A novel procedure to detect Interstitial Lung Disease (ILD) with High Resolution Computed Tomography (HRCT) images is proposed. Seven texture measures from a selected slice of HRCT lung image of fifteen ILD cases, fifteen non-ILD cases and fifteen healthy individuals were obtained and their pairwise correlation calculated. Two groups of texture measure obtained from standard clustering procedure were then used to create a discrimination procedure using simple linear regression. The texture measure Contrast and Standard Deviation of Energy (STDE) gave the highest detection rate.

A great revolution in health science could be done if the disease could be diagnosis at very early stage. The conventional chemically manipulated biological analysis of group cells is not able to illustrate the fundamental properties of a cell such as cell proliferations, cell growths, cell damage and electro-mechanical properties. In this paper, we are representing a method to measure the mass of a single cell using the deformation of a nanofork (which will pick the cell form a line array substrate). We have used Newton's third law related with the deformation angle caused by the moment of inertia (as the fork will bend downward). Silicon is used as a base material of the nanofork. Firstly, the nanofork is inserted into the line array substrate then it picks up the cell to the upwards creating a deformation of the nanofork because of the cell weight. Then deformation angle is calculated form simulation result. For the experimental purpose we have used cell size is 5 µm. We observed the deformation angle 0.4 µm form the simulation result. Which is sufficient to find out the mass of the cell. Using the deformation angle and the related equations we have measured the mass of a single cell 0.16 pg. This result is very consistent with the previously reported single yeast cell mass.
如果这种疾病能在早期被诊断出来,那将是健康科学的一场伟大革命。传统的化学操作的群体细胞的生物分析不能说明细胞的基本特性,如细胞增殖,细胞生长,细胞损伤和机电特性。在本文中,我们代表了一种方法来测量单个细胞的质量,使用纳米叉子的变形(它将挑选细胞形成线阵列衬底)。我们使用了牛顿第三定律,该定律与惯性矩引起的变形角有关(因为叉子会向下弯曲)。硅被用作纳米叉子的基础材料。首先,纳米叉子被插入到线阵列衬底中,然后它向上拾取细胞,因为细胞的重量而产生纳米叉子的变形。然后根据仿真结果计算变形角。出于实验目的,我们使用的电池尺寸为5µm。模拟结果显示变形角为0.4µm。这就足以求出细胞的质量。利用变形角和相关方程,我们测量了单个酵母细胞的质量为0.16 pg,这一结果与之前报道的单个酵母细胞质量非常一致。

In this paper we draw attention to the emerging field of smart material interfaces. These novel composites, that in some cases are already celebrated as the answer for the 21st century's technological needs, are generally referred to as materials that are capable of sensing the environment and actively responding to environmental changes by changing their physical properties. Smart materials have physical properties that can be changed or controlled by external stimuli such as electric or magnetic fields, light, temperature or stress. Shape, size and color are among the properties that can be changed. Smart material interfaces are physical interfaces that utilize these materials to sense the environment and display responses by changing their physical properties. Common smart materials appear in the form of polymers, ceramics, memory shape alloys or hydro-gels. This paper aims at stimulating research and development in interfaces that make novel use of such smart materials.

Handwritten character recognition is an active area of research with applications in numerous fields. Past and recent works in this field have concentrated on various languages. Arabic is one language where the scope of research is still widespread, with it being one of the most popular languages in the world and being syntactically different from other major languages. Das et al. [1] has pioneered the research for handwritten digit recognition in Arabic. In this paper, we propose a novel algorithm based on deep learning neural networks using appropriate activation function and regularization layer, which shows significantly improved accuracy compared to the existing Arabic numeral recognition methods. The proposed model gives 97.4 percent accuracy, which is the recorded highest accuracy of the dataset used in the experiment. We also propose a modification of the method described in [1], where our method scores identical accuracy as that of [1], with the value of 93.8 percent.

