In this paper, we proposed a video super-resolution (SR) system. Image or video super-resolution has been studied for a long time. Recently, convolutional neural network (CNN) has been applied for image SR and provided impressive synthesized high-resolution results. Although CNN can provide better synthesized quality than traditional SR methods by preserving more high frequency information, the computational complexity is main concern for video super-resolution. In order to accelerate processing time, we integrated motion information into the SR system and then the SRCNN is used to reconstruct high resolution image. In other words, rather than reconstructing the whole frames for the input video, changed regions between two consecutive frames are explored and processed. Only unmatched patches were reconstructed via SRCNN in the proposed system. In addition, two additional strategies are proposed to speed up the processing time and reduce unexpected synthesized effects. According experimental results, the proposed system can save 37% computation time in one test video with dynamic changes.
本文提出了一种视频超分辨率(SR)系统。图像或视频的超分辨率已经研究了很长时间。最近,卷积神经网络(CNN)被应用于图像SR,并提供了令人印象深刻的合成高分辨率结果。虽然CNN可以通过保留更多的高频信息来提供比传统SR方法更好的合成质量,但计算复杂度是视频超分辨率的主要问题。为了加快处理速度,我们将运动信息整合到SR系统中,然后利用SRCNN重建高分辨率图像。换句话说,不是重建输入视频的整个帧,而是探索和处理两个连续帧之间的变化区域。在该系统中,通过SRCNN只重建了不匹配的斑块。此外,还提出了两种策略来加快处理时间和减少意外的综合效应。实验结果表明,在一个动态变化的测试视频中,该系统可以节省37%的计算时间。

Number theoretic transform with the modular arithmetic operations can perform convolution efficiently in a ring without round-off errors. In this paper, a new efficient architecture of the transform have been proposed which support a various operand size. To have a balanced trade-off between area and latency, a variant constant geometry architecture is used which the forward and backward sub-stage used the same computation pattern. In addition, a XOR-based multi-ported RAM is adopted to accelerate the memory access which allow multiple simultaneous reads and writes efficiently. As a result, the developed accelerator can achieve lower area-latency FPGA compared to other designs.
采用模算术运算的数论变换可以有效地完成环内的卷积,且没有舍入误差。本文提出了一种支持不同操作数大小的高效转换结构。为了在面积和延迟之间取得平衡,使用了一种可变的常量几何结构,其中向前和向后子阶段使用相同的计算模式。此外,采用了基于xor的多端口RAM来加速内存访问,从而有效地实现了多个同时读写。因此,与其他设计相比,所开发的加速器可以实现更低的区域延迟FPGA。

A cluster validity index (CVI) classification method is applied to enhance the performance of existing Multiple-Attribute Decision Making (MADM) method. This paper proposed index-based method is called the FRM-index method which combined Fuzzy Set (FS), Rough Set (RS), and a cluster validity index function. The effectiveness of the proposed FRM-index method is evaluated by comparing the classification results obtained for the relating UCI datasets using a statistical approach. Overall, the results show that the proposed method not only provides a more reliable basis for the extraction of decisionmaking rules for multi-output datasets, but also fills out the uncertainty and facilitates an effective MADM built.

In recent decades, with the rapid development and popularization of Internet and computer technology, cloud computing had become a highly-demanded service due to the advantages of high computing power, cheap cost of services, scalability, accessibility as well as availability. However, a fly in the ointment was that the system is more complex while dispatching variety of tasks to servers. It means that dispatching tasks to the servers is a challenge since there has a large number of heterogeneous servers, core and diverse application services need to cooperate with each other in the cloud computing network. To deal with the huge number of tasks, an appropriate and effective scheduling algorithm is to allocate these tasks to appropriate servers within the minimum completion time, and to achieve the load balancing of workload. Based on the reasons above, a novel dispatching algorithm, called Advanced MaxSufferage algorithm (AMS), is proposed in this paper to improve the dispatching efficiency in the cloud computing network. The main concept of the AMS is to allocate the tasks to server nodes by comparing the SV value, MSV value, and average value of expected completion time of the server nodes between each task. Basically, the AMS algorithm can obtain better task completion time than previous works and can achieve loadbalancing in cloud computing network.
近几十年来,随着互联网和计算机技术的快速发展和普及,云计算以其计算能力强、服务成本低、可扩展性强、可访问性强、可用性好等优势,成为一项备受需求的服务。然而,美中不足的是,在向服务器分派各种任务时,系统更加复杂。这意味着在云计算网络中,由于存在大量异构服务器,核心和各种应用服务需要相互协作,因此向服务器调度任务是一个挑战。为了处理大量的任务,一种合适有效的调度算法是在最短的完成时间内将这些任务分配到合适的服务器上,并实现工作负载的负载均衡。基于以上原因,本文提出了一种新的调度算法——高级最大容忍算法(AMS),以提高云计算网络中的调度效率。AMS的主要概念是通过比较每个任务之间服务器节点的SV值、MSV值和期望完成时间的平均值,将任务分配给服务器节点。基本上,AMS算法可以获得比以往工作更好的任务完成时间,并且可以在云计算网络中实现负载均衡。

