Recall the following notation from set theory. If A and B are sets, then AUB (the union of A and B) is the set of elements that belong to either A or B (or both). For example, if A {1,2,19) and B = {2,3,4} then AUB={1,2,3,4,19). If W is the universal set, and C is a subset of W, then-C denotes the complement of C (relative to W), that is, the set of elements of W that are not in C. For example, if W = {1,2,3,...,20) and C = {1,2,8,14,17,19) then -C = {3,4,5,6,7,9,10,11,12,13,15,16,18,20).

Answers

Answer 1

a. E denotes the event representing the proposition "Ann is in Paris". So, E = {a, c}.F denotes the event representing the proposition "Ann is in London". So, F = {b, d}.b. KB E denotes the event representing Bob knows that Ann is in Paris, that is, Bob knows that E has occurred.

So, KB E = {a}.K CariaE denotes the event representing Carla knows that Ann is in Paris, that is, Carla knows that E has occurred. So, K CariaE = {a, b, c}.Kcaria(KEU KobF) denotes the event representing Carla knows that Bob knows where Ann is, that is, Carla knows that either Bob knows that Ann is in Paris or Bob knows that Ann is in London.

So, Kcaria(KEU KobF) = {a, b, c, d}.d. G denotes the event "Ann is in Paris and Bob does not know that Ann is in Paris". So, G = {c}.

David considers G possible" denotes the event representing David considers it possible that Ann is in Paris and Bob does not know that she is in Paris. So, David considers G possible = {a, c, d,}.

As discussed in this (Links to an external site.) article, grocery store companies have engaged in design-thinking initiatives to identify solutions with which to attract more shoppers to make more-persistent use of those companies' stores. Consider the example of New York-based Food Cellar and Gala Fresh stores, which are investing in technology-enabled solutions to compete against mighty Amazon's Whole Foods. (Amazon has begun to use this technology in some of its Whole Foods stores.)
Rather than retrofitting the stores themselves, these operators plan to equip shopping carts with everything you need to automate a checkout. The carts connect with stores’ point-of-sale systems, making this a simple software integration, rather than a costly hardware installation.
As shoppers pick an item from a shelf, cameras and sensors on the cart "scan" the product and add it to the shopper’s tally. The cart can also weigh loose items, such as vegetables, to calculate a price, and it may even recommend additional ingredients if it thinks you’re making a specific dish. "It looks like you’re making Spaghetti Bolognese, you might want some Parmesan cheese to go with that," is the general idea here. The cart will even guide you to the Parmesan cheese.
For most students, it's somewhat intuitive to answer the questions of whether this design-thinking solution passes the tests of feasibility and desirability. But quite a few students struggle when trying to assess a proposed solution is viable.
To help you with that, I invented the following completely made-up but logically sensible pro forma financial analysis of the viability of this proposed solution. Here's the image, followed by questions that will help you make sense of this analysis:
On line # 1, I assumed that the convenience of this solution, combined with the effect of the in-store recommendations to buy some Parmesan cheese to go with that, will increase in-store sales by $100 per year.
On line # 2, I assumed that Caper will integrate the data collected from the customer's in-store experience to give that customer a more-informed online-shopping experience, such that customers will make more online purchases from Capers and recommend Caper's to their time-pressed, and none-too-price-conscious friends.
On line # 4, I assumed that operating this new technology-enabled system will increase the cost of operating stores by $25.
On line # 5, I assumed that integrating that new system with existing online-shopping systems will cost $100, which includes the yearly amortization of the investment that was required to implement this system.
On line # 9, I assumed that the amount of that investment was $1000.
On line # 10, I calculated that the incremental return on invested capital (which is a different name for RONA) is 24.8%.
On line # 12, I calculated that the RONA minus the guesstimated WACC of 10% equals a positive spread of 14.8%. That performance will place this investment high in the blue wedge:
From my itemized list, you can see how the spreadsheet model integrates thinking across all dimensions of your business study. This is similar to how an MIS integrates the use of data from all dimensions of an organization's operations. Finally, I hope you're beginning to see how the design-thinking process integrates all of the above into a holistic model that explains and predicts an organization's success for its shareholders and its stakeholders. This is why I love teaching this course; my experience is that students find it useful to see how so many ideas and streams of study can come together to create a holistic (if as-yet shallow) understanding of a business enterprise.

