A. Sharma, M. Trivedi
MANET is a collection of computational devices that creates random topology for communication. The beauty of MANET is that it not required any central controller or base station. The devices used in MANET may be fixed or mobile. MANET is only a network in which devices worked as a host as well as router. The routing protocol used in mobile ad hoc network is broadly classified in three category-proactive, reactive and hybrid routing protocol. In this thesis work performance of AODV, AODVDR and ZRP is compared in the presence of different number of connection, different pause time and different number of communicating devices. In this work, network simulator tool NS2.35 is used for simulation. Simulation result shows the AODVDR is perform better than AODV and ZRP routing protocol.
MANET是为通信创建随机拓扑的计算设备的集合。MANET的优点在于它不需要任何中央控制器或基站。在MANET中使用的设备可以是固定的,也可以是移动的。MANET只是一种网络,在这种网络中,设备既可以作为主机又可以作为路由器。移动自组织网络中使用的路由协议大致分为主动路由协议、被动路由协议和混合路由协议。本文比较了AODV、AODVDR和ZRP在不同连接数、不同暂停时间和不同通信设备数情况下的工作性能。在本工作中,使用网络模拟器工具NS2.35进行仿真。仿真结果表明,AODVDR的性能优于AODV和ZRP路由协议。

Tackling Roadblocks to Achieve Optimum DDR Performance 解决障碍,实现最佳的DDR性能
Amit Pal, A. Sinha, Abhinav Gaur
As the processor speed is increasing day by day with the advancement in technology, memory vendors are forced to come-up with newer solutions which could match the processor speed without impacting the overall system efficiency. That's why industry has moved from SDRAM era to DDR4 era where memory is running at a speed more than 3GHz. DDR memory devices have been optimized for maximum speed and minimum power possible by the manufacturers, but are these enough to get the best out of any SOC? There are several parameters present at memory controller and SOC level which could impact the performance in a greater way and if they are not taken care appropriately, it could result into an inefficient system. Without optimizing those parameters, it is impossible to get the best outcome from the memory it is designed for. This paper throws light on those parameters and shows some result that how significantly DDR performance improves by optimizing those parameters. This paper also talks about system level scenarios where graphic controller is accessing DDR3 memory and how its read/write performance was increased within given cycles. It also describes different profilers used in hardware to measure the performance in an efficient manner.
随着技术的进步,处理器的速度日益提高,内存供应商被迫提出新的解决方案,以匹配处理器的速度,而不会影响整个系统的效率。这就是为什么行业已经从SDRAM时代转移到DDR4时代,内存的运行速度超过3GHz。DDR存储设备已被制造商优化为最大速度和最低功耗,但这些是否足以从任何SOC中获得最佳效果?在内存控制器和SOC级别上存在几个参数,这些参数可能会以更大的方式影响性能,如果不适当地加以注意,可能会导致系统效率低下。如果不优化这些参数,就不可能从它所设计的内存中获得最佳结果。本文对这些参数进行了分析,并给出了通过优化这些参数可以显著提高DDR性能的一些结果。本文还讨论了图形控制器访问DDR3内存的系统级场景,以及如何在给定周期内提高其读/写性能。它还描述了在硬件中使用的不同分析器,以有效的方式测量性能。

Priti Singh, A. Chakraborty, Ashok Yadav
In recent years antennas operating on millimeter-wave frequencies have generated a considerable demand. The various unique applications of millimeter wave antennas along with the availability of the bandwidth makes them a very promising area which is yet to be explored. This paper is for designing of conventional antennas which can work for millimeter wave frequencies. This work includes mathematical analysis and designing of Horn and Yagi-uda antennas for mm-wave and simulation of basic parameters using HFSS. A rectangular shaped slot is incorporated into patch, and antenna structure is used as a patch with coplanar waveguide (CPW) as a feeding structure. A brief mathematical theory of both antennas, software introduction, design, applications and variations between calculated and observed values will be discussed along the result of our design. Our results and analysis show that the antennas are showing significant gain, so they can be applied for the applications we are aiming for.

