Your question is related to the two-process mutual exclusion problem published in the January 1966 issue of Communications of the ACM. You would like a detailed counterexample that illustrates the problem, while considering simple assignment statements like turn = 0 as atomic.

The given solution for mutual exclusion contains shared data and code for each of the two processes. Here's a counterexample that shows this solution doesn't work:

1. Process 0 enters the while loop and sets blocked[0] = true.
2. Process 1 enters the while loop and sets blocked[1] = true.
3. Process 0 checks the value of turn, which is currently 0, and skips the first inner while loop.
4. Meanwhile, process 1 checks the value of turn, which is still 0, and enters the first inner while loop.
5. Process 0 enters the critical section and sets blocked[0] = false.
6. Process 1 now checks the value of blocked[0] in the first inner while loop, sees that it is false, and exits the loop.
7. Process 1 sets turn = 1, but since process 0 has already set blocked[0] = false, process 1 enters the critical section even though process 0 is still inside its critical section.

This counterexample demonstrates that the given solution does not ensure mutual exclusion because both processes were allowed to enter their critical sections simultaneously.

A binary search tree (BST) is created from an initially empty BST with the following numbers inserted in the specified order. The two possible trees that result after deleting the root are then shown.

56, 77, 33, 26, 17, 25, 88, 45, 90, 83Inserting 56 into an empty tree creates the following BST:In order to preserve the BST property, 77 should be inserted as the right child of 56. As a result, the tree will look like this:

To maintain the BST property, 33 should be inserted to the left of 56 as a left child of 56. The tree will look like this:Since 26 is less than 56, it should be inserted as the left child of 33. The resulting tree is as follows:

17 should be inserted as the left child of 26 since it is less than 26. The resulting tree is as follows:

Since 25 is less than 17, it should be inserted as the right child of 17. The tree will look like this:

To preserve the BST property, 88 should be inserted to the right of 77. The tree will look like this:

45 should be inserted as the left child of 88 since it is less than 88. The tree will look like this:

To maintain the BST property, 90 should be inserted to the right of 88. The tree will look like this:83 should be inserted as the left child of 90. The tree will look like this: Deleting the root 56 from the BST results in the following two possible trees;In order to remove the root, it must be replaced with its inorder successor, which is 77.

As a result, 77 becomes the new root of the tree, and the left and right subtrees are attached. The resulting tree is as follows:Removing 56 from the right subtree of 56 in the original tree results in the following: The inorder successor of 77 is 83 in this tree.

As a result, the right child of 77 should be replaced with 83 to preserve the BST property. The resulting tree is as follows:

The binary search tree (BST) is constructed from an initially empty tree by inserting the given values in the specified order. We then removed the root node and examined the two possible trees that result. We found that 77 became the new root of the tree and that the left and right subtrees were linked. We were able to maintain the BST property in both trees by replacing the root node with its inorder successor, which is 77 and 83.

Answer:

For  lower disk :   V = e^θ​rω(0)/h  = 0

At the upper disk:  V = e^θ​rω(h)/h  = e^θ​rω

Hence The physical boundary conditions are satisfied

Explanation:

Velocity field ( V ) = e^θ​rωz/h

Upper disk located at  z = h

Determine the dimensions of the velocity field

velocity field is two-dimensional ; V = V( r , z )

applying the no-slip condition

condition : The no-slip condition must be satisfied

For  lower disk Vo = 0 when disk is at rest z = 0

∴  V = e^θ​rω(0)/h  = 0

At the upper disk  V = e^θ​rω  given that a upper disk it rotates at z = h

∴ V = e^θ​rω(h)/h  = e^θ​rω

Hence we can conclude that the velocity field satisfies the appropriate physical boundary conditions.

Enthalpy is the thermodynamic potential of a system at constant pressure. It indicates how much energy is stored in a system in the form of heat.

The change in enthalpy is equal to the amount of heat absorbed or released by a system at a constant pressure. Internal energy,  is the sum of all the microscopic energy states of a system. It includes the kinetic and potential energy of all the particles in a system. The change in internal energy is equal to the amount of heat absorbed or released by a system at a constant volume.

d) One aspect of the second law of thermodynamics is that it states that entropy of an isolated system always increases over time. Entropy is a measure of the randomness or disorder of a system. This means that over time, the amount of usable energy in a closed system will decrease, and the amount of unusable energy will increase. For example, when a hot object is placed in contact with a cold object, heat energy will flow from the hot object to the cold object until they reach thermal equilibrium.

During this process, the entropy of the system will increase, as the energy becomes more dispersed and less organized. This is why it is impossible to create a perfect heat engine that can convert all of the heat energy into work, without any loss of energy or increase in entropy.
