An investigation into how support vector machine can be used in the regression process of financial forecasting. A novel stock pricing model has been proposed based on the well-developed fundamental factors model and a combination of factors used in the model have been carefully selected to predict the common stock price. Several classical regression techniques therefore are applied separately in the predicting process and comparison has been made on the correctness of the predicted result. Support Vector Machine Regression has shown very strong competitivity throughout the test.

In order to increase electric cars power efficiency when control frequency conversion, and reduce the interference of high harmonics, we propose a design method of voltage space vector (SVPWM) frequency conversion control module. Based on TMS320LF2407 the PWM signal producing module design, IPM module as the core, we design the inverter circuit and Developed SVPWM real-time motion control program. This program use the manner of segmentation modulation, achieve frequency conversion control a range of 5 similar to 100Hz frequency. Variable frequency speed-governing experiment shows that, The control method can reduce the switching losses, meanwhile suppress the temperature rise.

In the contemporary competitive environment, the way that organizations generate, manipulate, select and make use of information about its customers has gained increasing importance for its potential to give the company an edge over competitors. Consumers demand a treatment increasingly personalized and products\services that better suit their needs, being receptive to actions that allow for greater interaction in the purchase process. The aim of this paper is to analyze the database marketing as a crescent usefulness tool, connecting businesses and consumers in the context of new market settings. With the appropriate structure can improve the integration and availability of data for customers, improving the company's performance, giving a more solid support at the level of decision making in business marketing activities and development strategies to acquire new customers, or ultimately helping to keep customers. These benefits become more significant in the digital economy.

In this paper presents a variable step-size algorithm for modified decision feedback equalizer structure with turbo coded for direct-sequence code division multiple access (DS/CDMA) digital communication systems. The main objective of the proposed equalizer is to minimize the bit error rate (BER) of the data due to the disturbances of noise and intersymbol interference (ISI) phenomenon on the channel. By the proposed technique, the performances of the proposed adaptive equalizer cooperate with the attractive soft Output Viterbi Algorithm (SOVA) algorithm of turbo decoder for the DS/CDMA system. It provides a good statistical in non-stationary channel condition scenario. The simulation results are shown the superior bit error rate performances of the proposed adaptive equalizer over other equalizers.

A measurement and control system based on Labview was developed for the performance research of high-pressure common rail diesel engine injector of marine. The developed system provides smooth high-pressure oil source for injector with just +/- 5MPa deviation to aimed pressure. It also function with data collection and calibration, fuel and hydraulic oil temperature controlling, pressure curve and injection rate displaying, data limits surpassing setting and alarming. The paper detail introduced the electronic components of the control system, software design and the PID closed-loop control of injection pressure.

It was found out that Hainan's county tourism development level was low with large internal diversity. County tourism development level was closely related with its geographical site, economic development level, tourism resource quality and policy support. It was suggested that Hainan county should take the significant opportunity of International Tourism Island construction. and pay much attention to transportation, marketing and tourism service improvement in order to achieve better achievement.
