The precise integration method is a semi analytical solution method of partial differential equation method. Based on the precise integration method, the lossy transmission line transient response analysis method is a time domain analysis method. The lossy transmission line transient response analysis method can easily deal with the transmission line problems, which is difficult for the nonzero initial value and nonlinear load frequency domain method to deal with, but it is still difficult to deal with the reactance load of transmission line. By separating and integrating the beginning and terminal conditions of the precise integration method, and introducing time domain adjoint model of the various kinds of load, this paper solves the problems of the load reactance of transmission line, also solves the transmission line problems of long time transition, short circuit and open circuit, which greatly improves the precise integration method for the analysis of the efficacy of transmission lines in time domain response. Finally, the correctness of the presented method is illustrated by the application examples, which provide a theoretical basis for the time domain analysis of the transient response of the transmission line.

Blur plays an key part in evaluating of camera image quality. It leads to decrease of high frequency information and accordingly changes the image energy. Recent researches in quaternion singular value decomposition show that the quaternion's singular values and associated vectors can capture the distortion of color images, and thus singular values can be utilized to assess the sharpness of camera image. Based on this, a novel blind quality assessment method considering the integral color information and singular values of the blurred camera image is proposed for evaluating the sharpness of camera image. Pure quaternion is utilized to represent pixels of the blurred camera image and the energy of every block are obtained. Results confirm the superiority of the proposed blind algorithm in assessing camera images.

Signal peptides are significant important in targeting the translocation of integral membrane proteins and secretory proteins. Due the high similarity between the transmembrane helices and signal peptides, classifiers have limit ability to discriminate the signal peptides from the transmembrane helices. To solve this problem, the protein functional domain information is applied in this method. For accurately identify the cleavage sites along the sequence, a subset of potential cleavage sites was firstly screened out by statistical machine learning rules, and then the final unique site was picked out according to its evolution conservation score. This method has been benchmarked on multiple datasets and the experimental results have shown its superiority.

The purposes of this paper are to calculate exactly the mean thickness, plot the thickness maps, and depict the early treatment diabetic retinopathy study (ETDRS) charts for ten intra-retinal layers by spectral domain optical coherence tomography(OCT). Using our previously the reported segmented method with a simple linear iterative clustering (SLIC) super-pixels and manifold ranking (SLIC_MR), the ten intra-retinal layers were fast and exactly segmented in 3-D OCT dataset, includes 55 B-scan images from 11 different healthy adult subjects. By our definitions of the sensitivity and specificity, we compared the segmented results with the recent graph-based method for the main layers in dataset. The experimental results demonstrated that the SLIC_MR method outperformed the graph-based method. The thickness maps were plotted in the ten intra-retinal layers and the overall layer, the ETDRS charts were depicted in the 9 sectors of each intra-retinal layer and the overall layer, and the bar graph displayed the mean and standard deviation of macular thickness in 9 sectors for ten retinal layers and the overall layer. The mean thickness of the central foveal area displayed the minimum thickness in layers 1, 2, 3, 4, 5 and the overall, and the maximum thickness in the central foveal area of the 6th layer. Both layers 4 and 5 have the similar mean thickness in each sector.

A novel method for fault location is proposed in this paper, which is based on fault voltages and currents sampled synchronously on both ends of the fault line. This algorithm is based on precise integration. Using the synchronous measurement data at the ends of the fault line, it computes the voltage along transmission line. Then comparing two groups of voltage, it can find out the location of trouble spot. This method has the advantages of quick calculating speed and accurate calculating results. Both theoretical analysis and simulation results justify the feasibility of the algorithms above.

Erectile dysfunction (ED) is a frequent disorder in aging men, affecting men's physical and mental health seriously. Generally, clinical diagnosis of the physical ED need image of penile vessels to distinguish vasculogenic ED disorders from psychological disorders so as to determine an appropriate treatment. The aim of this study is to present a novel photoacoustic microscopy (PAM) for imaging of vasculogenic ED with a high resolution and a high sensitivity. In this work, a vessel phantom using a carbon pencil and ten animals' penis models isolated from health rats both were prepared carefully. A home-made PAM platform was builted for rat's penile vessels, and the corresponding two dimensional (2D) PAM image was obtained for each model. Particularly, an imaging capability of a high spatial resolution of five hundreds microns with high contrast was obtained. The preliminary imaging results of isolated penis vessel clearly indicated that the method of photoacoustic imaging would be a useful diagnostic tool for assessing vasculogenic ED and could improve the diagnosis of venous leakage visualization by combining structural and functional imaging.

In many fields of MRI (Magnetic Resonance Imaging), especially in DMRI (Dynamic MRI) domain, long acquisition time often limits its clinical applications. The new online MRI technique can obviously accelerate the imaging time for DMRI based on under-sampling acquisition and sparsity performance between neighbor frames. The data acquisition of previous online MRI schemes was based on the Cartesian coordinate. Non-Cartesian sampling, such as radial sampling, can obtain higher data acquisition speed than conventional Cartesian sampling. In order to further accelerate the imaging speed for online MRI, radial under-sampling instead of Cartesian under-sampling, was proposed to shorten the data acquisition time for DMRI. However the reconstruction of non-Cartesian data is complicated and time consumed, so GPU (Graphics Processing Unit) was used to shorten the reconstruction time. In this primary study, the full sampled cardiac dataset was used as a reference dataset, radial under-sampling with 25% and 10% k-space coverage was simulated for the online imaging scheme. The results show that radial under-sampling scheme obtained higher image quality than that of Cartesian acquisition scheme, with its imaging time still satisfying online reconstruction after applying GPU acceleration.

Nowadays, mobile devices, virtual reality and augment reality technologies are developing faster and faster. With a variety of equipments, people are no longer only using PC to handle tasks. Some traditional system frameworks are migrating to these new technology areas, and direct volume rendering is one of them. In this paper, we propose a real-time and intuitive volume data exploration framework on mobile devices. Our framework introduces a direct-touch transfer function design method that is able for the user to pick voxels directly on a volume rendered image. With one-pass shader, user interaction and volume rendering can be handled efficiently in real-time. The user only needs to learn a few related knowledge to explore a volume data and get its rendered image. As a result, the time cost of transfer function design for direct volume rendering is significantly reduced. Our framework is implemented with OpenGL ES 3.0 and GLSL shader. Experimental results show the advantages of our framework. Researchers, and even general users, can easily obtain volume rendered images of volume data.

A video monitoring system in construction site will produce a large number of video images, which influences safety production supervision personnel to find unsafe behaviors. This paper presents application of intelligent behavior identify technique. Based on this technique, the video monitoring system can capture video streaming data, exquisite frame image data, and identify of the image data by analyzing the video camera. The detection behaviors include: 1) Does there exist any moving object in designated areas? 2) Does every worker wear a safe helmet in construction site? If there is one or more of the above detection information in the current frame image, the video monitoring system will give tips in the human-machine interface, and adopt a variety of ways to deal with the corresponding information. From the implementation effect, this system meets the requirements on accuracy and efficiency.
