Abstract An accurate prediction of tray hydraulics is very important for large diameter trays design, and vapor cross-flow channeling (VCFC) is one of the key points that affect the hydraulics calculation. Therefore, in this article, a theoretical analysis was first conducted to reveal that the energy of gas–liquid on the tray was closely related to its flow state. Then, a model was obtained on the basis of the principle of the lowest energy, which can be used to calculate VCFC. The model shows that the ratio of dry tray pressure drop to liquid height on a tray determines the gas distribution on the tray. Finally, the model was tested by comparisons with experimental results available in reference. The agreements are good. Furthermore, the effects of liquid load and fractional hole area on VCFC were studied. The results are consistent with the field experience summarized in literatures. © 2014 American Institute of Chemical Engineers AIChE J, 61: 1032–1042, 2015

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. In a first configuration, a UE monitors MSI based on a first MSP. The UE receives an MBMS service. The MBMS service is a group communication associated with low latency. Information associated with the MBMS service is included in the MSI.

Disclosed is a ceramic shell filter device. A ceramic shell (1) forms a cavity. The cavity comprises: a flow division part (1-2) which is located at the upper part of the shell, and an upper end thereof is a filter device inlet; a flow converging part (1-7) which is located at the lower part of the shell, and a lower end thereof is a filter device outlet; and C-type running channels which are located in the middle, wherein the C-type running channels are connected in parallel, the C-type running channels are in communication between the flow division part and the flow converging part respectively, and a filter (2) is arranged in each of the C-type running channels. By means of the design of flow division, filtration and flow convergence, the ceramic shell filter device achieves the overall filtration of molten metal at a high flow rate outside a casting mould, thereby satisfying the requirement of the overall filtration of molten metal for large steel casting and ultra-large iron casting outside a casting mould.

In this paper, the behavior of CuO in CuO-doped SnO 2 nanoparticles was investigated; the effect of the addition of CuO on physical properties and arc erosion behavior of Ag/SnO 2 materials were examined. The CuO-doped SnO 2 nanoparticles were structurally characterized by X-ray diffraction (XRD) and High-resolution Transmission Electron Microscope (HR-TEM). The surface morphology of arc eroded Ag/SnO 2 materials was characterized by Scanning Electron Microscope (SEM). The results indicated that the crystallized monoclinic CuO in CuO-doped SnO 2 nanoparticles has formed and distributed on the surface of SnO 2 nanoparticles. It was found that Ag/SnO 2 materials adding CuO exhibited denser microstructure and better hardness as well as better arc erosion resistance compared with Ag/SnO 2 materials. The arc erosion results and theoretical analysis indicated that the addition of CuO in Ag/SnO 2 materials can obviously inhibited the spattering loss of molten droplets.

More than 400 young Northeastern China women were measured, and the body data were collected by mix-measurement of 3D scanner and manual method, and the main sizes were extracted to descript the total anthropometric characterizes. The high mean value of the Northeastern young women is 162.3 CM, which is 5.75 CM higher than the national adult females. In the high direction, the other mean values of the samples are variously higher than the national adult females. Overall, the young Northeastern China women are taller than the national adult females and well proportioned. In the width direction, the mean values of bust, waist and neck of the 18-25 years old young women are larger than the national adult females, except the hip.

In this paper, a robust algorithm is proposed for reconstructing 2D curve from unorganized point data with a high level of noise and outliers. By constructing the quadtree of the input point data, we extract the "grid-like" boundaries of the quadtree, and smooth the boundaries using a modified Laplacian method. The skeleton of the smoothed boundaries is computed and thereby the initial curve is generated by circular neighboring projection. Subsequently, a normal-based processing method is applied to the initial curve to smooth jagged features at low curvatures areas, and recover sharp features at high curvature areas. As a result, the curve is reconstructed accurately with small details and sharp features well preserved. A variety of experimental results demonstrate the effectiveness and robustness of our method.
