Abstract Association relationship and types between software service configuration parameters determine that the items must meet corresponding rules constraints in parameter value setting order. However, distribution of services architecture based on loose coupling heterogeneous components make association more concealed. The correlation are crucial to ensure system configuration. When deployin...

The air-lifting pump has the advantages of low cost, strong reliability, simple structure and convenient maintenance, especially in fields deep-sea mining, oilfield mining mineral under complex geological conditions. construction technology air intake mode not only play a decisive role performance pump, but also greatly hinder engineering application pump. Here, is taken as research object, riv...

Does the proof-of-work protocol serve its intended purpose of supporting decentralized cryptocurrency mining? To address this question, we develop a game-theoretical model where miners first invest in hardware to improve efficiency their operations, and then compete for mining rewards rent-seeking game. We argue that because capacity constraints faced by miners, centralization is lower than ind...

In this report we present a technology assessment of a spectrum of mathematical methods and software techniques for data mining, i.e., for nding patterns and regularities in sets of data. After an introduction to the subject, the second part of the paper describes the essentials of a variety of methods for data mining through supervised and un-supervised learning. In the third part of the repor...

In this paper, we review the past work and discuss the future of integration of data mining and relational database systems. We also discuss support for integration in Microsoft SQL Server 2000.

Spreadsheets can be viewed as a success story. Since the late seventies spreadsheet programs have been installed on the majority of computers and play a role comparable to text editors and databases management systems. Spreadsheets can be used to do anything with numbers, but are unable to handle process models and event data. Event logs and operational processes can be found everywhere. Recent...

The PlatoCAVE, the MiniCAVE, and the C2 are immersive stereoscopic projectionbased virtual reality environments oriented toward group interactions. As such they are particularly suited to collaborative efforts in data analysis and visual data mining. In this article, we provide an overview of virtual reality in general, including immersive projection technology, and the use of stereoscopic disp...
