This paper proposed a new method of state of peak power capability prediction for Li-ion battery. Electrochemical impedance spectroscopy based equivalent circuit model is used as the reference model of battery dynamic characterization simulation, state of peak power capability is predicted based on the model and parameters estimation by fractional joint Kalman filter. By decomposing the voltage response...
This paper presents a CUDA-based real-time solution for true-color synthesis of remote sensing image. The solution reduces total execution time in three aspects. 1. Apply Pinned Memory to reduce data transfer time between host memory and GPU global memory. 2. Use look-up table to reduce computing time. 3 Overlap kernel executions and data transfers, besides register pages and execute kernels in parallel...
The number of mobile malware is greatly increasing and the malware detection malware has become a critical problem. Android is fast becoming the most popular mobile platform resulting in quick increase in malware targeting the platform. Current static-analysis practice on Android application package (APK) mainly uses the features such as signature, md5 hash, permissions, data flows, API (Application...
Depression is a common mental disorder and one of the main causes of disability worldwide. Lacking objective depressive disorder assessment methods is the key reason that many depressive patients can't be treated properly. Developments in affective sensing technology with a focus on acoustic features will potentially bring a change due to depressed patient's slow, hesitating, monotonous voice as remarkable...
Cloud computing industry is growing by leaps and bounds since businesses are increasingly moving its computing infrastructure to datacenters to take the advantage of economy of scale that cloud computing model offers. Like any other industry, cloud service sellers also face tough competitions from rival cloud service providers. Therefore, cloud service industry is also prone to customer churn where...
The problem of synchronization for master-slave chaotic system with coupling time-varying delay and sampled-data is researched in this paper. The time interval between two sampled processes is time-varying and the time interval is bounded. We used the input delay method to transform the sampled control system into a continuous system with time-varying delay. The synchronization criterion, which can...
In this paper, the de-noising method based on multivariate empirical mode decomposition (MEMD) is creatively proposed to put use to pulsar signal, filling the void that the previous methods based on the wavelet analysis have the limitations of choosing the basic functions, and the EMD algorithm's bounded that it can't process multiple signals jointly to avoid the mode mixing. MEMD is an extension...
Sentic Net is a popular resource for concept-level sentiment analysis. Because Sentic Net was created specifically for opinion mining in English language, however, its localization can be very laborious. In this work, a toolkit for creating non-English versions of Sentic Net in a time- and cost-effective way is proposed. This is achieved by exploiting online facilities such as Web dictionaries and...
Objective: This study aims to investigate the effect of Chinese herbs treatment of Kidney-strengthening therapy, Spleen-invigorating therapy and Liver-regulating therapy on monoamine neurotransmitters in ovariectomized female rats. Methods: 54 female rats were divided into six groups by random: control group, sham operation group, model group, Spleen-invigorating group, Kidney-strengthening group...
Data compression on sensing data in Wireless Sensor Networks (WSNs) has long been the topic of extensive research in the last decade. Especially, in video sensor networks, the video and image data that need to be transmitted are relatively larger than common data. However WSNs usually have limited power supply and constrained communication bandwidth, it is significant to reduce the video and image...
This paper presents a comparative study of five sorting methods for Lithium-ion batteries. The principle of each method and the feather of the sorting parameters are obviously described firstly. Then, optimized implement the experiment on LiFePO4/graphite cells. Sorting results are clearly analyzed subsequently. By analyzes the relationship among the parameters, there are strong correlation between...
Attribute-oriented induction (AOI) is one of the classical knowledge discovery methods for a relational database query in the field of data mining. On the basis of deeply analysis on the principles of the AOI method, this paper points out some problems existing in it such as redundant attributes after generalization and the invalid rules. This paper puts forward the concept of correlation degree with...
X-ray pulsar is an effective tool for navigation in deep space exploration. However, the noise contained in X-ray pulsar signal may severely decrease the accuracy of navigation system. This paper presents a signal denoising method based Empirical Mode Decomposition (EMD) method with thresholding method. For thresholding method, we propose a new adaptive thresholding method which can overcome the shortcomings...
Cyber-Physical Systems (CPS) involve communication, computation, and control through physical devices and computational components. The intrinsic heterogeneity, integration of computation and physical processes of CPS challenges the existing modeling frameworks. The close interactions between such systems and physical world make event-based approach as a remarkable solution for the modeling and simulation...
Rate-distortion optimization is widely used in modern video codecs to make various encoder decisions in order to optimize the trade-off between bit-rate and quality. The distortion models used in HEVC are mean squared error (MSE) and sum of absolute difference (SAD), both of which are not always reflective of perceptual quality. In this paper, we show that SSIM, which has been found to be a good indicator...
This article defines the innovation ability of urban agglomeration from the perspective of “input-output” and establishes the evaluation index system. The factor analysis and the system clustering analysis are adopted to study innovation ability in four emerging urban agglomerations. The four emerging urban agglomerations are located in the eastern, central and western China. The result shows that...
Wireless network has significantly affected human life. MAC protocols which already existed mostly transmit data without priority so that emergency event data cannot be sent quickly to destination nodes. In this paper, a new protocol called priority-and-activity-based QoS MAC (PAQMAC) protocol is proposed, in which not only the priority of data in transmission is considered, but also the active time...
Cyber-Physical Systems (CPS) involve communication, computation, and control through heterogeneous and widely distributed physical devices and computational components. The close interactions of these systems with the physical world make it difficult to model and simulate using traditional embedded system modeling and simulation technology. In this paper we address the main technical challenges on...
Crater detection is a very critical step in the deep space exploration and the edge of crater is the main information in an image. This paper proposes a wavelet transform method, which is to decompose a chosen B-spline function and then reconstruct the function to filter out the high-frequency segment. Finally, Calculate the max modulus value and angle of the gradient, and the set of the max value...
Many scholars have written about the impact of organizational justice on organizational citizenship behavior (OCB) of staff, while there are few researches discussing which dimension of OCB the three justice influence on hotel industry. Besides, servant leadership helps the leaders gain the employees' trust and reach high organizational performance. This paper also explores the influence of servant...
