Normally, the gait of each person has individual style so it can be used for human identification. In this paper, the gait recognition using shape trace transform is presented for human identification. First step, gait recognition using shape trace transform used the silhouettes input. The gait period could be estimated by computing the median of the walking step width of the three consecutive maxima...
The human brain undergoes many age-related changes, such as the atrophy of brain volume, the thinner of cortical thickness, the loose of white matter and so on. Here we aimed to explore whether the covariance existed among the regional gray matter volume with aging. 169 brain magnetic resonance images (MRI) of healthy people (54 males and 115 females, 18 to 92 years) were selected from OASIS database...
Cloud computing is defined as a pool of virtualized computer resources. Based on this Virtualization the Cloud Computing paradigm allows workloads to be deployed and scaled-out quickly through the rapid provisioning of VMs or physical machines. A Cloud Computing platform supports redundant, self-recovering, highly scalable programming models that allow workloads to recover from many inevitable hardware/software...
Cancer classification of gene expression data helps determine appropriate treatment and prognosis. Its accurate prediction to the type or size of tumors relies on adopting powerful and efficient classification models such that patients can be provided with better treatment. As a graph-based method for linear dimensionality reduction, Locality Preserving Projections(LPP) searches for an embedding space...
Considering that the baselines of scores are often different in various classes or course groups, standard score is used to denote as evaluation foundation avoiding subjectivity of the conventional teaching evaluation methods. And then, we cluster the evaluation matrix into specified-number clusters using FCM. Experimental results have verified the effectiveness and rationality of the proposed methods.
This paper proposes an automatic method of detection of facial features - eyes and mouth, based on color and on the symmetry map. The improvement of the quality of the image and the application of the correction techniques, such as the re-escalation of the image, the ellipsoidal vignetting or related processing lead to a detection rate of the facial features of up to 82.21%, as compared to 56.18%...
Computer-assisted instruction(CAI) plays important roll in morden medical education. We experience that CAI has many innate advantages in medical immunology class teaching over traditional education and some problems due to improper application. CAI needs to be popularized vigorously, but traditional teaching model can't be displaced completely. Both of them are compatible, and have complementary...
Resource allocation problem in universities belongs to office automation research issues, which is one of the important businesses for management departments in universities. Aiming at “Just, Fair and Open” principle and purpose of user-oriented resource management, rational allocation by means of informatization and efficient use of resources is certainly an effective way. In this paper, we study...
In this paper, a hybrid approach incorporating genetic algorithm and rough set theory into Feature Selection is proposed for searching for the best subset of optimal features. The approach utilizes K-means clustering for partitioning attribute values, the rough set-based approach for reducing redundant data, and the genetic algorithm for searching for the best subset of features. A set of six attributes...
The traditional electronic medical records storage pattern has became the bottleneck of its rapid development, this paper introduce the cloud storage mechanism for electronic medical records, HBase is a distributed column-oriented database built on top of Hadoop Distributed File System based on the common computer cluster. After researched on the distribution storage mechanism of Hadoop Distributed...
This paper concentrated on how to apply meshless method to do physical based soft tissue deformation. First we approximated the deformation field using a Moving Least Squares (MLS) approximation method. Then, a compact force computation was applied to accelerate the physical computation speed. Finally we implemented a surface animation method to simulate the deformation of soft tissue under external...
This article describes a variety of FPGA-based radar signal generator. This system is connected to the host, binding data from the software interface, through the PCI bus transfer stored in the system. Within the FPGA to achieve DDS signal generator, and finally through the digital-analog converter output. Finally, the system resource utilization and the actual results are given.
To reform experiment teaching on microbiology of TCM specialty, the focus of reform is strengthen targeted and practicality of experiment teaching, increase contents about relationship of TCM and microbiology, etc. in experiment teaching; increase experimental contents on comprehensive application; improve assessment methods of experimental classes. Make teaching contents accord with the training...
Emerging technologies, to a large extent, have become driver of economic development in a region and even a nation, so to grasp the economic impact of emerging technologies is of significant meaning. This paper set out from the connotation of emerging technologies, then discussed the economic effect of emerging technologies respectively from their evaluation content and evaluation methods. Based on...
Aiming at diagnosing and preventing the cardiovascular disease, a portable ECG monitoring system based on Bluetooth mobile phones is presented. The system consists of some novel dry skin electrodes, an ECG monitoring circuit and a smart phone. The weak ECG signals extracted from the dry electrode can be amplified, band-pass filtered, analog-digital converted and so on. Finally it is sent to the mobile...
The purpose of the experiment: to explore the primary cultural method of vascular endothelial cell in rat that we have got through obtained and cultivated, the experiment were provided to the corresp technique of the further research. Experimental methods: the aorta of Wistar rat was obtained in operating microscope, then removal the adventitia and adipose tissue. The blood vessel were sheared like...
Using the previous studies on educational game development and coercive learning as our basis, the goal of our project is to be able to develop video games for mobile handheld devices that will be used as educational tools for the topics in the Grade 6 Science Curriculum. The game that we developed tackled Food Chains and Food Webs as topics which are parts of Grade 6 Science Curriculum. The game...
Purpose: The purpose of this study was to study the extract of Rumex root which had an inhibitory action on the cell proliferation of human leukemia cell line THP-1. Methods: The combination of percolation and extraction was used to separate and extract the main chemical compositions of Rumex, MIT was used to assay the curve of inhibition ratio. Results: The petroleum ether and acetone extracted from...
This paper focuses on the use of a discrete simulation tool ( Simio ) to explore simulation of casualty treatment in wartime. Through the use of Simio simulation platform, visual simulation model of casualty treatment was developed, based on analysis of the casualty treatment task and process in wartime. Then, a personnel allocation in an operating room was tested using the model developed by simulation...
Web-based autonomous language learning system enjoys great popularity among college English learners in China. It provides abundant educational resources for the learner. Efficient use of available materials on the system needs intelligent resources recommendation and personalized guidance in learning strategies. This paper uses the data mining technology to build an automatic recommendation agent...
