Accurate Position

In the environment of harsh weather or obstacles, the corresponding monitoring department can't achieve remote control and acquire the accurate location of the unmanned aerial vehicle (UAV). According to the existing problem this paper designs a logical control module based on single chip microcomputer (SCM) C8051F040 and UAV real-time tracking system which is positioned by GPS. In this design, through the analysis and extraction of the GPS data, then transmit these data to the host computer through the USB interface with high speed, the unmanned aerial vehicle (UAV) flight vector position such as longitude and altitude information will be displayed by the host computer. After tested for several times, this vector pursuit system can acquire the accurate position of the unmanned aerial vehicle (UAV) and the corresponding flight path within 20 km. To some extent, it provides an effective guarantee for the remote control and monitoring department.

In recent years, 3D technology based on computer and internet has achieved high-speed development. People have realized direct and stereo observation of realistic world. Three-dimensional and visualized characteristics of the technology fit well with the teaching objective of college architecture specialized courses. Thus, 3D model has profound practical significance for its application in urban green space system and urban rural overall planning. With “urban-rural master plan” as experimental course, through design of “urban-rural master plan” multimedia teaching platform based on 3D technology and practice of the teaching platform in course teaching, this article has applied control experiment method and statistical method to make comparative analysis on the teaching effect difference of multimedia teaching platform based on 3D technology application in “urban-rural master plan” as experimental course so as to provide theoretical and data support for 3D technology application in “urban-rural master plan” and other college architecture major courses.

The Difference

The MEMS gyroscope used in Spinning Projectiles is a single-chip and axis gyroscope drive by high-speed rotary of Spinning Projectiles. To analysis this theory, a corresponding mathematical module was established based on the structural principle of the gyroscope and the Kinetic parameters included in the mathematical module was analyzed and calculation. By calculation, the paper had drawn the curve between the displacement of mass and the input angular velocity. By using ANSYS software the vibration mode and harmonic response have been done, after comparing the results of imitation and calculation, it is found that the difference is little, so the theory based on the displacement of mass is correct.

The recent increase in popularity of portable systems and rapid growth of packaging density in VLSI circuit’s has enable designers to design complex functional units on a single chip. Power, area and speed plays a major role in the design and optimization of an integrated circuit. Carry select adder is high speed final stage adder widely used in many data processing units. In this work, conventional D-flip flop is replaced by a new design using negative edge triggered D-flip flop. The proposed CSA is implemented in a faster partitioned Dadda multiplier and simulated by using MICROWIND tool. The results reveal that for 16 bit CSA improvement of power delay product (PDP) of the proposed design using negative edge triggered D flip flop is 78% & 18% when compared to CSA with BEC and CSA with conventional D flip flop. When CSA implemented in a partitioned Dadda multiplier it results in performance improvement of 74 % with little increase in total power dissipation.
