Implementation of a high-speed pipelined FFT processor using dadda multipliers to process two independent data streams 使用数据乘法器处理两个独立数据流的高速流水线FFT处理器的实现
K. Ganesh, P. Pushpalatha
Present real time applications require high speed fast Fourier transform (FFT) processors to process multiple independent data streams. This paper presents a high speed pipelined FFT processor to process two independent data streams concurrently. This processor takes inputs in normal order and generates outputs also in normal order. In this architecture, two N/2-point multipath delay commutator (MDC) FFT architectures are used to process even and odd samples of two data streams separately. To process bit reversal operations at different stages, the processor uses shift registers whose actual purpose is to delay the samples of data streams. So it does not require additional bit reversal circuits for getting normal output order. To get high computational speed, Dadda multipliers are used in the computation of butterfly processing elements. That multiplier is based on row reduction by compressing columns using less full adders and half adders compared to the conventional multipliers. Thus the Dadda multiplier's speed is more and takes less hardware. Therefore, by using the Dadda multipliers, the proposed FFT architecture has high speed of the computation and requires less hardware.
当前的实时应用需要高速快速的傅里叶变换(FFT)处理器来处理多个独立的数据流。本文提出了一种高速流水线式FFT处理器,可以同时处理两个独立的数据流。该处理器以正常顺序接受输入,并以正常顺序生成输出。在该体系结构中,采用两个N/2点多路径延迟换向器(MDC) FFT结构分别处理两个数据流的偶数和奇数样本。为了在不同阶段处理位反转操作,处理器使用移位寄存器,其实际目的是延迟数据流的采样。因此,它不需要额外的位反转电路来获得正常的输出顺序。为了获得较高的计算速度,在蝴蝶加工单元的计算中采用了dadada乘法器。与传统乘法器相比,该乘法器基于行缩减,使用更少的全加法器和半加法器压缩列。因此,Dadda乘法器的速度更快,所需的硬件更少。因此,通过使用Dadda乘法器,所提出的FFT体系结构具有较高的计算速度和较少的硬件需求。

Energy efficiency in “Green construction”: Experience, issues, trends “绿色建筑”中的能源效率:经验、问题、趋势
V. Makarov, O. Novikova, A. Tabakova
One cannot say that “Green construction” is wide-spread in Russia, while in the developed countries it is implemented in both: new construction and reconstruction projects. Therefore, it is important to identify current issues, concerning implementation of “Green construction” in Russia. The objective of this article is to explore the implementation perspectives of “Green” technologies in Russian construction and reconstruction as a common practice. To conduct the research, the following methodologies were used: comprehensive and systematic analysis, synthesis, analogy, logical sampling. The analysis of the Russian local legal requirements is performed and the reasons for the lack of implementation are identified. Moreover, the study of the “Green buildings” construction experience and best practices in the world and in Russia specifically was done. The justification of choice for the more expensive reconstruction or new construction projects is done. The concept of the “Green campus” is proposed, that is a demo-zone for the research and development of “Green building” technologies. The research proposed the new ways of financial funding, reduction of operational costs and testing of new “Green” technologies.

Identification & enhancement of different skin lesion images by segmentation techniques 基于分割技术的不同皮肤病变图像识别与增强
Neetu Mittal, Sudhir Tanwar, S. Khatri
A skin lesion is a portion of skin with an abnormal growth or presence due to a skin disease. Skin diseases at their early stages can be cured very easily; otherwise they begin to spread to other parts of the body and may be deadly. An early detection of skin disease is essential for such patients. Due to the high cost involved in various dermatology testing procedures for every patient, an automated system is required to give better lesion images and vision to help the doctors to further diagnose and prescribe the correct prescription and medication. In this paper, an innovative approach for automatic identification of skin lesions is proposed. To improve the quality of skin lesion images, Median filtering and Sobel edge detection techniques have been implemented for filtering and segmentation. The efficacy of the proposed work has been verified by measuring the entropy of the resultant images obtained for different skin diseases. The performance is tested on a dataset of 70 samples from 150 medical images of different body parts with 10 different classes of skin diseases.
皮肤病变是皮肤的一部分,由于皮肤疾病而出现异常生长或存在。早期的皮肤病很容易治愈;否则,它们开始扩散到身体的其他部位,可能是致命的。对这类患者来说,早期发现皮肤病至关重要。由于每位患者的各种皮肤科检查程序成本高昂,因此需要一个自动化系统来提供更好的病变图像和视力,以帮助医生进一步诊断并开出正确的处方和药物。本文提出了一种新颖的皮肤损伤自动识别方法。为了提高皮肤病变图像的质量,采用中值滤波和Sobel边缘检测技术对图像进行滤波和分割。通过测量不同皮肤疾病所获得的图像的熵,验证了所提出工作的有效性。该性能在70个样本的数据集上进行了测试,这些样本来自150个不同身体部位的医学图像,包含10种不同类型的皮肤病。

