Today, the dominant topic of Information Technology's development are social media and cloud computing. Based on statistical data, a social networking or social media can have up to hundreds millions of active users. The amount of data users will precisely impact on investment in infrastructure to support IT services. Regarding to that condition, Cloud computing technology with the paradigm that seeing IT as a Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) is expected to deliver IT Investment's cost reduction. Geosmart social media is an interactive, informative and communicative media for education, with the objective is to increase the intelligentsia of all level of generations in Indonesian society. Lectures, students, Alumni, and Parents are the main target as the users.

This paper describes the design of evaluation system for evaluating virtual class service. This system will be used for evaluating the virtual class in rural areas where the network capacity is limited. This virtual class service has been implemented in rural area where the users are the students of elementary school and teachers. The satisfaction of users is the most important thing that must be accounted to evaluate the success of service. The evaluation system is being designed using SERVQUAL methodology. SERVQUAL is a method for measuring user satisfaction. It compares between the expectation and user perception of one service. This is a quantitative method where the user of virtual classroom will give score of their expectation and perception. There are some aspects that will be measured using this method, they are tangibility, reliability, responsiveness, assurance and emphaty. However, to ensure the validity of the measuring of these aspects, the SERVQUAL questionaire must be designed well and easily to understand by the user. The purpose of this paper system is designing a web based system that can be used to evaluate the virtual class that has being operated so far using SERVQUAL methodology as a basis for the system. The user satisfaction is the most important key factor for the success of IT services.

The use of multimedia applications is increasing every year. These trends include the deployment using wireless local area network (WLAN) that allows users to access various services. The most significant thing in the use of wireless networks is the delay, collusion, attenuation and interference. In addition, it is difficult to provide quality of service (QoS) in WLAN as the network capacity also varies with the offered load [1]. There are several problems in QoS support for multimedia applications. For real-time multimedia applications, packet loss and packet drop due to excessive time delay is a major factor affecting the quality perceived by the user. For video streams, delay is a very important factor to consider when transmitting the entire video frame from the sender to the client. Level of losses incurred due to packet delay depends on the delay data transmitted in the form of a video stream. Video streaming applications usually impose an upper limit (threshold) packet loss. In particular, packet loss ratio required to be kept below the threshold for achieving an acceptable visual quality. Packet loss ratio is high due to network congestion or network traffic is very high (overload) that cause degradation of the quality of multimedia, especially in wireless networks with limited bandwidth. To reduce the rate of degradation is the necessary framework of adaptive mechanisms in the wireless network so that video streaming applications such as teleconferencing can work well.

The complexities of research in science have been increasing extremely. Numerous mathematical models have been developed. Matrix has been used popularly to model numerous and complex science and engineering problems. It is found that as the dimension of the matrix grows in size, the complexities of matrix computation increase. This problem may be solved by using large computer system (i.e. mainframe). However, its operational is very costly. Another solution is to utilize parallel computing, which are able to cut off the operational cost. A recent advance in parallel programming is the introduction of MapReduce, as a new approach in parallel programming. MapReduce can perform calculations with distributed method by utilizing an idle processor. In this research, the performance of MapReduce in matrix operation is compared to other conventional methods, which are Single Processor and Threads. The performances are assessed by comparing the execution time, CPU usage, and RAM usage of each approach. The results show that MapReduce performed better than the other approaches.

