The most the most dangerous cancer is colon cancer. The premature version of this type of cancer is the colon polyp. The death ration for this type of cancer is almost 10:9.2 for men: women [1]. Only one prevention of this is the very early diagnosis. In this paper a robust and novel work is proposed for detecting this colon cancer using Discrete Wavelet Transform (DWT). For this detection two sets of videos are taken from American College of Gastroenterology [3], actually these two videos are fissure into number of image samples. A novel Wavelet Transform is applied on each image sample followed by edge detection technique using Otsu edge detection process. For extracting the features of those images Principle Component Analysis (PCA) is executed for reduction of the features. A potent classification, Synthesize Similarity Measure (SSM) algorithm is opted for the classifying the disease. This fast and ameliorated process (DWT_SSM) gives the best result (almost 99.1% best result, 98.82% average result) when comparing with other benchmark and conventional procedures.
最危险的癌症是结肠癌。这种癌症的早期版本是结肠息肉。这类癌症的死亡率在男性和女性中几乎是10:9.2[1]。唯一的预防方法就是早期诊断。本文提出了一种基于离散小波变换(DWT)的结肠癌检测方法。为了进行检测,我们从美国胃肠病学学会[3]获取了两组视频,实际上这两组视频是被分割成多个图像样本的。对每个图像样本进行小波变换,然后采用Otsu边缘检测技术进行边缘检测。在提取图像特征时,采用主成分分析(PCA)对特征进行约简。一种有效的分类方法——综合相似度度量(SSM)算法被用于疾病分类。与其他基准和常规程序相比,这种快速改进的过程(DWT_SSM)提供了最佳结果(几乎99.1%的最佳结果,98.82%的平均结果)。

Automatic mixed pixel detection using a new hybrid Cellular automata approach on satellite image 基于混合元胞自动机的卫星图像混合像素自动检测
K. Mahata, R. Das, Subhasish Das, Anasua Sarkar
Mixed-pixels classification in land-cover regions is a challenging task in remote sensing imagery. To classify mixed-pixels, vagueness is always the main characteristic by handling uncertainty. We propose a hybrid approach for pixel classification using Rough sets and Cellular automata models to solve this problem. Multiple belongingness and vagueness among data can be handled efficiently using Rough set theory and is appropriate for detecting arbitrarily-shaped clusters in satellite images. We propose a rough-set based automatic heuristically decision-rule generation algorithm to obtain initial set of clusters. As a discrete, dynamical system, cellular automaton comprises of uniformly interconnected cells with states. In the second phase of our method, we utilize a 2-dimensional cellular automaton to prioritize allocations of mixed pixels among overlapping land cover regions. We experiment our algorithm on Ajoy river catchment area. The segmented regions are compared with well-known FCM and K-Means methods and the ground truth knowledge, which shows superiority of our new approach.
土地覆盖区域的混合像元分类是遥感影像中一个具有挑战性的课题。在混合像素分类中,模糊性是处理不确定性的主要特征。我们提出了一种使用粗糙集和元胞自动机模型的混合像素分类方法来解决这个问题。粗糙集理论可以有效地处理数据间的多重归属性和模糊性,适用于卫星图像中任意形状聚类的检测。提出了一种基于粗糙集的自动启发式决策规则生成算法来获取初始聚类集。元胞自动机是一个离散的动态系统,由具有状态的均匀互连的单元组成。在我们的方法的第二阶段,我们利用二维元胞自动机来优先分配重叠的土地覆盖区域之间的混合像素。我们在阿乔伊河集水区试验了我们的算法。将分割的区域与已知的FCM和K-Means方法以及地面真值知识进行比较,表明了新方法的优越性。

Generating dark solution inside fiber Bragg grating structure for hermite-Gaussian input wave 隐高斯输入波在光纤布拉格光栅结构内产生暗解
P. Halder, A. Deyasi
Dark solution pulses inside fiber Bragg grating structures are generated and its shape after propagation are analytically computed for both appropriate phase shift (asymmetric pulse) and higher than that (symmetric pulse). Hermite-Gaussian pulse is considered as input one and different bandwidth of the grating structures are considered for passive filtering purpose to study the variation of soliton pulses inside the structure and after propagation. Effect of chromatic dispersion is analyzed on soliton pulses, and results are in excellent agreement with experimental findings. Breaking of pulses is also shown by varying the peak power of the input spectrum. Simulated observations will play key role for soliton-based communication systems.

