What's the endianness of a computing system? (7 point)"
The endianness of a computing system refers to the order in which the bytes of a multi-byte data type are stored in memory.
It determines whether the most significant byte (MSB) or the least significant byte (LSB) of a data type is stored at the lowest memory address. There are two common types of endianness: Big Endian and Little Endian.
In a Big Endian system, the MSB is stored at the lowest memory address, while the LSB is stored at the highest memory address. This means that the bytes are ordered from left to right, similar to how we write decimal numbers. On the other hand, in a Little Endian system, the LSB is stored at the lowest memory address, and the MSB is stored at the highest memory address. The bytes are ordered from right to left.
The choice of endianness is determined by the computer architecture and the underlying hardware. Different processors and systems may use different endianness. For example, the x86 architecture commonly uses Little Endian, while some network protocols use Big Endian for consistency.
The endianness of a system is important when data is transferred between different systems or when binary data is read or written. It is crucial to ensure that the endianness is correctly interpreted to avoid data corruption or incorrect results.

Please do not answer whit copy pasted answer from similar question,
I will report those who does this ! 2. Let p be a prime number of length k bits. Let H(x) = x² (mod p) be a hash function which maps any message to a k-bit hash value.
(c) Is this function collision resistant? Why?
The hash function H(x) = x² (mod p) is not collision resistant for prime numbers of length k bits.
Collision resistance means that it is computationally infeasible to find two different inputs that produce the same hash output. In the given hash function, H(x) = x² (mod p), the output is determined by squaring the input and taking the result modulo p.
However, this function is not collision resistant because for any input x, there exists another input -x (mod p) that produces the same hash output. This is because (-x)² (mod p) is congruent to x² (mod p) due to the properties of modular arithmetic. Therefore, we have found two different inputs (x and -x) that produce the same hash output, violating the property of collision resistance.
In other words, this hash function fails to provide the desired level of security since an attacker can easily find collisions by negating the input value. To achieve collision resistance, a hash function should not have such trivial collisions, and different inputs should produce different hash outputs.

(b) It is desired to dry a certain type of fiber board in sheets 0.131 m length, 0.162 m breadth and 0.071 m thickness from 58% to 5% moisture( wet basis ) content. Initially from laboratory test data with this fiber board, the rate of drying at the critical moisture content was found to be 9.9 kg/m²hr at the constant drying period. The critical moisture content was 24.9 % and the equilibrium moisture content was 1 %. The fiber board has to be dried on one side only and it has a density (dry basis) of 2310 kg/m³. Determine the Time required for drying.
The time required for drying is 4.97 hours (approx).
B(a) Moisture content in a wet solid undergoing the drying processThe different states of moisture content in a wet solid undergoing the drying process are as follows:Free moisture content: It is the moisture which gets evaporated easily and is seen on the surface of the solid.Capillary moisture content: It is the moisture which is held in the capillary pores of the solid.Hygroscopic moisture content: It is the moisture which is held by the solid through adsorption and it is bound tightly to the surface of the solid.

Match the following statements about DC power supplies to the correct concepts: Transform an alternating current into a current that flows in only one direction ✓ [Choose ] Stability of the output voltage with variation in the unregulated input voltage The output voltage varies slightly when you connect the supply to a circuit Line regulation Rectification Load regulation [Choose ]
Transform an alternating current into a current that flows in only one direction: Rectification Stability of the output voltage with variation in the unregulated input voltage: Line regulation
Rectification: DC power supplies are used to transform alternating current (AC) into a current that flows in only one direction, which is direct current (DC). This is achieved through the process of rectification, which involves converting the AC waveform into a continuous DC waveform.
Line regulation: Line regulation refers to the ability of a DC power supply to maintain a stable output voltage despite variations in the unregulated input voltage. It ensures that the output voltage remains constant within a specified range, even when there are fluctuations or changes in the input voltage from the power source.
Load regulation: Load regulation refers to the ability of a DC power supply to maintain a stable output voltage when it is connected to a load or circuit. It ensures that the output voltage does not vary significantly as the load current changes. A well-regulated power supply will exhibit minimal variations in output voltage when subjected to different load conditions.
To match the statements to the concepts:
"Transform an alternating current into a current that flows in only one direction" corresponds to Rectification.
"Stability of the output voltage with variation in the unregulated input voltage" corresponds to Line regulation.
"The output voltage varies slightly when you connect the supply to a circuit" corresponds to Load regulation.

