چکیده
Being abundant and non-polluted, solar energy is an increasingly desirable source. Growing research concerned about maximum acquisition from panels, especially in the automatic sun-tracking of panels. This paper presents a modified algorithm based on “PSA Algorithm” proposed 2001. And new tracking system with two-axis designed algorithm. The PSA used to calculate sun’s horizontal azimuth zenith angle combined time, longitude, latitude, other information. We prototype mainly composed microcontroller, Global Positioning System (GPS) module, digital compass, tilt sensor, 555 timer, gates, optical couples, H-bridge two stepper motors. Then using prototype, series experiments are conducted Tianjin City. Measured values were collected recorded original algorithm, compared actual Zenith Angle Sun comparison curves show that measurement accuracy higher than

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولExperimental verification of the modified spring-mass theory of fiber Bragg grating accelerometers using transverse forces.
A fiber Bragg grating (FBG) accelerometer using transverse forces is more sensitive than one using axial forces with the same mass of the inertial object, because a barely stretched FBG fixed at its two ends is much more sensitive to transverse forces than axial ones. The spring-mass theory, with the assumption that the axial force changes little during the vibration, cannot accurately predict ...
متن کاملExperimental Verification of the Butterfly Attractor in a Modified Lorenz System
An electronic circuit realization of a modified Lorenz system, which is multiplier-free, is described. The well-known butterfly chaotic attractor is experimentally observed verifying that the proposed modified system does capture the essential dynamics of the original Lorenz system. Furthermore, we clarify that the butterfly attractor is a compound structure obtained by merging together two sim...
