Modern scientific instruments, such as detectors at synchrotron light sources, can generate data at 10s of GB/sec. Current experimental protocols typically process and validate data only after an experiment has completed, which can lead to undetected errors and prevents online steering. Real-time data analysis can enable both detection of, and recovery from, errors, and optimization of data acquisition...
Fault diagnosis of rotating machinery is receiving more and more attentions since it plays an important role in guaranteeing production efficiency and safety. In this paper, a novel method of fault pattern identification for rolling element bearing (REB) based on the time-wavelet energy spectrum with the Hermitian wavelet analysis, kernel principal component analysis (KPCA) and support vector machine...
Fine-grain data parallelism is increasingly common in mainstream processors in the form of long vectors and on-chip GPUs. This paper develops compiler and runtime support to exploit such data parallelism for non-numeric, non-graphic, irregular parallel tasks that perform simple computations while traversing many independent, irregular data structures, like trees and graphs. We vectorize the traversal...
4 Conclusion In this Chapter, we employed the 3D-FDTD method to calculate and evaluate the local electromagnetic field by investigating the effect of the surface geometry, the size, shape, and aggregation forms of nanoparticles on the SERS activity of transition metal systems. Our calculation on the cauliflowerstructured nanoparticles shows that the em enhancement is sensitive not only to the polarization...
Vector extensions, such as SSE, have been part of the x86 since the 1990s, with applications in graphics, signal processing, and scientific applications. Although many algorithms and applications can naturally benefit from automatic vectorization techniques, there are still many that are difficult to vectorize due to their dependence on irregular data structures, dense branch operations, or data dependencies...
With the increasing investment in the construction of power facilities and the use of higher voltage level, the noise generated by high voltage substation has become an unavoidable issue. The noise of the high-voltage substation is a mixture which is mixed by different noise sources. The mixed noise must be separated to several independent noise signals firstly for researching. An algorithm combined...
The anticipated 1000 fold increase in traffic demand over the next decade and the explosion of new services and applications, such as the internet of things (IoT), pose great challenges for the current 4G mobile network. Pattern division multiple access (PDMA), as a novel non-orthogonal multiple access scheme, has been proposed recently to address these challenges. The performance of PDMA uplink system...
Battery energy storage system(BESS) connected to the grid by power conversion system(PCS). Currently Cascaded Multilevel Converter(CMC) and Modular Multilevel Converter (MMC) are two more advanced topologies for PCS. This paper compares CMC and MMC topologies in aspects of efficiency, harmonic characteristics, reliability, control system complexity and cost, the simulation results are presented. Suggestions...
Content protection mechanisms are intended to enforce the usage rights on the content. These usage rights are carried by a license. Sometimes, a license even carries the key that is used to unlock the protected content. Unfortunately, license protection is difficult, yet it is important for digital rights management (DRM). Not many license protection schemes are available, and most if not all are...
Finite state machines (FSMs) are basic computation models that play essential roles in many applications. Enabling efficient parallel FSM execution is critical to the performance of these applications. However, they are very challenging to parallelize due to their inherent data dependencies that occur at each step of computations.
Intel Xeon Phi (MIC architecture) is a relatively new accelerator chip, which combines large-scale shared memory parallelism with wide SIMD lanes. Mapping applications on anode with such an architecture to achieve high parallel efficiency's a major challenge. In this paper, we focus on developing system for heterogeneous graph processing, which is able to utilize both a many-core Xeon Phi and a multi-core...
A model of dual-channel chaos laser communication system based on fiber transmission is proposed in this paper. The practical open-loop configuration at strong injection condition and the excellent symmetrical dispersion compensation scheme are applied in this model. The chaotic modulation (CM) and chaotic shift keying (CSK) methods are used to encrypt the message. The communication performances of...
Fine-grained data parallelism is increasingly common in mainstream processors in the form of longer vectors and on-chip GPUs. This paper develops support for exploiting such data parallelism for a class of non-numeric, non-graphic applications, which perform computations while traversing many independent, irregular data structures. While the traversal of any one irregular data structure does not give...
Coded structured light method was proposed for surface three dimension measurement, where two primary colors of red and blue were used to generate Gray code projecting patterns, with advantages of one unit Hamming distance and avoiding influence from the bright stripe to the dark one in grey coding. System mathematical model was established and simulation system was designed, then method and system...
Programmer productivity considerations are increasing the popularity of interpreted languages like Python. At the same time, for applications where performance is important, these languages clearly lack even on uniprocessors. In addition, the use of dynamic data structures in a language like Python makes it very hard to use emerging libraries for enabling the execution on multi-core and many-core...
Abstract: Convolution integral and convolution summation play an important role in the analysis of the linear time invariant systems. At present, many text books have published in my home country or foreign country , especially the ??sSignals and Systems??t all discuss the methods by use of the graph to determine the up limit, low limit and the interval of exist of the convolution integral or convolution...
Regulator is a common electronic device used to output stable voltage when the grid voltage fluctuate and load changes. The simulation and analysis of the series voltage regulator design based on Multisim 10 simulation software can help locating faults and shorten the design time, and provide an effective way to design series voltage regulator.
Invoices are the voucher to reimburse for official expenses. However, fake paper invoices spread in our lives. The appearance of electronic invoices can solve the problem of fake invoices. Before the business purchases invoices from Inland Revenue, The Inland Revenue and the business identify the authenticities of each other and generate a temporary session key between them through Key Distribution...
