In recent years, the obfuscation has been one of the most intriguing open problems in cryptography. Loosely speaking, an obfuscation O(P) of a program P should preserve P's functionality and its code remains ``unintelligent''. However, few positive results have been proposed. Hada et. al in EUROCRYPT'10 demonstrated an obfuscation of encrypted signature. Inspired by their work, We construct a structure-preserving...
Tensor decomposition of fMRI data has gradually drawn attention since it can explore the multi-way data's structure which exists inherently in brain imaging. For multi-subject fMRI data analysis, time shifts occur inevitably among different participants, therefore, shift-invariant tensor decomposition should be used. This method allows for arbitrary shifts along one modality, and can yield satisfactory...
This paper presents a study of regional effect on incubator function of innovation cluster from the perspective of knowledge management. First, the concept of Regional Incubator Function is defined. The reasons of both the birth and the development of the Regional Incubator and the effect of promotion of knowledge spillover are analyzed. Second, factors of the influence of the knowledge spillover...
Feature selection is an essential part of text categorization, which can effectively improve classification precision and efficiency. With some drawbacks proposed from traditional IG approach, an optimized approach that takes concentration and distribution into account is proposed for improving IG approach. The experimental results show that the improved IG approach is superior to traditional IG approach...
This paper studies off-line control and on-line control based on Adaptive Dynamical Programming and proposes an optimal adaptive algorithm with the combination of off-line and on-line training; The method using off-line value iteration algorithm gets off-line opitical controller, then using on-line policy iteration algorithm of Q learning improves the off-line opitical controller. Simulation results...
The deformation monitoring of landslide is an important content of the safety monitoring of landslide, it is one of the important tasks to make timely, reasonable and effective analysis for landslide observation data for getting the deformation regularities and the safety states of landslide, and the safety status and the stability of the landslide can be judged by the analysis results. The advanced...
The computation of Chinese sentence similarity has been widely used in many areas. However, due to the complexity of Chinese, currently, there have no corresponding algorithms to solve computation of sentence similarity at home and abroad. This paper represents an improved method of the computation of words similarity firstly, and then on this basis, the structure of semantic string has been given...
In order to compress calculation, the background estimation algorithm for the infrared target detection was proposed. Firstly, a Least Square Matrix is proposed and an image background is estimated. Then the target is detected by self-adaptive threshold detection in different images. It is shown by nonlinear function regression experiment and sequence infrared image detection experiment whose methods...
In this paper, we have used the data of some variables affecting current account balance and capital & financial account balance from 1985 to 2005 to generate some results. We have emphasized the Granger causality test and impulse response functions to analyze the dynamic influence of FDI to the capital and financial accounts, as well as the GNP of Pakistan. The results suggest that FDI has a...
To analyze the education of a school, the first thing is to analyze the whole teacher team of that school. How to measure the quality of the team and the personal qualities of team members, to understand the development trend of the whole team and the potential ability becomes very necessary. A well established data analysis system for teachers can provide both macro-data and micro-data analysis for...
Limited to the methods used before in designing logic circuits, not a same tool could be used to design both the combined circuits and the time-sequential circuits. The symmetrical coordinate system stated in this article can be constructed to represent various states of multi-dimensional logical variables. Using the symmetrical coordinate system, it is not only possible to complete the design of...
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing (STAP). In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance matrix (CCM) with and without channel mismatch is done based on the model provided by literature, and the effect to signal is also analyzed. In...