When selecting a primary key for a database table, the criteria that should be considered are as follows: It should have a value for every record (not allowed to be null)It should uniquely identify each row in a database table. It should be stable (not subject to change).

Primary Key is a unique identifier used to identify the records in a database table. It is a type of constraint used to identify each row uniquely in a table. When selecting a primary key for a database table, it is necessary to choose a column that fulfills all the criteria mentioned above. It should be unique, stable, and have a value for every record. In addition to this, the primary key is used to create relationships between tables. It helps to join multiple tables by defining foreign keys. The foreign key is used to create a reference to the primary key of another table to create a relationship between tables.

Therefore, all the possible answers mentioned in the given question are correct. However, there are other criteria to consider when selecting a primary key, such as simplicity, consistency, and relevance to the data. The overall process of successively decomposing tables to minimize data redundancy, thereby avoiding anomalies and conserving storage space is known as Normalization. It is used to ensure data integrity and improve the efficiency of the database.

There was a small fishpond which is approximated by a half-body shape. A water source point O located at 0.5 m from the left edge of the pond, delivers about 0.63 m³/s per meter of depth into the fishpond. Find the point location along the axis where the water velocity is approximately 25 cm/s. (10 marks) (b) Plot the flow net for an incompressible flow defined by u = 2x and v= -2y.

Answers

The point location along the axis where the water velocity is approximately 25 cm/s can be found by calculating  the flow rate  in fluid mechanics and determining the corresponding point.

Given that the water source delivers 0.63 m³/s per meter of depth into the fishpond, we can calculate the flow rate at the desired velocity as follows:

Flow rate = 0.63 m³/s per meter of depth

Velocity = 25 cm/s = 0.25 m/s

Flow rate = Velocity * Area

Determining the Point Location:

To find the point location, we need to calculate the area. Since the fishpond is approximated by a half-body shape, we can use the formula for the area of a rectangle:

Area = Length * Width

Width = Depth of the fishpond = y

Length = Distance from the water source point O to the desired point location = x

By substituting the values into the equation:

0.63 m³/s per meter of depth = 0.25 m/s * (x * y)

We can solve for x:

x = (0.63 m³/s per meter of depth) / (0.25 m/s * y)

The obtained value of x will give us the point location along the axis where the water velocity is approximately 25 cm/s.

Plotting the flow net for an incompressible flow defined by u = 2x and v = -2y is not possible with the given information. The flow net requires additional information such as boundary conditions or specific points to plot the flow lines accurately.

Therefore, the point location along the axis where the water velocity is approximately 25 cm/s can be found by calculating  the flow rate  in fluid mechanics and determining the corresponding point.

A stone is drop from the top of the building 50 m high. After it has fallen 10 m below. as second is thrown vertically upward from the ground. What must be the initial velocity of the second stone so that both reach the ground at the same time? a, 9.78 m/s c.7.14 m/s b. 18.62 m/s d. 8.63 m/s

Answers

Therefore, the initial velocity of the second stone must be 18.62 m/s so that both reach the ground at the same time. So, option (b) is correct.

Height of the building = 50 height from which the second stone is thrown = 0 height from where the first stone was dropped = 40 the first stone has covered a height of

50 - 40 = 10 m

before the second stone is thrown. Therefore, the height from which the second stone is thrown is

50 - 10 = 40 m.

As the time taken by both stones to reach the ground is the same, therefore, using the kinematic equation for falling object, we can find the time for the first stone to reach the ground.

S = ut + 1/2 at²

Where u = initial velocity of the first stone

= 0 (as it is dropped)S

= distance fallen by the first stone

= height of the building

= 50 m.a

= acceleration due to gravity

= 9.8 m/s²t

= time taken by the first stone to fallSolving for t, we get:

t = sqrt (2S/a)On substituting the given values, we get:

t = sqrt (2 × 50 / 9.8) ≈ 3.19 s

Now, using the kinematic equation for the second stone,

S = ut + 1/2 at²

Where u = initial velocity of the second stone

S = distance travelled by the second stone

= height of the building - height from where the second stone is thrown

b. Similarly, the code does not determine the maximum memory capacity in bytes as it is not relevant to the RANSAC algorithm.

c. The code does not involve memory addresses or accessing memory, so there is no concept of the last memory address the CPU can access.

d. The code does not relate to memory access or the size of memory data access, so it does not provide information on the maximum memory address space if memory data access were 16 bits instead of 32 bits.

