With the Internet penetration rate going higher, huge amount of log files are being generated, which contains hidden information having enormous business value. To unlock the hidden returns, log management system helps in making business decisions. Although, a lot of log management exist but they either fail to scale or are costly. Here efforts have been made to solve the shortcomings of prevailing log analyzer tools and this paper demonstrates the working of ELK ecosystem i.e. Elasticsearch, Logstash and Kibana clubbed together to efficiently analyze the log files and provide an interactive and easily understandable insights. Log management systems built on ELK stack are desired to analyze large log data sets while making the whole computation process easy to monitor through an interactive interface. Being from open source community ELK stack has many useful features for log analysis. Elasticsearch is used as Indexing, storage and retrieval engine. Logstash acts as a Log input slicer and dicer and output writer while Kibana performs Data visualization using dashboards. By implementing ELK ecosystem we have efficiently geo-identify the website users traffic using logs.
随着互联网普及率的提高,产生了大量的日志文件,这些日志文件中隐藏着具有巨大商业价值的信息。为了解开隐藏的回报,日志管理系统有助于制定业务决策。虽然存在很多日志管理,但它们要么无法扩展,要么成本高昂。本文努力解决当前流行的日志分析工具的缺点,并展示了ELK生态系统的工作,即Elasticsearch, Logstash和Kibana组合在一起,有效地分析日志文件,并提供交互式和易于理解的见解。建立在ELK堆栈上的日志管理系统,在分析大型日志数据集的同时,通过交互界面使整个计算过程易于监控。来自开源社区的ELK堆栈有许多有用的日志分析功能。Elasticsearch被用作索引、存储和检索引擎。Logstash充当日志输入切片器、切块器和输出写入器,而Kibana使用仪表板执行数据可视化。通过实现ELK生态系统,我们有效地利用日志对网站用户流量进行地理识别。

The foremost problem that arises in the Software Development Cycle is during the Requirements specification and analysis. Errors that are encountered during the first phase of the cycle migrate to other phases too which in turn results in the most costly process than the original specified process. The reason is that the specifications of software requirements are termed in the Nature Language Format. One can easily transform the requirements specified into computer model using UML. To minimize the errors that arise in the existing system, we have proposed a new technique that enhances the generation of UML models through Natural Language requirements, which can easily provide automatic assistance to the developers. The main aim of our paper is to focus on the production of Activity Diagram and Sequence Diagram through Natural Language Specifications. Standard POS tagger and parser analyze the input i.e., requirements in English language given by the users and extract phrases, activities, etc. from the text specifies. The technique is beneficial as it reduces the gap between informal natural language and the formal modeling language. The input is the requirements laid down by the users in English language. Some stages like pre-processing, part of speech (POs), tagging, parsing, phrase identification and designing of UML diagrams occur along with the input. The application and its framework is developed in Java and it is tested on by implementing on a few technical documents.
在软件开发周期中出现的最重要的问题是在需求规范和分析期间。在周期的第一阶段遇到的错误也会迁移到其他阶段,这反过来导致比原始指定流程成本最高的流程。原因是软件需求的规格说明是用自然语言格式命名的。使用UML可以很容易地将指定的需求转换为计算机模型。为了最小化现有系统中出现的错误,我们提出了一种新的技术,通过自然语言需求增强UML模型的生成,它可以很容易地为开发人员提供自动帮助。本文的主要目的是通过自然语言规范研究活动图和序列图的生成。标准的POS标注器和解析器分析输入,即用户给出的英语语言需求,并从文本指定中提取短语、活动等。该技术是有益的,因为它减少了非正式自然语言和正式建模语言之间的差距。输入是由用户用英语提出的要求。一些阶段,如预处理、词性、标记、解析、短语识别和UML图的设计,都伴随着输入而发生。该应用程序及其框架是用Java开发的,并通过在一些技术文档上实现对其进行了测试。

Green Cloud, a packet simulator focuses on maximising the system throughput with saving energy on different servers. Job Scheduling is one of the major issues in Green Cloud Computing. Some researches have been done on the preemptive scheduling on the Clouds as well as Green Clouds but lot more have to be done on Preemptive part of Priority Scheduling of the Green Clouds. To produce maximum throughput of Green Clouds the work has to be done by prioritizing the jobs on every cloud. In this paper we have proposed a new Preemptive Priority Based Job Scheduling Algorithm in Green Cloud Computing (PPJSGC). Our paper focuses on the preemptive part as well as it calculates the energy consumption for scheduling the jobs on the computing servers. The computing servers are allocated to processes based on the best fit as per their energy requirements and server frequency availability. This job is being performed by the DVFS Controller in our algorithm. The load management, low energy consumption, and maximizing the revenue is the key motive of our study.
Green Cloud是一个数据包模拟器,专注于通过在不同服务器上节省能源来最大化系统吞吐量。作业调度是绿色云计算的主要问题之一。在云和绿云上的抢占调度已经做了一些研究,但在绿云优先级调度的抢占部分还需要做更多的研究。为了产生绿云的最大吞吐量,必须在每个云上对作业进行优先级排序。本文提出了一种绿色云计算中基于抢占优先级的作业调度算法(PPJSGC)。本文重点研究了抢占部分,并计算了在计算服务器上调度作业的能耗。计算服务器根据其能量需求和服务器频率可用性的最佳匹配分配给进程。这个任务是由我们算法中的DVFS控制器执行的。负荷管理、低能耗、收益最大化是我们研究的主要动机。

