In recent years, Service Oriented Architecture (SOA) technologies are emerging as a powerful vehicle for organizations that need to integrate their applications within and across organizational boundaries. In addition, organizations need to make better decisions more quickly. Moreover, they need to change those decisions immediately to adapt to this increasingly dynamic business environment. It is primarily a question in ensuring the decisional aspect by adopting the SOA as a support architecture. In this paper, we describe a new approach called SOA\(^\mathrm{+d}\) based on a certain number of standards. It is going to be studied on three dimensions: The first is related to the definition of the information system implied in the SOA based on the use case model. The second develops the business dimension which is based on the BPMN (Business Process Modeling Notation). The last dimension addresses the need of decision; we use the new standard decision model and notation (DMN) which is recently approved by Object Management Group (OMG) and considered as a simple notation to specify the decision. Finally, Service Oriented Architecture Modeling Language (SoaML) will be used for design of several services. We also present our meta-model Decisional Model of Service (DMS) to define a new set of concepts necessary for modeling the three levels. Some of them are already known, whereas others are new and are proposed as an element of this work. we illustrate our proposal with a real case study in the Pharmacy Inventory Management. 相似文献

The aim of this paper is to generalize the conic domain defined by Kanas and Wisniowska, and define the class of functions which map the open unit disk E onto this generalized conic domain. A brief comparison between these conic domains is the main motivation of this paper. A correction is made in selecting the range interval of order of conic domain. 相似文献

The effects of silver (Ag) and antimony (Sb) substitution on low-density YBa2Cu3O δ (YBCO) superconductor were investigated. Two series of sample with a nominal composition of YBa2?x Ag x Cu3O δ and YBa2?x Sb x Cu3O δ where x=0.05, 0.10, 0.15, 0.20, 0.30, 0.40 and 0.50 were synthesized and characterized. All Ag-doped samples showed metallic behavior at the normal state and T C?onset was found at 90 K. T C?zero decreased as the Ag concentration increased. Optimum Ag concentration was achieved at x=0.20 where T C?zero has the highest value of 87 K and J C at 70 K is 16.50 A/cm2. For Sb-doped case with x≤0.30, the samples showed metallic behavior above T C?onset while semiconducting behavior was shown for x≥0.40. The optimum Sb concentration was achieved at x=0.15 where T C?zero is 85 K and J C value measured at 70 K is 2.75 A/cm2. T C?onset and T C?zero were found to decrease toward higher Sb concentration. The crystallographic structure transformed to tetragonal in Sb-doped samples of x≥0.30 while other samples remain orthorhombic. 相似文献

The effect of citric acid (CA) addition was studied on the HDS of thiophene over Co–Mo/(B)/Al2O3 catalysts. The catalysts were characterized by means of LRS, Mo K-edge EXAFS, NO adsorption capacity measurements, and UV–vis spectra. The catalysts were subjected to a chemical vapor deposition (CVD) technique using Co(CO)3NO as a precursor of Co in order to get deeper insights into the effect of citric acid addition. It was shown that the HDS activity was enhanced by the citric acid addition up to the CA/Mo mole ratio of around 1 and leveled off with further addition. The amount of Co anchored by the CVD was increased by the addition of citric acid, suggesting an increase in the dispersion of MoS2 particles on the catalyst by the simultaneous presence of Co, Mo and citric acid, in conformity with the increase in the NO adsorption capacity. In contrast to Co–Mo catalysts, the edge dispersion of MoS2 particles in Mo/B/Al2O3 was not affected by the addition of citric acid. The LRS, UV–vis spectra and Mo K-edge EXAFS showed that Co–CA and Mo–CA surface complexes are formed by the addition of citric acid. The Co–CA surface complex is more preferentially formed on CoMo/Al than on CoMo/B/Al, in agreement with a greater promoting effect of citric acid at a lower CA/Mo mole ratio for CoMo/Al than for CoMo/B/Al. 相似文献

Uniform fine particles of nickel basic carbonate were synthesized by heating, aqueous solution containing 0.08 mol dm−3 nickel sulfate and 0.8 mol dm−3 urea, at 85°C for various periods of time. These particles were then coated with copper compound by heating them in aqueous
dispersion, containing urea and copper nitrate, at 85°C. The coating material was found to be amorphous and was composed of
Cu2(OH)2CO3. The coating mixture, when heated under similar conditions in the absence of the dispersed cores, produced greenish dispersion
of the precipitated particles [coating precursor solids]. The later were also amorphous in nature and had the same chemical
composition [Cu2(OH)2CO3] as that of the coating material of the coated particles. Air-dried core, coated, and coating precursor materials were calcined
at 700°C for 1 h at the heating rate of 5°C min−1 in the air atmosphere, which converted them into NiO, NiO[core]/CuO[coating], and CuO, respectively. Scanning electron microscopic examination showed no sintering occurred in all these solids during
the calcinations process and the particles retained their identities to a significant extent. 相似文献

Five different commercial milk clotting preparations (bovine rennet, calf rennet, calf rennet-porcine pepsin mixture, Mucor miebei protease, and modified Mucor miehei protease) were adjusted to equivalent milk clotting activities and then used to clot milk. Percentages of protein in the resulting wheys were compared. Calf rennet, bovine rennet, or modified Mucor miehei protease caused less loss of protein to the whey than Mucor miehei protease or calf rennet-porcine pepsin mixture. The five enzyme preparations were then fractionated by gel filtration. Fractions with milk clotting activity were pooled. Original enzyme preparations and the pooled fractions made from them were standardized to the same clotting activity, then used to coagulated milk to compare their effect on protein loss to the whey. Fractionation significantly improved protein recovery when bovine rennet and calf rennet-porcine pepsin mixture were used as coagulants but not when calf rennet, Mucor miehei protease, or modified Mucor miehei protease were used. 相似文献

Poly(N-isopropylacrylamide-acrylamide-methacrylic acid) [p(NIPa-AAm-Ma)] polymer microgels were prepared by free radical precipitation polymerization method. AgNPs were fabricated in the sieves of polymer network by chemical reduction using AgNO3 salt as a precursor of silver ions. Various techniques like dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared microscopy (FTIR), and UV-Visible spectroscopy were used for characterization of pure and composite microgels. The diameter of AgNPs fabricated in polymeric network was found to be in the range of 10-15 nm. Stimuli responsive behavior of hybrid microgels was same as that of pure microgels. Catalytic efficiency of the hybrid microgels was investigated by reducing 4-Nitroaniline (4-NA) into 4-Aminoaniline (4-AA) using NaBH4 as reducing agent under different conditions of temperature of the medium, concentration of reducing agent, 4-Nitroaniline and hybrid microgels to explore the catalysis process. Kinetic and thermodynamic aspects of reduction of 4-Nitroaniline in the presence of catalyst were also discussed on the basis of values of Arrhenius and Eyring parameters like pre-exponential factor, activation energy, enthalpy of activation and entropy of activation. Catalytic activity of the hybrid microgels was found to be thermally tunable in the temperature range of 25-70 oC. The value of rate constant (k app ) for reduction of 4-NA was minimum at 55 °C, which can be attributed to volume phase transition of the hybrid microgels. 相似文献
