In order to optimize aircraft performance and decrease operating and maintenance costs, traditional aircraft is moving towards a more electric aircraft. Moreover, integrated starting/generating system is one of the key components in a more electric aircraft. To determine whether starting/generating system meets the intended requirements, it is necessary to test the system. Herein, this paper is going...
Word2vec is a neural network language model which can convert words and phrases into a high-quality distributed vector (called word embedding) with semantic word relationships, so it offers a unique perspective to the text classification and other natural language processing (NLP) tasks. In this paper, we propose to combine improved tfidf algorithm and word embedding as a way to represent documents...
The purpose of this paper is to investigate the applicability of a relatively simple model which is based on energy conservation for model predictions as part of smart control of thermal and electric storage. The paper reviews commonly used predictive models. Model predictions of charging and discharging cycles are compared with experimental data of a domestic hot water thermal storage and lead acid...
A novel approach for generating multi-scroll chaotic attractor from a three-dimensional linear system is presented in this paper. (2N + 1) × (2M + 1)-grid scroll, (2N + 1)-scroll and (2M + 1)-scroll chaotic attractor can be formulated by an unstable three-dimensional linear system driven by two saturated function series. The new multi-scroll chaotic system is comprehensively analyzed based on its...
Focusing on behavioral corporate finance, we argue that personal characteristics of chief executive officers, in particular overconfidence, can account for the widespread distortion of overinvestment in China. Based on the data of Chinese listed companies from 2004-2008, we study the relationship between managerial overconfidence and corporate overinvestment. The main result is that managerial overconfidence...
Performance of DC/AC Inverters is decreased due to variable load parameters. Based on a voltage and current double closed-loop control inverter model, a novel load on-line parameter estimation control method is proposed. In this method, load parameters of inverters are calculated on-line. And then, controller coefficients of inverters are modified according to load parameters. Modify strategy of controller...
This paper analyses the impact of debt on corporate investment under the framework of duplicate soft budget constraint among the government, banks and firms in China. I find that in the corporate with low growth opportunity and high CFO, it shows significantly negative relationship between debt and investment in non-state-owned company. But in state-owned company it doesn't. There is a significantly...
By building simultaneous equations and using 333 Chinese manufacturing listed companies in the panel data from 2001 to 2007, the paper examines the relationship among debt financing, investment and corporate performance. The empirical results indicate that there exists a nonlinear inverse U shape relationship between capital structure and corporate performance, there also exists the same relationship...
Based on the cabin pressure regulating system characters of the nonlinear, larger inertia and time varying parameter, the arithmetic of fuzzy gain scheduling was proposed in this paper. The control parameters can be optimized globally using the controller based on the fuzzy gain scheduling because the fuzzy inference was used to changes the parameters of the controller online to adapt the change of...
Rotary eccentric loads often lead to vibration problems in motors, which may reduced their reliability and operating life. In order to reduce the radial vibration in permanent magnet motors, a real time detection method for rotary eccentric load based on the theoretical analysis of the motor vibration and the mechanical analysis was given, and a novel control strategy based on FOC (field oriented...