Software metrics are developed and used by various software organizations for evaluating and assuring software code quality, operation and continuance. We differentiate software complexity metrics in accordance with the procedural and object oriented approach of programming languages. Software developers and maintainers need to read and understand source programs. The increase in size and complexity of software affects several quality attributes, especially understandability and maintability. In this paper we discuss various procedural and object oriented software metrics. We tried to calculate complexity of sample code by using different procedural metrics. The propose this simulation is to show that complexity for same code differs from metric to metric. The effectiveness of any metric is different for procedural and object oriented approach. So we proposed a hybrid approach to get accurate complexity value.
软件度量标准是由各种软件组织开发和使用的,用于评估和保证软件代码的质量、操作和持续性。我们根据编程语言的过程和面向对象的方法来区分软件复杂性度量。软件开发人员和维护人员需要阅读和理解源程序。软件规模和复杂性的增加影响了几个质量属性,特别是可理解性和可维护性。在本文中,我们讨论了各种过程和面向对象的软件度量。我们尝试通过使用不同的过程度量来计算示例代码的复杂性。提出这个模拟是为了显示相同代码的复杂度在不同的度量中是不同的。对于面向过程和面向对象的方法,任何度量的有效性都是不同的。因此,我们提出了一种混合方法来获得精确的复杂度值。

Age Simulation and Age Specific Human Computer Interaction (ASHCI) has a vital role in real life applications. Still automatic age estimation is a field which comprises of less research and is in developing state. The reason behind is that aging is an unique process which varies from person-to-person. The basic aim of this paper is to develop a user friendly system that estimates accurate age of an individual. In this paper age of an individual is estimated with the help of AGES pattern (Aging Pattern Subspace). The main aim is to generate aging pattern on which further enhancement is done applying PCA and computing minimum error rate. A good aging pattern can be generated with the help of proper projection in the subspace to get revised and appropriate face images. AGES has shown promising results when implemented and a very user friendly method.
年龄模拟和年龄特定人机交互(ASHCI)在现实生活中有着重要的应用。然而,年龄自动估计是一个研究较少、处于发展阶段的领域。背后的原因是衰老是一个独特的过程,因人而异。本文的基本目标是开发一个用户友好的系统来准确估计个人的年龄。本文利用年龄模式子空间(age pattern Subspace)来估计个体的年龄。主要目的是生成老化模式,在此基础上应用主成分分析进行进一步增强,并计算最小错误率。通过在子空间中进行适当的投影,生成良好的老化模式,从而得到修正后的、合适的人脸图像。AGES在实施过程中显示出良好的效果,并且是一种非常用户友好的方法。

The exponential growth of Digital media has made large number of videos available to us on social video sharing platforms. These videos are generally loosely tagged by users making video indexing and retrieval methods inefficient. A pressing problem has cropped up of categorizing theses videos. In this paper we present/propose an innovative method for classifying and tagging videos. This study initially deals with face recognition in videos and then automation of tagging them. This novel content based automatic tagging algorithm will dramatically reduce human effort and increase video searching efficiency.

The advancement of technology has led to an exceptional demand for high speed VLSI architectures having huge structures and high complexity. System partitioning provides an easy approach to recursively split the whole system into small sub-systems called blocks. With the enormous increase of system complexity in the past and further advancement of microelectronic system design, partitioning has become a central and sometimes critical design task. With the shrinking technology, interconnect dominates the chip performance and to reduce the number of interconnections between blocks is the biggest challenge for a designer. The 3D technology seems to significantly aid the reduction of wire length and also dealing with the issues like delay, power dissipation and signal integrity etc. In this work, an improved solution for layer assignment problem has been proposed utilizing the concept of adjacency matrix of a graph. It optimizes and reduces the complexity of already existing algorithm based on the concept of adjacency matrix of a graph. The final results prove the efficiency of the proposed method over existing works.
技术的进步导致了对具有巨大结构和高复杂性的高速VLSI架构的特殊需求。系统分区提供了一种简单的方法,将整个系统递归地划分为称为块的小子系统。随着过去系统复杂性的急剧增加和微电子系统设计的进一步发展,划分已经成为一个核心的,有时甚至是关键的设计任务。随着技术的不断缩小,互连性主导着芯片的性能,减少模块之间的互连数量是设计人员面临的最大挑战。3D技术似乎大大有助于缩短电线长度,同时也解决了延迟、功耗和信号完整性等问题。本文利用图的邻接矩阵的概念,提出了一种改进的层分配问题的解决方案。它基于图的邻接矩阵的概念,对已有算法进行了优化,降低了算法的复杂度。最后的结果证明了该方法的有效性。
