Lithium Ion batteries usually degrade to an unacceptable capacity level after hundreds or even thousands of cycles. The continuously observed capacity fade data over time and their internal structure can be informative for constructing capacity fade models. This paper applies a mean-covariance decomposition modeling method to analyze the capacity fade data. The proposed approach directly examines...
The convergence analysis of the affine projection algorithm (APA) was intensively studied, however, it is far to be a trivial task. In this context, a set of assumptions have to be considered, in order to allow a tractable analytical approach. As a consequence, notable differences occur between the simulation results and the analytical model. In this paper, the convergence of APA is studied and a...
Astronautically Phased Mission System (APMS) has the characteristics of sophisticated system structure, complex mission profile and varied system working modes and states. For these characteristics, this paper analyses the mission profile and reliability features (sequential, correlate and dynamic) of APMS, and proposes a method of reliability synthetic modeling considering multi-feature for APMS...
In aircraft type certification, simulation system is used for airworthiness demonstration in lieu of real flight test in certain scenarios, and credit needs to be taken for the simulation system to validate it is capable of representing the characteristics of the airplane under certification. The general requirement and approaches for simulation credit taken is discussed. Typical simulation tasks...
Different kinds of maintenance events in practical maintenance have different effects on equipment operation and task success. Based on the characteristics of multiple events and uncertainties of maintenance events, this paper analyzes the influence of various maintenance events on maintenance cost decision under different maintenance times, and determines the influencing factors of maintenance cost...
All industries are affected by finance factors and the first factor to evaluate the development of a country must be its financial resource in which the banking sector development plays a significant role. The bank is seen as the lifeblood of an economy, an intermediary activity associated with the movement of the entire economy and covering all socio-economic activities. The research calculates the...
Recent low-rank based matrix/tensor recovery methods have been widely explored in multispectral images (MSI) denoising. These methods, however, ignore the difference of the intrinsic structure correlation along spatial sparsity, spectral correlation and non-local self-similarity mode. In this paper, we go further by giving a detailed analysis about the rank properties both in matrix and tensor cases,...
There has been incredible growth of events over the internet in recent years. Google has become the giant source of knowledge for any event which has happened or happening over the internet. Some networking sites such as face book, micro blogging sites such as twitter are evolved with time and became the highly used sites over the internet. Various E-commerce websites such as Amazon, Ebay, Flipkart...
Based on the traffic accident data of Beijing China in 2012, we combined with a variety of municipal administration data, used the geographically weighted regression (GWR) method to study spatial non-stationarity and heterogeneity of the traffic accidents, and analyzed the causes of space regional in traffic accident black spots. Experimental results demonstrated that: (1) The GWR model detects change...
With the requirements of antenna pointing accuracy increasing, the high frequency flexible characteristics have become the important factor of limiting the control performance for antenna servo systems. In this paper, an identification method is given to identify the mobile satcom antenna (MSCA) servo system with flexible structure. Using PRBS as the input signal, the impulse response is acquired...
Tracking-by-detection has become a popular tracking paradigm in recent years. Due to the fact that detections within this framework are regarded as points in the tracking process, it brings data association ambiguities, especially in crowded scenarios. To cope with this issue, we extended the multiple hypothesis tracking approach by incorporating a novel enhancing detection model that included detection-scene...
Because of the characteristics of the availability and practicability, mobile media technology had got a rapid development in the whole world. So, people now often use mobile devices through a mobile application (APP). Based on this, this study established a mobile application customer engagement model to carry on the investigation and research about mobile application of customers' recommendation...
With the demand of power information construction and the application of D5000 platform, the standardization and management of all kinds of data becomes a necessary condition for data sharing and application integration between systems. In order to realize the safe, convenient and efficient information resource sharing of power enterprises and improve the information management level, the fusion method...
Products arranged in the same zone usually have some spatial correlation, function relation and the impact of environmental stress, which usually causes coupling effect with other products in the same zone. This kind of coupling effect affects products' quality, and may influence the veracity and comprehensiveness of the quality analysis. To solve this issue, starting from changing the traditional...
Fault localization defines information models from raw runtime information as the input, depicting program behaviors for supporting localization algorithms. It is natural that an elaborate information model is desirable and likely to improve the effectiveness of fault localization, because it typically depicts subtle and more program runtime behaviors. In fact, much work on fault localization assumes...
Wind power short-term power prediction is an important index to evaluate the level of wind power operation, and it is also an important parameter to guide the safe operation of power system. Considering the singleness one-sidedness of the existing evaluation index, this paper aims to construct a comprehensive evaluation index system for regional wind power forecasting. The traditional single evaluation...
Despite the crucial importance of metamodeling for Model-Driven Engineering (MDE), there is still little discussion about the quality of metamodel design and its consequences in model-driven development processes. Presumably, the quality of metamodel design strongly affects the models and transformations that conform to these metamodels. However, so far surprisingly few work has been done to validate...
In conventional cellular networks, for base stations (BSs) that are deployed far away from each other, it is general to assume them to be mutually independent. Nevertheless, after long-term evolution of cellular networks in various generations, the assumption no longer holds. Instead, the BSs, which seem to be gradually deployed by operators in a casual manner, have embedded many fundamental features...
A general analytical framework based on generalized mutual information is applied to the analysis of massive multiple-input-multiple-output systems with low-resolution output quantization. For Gaussian codebook ensemble and nearestneighbor decoding rule, an equivalence relationship is established for general nonlinear transceiver distortion, that the effective signal-to-noise ratio based on the generalized...
Proliferation of mobile digital devices has posed major challenges for design and implementation of Wireless Local Area Networks (WLANs), leading to stringent quality of service (QoS) requirements. Extreme burstiness and correlation characteristics of multimedia traffics generated by digital devices require accurate modelling and analysis to provide satisfactory end user experience. Most existing...
