In this paper, a textile terahertz reduced ground microstrip patch antenna for detection of trinitrotoluene (TNT) has been proposed. The proposed antenna is employing black denim as substrate having dielectric constant of εr = 1.6. The design and simulation of antenna has been carried out using CS T Microwave Studio 2014. The ground and patch of the proposed antenna has been designed using copper of thickness 0.05μm. It has been analyzed that the proposed antenna has impedance bandwidth of 247 GHz with an operating frequency range of 8.0481THz-8.3321THz with resonant frequency of 8.208 THz. It has been observed that the textile terahertz reduced ground microstrip patch antenna has gain of 7.359 dB and directivity of 7.002 dBi. The proposed antenna has minimal return loss of −65.89 dB at resonant frequency of 8.208 THz. The proposed antenna can be suitably employed for the detection of the TNT explosives and drugs.

Ultra high sensitive digital electromagnetic balance for measurement of weights in microgram: Design and experimentation 用于测量微克重量的超高灵敏度数字电磁天平:设计与实验
Swati B. Survase, Praveen V. Pol, Rajendra Patel
This paper proposes design of a weight measurement system capable of measuring weight in the range of micrograms to milligrams. The configuration of the system resembles with a conventional straw balance. Unlike straw balance the proposed system employs a force overcome technique. It does not employ any spring as that in case of other types of electromagnetic balance and any vibrating element present in some of the micro-weight measurement technique. The measurement system is digitally controlled using a microcontroller with digital display of measurement. Due to the light weight and extremely low friction, the proposed system becomes the highly sensitive, which can respond to weights in microgram level. The design comprises of a thin aluminum wire as a straw which is suspended by a fine wire and bearing arrangement. A micro-weighing pan is attached to one tip of the wire and a small iron piece is connected to other tip of the wire beneath which a small electromagnet is placed. The unknown weight in micro-weighing pan exerts a force at its end which is overcome by the electromagnetic force exerted on the iron piece present at the other end. Thus the force required to overcome the counterforce exerted by the unknown weight becomes a measure of unknown weight. When the force is overcome the pan is lifted and sensed optically. The electromagnetic force is proportional to the electromagnetic coil current which is again proportional to the DAC output, and hence the digital input of the DAC becomes the measure of the unknown weight. The proposed system was designed and practically implemented for the realization.
本文提出了一种能够测量微克到毫克范围内的重量的重量测量系统的设计。该系统的结构类似于传统的吸管天平。与秸秆平衡不同,该系统采用了一种力克服技术。它不像其他类型的电磁天平那样使用任何弹簧,也不像某些微重测量技术中存在任何振动元件。该测量系统采用带有数字显示的单片机进行数字控制。由于该系统重量轻,摩擦极小,因此具有很高的灵敏度,可以对微克级的重量进行响应。该设计包括一根细铝丝作为吸管,由细铝丝和轴承装置悬挂。一个微型称重盘连接在导线的一端,一个小铁片连接在导线的另一端,铁片下面放置一个小电磁铁。微称锅中的未知重物在其一端施加的力被施加在另一端铁片上的电磁力所克服。因此,克服未知重量所施加的反力所需的力就成为未知重量的度量。当力被克服时,锅被举起并通过光学检测。电磁力与电磁线圈电流成正比,而电磁线圈电流又与DAC输出成正比,因此DAC的数字输入成为未知重量的度量。为此设计了系统并进行了实际实现。

Monika Srivastava, Bhupendra Singh
In this paper analysis of Digital audio broadcasting on its four different modes have been performed. All the possible four modes have been executed and simulated on SIMULINK platform under different types of modulation schemes and channels. This paper is trying to develop a novel scheme of low cost, complexity wise reduced communication model for open air performance analysis. Thus the paper implements a novel method for the purpose of quality improvement in the communication equipment improvement using DAB. The results that have been performed on different types of channels are additive white Gaussian noise, Rayleigh and Rician fading channels. Similarly different modulation schemes in the model for example BPSK, QPSK, 16 QAM on different channels has been done. Of all the different types of channels in MATLAB & SIMULINK software for which a complete detailed table analysis has been done has found that of all the possible four modes the fourth mode has outperformed with good level of BER performance ranging between 20% to 22%. This paper has shown that with QPSK and AWGN Rayleigh channel mode 4 has proved to be the best working mode.