Faucet Add-On Water Supply Management System Using Smart Sensors 使用智能传感器的水龙头附加供水管理系统
Prachi Dutta, Uzval Sai Gopinadha Varma Dontiboyina
Due to growing demands of water in the upcoming years and with many countries severely impacted by water crises today, we would need a more efficient system than traditional techniques of domestic water management. This paper aims at developing an efficient and cost effective method of placing an upper limit on the amount of water used daily. Our prototype is a faucet device which has two modes of operation: running mode and filling mode. User is pre-alarmed when more than optimum water amount is being dispensed. In order to do this, we have embedded an algorithm that integrates functions such as data acquisition and data management in a microcontroller that dynamically computes and compares the amount of water being dispensed through the flow sensor, with ideally required water amount for the two modes of operation. The proposed design is a strategy which will also help the user to keep a check on the amount of water leaking from the faucet, promoting smart planning for healthy and sustainable water management. This novel monitoring approach is inexpensive which also saves affluent quantity of water.

Selection of Optimal Services Working on SCM Strategies Using Fuzzy Decision Making Methods 基于模糊决策方法的供应链管理最优服务选择
Aarti M. Karande, D. Kalbande
Supply Chain Management based organizations need to focus on development of strategies based on the services provided by them to stakeholders. To improve supplier chain value, optimal services need to be selected which may become agile based on the organizational factors. Agility can be differentiated at different levels of execution in SCM organization. Agility and leanness philosophies based on the range of products and services are provided by the organization. This paper focuses on the agility for services provided by SCM based organization. Since in every system there is fuzziness in its structure and function. The functional fuzziness can be easily reduced and compared to structural fuzziness. In this paper different methods based on fuzzy decision methods are compared for strategy development. Each service provided by organization is mapped with SCM strategies. From this set of services, optimal service is selected. This paper explains a case study of an organization working on SCM strategies. To find optimal service, different decision methods like Saaty's method, minimization of maximal regret method, AHP method, ranking method, and fuzzy average weighted method are compared to measure relativity of fuzziness in multiple objective frameworks by structuring the system hierarchically. This paper also shows advantages and disadvantage of these method as well as mathematical operation for selection of optimal services based on SCM strategies.
基于供应链管理的组织需要将重点放在基于他们向利益相关者提供的服务的战略开发上。为了提高供应链价值,需要根据组织因素选择最优的服务,使其变得敏捷。敏捷性可以在SCM组织的不同执行级别上进行区分。组织提供基于产品和服务范围的敏捷和精益理念。本文主要研究基于SCM的组织所提供的服务的敏捷性。因为在每个系统中,其结构和功能都是模糊的。功能模糊可以很容易地减少,并与结构模糊进行比较。本文比较了基于模糊决策方法的不同策略制定方法。组织提供的每个服务都映射到SCM策略中。从这组服务中选择最优服务。这篇论文解释了一个从事SCM战略的组织的案例研究。为了寻找最优服务,比较了Saaty法、最大遗憾最小化法、AHP法、排序法和模糊平均加权法等不同的决策方法,通过分层构建系统来度量多目标框架中模糊性的相关性。本文还分析了这些方法的优缺点,并给出了基于供应链管理策略的最优服务选择的数学运算。

