Landslide is a natural hazard, which badly affects people's safety and property. Continuous monitoring of such a disaster may lead to reducing of losses of human lives. With this aim, in this paper, we have proposed a surveillance system for real time landslide monitoring using computer vision algorithms. Here we have used a video camera to acquire live view of landslide site and a small computer board ‘raspberry Pi’ to run the algorithm we will introduce here. When landslide is detected SMS text messages are transmitted using a GSM modem. Due to video camera and Raspberry Pi, this method is inexpensive yet efficient and also requires low power, therefore this method can be used in any region. We have used median filtering to remove noise present in the detection algorithm. Here we have also proposed a new implementation method for median filtering using a linked list and parallel processing which is very time efficient.
滑坡是一种严重影响人民生命财产安全的自然灾害。对这种灾害的持续监测可能会减少人类生命的损失。为此,本文提出了一种基于计算机视觉算法的滑坡实时监测系统。在这里,我们使用摄像机获取滑坡现场的实时视图,并使用小型计算机板“树莓派”来运行我们将在这里介绍的算法。当检测到山体滑坡时,通过GSM调制解调器发送短信。由于有摄像机和树莓派,这种方法既便宜又高效,而且功耗低,因此这种方法可以在任何地区使用。我们使用中值滤波来去除检测算法中存在的噪声。本文还提出了一种采用链表并行处理的中值滤波新实现方法,该方法具有很高的时间效率。

In recent technology of digital signal processing applications, we have number of modulation and demodulation techniques. In this domain multiplexing technique is having greatest importance as it has a transmission and reception part with secure systems for communication. Thus orthogonal frequency division multiplexing (OFDM) is superior to other multiplexing techniques, which has multiple carriers with very much robust frequency selective distorted channels. OFDM will have a number of modules such as serial to parallel converter, modulator, IFFT, FFT, demodulator and so on. The Proposed work will concentrate on arithmetic operations in OFDM with re-modified technique using large integer values such as addition, and multiplications. This large integer based arithmetic operation technique were designed using Schönhage-Strassen algorithm (SSA). Thus the proposed method will focus on this SSA algorithm based arithmetic operations with Number Theoretic Transform (NTT) and Inverse Number Theoretic transform (INTT) method. Proposed method of OFDM will replace FFT-IFFT to NTT-INTT method and this application is developed in Verilog HDL and synthesized in Xilinx vivado 15.4. It proved better results in terms of area and delay when compared with conventional design.
在最近的数字信号处理应用技术中,我们有许多调制和解调技术。在这一领域中,多路复用技术具有重要的意义,因为它具有传输和接收部分以及安全的通信系统。因此,正交频分复用技术(OFDM)优于其他复用技术,它具有多载波和非常鲁棒的频率选择性失真信道。OFDM将有串并转换器、调制器、IFFT、FFT、解调器等多个模块。建议的工作将集中于OFDM中的算术运算,使用大整数值(如加法和乘法)进行再修改技术。采用Schönhage-Strassen算法(SSA)设计了基于大整数的算术运算技术。因此,本文提出的方法将重点研究基于SSA算法的基于数论变换(NTT)和数论逆变换(INTT)方法的算术运算。提出的OFDM方法将FFT-IFFT替换为NTT-INTT方法,该应用在Verilog HDL中开发,在Xilinx vivado 15.4中合成。与传统设计相比,在面积和时延方面取得了更好的效果。

Nowadays most of the data transmission is done through digital communication and hence security and efficient data transmission is always a desirable property for any data communication. At present, Advance encryption standard (AES) is most widely used cryptographic technique. This AES uses static s box for encryption and decryption which remains constant irrespective of the key. Numerous analysts have experimented and revealed that there are some weak points [1] in the static s-box as it is static and known to all. Therefore, in our proposed algorithm we modify AES such that it uses dynamic sbox which is key dependent and compare the avalanche effect of basic AES with our proposed algorithm.
目前,大多数数据传输都是通过数字通信完成的,因此安全高效的数据传输一直是任何数据通信的理想属性。高级加密标准AES (advanced encryption standard)是目前应用最广泛的加密技术。该AES使用静态密码盒进行加密和解密,无论密钥是什么,它都保持不变。许多分析人员进行了实验并揭示了静态s盒中存在一些弱点[1],因为它是静态的并且众所周知。因此,在我们提出的算法中,我们修改AES,使其使用依赖于密钥的动态sbox,并将基本AES的雪崩效应与我们提出的算法进行比较。

