LTE femtocell is very popular in communication fields. The size and the cost of LTE femto BS should be paid more attention. Here, we designed a low cost MIMO RF transceiver for LTE femto base station, which also has small size. After the analyses of the transmitter and receiver requirements, we put forward block level RF parameters. In the paper, the RF transceiver was separated into many sub-modules;...
Entrepreneurship is the intangible resource of economic growth, and increasingly becomes the important microcosmic impetus of the technology innovation and economic growth. According to the connotation of entrepreneurship and the theory of regional economic development, this paper established an evaluation index system of entrepreneurship and the method of principal components analysis (PCA) was adopted...
This paper establishes the evaluation index model to evaluate the competitiveness of sci-tech intermediary service industry in Heilongjiang Province based on Principal Component Analysis(PCA). Totally 16 indicators that can reflect the competitiveness of sci-tech intermediary service industry are set in the index model. By use of PCA, this paper selects three principal components: development environmental...
To avoid the BP (Back-Propagation) Network's disadvantages of low training speed, prone to trapping in a local optimum and poor capability of global search, this paper establishes the model of manual neural network energy prediction system based on generic algorithm with the research on the Mn-Si alloy smelting of a steel company, by optimizing the initialized weights and threshold of neural network...
Cost decision of activity-level serves the improvement of activity, In allusion to the specialized-automobile manufacturing enterprises, this paper builds a data model and its algorithm of cost decision on the basis of object - standard - activity-based costing (OS-ABC) method, which provides data support for it, On the basis of the theory of decision tree in allusion to specialized-automobile manufacturing...
Now cost accounting popularly adopts the activity-based costing (ABC) method, compared with the traditional method, its precision is higher. In allusion to special automobile enterprises, this paper designs four models and two algorithms to the logistics of cost accounting and control(CA/C), which provides a theoretical support for it. And puts forward an object - standard - activity-based costing...
Unit electricity consumption is important indicator on production of Mn-Si alloy. There exists a serious nonlinear relationship among unit electricity consumption and the ferromanganese's grade and furnace average power and the amount of ferrosilicon powder and the amount of coke and daily average output etc. The predictive model of Mn-Si Alloy Smelting Energy Consumption based on Double Wavelet Neural...
A new kind of electronic and mechanical antitheft lock using digital code based on the technologies of DSP, serial communication and wireless data transmission is introduced. This lock has several functions with good security, identification and alarm-giving. It is simple and has wide application and high reliability. Hardware frame and software flowchart of the system are presented as its function,...
To avoid the BP (Back-Propagation) Network's disadvantages of low training speed, prone to trapping in a local optimum and poor capability of global search, this paper establishes the model of key based on generic algorithm with the research on the key shape, by optimizing the initialized weights and threshold of neural network with GA. After the test of the program complied by MATLAB language and...
Daily average output and unit electricity consumption are two important indicators on production of Mn-Si alloy. There exists a serious nonlinear relationship among daily average output and unit electricity consumption and the ferromanganese's grade and furnace average power and the amount of ferrosilicon powder and the amount of coke etc. The predictive model of Mn-Si Alloy Smelting Energy Consumption...
In order to overcome the problem that the least square support vector machines (LS-SVM) using Gaussian kernel cannot approximate arbitrary signal with multi-scale, a scaling ker-nel for LS-SVM is proposed. LS-SVM can be used simultaneously to approximate to the target function and improve the effectiveness of generalization and approximation in the local area model. The LS-SVM with scaling kernel...
Partnership management has become a hot issue of corporation management in recent years. This paper analyzes the structure of partnership of entrepreneurial supply chain (ESC) and the influential factors of its stability combining the principles of relation management and the characteristic of GUANXI culture. Structural Equation Modeling (SEM) is used to examine how various types of factors of GUANXI...
This paper analyzes the structure of cooperative relations of entrepreneurial supply chain (ESC) and the three -level influential factors of its stability. The factors of GUANXI culture have effect on the stability of cooperative relations of ESC. Then some assumptions are given based on the impact of GUANXI culture to these factors and Structural Equation Modeling (SEM) is used to test the assumptions...
Supplier relation management (SRM) is an important link in enterprise management. The keen competition makes the relation between the enterprise and supplier is no longer simple buying and selling relationship, but should be intimate colleagues with mutual trust and contribution. This paper takes SX Illumination Company as the case to study its improvement of the SRM. It starts from the Chinese GUANXI...
It is reported that only 3% of total Web users via B2B in China have bought online in 2005, most transactions via B2B were in the pattern that can be described as "online transaction, offline payment". Most researchers have focused primarily on infrastructural issues to solve this problem, but we find that Chinese "Guan Xi" culture is tightly linked to "offline payment"...
