Abstract During the loading operation of a ship loader in bulk terminal, in order to bring bulk cargo, such as coal and ore, precisely into every corner of the cabin and not to raise dust at the same time, the slip barrel mechanism usually is placed fully inside the ship cabin near the cargo as close as possible. However, if too close, it will increase the risk of collision between slip barrel and cargo, which poses a security risk to loading operation. This article proposes an anti-collision method for slip barrel in the process of automatic ship loading in bulk terminal. This method can accurately position the cargo of cabin which is blocked by slip barrel and shovel, and provide a reliable guarantee for the automatic loading operation. Firstly, this method use an array of laser radar mounted on the maintenance platforms to perceive the collision objects around the slip barrel, including the cargo and cabin. Meanwhile, it provides a compensation algorithm to reduce the effect of anti-collision recognition brought by dust and various obstacles during the operation. According to the calculated effective distance between the cargo and slip barrel, the automatic control system of ship loading can adjust the loading operation on a real-time basis. In the end, this article analyze and illustrate the reliability and validity of this method by the case of the application in automatic ship loading system in Tianjin coal terminal.

The paper discusses the process of integrating scientific equipment into the Russian Segment of the International Space Station (ISS RS) to conduct space experiment using the ISS IS information and control system. The paper addresses the stages in ground processing of scientific equipment that are critical for its successful operation after delivery to the ISS RS: tests on the hardware (vibration and hydraulic tests, electromagnetic compatibility tests, incoming inspection), development of the software for the equipment using ground debugging facility and conducting integrated tests in the checkout facility. It points out the need to update the existing stages of ground preparations for experiments to reduce the hardware ground processing time. Taking as examples the space experiment Terminator and experiments conducted using cargo transportation spacecraft Progress, the paper resents results obtained through the use of the described approach. Key words: information and control system, scientific equipment, space experiment, International Space Station, logistics spacecraft Progress, microgravity.

Sensor nodes have been assigned a lot of tasks in a connected environment that is growing rapidly. The power supply remains a challenge that is not answered convincingly. Energy harvesting is an emerging solution that is being studied to integrate in low power applications such as internet of things (IoT) and wireless sensor networks (WSN). In this work an interface circuit for a novel fluttering wind energy harvester is presented. The system consists of a switching converter controlled by a low power microcontroller. Optimization techniques on the hardware and software level have been implemented, and a prototype is developed for testing. Experiments have been done with generated input signals resulting in up to 67% efficiency for a constant voltage input. Other experiments were conducted in a wind tunnel that showed a transient output that is compatible with the target applications.
