Correlation Electromagnetic analysis (CEMA) has been effective in revealing the cryptographic key on cryptosystems. Random delay insertion (RDI) causes misalignments to prevent the action of these attacks in the time domain to avoid information leakage. In this paper, we first use the newly proposed time-frequency transformation Hirschman Optimal Transform (HOT) to transform the signal from the time...
Rumormongers always use long paragraphs to spread slanderous stories so that they can convince readers. Those illegal or sensitive rumors uploaded into the internet can be written on images to by-pass text filters. These images can be detected by existing filters such as OCR, but the detection is very time consuming. To prohibit the dissemination of those commentaries, detecting whether an image contains...
In recent years, there are growing interests in developing novel approaches for inferring dynamic interactions in biological systems including gene transcription network and microbial interaction networks. Multivariate Vector Autoregression (MVAR) model is one of these efficient methods. Variants of MVAR with different penalties or regularizations can avoid the problem of over-fitting and provide...
Correlation coefficients are dominant indexes of measurement instrument quality. Among the varieties of correlation coefficients Pearson product moment correlation coefficient is the most popular. That is why intraclass correlation attracts relatively less relation. But in certain conditions, Pearson product moment correlation coefficient is not effective and intraclass correlation takes advantage...
Snowmelt runoff is one of the most important components in water resources across the source region of the Yellow River, Timing of snowmelt runoff may be influenced greatly by warmer weather. March to May from 1980 to 2006, obtained from passive microwave remote sensing data SSMR and SSM/I, timing of the Center of Mass for Flow(CT) was used as a proxy of timing of snowmelt runoff with daily stream...
It depends on the revenue allocation that the stakeholders of construction project can cooperate harmoniously or not for it can reduce the conflict among the stakeholders and construction resources if the income can be distributed reasonably.With the use of game theory, this paper has created a rational revenue allocation model and determined the non-egalitarian distribution coefficient on the basis...
Random process variations are often composed of location dependent part and distance dependent correlated part. While an accurate extraction of process variation is a prerequisite of both process improvement and circuit performance prediction, it is not an easy task to characterize such complicated spatial random process from a limited number of silicon data. For this purpose, kriging model was introduced...
Image fusion techniques can integrate the spatial detail of the panchromatic image and the spectral characteristics of the multispectral image. Intensity-hue-saturation (IHS) transform and wavelet transform are widely used in the existed fusion methods. The fused image will appear significant color deviation from the original image when using them separately. In this paper, we propose a new IHS and...
Most Earth observation satellites provide both panchromatic images with a higher spatial resolution and multispectral images with a lower spatial resolution. Image fusion techniques can integrate the spatial detail of the panchromatic image and the spectral characteristics of the multispectral image into one image Exiting image fusion techniques such as the Intensity-Hue-Saturation (IHS) transform...
130 wet deposition events were observed at the summit of Mt. Tai (East China, 1534 a.s.l) in China during Jan. 2005 to Dec. 2008. Zn, Al, Mn, Fe, Pb, Cu, Ni, Cr, As, and Cd were determined by ICP-MS to evaluate the characteristics of heavy metals in wet deposition at Mt. Tai region. The concentrations of these metals are generally higher at Mt. Tai than the concentrations observed at other monitoring...
In the area of hyperspectral image detection, Constrained Energy Minimization (CEM) algorithm has received considerable interest recently. However, it is very sensitive to noise and can only detect one target at one time. In order to solve this problem, Winner-Take-All Constrained Energy Minimization (WTACEM) was proposed. Based on it, we propose a modified multi-target detection approach. We study...
Numerical Simulation of the interaction between Intracranial Pressure (ICP) and Cerebral Blood Flow (CBF) based on physiology and hemodynamics is presented. The circulation of the cerebral blood and the circulation of the cerebrospinal fluid are considered in this model. The model includes the main biomechanical factors assumed to affect intracranial pressure, particularly cerebrospinal fluid (CSF)...
Existing approaches to statistical leakage analysis focus only on calculating the mean and variance of the total leakage. In practice, however, what concerns most is the tail behavior of the sum distribution, as it tells that to what extent the design will be safe or reliable. However, computing the tail distribution is much more difficult than computing the mean and variance. In this paper, we tackle...
According to the foreign research, small and medium-sized high-tech enterprises growth influence factors are get. Based on the large questionnaire investigation and using comparison analysis method, main factors that influence the growth of Dalian small and medium-sized high-tech enterprises is discussed. Through research, high-speed growth small and medium-sized high-tech enterprises and low-speed...
In this paper, a covariance-based algorithm with multiple antennas is proposed to eliminate the follower jamming for frequency hopping systems (FH) by finding the interference-blocking filter over quasi-static flat fading channels. The system uses the auto-covariance matrix of the received signal and M-array receive antennas. The simulation results show that the proposed approach can estimate the...
Nowadays mainstream RDF Repository Systems are based on RDBMS. The SPARQL query engine translates a SPARQL query into a SQL one, and then the RDBMS executes the SQL query. However the RDBMS optimizers, which usually assume that columns are statistically independent, often underestimate the selectivity of conjunctive predicates and choose a bad query execution plan. It is important for query optimizers...
Taking account of the deficiency in whole body measurement and in the traditional segment measurement methods, a new trunk subdivision model is established and preliminary experiment is carried out. The trunk subdivision model avoids the undesirable effects from chest and abdomen on fat measurement. A measuring system based on the model is developed. The results of the fat distribution and content...
Harmful algae in source water become a very serious problem for water plants in China. Artificial neural networks (ANN) have been successfully used to model primary production and predict one-step weekly algae blooms in reservoir. In this study, to avoid selecting inputs randomly during the establishment of feed forward ANN forecasting algae two days later, we use correlation coefficient and index...
In this paper, we apply the least-square support vector machine (LS-SVM) to operon prediction of Escherichia coli (E.coli), with different combinations of intergenic distance, gene expression data, and phylogenetic profile. Experimental results demonstrate that the WO pairs tend to have shorter intergenic distances, higher correlation coefficient and much stronger relation of co-envoled between phylogenetic...
