The invention relates to a group of novel phenylpiperazine derivatives with a dual mode of action: serotonin reuptake inhibition and partial agonism on dopamine-D2 receptors. The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. This system attains a low error rate even when the signal-to-noise ratio of an input signal is low, and avoids pulse edges with low phase detection accuracy or signal pulse streams with a high possibility of being mistakenly detected as an edge in conventional methods, and also supports diverse types of input signals. Thus, bubbling of lubricant and production of sludge, which may otherwise be caused by agitation of the lubricant surface, can be prevented.
