the memristor is formally defined^[4] as a two-terminal element in which the magnetic flux φ_m between the terminals is a function of the amount of electric charge qthat has passed through the device. each memristor is characterized by its memristance function describing the charge-dependent rate of change of flux with charge.

noting from faraday's law of induction that magnetic flux is simply the time integral of voltage,^[9] and charge is the time integral of current, we may write the more convenient form

memristor symbol.

wonderful ego product from Denmark.

the mmc, a product of collaboration between the national institute of standards and technology (nist) and the ieee robotics and automation society to create the mobile microrobotics challenge, features seven teams competing with micron-scale robots on three tasks. in the two-millimeter dash, the robots will sprint down a track the size of a pinhead. in the second task, the robots will attempt to insert correct pegs into the correct holes. the final freeform task will be up to the teams, but is supposed to demonstrate system reliability, a high level of autonomy, ultra low power consumption and high task complexity.

Ever though about high tech japan. Take a look at this great construction to prevent a person getting wet from the moister leakage of the air-conditioner.

Scientists at the Fraunhofer Research Institution for Electronic Nano Systems together with colleagues from Chemnitz University of Technology and Menippos GmbH (all based in Chemnitz, Germany) collaborated on product development. They are targeting applications such as smart credit cards with battery-powered displays to show balances and other account information.

New light made by yuka hayashi and rob oudendijk. the back of the light projects an ASCII symbol I made a few years ago. presenting two persons kissing.

birthday button. designed by yuka hayashi (my darling). concept is my birthday expressed in small green and black rhinestones. the green diamonds are the pointers in the decimal counting from bottom to top. the columns present the place of the date starting with the year. the black diamonds are the not pointers. so the first colum reads 2 the second reads 0 and so on. so totally 20081130.
