Bayesian Network has an advantage in dealing with uncertainty. But It is difficult to construct a scientific and rational Bayesian Network model in practice application. In order to solve this problem, a novel method for constructing Bayesian Network by integrating Failure Mode and Effect Analysis (FMEA) with Fault Tree Analysis (FTA) was proposed. Firstly, the structure matrix representations of...
In the field of milk quality testing, the technology of the ratio of scattered intensity to transmitted intensity has become a hot topic. In general, the particle size of fat globules after homogenizing is supposed to be the same. In fact, there is still the particle size distribution. The image processing technique is used for processing and analyzing the image of milk fat, in this paper. The results...
Electrical modeling of through silicon via (TSV) is very important for three dimensional (3D) system design and analysis. In this paper, we present our study on the impact of sidewall roughness on the TSV electrical performance in the ultra-broad band range. Our analysis shows that the root mean square height of the rough sidewall is comparable to the skin depth in extremely high frequency (> 20G...
In our previous research, a novel portable pneumatic power source, called a Dry Ice Power Cell was developed. In this paper, an improvement in design of the Dry Ice Power Cell is presented, and the thermodynamics analysis of Dry Ice Power Cell is also done. When dry ice is stored in the confined pressure container, it begins to liquefy. Then the liquid carbon dioxide will flow into Dewar flask to...
In order to improve the verification efficiency of electronic thermometer in manufacturer, a plan of image processing system applied to batch electronic thermometer verification is presented. For the purpose of solving the key techniques of batch electronic thermometer verification in manufacturer, the readings device applied to batch electronic thermometer verification, image processing technique,...
Most existing methods of image classification ignore the role of depth information hidden in 2-D images. However, the depth information is important for visual perception, especially when the appearance information does not perform well. In this paper, we propose to embed depth information within multiple pooling into the classic platform of image classification, namely bag-of-features. The proposed...
The threshold current of semiconductor laser will increase with increasing temperature, while the output power is decreased. Currently, domestic low-power semiconductor laser power stability is more than 1 percent. Comparison with the current level of domestic market, and in order to stabilize laser power, this paper presents the circuit of laser automatic power control (APC), and through improving...
It is the key for MOEMS accelerometer to combine large mass, weak spring and sub-wavelength gratings in order to achieve high precision. A novel out-plane MOEMS accelerometer based on near-field evanescent waves coupling by means of variable period sub-wavelength gratings has been proposed. Structure parameters were optimized by finite element analysis to achieve high sensitivity in an ideal vibration...
The vehicle identification is a key technology of vehicle automatic driving and assistance systems. This paper proposes a new fast vehicle detection method based on feature learning and real-time prediction by combining ARMA model and AdaBoost algorithm, which can be applied in car driver assistance systems for road detection and vehicle identification with a monocular camera. Experimental results...
This paper addresses a rescheduling problem in a robotic cell where a material handling robot is responsible to transport parts from one workstation to another and the different jobs (parts) arrive at the cell randomly. Our objective is to minimize the total completion time of all the jobs by dynamically changing the current schedule. Following a robotic rescheduling framework to find a new schedule,...
Image mosaicing is a common method in Medical image processing. In this paper, a new method is proposed for image mosaicing based on Speeded-Up Robust Features (SURF), which can be used for X-ray images of spine. First, feature descriptor of the image is obtained by using SURF; secondly, matching pairs are found, check the neighbors, and remove the mismatch couples by RANSAC (Random Sample Consensus);...
The atrophic changes in mild cognitive impairment (MCI) have been proposed as biomarkers for detection and monitoring. This paper analyzed magnetic resonance imaging (MRI) to identify the atrophy regions of the whole brain grey matter (GM) in longitudinal MCI group. Based on the method of voxel-based morphometry (VBM), the two-sample t test was performed to compare MCI (n=21) in the initial stage...
Random initial cluster center k-Means algorithm is applied to analyze the chemical composition of the native Kaolin, which is similar to the native kaolin and is classified into one class. This paper is to find the alternative echelon of native Kaolin from the obtained experimental results. According to the principle of similar Kaolin replacing each other, the paper solves the problem of insufficient...
Spatial-temporal characteristics analysis of an isolated on-ramp is carried out by using a new cellular automation model, which could describe the synchronized traffic flow. Simulation results show that five different kind of spatial-temporal patterns can be found in this model induced by an isolated on-ramp. A statistical research of flux and velocity for each patterns are investigated. All simulation...
This study investigated the texture features and volumes of bilateral hippocampus and medial temporal lobe (MTL) in magnetic resonance imaging (MRI) in patients with Alzheimer's disease (AD). Texture features were extracted using gray level co-occurrence matrix (GLCM) in 29 elderly AD patients, 19 age-matched non-demented controls (EC) and 18 young healthy controls (YC). The correlation between texture...
This paper presents an application of the lane reservation strategy in the hazardous materials transportation. Once an accident of hazardous materials transportation happens, its effect is significant. Lane reservation can reduce the hazardous materials transportation risk enormously; however, it will also impact on the normal traffic. The proposed problem is to choose lanes to be reserved on the...
As data rates increase, it is necessary to de-embed the effects of structures between the device-under-test (DUT) and the probe tips to accurately characterize the DUT. This work proposes that once a 4-port device is measured using off-wafer calibration, numerical post-processing of the measured data via a second-tier calibration, such as multiline TRL, can remove end-effects and set the reference...
Now that in language with garbage collection (GC) mechanism such as Java, the GC should be a direct impact on the performance of the program, and the requirement of real time GC is even higher in a real-time system. We proposed a memory reclamation scheme based on semi-space GC to satisfy the demands of real-time system. In the semi space copying collection process, large number of memory copying...
