This work studies the effect of PEDOT:PSS on electrical, optical and mechanical properties of ITO glass. Various thickness PEDOT:PSS films are deposited on ITO glass by spin coating. The sheet resistance, transmittance, surface roughness, residual stress, friction, and critical load of the coated specimens are tested in sequence. We find that PEDOT:PSS films not only improve the electric performance...
Research on ¡§How to create a fair, convenient attendance management system¡¨, is being pursued by academics and government departments fervently. This study is based on the biometric recognition technology. The hand geometry machine captures the personal hand geometry data as the biometric code and applies this data in the attendance management system as the attendance record. The attendance records...
With the penetration of the Internet and the rapid development of information technology, the secure transmission of the text and image herewith gets a great deal of attention. The traditional methods of encryption can only maintain the information security. However, the information could be cracked and to proceed criminal acts by the illegal use of the relevant information. Therefore, it is necessary...
Packet losses and errors are common through current wireless transmission due to signal decay, barriers in-between and other environmental related reasons. Although there are many ways to correct these errors, there is no one can deal with them immediately. For the efficient use of energy to achieve the purpose of energy conservation, and use the smallest energy to implement monitoring more, rapid...
Offshore fish farms are very popular along the southwest coast of Taiwan. In order to breed more fishes in the limited land, it is usually way by high density breeding. But it immediately causes dissoluble oxygen deficiency in the water. Therefore aerator which can supply extra oxygen in the water is common to use in fish farms. Normally aerator is powered by electricity; the utility will be a disbursement...
This paper presents a creative design for a motion stage. The system consists of a stepping motor, a stage, a potentiometer, two wires, and spring. The design is based on changing the length of a wire while the wire is being twisted. According to the experimental results, it is disclosed that the positioning accuracy of the stage will reach to plusmn 0.02 mm at each step. The advantages of the design...
