Visualization of the micro video big data refers to the intuitive display of the obtained data on micro videos across the Internet for the purpose of helping users to understand the message in the data. This paper describes the implementation of a micro video big data visualization system in detail, which has four steps: determine the visualization objective, choose data based on the objective, display...
Modern applications are increasingly being composed from multiple components that require and consume services at dierent layers of the cloud stack. The diverse, dynamic and unpredictable nature of both cloud services and application workloads makes quality-assured provision of such cloud service-based applications (CSBAs) a major challenge. While elasticity and autoscaling gives CSBA providers the...
When Business support systems (BSS) suffer poor performance, the system administrator has to spot the problem of BSS as soon as possible. The monitoring system is a great help to quickly gain insight of the system from all sides. By the monitoring system, the administrator can evaluate various metrics on the different fields in one single arranged page and understands the whole picture of current...
Combining enterprise architecture and operational data is complex (especially when considering the actual 'matching' of data with enterprise architecture objects), and little has been written on how to do this. Therefore, in this paper we aim to fill this gap and propose a method to combine operational data with enterprise architecture to better support decision-making. Using such a method may result...
In recent years, the technology of Cloud Computing has been developed rapidly. It makes IT infrastructure available as a service through the network. Using Cloud Computing, users can find a new effective solution for building systems and applications according to their demands. How to make the existing services reliably run on the cloud platform, and satisfy the high scalability and availability requirements...
Parallel applications rely on I/O to load data, store end results, and protect partial results from being lost to system failure. Parallel I/O performance thus has a direct and significant impact on application performance. Because supercomputer I/O systems are large and complex, one cannot directly analyze their activity traces. While several visual or automated analysis tools for large-scale HPC...
One central task to the idea of Semantic Web is reasoning over semantic descriptions of web pages and information items available on the Web. A flagship project that is advancing the state of the art in reasoning with Web scale data is the Large Knowledge Collider (LarKC). Having a plug gable architecture, LarKC enables the interested users to test their reasoning approaches with very little overhead...

Data gathered from sensor networks can easily reach the dimension of millions of data points. While there exists a great variety of sophisticated components for web-based data visualization, efficient and timely data retrieval is a non-trivial problem when dealing with large data sets. In this paper, we present a client-server architecture for a web application that allows a user to interactively...
The paper presents a problem of Real Time processing of ECG signal from patients by mobile embedded monitoring stations. Two ECG measurement devices were used in real tests. A two ECG channel bipolar ECG CorBelt and a 12 channels ECG device BlueECG. Both devices are products from CorScience Company. Due to a problem of processing a 12 channels ECG from ECG device by Bluetooth to mobile stations, the...
This paper describes development of a biotelemetric system and problem of real time processing of ECG signal. In this case of signal processing ECG CorBelt primarily on mobile embedded monitoring stations. The Whole system is based on Microsoft product as Windows Mobile, Microsoft SQL Server, .NET Micro Framework, .NET Compact Framework and .NET Framework. On paper is deal with ECG measurement devices...