Particle swarm optimization algorithm and its parameters: A review 粒子群优化算法及其参数研究进展
Mudita Juneja, S. K. Nagar
In the year 1995, Dr R.C. Eberhart, who was an electrical engineer, along with Dr. James Kennedy, a social psycologist invented a random optimization technique which a was later named as Particle Swarm Optimization. As the name itself asserts that this method draws inspiration from natural biotic life of swarms of flocks. It uses the same principle to find most optimal solution to problem in search space as birds do find their most suitable place in a flock or insects do in a swarm. The PSO algorithm is initialized with a horde of particles which are a collection of random feasible solutions. Every single particle in the swarm is initialised a random velocity and as soon as they are assigned a velocity these particles start moving in problem search space. Now from this space the algorithm draws the particle to most suited fitness which in turn pulls it to the location of best fitness achieved across the whole horde. The PSO update rule comprises of many distinguishing features which are adjusted and modified depending upon the area of application of algorithm. This paper gives a detailed description of the PSO algorithm and significance of the various parameters involved in its update rule. It also highlights the advantages and disadvantages of using PSO algorithm in any optimization problem.
1995年,电子工程师R.C. Eberhart博士和社会心理学家James Kennedy博士一起发明了一种随机优化技术,后来被命名为粒子群优化。正如名字本身所言,这种方法的灵感来自于成群结队的自然生物。它使用与鸟类在鸟群中找到最合适的位置或昆虫在蜂群中找到最合适的位置相同的原理来寻找问题的最优解决方案。粒子群算法初始化为一群随机可行解的集合。群中的每个粒子都初始化了一个随机速度,一旦它们被分配了一个速度,这些粒子就开始在问题搜索空间中移动。现在,从这个空间中,算法将粒子绘制到最适合的适应度,然后将其拉到整个种群中获得最佳适应度的位置。粒子群更新规则由许多特征组成,这些特征可以根据算法的应用领域进行调整和修改。本文详细介绍了粒子群算法及其更新规则中涉及的各个参数的意义。同时强调了在任何优化问题中使用粒子群算法的优缺点。

Chandra Bhan, Anil Kumar, Arvind Kumar Jaiswal, Ajay Kumar Dwivedi
The microstrip patch antenna modiflcations have been being conducted over approximately four decades by different simulation tools. In this paper, an elliptical microstrip antenna (EMSA) is considered as a reference one and the introduction of an F-cut on it has brought improvements in the various parameters in both the operating bands with the centre frequencies of 3.6 GHz (S-Band) and 5.3 GHz (C-Band) covering the wireless interoperability microwave access (WiMAX) and wireless local area network (WLAN) fields respectively. The put forth elliptical patch antenna at Rogers RT /duroid 5880 simulated by HFSS 13 can be used for the wireless fidelity (WiFi) applications also. The proposed antenna has exhibited the return losses of −36.5 dB and −23 dB and the wider radiation pattern with the maxima of field strength being approximated 24 dB and 21.83 dB with appreciable gain of 6.3 dB and 4.1dB at 3.6 GHz and 5.3 GHz, respectively.

Comparative research of various adaptive algorithms for noise cancellation in speech signals 语音信号中各种自适应噪声消除算法的比较研究
Aniket Kumar, Pankaj Goel, V. Gupta, M. Chandra
In real life situations, the statistical characteristics of signal and noise are generally unknown & hence a digital filter having ‘constant coefficients’ is hardly of any use. In such situations adaptive filter is desirable. Adaptive filters are capable of adapting their filter coefficients as per the abnormality in characteristics of input signal and noise to achieve a noise free signal. This paper discusses the comparative analysis of various adaptive filter algorithms such as LMS (Least mean square), BLMS (Block LMS), NLMS (Normalized LMS), BNLMS (Block NLMS), VSLMS (Variable step size LMS) and BVSLMS (Block VSLMS) algorithms. As a input we have used Hindi audio speech signal and Babble noise as an interference signal.
在现实生活中,信号和噪声的统计特性通常是未知的,因此具有“常系数”的数字滤波器几乎没有任何用处。在这种情况下,自适应滤波器是可取的。自适应滤波器能够根据输入信号和噪声特性的异常调整滤波器系数,从而获得无噪声的信号。本文讨论了LMS (Least mean square)、BLMS (Block LMS)、NLMS (Normalized LMS)、BNLMS (Block NLMS)、VSLMS (Variable step size LMS)和BVSLMS (Block VSLMS)算法等各种自适应滤波算法的比较分析。作为输入,我们使用印地语音频语音信号和Babble噪声作为干扰信号。