A circular footing with diameter 3.1m is 2.9m below the ground surface. Ground water table is located 1.1 m below the ground surface. Using terzaghi's equation, determine the gross allowable bearing capacity assuming local shear failure using the following parameters: = 27 degrees c = 32 kPa y = 18.4 KN/m³ ysat = 24.6 KN/m³ FS = 3

Answers

To determine the gross allowable bearing capacity using Terzaghi's equation, we need to consider the following information:

Diameter of the circular footing (D): 3.1 m

Depth of the footing below the ground surface (H): 2.9 m

Depth of the groundwater table below the ground surface (Hw): 1.1 m

Effective soil unit weight (γ'): 18.4 kN/m³

Saturated soil unit weight (γsat): 24.6 kN/m³

Cohesion of the soil (c): 32 kPa

Angle of internal friction (φ): 27 degrees

Factor of Safety (FS): 3

First, let's calculate the effective stress at the base of the footing:

Effective depth of the footing (D')

= H + Hw

= 2.9 m + 1.1 m

= 4.0 m

Effective stress at the base (σ') = γ' * D'

= 18.4 kN/m³ * 4.0 m

= 73.6 kN/m²

Next, we need to calculate the total vertical stress at the base:

Total depth of the footing (D_total) = H + Hw + D = 2.9 m + 1.1 m + 3.1 m = 7.1 m

Total vertical stress at the base (σ_total) = γsat * D_total

= 24.6 kN/m³ * 7.1 m

= 174.66 kN/m²

Now, let's determine the effective stress contribution from cohesion:

Effective cohesion (c') = c * (FS - 1)

= 32 kPa * (3 - 1)

= 64 kPa

= 64 kN/m²

Finally, we can calculate the gross allowable bearing capacity (qall):

qall = (σ_total - σ') + c'

= (174.66 kN/m² - 73.6 kN/m²) + 64 kN/m²

= 165.06 kN/m²

Therefore, the gross allowable bearing capacity for the circular footing, considering local shear failure and the given parameters, is 165.06 kN/m².

To obtain a parallel realization for the given transfer function H(z), we need to factorize the denominator and rewrite the transfer function in a parallel form.

Given:

H(z) = (-11z - 16) / [(z^2 + z + 12)(z^2 - 4z + 3)]

First, let's factorize the denominators:

z^2 + z + 12 = (z + 3)(z + 4)

z^2 - 4z + 3 = (z - 1)(z - 3)

Now, we can write the transfer function in the parallel form:

H(z) = A(z) / B(z) + C(z) / D(z)

A(z) = -11z - 16

B(z) = (z + 3)(z + 4)

C(z) = 1

D(z) = (z - 1)(z - 3)

The parallel realization of H(z) is:

H(z) = (-11z - 16) / [(z + 3)(z + 4)] + 1 / [(z - 1)(z - 3)]

To implement this parallel realization, you can consider each term as a separate subsystem or block in your system. The block corresponding to (-11z - 16) / [(z + 3)(z + 4)] would handle that part of the transfer function, and the block corresponding to 1 / [(z - 1)(z - 3)] would handle the other part.

Please note that the specific implementation details would depend on your system and the desired implementation platform (e.g., digital signal processor, software implementation, etc.). The parallel realization provides a structure for organizing and implementing the transfer function in a modular manner.

Von Neumann architecture is an early computer architecture that is based on the idea of storing instructions in the same memory as data. This design has a separate memory unit and a central processing unit (CPU).The architecture is used to provide a programming model that includes a separate memory and processor. The programming model is based on the fact that both the data and the instructions that operate on the data are stored in the same memory and are treated the same way. The Von Neumann architecture separates memory and processing because it allows for faster processing speeds.

The memory and processing units can work simultaneously, allowing the computer to work more efficiently. The main disadvantage of the classical Von Neumann architecture is the bottleneck between the CPU and the memory. This bottleneck slows down the processing speed of the computer, making it slower and less efficient. This is because the CPU must wait for the memory to respond before it can access the data it needs. This delay in response time can cause the CPU to slow down or become inefficient.