M. Roy, S. Moitra
In this paper, design and analysis of a new type of Substrate Integrated Waveguide (SIW) antenna and a pair of inverted complimentary U-shaped slots are proposed with considerable effect of a single reflection cancelling via (RCV) at the center of the structure. The position of the complementary slots with respect to the RCV is varied for getting the resonant frequency within microwave x-bands (≈11 GHz) and the effect of these variations are presented in the form of parametric graphs. Elementary array of vias are used to enhance the return loss as well as the gain of the antenna. The proposed antenna is designed over FR4 substrate material of dielectric constant 4.4 and with a thickness of 1.6 mm using Ansoft HFSS Microwave CAD tool.

R.K. Sharma, P. Ganesan
In the present study, the phase change behavior of prepared novel composites of palmitic acid and nano titanium dioxide (TiO2) for thermal energy storage have been investigated. The nano-particles are dispersed into the base fluid in various mass fractions (0.5, 1, 3, and 5%) and their effects on the thermo-physical properties have been investigated. Structural analysis has been carried out by using FESEM and crystallography was checked by XRD technique. Thermal conductivity of palmitic acid increased gradually by 12.7, 20.6, 46.6, and 80% for the nano-particle weight fractions of 0.5, 1, 3, and 5% respectively. Based on the results, it can be mentioned that the prepared palmitic acid based nano-enhanced organic phase change composite materials can be very well used as potential solar thermal energy storage materials.

Balancing security & sharing of fitness trackers' data 平衡健康追踪器数据的安全性和共享
Renata Saha, Sayan Sarkar, S. K. Datta
Use of wearable fitness trackers is progressively increasing over the world. The raw information from these gadgets on processing produces Electronic Health Record (EHR). It has great importance since it enhances the scope of medicinal services with financially savvy nature. Despite this fact, the human health architecture are tested essentially by security and ownership of information. Securing EHR with an encoded secret key is a plausible choice. EHRs have their potential advantages in the Evidence Based Medicine (EBM). The purpose of this paper is to discuss the various ethical issues arising during use of the EHRs of fitness trackers and their possible solutions by strengthening security with gaining public trust on EHR based approach. This paper also proposes a filter system that balances the security & sharing of health data.

I-shaped dual-resonant gigahertz antenna for radiolocation and military applications 用于无线电定位和军事应用的i形双谐振千兆赫天线
Vishal Mehta, Avneet Kaur, Prince, Snigdha Vasudev, Ekambir Sidhu
The proposed paper presents two I-shaped substrate slotted flexible microstrip patch antennas with reduced ground for radiolocation and military applications. The proposed antennas employ cellulose acetate having dielectric constant (∊r) of 4.2 as the substrate. The copper having conductivity of 5.95 × 108 Siemens m−1 has been used for designing of patch and ground. The substrate, patch slot and ground reduction is employed to enhance the antenna parameters such as return loss, VSWR (Voltage Standing Wave Ratio) and bandwidth. The first antenna is resonant at 1.775 GHz and 3.46 GHz with the impedance bandwidth of 1.503 GHz where as the second antenna has resonant frequencies of 1.815 GHz and 3.345 GHz and impedance bandwidth of 1.570 GHz. The performance of proposed antennas has been analyzed in terms of gain(dB), directivity(dBi), return loss(dB), impedance bandwidth(GHz), VSWR(voltage standing wave ratio) and impedance(Ω). The proposed antennas have been fabricated and tested using E5071C Network analyser and anechoic chamber. It has been concluded that the practically tested results closely matches with the simulated results obtained in CST Microwave Studio 2016. Both the antennas can be effectively employed for radiolocation, aeronautical mobile communication, maritime mobile communication and military applications.

Theoretical analysis of fiber loop ringdown spectroscopy for gas sensing 气体传感用光纤环衰荡光谱的理论分析
Aparajeeta Guha, T. K. Gangopadhyay
The theoretical simulations related to fiber loop ring down spectroscopy (FLRDS) has been carried out for gas sensing. An analogy between optical system and the equivalent electrical circuit is depicted to simulate the response of the gas sensing system. In the second part, a set up for Carbon dioxide sensing mechanism is proposed using FLRDS.
对光纤环衰荡光谱(FLRDS)进行了气体传感的理论模拟。通过类比光学系统和等效电路来模拟气体传感系统的响应。第二部分提出了基于FLRDS的二氧化碳传感机制的构建。