Answer : a) U2 = -22.4 V
b) P = 0.54 W
Explanation :
a) Value of U2 by using mesh-current analysis:The given circuit is shown below:
Given data are R1 = 12Ω R2 = 272Ω R3 = 122Ω R4 = 30.12Ω Rs = 512Ω R6 = 612Ω 12V voltage source U2 = ?
We can determine the value of U2 by using mesh-current analysis.
Let I1 is flowing through R1, R2, R3, and I2 is flowing through R2, R4, Rs, R6.
Loop 1: 12 + I1R1 + I2R3 - I1R2 = 0
Loop 2: I2Rs + I2R4 - I1R2 = 0
Solving the above two equations, we get;
I1 = 0.0447 AI2 = 0.1271 A
Therefore, the current flowing through R2 is 0.0447 - 0.1271 = -0.0824 A (i.e. opposite direction to I2).
U2 = -0.0824 × 272 = -22.4 V
Ans: U2 = -22.4 V
b) Power delivered by the source:
We can determine the power delivered by the source by using the formula:
P = V × ITotal Where V is the voltage across the source and ITotal is the current flowing through the source.
The total current flowing through the source = I1 = 0.0447 A
Voltage across the source = 12 V
Therefore,Power delivered by the source = 12 × 0.0447 = 0.54 W

Its steps are: my 1) Soaping, 2) Washing, 3) Drying A F M2, P2 RI During the first step of Soaping, the controller operates the pump to apply soap. Once the fixed time is completed, the second step is the washing car. The pump is activated for this purpose and one motor operates a brush to scrub the car with soap. The next step is to dry the car and for that let us use the fix-time again. The fan will be activated for drying purposes. Finally, the conveyor belt takes the car to the end exit. As soon as the limit switch detects the Car at the end, the Car washing process is completed. Put additional manual on/off buttons to stop or turn it on, when required. 1. Explain the logic sequence of Automatic Car Washing, by steps or by a flow chart. 2. Write the PIC C code with the comment on each instruction. 3. Draw an interfacing diagram or block diagram of all required components for the above objective.
The logic sequence of the automatic car washing system can be represented using a flow chart. Here is an explanation of the logic sequence step by step:
Step 1: Car Detection
Check if a car is present on the conveyor belt.
If a car is detected, proceed to the next step. Otherwise, wait for a car to arrive.
Step 2: Soaping
To wash the automobile with soap, turn on the soap pump.
Start a timer for the fixed soap application time.
Continue applying soap until the timer expires.
Step 3: Washing
Activate the brush motor to scrub the car with soap.
Ensure the brush motor operates for the desired washing time.
Continue washing until the washing time is completed.
Step 4: Drying
Activate the fan for drying the car.
Start a timer for the fixed drying time.
Continue drying until the timer expires.
Step 5: Car Exit
Check if the limit switch detects the car at the end of the conveyor belt.
If the car is detected, the car washing process is completed.
If the car is not detected, return to Step 1 to await the next car.
PIC C Code:
Here is an example of PIC C code with comments for the automatic car washing system:
// Include necessary libraries and define pin connections
void main() {
// Initialize the system
while (1) {
// Car Detection
if (carDetected()) {
// Soaping
activateSoapPump();
startSoapTimer();
while (!soapTimerExpired()) {

while (!dryTimerExpired()) {
continueDrying();
}
// Car Exit
if (carAtEnd()) {
// Car washing process completed
break;
}
}
}
// Turn off all components and end the program
}
Interfacing Diagram/Block Diagram:
An interfacing diagram or block diagram of the required components for the automatic car washing system would include components such as a car detection sensor, soap pump, brush motor, fan, limit switch, conveyor belt, timers, and on/off buttons.

The MATLAB code below calculates and prints the squares of all the even integers between 0 and 50, displaying them in a table format with labeled columns.
To calculate and print the squares of even integers, we can use a loop and the fprintf function in MATLAB. The loop iterates over the even integers between 0 and 50, and for each even number, it calculates its square and prints it along with the original number using the fprintf function.fprintf('Number\tSquare\n'); % Print column labels
for num = 0:2:50 % Iterate over even numbers
square = num^2; % Calculate square
fprintf('%d\t%d\n', num, square); % Print number and its square
end
The fprintf function is used to format and print text. In this case, we use it to print the number and its square in a table format, with each value separated by a tab. The %d format specifier is used to represent integers.
The loop starts from 0 and increments by 2 in each iteration, ensuring that only even numbers are considered. The square of each even number is calculated using the exponentiation operator ^. The fprintf function is then used to print the number and its square, separated by a tab, for each iteration of the loop.

Which of the following is the correct statement? a. An array is passed to a method by passing the array's values b. A method cannot modify the elements of an array argument c. An array is converted to another data type and passed to a method d. An array is passed to a method by passing a reference to the array
The correct statement is d. An array is passed to a method by passing a reference to the array.
In most programming languages, including Java and C++, when an array is passed as an argument to a method, it is not the actual values of the array that are passed, but rather a reference to the memory location where the array is stored. This reference allows the method to access and modify the elements of the array.
By passing a reference to the array, any changes made to the array elements within the method will be reflected in the original array outside the method. This is because both the original array and the method's local copy refer to the same memory location.
Therefore, when working with arrays in methods, modifications to the array elements can be done directly, and these modifications will be visible outside the method. This is in contrast to passing by value, where a copy of the value is passed, and modifications made to the parameter inside the method do not affect the original value.
Passing arrays by reference allows for efficient memory usage and enables the method to work with the actual array data, making it a common and effective approach for working with arrays in many programming languages.

