Convergence of manufacturing industry and ICT becomes a new competence and it is

Drones in flight make a variety of vibration frequencies. Therefore, gimbal system is needed to get clean images from drone-mounted cameras. The system consists of two things: one is a structure to support a camera module, and another is a stabilizer to block outside vibrations and keep the right angle. The purpose of this paper focuses on the system's dynamics model and the application of a traditional PID controller. Furthermore, the paper compares the traditional PID and intelligent-PID without any dynamics model through the simulation made of MATLAB/Simulink.

<p>Identifying the causes of marine accidents is difficult because of problems in scene preservation, reenactment, and procuring of witnesses. Thanks to new regulations, larger vessels are now required to carry voyage data recorders (VDRs) and automatic identification systems (AISs). However, the content of these devices, which is created, stored, and managed digitally, has security vulnerabilities such as the potential for data modification. Therefore, when managing digital records it is important to guarantee reliability. To this end, we suggest a digital forensics-based digital records migration method using a hash algorithm to guarantee the integrity and authenticity of digital records.</p>