Current solutions to this bottleneck include the use of caches and multi-core processors. Caches are small, fast memory units that store frequently accessed data. Multi-core processors, on the other hand, allow for multiple CPUs to be integrated into one computer. This allows for more efficient processing of multiple tasks at the same time.The Von Neumann architecture is still used today, but there are also other computer architectures that have been developed since its inception. These architectures are designed to overcome the limitations of the classical Von Neumann architecture.

what is the purpose of the flow divider in a turbine engine duplex fuel nozzle? group of answer choices allows an alternate flow of fuel if the primary flow clogs or is restricted. creates the primary and secondary fuel supplies. provides a flow path for bleed air which aids in the atomization of fuel.

Answers

The flow divider in a turbine engine duplex fuel nozzle is designed to create the primary and secondary fuel supplies. The correct option is B.

The flow divider plays a crucial role in turbine engines. It is essential in duplex fuel nozzle systems to ensure an equal distribution of fuel to the combustion chamber. It creates a path that divides the fuel into two separate streams. One is the primary flow that goes through the primary fuel nozzle. The other is the secondary flow that goes through the secondary fuel nozzle.The secondary flow comes into play during high engine loads or high-altitude operations. The flow divider increases the pressure of the primary and secondary fuel streams. This makes it possible for a more stable and reliable fuel flow to the combustion chamber.What are duplex fuel nozzles?Duplex fuel nozzles are a type of fuel injector that delivers fuel to the combustion chamber. They have two separate nozzles that deliver fuel to the primary and secondary combustion zones. The nozzles work in conjunction with the flow divider, which creates the two separate fuel streams that go to the nozzles.

Air is kept in a tank at pressure Po = 689 KPa abs and temperature To = 17°C. If one allows the air to issue out in a one-dimensional isentropic flow, the flow per unit area at the exit of the nozzle where P = 101.325 KPa is -------- kg/m2-s. For air, Use R = 287 J/kg-K and Mol. Wt. = 29.1

Answers

Given:Pressure at the initial state Po = 689 kPa Temperature at the initial state To = 17°C Pressure at the final state P = 101.325 kPa Molecular weight of air M = 29.1 g/mol = 0.0291 kg/mol Gas constant R = 287 J/kg-K The mass flow rate of air through the nozzle is to be determined.

Assuming the flow to be adiabatic and steady, the mass flow rate can be found using the isentropic flow equations given by the following:ma = (A*V) / (Vg)where A is the area of the nozzle throat, V is the velocity of the gas through the nozzle throat and Vg is the specific volume of the gas at the nozzle throat.Using the ideal gas law, the specific volume of the air at the initial state can be found as follows:PV = mRTm = PV/RTwhere P = Po, T = To, R = R/M, and V = 1/mSince P and V are known, m can be calculated from the above formula. The mass of air is then conserved throughout the nozzle, therefore the mass flow rate at the nozzle exit can be taken as the mass flow rate at the nozzle throat.Thus, we can write:ma = (A*V) / (Vg) = ρA * V where ρ is the density of air, which can be calculated from the ideal gas law:ρ = P/(RT).

The velocity of air at the nozzle throat V can be found using Bernoulli’s equation:P/ρ + V²/2 = constant P1/ρ1 + V1²/2 = constant At the nozzle throat, the pressure is Po and the velocity is zero, therefore:P/ρ = Po/ρoV²/2 = Po/ρo - P/ρSince the flow is isentropic, [tex]Po/ρoγ = P/ργV = sqrt(2*γ*R*T/(γ-1) * (1 - (P/Po)^((γ-1)/γ)))[/tex]Finally, the mass flow rate can be calculated by substituting the value of V and ρ in the equation for ma:[tex]ma = ρA * sqrt(2*γ*R*T/(γ-1) * (1 - (P/Po)^((γ-1)/γ)))ma = P*A/RT * sqrt(γ*R*T/(γ-1) * (1 - (P/Po)^((γ-1)/γ)))[/tex]Substituting the values given, we get:ma = 0.0566 kg/m²-s (approximately)Therefore, the flow rate per unit area at the exit of the nozzle is 0.0566 kg/m²-s.

For in-use inodes, each address in use is also marked in use in the bitmap. If not,
print ERROR: address used by inode but
void check_alloced_blocks_marked() {
// List code here
}

Answers

In order to check if each address in use is also marked in use in the bitmap or not, the `check_alloced_blocks_marked()` method can be used. If the address is being used by the inode but is not marked in use in the bitmap, then an error message is printed which states "ERROR: address used by inode but".

