Image steganalysis is to discriminate innocent images and those suspected images with hidden messages. In this paper, we propose a unified Convolutional Neural Network (CNN) model for this task. In order to reliably detect modern steganographic algorithms, we design the proposed model from two aspects. For the first, different from existing CNN based steganalytic algorithms that use a predefined highpass...
Steganographer detection problem is to identify culprit actors, who try to hide confidential information with steganography, among many innocent actors. This task has significant challenges, including various embedding steganographic algorithms and payloads, which are usually avoided in steganalysis under laboratory conditions. In this paper, we propose a novel steganographer detection model based...
Recent studies have demonstrated that a well designed deep convolutional neural network (CNN) model achieves competitive performances on detecting the presence of secret message in digital images, compared with the classical rich model based steganalysis. In this paper, we propose to investigate a category of very deep CNN model–the deep residual network (DRN), for steganalysis. DRN is suitable for...
Noise exists universally in multimedia data, especially in Internet era. For example, tags from web users are often incomplete, arbitrary, and low relevant with the visual information. Intuitively, noise in the dataset is harmful to learning tasks, which implies that huge volumes of image tags from social media can't be utilized directly. To collect the reliable training dataset, labor-intensive manual...
An integrated simulation and optimization system code is being developed for China Fusion Engineering Test Reactor (CFETR). The main function of the CFETR system code is to achieve consistent physical objectives with achievable engineering parameters. As one of the most important works in a tokamak R&D, the design of divertor must consider many aspects, such as high heat loads removal, particles...
CFETR which stands for “China Fusion Engineering Test Reactor” is a new tokamak device. The mission and goal of CFETR are as follows: (1) ITER-like; complementary with ITER; (2) Fusion power 50–200 MW; (3) Duty cycle time (or burning time)∼(30–50%); (4) Tritium must be self-sufficiency by blanket. The main parameters of low temperature superconducting magnet system are as follows: (1) The central...
Because of no entity, no fixed life period, and the highly uncertainty of future benefits, compared with tangible assets, the identification and measurement of intangible assets are difficult problems in evaluating intangible assets. The concept of strategic readiness is first proposed by R. S. Kaplan in the paper "Measuring the strategic readiness of intangible assets". He used it to systematically...
This paper analyzes the characteristics of the traditional DEILPHI method, pointing out that the method has the shortcomings of strong subjectivity, complex data acquisition, and lack of real-time circumstance-specific solutions. It proposes an improved DEILPHI method based on objective preferences. According to the characteristics of evaluation indicators and the specific situation of actual evaluation...
A high demand of comprehensive quality upon scientific personnel is needed in modern society which mainly includes dominant quality and recessive quality. While humanistic quality and management quality are belonging to the above mentioned recessive quality; the two qualities play an important role in the culturing of high-level scientific personnel on behalf of universities of science and engineering...
There is a certain extent of the fuzzy measure with the value of samples and standards in evaluation. Based on the theories of the triangular fuzzy number (TFN) and the variable range fuzzy set, the model for fuzzy approaching degree of triangular fuzzy numbers is established. Then a new evaluation method based on variable range of triangular fuzzy number is proposed in this paper. After analysis...
There are many analyses and evaluating indexes in economics that are of great importance to an enterprise's optimum stock decision. Based on the analysis of these indexes, this paper tends to propose a method about ROA (return of assets) that could be used in analyzing an enterprise's running situation, and give a suggested calculating method and solvable idea as well to an enterprise's optimum stock.
