Global software development is increasingly used in organizations where specialized skills are required to address specialized software development and support. The Global software development industry is such business that has had a huge impact over the last several years, demanding expert resources and their timely availability whenever and wherever needed. This dependence on software engineering has led to the transformation of the way the softwares are being developed today. Project team members from different geographical locations and cultures are involved in software development and getting many benefits include cost advantage, time, risk, productivity and 24/7 development. Communication and collaboration are the key technologies used in Global software development. These tools have their inherent problems and gray areas on which further research is required. These technologies must ensure the availability of sufficient resources, Project management needs to monitor project progress and status reports, planned milestones that must be understood and agreed among all team members and a refined high-performance process of Global Software development without unnecessary project activities that creates delays in the project. In this paper several communication barriers have been addressed that lead to project failure. The need to use faster, cheaper and cost effective means of communication tools has exerted a lot of pressure on software professionals to cater to the demand of the global world.
全球软件开发越来越多地用于需要专门技能来处理专门软件开发和支持的组织中。全球软件开发行业是这样的业务,在过去几年中产生了巨大的影响,要求专家资源和他们的及时可用性,无论何时何地都需要。这种对软件工程的依赖导致了今天软件开发方式的转变。来自不同地理位置和文化的项目团队成员参与到软件开发中,并获得许多好处,包括成本优势、时间、风险、生产力和24/7开发。通信和协作是全球软件开发中使用的关键技术。这些工具有其固有的问题和需要进一步研究的灰色地带。这些技术必须确保足够资源的可用性,项目管理需要监控项目进度和状态报告,所有团队成员必须理解并同意的计划里程碑,以及在没有不必要的项目活动的情况下,在项目中创建延迟的Global Software开发的精细高性能过程。本文讨论了导致项目失败的几个沟通障碍。使用更快、更便宜、更经济的通信工具的需求给软件专业人员施加了很大的压力,以满足全球的需求。

M. R. Belgaum, S. Soomro, Z. Alansari, Shahrulniza Musa, M. Alam, M. M. Su’ud
In Cloud computing environment the resources are managed dynamically based on the need and demand for resources for a particular task. With a lot of challenges to be addressed our concern is Load balancing where load balancing is done for optimal usage of resources and reduces the cost associated with it as we use pay-as-you-go policy. The task scheduling is done by the cloud service provider using preemption and non-preemption based on the requirements in a virtualized scenario which has been focused here. In this paper, various task scheduling algorithms are studied to present the dynamic allocation of resources under each category and the ways each of this scheduling algorithm adapts to handle the load and have high-performance computing.
在云计算环境中,资源是根据特定任务对资源的需求动态管理的。有很多挑战需要解决,我们关注的是负载平衡,其中负载平衡是为了实现资源的最佳使用,并在我们使用随用随付策略时降低与之相关的成本。任务调度是由云服务提供商根据虚拟化场景中的需求,使用抢占和非抢占来完成的。本文研究了各种任务调度算法,给出了各种任务调度算法在每个类别下资源的动态分配,以及每种调度算法处理负载和高性能计算的方法。

Improving network coding throughput in multi-hop networks through DCF adoption in 802.11 通过在802.11中采用DCF提高多跳网络中的网络编码吞吐量
Khaled D. Alferaidi, R. Piechocki
Wireless Multi-Hop networks often rely on the use of IEEE 802.11 technology, Regardless of the robustness of IEEE 802.11 Distributed Coordination Function (DCF) is not optimal in various network scenarios. In this study and other have experienced the inefficacy's of DCF when Network Coding is applied, therefore the room of improvement is needed to consider Network Coding technique. DCF is fairer to nodes than the process of Network Coding. Since the rely nodes in multi-Hop scenario have urgent requirements to gain more access and regulated access, which accommodate the network Coding process. We propose enhanced algorithm to DCF mechanism on MAC layer that favouring Network Coding, and guarantee to give more access to medium and better share of medium for relay nodes between bidirectional traffic flows in saturated network traffic scenario.
无线多跳网络通常依赖于IEEE 802.11技术的使用,尽管IEEE 802.11的分布式协调功能(DCF)具有鲁棒性,但在各种网络场景下都不是最优的。本研究和其他研究都经历了DCF在网络编码应用时的无效,因此需要考虑网络编码技术的改进空间。DCF比网络编码过程对节点更公平。由于多跳场景下的依赖节点迫切需要获得更多的访问和规范的访问,以适应网络编码过程。对MAC层的DCF机制提出了有利于网络编码的改进算法,保证在网络流量饱和的情况下,双向流量之间的中继节点有更多的介质访问和更好的介质共享。