The code block for the `check_alloced_blocks_marked()` method is as follows:
```
void check_alloced_blocks_marked() {
 int i, j;
 for (i = 0; i < sb.s_inodes_count; i++) {
   struct ext2_inode inode = inodes[i];
   if (inode.i_size > 0) {
     for (j = 0; j < 12; j++) {
       if (inode.i_block[j]) {
         if (!get_block_bitmap_bit(inode.i_block[j] - 1)) {
           printf("ERROR: address used by inode but marked free in bitmap.\n");
         }
       }
     }
     if (inode.i_block[12]) {
       check_single_indirect(inode.i_block[12]);
     }
     if (inode.i_block[13]) {
       check_double_indirect(inode.i_block[13]);
     }
     if (inode.i_block[14]) {
       check_triple_indirect(inode.i_block[14]);
     }
   }
 }
}
```

The `check_alloced_blocks_marked()` method is used to verify if each address in use is marked as used in the bitmap or not. It works by iterating over all inodes and checking their blocks. If an inode has blocks allocated, then it checks each block for whether it is marked as used in the bitmap or not. If a block is found to be in use by the inode but is not marked as used in the bitmap, then an error message is printed to the console.

The method checks the direct blocks (i_block[0] to i_block[11]) of an inode and then checks the indirect blocks (i_block[12], i_block[13], and i_block[14]) if they exist. It does this by calling the `check_single_indirect()`, `check_double_indirect()`, and `check_triple_indirect()` methods respectively.

In summary, the `check_alloced_blocks_marked()` method is used to ensure that all allocated blocks are marked as used in the bitmap. If an allocated block is not marked as used in the bitmap, then there is a logical error in the file system.

The `check_alloced_blocks_marked()` method checks if each address in use is also marked in use in the bitmap or not. If an error is found, it prints an error message to the console. The method checks the direct and indirect blocks of an inode and ensures that they are marked as used in the bitmap. This helps to identify logical errors in the file system.

A certain microphone is capable of delivering 0.5 V when someone claps their hands at a distance of 10 ft. A particular electronic switch has a Thevenin’s equivalent resistance of 620 Ohms and requires 100 mA to energize. Using Op-Amp, design a circuit that will connect the microphone to the electronic switch in such a way that the switch is activated by someone clapping their hands. Show the details of your, including the circuit with labels.

Answers

The electronic switch will be activated when someone claps their hands, thanks to the Op-Amp circuit design.

The microphone generates a voltage of 0.5 V when someone claps their hands 10 feet away. The voltage is fed to the non-inverting terminal of the Op-Amp through R1. The resistors R2 and R3 make up the voltage divider, which sets the voltage level on the inverting terminal. The voltage at the inverting terminal is about 1.5 V, which is slightly more than half the supply voltage, due to the voltage divider. The Op-Amp's output is either positive or negative. The output is high, which is about the supply voltage, when the voltage at the non-inverting terminal is greater than the voltage at the inverting terminal. In this case, the output is low, which is about 0 V, when the voltage at the non-inverting terminal is less than the voltage at the inverting terminal. The output of the Op-Amp, therefore, swings between the supply voltage and 0 V. The 620 Ohms resistor, which represents the Thevenin's equivalent resistance of the electronic switch, is connected between the Op-Amp output and the base of the transistor. The transistor is turned on by the Op-Amp, and current flows through the relay coil when the transistor is on. When the switch is closed, the circuit is completed, and the electronic switch is activated.

Thus, the electronic switch will be activated when someone claps their hands, thanks to the Op-Amp circuit design.

One sample t-test is used to determine whether the sample mean is significantly different from the hypothetical or expected mean. The result of a t-test is expressed in t-statistics. These statistics are then compared to a t-distribution table to determine whether they are statistically significant or not. The given data has a t-value of -9.0783, df=9, p-value=7.953e-06,

alternative hypothesis: true mean is not equal to 25, and a 95% confidence interval of 17.8172 to 20.6828.

These values can be interpreted as follows:

The t-value of -9.0783 represents how many standard errors the sample mean is away from the expected value of 25.

The df of 9 represents the degrees of freedom of the t-distribution.

