Abstract: Along with the continuous improvement of China's science and technology, pattern recognition calculation methods have attained a rapid development, among which the new algorithms have been popularized and applied in pattern recognition. The angle of pattern refers to the intersection angle between two adjacent vectors, and owns the geometrical characteristics such as stretching, displacement, and rotation invariance, which are better unification for pattern characteristics. In this paper, the angle-based pattern recognition algorithm is mainly analyzed.

Abstract: The control system is the main device to carry out executive action in enterprise, which assists the drivers' action inside the vehicles based on the actual route and maintains the running stability of the car so as to reduce the negative impact from the outside conditions on vehicle performance. In essence, radio frequency identification (RFID) technology belongs to the application of communications technology, which uses wireless transmission signal to identify and lock target identification, and then establishes corresponding information transmission mode, thus providing a virtualized operation platform for the target operation and control. This paper firstly analyzes the defects of the current auto control system, introducing the characteristics of RFID technology's application to auto control. Secondly this paper analyzes the design of GPS navigation control system based on RFID technology, so as to hope to make a useful contribution to the follow-up research.

Abstract: Security problem is the main factor restricting economic development of architecture. Fire accident, in particular, results in serious casualties and losses. As building structural layout is more diversified, there are more and more assembly forms of internal structures and facilities. Automatic fire alarm system is the key in building design and construction. The thesis first of all makes an analysis of the current construction fire accident, points out the application function of fire alarm system and analyzes automatic fire alarm system circuit junction, hoping to contribute to further studies.

Abstract: Passenger flow is the circulating with purpose which is formed by human beings who want to achieve all kinds of trip activities through the help of various transportations. It is an important studying content in controlling the city traffic as well. As for the necessary monitoring of passenger flow, the primary condition is grasping the precise passenger flow data and mapping out an effective monitoring plan based on the facts and data. The paper first introduced the necessarily in monitoring and the appliance of usual calculating method of passenger flow. Based on this, the paper also put forward the managing and analysis of data information in the calculating methods of passenger flow monitoring, which is hoped to be helpful in the future research.

Abstract: By testing water quality analysis of part of the import and export of wastewater pretreatment facility catering units in Kunming shows that these pre-processing facilities catering units emit water SS, COD, BOD5, Anionic Surfactants and Animal and Vegetable Oils compliance rate is not high, exceeded the phenomenon is more serious .It shows most pretreatment facilities catering units Kunming currently flawed，and these indicators can not be treated all the standards. Some pretreatment facilities of catering units should based on the test results improving and strengthen management.

Abstract: Recently, 3D printing technology has obtained the rapid development which brings immeasurable changes. It is considered to be one of the main marks of the third industrial revolution. The shares of Avic Heavy Machinery co., Ltd (600765) involving 3D printing technology continuously hardened six times in January 2013.Taking it as an example, we expound the connotation and advantages of 3D printing technology seriously and also elaborate the background of 3D printing technology. In addition, by analyzing its operation ability, profitability and growth capacity, we find the shares of Avic Heavy Machinery co., Ltd (600765) hardened on account of 3D concept hype, and not its performance. Then we describe the existing problems in the development of 3D printing technology in our country. Finally we give some corresponding suggestions to the development of 3D printing technology from three angles.

Abstract: Gliclazide is a second generation sulfonylurea, which is used as antidiabetics drug. It is orally administrated and used for the treatment of non-insulin-dependent diabetes mellitus (NIDDM) and has duration of action of 12 h or more. Beside its hypoglycaemic effects, gliclazide was reported to have many other important effects, such as: suppression of platelet functions, antithrombotic actions, decreased the production of tumour necrosis factor (TNF) α by endothelial cells and other effects. The unique activities of gliclazide has open a new avenue for the drug development research. This work is aimed to provide comprehensive information about gliclazide and its current research activities.

Abstract: This paper firstly starting mechanism of vibration and noise from gear, gear noise mechanism is explained, and analyze the factors and the impact of noise on the gear reducer. Secondly, the establishment of a complete solid model of gear reducer and reducer model for finite element model, the reduction gear box gear reducer of modal analysis and finite element modal calculation, and points out the dynamic analysis of structure, size and weight factor is proportional to the reciprocal of the modal frequencies of each mode is the with the frequency is low, that is, the greater the weight. Once again, the main measure of load and control of gear noise of gear is analyzed, including the calculation, for exciting force reduction gear reducer gear load computation. The analysis and calculation are the theoretical basis of gear structure design and its performance evaluation.

Abstract: The low-voltage distribution system is the key component of the electrical power system. Some analysis and research of the low-voltage distribution system is carried out in this paper, which provides some scientific basis to design the low-voltage distribution system. Firstly, the summarize of low-voltage distribution system is taken. The influence to productions and livings of low-voltage distribution system is introduced. Secondly, the mode of connection and design philosophy of low-voltage distribution system is studied in detail, especially the high-rise buildings low-voltage distribution system is concluded and summarized.

Abstract: Recently, with the rapid development of the window-cleaning, we need set up a scientific design and renovation method. This paper based on the working principle of fixed window-cleaning, we deduced the design methods of the mast when its parameters changed followed the variation of the working condition. Then, we ensured the most dangerous working condition. And in this condition, we made an analysis of the mast based on ANSYS and found out the regularities of distribution of the stress. At last, it could provide worthy reference for the design of mast.