In this paper, Structural optimization based microstrip bandpass filter design is discussed. Conventional optimization mainly focuses on the dimensional optimization of the filter. Here, the focus is to design a bandpass filter using rectangular patch-based resonator. The obtained result is then optimized using Genetic Algorithm which is part of Evolutionary algorithm. In order to obtain an optimized result, we define a fitness function in terms of $S_{11}$ (dB) and $S_{21}$ (dB) parameters. The final design of the filter will possess maximum transmission co-efficient and minimum reflection co-efficient.

Moving data and computation to the cloud is a promising technology in recent years. As the device density increases in the connected world, proper storage in the traditional cloud without security threats is a cumbersome task. Modification and leakage of data is the major threat in adopting cloud computing. Intelligent technologies are needed to safeguard against cyber-attacks. Fog paradigm enables users for data storage, management and network functions closer to them. Fog server introduced as a middle layer between user devices and the cloud to provide more security for uploaded data. It collects and transfers the encrypted data from the user, and apply reed Solomon code for error detection and MD5 hashing for malicious message detection to ensure more security and integrity. This data will be stored in different cloud servers and respective user's fog devices. Thus the combination of cloud with fog computing will ensure integrity, availability and confidentiality of users data.

Network virtualization encourages the assured resource management in which particular Virtual Network is allowed to be mapped on common or shared physical infrastructure. This mechanism termed as a problem of Virtual Network Embedding(VNE). It is considered to be NP-hard, and various heuristic, meta-heuristic, and exact solutions are proposed already in the past literature. In this paper study on different categories of VNE is presented. It also discusses multiple different approaches used to solve VNE among various networking environment like wireless networks, optical networks, cloud infrastructure, etc. The paper elaborates taxonomy of VNE optimization methods, considering dynamic or static, centralized or distributed and concise or redundant scenarios. Also focusses on a discussion of crucial algorithmic aspects and possible research directions.

QoS Evaluation of VANET Routing Protocol VANET路由协议的QoS评价
Pub Date : 2019-07-01 DOI: 10.1109/ICCES45898.2019.9002115

In today's smart revolutionary era, Intelligent Transportation System (ITS) is a buzzword that plays a vital role. Vehicular ad-hoc network (VANET) techniques help ITS for improving efficiency as well as road safety services to vehicles and drivers. The vehicle acts as a node in the special ad-hoc network. Communication in the VANET is accomplished through IEEE802.11p i.e. Dedicated Short Range Communication (DSRC) and Wireless Access Vehicular Environment (WAVE). The ways of communication in the VANET are within vehicles (V2V) and vehicle-to-road (V2R). Routing is a foremost issue in the VANET environment due to the dynamic variation of topology, the restricted movement pattern of the vehicle, unstable links and complex city environments. Implementation of the VANET environment is a difficult task in a real environment. The objective of the paper is to simulate topological routing protocols to evaluate QoS. The simulation uses ManhattanGrid mobility to reflect the realistic vehicular environment. The simulation is conducted in various test environments with the variation in the vehicular density and speed of the vehicle. The influence of both factors on the QoS parameter is evaluated with Packet Delivery Ratio, Throughput, Avg. E2ED and Normalized Routing Overhead. AODV produces better PDR, Throughput and less NRL. OLSR produces less Avg. E2ED with respect to other protocols.
在当今智能革命时代,智能交通系统(ITS)是一个至关重要的流行语。车辆特设网络(VANET)技术帮助智能交通系统提高效率,并为车辆和驾驶员提供道路安全服务。车辆在特殊的自组织网络中充当节点。VANET中的通信是通过IEEE802.11p即专用短距离通信(DSRC)和无线接入车载环境(WAVE)完成的。VANET的通信方式分为车内通信(V2V)和车对路通信(V2R)。由于拓扑结构的动态变化、车辆运动模式的有限性、链路的不稳定性以及复杂的城市环境,路由问题成为VANET环境中的首要问题。在真实环境中实现VANET环境是一项艰巨的任务。本文的目的是模拟拓扑路由协议来评估QoS。模拟使用曼哈顿电网的机动性来反映真实的车辆环境。仿真是在不同的试验环境下,根据车辆密度和行驶速度的变化进行的。这两个因素对QoS参数的影响通过分组投递率、吞吐量、平均E2ED和归一化路由开销来评估。AODV产生更好的PDR,吞吐量和更少的NRL。与其他协议相比,OLSR产生的平均E2ED较少。