The p-value of 7.953e-06 indicates that the probability of getting a t-value this extreme by chance is very low, which suggests that we can reject the null hypothesis.

The confidence interval of 17.8172 to 20.6828 represents the range within which we are 95% confident the true population mean lies. Sample estimates mean of x is 19.25.

Therefore, we can conclude that the sample mean is significantly different from the expected value of 25, and we can be highly confident that the true population mean falls within the range of 17.8172 to 20.6828.

e) In the circumstances of part d) calculate the rise in the dc link voltage that would occur.

Answers

The rise in dc link voltage will be: ΔVDC = 10 mH * (10A / t).

When an emergency stop procedure results in all four switches being turned off, the energy in the load will result in a reverse voltage to the inverter. The load current will form a path via the inverter’s intrinsic diodes and the dc link capacitors. As a result, the energy stored in the load will be transferred to the dc link capacitors.

The inverter’s intrinsic diodes will enable the discharge of the dc link capacitors, allowing the dc link voltage to be boosted by the stored energy. This mechanism will trigger the voltage of the dc link to rise, resulting in high dc link voltage.

The effect of the stored energy transfer on the inverter voltage is similar to that of an inductor, which contributes to the rise of the dc link voltage. In this scenario, the rise in dc link voltage, VDC can be calculated by the following formula:

ΔVDC = L * (di/dt)

Where L is the inductance of the load, which is 10mH. We know that the load current, i = 10A.

Therefore, the rate of change of current, di/dt can be calculated as follows:

di/dt = i / t

Where t is the time for the switches to turn off.

Therefore, the rise in dc link voltage will be:

ΔVDC = 10 mH * (10A / t)

It is basically the preemptive version of First come First Serve CPU Scheduling algorithm. Round Robin CPU Algorithm generally focuses on Time Sharing technique. The period of time for which a process or job is allowed to run in a pre-emptive method is called time quantum. Each process or job present in the ready queue is assigned the CPU for that time quantum, if the execution of the process is completed during that time then the process will end else the process will go back to the waiting table and wait for the its next turn to complete the execution. Characteristics of Round Robin CPU Scheduling Algorithm: It is simple, easy to implement, and starvation-free as all processes get fair share of CPU. One of the most commonly used technique in CPU scheduling as a core. It is preemptive as processes are assigned CPU only for a fixed slice of time at most. The disadvantage of it is more overhead of context switching. Description of the project: Code: Class // Java program for implementation of RR scheduling public class RR { // Method to find the waiting time for all // processes static void findWaitingTime(int processes[], int n, int bt[], int wt[], int quantum) { // Make a copy of burst times bt[] to store remaining // burst times. int rem_bt[] = new int[n]; for (int i = 0; i 0) { done = false; // There is a pending process if (rem_bt[i] > quantum) { // Increase the value of t i.e. shows 1/ how much time a process has been processed t += quantum; // Decrease the burst_time of current process // by quantum rem_bt[i] -= quantum; } // If burst time is smaller than or equal to // quantum.

You are given a 2-byte wide bus that supports single-byte, dual-word (same clock cycle) and burst transfers of up to eight bytes (four-byte pairs per burst). The overhead of each of these types of transfers is 1 clock cycle (O=1) and a data transfer takes one clock cycle per single or dual word (D=1). You want to send a 1080P video frame at a resolution of 1920×1080 pixels with three bytes per pixel. Compare the difference in bus transfer times if the pixels are packed vs. sending a pixel as a 2-byte followed by a single-byte transfer.

Answers

Given that a video frame of 1080P has a resolution of 1920 x 1080 pixels with three bytes per pixel. Therefore the total number of bytes for the frame is (1920 x 1080 x 3) bytes = 6220800 bytes.

The total number of transfers required for each case:Pixel packed: 6220800 / 2 bytes = 3110400 transfers.

6220800 / 8 bytes = 777600 transfers.

Single-byte transfer for third byte: 6220800 / 3 bytes = 2073600 transfers.

6220800 / 8 bytes = 777600 transfers.

Total transfer time for pixel packed: Single-byte transfers require O + D = 1 + 1 = 2 clock cycles per transfer.

3110400 x 2 clock cycles = 6220800 clock cycles.

Burst transfers require O + (D x 4) = 1 + 4 = 5 clock cycles per transfer.

777600 x 5 clock cycles = 3,888,000 clock cycles.

