Subtractive clustering and k-harmonic means clustering are two of the popular clustering algorithms. However, k-harmonic means need generate some initial centers for its initialization, and subtractive clustering do not need the initialization. Therefore, subtractive clustering often cannot gain the better clustering performance. In this paper, a novel subtractive clustering is proposed. The new method...
To better utilize the medical data in electronic medical records (EMR), this study aims to present an online adaptive method for disease prediction based on the medical data of clinical laboratory test (CLT) items stored in EMR. We firstly extract the diagnosis and CLT items information from the system, and then divide the CLT items into three categories to establish the patterns of CLT items, which...
This research proposes software reliability modeling method based on Failure Data, which is an improvement to the traditional software reliability modeling methods. And the same time, this paper also proposes corresponding verification method as to the research of software reliability model on software design defects and failures. Firstly, the failure data is collected in the software running process;...
This paper proposes an improved FP-Growth algorithm which modifies the support count to filter high confidence and high lift telecommunication network alarm big data. And to satisfy the big data environment, this paper improves the algorithm to be a distributed algorithm based on Spark. Experiments show that the improved FP-Growth algorithm mining strong association rules either in frequent patterns...
Computer technology is developing rapidly, the volume of logs in large internet companies witnesses an explosive growth. It is significant for the improvement of customer satisfaction and system stability to analyze and detect logs and timely find customer behaviors and the anomaly of system state. Aiming at massive log flow, TLSCA algorithm is first put forward based on sequence compression algorithm...
The image features play an important role in object detection and recognition, the method of object detection based on Histogram of Oriented Gradient(HOG) for its good detection result receives extensive attention to many researchers. This article describes the approaches to Histogram of Oriented Gradient and support vector machine, focusing on studying the HOG feature and application, detailing the...
Among all the applications and services currently used by the smart phone users, Instant messenger (IM) is the most actively used one, and deserves deep research of its service behavior properties. In this paper, we built an accurate traffic behavior model of the IM services, based on the huge amount of data that collected from the real smart phone users in the mobile network. Finally, an analysis...
The grate cooler is the main facility of the firing system, which operated mainly to cool and convey cement clinker, and provides hot air to rotary kiln at the same time. This paper analyzes the working principle of the grate cooler system and the main factors that affects the efficiency of the system. Through applying expert system and fuzzy control system in grate cooler, we can control and correct...
Affected by the stratosphere winds, the swing of high altitude platform station seriously affected the performance of the communication system. This paper described and analyzed the swing state of the platform, established the swing state of high altitude platform multi beam antenna coverage model. The expression of coverage geometry, received power and carrier interference ratio was derived. In the...
Most power information platforms are using IEC 61970 common information model (CIM) which has not focused on the on-line monitoring system at all. This is also the reason why each manufacturer produced its own productions and they usually have their own designing system. This situation has already become an obstacle for designing and implement the visual management system for power transmission and...
Based on the digital bit synchronization technology, Compared the characteristic QPSK demodulation and QAM demodulation of signals, To improve Gardner algorithm and use the Matlab simulation. Designed based on the Gardner algorithm 16QAM baseband signal bit synchronization, and used Modelsim simulation analysis, Demodution the improved algorithm to achieve the desired results.
The emergence of TV two-dimensional code not only makes the traditional TV media and new media to connect more closely, but also achieves the “mobile - television - network” direct interaction, greatly promoting the trend of media convergence. This paper, basing on the two-dimensional code generation techniques - PHP QR code, uses the MVC framework and Open API technology to design and complete the...
In order to solve existed accumulative error and SLAM problem for dead reckoning, this paper was proposed a positioning method combining with the known structured environment based on Extended Kalman Filter algorithm (EKF). This method quickly extracts the information of border and corner. According to the feature mapping relationships between world coordinate system and local coordinate system, calculate...
Parallel coordinates can visualize multidimensional data efficiently, during to its shortage in displaying time-varying data, we present a new method to add time dimension, which can extend parallel coordinates into 3D space(3D-Parallel Coordinates) consisted of attribute, range and time dimension. So that time-varying multidimensional data can be displayed as polygonal line cluster for recording...
Ontology database is a most comprehensive data base application that collects the related information from multiple data sources about any topic. Allowing multiple data sources into the database involves collection of irrelevant and redundant data. It leads to high memory utilization and more processing time. The user may be able to access the relevant data using appropriate software tools. In this...
With the rapid development of mobile smart phone and 4G network, online micro-video has come into the view of more and more people. The providers for the micro-videos hope that if they put their micro-video on a video website, they can get as much attention as possible. So it is becoming more and more meaningful to research the users' interest in different video websites. First of all, this system...
This paper uses a new face detection method based on Haar-Like feature. New Haar-Like feature is an extension of the Haar-Like feature basis. This article use four new Haar-Like feature, and these features with existing Haar-Like feature are input Adaboost classifier together to select feature, finally constructed classification performance and powerful cascade classifier for face detection. After...
Flow is one of the most fundamental physical process in natural world. Flow visualization can give an intuitive view of flow fields and contribute to the observation and analysis of flow. Really flow fields are all dynamic while traditional visualization approaches are not able to reflect the trends of flows or the diversity inside them. Based on the research of Lagrangian Coherent Structures in Computational...
Image restoration is one of the hot spots in the image vision research. Criminisi algorithm is a commonly used algorithm. In order to avoid the problem of inaccurate priority calculation caused by confidence dropping rapidly, and considering the variance difference between patches can reflect the image edge structure, we redefine the priority calculation. The fruit fly optimization algorithm is applied...
In this paper, we design a kind of magnetic compass sensor based on magnetic sense effect. The core of 3D magnetic sensor in each axis using Pomo alloy material molded to form a cylindrical core structure. Three axial magnetic core fixed on the polycarbonate plastic base is tightly matched with epoxy resin adhesive between the core and the base, which forms three-dimensional integration core structure...