Detection of corner is the most essential process in a large number of computer vision and image processing applications. We have mentioned a number of popular contour-based corner detectors in our paper. Among all these detectors chord to triangular arm angle (CTAA) has been demonstrated as the most dominant corner detector in terms of average repeatability. We introduce a new effective method to calculate the value of curvature in this paper. By demonstrating experimental results, our proposed technique outperforms CTAA and other detectors mentioned in this paper. The results exhibit that our proposed method is simple yet efficient at finding out corners more accurately and reliably.

In this paper, a novel adaptive digital image watermarking model based on modified Fuzzy C-means clustering is proposed. For watermark embedding process, we used Discrete Wavelet Transform (DWT). A segmentation technique XieBeni integrated Fuzzy C-means clustering (XFCM) is used to identify the segments of original image to expose suitable locations for embedding watermark. We also pre-processed the host image using Particle Swarm Optimization (PSO) to lend a hand to the clustering process. The goal is to focus on proper segmentation of the image so that the embedded watermark can withstand common image processing attacks and provide security to digital images. Several attacks were performed on the watermarked images and original watermark was extracted. Performance measures like PSNR, MSE, CC were computed to test the extracted watermarks with and without attacks. Experimental results show that the proposed scheme has performed well in terms of imperceptibility and robustness when compared to other watermarking models.

Electrocardiogram (ECG) is a test that represents electrical activity of heart and plays an important role in monitoring the condition of the heart. The diagnosis of cardiac condition is greatly dependent upon ECG signals. This paper presents a method of feature extraction and characterization of ECG signals for normal sinus rhythm and three different types of cardiovascular arrhythmia, namely Slow Term Atrial Fibrillation, Paroxysmal Atrial Fibrillation and Supraventricular Tachycardia. The proposed algorithm is implemented using NI LabVIEW Biomedical Workbench to perform signal processing that extracts features of ECG signal such as heart rate, QRS width, PR interval, QT interval and the RR interval which are then used to characterize both cardiovascular arrhythmia and normal sinus rhythms. About Forty-five sets of data of ECG signals are used in this work for analysis and verification and satisfactory result is obtained.

There are many conventional methods for book detection and title recognition from bookshelf images. But most of these methods are worked on single row bookshelf images. Here this paper presents a technique for segmenting books spine and recognizing book title from multi-row bookshelf images. Horizontal edges are detected and extracted from the images as to indicate individual rows. These separated row images are used in the next module where vertical lines are extracted in order to segment the book regions. Later all book spine images are converted into binary images. At the next step, small and unwanted objects are removed using region properties and subsequently and extracts titles from individual book spines. Then the characters of the title are segmented and extracted by using bounding box and connected component region. Separated character images are matched or unmatched with the data set images by applying template matching. As a result, the developed new method recognizes the title. The system design as a whole makes a contribution, but the extraction of the book titles from the multi-cell images makes the main principal of this paper. To test the proposed framework various bookshelf images with a variety of conditions are used and results are presented to prove its effectiveness.
从书架图像中进行图书检测和标题识别的传统方法有很多。但这些方法大多是在单行书架图像上工作的。本文提出了一种从多行书架图像中分割书脊并识别书名的技术。从图像中检测和提取水平边缘以指示单个行。这些分隔行图像将在下一个模块中使用,其中提取垂直线以分割图书区域。随后,所有书脊图像都被转换成二值图像。在下一步,使用区域属性删除小的和不需要的对象,然后从单个书脊中提取标题。然后利用边界框和连通分量区域对标题字符进行分割和提取。通过应用模板匹配,将分隔字符图像与数据集图像进行匹配或不匹配。因此,开发的新方法可以识别标题。系统的整体设计起到了一定的作用,但从多单元图像中提取图书标题是本文的主要内容。为了测试所提出的框架,使用了不同条件下的书架图像,并给出了结果来证明该框架的有效性。