If the TEOS flow rate is increased in a PECVD TEOS oxide deposition process, what are the effects on the deposition rate, refractive index, and film stress? Explain
If the TEOS flow rate is increased in a PECVD TEOS oxide deposition process, there would be effects on the deposition rate, refractive index, and film stress.
When the TEOS flow rate is increased, there would be an increase in the deposition rate. This is because the amount of TEOS available for reaction with the plasma species would be higher.Refractive index:The refractive index of the deposited SiO2 film is a measure of its optical density.
An increase in the TEOS flow rate would lead to an increase in the film thickness, which in turn would result in an increase in the refractive index. This is because the optical path length of the light through the film would be longer.

Sonar Kit
You must create a class to represent a Sonar Kit. If the Iceman picks up a Sonar Kit, he can
use it to scan the oil field at a later time to locate buried Gold Nuggets and Barrels of oil.
Here are the requirements you must meet when implementing the Sonar Kit class.
What a Sonar Kit object Must Do When It Is Created
When it is first created:
1. All Sonar Kits must have an image ID of IID_SONAR. 2. All Sonar Kits must have their x,y location specified for them when they are
created.
3. All Sonar Kits must start off facing rightward.
4. All Sonar Kits starts out visible.
5. A Sonar Kit is only pickup-able by the Iceman.
6. A Sonar Kit will always start out in a temporary state (where they will only
remain in the oil field for a limited number of ticks before disappearing) – the
number of ticks T a Sonar Kit will exist can be determined from the following
formula:
T = max(100, 300 – 10*current_level_number)
37
7. Sonar Kits have the following graphic parameters: a. They have an image depth of 2 – behind actors like Protesters, but above
Ice
b. They have a size of 1.0
In addition to any other initialization that you decide to do in your Sonar Kit class, a
Sonar Kit object must set itself to be visible using the GraphObject class’s setVisible()
method, e.g.:
setVisible(true);
What the Sonar Kit Object Must Do During a Tick
Each time the Sonar Kit object is asked to do something (during a tick):
1. The object must check to see if it is currently alive. If not, then its doSomething()
method must return immediately – none of the following steps should be performed.
2. Otherwise, if the Sonar Kit is within a radius of 3.0 (<= 3.00 units away) from the
Iceman, then the Sonar Kit will activate, and:
a. The Sonar Kit must set its state to dead (so that it will be removed by your
StudentWorld class from the game at the end of the current tick).
b. The Sonar Kit must play a sound effect to indicate that the Iceman picked up
the Goodie: SOUND_GOT_GOODIE. c. The Sonar Kit must tell the Iceman object that it just received a new Sonar Kit
so it can update its inventory.
d. The Sonar Kit increases the player’s score by 75 points (This increase can be
performed by the Iceman class or the Sonar Kit class).
3. Since the Sonar Kit is always in a temporary state, it will check to see if its tick
lifetime has elapsed, and if so it must set its state to dead (so that it will be removed
by your StudentWorld class from the game at the end of the current tick).
What an Sonar Kit Must Do When It Is Annoyed
Sonar Kits can’t be annoyed and will not block Squirts from the Iceman’s squirt gun.
Additionally, the Sonar Kit checks if its lifetime has elapsed. If it has, it sets its state to dead. This ensures that the Sonar Kit will be removed from the game after its limited lifetime expires.
The Sonar Kit class represents an object in the game that can be picked up by the Iceman character. The Sonar Kit has specific initialization requirements, including its image ID, location, initial facing direction, visibility, and limited lifetime. During each game tick, the Sonar Kit checks if it is alive and activates if it is within a certain distance from the Iceman.
When activated, it plays a sound effect, updates the Iceman's inventory, increases the player's score, and sets its state to dead. Additionally, the Sonar Kit checks if its lifetime has elapsed and sets its state to dead if necessary. Sonar Kits cannot be annoyed and do not block the Iceman's squirt gun.
The Sonar Kit class is designed to encapsulate the behavior and properties of a Sonar Kit object in the game. When a Sonar Kit is created, it is initialized with specific attributes such as the image ID, location, facing direction, visibility, and lifetime. The lifetime of the Sonar Kit is determined by a formula based on the current level number.
During each game tick, the Sonar Kit's doSomething() method is called. It first checks if the Sonar Kit is alive. If it's not alive, it immediately returns. Otherwise, it checks if it is within a certain distance from the Iceman. If the condition is met, the Sonar Kit activates by setting its state to dead, playing a sound effect, notifying the Iceman, and increasing the player's score.
It's worth noting that Sonar Kits cannot be annoyed, and they do not block the Iceman's squirt gun, meaning they have no effect on the game mechanics related to annoying or blocking actions.

