Using a coarse-and-fine actuator combination (dual stage system), a new design of the three degree-of-freedom (DOF) micro parallel positioning platform with high mobility, high accuracy, and a large working space is proposed. To achieve these three DOFs and implement the dual stage system, there are six possible architectures for the coarse and fine actuators, respectively. This paper is organi...

this paper mainly focused on implementation of aes encryption and decryption standard aes-128. all the transformations of both encryption and decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. this method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theaes inversesub bytes module and...
