The paper considers the problem of minimizing the energy used to transmit packets over a wireless link via lazy schedules that judiciously vary packet transmission times. The problem is motivated by the following key observation: In many channel coding schemes, the energy required to transmit a packet can be significantly reduced by lowering transmission power and transmitting the packet over a...

SMT(Surface Mount Technology) machines are used to place electronic components onto a PCB(Printed Circuit Board). This study proposes a method of identifying the fastest path for picked up components to pass by a camera without stopping before being placed onto PCBs. The proposed method enables the gantry, responsible for moving the heads, to pass by the camera in the least amount of time possi...

This document describes an efficient augmented password-only authentication and key exchange (AugPAKE) protocol where a user remembers a low-entropy password and its verifier is registered in the intended server. In general, the user password is chosen from a small set of dictionary words that allows an attacker to perform exhaustive searches (i.e., off-line dictionary attacks). The AugPAKE pro...
