In the usual framework of control, a reference trajectory is needed as set point for feedback controller. This can be generated by solving optimization problem. problem continuous optimal control (OCP) that transcribed into finite-dimensional nonlinear (NLP) and solved SQP. For an underactuated conventional vessel, mathematical model very intricate, hence NLP itself. causes significant computat...

The idea of an extension life for CubeSats is proposed to reduce space debris in a low-earth orbit. In this work, gripper designed geometry-based grasping berthing tasks. operation outlined square- and rectangle-shaped CubeSats. Equilibrium conditions are formulated design the fingertips’ shape parameters CubeSat bodies. A scheme provide required accuracy. concept developed into lab prototype b...

The significance of ports in global trade activities has a significant impact on city, region, and even nation. A port with adequate facilities superior system will make more effective, neutral, simple for its users. Inaportnet is facility that currently used by major Indonesian ports, including the Tanjung Emas Semarang. users this include exporters, importers, shipping lines, others, addition...
