A local TCAD model of the ballistic mobility is proposed that can be used in quantum drift-diffusion (QDD) simulations. It can be combined with models for density gradient correction and source-to-drain tunneling (STDT). These quantum effects strongly affect the transfer characteristics of In 0.53 Ga 0.47 As double-gate ultra-thin-body (DG UTB) FETs with ultra-short channels.

We report the first mechanically flexible amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) vertical thin-film transistors (VTFTs) with 500 nm channel length, fabricated on a freestanding plastic foil, using a low temperature process 107 and a threshold voltage of 2.2 V. We demonstrate full device functionality down to 5 mm bending radius, even after 1000 bending cycles. These results proof that VTFTs are feasible for realizing compact and bendable electronic systems.

This article presents image processing methods for biological Images which show kind of cells. The main difficulty of processing these images was the presence of noise in the images and the limitation of losing pixels during the binarization of the images. Neighborhood algorithm, such as the Wiener filter was used for noise removal. In addition to this, a normalization of the background was performed on the image before the binarization of the image and finally the application of morphological operations for suppressing the remaining effects of the noise on the original image.

The present work develops a multibody dynamical model of a planar biped robot called Rabbit, the same that considers external forces which act at the moment of the ground-feet contact. Moreover, the ground-feet contact forces where modeled. The multibody dynamical model of Rabbit was implemented in Robotran, software that generated symbolic files of the dynamical equations of the model in Matlab syntax. These dynamical equations and the ground-feet contact external forces were implemented in a Simulink model for simulation purposes. The model was validated though a Simulink implementation of the torque generator and control blocks of the real robot. The results showed that the model required adequate torques, which must be generated on the basis of designed trajectories, assuring the dynamical stability of the gait. In addition to this, the adequate frictional forces acting on the feet of the model proved to prevent the robot from slipping on the walking surface and falling. In conclusion, for achieving a stable gait, an adequate dynamic model that assures stability is not only necessary, but a correct design that could be fitted for the torque generator of the real robot is necessary as well.
