The rapid proliferation, great user experiences but still limited computation ability of mobile, smart device platforms has forced the software developer to integrate mobile applications with existing computer software or web applications. To allow that integration, it needs a technology called web services which acts as an interface to communicate one application to other applications (machine-to-machine communication) in spite of the platform differences. By using web services, mobile applications can be able to access resources from computer software or web applications. This research is conducted to design a web services interface model for the existing software applications in Catholic Parahyangan University. This model covers several information system issues such as performance, security, reliability, independency, and scalability. To prove our model can be implemented, we develop several software prototypes for simulating the mechanism how the model works. For the next work, we expect the model to be implemented in the real environment.
移动、智能设备平台的快速扩散、出色的用户体验,但仍然有限的计算能力,迫使软件开发人员将移动应用程序与现有的计算机软件或web应用程序集成。为了实现这种集成,它需要一种称为web服务的技术,该技术充当接口,以便在平台不同的情况下将一个应用程序与其他应用程序进行通信(机器对机器通信)。通过使用web服务,移动应用程序可以从计算机软件或web应用程序访问资源。本研究旨在为天主教Parahyangan大学现有的软件应用程序设计一个web服务接口模型。该模型涵盖了几个信息系统问题,如性能、安全性、可靠性、独立性和可伸缩性。为了证明我们的模型可以被实现,我们开发了几个软件原型来模拟模型如何工作的机制。在接下来的工作中,我们期望该模型能够在真实环境中实现。

To increase education quality in rural areas, many researcher in Indonesia proposed Digital Learning as an alternative solution. Digital learning is constructed by utilizing information and communication technology (ICT) benefitting ICT main characteristics as a low cost, easy and quick deployment, and ease of operation and maintenance by using streaming video technology on Wireless Local Area Network (WLAN). Video streaming technology used WiFi or IEEE 802.11, specifically 802.11e MAC that supports Quality of Service (QoS). Several Digital Learning infrastructure built in Indonesia rural areas main problem is channel contention which caused a low throughput and affected the quality of video streaming. QoS provide a way to improve video streaming quality. QoS method for IEEE 802.11e is explained. Several studies proved video streaming quality can be improved using existing parameter in IEEE 802.11e. Model to implement and measure using existing parameter in IEEE 802.11e to improve video streaming quality for Digital Learning in Indonesia rural area is proposed in this paper.
为了提高农村地区的教育质量,印度尼西亚的许多研究人员提出了数字学习作为另一种解决方案。数字学习是利用信息通信技术(ICT),利用无线局域网(WLAN)上的流媒体视频技术,利用ICT低成本、易于快速部署、易于运维等主要特点构建的。视频流技术使用WiFi或IEEE 802.11,特别是支持服务质量(QoS)的802.11e MAC。印度尼西亚农村地区建设的几个数字学习基础设施的主要问题是信道争用,这导致了低吞吐量,影响了视频流的质量。QoS提供了一种提高视频流质量的方法。介绍了IEEE 802.11e的QoS方法。一些研究证明,使用IEEE 802.11e中现有的参数可以提高视频流质量。本文提出了利用IEEE 802.11e现有参数实现和测量的模型,以提高印度尼西亚农村地区数字学习的视频流质量。

Social networking become an essential part of life in both personal as well as professional relationships. We, therefore implement the pattern analysis of connections in a social media network. For more effective and faster connection suggestions on social networking websites we need to analyze connected networks on the basis of clustering and adaptive decision boundary techniques. The connection suggestion and classification based on minimum computation time in social networks has become an area of major interest. These algorithms occupy a lot of host machine resources to execute the bunch of nested threads that result in the overall speed reduction. Therefore we have seen the GPU is become an essential part of standard internet browsers to speed up the applications. If we want to run a simple decision boundary classifier application in real-time, either a very high speed processor along with bulk of free memory is required or some other parallel computing techniques should be used. In this paper, we are trying to take benefit from NVIDIA's GPU to build a robust classification technique for pattern recognition with adaptive decision boundaries using CUDA to ensure high speed connection suggestions and better network connection analysis.
社交网络成为生活中个人和职业关系的重要组成部分。因此,我们实现了社交媒体网络中连接的模式分析。为了在社交网站上获得更有效、更快速的连接建议,我们需要基于聚类和自适应决策边界技术对连接网络进行分析。基于最小计算时间的社交网络连接建议和分类已成为研究的热点。这些算法占用大量主机资源来执行一堆嵌套线程,从而导致整体速度降低。因此,我们已经看到GPU成为标准互联网浏览器加速应用程序的重要组成部分。如果我们想要实时运行一个简单的决策边界分类器应用程序,要么需要一个非常高速的处理器以及大量的空闲内存,要么应该使用一些其他的并行计算技术。在本文中,我们试图利用NVIDIA的GPU,利用CUDA构建一个具有自适应决策边界的模式识别鲁棒分类技术,以确保高速连接建议和更好的网络连接分析。