Pichcha Bunvorn, A. Sopadang
Nowadays, information technology plays important roles in business, as it improves efficiency and effect trade advantages. This study implemented an information technology system that allowed Thai farmers to sell rice via social media and a website or E-commerce directly. Using the existing information network to form a market could save time and add values in logistics and supply chain, as well as improving service quality. A group of volunteered farmers in Chiang Mai and Chiang Rai provinces participated in the study by using the implemented website, thus allowing it was evaluated. The study tracked the sale statistics and surveyed users after three months of implementation. It was determined that the system added value to rice product by approximately 25 percent and increased sales by 20 percent. The system also provided useful information to sellers, allowing them to adapt to market changes.

Data processing in Hive vs. SQL server: A comparative analysis in the query performance Hive和SQL server的数据处理:查询性能对比分析
Nadeem Ahmed, Shakil Ahamed, Jahir Ibna Rafiq, Sifatur Rahim
Data processing means manipulating the input raw data using application program to get the desired output. The main target behind data processing is to convert unusable data into a usable form. Relational database management system (RDBMS) is playing main role for data processing in most of the organizations. MySQL, SQL Server, Oracle, SQLite are some of the well-known database management systems. Moving forward big data technology is becoming more admired towards many organizations as nature and size of data sets grow rapidly. Big data is particularly apt for extreme large volume where conventional data processing application is inadequate to deal. Generally, large organizations use big data technology for processing large volume of data. However, this paper targets the audience of Small Enterprises (SE) where the database size is relatively small and is not distributed over multiple servers. The attempted study examines the query execution time between traditional data warehouse, grounded on the SQLite, SQL Server and a parallel data warehouse grounded on the Hive built on the top of Hadoop so that SE can decide which system performs better in terms of the time of data processing. The study finds that it is better to use traditional database systems if SE does not have a plan in near future to work with vast amount of data i.e. the data set fits on a single computer.
数据处理是指使用应用程序对输入的原始数据进行操作,以获得所需的输出。数据处理背后的主要目标是将不可用的数据转换成可用的形式。关系数据库管理系统(RDBMS)在大多数组织中起着数据处理的主要作用。MySQL, SQL Server, Oracle, SQLite是一些著名的数据库管理系统。随着数据集的性质和规模的迅速增长,大数据技术越来越受到许多组织的青睐。大数据特别适合于传统数据处理方法无法处理的超大数据量。通常,大型组织使用大数据技术来处理大量数据。然而,本文的目标受众是小型企业(SE),其中数据库大小相对较小,并且没有分布在多个服务器上。该尝试研究考察了基于SQLite、SQL Server的传统数据仓库与基于Hadoop之上的Hive的并行数据仓库之间的查询执行时间,以便SE可以确定哪个系统在数据处理时间方面表现更好。研究发现,如果SE在不久的将来没有计划处理大量数据(即数据集适合在一台计算机上),则最好使用传统数据库系统。

Simulation and analysis of magnetic field strength with magneto-resistive sensor: A future application 磁阻传感器磁场强度模拟与分析:未来应用
Sangharatna M. Ramteke, H. Chelladurai, K. Pandian
The optimum orientation of four bar magnets to give an effective magnetic field strength with magneto-resistive (MR) sensor is proposed in this paper. The bar magnets having the same magnetic field strength of 4.51 kA/m are used and placed at a nominal distance from the MR sensor to get the maximum magnetic field strength and sensor voltage. The magnetic orientation and it's field strength is simulated and analyzed through Comsol Software and validated with the laboratory experimental results. The experimental result shows that the SSNN orientation at a distance of 0.5 cm from MR sensor comparatively gives higher magnetic field strength and sensor output voltage.

