A particle filter algorithm was used to simulate a Remotely Operated underwater Vehicle (ROV) tracking a moving target in 2-D space. The simulation modeled the behavior of a Sea Perch ROV modified with mounted cameras to perform blob-tracking on the target. Thirteen different noise levels were sampled for both distance and angle, with 100 trials per noise level. The angular noise demonstrated a...

Abstract Using Remotely Operated Vehicles (ROV) is very important, especially in underwater investigations. The Madura Strait, located between the Java islands and Madura, used as an industrial area, for oil gas sources. Therefore, ROV structure must be designed such a way that it can withstand hydrostatic loads receives during operations deep sea. study was conducted to determine ROV’s ability...

Skeletal muscle blood flow increases rapidly with exercise onset, but little is known of where or how the rapid onset of vasodilation (ROV) is governed within the microcirculation. In the retractor muscle of anesthetized hamsters (n = 26), we tested the following: 1) where in the resistance network ROV occurred, 2) how microvascular responses were affected by the duration of contraction, and 3)...

A multiplayer version of SimROV is presented based on Virtual Reality and Artificial Intelligence. It includes a submarine scenario where an operator of an ROV can analyze some maneuvers to the installations of several oil wells. The system includes consoles for an instructor and for one or more students, and all of them share a common scenario, each participant has control over its own ROV alt...

In the last decades, robots have been used to explore areas hard to reach for humans. Underwater environments fall into this category, since their operating conditions make even simpler operations risky to be carried out by divers, especially when they have to be performed at high depth. A possible approach to overcome this problem is to use a Remotely Operated Vehicle (ROV), although this easi...

For decades, PID (Proportional + Integral + Derivative)-like controllers have been successfully used in academia and industry for many kinds of plants. This is thanks to its simplicity and suitable performance in linear or linearized plants, and under certain conditions, in nonlinear ones. A number of PID controller gains tuning approaches have been proposed in the literature in the last decade...

Underwater Remotely Operated Vehicles (ROVs) have a significant support role to play in offshore petroleum production facilities. The extent to which ROVs can replace diver-based operations depends significantly on ROV capacity and the relative costs of mobilising and implementing the two modes of underwater operation. This paper presents work directed at two aspects of ROV operability: the qua...

This article presents the policy of Government Republic Vietnam (RoV) to manage economic activities Chinese community in South Vietnam. In particular, study highlights objective and subjective reasons that prompted ROV government adopt stringent measures limit influence points out benefits limitations these measures. Lessons learned from community's management policies 19551975 also help resear...
