Noisy chaotic neural network for resource allocation in high-speed train OFDMA system

High-speed train communication system is a typical high-mobility wireless communication network. Resource allocation problem has a great impact on the system performance. However, conventional resource allocation approaches in cellular network cannot be directly applied to this kind of special communication environment. A multidomain resource allocation strategy was proposed in the orthogonal frequency-division multiple access （OFDMA） of high-speed. By analyzing the effect of Doppler shift, sub-channels, antennas, time slots and power were jointly consid- ered to maximize the energy efficiency under the constraint of total transmission power. For the purpose of reducing the computational complexity, noisy chaotic neural network algorithm was used to solve the above optimization problem. Simulation results showed that the proposed resource allocation method had a better performance than the traditional strategy.

Joint channel and power allocation scheme for cognitive wireless networks

Cognitive radio (CR) is a promising technology deemed to improve the efficiency of spectrum utilization. This paper considers a spectrum underlay cognitive radio network, in which the cognitive users (CUs) are allowed to use the radio spectrum concurrently with the primary users (PUs) under the interference temperature constraint. We investigate the system performance by using the proposed joint channel and power allocation scheme under two transmit strategies to achieve higher data rates and performance diversity gain respectively. Simulation results show that the proposed scheme provides a significant improvement on the bit error rate (BER) performance and spectrum efficiency of a cognitive wireless network.

Unequal decoding power allocation for efficient video transmission

We present an unequal decoding power allocation （UDPA） approach for minimization of the receiver power consumption subject to a given quality of service （QoS）, by exploiting data partitioning and turbo decoding. We assign unequal decoding power of forward error correction （FEC） to data partitions with different priority by jointly considering the source coding, channel coding and receiver power consumption. The proposed scheme is applied to H.264 video over additive white Gaussion noise （AWGN） channel, and achieves excellent tradeoff between video delivery quality and power consumption, and yields significant power saving compared with the conventional equal decoding power allocation （EDPA） approach in wireless video transmission.     

Adaptive resource allocation algorithm for internet of things with bandwidth constraint

In order to improve the transmission accuracy and efficiency of sensing and actuating signals in Internet of Things(IoT) and ensure the system stability,an adaptive resource allocation algorithm is proposed,which dynamically assigns the network bandwidth and priority among components according to their signals’ frequency domain characteristics.A remote sensed and controlled unmanned ground vehicle(UGV) path tracking test-bed was developed and multiple UGV’s tracking error signals were measured in the simulation for performance evaluation.Results show that with the same network bandwidth constraints,the proposed algorithm can reduce the accumulated and maximum errors of UGV path tracking by over 60% compared with the conventional static algorithm.     

京津冀高等教育协同创新行与思

依据《京津冀协同发展规划纲要》等标识性政策文件,将京津冀都市圈建设划分出早期阶段和新型阶段,就逻辑构思、功能分区等方面进行政策分析。近几年天津市在前沿领域创建国家研究中心和创新平台,其扩展的数量规模在2-3年内超过以往10年发展的总和,然而其成绩和存在的问题同样是显著的。继而,在经济社会发展和高等教育协同创新两个方面与长三角等区域进行比较研究,反映出长三角区域和珠三角区域在自主创新的活跃度方面均略高于京津冀区域,由此提供了一定程度上发挥市场资源配置功能的范例。相关顶层决策上进行常态化设置,按年度召开京津冀首脑联席会议,就建设区域协同长效机制而言是一个行之有效的实现路径。     

小叶榕榕-蜂互利共生系统中资源分配模式

为了研究榕-蜂互利共生系统中繁殖资源的分配模式,本研究比较了小叶榕榕果内的种子及小蜂后代数量。研究结果表明：榕果内传粉榕小蜂小蜂数量显著高于种子数量。随着榕果内小蜂后代数量的增加,种子数量也呈增加的趋势,但其增加趋势并不显著。这说明传粉榕小蜂更倾向于在榕果内孕育更多的后代,而非种子。所以说在榕-蜂互利共生系统资源的分配上,传粉榕小蜂应该占主导地位。除传粉榕小蜂外,小叶榕榕果内还寄生着一种非传粉榕小蜂W.kurandensis,该种小蜂仅影响种子产出,而不影响传粉榕小蜂的后代数。这可能是由于该种小蜂与种子都利用榕果内同种空间分布类型繁殖资源资源造成的。

PID-based bit allocation strategy for asymmetric stereoscopic video coding with fuzzy quality controller

Asymmetric stereoscopic video coding can take advantage of binocular suppression in human vision by representing one of the two views in lower quality.This paper proposes a bit allocation strategy for asymmetric stereoscopic video coding.In order to improve the accuracy of bit allocation and rate control in the left view,a proportionalintegral-derivative controller is adopted.Meanwhile,to control the quality fluctuation between consecutive frames of the left view,a quality controller is adopted.Besides,a fuzzy controller is proposed to control the variation in quality between the left and right views by comparing the PSNR disparity of two views with a fixed threshold,which is used to quantize the binocular psycho-visual redundancy and adjust the quantization parameter (QP) of the right view correspondingly.The proposed algorithm has been implemented in H.264/AVC video codec,and the experimental results show its effectiveness in rate control while keeping a good quality for the left view,and fewer bits are allocated for the right view so that the overall bit rate is saved by 7.2% at most without the loss of subjective visual quality for stereoscopic video.

凹资源配置问题的混合动态规划方法

Concave resource allocation problem is an integer programming problem of minimizing a nonincreasing concave function subject to a convex nondecreasing constraint and bounded integer variables. This class of problems are encountered in optimization models involving economies of scale. In this paper, a new hybrid dynamic programming method was proposed for solving concave resource allocation problems. A convex underestimating function was used to approximate the objective function and the resulting convex subproblem was solved with dynamic programming technique after transforming it into a 0-1 linear knapsack problem. To ensure the convergence, monotonicity and domain cut technique was employed to remove certain integer boxes and partition the revised domain into a union of integer boxes. Computational results were given to show the efficiency of the algorithm.
