Digital watermarking technology is an effective measure for copyright protection. This paper presents the design of a Flash digital watermarking application which is implemented using the Graphic User Interface (GUI) function of the MATLAB software. The application can open and play Flash animations as carriers, it can embed watermark images into the carriers and extract watermarks from the Flash...
Currently, connectomes (e.g., functional or structural brain graphs) can be estimated in humans at ≈ 1 mm3 scale using a combination of diffusion weighted magnetic resonance imaging, functional magnetic resonance imaging and structural magnetic resonance imaging scans. This manuscript summarizes a novel, scalable implementation of open-source algorithms to rapidly estimate magnetic resonance connectomes,...
Data analyzing and processing are important tasks in cloud computing. The MapReduce can provide a cost-effective, flexible, fault-tolerant and scalable distributed programming model over large clusters. However, how to implement join operation using MapReduce efficiently is an attractive point. Data skew problem has a strong impact on the performance of join operation. In this paper, we implement...
Data analyzing and processing are important tasks in cloud computing. The MapReduce framework has been increasingly used to analyze large-scale data over large clusters. Compared with parallel relational database, it has the advantages of excellent scalability and good fault tolerance. However, its performance is not as good as that of parallel relational database. How to efficiently implement join...
Privacy preservation has recently received considerable attention in location-based services. A large number of location cloaking algorithms have been proposed for protecting the location privacy of mobile users. However, most of existing cloaking approaches assume that mobile users are trusted. And exact locations are required to protect location privacy, which are just the information mobile users...
Software-as-a-service emerges as a new delivery model for the software development and applications. In multi-tenancy applications, tenants can customize and adjust the corresponding services shared by tenants based on their business requirements with strong elasticity and expansibility. As services do not exist independently, the resolving of service dependencies in practical multi-tenancy applications...
The bispectrum and 1(1/2)dimensional spectrum analysis is introduced, then this method is applied to the fault diagnosis of blower. Through the nonlinear phenomenon of quadratic phase coupling is detected by the bispectrum character, and 1(1/2) dimensional spectrum analysis can extract the fault characters of vibration data of blower. The drawback of the STFT analysis, restrictions of frequency resolution,...
The microgrid can address the technical and commercial challenge of integrating distributed energy resources into the bulk electric grid, and also provide an effective approach to reducing the consequences of natural disaster (e.g. earthquake, hurricane and snowstorm). The microgrid features and its applications to emergency response and disaster relief are first presented in this paper. A control...
