The microbial communities play a salient role in natural ecosystems and have a greater impact on animal and human health. To understand this entangled system and unlock its potential benefit there is need to study these community structures and function both analytically and statistically. This article briefs about the microbial community analysis R packages which are developed in R programming language, to assist researchers for creating abundance and functional profile from raw data and performs analyses specific to their needs. The analysis of biological data and information related to microbial community are known together to be the central issues within the space. Therefore several R packages are planned to perform a collective and complete interpretation of data using R modules in this area. In this paper we tend to present a bio-informative R package which can analyze the abundance of the species and determine the one way variance which is used as fdANOVA R package. The idea provides the straightforward categorical grouping, is custom-made to check the status of evolving microbes in a community and is appropriate and reliable as well.

Compromised accounts are of a severe risk to the social network users. People now a days are mostly dependent on Online Social Networks. While some persistent spams feat the relationship between the users by spreading spams. Therefore time to time detection of the compromised accounts is a necessity. In this paper, we will study different social user behaviour and detect the compromised accounts and spam users. Spam behaviour in social networks has a wide range of illegal activities. Such activities need to be evaluated and effect of spam users needs to be reduced. To reduce such effects, we require proper detection strategy. We validate the effectiveness of these behaviour by collecting the clickstream data on a social network website. Social behaviour reflects the users behaviour online. While an legitimate user coordinates its social behaviour carefully, it is hard for the fake users to pretend to be affected. Different studies are performed in spam behaviour analysis and define a structure for spam account detection.

A technique is presented to design dual-band, high-gain metamaterial based resonant cavity antenna using frequency selective surface (FSS) layer. The radiating dielectric resonator (DR) is connected by a microstrip line and a rectangular slot is cut from the ground surface. Cylindrical dielectric resonator antenna (CDRA) is used as an elementary radiator. CDRA is excited by the microstrip line through the rectangular slot and it is radiating in the broadside direction at two adjacent frequency bands (S and C bands). Antenna simulation results confirmed it resonates in two adjacent bands centered at 3.9 GHz and 7.1 GHz. The gain of the DRA at these two bands are 2.43 dBi and 4.32 dBi respectively. With a single layer 5 × 5 array superstrate the gain of the proposed antenna increased by 8.02 dBi from 3.6 to 4.1 GHz frequency band and 1.05 dBi from 6.7 to 7.5 GHz frequency band. This high-gain dual-band DRA can be used for millimeter wave wireless communication, small satellite communication terminals.

Facial expression analysis has a wide area of applications including health, psychology, sports etc. In this study, we explored different methods of automatic classification of exercise intensities using facial image processing of a subject performing exercise on a cycloergometer during an incremental standardized protocol. The method can be implemented in real time using facial video analysis. The experiments were done with images extracted from a 12 min HD video collected in laboratorial normalized settings (TechSport from the University of Trás-os-Montes e Alto Douro) with a static camera (90° angle with face and camera). The time slot for video to extract images for a particular class of exercise intensity is correspondence to the incremental heart rate. The facial expression recognition has been performed mainly in two steps: facial landmark detection and classification using the facial landmarks. Luxand application was used to detect 70 landmarks were detect using the adaptation of code available in Luxand application and we applied machine learning classification algorithms including discriminant analysis, KNN and SVM to classify the exercise intensities from the facial images. KNN algorithms presents up to 100% accuracy in classification into 2 and 3 classes. The distances between a lowermost landmark of the faces, which is indicated in landmark number 11 in the Luxand application, and the 26 landmarks around mouth were calculated and considered as features vector to train and test the classifier. Separate experiments were done for classification into two, three, and four classes and the accuracy of each algorithm was analyzed. From the overall results, classification into two and three classes was easy and resulted in very good classification performance whereas the classification with four classes had poor classification performance in each algorithm. Preliminary results suggest that distinguishing more levels of exertion, might require additional feature variables.
面部表情分析具有广泛的应用领域，包括健康、心理学、体育等。在这项研究中，我们探索了在增量标准化方案中，利用受试者在旋转计量器上进行运动的面部图像处理来自动分类运动强度的不同方法。该方法可以通过人脸视频分析实时实现。实验采用静态摄像机(面部与摄像机呈90°角)，从实验室标准化设置(Trás-os-Montes e Alto Douro大学的TechSport)收集的12分钟高清视频中提取图像。视频提取特定运动强度的图像的时间间隔与增量心率相对应。面部表情识别主要分为两个步骤:面部特征点检测和面部特征点分类。使用Luxand应用程序检测70个地标，使用Luxand应用程序中可用的代码进行自适应检测，并使用判别分析、KNN和SVM等机器学习分类算法对面部图像中的运动强度进行分类。KNN算法在2类和3类分类中呈现高达100%的准确率。计算人脸最下面的一个地标(在Luxand应用程序中标记号为11)与嘴巴周围的26个地标之间的距离，并将其作为特征向量来训练和测试分类器。分别进行了2类、3类和4类分类实验，并对每种算法的准确率进行了分析。从整体结果来看，两类和三类分类容易，分类性能很好，而四类分类在各算法中的分类性能都很差。初步结果表明，区分更多的运动水平，可能需要额外的特征变量。

