In determining how Cranial Electrotherapy Stimulation(CES)can best be used as a therapeutic tool, it is important to research its stimulating effect with the administration of various CES waveform shapes and frequencies. To meet CES research needs, this paper focused on designing a CES system outputting waveforms of arbitrary shape and different frequencies. The result showed that CES researchers...
Rolling bearings vibration signal is complex and non-stationary signal. In order to diagnose the bearing failures accurately and quickly, propose an approach about rolling bearing fault diagnosis, which is based on LS-SVM and LMD. Firstly, decompose the original vibration signal by LMD (Local Mean Decomposition LMD) to get a series of PF(Production Function, PF); secondly, establish the AR model of...
Traditional visual cryptography scheme has a shortcoming of size expansion of the revealed image. Usually, the expansion ratio m is not a square integer, and results in the variant aspect ratio of the revealed image. The large size expansion is not convenient for storage and transmission. In this paper, an improved aspect ratio invariant visual cryptography scheme with optional size expansion is proposed...
To study the the expression of ADAM8 (disintegrin and metalloprotease 8) during acute liver failure of mice induced by CCl4. The mice model of acute liver failure was established by CCl4 (0.1% in olive oil, 0.1mL/10g) abdominal injection. The liver pathological changes were observed at 0, 3, 6, 12, 24, 30, 36, 42, 48, 54h after CCl4 injection respectively. The expressions of ADAM8 protein were determined...
ADAM8 (disintegrin and metalloprotease 8) belongs to a family of transmembrane proteins implicated in cell-cell interactions, proteolysis of membrane proteins, and various aspects of carcinogenesis. In this study, we want to evaluate whether ADAM8 is highly expressed in liver cancer. So western blot, RT-PCR and Immunohistochemistry were used to evaluate the expression of ADAM8 in liver cancer and...
Face verification is defined as a person whose identity is claimed a priori will be compared with the person's individual template in database, and then the system checks whether the similarity between pattern and template is sufficient to provide access. In this paper we introduce a new procedure of face verification with an embedding Electoral College framework, which has been applied successfully...
Directly towards the influences of the two parameters granularity and water ratio on energy consumption, a series of molding experiment were carried out to investigate and determine the optimal granularity and water ratio corresponding to the minima energy consumption of typical crops straw. It was found that the optimal granularity is determined by physical characteristic of molding fuel and there...
In this paper, we develop an analyzing and evaluating robustness model of knowledge networks to capture the nature of robustness in the knowledge networks. We adopt 5 types of removing strategies based on knowledge flows to compare the robustness of knowledge networks, then analyze the robustness of knowledge networks under global and local information conditions. Simulation method was used to get...
How to improve the performance of an existing biometric system is always interesting and meaningful. In this paper, we present a novel method of score level fusion using multiple enrolled impressions to achieve higher verification accuracy of existing fingerprint systems. The main idea of the method is to build a representation of the biometric reference as a polyhedron by taking into account the...
Track initiation is an important part in multi-target tracking, especially for the lower observable targets under the condition of heavy clutter. Multi-Hough transform track initiation for detecting target with constant acceleration in heavy clutter environment is proposed. In this algorithm, standard Hough transform is used to filter clutter first. Then sift the candidate tracks by using randomized...
Based on the type analysis of manufacturing network alliance, this paper proposes that the manufacturing enterprise network alliance has a reasonable radius for cooperation production, and this is quite different from other kinds of alliance or mixed enterprise network alliance. When the reasonable radius is beyond the threshold, the partners' contribution to the alliance cooperation production will...