MapReduce Model of Improved K-Means Clustering Algorithm Using Hadoop MapReduce 基于Hadoop MapReduce改进K-Means聚类算法的MapReduce模型
N. Akthar, Mohd Vasim Ahamad, Shahbaaz Ahmad
In today's digital world scenario, digital data is coming in and going out faster than ever before. This data is of no use until we extract some useful content from it. But, it is impractical and inefficient to use traditional database management techniques on big data. That's why, big data technologies like Hadoop comes to existence. Hadoop is an open source framework, which can be used to process the huge amount of data in parallel. To extract useful information, data mining techniques can be used. Among many techniques of data mining, clustering is most popular technique. Clustering bind together the similar data in same group, whereas, dissimilar data is scattered in different groups. K Means clustering algorithm is one of the clustering technique. Traditional K Means clustering tries to assign n data objects to k clusters starting with random initial centers. Experiments show that data mining results are inefficient and unstable, if we use random initial centers. In this paper, we have modified traditional K Means clustering algorithm by using improved initial centers. We have proposed various methods to calculate the initial centers and compared their results.
在当今的数字世界中,数字数据的输入和输出速度比以往任何时候都要快。除非我们从中提取出一些有用的内容,否则这些数据是没有用的。但是,在大数据上使用传统的数据库管理技术是不切实际的,效率低下的。这就是像Hadoop这样的大数据技术出现的原因。Hadoop是一个开源框架,可以用来并行处理海量数据。为了提取有用的信息,可以使用数据挖掘技术。在众多的数据挖掘技术中,聚类是最受欢迎的技术。聚类将相似的数据聚在一起,而不相似的数据分散在不同的组中。K均值聚类算法是聚类技术的一种。传统的K均值聚类试图将n个数据对象分配到K个随机初始中心的聚类中。实验表明,如果使用随机初始中心,数据挖掘结果是低效且不稳定的。本文利用改进的初始中心对传统的K均值聚类算法进行了改进。我们提出了各种计算初始中心的方法,并比较了它们的结果。

Performance Analysis of the Competitive Learning Algorithms on Gaussian Data in Automatic Cluster Selection 高斯数据竞争学习算法在自动聚类选择中的性能分析
Harsh Khatter, V. Aggarwal, A. Ahlawat
A clustering problem occurs when an object needs to be assigned into a predefined group or class based on a number of observed attributes related to that object. The existing Competitive Learning (CL) algorithm and its variants (Frequency Sensitive Competitive Learning (FSCL), Rival Penalized Competitive Learning (RPCL), and Rival Penalized Controlled Competitive Learning (RPCCL)) have provided an appealing way to perform data clustering without knowing the exact number of clusters prior to clustering. This paper studies and analyzes the performance of these algorithms. The experimental results have been analyzed on the 2-D Gaussian data with the learning rate parameter kept same for all algorithms. The result showed that if number of output clusters is chosen equal to the number of clusters present in the input data then the performance for all the algorithms remains almost equal but when this number is chosen larger than the clusters present, then the RPCCL outperforms the other algorithms. Thus RPCCL gives the best performance in automatic cluster selection and we can use this feature of RPCCL algorithm in various useful applications like cluster analysis, curve detection, image segmentation, medical data analysis etc.
当需要根据观察到的与对象相关的许多属性将对象分配到预定义的组或类中时,就会出现聚类问题。现有的竞争学习(CL)算法及其变体(频率敏感竞争学习(FSCL)、对手惩罚竞争学习(RPCL)和对手惩罚控制竞争学习(RPCCL))提供了一种吸引人的方法来执行数据聚类,而在聚类之前不知道确切的聚类数量。本文对这些算法的性能进行了研究和分析。在所有算法的学习率参数相同的情况下,在二维高斯数据上对实验结果进行了分析。结果表明,如果选择输出簇的数量等于输入数据中存在的簇的数量,那么所有算法的性能几乎保持相等,但是当选择的数量大于存在的簇时,则RPCCL优于其他算法。因此,RPCCL算法在自动聚类选择方面具有最好的性能,我们可以在聚类分析、曲线检测、图像分割、医疗数据分析等各种有用的应用中使用RPCCL算法的这一特性。