Research on channel estimation algorithm of MIMO relay system based on PARAFAC model 基于PARAFAC模型的MIMO中继系统信道估计算法研究
Kuiyuan Zhang, Jianping Li, E. J. Guo
For the semi-blind estimation problem of two-hop multi-input multi-output amplified forwarding (MIMO-AF) relay system, the parallel factor (PARAFAC) model is constructed for the received signal. Using the uniqueness of its decomposition, an ALS-LS algorithm is proposed. Based on the algorithm of least squares alternating (ALS) and adding relaxation factor, the ALS algorithm is used to achieve certain convergence conditions. The estimation result of the former algorithm is taken as the initial value, and then based on the ALS algorithm adding relaxation factor, using the relaxation factor to change the gradient direction, so as to speed up the convergence rate. And the performance of the channel model is analyzed by different parameters of the channel model. Simulation results show: compared with the existing least squares alternate algorithm, the complexity and iteration times of the algorithm are reduced, and the convergence speed of the algorithm is accelerated.
针对两跳多输入多输出放大转发(MIMO-AF)中继系统的半盲估计问题,建立了接收信号的并行因子(PARAFAC)模型。利用其分解的唯一性,提出了一种ALS-LS算法。该算法在最小二乘交替(ALS)算法的基础上,加入松弛因子,达到一定的收敛条件。将前一种算法的估计结果作为初始值,然后在ALS算法的基础上加入松弛因子,利用松弛因子改变梯度方向,从而加快收敛速度。并通过信道模型的不同参数对信道模型的性能进行了分析。仿真结果表明:与现有的最小二乘交替算法相比,该算法降低了算法的复杂度和迭代次数,加快了算法的收敛速度。

Anti social comment classification based on kNN algorithm 基于kNN算法的反社会评论分类
Nidhi Chandra, S. Khatri, S. Som
Billions of contributions are made every day across multiple online communities and social media websites in the form of social messages, social blogs and online discussion. The aim of this paper is to identify such comments and posts which are racist and malicious in nature so that they could be effetely banned and removed in order to counter them. This article uses set of documents with racist comments as text corpus on which appropriate machine learning algorithm is applied to detect racist comments or meaning. To detect anti-social content there is a need to find the extent of similarity between a pair of text messages as a source and classified terms which are antisocial or in discriminating terms. The approach devised in this article to detect antisocial behavior is a technique based on term frequency based content classification.

An adaptive neuro-fuzzy inference system for detecting redirection spam 一种用于重定向垃圾邮件检测的自适应神经模糊推理系统
Kanchan Hans, Laxmi Ahuja, S. K. Muttoo
Redirection spam detection is important to maintain the integrity of information on World Wide Web. It is of prime interest to search engines for quality information retrieval. Malicious redirections break the trust of users and create unusual traffic leading to wastage of expensive bandwidth and other resources. But detecting redirections is complicated owing to the genuine use of redirections for load balancing and URL shortening. Present work addresses this problem of malicious redirections and proposes an adaptive neuro-fuzzy model (ANFIS) for its detection. The model takes five input features and uses hybrid algorithm for learning. We also employ subtractive clustering technique to reduce the training time so as to facilitate the quick decision making. The proposed model is tested and validated using datasets. The experimental results indicate that the model detects redirection spam with high accuracy. Therefore, the proposed model can be used as an effective approach for redirection spam detection.
重定向垃圾邮件检测对于维护万维网上信息的完整性非常重要。高质量的信息检索是搜索引擎最关心的问题。恶意的重定向会破坏用户的信任,产生不寻常的流量,导致昂贵的带宽和其他资源的浪费。但是检测重定向是复杂的,因为重定向真正用于负载平衡和URL缩短。目前的工作解决了恶意重定向问题,并提出了一种自适应神经模糊模型(ANFIS)用于其检测。该模型采用5个输入特征,并采用混合算法进行学习。我们还采用了减法聚类技术来减少训练时间,从而便于快速决策。使用数据集对所提出的模型进行了测试和验证。实验结果表明,该模型检测重定向垃圾邮件的准确率较高。因此,该模型可以作为一种有效的重定向垃圾邮件检测方法。

It is of prime interest to search engines for quality information retrieval. Malicious redirections break the trust of users and create unusual traffic leading to wastage of expensive bandwidth and other resources. But detecting redirections is complicated owing to the genuine use of redirections for load balancing and URL shortening. Present work addresses this problem of malicious redirections and proposes an adaptive neuro-fuzzy model (ANFIS) for its detection.
