Nowadays, light emitting diode (LED) lamps have been widely utilized for lighting system due to its low-energy consumption. The harmonic emission standard is ignored by most of the manufacturers, high current will increase injection and cause fire risk. Existing research focuses on investigating emissions from several specific LED drivers, but a systematic evaluation approach not given. contrib...
This paper describes the topic-based Chinese message polarity classification system submitted by LCYS_TEAM at SIGHAN8-Task2. The system mainly includes two parts: 1) a graph-based ranking model integrating local and global information is adopted to represent the classification ability of words towards different topics. In construction of graph model, a new weighting approach and a PMI-based ran...
We describe the problem of decision making under ignorance and discuss the need of introducing a decision attitude or disposition in solving this problem. We show the OWA operators provide a general framework for evaluating the alternatives when the payoffs are numeric values. We then turn to the problem of decision making when the payoffs are linguistic values drawn from an ordinal scale. A so...
application of automatic systems, including discharge measurement technology is one of the effective methods for improving delivery management, water use efficiency, flexibility, and performance of irrigation networks. several aspects such as hydraulic, technical, physical, environmental, economic, social, and managerial, have significant impact on these systems selection. due to diversity of t...
Reliability allocation is one of the most important factors to consider when determining the reliability and competitiveness of a product. The feasibility-of-objectives (FOO) technique has become the current standard for assessing reliability designs for military mechanical–electrical systems, whereas the average weighting allocation method is widely used for commercial applications. However, a...
Focusing on the complexity of structure and diversification indicators in equipment support information system, a combination weighting method was proposed to evaluate system effectiveness. Firstly, based working principle this constructed its evaluation indicator system; Secondly, subjective objective characteristics indicators, it determined weight each by combining entropy G1 sequence method...
The articles [17], [18], [3], [5], [4], [8], [2], [7], [11], [6], [16], [12], [19], [9], [10], [1], [14], [15], and [13] provide the notation and terminology for this paper. For simplicity, we use the following convention: k, n, m denote elements of N, X denotes a set, s1, s2 denote complex sequences, Y denotes a subset of C, f , f1, f2 denote partial functions from C to C, r denotes a real num...
The goal of clustering is to identify common structures in a data set by forming groups homogeneous objects. observed characteristics many economic time series motivated the development classes distributions that can accommodate properties, such as heavy tails and skewness. Thanks its flexibility, skewed exponential power distribution (also called generalized error distribution) ensures unified...
The mechanical fault diagnosis of a disconnector operating mechanism using single signal is not sufficiently accurate and reliable. To address this problem, paper proposes new method based on the vibration motor current signal. First, analysis stator envelope, segmented envelope RMS values are extracted. Then, processed with VMD (Variational Mode Decomposition). In paper, number modal decomposi...
