In recent years, with the development of data warehouse and Web technology, more and more attention has been paid to multiple applications of the data in warehouse. However, data quality issue is one of the biggest obstacles to the success using of data warehouse project for many enterprises. So a data audit model is proposed and the relevant methods are studied in the study based on the characteristics of the telecommunications industry. Further, a three data layer audit method, consisted of audit mode data file level, record level and index level, is constructed during Extraction Transformation Loading (ETL) process. It can effectively improve the data quality of data warehouse. |

This system uses Mitsubishi PLC and computer configuration
screen monitoring control mode, press the button or picture can complete automobile
access process, simple operation, easy access. Control circuit of traditional
way by ac contactor, safe and reliable operation. Through the configuration
software, database construction, the animation process control, connection and
debugging, realized the monitoring system of three-dimensional garage. Finally
discusses in detail the design of control system based on the two layers of
garage structure for three models. Finally discusses in detail the design of
control system based on the two layers of garage structure for three models.
Lift the solid carport, its part can be divided into three parts: the garage
structure parts, motivation and control system is part. According to lift the
operating principle of the solid carport, on the fluctuation of three-dimensional
garage control system design, uses the advanced PLC control, using the software
Mitsubishi of lifting the solid carport control procedures, commissioning, operation
and proved by using the Programmable Logic Controller (PLC) as the control system
is simple. |

With the continuous development of society and the prevalence of computer and network technology. How to ensure the security of information in the course of transmission have become the most important things for people at present. With this background, we studied how to realize encryption and decryption of the RSA (Initials of Ron Rivest, Adi Shamirh, LenAdleman) encryption technology. This study mainly introduces the application of RSA algorithm in encryption and decryption, mentions the technology of digital signature. Also introduces in the process of implementation of RSA algorithm in Visual Studios environment and operation results. Using this system for encryption and decryption of information, theoretically, good results were obtained in safety and reliability. |

The beyond 3G or 4G mobile systems are envisioned to be characterized
by the pouring of diverse services supported by various RANs (Radio Access Networks)
belonging to different operators. In parallel with this, how to utilize efficiently
the limited radio spectrum and guarantee the operator’s
profits has emerged as a joint economical and technical problem. As a possible
solution, in this study, a bilateral bargaining approach is proposed for Dynamic
Spectrum Management (DSM) based on bargaining games under incomplete information
in microeconomics. In the context of distributed reconfigurable networks controlled
by different operators, bilateral bargaining DSM (BBDSM) scheme introduces Trading
Agents (TA), trading mechanisms as well as reasonable bargaining strategies
to facilitate DSM. Related technologies, bargaining games and proposed algorithm
are also described in details. Simulation results show that with imperfect load
predicting, BBDSM is effective in improving the utilization of spectrum, expanding
the individual operator’s profits. |