Rochelle salt integrated PIR sensor arduino based intruder detection system (ABIDS) 基于arduino的Rochelle salt集成PIR传感器入侵检测系统(ABIDS)
S. Saini, H. Bhatia, Vatanjeet Singh, Ekambir Sidhu
In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle salt based sensor and PIR sensor supervised simultaneously by Arduino UNO. The Rochelle salt (Potassium Sodium Tartrate) exhibits piezoelectric properties in response to applied mechanical stress. The PIR sensor responds to Infrared (IR) radiating objects moving in its viewing range. The PIR detection is done by creating temporary electric potential whenever a change in IR radiations occurs within the viewing range of the sensor. The Rochelle salt and PIR sensor work independent of each other. The novelty of the system lies in its utilization of the Rochelle salt as sensing element for security purposes. The 20 grams of powder Rochelle salt is capable enough to generate 290mV. When the intruder enters the restricted area, the sensors sense the intruder and an alarm is triggered. In case, if one of the sensors stops working, it doesn't affect the working of the other sensor. The time variation of the buzzer helps in recognizing how far the intruder is from the restricted area.
本文提出了一种基于Arduino的基于Rochelle Salt和无源红外(PIR)传感器的入侵者检测系统。该系统采用Rochelle盐基传感器和PIR传感器,由Arduino UNO同时监督。Rochelle盐(酒石酸钾钠)在响应施加的机械应力时表现出压电特性。PIR传感器响应红外(IR)辐射物体在其观察范围内移动。PIR检测是通过在传感器的观察范围内每当红外辐射发生变化时产生临时电势来完成的。罗谢尔盐和PIR传感器彼此独立工作。该系统的新颖之处在于它利用罗谢尔盐作为安全目的的传感元件。20克的罗谢尔盐粉末足以产生290毫伏的电压。当入侵者进入限制区域时,传感器感应到入侵者并触发警报。如果其中一个传感器停止工作,则不会影响另一个传感器的工作。蜂鸣器的时间变化有助于识别入侵者离限制区域的距离。

Combining hybrid information descriptors and DCT for improved CBIR performance 结合混合信息描述符和DCT提高CBIR性能
V. Singh, Shivoam Malhotra, R. Srivastava
Content Based Image Retrieval (CBIR) aims to retrieves images in the database that are similar to a query image based on the contents of the image rather than metadata. The algorithm used to extract features from images is one of the most influential factors towards a CBIR system's performance. In this paper, we take a look at hybrid information descriptors (HID) as the feature extraction algorithm for our CBIR system and supplement HID with information in the compressed domain using discrete cosine transform (DCT). The HID+DCT algorithm proposed was compared with the HID algorithm on the Corel Dataset. We found out that the HID+DCT algorithm performs better than HID algorithm. We have used and compared Manhattan Distance and Euclidian Distance as distance metrics during the process of feature matching and observed that Manhattan Distance gave the best precision value for HID+DCT feature. However, the use of DCT results in a larger feature vector size which could potentially lead to slow queries. We consider using minimal-redundancy-maximal-relevance criterion (mRMR) for feature selection to reduce the size of feature vector to avoid speed related issues. We observe that the difference in precision for a feature vector reduced to almost the same size as HID's feature vector and HID+DCT is negligible.
基于内容的图像检索(CBIR)旨在根据图像的内容而不是元数据检索数据库中与查询图像相似的图像。从图像中提取特征的算法是影响CBIR系统性能的主要因素之一。本文将混合信息描述符(HID)作为我们的CBIR系统的特征提取算法,并使用离散余弦变换(DCT)在压缩域中补充HID信息。在Corel数据集上将提出的HID+DCT算法与HID算法进行了比较。结果表明,HID+DCT算法的性能优于HID算法。在特征匹配过程中,我们使用Manhattan Distance和Euclidian Distance作为距离度量并进行了比较,发现Manhattan Distance为HID+DCT特征提供了最好的精度值。然而,使用DCT会导致更大的特征向量大小,这可能会导致查询速度变慢。我们考虑使用最小冗余最大相关准则(mRMR)进行特征选择,以减小特征向量的大小,避免与速度相关的问题。我们观察到,将特征向量缩小到与HID的特征向量和HID+DCT几乎相同的大小,其精度差异可以忽略不计。

