The paper presents a test bed platform for implementation of Cloud Computing in SCADA systems for Electrical Power Systems. The general idea of the experimental study is to complete operation tests of traditional SCADA systems on cloud computing platforms, and integrate the main application modules of SCADA systems for electrical power metering on the cloud platforms. The logical networking structure...
Currently, cloud computing offers flexible, dynamic and cost effective computing outsourcing, but it limits these economic and operational benefits to non real-time and non safety-critical systems. This is because of the lack of alternative control, supported by current cloud infrastructures, in case of a broken cloud link. While steps have been taken in using cloud infrastructures for soft real-time...
With the rapid development of database and web technology, the way data organized and presented is becoming increasingly complicated while data sources are also intermingled with inaccurate information. Therefore, studies in truth discovery becomes overwhelmingly significant for it is critical for netizens to identify sources of high quality as well as to select the most accurate information from...
An important and widespread topic in cloud computing is text analyzing. People often use topic model which is a popular and effective technology to deal with related tasks. Among all the topic models, sLDA is acknowledged as a popular supervised topic model, which adds a response variable or category label with each document, so that the model can uncover the latent structure of a text dataset as...
In cloud investment markets, consumers are looking for the lowest cost and a desirable fairness while providers are looking for strategies to achieve the highest possible profit and return. Most existing models for auction-based resource allocation in cloud environments only consider the overall profit increase and ignore the profit of each participant individually or the difference between the rich...
An improved cloud resource revenue optimization models are proposed, which include the benefits of service providers and users negotiate SLA agreement. And the models define the constraint mechanism for describing service quality problems such as service response time and customer satisfaction. We design the comprehensive response indicator and use this indicator to quantify the rationality of the...
We propose a cloud based storage defragmentation technique in this paper. The cloud based defragmentation technique exhibits parallel concept of defragmentation. The proposed cloud based defragmentation technique involves defragment storage with less time consumption. Time graph is used to analyse memory access time using cloud based defragmentation technique. The comparisons have been depicted in...
Standby power refers to the electric power consumed by electronic appliances while they are in a standby mode. As the electronic appliance have become smarter, they consume more standby power. To reduce wasted electricity, techniques to save standby power have been developed in conjunction with network and communication technologies. Automatic standby power saving systems have been developed, but...
Software-defined radio (SDR) is used in several areas, such as the verification and implementation of radio prototypes. The SDR environment is generally configured with an analog-to-digital converter (ADC) and a personal computer (PC). However, since ADCs and PCs are fixed configurations, reconfigurations are needed in order to respond to different data sources and computing environments when the...
Recently cloud computing has ascended as a prevalent method for creating virtual computing labs (VCL) as it provides scalable, on-demand IT resources, which can be rapidly provisioned and utilized over the web. Higher Education Institutions (HEIs) around the world is in a constant state of change mainly as a consequence of globalization and challenges arising from adopting new technologies and pedagogies...
Cloud computing has been identified as a new paradigm in the field of computer networks services and has changed the way businesses interact with IT services by offering a strong base of virtualized services in both hardware and software platforms while delivering different on demand business models. This paper presents a new model of Cloud computing combined with E-Learning in schools and universities...
In this technological world one of the general method for user to save their data is cloud. Most of the cloud storage company provides some storage space as free to its users. Both individuals and corporate are storing their files in the cloud infrastructure so it becomes a problem for a forensics analyst to perform evidence acquisition and examination. One reason that makes evidence acquisition more...
Nowadays, more and more corporate and private users outsource their data to cloud service provider. It is provide lots of services to the users. Due to the large amount of data stored by multiple users on cloud one critical problem must be faced by users. In this large amount of data there are so many copies of repeated data. Data duplication is compress repeated data. We can use this technique To...
Virtualization technology is widely used for sharing the abilities of computer systems by splitting the resources among various virtual PCs. In traditional computer systems, the utilization of hardware is not maximized and the resources are not fully consumed. By using the virtualization technology, the maximum utilization of computer system hardware is possible. Today, many organizations especially...
Although cloud computing has made significant achievement, it still faces many challenges, such as slow interactive performance and unsatisfying user experience over a long-haul wide-area or wireless network. To address these challenges, we proposed a software-defined streaming-based code scheduling framework according to the concept of transparent computing. This framework uses the idea of code streaming...
Certification has been proved as an essential mechanism for achieving different security properties in new systems. However, it has important advantages; among which we highlighted the increasing in users trust by means of attesting security properties, but it is important to consider that in most of cases the system that is subject of certification is considered to be monolithic, and this feature...
Cloud Computing is a major field of study. Cloud Storage is regarded as an infrastructure to cloud computing and personal cloud storage are gaining popularity. This paper presents the development of a user friendly and efficient personal cloud synchronization and storage service using java and php. The application follows a new algorithm and its architecture is beyond the conventional client/server...
This paper presents a concept for an e-Science oriented opportunistic cloud computing service with QoS assurances, as an infrastructure to offer to researchers computing resources with the flexibility and ease of use of a cloud computing service, supported through the opportunistic use of the idle computing resources available in academic institutions, with mechanisms in place to address the low reliability...
Efficient surface soil moisture mapping is essential in precision agriculture application. Achieving efficient soil moisture monitoring is indispensable and meaningful. Cloud computing technology can enhance computational efficiency enormously. The geospatial web service was developed to assist agronomic decision making, and this tool can be scaled to any location and crop. By integrating cloud computing...
The concept of the cloud is no longer limited to providing remote hardware or platform support with the development of cloud computing technology. Instead, it encapsulates all aspects of the content in computer field into service invoked by others. As an important part of software, data resource has become core services to the cloud platform in areas such as collaborative manufacturing and collaborative...