The wearable textile-based microstrip patch antenna preliminary design and development 基于可穿戴纺织品的微带贴片天线的初步设计与开发
E. N. F. S. Engku Embong, K. N. A. Rani, H. A. Rahim
This paper presents a preliminary development of a wearable textile microstrip patch antenna operating for wireless body area network (WBAN) at the center frequency, fc of 2.40 GHz. Textile materials are suitable to be designed as wearable antenna substrates due to their low dielectric constant or relative permittivity characteristics. Precisely, in this project, jeans fabric or denim with the relative permittivity, εr = 1.70 and thickness of 1.00 mm is chosen as a substrate attached to SheildIt Super as a conductive material with the thickness of 0.17 mm and conductivity of 6.67 × 105 S/m, respectively. In the first stage, a microstrip patch antenna layout with an edge feeding technique is designed and simulated by using Keysight Advanced Design System (ADS) software. In the second stage, a wearable textile microstrip patch antenna is fabricated, integrated, and hidden inside clothing, properly. Simulation and fabrication measurement results show that the designed antenna characteristics are suitable for an industrial, scientific, and medical radio (ISM) band, which is at the fc = 2.40 GHz. Moreover, relative permittivity, εr and thickness, h of the developed textile-based substrate affect significantly a wearable microstrip patch antenna radiation performance.
本文初步研制了一种可穿戴织物微带贴片天线,工作在中心频率为2.40 GHz的无线体域网(WBAN)。纺织材料由于其低介电常数或相对介电常数特性而适合设计为可穿戴的天线基板。具体而言,本项目选择相对介电常数εr = 1.70,厚度为1.00 mm的牛仔裤面料或牛仔布作为基材,附着在SheildIt Super上,作为导电材料,厚度为0.17 mm,电导率为6.67 × 105 S/m。在第一阶段,采用是德科技高级设计系统(ADS)软件,设计并仿真了一种边缘馈电技术的微带贴片天线布局。在第二阶段,制作可穿戴的纺织品微带贴片天线,将其集成并隐藏在服装中。仿真和制造测试结果表明,所设计的天线特性适用于fc = 2.40 GHz的工业、科学和医疗无线电(ISM)频段。织物基衬底的相对介电常数εr和厚度h对可穿戴微带贴片天线的辐射性能有显著影响。

Filtering the big data based on volume, variety and velocity by using Kalman filter recursive approach 采用卡尔曼滤波递归方法对基于体积、种类和速度的大数据进行滤波
Fatima Riaz, Muhammad Alam, Attra Ali
For the past seven decades the term Big Data is known, but due to the emerging technology shift of this era, it is captivating a lot of attention from the researchers of mathematics, computing, telecommunication, information technology, data warehousing, and mining. As this generation is living in the age of technology where data is playing a vital role and especially the Big Data has lots of success stories, but at the same time it is becoming the biggest threat to network service provider, telecom industry, and homeland security. Every device such as smart phones, laptop, desktop, etc. connected with the network is contributing to add data to a Big Data pool by using different applications. Social media such as Instagram, Facebook, WhatsApp, Apple, Google, Google+, Twitter, Flickr, etc. are few famous tools which are used to add redundant data. The question appears, is it mandatory to store and especially process all the data either useful or redundant? This research paper is focusing for filtering useful data from redundant data by using their parameters which are velocity, variety, and volume. In proposed architecture, Memcache DB (for velocity), Voldemort layers (for variety) and MapReduce (for volume) are linked with Hadoop to achieve filtered data. Kalman filter recursive approach is used to inject the data back into Hadoop Distributed File System to reduce processing cost of next iterations.
在过去的七十年里,“大数据”这个词一直为人所知,但由于这个时代的新兴技术转变,它吸引了数学、计算、电信、信息技术、数据仓库和挖掘等领域研究人员的大量关注。由于这一代人生活在技术时代,数据扮演着至关重要的角色,特别是大数据有很多成功的故事,但同时它也成为网络服务提供商、电信行业和国土安全的最大威胁。每一台连接到网络的设备,如智能手机、笔记本电脑、台式机等,都在通过不同的应用程序为大数据池添加数据做出贡献。社交媒体,如Instagram, Facebook, WhatsApp, Apple, Google, Google+, Twitter, Flickr等是少数著名的用于添加冗余数据的工具。问题出现了,是否必须存储和处理所有有用或冗余的数据?本文的研究重点是利用冗余数据的速度、种类、体积等参数,从冗余数据中筛选出有用的数据。在提议的架构中,Memcache DB(用于速度)、Voldemort层(用于多样性)和MapReduce(用于容量)与Hadoop相关联,以实现过滤数据。采用卡尔曼滤波递归方法将数据注入Hadoop分布式文件系统,以减少下一次迭代的处理成本。

Irfan Yousuf, Z. Shahid
The increase in electrical power requirements and impacts of conventional power generation on global climate is diverting the focus of researchers to green energy production. The conventional ways of power generation made an intensive carbon growth which widely contributes in the global warming. As a result, it is the vital need of time to take a strong initiative for the effective utilization of renewable energy resources.
