The responsiveness of the GUI in an Android application is an important component of the user experience. Android guidelines recommend that potentially-expensive operations should not be performed in the GUI thread, but rather in separate threads. The responsiveness of existing code can be improved by introducing such asynchronous processing, either manually or automatically. One simple view is that...
Deformable objects such as garments are highly unstructured, making them difficult to recognize and manipulate. In this paper, we propose a novel method to teach a two-arm robot to efficiently track the states of a garment from an unknown state to a known state by iterative regrasping. The problem is formulated as a constrained weighted evaluation metric for evaluating the two desired grasping points...
Essential proteins are crucial to cellular survival and development. Traditionally, essential proteins are identified by knock-out experiments, which are expensive and often fatal to the target organisms. Regarding this, an important approach to essential protein identification is through computational prediction. In this research, we present a novel computational method, Integrated Edge Weights (IEW),...
Breast cancer is a leading cause of cancer-related deaths in women worldwide. Discovery of breast cancer-related disease genes is becoming very important to researcher and opens a new way to investigate pathogenic mechanism of breast cancer. Many studies have shown that the availability of human genome-wide protein-protein interactions (PPI) provides us with new opportunity for discovering disease-genes...
Human motion monitoring with inertial sensors plays an important role in many medical applications. But, acquiring robust inference of human motion trajectory via low-cost noisy inertial sensors remains challenging. Sensor noise and drift, sensor placement errors and variation of activity over the population all lead to the necessity of a large amount of data collection. In this paper, a new virtual...
Most dimensionality reduction methods are usually based on dissimilarity measurement of pixel intensities which can not obtain a more robust dissimilarity measurement. To address this problem, in this paper, we propose a novel robust dimensionality reduction method from Laplacian orientations. This method does not directly manipulate pixel intensity, which introduces Laplacian orientations, combined...
In this paper, we propose to use Bag-of-Words (BoW) model based methods for the remotely sensed images classification, and also attempt to do research about the image quality and algorithm evaluation. We introduce the Locality-constrained Linear Coding (LLC) for the remotely sensed image classification, and the hard vector quantization and soft vector quantization are adopted for experiments. Regards...
In this paper, we analyzed security and privacy problems of the current low-cost RFID system, and proposed a new RFID authentication protocol based on security policy. This protocol used these methods like setting tag information permissions according to fields and assigning tags with different privacy levels to prevent the authorized tag`s unauthorized information leakage and protected the user's...
This paper proposes a rail defect detection method based on vibration acceleration signals. The vibration signals are generated from the vehicle-track coupling model by inputting different typical rail defect excitations. The empirical mode decomposition method is used to decompose the signal. Intrinsic mode functions that have a big cross-correlation coefficient with the original signal are selected,...
RFID technologies are applied extensively in Cyber-Physical Systems (CPS). RFID system collects, filters, and integrates large volume of events gathered continuously by readers to process composite event detections from applications. When the system processes many composite events, detection sharing is quite important for their execution and enhancing the performance of the system. In this paper,...
Nonnegative Matrix Factorization (NMF), a popular compact data representation method, fails to discover the intrinsic geometrical structure of the data space. Graph regularized NMF (GrNMF) is proposed to avoid this limitation by regularizing NMF with a nearest neighbor graph constructed from the input data feature space. However using the original feature space directly is not appropriate because...
Through analysis the wireless network testing system of China Mobile Multimedia Broadcasting(CMMB) system and data mining association rules, design a method for analysis the CMMB wireless network. First, we can get a large number of data from wireless network testing system, and then, the data is discretized and import in database. Second, use the data mining association rules to obtain the key indicators...
Pornography identify platform based on SOA is posed, and structure figure and flow figure of the platform are given. Then the technology of ORDBMS (Object Relation Data Base Management System) is focused on, and the merit of ORDBMS in Pornography platform is discussed. In the application of ORDBMS in Pornography platform, object-oriented data model of platform is firstly constructed, then giving the...
The problem of Optimal Path Analysis is an important content of spatial analysis in GIS. Based on the classical shortest path algorithm -Dijkstra and the Network Model of ArcGIS Geodatabase, the Optimal Path Analysis is realized by using redevelop function of ArcEngine. Practicality and reliability of the method is verified in Zibo Fire Emergency Management Information System Construction.
As a complementary and alternative system to Western medicine, traditional Chinese medicine (TCM) forms an integrated and unique approach to treat diseases. In response to the subjectivity and fuzziness of TCM, quantitative methods are needed. In TCM, the symptoms are often high dimensional and the redundant and irrelevant symptoms may degrade the performance of classifiers. Therefore, a critical...
J2EE-based Web applications are becoming increasingly ubiquitous and with their increasing adoption, the performance is the attention focus and the most important factor of evaluating the system by users. In this paper, we present a systematic solution for performance testing and optimization of J2EE-based Web applications. The solution helps to identify and eliminate bottlenecks in the application...
Pro/TOOLKIT and FamilyTable provided by Pro/ENGINEER and Visual C++6.0 are utilized to develop three-dimensional standard part library of riveting joint according to national riveting joint standards. Feature based modeling and FamilyTable are used to construct three-dimensional riveting joint part library. The interface between Pro/ENGINEER and MFC is developed using DLLs to establish a man-machine...
Crawling deep web is the process of collecting data from search interfaces by issuing queries. With wide availability of programmable interface encoded in Web services, deep web crawling has received a large variety of applications. One of the major challenges crawling deep web is the selection of the queries so that most of the data can be retrieved at a low cost. We propose a general method in this...
In this work, we record a dancer's rhythmic movement with background music. The captured motion sequences are then segmented into dozens of motion clips, to construct a motion database consisting of sets of labeled motion clips. Many of these motion clips contain short and rapid transition from one main dancing motion to another, which causes unnatural, awkward movements when they are connected in...
