To explore the penetration depth with short-wavelength infrared light, 980nm pulse infrared light was used to stimulate the primary motor cortex of rat. The heating model was created to simulate the temperature distribution for 1875nm and 980nm infrared neural stimulation. Post-stimulus time histogram was used to observe the neural response induced by Infrared neural stimulation on primary motor cortex...
To explore whether the short wavelength near infrared laser can stimulate the functional hair cells, pulsed laser with wavelength of 808-nm was used to stimulate guinea pigs cochlea. Compound action potential (CAP) and auditory brainstem responses (ABR) were recorded during the experiments. We successfully recorded photomechanical responses from normal hearing animals and demonstrated the responses...
The spectrum of Time-Phase Modulation will spread because of its discontinuity in phase, and the bandwidth couldn't be assured so that common filters fail to filter meanwhile preserving available messages. This paper considers adopting notch filter which can transfer phase information into magnitude information, and the notch affect will promote the amplitude of discontinuity in phase to display within...
In this paper, Near-infrared spectroscopy (NIRS) was introduced into the field of Chinese herbal medicines and a rapid analytical method which can not only differentiate the two species of Fructus forsythiae, QingQiao (QQ) and LaoQiao (LQ), but also determine the contents of Phillyrin, Forsythoside A and Moisture in Fructus forsythia was established. The total content of volatile oil in Fructus forsythia...
In this paper, near-infrared spectroscopy (NIRS) combined with discriminant analysis was used as a qualitative tool to distinguish Fructus forsythiae from different geographical origins by collecting and analysing the NIR spectra in the range of 12000-4000cm-1. NIR spectra were analyzed by two methods: clustering analysis and discriminant analysis. In the former, the second derivative and Norris smoothing...
In today's society, it's a phenomenon that many other varieties of yam are pretended to be tie gun yam in the market. In this paper, Near infrared(NIR) spectroscopy combined with conformity test was used to establish a method which can quickly discriminate tie gun yam from other varieties. Firstly, the NIR spectra of 200 samples of yam, including 45 tie gun yam and 155 non-tie gun yam, were acquired...
Object tracking is a classic problem in the computer vision field. Its main purpose is to get the locations, the motion parameters, the trajectories and other information of the objects from the videos. An Adaboost tracking algorithm based on the particle framework is proposed in this paper. Due to the existence of high noises in the training samples, the difficulty of the AdaBoost training and the...
Using the finite element method, according to the actual size, building an entity model, the finite element simulation was conducted by a series of procedures, such as meshing, applying loads and solving. Then the temperature field and flow field with the three wires structure in the sensitive element were calculated in different tilting states. The results show that a heated hotwire forms definite...
The gas pendulum tilt sensor with the three wires structure was described. Using the finite element method, according to the actual size, building an entity model, the finite element simulation was conducted by a series of procedures, such as meshing, applying loads and solving. Then the temperature field and flow field with the three wires and two wires structure in the sensitive element were obtained...
The mechanism of the acceleration effects on the one-dimensional airflow level posture sensor was explained. Using the finite element method, the temperature field and the flow field in the sensitive element of the sensor under the effects on the different accelerations were calculated by a series of procedure, such as building model, meshing, applying loads and solving. The simulation result and...
In this paper we propose one method with a sequence of binomial data, utilize a stepwise confidence interval method for effectiveness study, and our method have more accurate confidence interval. Through employing our method, all the declarations can be guaranteed to be correct with a probability higher than 100(1−α )%. That is, the error rate is properly controlled.
The structural property of soft soil has important influence on the settlement of soft ground. It has been recommended in particular that the model of the structural property and the characteristic of plaxis soft and the application in calculating the settlement of soft ground. The plaxis soft can simulate the distortion process of the roadbed under load if modify the rational soil's model base on...
The purpose of this paper is to analyze and further optimize the JPEG image compression algorithm. First we analysis of JPEG image compression algorithm to achieve the specific methods with the advantages and disadvantages, at the same time, in the algorithm module in the sending, the output of a new data transfer mode was developed to reduce the error rate and enhance perform well in the data transfer...
Based on negation and negation as failure, in the paper, we propose a new rule language-fuzzy nonmonotonic semantic Web rule language (f-NSWRL), which suffices to represent and reason nonmonotonic fuzzy knowledge. The issue of priority is discussed and the deciding principles of priorities of competing rules are offered. To make RuleML play a role of an intermediary language when f-NSWRL interchanges...
The advanced technologies in the information age have instilled new energy to the experimental education. A new experimental education scheme for technical courses has been proposed, including education of experiment principles, Web-based presentation of experiment resources, preparation of experiments and its examination, virtual experiments and their examination, administration of open real experiments,...
The weakness of independent innovation capability has dramatically hindered most of the industrial clusters from promoting their sustainable competitiveness, however the weakness of enterprises' independent and technological innovation capability along with other problems have seriously set back the sustainable development of these industrial clusters. This article firstly analyzes why cooperative...