The cheapest way to detect curbs in autonomous vehicle, what sensor can be used.
Group of answer choices
IMU sensor
Lidar sensor
Radar sensor
GPS
Ultrasonic sensor
The cheapest sensor option among the provided choices for detecting curbs in an autonomous vehicle would be an Ultrasonic sensor.
Ultrasonic sensors use sound waves to detect objects and measure distances. They emit high-frequency sound waves and measure the time it takes for the waves to bounce back after hitting an object. This information can be used to determine the distance between the sensor and the object.
Ultrasonic sensors are relatively inexpensive compared to other sensors like Lidar or Radar. They are commonly used in parking assistance systems and proximity sensors in autonomous vehicles.
While Ultrasonic sensors are cost-effective, it's important to note that they have some limitations. They may not provide the same level of accuracy or range as more advanced sensors like Lidar or Radar. Additionally, their performance can be affected by environmental conditions such as rain or dust.
For more precise curb detection or in scenarios where higher accuracy and range are required, Lidar or Radar sensors would be better options despite their higher cost. However, if the primary concern is cost and the requirements are not overly demanding, Ultrasonic sensors can provide a reasonable solution for curb detection in autonomous vehicles.

A company needs 55% by mass Decanol to manufacture a new product. The Decanol is obtained from evaporating a process stream, containing 15% Decanol by mass in a single stage evaporator. The feed stream to the evaporator has a flow rate of 1000 kg/h and temperature of 30°C. Saturated steam in the evaporator is available at 300 kPa and the vapour space in the evaporator is at 90 kPa. Determine: 2.1. The steam requirements. 2.2. The overall heat transfer coefficient.
The steam requirement is 1060.34 kg/h and the overall heat transfer coefficient is 1579.48 W/m².K.
The steam requirements for the given process can be calculated as follows:
Q = (Mass flow rate of the feed stream to the evaporator * Specific heat of the feed stream) + (Mass flow rate of the steam * Specific heat of the steam)
Where, Q = Total heat to be removed from the feed streamSpecific heat of the feed stream = 4.2 kJ/kg.K (assumed to be water)
μc = 0.00001599 Pa.s from steam tables.
Pr = (0.00001599*4.16)/(0.162) = 0.0004147Re = (1060.34/3600) * (0.025/0.00001599) = 2119.2
From the equation of Nusselt number,
Nu = [tex]0.027 * 2119.2^{0.8} * 0.0004147^{0.4[/tex]
= 29.14hd
= Nu * k / D = 29.14 * 0.0182 / 0.025 = 21.23W/m².K
The heat transfer coefficient of the feed side (hi) can be calculated using the following equation:
[tex]hi = (hio * hir^2) / (hir^2 + (Do/Di)*(hio-hir)^2)[/tex]
where,
hio = heat transfer coefficient of the internal side of the evaporator tube = 750 W/m².K (assumed)
hir = heat transfer coefficient of the internal side of the vapor space = 2000 W/m².K (assumed)
Do = Outside diameter of the evaporator tube = assumed to be 0.028 m
Di = Internal diameter of the evaporator tube = assumed to be 0.025 m
hi = [tex](750 * 2000^2) / (2000^2 + (0.028/0.025)*(750-2000)^2) = 1307.45 W/m².K[/tex]
The thickness of the film on the feed side (hf) can be taken as 0.001 m (assumed).The fouling resistances on both sides can be neglected as the process is operated only for a short duration. Hence, Rf = Rsat = 0.Overall heat transfer coefficient (U) can be calculated now as:
1/U = 1/1307.45 + 0.15*(0.162/0.001) + 0.85*(0.0182/0.001) + 0.15*0.85*0*0.12664/(0.001)
U = 1579.48 W/m².K

The conversion of four decimal numbers to 8-bit two's complement binary. However, it's important to note that the requested values exceed the range of 8-bit two's complement representation, which can only accommodate numbers from -128 to 127.
Two's complement binary notation is a method used to represent both positive and negative integers in binary form. However, 8-bit two's complement can only represent integers from -128 to 127. The given values, -48, 65, -75, and 82, all fall within this range, but if the values were in tens place (i.e. -4810, 6510, -7510, 8210), they would exceed the range and would not be representable in 8-bit two's complement. Two's complement is a mathematical operation on binary numbers. It's widely used in computing as a method of representing positive and negative integers. This system allows for easy binary arithmetic and negation, as the two's complement of a number negates it.
