In this paper, we focus our attention on the issue of MAGDM under interval type-2 fuzzy environment where all the information provided by the decision makers is characterized by IT2FSs and the information about the attribute weights are partly known and completely unknown. Firstly, some basic concepts are introduced. Then, a new definition of the cross entropy which consider three aspects of fuzziness, hesitancy and interval information is given. Interval type-2 fuzzy entropy is proposed on the basis of the cross entropy. Furthermore, two ranking-entropy optimal models of each alternative are built. A new approach to multiple attribute group decision making with IT2FSs based on interval type-2 fuzzy cross-entropy and ranking value is shown. Finally, we give a practical example to verify the feasibility of our method and make some comparisons with other previous methods. The results verify the validity and effectiveness of our proposed method.

This paper studies the problem of how to choose the viewpoint for taking good photographs for architecture. We achieve this by learning from professional photographs of world famous landmarks that are available in the Internet. Unlike the previous efforts devoted to photo quality assessment which mainly rely on visual features, we show in this paper combining visual features with geometric features computed on the 3D models can result in a more reliable evaluation of viewpoint quality. Specifically, we collect a set of photographs for each of 6 world famous architectures as well as their 3D models from Internet. Viewpoint recovery for images is carried out by an image-model registration process, after which a newly proposed viewpoint clustering strategy is exploited to validate users' viewpoint preference when photographing landmarks. Finally, we extract a number of 2D and 3D features for each image based on multiple visual and geometric cues, and perform viewpoint recommendation by learning from both 2D and 3D features, achieving superior performance over using solely 2D or 3D features. We show the effectiveness of the proposed approach through extensive experiments. © 2016 The Author(s) Eurographics Proceedings © 2016 The Eurographics Association.

BigNeuron is an open community bench-testing platform with the goal of setting open standards for accurate and fast automatic neuron tracing. We gathered a diverse set of image volumes across several species that is representative of the data obtained in many neuroscience laboratories interested in neuron tracing. Here, we report generated gold standard manual annotations for a subset of the available imaging datasets and quantified tracing quality for 35 automatic tracing algorithms. The goal of generating such a hand-curated diverse dataset is to advance the development of tracing algorithms and enable generalizable benchmarking. Together with image quality features, we pooled the data in an interactive web application that enables users and developers to perform principal component analysis, t-distributed stochastic neighbor embedding, correlation and clustering, visualization of imaging and tracing data, and benchmarking of automatic tracing algorithms in user-defined data subsets. The image quality metrics explain most of the variance in the data, followed by neuromorphological features related to neuron size. We observed that diverse algorithms can provide complementary information to obtain accurate results and developed a method to iteratively combine methods and generate consensus reconstructions. The consensus trees obtained provide estimates of the neuron structure ground truth that typically outperform single algorithms in noisy datasets. However, specific algorithms may outperform the consensus tree strategy in specific imaging conditions. Finally, to aid users in predicting the most accurate automatic tracing results without manual annotations for comparison, we used support vector machine regression to predict reconstruction quality given an image volume and a set of automatic tracings.

A broadband dual-polarized magneto-electric dipole antenna excited by Γ-shaped strips is presented in this communication. The proposed antenna contains three parts. The radiating element of the proposed antenna is a combination of the vertically oriented shorted patch, the planar dipole and the bottom plate. The two orthogonal Γ-shaped feeding strips connected with 50 Ω SMA launchers are used to excite the proposed antenna. The corner reflector can effectively improve the radiation performance of the proposed antenna. As shown in simulated results, the impedance bandwidth of the proposed antenna is 48% for standing-wave ratio (SWR) ≤2 (0.86-2.47 GHz), the available bandwidth of the antenna covers the 2G/3G/LTE bands, and the antenna obtains a stable gain that the average value is 10 dBi. Meanwhile, the antenna has good performance in radiation characteristics. The proposed antenna can be applied to the base station communication systems.

Journal of Communications 2016年第10期11卷 896-902页

Spectral efficiency and transmission reliability are among the main design considerations of modern wireless communication systems. In order to solve the problems of high decoding complexity, low spectrum utilization in bidirectional multi-relay cooperative communication system, combining the advantages of Random Cyclic Delay Diversity (RCDD) technology and Adaptive Forwarding Factor (AFF), a distributed space-time-frequency cooperative transmission scheme is proposed in this paper, which has the advantages of low decoding complexity and high spectrum utilization. Compared with the scheme only using Cyclic Delay Diversity (CDD) technology, this scheme can further excavate the diversity gain of the system and improve the performance of Bit Error Ratio (BER) and channel capacity. © 2016 Journal of Communications.

Progress In Electromagnetics Research C 2016年 62卷 149-156页

A compact multiband omnidirectional antenna for the reception of GNSS signals on artillery projectiles is designed in this paper. The proposed antenna consists of a metallic cone comprising a T-shaped monopole. It exhibits a broad bandwidth from 1.22 GHz to 1.28 GHz and from 1.44 GHz to 1.75 GHz, covering GPS L1, Galileo E2-L1-E1, GLONASS G1 and G2, CNSS B1 and B3. Measured results show that an omnidirectional radiation pattern is achieved, and the non-circularity in the azimuthal plane (xy-plane) is less than 2 dB for all the desired bands. Then the measured 6 dB beamwidth is about 110◦ in the presence of a finite 20 millimeters (mm) radius ground plane. Such an antenna has the potential to be easily used for small artillery projectiles. © 2016, Electromagnetics Academy. All rights reserved.

A wideband omnidirectional horizontally polarized (HP) antenna is proposed and investigated in this paper. The antenna is composed of four arc printed dipoles, a small circular patch, four tapered microstrip transmission lines and four pairs of parasitic strips. To verify the performance of the antenna, simulations and measurements are carried out and discussed. The measured results show that the proposed antenna exhibits a 10-dB impedance bandwidth of 59.3% (2.23- 4.11 GHz). With an omnidirectional radiation pattern in E-plane, the proposed antenna has a peak gain of around 2 dBi across the operational band. The low profile and compact design, along with omnidirectional radiation pattern, make it ideal for wireless applications operated within WLAN (2.4- 2.484 GHz) and WiMAX (2.3GHz, 2.5GHz and 3.5GHz) frequency bands.

作者： Guangyang Xu Yufa Sun Ming Yang Weiwei Liu Dong Zhou Key Lab of Intelligent Computing & Signal Processing Anhui University Hefei China

In this article, an omnidirectional circularly polarized (CP) patch antenna with bandwidth broadening is proposed. The antenna is composed of a circular patch with four L-shaped slots, a ground plane loaded a metal sleeve and a set of conductive vias. In order to broaden the impedance bandwidth, four parasitic strips are also sequentially rotated around the patch. As a result, it exhibits an omnidirectional CP radiation in the azimuthal plane. To verify the design, a prototype operating at 2.4 GHz industrial, scientific and medical band (ISM band) has been fabricated and measured. Measurement results show that the proposed antenna can achieve a -10 dB impedance bandwidth of 8.2% (ranges from 2.33 to 2.53 GHz) and a 3 dB axial ratio (AR) bandwidth of 9.2% (ranges from 2.29 to 2.51 GHz) in the azimuthal plane. The results indicate that the proposed antenna is a good candidate for 2.4 GHz ISM band applications.