We have used and compared Manhattan Distance and Euclidian Distance as distance metrics during the process of feature matching and observed that Manhattan Distance gave the best precision value for HID+DCT feature. However, the use of DCT results in a larger feature vector size which could potentially lead to slow queries. We consider using minimal-redundancy-maximal-relevance criterion (mRMR) for feature selection to reduce the size of feature vector to avoid speed related issues. We observe that the difference in precision for a feature vector reduced to almost the same size as HID's feature vector and HID+DCT is negligible.","PeriodicalId":410488,"journal":{"name":"2016 International Conference on Control, Computing, Communication and Materials (ICCCCM)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134521541","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}

Hybrid renewable energy system integration in the micro-grid: Indian context 微电网中的混合可再生能源系统集成:印度背景
O. Singh, Arif Iqbal, Sanjeev Kumar, S. K. Rajput
Electricity production from renewable energy sources (RESs) can be attractive, efficient and pollution free idea for remote locations in India. For remote locations domestic load, RESs that can be solar, wind, small hydro and biomass considered for a trustworthy alternative to reducing the dependency on fossil fuels. Due to the variance in the electric output of RESs, these can't be operated smoothly without integration in the micro-grid. So, integration of RESs is necessary for system operators. Therefore, hybrid renewable energy system (HRES) can be counted to cope up with irregular electric supply and transmission lines problems in remote areas. Moreover, HRES integration into the micro-grid can reduce dependency on main-grid supply and also improve reliability of electricity. However, HRES can create problems when their execution is attempted to be realistic. So, hilly remote areas HRES integration into the micro-grid is a great challenge to Power Engineers. Therefore, a comprehensive analysis on HRES and micro-grid technical as well as commercial issues and challenges is presented in this article.
对印度偏远地区来说,利用可再生能源发电可能是一个有吸引力、高效和无污染的想法。对于偏远地区的家庭负荷,RESs可以是太阳能、风能、小水电和生物质能,被认为是减少对化石燃料依赖的可靠替代方案。由于RESs的输出电量存在差异,如果不整合到微电网中,就无法顺利运行。因此,对系统运营商来说,集成RESs是必要的。因此,混合可再生能源系统(HRES)可以用来解决偏远地区不稳定的电力供应和输电线路问题。此外,将HRES并入微电网可以减少对主网供电的依赖,提高电力的可靠性。然而,当HRES的执行试图切合实际时,可能会产生问题。因此,将丘陵偏远地区的HRES并入微电网对电力工程师来说是一个巨大的挑战。因此,本文将对HRES和微电网的技术以及商业问题和挑战进行全面分析。

Securing association rule mining with FP growth algorithm in horizontally partitioned database 用FP增长算法保护水平分区数据库中的关联规则挖掘
Vaishali Patil, Ramesh Vasappanavara, T. Ghorpade
Data mining examines large pre-existing databases in order to generate new information. There are various tasks included under Data mining and association rule mining is considered as one of the crucial tasks among its. They are in form of if-then kind of statements which help to find relationships among huge data which do not hold relationship with each other within a relational database or any other information repository. As there are many applications like market basket analysis, detection of fraud in web, medical diagnosis, census data, Customer Relationship Management of credit card business which uses association rules so it is possible to improve the process of Decision making. Security is required for individual transaction and for frequent itemsets when the database is partitioned horizontally among multiple sites. In this case, every site is interested in globally supported association rules without revealing its own local information. To fulfill this goal, We use a secure multi-party algorithm based on secure sum technique to simplify the operation of mining association rule when the database is horizontally partitioned among multiple sites. We are using a Frequent-Pattern (FP) growth algorithm to find frequent itemsets and try to reduce total computation time.
数据挖掘检查大型预先存在的数据库,以生成新的信息。数据挖掘包含多种任务,关联规则挖掘是其中的关键任务之一。它们以if-then类型的语句的形式存在,这些语句有助于在关系数据库或任何其他信息存储库中发现彼此之间没有关系的大量数据之间的关系。由于在信用卡业务的市场购物篮分析、网络欺诈检测、医疗诊断、人口普查数据、客户关系管理等许多应用中都使用了关联规则,因此可以改进决策过程。当数据库在多个站点之间水平分区时,单个事务和频繁的项集需要安全性。在这种情况下,每个站点都对全局支持的关联规则感兴趣,而不会透露自己的本地信息。为了实现这一目标,我们使用了一种基于安全和技术的安全多方算法来简化数据库在多个站点之间水平分区时关联规则挖掘的操作。我们使用频率模式(FP)增长算法来查找频繁项集,并尝试减少总计算时间。