Reconstruction of gene network through Backward Elimination based Information-Theoretic Inference with Maximal Information Coefficient 基于最大信息系数的逆向消去信息推理的基因网络重构

For understanding the complex processes of regulation within the system of cellular and every process of life in different developmental and environmental contexts, reconstructing Gene Regulatory Networks(GRNs) is an essential part of Systems Biology. A recently developed maximal information coefficient (MIC) is better to detect all kinds of association than others and it maintains both generality and equitability properties. In this study, we combined MIC as an entropy estimator with gene regulatory network method Backward Elimination based Information-Theoretic Inference and then compare this proposed method with the MI-based algorithm MRNETB by examining SynTReN's datasets. The performance of our proposed MIC based MRNETB (MRNETB-MIC) is given by using both the receiver operator characteristic (ROC) curve and the precision-recall (PR) curve and from these, the proposed method shows significantly better performance in reconstructing gene regulatory network.
为了理解细胞系统内的复杂调控过程以及不同发育和环境背景下的生命过程,基因调控网络(GRNs)的重构是系统生物学的重要组成部分。最近提出的最大信息系数(MIC)能较好地检测各种关联,并保持了通用性和公平性。在这项研究中,我们将MIC作为熵估计器与基因调控网络方法相结合,然后通过检查SynTReN的数据集,将该方法与基于mi的MRNETB算法进行比较。我们提出的基于MIC的MRNETB (MRNETB-MIC)的性能通过使用接收算子特征(ROC)曲线和精确召回率(PR)曲线给出,从这些方面来看,我们提出的方法在重建基因调控网络方面表现出明显更好的性能。

A recently developed maximal information coefficient (MIC) is better to detect all kinds of association than others and it maintains both generality and equitability properties. In this study, we combined MIC as an entropy estimator with gene regulatory network method Backward Elimination based Information-Theoretic Inference and then compare this proposed method with the MI-based algorithm MRNETB by examining SynTReN's datasets. The performance of our proposed MIC based MRNETB (MRNETB-MIC) is given by using both the receiver operator characteristic (ROC) curve and the precision-recall (PR) curve and from these, the proposed method shows significantly better performance in reconstructing gene regulatory network.","PeriodicalId":126745,"journal":{"name":"2017 IEEE International Conference on Imaging, Vision & Pattern Recognition (icIVPR)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132720510","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}

The features of underwater wireless sensor networks are different from those found in the terrestrial ones, while their architecture is penetrable to several issues such as huge propagation delays, limited bandwidth, and multiple messages receptions due to reflections on the sea surface. It also depends on the flexibility of floating sensor nodes. Underwater sensor network has flowed as a powerful technique for aquatic applications. A Sleep Scheduling strategy is a feasible scheme built on tree topology combining TDMA with duty-cycling. Hence TDMA has time slots, so here is no data collision in this network. ROSS, a Receiver Oriented Sleep scheduling strategy use TDMA based on tree topology. But they have not given any solution to the Energy hole problem. They have no data recovery option, if any node has missed data when they die. In this paper we have proposed a mechanism to save transaction time compare to traditional UWSNs MAC protocol.
水下无线传感器网络具有不同于地面无线传感器网络的特点,但其结构可穿透传输延迟大、带宽有限以及海面反射导致的多信息接收等问题。它还取决于浮动传感器节点的灵活性。水下传感器网络已成为一种强有力的水下应用技术。睡眠调度策略是一种建立在树形拓扑结构上的将时分多址和占空循环相结合的可行方案。因此TDMA有时隙,所以在这个网络中没有数据冲突。ROSS是一种基于树形拓扑结构的面向接收器的睡眠调度策略。但是他们没有给出任何解决能量洞问题的方法。它们没有数据恢复选项,如果任何节点在它们死亡时丢失了数据。与传统的UWSNs MAC协议相比,本文提出了一种节省交易时间的机制。
