Developing simple and effective algorithms for detecting cardiovascular diseases (CVDs) using smartphones has been the trend of research in pervasive healthcare. This paper proposes an efficient R-wave detection algorithm and tested it in an Android Smartphone. We use the complete datasets of MIT-BIH arrhythmia database to verify its relative performance with three other algorithms. Our results show...
In order to deal with the limitation of the unmoral biometric systems, a multimodality emotion recognition system is proposed based on kernel canonical correlation analysis (KCCA). Because audio signal and facial expressions are two main channels of emotional communication, this approach extracts prosodic features and the visual features in FrFT domain. Those features are fused for the emotion recognition...
This paper presents a device used in a new type of EDM CNC machining pulse power, a detailed analysis of each functional module design ideas and conducted experiments related to power, the experimental results show that the pulsed power supply stable and reliable operation, the processing efficiency is higher and achieves the desired design goals.
Computer image processing technology is mainly to research how to use the computer to complete the basic theories and methods of image information processing. At present, in medical diagnosis, industrial automation detection, intelligent robot, traffic, communication, geology and other fields, the computer image processing technology has been widely used. This paper proposes a novel shape recognition...
Introduce a design of transmission priority TFT-LCD controller IP core based on Programmable Gate Array. And a case for controlling LCD named SHARP LQ104V1DG52 by CPLD for ARM interface is proposed. Practices prove that the controller operates well.
The electronic commerce develops rapidly today and amount of information of commodity supply and demand in Internet put forward higher requirements for traditional search engines. The question of how can find the required commodity supply and demand information rapidly and exactly, and avoid retrieval overstretch of the general search engine information makes e-commerce search engine oriented gradually...
The so-called cloud computing refers to real-time service of network technology provided by internet, taking the computer as carrier and based on network. It is a kind of targeted service that provides users what they need and charges fee according to the volume of user's, which greatly improves the rate of resource-sharing. The technology now has been quite mature. Cloud computing with powerful information...
The scheme determination of industrial boiler is an iterative process, a lot of work. Conduit system diagram, is the “skeleton” industrial boiler scheme design, as shown in figure 1 the main diagram, so it “finalize” is especially important. Parametric ideas proposed in this paper is mainly for processing design, software development, the first task is to study different design scheme, break it down...
Network security situation awareness is a comprehensive technology which can obtain and process the information of security, and it plays an important role in the field of network security. As the traditional network security situation awareness methods mainly forecast the situation value based on mathematical models, which will result in the ignorance of the dynamic changes of network security situation...
Because of the complexity of Chinese farmers income forecast and BP neural network's ability to handle complex problem and auto-adaptive ability, the application of BP neural network in Chinese farmers income forecast is necessary and feasible. This paper establishs Chinese farmers income forecast index system, introduces neural network and gives the realization and optimization of BP neural network...
Domain ontology in military transportation is applied to information retrieval to create corresponding personalized user interest models and personalized information retrieval model, construct a knowledge base on basis of domain ontology in military transportation, in order to to improve the efficiency in information retrieval and to provide users with timely, accurate and high-quality personalized...
A 3-D finite elements model for a type of thermoelectric generator (TEG) with cylindrical shell and straight fins is established in this paper. This model is simulated in ANSYS Workbench and CFX environment. Results show that increasing the inlet temperature and the inlet velocity of exhaust flow, as well as reducing the inlet temperature of coolant flow can improve the output power of TEM. Changing...
The paper introduces a kind of wireless mine hydrology monitoring system based on Labview Upper monitor interface to face with some disadvantages such as the fast changing of mine hydrology, the large number of informative data on monitoring, remote location and harsh environment. The system uses the sensor to collect automatically the information of the mine on water level, water temperature, water...
Based on Gaussian mixture model and background difference, a novel moving object region detection method is presented for static camera surveillance. First of all, the adaptive threshold is used to get background difference image. Secondly, by analyzing the connected domain and setting a threshold, the influence of the noise in the difference image is eliminated and the moving object regions are determined...
The development of internet technology has made great impacts on our daily lives. Since the world has gone through the changes of industrial economy to knowledge economy and internet knowledge explosion, the centers of enterprise operations have also been switched from real property assets to intangible assets and consumer anticipations. This research was aimed to base on the studies on the relations...
For the convenience and optimization, IBCS is brought to the whole process of industrial boiler design. According to the characteristics of the industrial boiler design, the ideas of intelligentized design are put forward, but also the concrete implementation approach and the implementation method, the contract methods and ways of each module, are also elaborated. At the same time the overall structure...
For recent years, attribute-based trust management has become the key factors for enterprises' operational performances. To cope with the trend of internationalization and global competitions, the enhancement of attribute-based trust management has turned into the real estate industry's priority to enhance their competitive advantages. Nowadays, house buyers that are familiar with particular regions...
Through analysis of the literature discuss the development of electronic whiteboard in detail, and proposes the implementation strategy for electronic whiteboard training activities. Expect to realize the application of using electronic whiteboard, accelerate the development of electronic whiteboard, improve training efficiency.
Based on the principles of Langmuir probe for plasma diagnosis, we analyzed the working principle of single Langmuir probe. We connected the scan power supply to the probe, when the probe comes to the electronic saturated current. Since the probe current is very big, then it will lead to serious probe fever and further its resistance value will increase, finally this will result in the measured parameters...
The aim of this study was to evaluate the role of computer tomography (CT) in the judgment of location and etiology of acute mechanical intestinal obstruction(AMIO). Sixty-four patients with AMIO were retrospectively reviewed. Two experienced radiologists retrospectively analyzed the CT and X-ray films by double blind method. The evaluation results of ultrasonography examination were from the original...
