Wideband Wireless Communication

Ultra-wideband wireless communication technology is brought, in the coal mine communications in this paper in order to raising the safe level of communication in coal mine. Ultra-wideband wireless communication is a system which is transmitted by the extremely narrow pulse transmission. An avalanche transistor is the core of extremely narrow pulse circuit. Narrow pulse wave form can be simulated by multisim software. Acquiring the results of simulation is the extremely narrow pulse whose pulse amplitude ranging from 10 v to dozens v and pulse width is about 3 seconds. In addition to this circuit carries on the theoretical analysis, the results is quite consistent with the simulation value in this paper.

In this article, we have presented various techniques that are used for improving different parameters related to UWB antenna. In this Paper, we planned for MIMO antennas in contemporary wireless communication which enhances the bandwidth and gives compact antennas. The antenna band we notched is of planned MIMO which offers an bandwidth with the operational band-notched. The bandwidth capacity of the antenna is from 2.93-20 gigahertz with sharp rejection at WLAN-band with isolation of not exactly - 22 dB is accomplished for the whole band, by utilizing a simple modified shaped structure in the bottom plane, port isolation and transmission capacity are improved. The diversity execution performance is likewise contemplated and whole outcomes shows it’s a potential point of using MIMO based diversity antenna for ultra wide band applications which is demonstrate in this paper. The parameters to assess the performance of the MIMO are explained, the whole examination completed in different sections has been outlined

Feeding Control

In order to improve the quality of modern dairy industry, it is an inevitable trend to implement intensive control feeding of dairy cows, which is also the development direction in the future. Different feeding methods have different important effects on the health of dairy cows. For example, calves grow and develop rapidly during lactation, change their physiological structure quickly, have strong plasticity, poor inversion and imperfect digestive function. In the production of dairy farms, the scientific feeding mode of calves indirectly affects the overall benefits of dairy farms. Therefore, aiming at the above problems, this paper studies how to accurately control the quality of dairy cows. A cow precise feeding control system based on wireless communication technology and cow information management technology is studied, which solves the problems of wireless information transmission, automatic and accurate cow identification and dual-mode operation of feeder, and ensures the accurate supply of cow concentrate.

In this proposition, a traditional UWB antenna with twofold indent channels was intended for a few remote applications. The exhibited antenna is outlined having estimations of 30 × 35 × 1.6 mm3 with a fix of rectangular staircase design. The dismissal bands are WLAN at 5 GHz (5.1 - 5.8 GHz) and the satellite X-band from space to earth (7.25 - 7.75 GHz). The patch with a step design with a modified π-formed opening gets the ultra-wide band. The UWB scope of 3.1 - 10.6 GHz affirmed by FCC can possibly cause interferences in the various wireless systems applications.. With a specific end goal to lessen these interferences, we settled on the band indent. In this proposed outline, the WLAN has scores setting a U-molded opening in the patch and the X-band has indents with a reversed T-shape in the ground plane.

The so-called e-commerce refers to the ESD (Electronic System of Distribution) which can be achieved in the areas of enterprises through the modern network and information technology, including the issuance and exchange basic information of the network, enterprises promotion, pre-market advertising, after-sales service and electronic distribution by electronic means, as well as, internal process and the electronic management information system applications of enterprises. In order to accommodate the complex network data of large scale companies, this thesis analyses PMI, strategy and role hierarchical model. On such a basis, the thesis proposes an applicable plan for access control of enterprises information system based on attribute certificate. These new entrants are often backed by advanced technology companies and competitive organizations with funds from Chinese and foreign conglomerates. Therefore, the applications of e-commerce in the field have brought about the information of business operations and internal management, which can provide consumers with a higher quality of services. In this paper, the enterprises information management and organization will be discussed in the e-commerce. Currently the technology of information and network develops rapidly. As a result, e-commerce, e-government and e-office prevail over our society and have become a part of our life. This situation enhances the efficiency of work and changes for the enterprises information management in China.
