But that is where he intended up. fortunately enough as mentioned before, he cap tized and sglrmgt and he made the decision to stay with the boat and right the boat and that made a factor to find him with c-130 who found him with radar and vectored in to closely acquire him with the camera and a visual contact. we had boats operating in the area as well on different search pattern, so we were able to diverse boats on and recover him, and get him to shore quickly. again, the system worked very close and st. augustine and florida fish and wildlife, and that made the difference in this
Factor in being able to locate it, and they knew that the ultimate destination was the titanic and that gave them a good feel for, you know, where to fine tune their search pattern, and ultimately that served to be the key. how are they going to it s by the titanic, so it s not, you know, obviously in the wreckage, which would have made it a whole lot harder because the titanic is a protected site, and that would have been a real effort to not disturb the site but also to remove the wreckage, are they going to be able to bring up to the surface the remaining pieces of this submersible? i believe they are. we ve used rovs for salvage operations for decades. and the rovs that they have there, if they re the runs that i believe they are will be able to assist with that, and if for the larger pieces they have that
Lights, cameras, and manipulators and they can be controlled by a surface operator. they are connected to the surface vessel with an umbilical. and so they go down. they will reach the seabed. once they ve reached the seabed, they have to locate where they are. once that is done, they will begin a search pattern. now, the lights, it is pitch black down there. so the lights are going out in front of it. and the camera will be recording everything that happens in front of them. and the pilot of the vehicle, up on the ship, he will manage it and fly it in a grid pattern.
The general vicinity that it likely was because it was going down to the titanic, finding it 1,600 feet off the hull of the titanic, though, it s still a small you know, it s a needle in a hay stack. it s a minivan in the vast ocean. how were they able to locate this so quickly? it is surprisingly that the location happened quicker than in some of our salvage operations. i think the fact that they had the data for where the titan entered the water made it i don t want to say an easier search pattern, but between that, the use of the sona buoys, and the help of those rovs, those deep ocean rovs that they were able to get on the scene in the last day or so was a big
That s why they have started searching in that area. they haven t confirmed that those sounds were the titan, but they haven t confirmed that it wasn t the titan. they haven t ruled it out. now sent some robs in that area to try to fine tune whether or not those sounds are relevant. that s how you do a search pattern. and that s all they have right now. so they re looking there. mike, when we talk about the nearly 90 hours they ve been in there at this point, right, you went down and back up. it was a few hours. ten hours. so now it s 90 hours, close. were you trained on anything, on what to do if it lost communications. did you know if there was food, or did you know what to do if
when you re working i mean, we re looking at images right now of people climbing over a pile of what we would call rubble. how do you what do you where do you begin? so, you know, so what they re doing here, in this particular footage, they re obviously searching by hand. that s why they have the buckets. they re taking brick by brick, stone by stone, debris by debris, into a bucket and taking it off the pile, looking for voids, looking to see they ll bring cameras in. sometimes they ll have the dogs walk on the pile first. and i assume it s got to be done kind of by hand, at this stage, because you don t want a backhoe going to an area where there may be somebody. right. so for really obviously, large, heavy structures, you re not going to be able to move them, so then you get the heavy equipment to move it, and then once that s de-layered, you can do the hand by hand, piece by piece, doing the different devices, infrared, heat-sensitive equipment. do you divide it
Abstract
As cloud storage has been widely adopted in various applications, how to protect data privacy while allowing efficient data search and retrieval in a distributed environment remains a challenging research problem. Existing searchable encryption schemes are still inadequate on desired functionality and security/privacy perspectives. Specifically, supporting multi-keyword search under the multi-user setting, hiding search pattern and access pattern, and resisting keyword guessing attacks (KGA) are the most challenging tasks. In this article, we present a new searchable encryption scheme that addresses the above problems simultaneously, which makes it practical to be adopted in distributed systems. It not only enables multi-keyword search over encrypted data under a multi-writer/multi-reader setting but also guarantees the data and search pattern privacy. To prevent KGA, our scheme adopts a multi-server architecture, which accelerates search response, shares the workload, and

It, you know. we had been searching quite a bit of area, covering it really, really well, we were using gps technology so we knew exactly where we had been searching and we haven t found another piece of evidence that led us away from that area and we hadn t smelled anything strange, we hadn t found anything strange. we were like, well, that only means that she s just still moving. that s why we haven t found her. tell us about the moment that you spotted her while you were in the helicopter. it was it was it was it was magic. it was it was elation. we re flying up, going up this what we call a george coming up, there is a waterfall and stream and pretty much we re going up with the helicopter, there was a waterfall, there was a waterfall, there was a stream, a waterfall, a stream. we are hanging off these helicopters and, you know, we were having to turn around. we were at the end of this search pattern because the helicopters only have a certain
