCMT , a new and innovative data acquisition system has been developed and will be implemented shortly. The fundamental innovation is in the operation of the telescope secondary mirror, merging the function of chopping for sky-elimination, and 'jiggling' to sub-pixel positions to Nyquist sample ...

The new generation of agile satellites provides wider movement regarding its predecessors. However, this characteristic introduces difficulty in the scheduling of the image capture. The aim of this paper is to find optimal solutions of the image capture process maintaining an acceptable quality of the images. As obtaining the exact solution is a very expensive process speaking in computation ti...

Selecting the appropriate acquisition mode for a required technology, is one of the critical strategic decisions in formulating a technology strategy. Although a number of factorswere found to be influential in the choice of technology acquisitionmode, it still remains a void in the literature how tomake a strategic decision, based on a huge set of those factorswith the help of a systematic app...

OBJECTIVES Use of a positron emission tomography (PET)/single-photon emission computed tomography (SPECT) system facilitates the simultaneous acquisition of images with fluorine-18 fluorodeoxyglucose ((18)F-FDG) and technetium ((99m)Tc)-tetrofosmin. However, (18)F has a short half-life, and 511 keV Compton-scattered photons are detected in the (99m)Tc energy window. Therefore, in this study, we...