Coordinated Fault Ride through Strategy for SCIG Based WECS 基于SCIG的wcs协调故障穿越策略
H. Ahuja, S. Sharma, G. Singh, Arvind Sharma, Arika Singh
Wind technology is one of the fastest developing renewable technologies. Squirrel cage induction generator (SCIG) with back to back fully rated converter used for wind energy conversion systems (WECS) is a meritorious option among its class. SCIG's offer advantages of being robust, suitable for any harsh environment, cheaply available and unsophisticated than the other types available. To enable increased share of wind energy in the grid without compromising power system stability, the generator ought to stay connected and continue to feed the grid even in case of disturbances such as voltage sag. This paper presents a coordinated control scheme to address the fault ride through of SCIG based WECS. A WECS based on SCIG having back to back connected voltage source converters involving Rotor flux oriented vector controlled drive at machine side and hysteresis current controlled inverter for grid interface has been simulated in MATLAB/SIMULINK. Abnormal rise in dc link voltage during symmetrical faults is controlled by de-loading control while positive-negative sequence control is used for real and reactive power control during symmetrical and unsymmetrical faults. During this work, coordinated performance of all the above stated control strategies during most severe symmetrical (LLL) and most frequently occurring unsymmetrical (LG) fault has been examined.
风能技术是发展最快的可再生能源技术之一。用于风能转换系统(WECS)的鼠笼式感应发电机(SCIG)与背靠背全额定变流器是同类产品中值得信赖的选择。SCIG的优点是坚固耐用,适用于任何恶劣环境,比其他类型便宜且简单。为了在不影响电力系统稳定性的情况下增加风能在电网中的份额,发电机应该保持连接,即使在电压下降等干扰的情况下也要继续向电网供电。本文提出了一种协调控制方案来解决基于SCIG的wcs的故障穿越问题。在MATLAB/SIMULINK中对一种基于SCIG的电压源变换器背靠背连接的wcs进行了仿真,其中电机侧转子磁链定向矢量控制驱动和电网接口的磁滞电流控制逆变器。对称故障时直流链路电压异常升高的控制采用卸载控制,对称和非对称故障时实功和无功控制采用正负序控制。在这项工作中,研究了所有上述控制策略在最严重的对称(LLL)和最频繁发生的不对称(LG)故障时的协调性能。

Implementation & BER Analysis of 2×2 MIMO Using USRP 2920- Universal Software Radio Peripheral 利用USRP 2920通用软件无线电外设实现2×2 MIMO及误码率分析
G. Soni, G. Kaur, V. Banga
With the advent of MIMO, more utilization of scarce spectrum could be achieved by using lesser power consumption. In some situations, results of practical implementations are lower as compared to simulation results. The implementation of dual antenna array architectures to create multiple-input multiple-output (MIMO) configurations has attracted considerable interest in wireless communication technology to improve the overall system performance. This article provides an experimental analysis to these MIMO communication systems and explains how such capacity gains can be achieved using this technology. This paper provides a detailed performance analysis for open loop (OL) MIMO schemes for the mobile broadband radio access technology like 3GPP. In this work, practical results are analyzed using USRPs 2920. The coding technique used in the work is space time block code that creates capacity gain and helps in improvement of robustness of the link. The results presented in this paper are based on experimental MIMO set-up(2*2) using USRP 2920 (Universal Software Radio Peripheral). The antennas used for experimental investigation is 7 inch vertical tri-band antenna.
随着MIMO技术的出现,可以以更低的功耗实现对稀缺频谱的更多利用。在某些情况下,实际实现的结果比仿真结果要低。实现双天线阵列架构以创建多输入多输出(MIMO)配置已经引起了人们对无线通信技术的极大兴趣,以提高整体系统性能。本文提供了对这些MIMO通信系统的实验分析,并解释了如何使用该技术实现这种容量增益。本文对3GPP等移动宽带无线接入技术的开环MIMO方案进行了详细的性能分析。在这项工作中,使用usrp 2920对实际结果进行了分析。在工作中使用的编码技术是空时分组编码,产生容量增益,有助于提高链路的鲁棒性。本文给出的结果是基于使用USRP 2920(通用软件无线电外设)的实验性MIMO设置(2*2)。实验研究使用的天线为7英寸垂直三波段天线。