This research paper describes study of the lung diseases diagnosis software with Influenza and Tuberculosis as the cases study. Influenza is a highly contagious infection of the respiratory tract. In Indonesia, numerous number of Avian-Influenza (H5N1) cases occurred in rural area, such as cases in Garut, Jawa Barat in 2006 which started in Cikelet district causing 14 infected-cases and 5 death-cases and has put Garut in an emergency situation until 2010. The H5N1 detection in rural area requires fast yet accurate diagnosis result to enable immediate curative actions. The most accurate result is provided by RT-PCR (Reverse-Transcription Polymerase-Chain-Reaction), which is high investment, and usually locates in urban area. Another diagnostic tool, rapid diagnostic test, is most common tool but gives inaccurate result because of its low sensitivity and specificity. In case of Tuberculosis, Indonesia ranks number 3, after India and China, as a country with most number of infected-people. Symptoms are chronic-cough with blood-tinged-sputum, fever, night-sweats and weight-loss. Tuberculosis is diagnosed by identifying Mycobacterium-tuberculosis organism in clinical sample. When this is not possible, probable diagnosis may be made using imaging X-rays or scans, tuberculin skin test and/or Interferon-Gamma-Release-Assay (IGRA). The main problem with tuberculosis diagnosis is difficulty in culturing this slow-growing organism in laboratory, which may take 4 to 12 weeks for blood or sputum-culture. The requirement is to create a first-hand diagnostic tool which allows paramedic mobility to rural areas for Influenza/Tuberculosis diagnostic purposes. The study first introduces lung auscultation method, then analysis and preliminary design of lung diseases diagnosis software. To enable each Lung Health for Public Council (Balai Besar Kesehatan Paru Masyarakat) and Health Service Office (Dinas Kesehatan) within province/region/country as data owner to maintain its own data, and to provide the data confidentiality as well, the cloud computing environment is then applied.
本文以流行性感冒和肺结核为研究对象，对肺部疾病诊断软件进行了研究。流感是一种高度传染性的呼吸道感染。在印度尼西亚，许多禽流感(H5N1)病例发生在农村地区，例如2006年在贾瓦巴拉特加鲁特的病例，该病例始于Cikelet县，造成14例感染病例和5例死亡病例，并使加鲁特处于紧急状态，直到2010年。在农村地区发现H5N1需要快速而准确的诊断结果，以便能够立即采取治疗行动。RT-PCR (Reverse-Transcription Polymerase-Chain-Reaction，逆转录聚合酶链式反应)是最准确的检测方法，该方法投资高，通常位于城市地区。另一种诊断工具是快速诊断试验，它是最常用的诊断工具，但由于其灵敏度和特异性较低，结果不准确。就结核病而言，印度尼西亚排在印度和中国之后，是受感染人数最多的国家。症状是慢性咳嗽带血痰，发烧，盗汗和体重减轻。结核病是通过临床标本中结核分枝杆菌的鉴定来诊断的。当不能这样做时，可能的诊断可使用成像x射线或扫描、结核菌素皮肤试验和/或干扰素- γ释放试验(IGRA)进行。结核病诊断的主要问题是难以在实验室培养这种生长缓慢的有机体，可能需要4至12周的血液或痰培养。要求是建立一种第一手诊断工具，使辅助医务人员能够前往农村地区进行流感/结核病诊断。本研究首先介绍了肺部听诊方法，然后对肺部疾病诊断软件进行了分析和初步设计。为了使省/地区/国家内的每个肺健康公共理事会(Balai Besar Kesehatan Paru Masyarakat)和卫生服务办公室(Dinas Kesehatan)作为数据所有者维护自己的数据，并提供数据机密性，然后应用云计算环境。

Spectrum sensing method for cognitive wireless cloud computing (CWC) network is very challenging since there are several different communication systems should be detected at very low SNR (as low as -22 dB). In this paper, we propose a kurtosis based spectrum sensing method which can be applied efficiently in such environment. The proposed method uses kurtosis estimation of received samples. Its value will be equal or close to 3 when only gaussian noise samples exist in the received signal. This kurtosis estimation's used to distinguish between the present or absent of primary signal by comparing with a predefined threshold. Simulation's done to evaluate its performance. Results show that the proposed method performs much better than energy detection especially at low SNR, even below -20 dB. It also gives benefit in much simple implementation for CWC network since it doesn't need knowledge of primary signal's parameters.

In this paper, we propose a kurtosis based spectrum sensing method which can be applied efficiently in such environment. The proposed method uses kurtosis estimation of received samples. Its value will be equal or close to 3 when only gaussian noise samples exist in the received signal. This kurtosis estimation's used to distinguish between the present or absent of primary signal by comparing with a predefined threshold. Simulation's done to evaluate its performance. Results show that the proposed method performs much better than energy detection especially at low SNR, even below -20 dB. It also gives benefit in much simple implementation for CWC network since it doesn't need knowledge of primary signal's parameters.","PeriodicalId":102811,"journal":{"name":"2012 International Conference on Cloud Computing and Social Networking (ICCCSN)","volume":"97 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":"127783237","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}