The paper focuses on a Simulink based model and design of the different control mechanisms of a DC motor powered via fuel cell. At first, fuel cell is used as the prime power source of the DC motor and a differential controller is used to achieve a uniform output. Then, the differential controller is replaced with Proportional Integral (PI) controller, Proportional Integral Differential (PID) controller and Fuzzy Logic Controller (FLC) subsequently to compare and demonstrate the variations that occur in the different characteristic curves with the change in various parameters. If Photovoltaic cell is used instead of fuel cell, the output operation of the DC motor may vary. So, in addition, a comparative performance analysis of both methods of power with regards to DC motor control is also presented.
本文重点研究了基于Simulink的燃料电池直流电机的控制模型和不同控制机构的设计。首先采用燃料电池作为直流电机的主电源,并采用差动控制器实现均匀输出。然后,将微分控制器替换为比例积分(PI)控制器、比例积分微分(PID)控制器和模糊逻辑控制器(FLC),比较和演示不同特性曲线随各参数变化的变化情况。如果使用光伏电池代替燃料电池,直流电机的输出操作可能会发生变化。此外,本文还对两种功率方法在直流电机控制方面的性能进行了比较分析。

At first, fuel cell is used as the prime power source of the DC motor and a differential controller is used to achieve a uniform output. Then, the differential controller is replaced with Proportional Integral (PI) controller, Proportional Integral Differential (PID) controller and Fuzzy Logic Controller (FLC) subsequently to compare and demonstrate the variations that occur in the different characteristic curves with the change in various parameters. If Photovoltaic cell is used instead of fuel cell, the output operation of the DC motor may vary. So, in addition, a comparative performance analysis of both methods of power with regards to DC motor control is also presented.","PeriodicalId":348347,"journal":{"name":"2019 International Conference on Communication and Electronics Systems (ICCES)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121296203","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}

Machine Translation is the programmed interpretation of one natural language to another natural language. Human languages can be processed by computers via grammars/rules or via statistics/data. There are many machine translation techniques which are either Rule-based or Knowledge-based. In this paper we will discuss the Statistical Machine Translation (SMT) techniques. The Statistical Machine Translation makes use of statistics or data to find the translation of a given source text. In word primarily based SMT, the simple unit of translation is a word. As a consequence words in an input sentence are translated phrase by phrase individually and these words are than sooner or later organized in a particular way to get the target sentence. The paper discusses numerous fashions for the word based Statistical Machine translation. The paper is written with reference to Kashmiri Language, as not much work has been done in this regard.
机器翻译是一种自然语言到另一种自然语言的程序化解释。计算机可以通过语法/规则或统计/数据来处理人类语言。有许多基于规则或基于知识的机器翻译技术。本文将讨论统计机器翻译(SMT)技术。统计机器翻译利用统计数据或数据来查找给定源文本的翻译。在基于词的SMT中,翻译的简单单位是一个词。因此,输入句子中的单词是一个短语一个短语地单独翻译的,这些单词迟早会以特定的方式组织起来,以得到目标句子。本文讨论了基于词的统计机器翻译的几种方法。该文件是参照克什米尔语编写的,因为在这方面做的工作不多。
