In order to solve the problem of ECG signal detection, wireless sensor network is designed with ZigBee technology. This article describes the details of the system structure, the design of hardware and software and the communication methods. we can realize wireless detection of human ECG signal through the wireless sensor system. Design the host computer software system based on Qt framework can achieve...
In the open source community such as GitHub, developers usually need to find projects similar to their work, with the aim to reuse their functions and explore ideas of features that could be possibly added into their project at hand. Traditional text search engine can help detect similar resources. However, it is difficult for developers to use in open source community because a few query words cannot...
This paper proposed to utilize bug knowledge graph for bug resolution. Bug knowledge graph provide more comprehensive and relevant bug information (i.e., bug reports, commits, relevant developers, etc.). Moreover, our approach can automatically update bug knowledge graph based on the the lifelong learning topic model. Preliminary results show that bug knowledge graph can provide more accurate and...
Aiming at the problem that the existing GPRS monitoring system has no signal in some areas and the expensive price, an on-line monitoring system for transmission line based on 6LoWPAN technology is proposed. 6LoWPAN technology has built a bridge for communication between the wireless sensor and the Internet for the system, and achieved data collection, analysis to the transmission line temperature,...
The technique presented in this paper concerns the problem of how to automatically obtaining the specification of the resulting set of reachable nodes, after destructive operations over the data structure. Our work has two main contributions. First, we represent the node sets by expressions at pre-states, which facilitates the process of proving complex formulas efficiently. Second, we propose an...
As the high energy particles generated by laser-plasma interaction are widely used in laser fusion, accelerators, and medic al applications and so on, modeling and simulation technique s have been playing a more and more important role in research of laser-plasma interactions.
A 1/3D nonlinear beam wave interaction (BWI) model for klystron has been put forward, in which the equations take z as independent variable. The particle's motion can be easily processed for fixed axial step, and the induced current is derived from the energy translation from all of the particle's modulation by the fields. The software has been developed with a friendly user interface and powerful...
This paper presents a Quantization Parameter (QP) refinement algorithm used in Rate-Distortion Optimization (RDO) process to improve the coding efficiency for High Efficiency Video Coding (HEVC). To minimize the RD cost, QP is one of the parameters that can be optimized. Usually, multiple-QP optimization can be applied to choose the best QP value. However, this kind of optimization increases the encoding...
For great change of service time for request, big difference of hardware and software server and different network performance, this paper proposes a dynamic-feedback algorithm based on AHP in the course of studying the algorithm of load balancing in the cluster-based system. Combined with Weighted scheduling algorithm of the kernel, based on the parameters influencing the performance of cluster system...
In allusion to the problem of fragmentary annotation in some GIS software, the author points out one new method: connection of annotation and geographical object. Taking the dynamic annotation of curve for example, the author discusses its process in detail, which is applied to the development of our own GIS software.
This paper presents the results of compression comparison tests between the current state of the emerging High Efficiency Video Coding (HEVC) draft standard and the current dominant standard H.264/MPEG-4 AVC (High Profile) as an anchor reference. The conditions used for the comparison tests were designed to reflect relevant application scenarios and to enable a fair comparison to the maximum extent...
Every language has its own culture background, thus it is difficult to translate or retrieve figurative expressions across languages. Based on the metaphoric cognition and feature analysis theory, we collect data from the web to construct the Chinese-English bilingual lexical cognitive property knowledgebase linked to "HowNet". By comparing the differences of the cognitive property, we get...
As semiconductor technology scales into deep submicron regime, transient fault vulnerability of both combinational logic and sequential logic increase rapidly. It is predicted that in 2011 transient fault rate of combinational logic will overtake that of sequential logic in processor. In this paper, particle radiation-induced multi-bit transient faults in decoder unit, representative combinational...
From the model established, running and the data post-processing, the operation of GT POWER is in GT-ISE and the method is simple and efficient. In order to solve the problem of reducing repeat - work in GT-POWER operation, intuitively correspond and alter of the model parameter also and the secondary development of software and modularization of background of software development which is accord...
The control of a snake-like robot is a challenging problem because of unknown environments and complex dynamics. We have proposed an energy-based method, called passive creeping, to control the serpentine locomotion. In the paper, we present a hypothesis that the energy state of the robot can influence the locomotor adaptation. And then we lay emphasis on experiments in order to test the hypothesis...
The paper illustrates the necessity and development prospect of EP-ERP system application in electricity generating enterprises by analyzing significance of information-based construction. The conception of establishing EP-ERP system model in management of electricity generating enterprises, aiming at the current situation of information-based construction in electricity generating enterprises, is...
Practical education of biostatistics is an important way of changing abstract theories into lively and operable methods. There are many problems in practical education of biostatistics in Colleges. How to reform the practical education of biostatistics is very important for improving students' quality. In this paper, a survey with stratified sampling was taken to investigate the way of practice, tools...
One design goal of future processors is to maximize the performance per watt. However, the performance of general purpose processors can be hardly improved by barely increasing clock frequency. This paper presents an application specific reconfigurable processor architecture which is fine tuned for high performance computing. It benefits from the application specific hardware customized to significantly...
13 lines including 9 wheat mutants of genetic transformation by ion beam and 4 acceptor control varieties were analyzed by SSR marker. A special band of dwarf mutant line 1042 was obtained, sequenced and analyzed by blast software. The genetic distance was analyzed with SSR marker materials by SAS software. The result showed that 9 wheat mutants were clustered together with their own acceptor control...
Both Geographic Information System (GIS) and decision support system (DSS) are playing an important part in government affairs management or electronic government (E-government). But GIS and DSS are usually independently working the interactive relation between them is unsubstantial, so that application of E-government to GIS is inconvenient and inefficient. This paper puts forward a new idea for...
