This paper focusses on the hydrodynamic performance of an unmanned vehicle system, consisting a remotely operated underwater (ROV) that has to be launched and recovered autonomously from Autonomous Surface Vehicles (ASV). The model ASV/ROV coupled system is described in detail solved numerically. seeks assess overall including stability ASV, ROV tidal current capacity required power launch reco...

A cathepsin B-like cysteine protease belonging to family C1 is abundantly expressed in the transcriptome and proteome of the carcinogenic liver fluke of humans, Opisthorchis viverrini. This enzyme is present in excretory/secretory (ES) products released by parasites cultured in vitro. This study evaluated the performance of recombinant O. viverrini cathepsin B1 (rOv-CB-1) as an antigen for immu...

This paper describes the application of using a submersible remotely operated vehicle (ROV) to map and explore underground water cisterns during a series of expeditions to Malta and Gozo. The purpose of this project was to create maps of ancient cisterns located under private homes, churches, and fortresses where passageways leading to the cisterns are too narrow and dangerous for humans to ent...

During prion infections, the cellular glycosylphosphatidylinositol-anchored glycoprotein PrP is converted into a conformational isoform. This abnormal conformer is thought to recruit and convert the normal cellular PrP into a likeness of itself and is proposed to be the infectious agent. We investigated the distribution of the PrP protein on the surface of Rov cells, an epithelial cell line hig...

Remotely operated vehicles (ROVs) are useful tools for aquatic research, but are underutilized because of the high operational costs and limited versatility of older models. Scientifically useful ROVs were originally very expensive to purchase or lease, and costly to operate with limited models available. With an increase in the number of models available and lower operating costs, the use of R...

The article is directly related to the authors’ previous study of remotely operated underwater vehicle’s (ROV) motion, where mathematical model ROV motion derived for laminar flow water. This solution has been improved by using three-dimensional computational fluid dynamics (CFD) simulation that allows simulating turbulent flow, which mainly generated propellers. Both methods were coupled obtai...

Evidence is presented from publicly available remotely operated vehicle (ROV) footage that suggests deep-water ranging in ocean sunfishes (family Molidae) is more common than typically thought, including a new maximum depth recorded for the southern sunfish Mola ramsayi.

This paper presents an algorithm (SPEAR) for visually estimating the pose and shape of an underwater target without fiducials. The goal is to enable AUV/ROV stationkeeping with respect to targets about which nothing is known a priori. It will also enable relative positioning with respect to any face on the 3-D body. It uses a particle filter to simultaneously track the pose and reconstruct a 3-...

A crawling Remotely Operated Vehicle (ROV) has been developed for scientific activities within coastal and estuarine regions of the ocean for multiple research activities such as environmental impact assessment and integrated coastal zone management. The Modular Amphibious Research Crawler (MARC-1) ROV is designed to operate underwater and in the surfzone to a depth of five meters. The vehicle ...
