Dynamic Proof of Storage (PoS) is a useful cryptographic primitive that enables a user to check the integrity of outsourced files and to efficiently update the files in a cloud server. Although researchers have proposed many dynamic PoS schemes in single-user environments, the problem in multi-user environments has not been investigated sufficiently. A practical multi-user cloud storage system needs...
In this paper, success degree fuzzy comprehensive evaluation(FCE) method is adopted for the post evaluation of success degree based on a library overhaul and energy-saving renovation project, evaluation results are acquired, detailed analysis are carried out, suggestions are put forward.
This paper studies the problem of planning collision-free dynamically feasible trajectories for a team of autonomous unmanned aerial vehicles (UAVs) in real-time, where the UAVs try to fly through a complex 3-D environment to reach their specified destinations. First, the cooperative trajectory planning problem is mathematically formulated as a decentralized receding horizon optimal control problem...
A new method is proposed in this paper to determine the harmonic contributions of multiple harmonic sources with consideration of the fluctuation of the background harmonic voltage. Affinity propagation and k-means clustering are used for determining each cluster of the harmonic measurement data, and the harmonic contributions of multiple harmonic sources are calculated by partial least-squares regression...
The effective assessment on the operation condition of power transformer is an important means to conduct the condition maintenance for transformer and to improve the reliability of power system. Based on the amount of information of all kinds of online monitoring conditions obtained from the transformer intelligent components, the assessment model for comprehensive condition of transformer is established...
With regard to the development of internal controls, there is lack of an index system of internal control evaluation for listed company. This largely constrains the study progress of listed company's internal control evaluation. To indicates the necessity of construct internal control evaluation system incorporate with the present condition of internal control for listed companies. Then construct...
Urban low-carbon competitiveness is closely related to environmental protection, low-carbon economy and sustainable urban development. The G20 Low Carbon Competitiveness report by Vivid Economics provides a fresh perspective. Commissioned by E3G and the Climate Institute (Australia), the report offers the first comparative, data-driven analysis of the low carbon competitiveness of major economies...
The domestic interior water body was monitored Based on an HJ-1 satellite multi-spectrum data. Chlorophyll a density is inverted from the empirical model based on the different area and different season. Suspension density inversion is based on the photobiology model of near-infrared waveband method. Based on chlorophyll a and the suspension density, the interior water body trophic level index is...
The assessment system for the water conservation is of vital significance to construct a water conservation society that is one of the most important strategies in the harmous development of social economy and ecological environment. According to the idea of ecological water footprint available, the evaluation system is established for the assessment of water conservation society based on water quality...
The increasing water demand directly results in the dwindling water supply in many cities of China. Water price plays an important role in the manage of urban water supply. The policy of laddered water price can reach the objective of water commodity pricing and establish the effective mechanisms with the core of water-saving, but it will face a practical problem due to for the lack of theoretical...
Internet users' evaluation about cities is an important basis for government's effective decision-making, and is also an important reference for upgrading city's image. Nowadays government mainly uses public sentiment monitoring on the Web to find all the aspects of cities' reputation and image, but it is hard to extract and analyze information effectively. So we use the opinion-mining and the step-by-step...
This paper proposes a novel network event correlation approach based on set covering. Firstly, we present a triple-layer belief network FPM by considering alarm loss and spurious faults into the bipartite graph FPM which used by IHU algorithm, then present the measurement of fault hypothesis. On basic of this model, we present a recursive algorithm for creating fault hypotheses. Compared with the...