In this paper we use the concept of co-design and human information system to suggest the doctors, colleagues and patients (DCP) social network that enables communication between clinics, doctors and patients; and among the doctors to improve the standard. We propose a DCP social network architecture based on the cloud computing and two algorithms. The first algorithm initializes the working group list into the proposed P2P network and integrates them with current network such as Swedish National projects (NPO). The second algorithm enables user to search DCP social network using criteria such as near distance and location. In DCP social network, how patients make judgments in selecting their physicians interpret the important aspects which are not only the way patients relate to the information system but also what the role of intelligent DCP social network in healthcare sector. Experimental results show that the proposed method based on DCP social network which requires co-designing has the execution time less than that of traditional Azure P2P network. As a second contribution, WG list helps to control the growth of DCP social networks nodes.
本文运用协同设计和人类信息系统的概念,提出了医生、同事和患者(DCP)社会网络,实现了诊所、医生和患者之间的沟通;并在医生之间提高水平。提出了一种基于云计算的DCP社交网络架构和两种算法。第一个算法将工作组列表初始化到提议的P2P网络中,并将其与现有网络(如瑞典国家项目(NPO))集成。第二种算法允许用户使用距离和位置等标准搜索DCP社交网络。在DCP社会网络中,患者如何做出选择医生的判断,不仅是患者与信息系统的联系方式,也是智能DCP社会网络在医疗保健领域的作用。实验结果表明,该方法基于需要协同设计的DCP社交网络,执行时间少于传统Azure P2P网络。作为第二个贡献,WG列表有助于控制DCP社交网络节点的增长。

This paper deals with social network approach to understand an organizational management problem. Four groups of factors, i.e., workplace spirituality, affective commitment, continuance commitment and normative commitment are used to quantify the level of organizational commitment. In total, there are forty measurements representing those factors. To analyze which factors that strongly influence the level of organizational commitment, social network approach is used where each measurement is considered as a member of social group and the relationship among them as social relationship. To illustrate the advantage of this approach, a case study on the level of organizational commitment in Malaysia will be presented and discussed.

Mobile application providing access to some Online Social Network (OSN) services like Facebook and Twitter had been launch bundled with a data access subscription plan. At the end of 2010, the user of the application increased significantly to more than two millions subscribers while the number of active users grew slowly for only about 300.000 users per month. This research was conducted to see how the user use the OSN application. This research utilized the data collected from user's profile, transaction log and activity log from the service provider. The result was then analyzed using descriptive statistics to discover the pattern of user's behavior of the mobile online social network application. Authors found that user's behavior of mobile online social network service was almost the same as other online social network service users but with special characteristics since mobile users tend to have close session-tosession interval and might have longer session duration. This study will give the service provider recommendation to define better strategy for future development and improvement. The result can also be a reference for another similar research on mobile online social network application in the future.
可以访问Facebook和Twitter等在线社交网络(OSN)服务的移动应用程序已经与数据访问订阅计划捆绑在一起推出。2010年底,该应用的用户数量大幅增长至200多万订户,而活跃用户数量增长缓慢,每月仅约30万用户。这项研究是为了了解用户如何使用OSN应用程序。本研究利用了从服务提供商的用户配置文件、事务日志和活动日志中收集的数据。然后使用描述性统计对结果进行分析,发现移动在线社交网络应用程序的用户行为模式。作者发现,移动在线社交网络服务的用户行为与其他在线社交网络服务的用户行为基本相同,但具有特殊的特征,因为移动用户往往具有较近的会话间隔,并且会话持续时间可能更长。本研究将提供服务提供者建议,以确定更好的策略,以供未来的发展和改进。研究结果也可为今后类似的移动在线社交网络应用研究提供参考。

Wireless Local Area Network (WLAN) based on IEEE 802.11e provides Quality of Service (QoS) support at the Medium Access Control (MAC) sublayer. IEEE 802.11e MAC sublayer uses a function called Hybrid Coordination Function (HCF) with Enhanced Distributed Channel Access (EDCA). EDCA is a QoS mechanism that provides a priority scheme by differentiating interframe space and contention window size, it also uses Contention Free Bursting (CFB) scheme that can improve the efficiency of the system. In this study we analyzed performance of wireless network based on IEEE 802.11e in supporting QoS for multimedia transmission. We use three different types of traffic, those are voice, video, and data to analyze the performance of the network in supporting multimedia transmission.
基于IEEE 802.11e的无线局域网(WLAN)在介质访问控制(MAC)子层提供QoS (Quality of Service)支持。IEEE 802.11e MAC子层采用了混合协调功能(HCF)和增强型分布式通道接入(EDCA)。EDCA是一种通过区分帧间空间和争用窗口大小来确定优先级的QoS机制,它还采用了争用无爆发(CFB)机制来提高系统的效率。本研究分析了基于IEEE 802.11e的无线网络在支持多媒体传输QoS方面的性能。我们使用语音、视频和数据三种不同类型的流量来分析支持多媒体传输的网络性能。

In this study we analyzed performance of wireless network based on IEEE 802.11e in supporting QoS for multimedia transmission. We use three different types of traffic, those are voice, video, and data to analyze the performance of the network in supporting multimedia transmission.","PeriodicalId":102811,"journal":{"name":"2012 International Conference on Cloud Computing and Social Networking (ICCCSN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121524644","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}
