Answer:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.
Answer:
Giving that: The following is a sequence of undo-log records written by 2 transactions T and U:
< START T >;
< T,A,10 >;
< START U >;
< U, B, 20 >;
< T, C, 30 >;
< U, D, 40 >;
< Commit U >;
< T, E, 50 >;
< Commit T >;
1. < START U >
Recovery action in this case will be undo(-1) and undo(0). All restored to its original Value
log records < T, A, 10 >, < T, abort >; as written out
2. < T, E, 50 >
Recovery action in this case will be undo(8) and redo(0). A and C is restored to its original value, B and D are set to 20 and 40
log records <T, C, 30 >, < T, A, 10 >, < T, abort > are written out
3. < Commit T >
Recovery action in this case will be redo(7) and redo(4). A and C are set to 10 and 30, B and D are set to 20 and 40

The decisions that a specialized drone delivering medical supplies make once it's algorithm has started and it is scanning its surround are:
- A tilt backyard when sensor detects an obstacle within 10 feet.
- To disable self flying and alert pilot when sensor detects an obstacle within 3 feet.
- To resume normal speed when sensor doesn't detect an obstacle within two feet.
<h3>How are drones used in healthcare?</h3>
Hospitals are known to have started using drones to transport laboratory samples and also to carry out other kinds of humanitarian aids.
The use of drones is said to be one that is cost-effective and it is one that bring blood products, vaccines, medical supplies, and others to rural areas or areas that has small infrastructure.
A drone can find way to move around obstacles but they should not shut down where there is obstacle.
