We developed the ADMAP ADvanced MAP) system as a local area network for our Distributed Instrumentaion Control System (DCS) with a broadcast communications function. ADMAP is an open system based on the Manufacturing Automation Protocol (MAP), which is advancing as an international standard, but also providing real-time performance, which is weak in MAP.
The new MAP-based LAN can be used not only for electrical and computer control. This paper describes the new MAP-based LAN and discusses distributed control systems using this LAN to integrate instrumentation, electrical, and computer controls. 相似文献

The investigation on the usefulness of water absorbable polymer (Poys® SA-20) for the preparation of sustained release suppository was performed. To prepare the sustained release suppository, sodium diclofenac solution is absorbed into the sphere polymer, and the particles of the polymer after dryness are suspended in the melted triglyceride suppository base, followed by solidification. The sustained release of sodium diclofenac from the suppository was confirmed by the in vitro release study with slow release of sodium diclofenac and by the in vivo absorption study in dogs with an avoidance of transient high plasma diclofenac concentration and a prolong of plasma diclofenac concentration. 相似文献

The molecular structure of kinamycin C has been determined by means of an X-ray study of its p-bromobenzoate derivative, C31H23N2O11Br. The crystals are monoclinic, P21, with four molecules of the derivative and four molecules of benzene in a unit cell of dimensions: a = 18.404 ± 0.005, b = 21.299 ± 0.004, c = 9.049 ± 0.001 Å, and β = 90.07 ± 0.03°. Reflection intensities were measured visually from equi-inclination Weissenberg photographs taken with Cu Ka radiation. The structure was solved by the heavy-atom method, and was refined by the block-diagonal-matrix least-squares method using anisotropic temperature factors for all the atoms. The final R factor is 8.9%. The stereostructures of the two crystallographically independent molecules are almost identical. The skeleton of the molecule is made up of four fused rings: two of these form a 1,4-naphthoquinone system and the rest are a pyrrole and a cyclohexene ring. A cyano group is bonded to the nitrogen atom of the pyrrole ring, which is rather unusual in an antibiotic. 相似文献

The Discrete Weibull Distribution 总被引:3,自引:0,他引:3
The discrete Weibull distribution is defined to correspond with the Weibull distribution in continuous time. A few properties of the discrete Weibull distribution are discussed. 相似文献

The authors apply periodic replacement with minimal repair at failure to cumulative damage models: a unit is replaced at time T , at shock N , or at damage Z and undergoes minimal repair between replacements. The mean cost-rate is obtained, and each optimal T *, N *, and Z * to minimize the cost-rate is discussed. A numerical example is given for an exponential case 相似文献

A highly charged uranium (U) ion beam is produced from the RIKEN superconducting electron cyclotron resonance ion source using 18 and 28 GHz microwaves. The sputtering method is used to produce this U ion beam. The beam intensity is strongly dependent on the rod position and sputtering voltage. We observe that the emittance of U(35+) for 28 GHz microwaves is almost the same as that for 18 GHz microwaves. It seems that the beam intensity of U ions produced using 28 GHz microwaves is higher than that produced using 18 GHz microwaves at the same Radio Frequency (RF) power. 相似文献

We present a general framework of hierarchical methods for point cluster analysis on networks, and then consider individual
clustering procedures and their time complexities defined by typical variants of distances between clusters. The distances
considered here are the closest-pair distance, the farthest-pair distance, the average distance, the median-pair distance
and the radius distance. This paper will offer a menu for users to choose hierarchical clustering algorithms on networks from
a time complexity point of view. 相似文献
