(i) The given schedule is not conflict serializable. To determine conflict serializability, we need to draw a precedence graph. The precedence graph for this schedule is as follows:

T1: R1(y) - W3(x) T2: R2(y) - W2(x) - R2(x) T3: R3(y) - W3(y) - C3 - R3(x) - W1(x) - C2 In the precedence graph, we can observe a cycle (T3 -> T1 -> T2 -> T3), which indicates that the schedule is not conflict serializable. (ii) If W3(x) of T3 is changed to R3(x), the changed schedule will be conflict serializable. The precedence graph for the changed schedule will be: T1: R1(y) - W3(x) T2: R2(y) - W2(x) - R2(x) T3: R3(y) - R3(x) - W3(y) - W1(x) - C2 - C3 In this case, there are no cycles in the precedence graph, and hence, the schedule is conflict serializable. In summary, changing the write operation in T3 to a read operation makes the schedule conflict serializable by changing the precedence relationship between T3 and T1.

The Custom_FP_48 system uses 48 bits to represent numbers, and the type of numbers it can evaluate is not specified. The width of representation is not provided, and the maximum precision is also not specified.

The Custom_FP_48 system is a floating-point number representation that uses 48 bits to represent a number, similar to the IEEE 754 standard. The number representation consists of three parts: the sign, the exponent, and the mantissa.

The sign bit is used to represent whether the number is positive or negative. The exponent field is used to represent the power of 2 to which the mantissa is multiplied. The mantissa is the fraction part of the number.

In this system, the types for evaluating the number are single-precision (32-bit) and double-precision (64-bit). The width of representation for these numbers is upper 3.4x10³⁸and lower -3.4x10³⁸.

The maximum precision is determined by the number of bits in the mantissa field, which is 23 bits for single precision and 52 bits for double precision.

To print the multiples of 7 between 0 and 100, we can use a for loop and check if each number is divisible by 7 using the modulo operator. Here's a sample script:

```python
for i in range(0, 101, 7):  # start at 0, end at 100, increment by 7
   if i % 7 == 0:  # check if the number is a multiple of 7
       print(i)
```
This script uses the `range` function to generate a sequence of numbers from 0 to 100, with a step size of 7. Inside the loop, we check if each number is divisible by 7 using the modulo operator (`%`).

If the remainder of the division is 0, then the number is a multiple of 7, so we print it using the `print` function.

Note that we only print the number if it's a multiple of 7, to avoid printing any numbers that aren't multiples of 7. Also, we include 0 as a multiple of 7, since it's divisible by any number.

The systematic technique for constructing software architecture while conducting tests to uncover faults associated with interfacing of components is known as Test-Driven Architecture (TDA).

In TDA, the architecture is created by writing tests that specify the desired behavior of the system. These tests are then executed against the architecture, and the results are analyzed to identify any errors or faults. The architecture is then modified to correct the errors, and the process is repeated until the architecture satisfies the desired functionality and quality attributes.

It ensures that the architecture is designed to meet the requirements of the system. Secondly, it helps to identify faults early in the development process, which reduces the cost of fixing them later. Thirdly, it helps to increase the quality of the software by identifying and eliminating faults associated with the interfacing of components.

To prevent a circular wait among the resources R1, R2, and R3 with integer values 15, 10, and 25 respectively, we can use a resource ordering based on the values of the resources. One possible resource ordering that prevents a circular wait is:

R2 < R1 < R3

This means that a process requesting resources must acquire them in the order of R2, then R1, and finally R3. With this ordering, a circular wait is prevented because no process can hold a resource while waiting for another resource that is held by another process.

For example, if a process holds R2 and wants to acquire R1, it can do so because R1 is lower in the ordering. If it wants to acquire R3, it must release R2 and then acquire R1 first, and only then can it acquire R3. This prevents any circular wait scenarios where two or more processes are waiting for each other's resources, which could lead to a deadlock.

To find the number of 5-element multisets whose elements belong to the set {1, 2, 3, 4, 5} such that at least two elements in each multiset are distinct, we can use the principle of inclusion-exclusion.

First, we will find the total number of 5-element multisets, which can be found using the formula (n + k - 1) choose k, where n is the number of elements in the set and k is the size of the multiset. In this case, we have n = 5 and k = 5, so the total number of 5-element multisets is (5 + 5 - 1) choose 5 = 126.Next, we will subtract the number of multisets in which all elements are the same. There are 5 possible choices for the single element that appears in the multiset, so there are 5 such multisets.However, we have subtracted too many multisets, because we have also counted those in which two elements are the same twice. To correct for this, we will add back the number of multisets in which two elements are the same. There are 5 choices for the repeated element and 4 choices for the other element, so there are 5 * 4 = 20 such multisets.We have now corrected for the double-counting of multisets with two repeated elements, but we have also counted too many multisets in which three elements are the same. To correct for this, we will subtract the number of multisets in which three elements are the same. There are 5 choices for the repeated element and (3 choose 2) = 3 choices for the other two elements, so there are 5 * 3 = 15 such multisets.Finally, we have corrected for all double-counting, but we have also subtracted too many multisets in which four or five elements are the same. However, there are no multisets in which all five elements are the same, and there is only one multiset in which four elements are the same (namely, {1, 1, 1, 1, 2}). So we have not subtracted too many multisets in these cases.Putting it all together, the number of 5-element multisets whose elements belong to the set {1, 2, 3, 4, 5} such that at least two elements in each multiset are distinct is:
126 - 5 + 20 - 15 = 126 - 5 + 5 = 126 - 0 = 126.

To accurately answer your question, I would need more context or information about the specific code segment you are referring to. However, I can provide a general answer regarding binary search (bSearch) method calls.

In a binary search algorithm, the number of times the bSearch method is called depends on the size of the dataset being searched and the position of the target value. On average, the bSearch method will be called log2(n) times, where n is the number of elements in the dataset. This includes the initial call as well.If the bSearch method is called 5 times in the code segment, including the initial call, it means that the code is likely using a binary search algorithm to search for a particular value in a sorted array.In a binary search, the array is repeatedly divided in half until the target value is found. Each iteration of the algorithm splits the remaining search space in half, so the number of iterations required to find the target value is logarithmic with respect to the size of the array.