A modified SLM scheme with two-stage scrambling for PAPR reduction in OFDM systems 一种改进的两阶段置乱SLM方案用于OFDM系统中PAPR的降低

This paper proposes a modified selective mapping (SLM) technique to improve the high computational complexity required for the SLM technique in the orthogonal frequency division multiplexing (OFDM) system, and it can be regarded as a suboptimal SLM technique for peak to average power ratio (PAPR) reduction. The proposed method which generates W candidate signals is through the phase factor to carry out the first phase scrambling for the input signal to produce W/2 signals, followed by the inverse fast Fourier transform (IFFT) and then the second phase scrambling to produce the remaining W/2 signals. The generation mechanism of the phase factor is mainly based on the sub-code of the Reed-Muller codes with random ordering. The simulation results show that adopting the proposed method results in the improved performance of PAPR that are suboptimal compared to adopting the SLM technique but it simplifies the number of adders and multipliers required by the traditional SLM technique.
针对正交频分复用(OFDM)系统中SLM技术计算复杂度高的问题,提出了一种改进的选择性映射(SLM)技术,并将其视为降低峰值平均功率比(PAPR)的次优SLM技术。本文提出的产生W个候选信号的方法是通过相位因子对输入信号进行第一相置乱产生W/2信号,然后进行快速傅里叶反变换(IFFT),然后进行第二相置乱产生剩余的W/2信号。相位因子的产生机制主要是基于随机排序的里德-穆勒码的子码。仿真结果表明,采用该方法可以提高PAPR的性能,但与采用SLM技术相比,性能不是最优的,但它简化了传统SLM技术所需的加法器和乘法器的数量。

As the development and population of Electronic Commerce (EC) keeps growing, the sheer volume of data makes the EC more challenge to handle. For example, if the number of products keeps increasing, a regular user-item transaction records may get bigger and bigger which will usually form the sparse matrix. When the data sparsity is formed, the performance of data analysis should be aware. In order to promote the product under hundreds or thousands of items, recommender systems have been intensively studied and are highly applied in the EC environment. One of the most popular recommendation methods is the collaborative filtering (CF) method in which a group of user/customer with similar preference is chosen for the reference of recommendation. It is interesting to notice that the past researches usually didn't consider the sparsity problem when applying the CF recommendation. As a result, the time performance of CF recommendation is, therefore, constrained. To overcome this problem, this research proposes a Simplified Similarity Measure (SSM) for CF recommendation when dealing with the sparsity problem. The proposed SSM method uses the real data from Epinion.com for experiment and for comparison. The results show that SSM method is outperformed the traditional CF methods in terms of time efficiency and recommendation precision.
随着电子商务的发展和人口的不断增长,庞大的数据量给电子商务的处理带来了更多的挑战。例如,如果产品数量不断增加,则常规的用户-物品交易记录可能会越来越大,这通常会形成稀疏矩阵。当数据稀疏性形成后,就应该意识到数据分析的性能。为了在数百或数千个项目下推广产品,推荐系统得到了深入的研究,并在电子商务环境中得到了广泛的应用。其中最流行的推荐方法之一是协同过滤(CF)方法,该方法选择一组具有相似偏好的用户/客户作为推荐的参考。值得注意的是,以往的研究在应用CF推荐时通常没有考虑稀疏性问题。因此,CF推荐的时间性能受到约束。为了克服这一问题,本研究在处理稀疏性问题时,提出了一种简化相似度度量(SSM)用于CF推荐。所提出的SSM方法利用Epinion.com的真实数据进行实验和比较。结果表明,SSM方法在时间效率和推荐精度方面都优于传统的CF方法。

