A semielliptical trench flush-mounted under a metal plane and filled with double-negative (DNG) metamaterial is considered. The primary field is an electric line source parallel to the trench and located inside the trench or in the half-space above it. The two-dimensional boundary-value problem is solved exactly in terms of infinite series of elliptic-cylinder wavefunctions. In particular, the far...
Based on the demand of material, this paper first selected the evaluating factors about choosing suppliers, and analyzed the correlation among evaluating factors. Then, by combining the merits of Analytic Network Process (ANP) and entropy right, this paper proposed a method to calculate the compound rights of factors. The new method fully takes advantage of the relationship between factors and the...
There are close relationships between traffic volume and transportation volume. The resources and basic data in the traffic volume observation station can be effectively used in calculating the transportation volume of the highway network with that of the highway section. This can help to increase the timeliness of the statistical work of the highway transportation volume and effectively avoid a lot...
Recent computational methods of wafer defect detection often rely on the difference image between an inspected image and its reference image, and highly depend on registration accuracy. In this paper, we present a novel method for defect detection in patterned wafers, based on of the inspected image from the reference image using anisotropic kernels. This method avoids registration between the inspected...
Based on the coordinate transformation theory, arbitrary prism invisibility cloaks which is composed of complex, anisotropic and inhomogeneous materials are designed, the permittivity and permeability tensors of the materials are deduced for arbitrary prism cloaks. Such cloaks should be effective at all frequencies. Numerical simulation results are given to validate the arbitrary prism invisibility...
Regional industrial system is a complex system, it has the characteristics of complex system, among which "emergency " is the most important, while whether the emergency emergerges or not depends on the self-organization degree of the system elements, therefore, in the paper, we first analyzed the structure of regional industrial complex system, knew about the composition of regional industrial...
Equipment support capability is a permanent problem at equipment support realm. Grading the equipment support capability enables better equipment support scheme. This paper applies the theories and methods of fuzzy mathematics and comprehensive evaluation. Based on fuzzy inference, its perform evaluations that are both qualitative and quantitative and contain exact and inexact factors. The paper determines...
A new metric for anomaly detection in hyperspectral imagery is developed to account for anisotropic heavy tails in covariance-whitened data. The anisotropy, consisting of a variation in tail heaviness with principal component number, commonly occurs when the number of linearly independent components representing the data to within the noise level is less than the number of data dimensions. The detection...
Live-Cell Assays are used to study the dynamic functional cellular processes in high-content screening of drug discovery processes. One class of tasks in this application is the tracking of cells and the description of the events and the changes in the cell characteristics. The large amount of data requires fast processing algorithms and compact object and event descriptions. We propose in this paper...
Material shape of car dumper during dumping is analyzed. The weight and rotary inertia of material are changed with the tipping angle during dumping. Material moment and rotary inertia on-line calculation thought is put forward. Object position measuring technology is applied to determine initial parameters and the graph display of whole dumping process is realized by coordinate conversion. The variety...
The focus of this contribution is to define speech acts as institutional actions where modeled institutions are social or informal institutions. With social or informal institution, we mean an institution which is grounded on the acceptances of its members. In the first part of the paper we present a logic of acceptance, goal and action. Then, we specify how agents can create and maintain normative...
In this presentation, a facile method has been developed to produce large quantities of ZnO nanocrystals with hexagonal shape. In the presence of sodium bis (2-ethylexyl) sulfosuccinate (AOT) emulsions as a structure-direct agent, the reaction of hexamethylenetetramine (HMT) in Zn2+ aqueous solution forms ZnO phosphors. Second, both micro-sized and nano-sized platelet-like ZnO nanocrystals have been...
Life cycle inventory (LCI) can be used to quantify the energy input and materials assumption as well as associated with environmental emission of a product system in their whole life cycle, and provide important information to improve the environmental performance, to compare possible alternatives or to establish recommendations for action, product procurement, purchase and disposal. Data flow balanced...
In order to obtain a more efficient method of manganese( II) removal, jar test was used to study the effect of potassium manganese(K2MnO4) pre-oxidation on aluminum chloride (AlCl3) coagulation to remove manganese(II). It was investigated that the effect of the dosage ofK2MnO4, dosing time, sedimentation time and common ions on manganese(II) removal. The results showed that, when K2MnO4 was added...
In order to purify blogical Chinese herbal medicine from wood etractives and hmicellulose at the molecular level, the fresh Chinese-fir cells were extracted in LiOH solution, and were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir cells. The results are as follows: (1) The extraction mass arrived at the maximum value when LiOH concentration is about 17.5%...
In this paper, the ethanol extraction of flavonoids from Jerusalem artichoke was studied. On the basis of single factor tests, the orthogonal test was used in the optimization of technological parameters. The significance of these factors affecting was in the following order: material ratio > concentration of alcohol > extraction temperature > extraction time. Their optimal parameters were:...
In order to overcome the above-mentioned negative effects, the fresh Chinese-fir shavings were extracted in KOH soultion, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17.5%. The micro/nano particles in Chinese-fir shavings would be...
Few studies were mentioned to illustrate the role of plant hormones-IAA and ethylene in split-pit formation. Here, a random sample of 100 developing fruits from 7-year-old early maturing nectarines (Prunus persica L. Batsch cv. Ruiguang 5) was used as test material. The shape index and growth index of the sampled nectarines was comparatively analyzed to show the relation between fruit un-uniform growth...
The behavior of formaldehyde release from plywood was similar to the creep behavior of material and the liquid. So the behavior of the formaldehyde emission from plywood was modeled by the rheological theory. And the Maxwell model, Delvin model and Burger model were used to fit the creep behavior which the formaldehyde released from plywood. The results show that the derived creeping model is fit...
The far-field radiation of a Hertzian dipole for a two-layered gyromagnetic medium has been investigated using the dyadic Green's function. For this purpose, the symmetric property of DGFs has been employed to calculate the dyadic Green's function when an impulse source is placed above the gyromagnetic slab. After obtaining the far-field approximated DGFs, radiation fields are found for a dipole antenna...
