QUESTION
I am stuck at this point, I am trying to clean the row name of a table using postgresql. The table is for districts in wales and England.
What I am trying is to delete the strings 'District', '(B)', 'London Boro' and everything before the hyphen in the dual English - Welsh name, for example (Swansea - Abertawe) I would like to eliminate everything before the hyphen (I would like to know how to do it in both direction anyway) and get (Abertawe). I manage with the first 3 strings but with the part of hyphen I cannot find the solution to the issue.
I have tried using replace and trim but I don't obtain the result desired.
This is code as I have tried the last time:

QUESTION
I am writing a simulation script which involves 2-UUV and 1-USV. Both Underwater vehicle doing surveying in orthogonal lawnmower motion model. I would like to stay in the range of both vehicle, so they started at the same origin point. I want to know that How can define USV
motion model in such a way that it is always in the communication range of both UUV
's for most of the time.
- Basically How can I manually provide dynamic path planning/ motion model to
USV
so that I can communicate to bothUUV
most of the time ? Is it even possible ? Could someone provide a basic example of this or point me in the right direction ?
Here is my simulation script :
...ANSWER
Answered 2021-Apr-26 at 07:55The Unet simulator supports multiple levels of motion models depending on the required complexity in the simulation.
The NodeInfo agent in each simulated node implements a basic dynamics model. The model is turned on using the mobility
flag which can be set in a simulation script or directly on the NodeInfo
agent. When mobility
is enabled, the agent automatically updates location
based on motion parameters such as speed
and heading
using the simple dynamics model. This can be handy to simulate the motion of a node, for example, an AUV swimming away from an underwater modem.
We can easily do this by manually updating the parameters of one of the nodes in a simulation. Use the 2-node-network
example from Unet IDE. The "Map" view of the IDE is handy to visualize the motion of nodes. Connect to the WebShell of Node A and set the mobility
, heading
, and speed
parameters. As the simulation continues the location of Node A will continue to be updated based on the speed
and heading
.