The implementation of multi-path delivery for data flows using Raspberry Pi boards in software-defined networks 在软件定义网络中使用树莓派板实现数据流的多路径传输

In the Internet, Software-Defined Network (SDN) is an attractive issue because it allows network managers to use software program to control and manage the networks instead of the setup of hardware equipment. Therefore, in this study, we established an experiment platform by Raspberry Pi boards and proposed a method, Weight-Based Flow Dividing (WFD) method, to implement the OpenFlow switching in the SDN. The proposed method uses the multipath to transmit the packets by weighted configurations because the single-path transmission causes the routing security at high risk and is difficult to effectively use the path bandwidth. In addition, we use network simulation software Mininet on this study for comparison purposes. The simulations show the results can achieve the multipath transmissions through the hardware OpenFlow switch platform with WFD in different weighted configurations, as Mininet.
在Internet中,软件定义网络(SDN)是一个有吸引力的问题,因为它允许网络管理人员使用软件程序来控制和管理网络,而不是设置硬件设备。因此,在本研究中,我们利用树莓派板搭建了一个实验平台,并提出了一种基于权重的流量划分(Weight-Based Flow divide, WFD)方法来实现SDN中的OpenFlow交换。由于单路径传输存在路由安全风险,且难以有效利用路径带宽,因此采用多路径加权配置传输报文。此外,为了进行比较,我们使用了网络仿真软件Mininet。仿真结果表明,采用不同加权配置的WFD(如Mininet),通过硬件OpenFlow交换平台可以实现多径传输。

The simulations show the results can achieve the multipath transmissions through the hardware OpenFlow switch platform with WFD in different weighted configurations, as Mininet.","PeriodicalId":378618,"journal":{"name":"2017 IEEE 8th International Conference on Awareness Science and Technology (iCAST)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123583014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the relationship between the experience satisfaction and sports attitude for the adolescent with the somatosensory experience of information technology products. Subject to the adolescents ranging from 13 to 15-year olds, this study issues a total of 445 surveys by using cluster sampling. As a result, 415 valid samples are received and the effective response rate is 93.2%. For the collected data, it is at first analyzed for the reliability and the validity, and then descriptive statistics and multiple regression analysis are applied. The main results induced from this study are as below. (1) The experience of Wii Sports can benefit the “Sensory Emotion” of the somatosensory experience. (2) The “Relaxation” of the experience satisfaction is the most impressive; the “Affection” of the exercise attitude is the highest. (3) The “Thinking Action”, “Sensory Emotion” and “Relevance” of somatosensory experiences in Wii Sports can effectively predict the experience satisfaction and sports attitude. (4) The sports attitudes can be effectively predicted by the “Relaxation”, “Physiological” and “Psychological” of the somatosensory experience in Wii Sports. Based on the above results, this study provides some practical suggestions for educational and related units as a reference to achieve an improvement in sports education.
本研究旨在探讨青少年体验满意度与运动态度与资讯科技产品体感体验的关系。本研究以13 ~ 15岁的青少年为研究对象,采用整群抽样的方法共发放问卷445份。共收到有效样本415份,有效回复率为93.2%。对收集到的数据首先进行信度和效度分析,然后运用描述性统计和多元回归分析。本研究得出的主要结果如下:(1) Wii Sports的体验有利于体感体验的“感官情感”。(2)体验满意度的“放松”最令人印象深刻;运动态度的“情感”程度最高。(3)《Wii Sports》体感体验的“思维行动”、“感觉情感”和“关联”能有效预测体验满意度和运动态度。(4)《Wii sports》体感体验的“放松”、“生理”、“心理”三个维度能够有效预测运动态度。基于上述研究结果,本研究为教育及相关单位提供了一些切实可行的建议,以供参考,以实现体育教育的改进。