Industrial automation systems play a crucial role in controlling several process- related operations. Due to the implementation of a wide variety of industrial networks with their geographical distribution over industry, the floor data transferring and controlling capability has become more sophisticated and the need for a reliable, fast, high level communication network arises which can be satisfied by Controller Area Network. Our proposed system implements the CAN protocol in Industrial Automation. In this system, a single node consists of various sensors which monitors and provides process variables to ATmega328 Microcontroller. This is then connected to a CAN controller which exchanges data with ATmega328 Microcontrollers using serial peripheral interface. CAN controller does the process of control, error management and bit stream conversion. This serial data is connected to the CAN transceiver for the CAN bus establishment. Many such nodes are connected to the CAN bus. On the other end of the bus, the master NXPlpc1768 which has inbuilt CAN ports receive and control the datas and process variables from the nodes by using CAN protocol. This master NXPlpc1768 is improvised with the inclusion of IoT which uses internet connectivity by using ethernet shield that sends datas and process variables from the remote location of the industry to the user at any geographical area.

IoT – a new proliferation in the technological advancement, changed the way object is perceived and used. It enables connecting smart objects to the internet and aims to develop new promising future to Intelligent Transportation System (ITS). ITS uses techniques such as wireless communication, computational technologies, GPS, and sensor technologies to provide smart and quick services to users and to be better informed and make safer, more coordinated, and 'smarter' use of transportation medium. As number of objects connected to ITS application increases, the amount of data generated also increases and they are send to cloud for data analysis and knowledge discovery. However, sending and retrieving of data across cloud is less useful due to delay latency and others. An alternative to cloud is fog (edge) model that overcomes the weakness of cloud by analyzing and discovering knowledge at the edge. However, the fog computing model has limited computational capability. For an IoT enabled Intelligent Transportation System with enormous number of objects connected, neither cloud nor fog computing model addresses the issues alone. This paper focuses on presenting an IoT hybrid model for Intelligent Transportation System (ITS). We also address the effectiveness of the model by discussing use case scenarios.

The demand for multilevel inverter have increased over time due to the high total harmonic distortion and unsatisfactory operation of conventional inverter. Cascaded H-bridge (CHB) multilevel inverter is simple, requiring fewer power components and more reliable than other types of topology so it is more preferable. But to increase the level of inverter output more number of components are required which makes more switching losses. So we are going toward asymmetrical topology which helps to get more number of levels with less number of power components. In this paper nine-level asymmetric CHB inverter is presented with eight power switches and two dc voltage sources of 1:3 proportion. The analysis is done for carrier scheme, amplitude index, and modulation index. Results are obtained with MATLAB Simulink software.

The users from the social networks like Facebook, Twitter etc. expecting that social networks can able to preserve their privacy. To address this, recently PRIGUARD framework introduced in which meta model and description logic used for describing the social network commitments and domain in order to specify the privacy needs of end users. This approach is able to detect the violations of privacy in both sound and complete. However the still there is scope of improvement in PRIGUARD method and limitations. One such limitation of PRIGUARD does not supporting the proactive violations of its commitments whenever its required to pro-vide the context dependent privacy management. In this paper we are presenting the Automated PRIGUARD (APRI-GUARD) which is based on existing PRIGUARD method. APRIGUARD method not only supports the functionality of existing PRIGUARD but also enabling the approach of proactively violates its commitments. This achieves more efficiency and security to end users privacy. The proposed approach will be used before taking a particular action for checking whether it will lead violation and hence it will results in its prevention before it happens. Antithesis, it will be utilized to do sporadic checks on the system to see if any violations have occurred.)

In this paper we are presenting the Automated PRIGUARD (APRI-GUARD) which is based on existing PRIGUARD method. APRIGUARD method not only supports the functionality of existing PRIGUARD but also enabling the approach of proactively violates its commitments. This achieves more efficiency and security to end users privacy. The proposed approach will be used before taking a particular action for checking whether it will lead violation and hence it will results in its prevention before it happens. Antithesis, it will be utilized to do sporadic checks on the system to see if any violations have occurred.)","PeriodicalId":6604,"journal":{"name":"2018 Second International Conference on Computing Methodologies and Communication (ICCMC)","volume":"82 1","pages":"945-949"},"PeriodicalIF":0.0,"publicationDate":"2018-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87046865","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}