Total transfer time for a pixel packed transfer is 6220800 + 3888000 = 10,100,800 clock cycles.

Total transfer time for the single-byte transfer for the third byte:

Single-byte transfers require O + D = 1 + 1 = 2 clock cycles per transfer.

2073600 x 2 clock cycles = 4147200 clock cycles.

Burst transfers require O + (D x 4) = 1 + 4 = 5 clock cycles per transfer.

777600 x 5 clock cycles = 3,888,000 clock cycles.

Total transfer time for a single-byte transfer for the third byte is 4147200 + 3888000 = 8,036,200 clock cycles.

The difference in bus transfer times if the pixels are packed vs sending a pixel as a 2-byte followed by a single-byte transfer is 10,100,800 - 8,036,200 = 2,064,600 clock cycles. Therefore, pixel packed transfer is slower.

Why is linear programming generally preferred over non-linear programming when a problem may be formulated both ways?

Answers

linear programming is generally preferred over non-linear programming when a problem may be formulated both ways because it is easier to solve, computationally less expensive, has well-developed theory, and is widely used in practice.

Linear programming is generally preferred over non-linear programming when a problem may be formulated both ways due to the following reasons:

1. It is easier to solveLinear programming problems are generally easier to solve than non-linear programming problems. This is because linear programming problems can be solved with well-known and well-established algorithms. In contrast, non-linear programming problems require more complex optimization techniques to solve.

2. It is computationally less expensiveLinear programming is computationally less expensive than non-linear programming. This is because linear programming problems involve the optimization of a linear objective function subject to linear constraints, which can be solved using basic algebraic operations. In contrast, non-linear programming problems involve the optimization of a non-linear objective function subject to non-linear constraints, which require more complex computational algorithms

.3. It has well-developed theoryLinear programming has a well-developed theory that makes it easier to formulate and solve problems.

This theory includes the simplex method, duality theory, and sensitivity analysis, which provide a framework for solving linear programming problems. In contrast, non-linear programming does not have a well-developed theory, making it more difficult to formulate and solve problems.

4. It is widely used in practiceLinear programming is widely used in practice in many fields, including engineering, economics, and management science. This is because it is easy to model real-world problems as linear programming problems and because it has well-established applications in these fields.

Non-linear programming, in contrast, is less widely used in practice due to its complexity and lack of well-developed theory.

In conclusion, linear programming is generally preferred over non-linear programming when a problem may be formulated both ways because it is easier to solve, computationally less expensive, has well-developed theory, and is widely used in practice.

Given the following data file: (4 marks) EMPLOYEE(NAME, SSN, ADDRESS, JOB, SAL, ... ) Suppose that: record size R=1500 bytes block size B=5120 bytes r=300000 records For an index on the SSN field, assume the field size Vssn=15 bytes, assume the record pointer size Pr=10 bytes. If the file records are ordered, find the binary search cost step by steps.

Answers

Given the following data file: EMPLOYEE(NAME, SSN, ADDRESS, JOB, SAL, …)Suppose that:record size R=1500 bytesblock size B=5120 bytesr=300000 records

For an index on the SSN field, assume the field size Vssn=15 bytes, assume the record pointer size Pr=10 bytes.

If the file records are ordered, the binary search cost step by steps is explained below:

Step 1: For each block, there are b=R/r = 5120/1500=3.42 ≈ 3 records. Since the data records are sorted by SSN, the blocks are sorted by the values of the first SSN in each block.

Step 2: The number of blocks required to store the data file is the number of records in the data file divided by the number of records in a block: b= r/b=300000/3=100,000 blocks.

Step 3: The size of each index entry is the size of the SSN field plus the size of the record pointer: K=Vssn+Pr=15+10=25 bytes.

Step 4: The number of index entries that can fit in each index block is B/K = 5120/25 = 204.8 ≈ 204.

Step 5: The number of blocks required for the index is the number of entries in the index divided by the number of entries in a block: B = r/b = 100,000/204 = 490.2 ≈ 491 blocks.

Step 6: The cost of a binary search in the index is log2 (n) where n is the number of entries in the index. Since there are 204 entries per block, the total number of entries is 491 × 204 = 100,164. Therefore, the cost of a binary search is log2(100,164) = 16.66 ≈ 17 disk accesses.

The binary search cost is 17 disk accesses.
