Over-development of fictitious economy may produce bubble capital and bubble burst can induce financial crisis. The Granger cause of the representative variable of real economy to the variables of fictitious economy in China is tested and the bubble expansion rate of each period of China's fictitious economy is calculated by the quarterly data from the second quarter of 1998 to the forth quarter of...
In this paper, a series of 2-amino-5-alkyl-1, 3, 4-thiadiazole zineb were prepared by reacting 2-amino-5-alkyl-1, 3, 4-thiadiazole, CS 2 and ZnCl 2 . Its synthesis conditions was discussed. The optimal conditions were obtained as follows: reaction time 120min, reaction temperature 30°C, molar ratio n (thiadiazole): n (zinc chloride): n (CS 2 ): n (NaOH) = 1:1:1.05:1.05, the...
Blowing and drifting snow disaster has caused great inconvenience to road traffic. It is necessary to take measures to slow down and avoid the climate disaster. The reasons of road hazard in blowing and drifting snow climate were discovered. This paper described the general formation mechanism of the blowing and drifting snow, considered the seasons that caused the snow damage for different embankment...
In image processing system, the target recognition is very crucial. An optimized algorithm based on the definition of block is presented. In this algorithm, two structure variables are self-defined to calculate the areas and centroids of targets. The labeling conflicts are resolved by tracking and correcting, which means that if there is a conflict, trace the neighbored blocks and correct the labels...
In this paper, a mathematical model is developed to analyze the deterministic economic ordering quantities (EOQ) for inventory system of remanufactured items with outsourcing. In the remanufacturing system, the manufacturer will outsource partial remanufacturing with its insufficient capacity. With consideration of different holding cost rates for serviceable items and non-serviceable items, we derive...
With large-scale gatherings frequently held recently, they caused a large amount of life solid waste in the short term, so timely and efficient handling of waste has become an important factor for large-scale gathering successfully. In this paper, logistics system of life solid waste in large-scale gathering was studied; first of all, putting forward the concept of logistics system of life solid waste...
In order to achieve the sustainable development in multi-span plastic covered greenhouse with high production efficiency, it was this research that established the mathematical model of the environment for cucumber production in coupling with the biological model of it, by making use of the knowledge of heat transfer, thermodynamics and the principle of energy balance as the research platform. The...
The analysis of transmission line under non-uniform incident field and with nonlinear loads is discussed in this paper. A test system is established according to IEC 61000-4-24, which consists of fast pulse generator and SPD (Surge Protection Device) test fixture. By using this system, the nonlinear Volt-Ampere characteristics of SPD can be measured and the nonlinear model of SPD is established. The...
Taking Shandong province as an example, the paper put forward the determination method of regional development axis and their importance and levels based on pole-axis theory. Firstly, the writers selected four regional development axes according to the conditions of choosing regional development axis, and then analyzed the ranges of the 4 axes and the cities and towns in the ranges with the method...
This paper investigates the wavelet transform and the principle and method of the noise reduction based on wavelet transform, chooses the threshold noise reduction, and discusses detailed the principles, features and design steps of the threshold method. Rigrsure, heursure, sqtwolog and minimaxi 4 kinds of threshold selection methods are compared qualitatively and quantitatively. The wavelet analysis...
Computer-assisted instruction systems have been broadly applied to help students solving math word problems. However, these systems offer little help to students encountering multi-step arithmetic word problems that do not be stored in the predesigned database. MSWPAS is a computer simulation system of people's arithmetic multi-step addition and subtraction word problems behavior, which composed of...
For nonlinear differential-algebraic equations subsystems satisfying linear growth conditions, the problem of output feedback stabilization control is considered in this paper. The design of the state observer and that of the controller are coupled. The proposed observer is non-initialized and linear which robustify the observer. Based on Backstepping approach, a linear dynamic output compensator...
This paper describes the application of value for money (VFM) test in public project and infrastructure to evaluate whether PPP route should be chosen. The role VFM test played in the determination of procurement method is illustrated, and then the main approach to VFM test is proposed, which is the comparison between PSC and PPP. In order to measure if PPP is more VFM than traditional procurement,...
Influences of fictitious economy on real economy appeared gradually in China. An empirical analysis about the influences was given by using quarterly data from April 1998 to December 2008. The results show that there is cointegration relationship between China's fictitious economy and real economy in the long term; there is Granger cause of the representative variables of China's fictitious economy...
Subjective and objective weights of indexes are determined respectively by G1 and entropy methods in the paper, furthermore, optimal weight is determined based on the Combination Weighting Method by minimizing the summary of the square of deviation. Finally, construct the financial risk evaluation model applied to the real estate and rank the order of related companies according to the comprehensive...
In order to control vegetable diseases and insect pests in the vegetable base, the ozonizer of SCM controlled is designed in this paper. The paper provides the system architecture of ozonizer and the IGBT inverter power supply. It also introduces the simulation design of control system by proteus, and gives the kind of problems and solutions occurred by ozonizer installation. The production of ozonizer...
The influences of the price level, trade and velocity of money circulation of fictitious economy on money supply appeared gradually. Empirical analysis of the influences of China' s fictitious economy on money supply was given by using the monthly data from April 1998 to December 2008 based on the actual development of Chinese economy and theory of money demand. The results show that there is cointegration...
Aiming at the wide application of SPWM sinusoidal modulation wave in the inverter circuit, the paper introduces a method of generating SPWM wave according to asymmetric regular sampling with the period and overflow interrupts of the event manager based on digital signal processor TMS320F2812, and adopts some harmonic suppression methods to obtain output waveform of high-precision. With the real-time...
The precision of temperature control is a very important factor to fermentation process. However, because the serious integral and time delay exists in the controlled object, the conventional control algorithm could hardly obtain satisfactory quality. Thus, a nonlinear PID controller is designed based on the nonlinear relationship between PID control parameters and error signals. Furthermore, an adaptive...
The research of LiangQi (2004) showed that there are certain differences between the labor intensive industry and the technology intensive industry regarding their agglomeration level and alteration characteristics. This paper did a further research about this phenomenon. The empirical studies based on Chinese provincial statistics (1986-2006) indicates that along with the change and development of...
