A flat-panel detector is exposed with nothing between the x-ray tube and detector. 5 images were acquired on 5 different days using the same exposure. The pixel readings within a region of interest (ROI) are compared. What quality control test was performed?
a. Detectability
b. Linearity
c. Repeatability
d. Uniformity

Answers

Answer 1

Answer:

c. Repeatability

Explanation:

Since in the question it is mentioned that the falt panel detects the relation between the x-ray tube and detector. Also five images were purchased on five different days but used the similar exposure

So for the quality control test, the repeatability should be performed as the reading of the pixel is done within a region of interest also it examines the consistency of the pixel reading over time

Hence, the correct option is c.

How do I make my kali Linux faster in my virtual box?

Answers

Answer:

If you run any operating system as a VM, it is going to be slower than if you were to run it as a native OS. You can, however, make a VM run faster by allocating more CPU cores and RAM to it in your hypervisor's (such as Virtualbox or VMWare) settings menu for your VM.

does that make sense?

What VM are you using? if your using virual box then try adding more RAM to it. I use VMware player 16 and its REALLY fast so try that. Also, go on online and look up this guy called network chuck.

How I to turn this ''loop while'' in ''loop for''? var i = 0; while (i < 20) { var lineY = 20 + (i * 20); line(0, lineY, 400, lineY); i++; }

Answers

Answer:

for(i = 0; i<20;i++){

lineY = 20 + (i * 20);

line(0, lineY, 400, lineY) }

Explanation:

First declare and initialize the variable i. You have not specified the data type of i so if the data type of i is integer i.e. int then you should declare i variable in the for loop as for(int i = 0; i<20;i++)

So the given while loop has a variable i which is initialized to 0. Then while(i<20) means that while loop executes until the value of i exceeds 20. If this while condition is true then the two statements inside its body will execute. The two statements are: lineY = 20 + (i * 20);

line(0, lineY, 400, lineY);

The value of i ins incremented after each iteration i.e. i++

So while loop has the following syntax"

1) initialization;  ---->  i = 0

2) while(condition) {  ----> i<20

3) loop body ----->  lineY = 20 + (i * 20); line(0, lineY, 400, lineY);

4) increment or decrement loop variable  } ----> i++

For loop has the following syntax:

for( initialization of loop variable ; condition; decrement/increment loop variable)  {

loop body }

Here:

initialization  ---->  i = 0

condition        ----> i<20

loop body     -----> lineY = 20 + (i * 20); line(0, lineY, 400, lineY);

increment or decrement loop variable  ---->  i++

Answers

Answer:

The answer is "Option c".

Explanation:

In Java programming, the API stands for "application programming interface", which is also known as the lists of all classes in the JDK. It contains all packages, classes, and interfaces, with their techniques, fields. It is a built-in class, which gives the programmer a great deal of usability, and correct choices can be described as follows:

In option a, It is correct because it imports the package to use API. In option b, It allows you to "re-invent the wheel" by developers, that's why it is correct.

Answer:

In the classified section of a local newspaper, I came across job openings for the post of a network engineer in two different companies. One was from the airline industry, while the other was from the food and beverage industry.

The airline company required an applicant to have a bachelor's degree in network administration. The job posting specified that applicants with supporting CCENT or CompTIA Security+ certifications would be preferred. The company was willing to consider candidates with no prior experience. The job responsibilities included: maintaining security, DNS, IP routing, firewalls, and troubleshooting IT-related problems. The role also required skills to manage multi-site network operations, operating systems, and other software applications in public as well as private facilities. Another responsibility was to complete the time logs in the company's records to facilitate timely and accurate billing.

For the role of a network engineer in the food and beverage industry, the required qualification was any bachelor's degree in computer science with a minimum of one year of relevant experience. Certifications were an added advantage, but they were not a necessity. The job role required skills to troubleshoot network glitches, monitor network usage, install software and hardware infrastructure, provide technical assistance to users, and suggest improvements in the system.

if a person walks 10 metres due to south in 10 seconds 10 due east in the next 10 seconds and transmitted you're not in the next 10 seconds then he has Dash velocity​

Answers

Answer:

[tex]\frac{1}{3}\ m/s[/tex]

Explanation:

The computation of the velocity by using the following formula is

As we know that

[tex]Velocity = \frac{Displacement}{Total\ time\ taken}[/tex]

where,

Displacement is 10 meters

Total time taken is 30 seconds

Now placing these values to the above formula

So, the velocity of Dash is

[tex]= \frac{10\ meters}{30\ seconds}[/tex]

[tex]= \frac{1}{3}\ m/s[/tex]

We simply applied the above formula so that we can get the velocity and the same is to be considered

A systems administrator is designing a directory architecture to support Linux servers using Lightweight Directory Access Protocol (LDAP). The directory needs to be able to make changes to directory objects securely. Which of these common operations supports these requirements?

Answers

The options available are:

Search, modify.

StartTLS, delete.

Bind, modify.

Bind, add.

Answer:

StartTLS, delete

Explanation:

StartTLS is a computer networking term for email protocol command, in which a system administrator buses it to command an email server that an email client running in a web browser, wants to turn an existing insecure connection into a secure one. Thus, during this process, StartTLS permits a client to communicate securely using LDAPv3 over TLS.

On the other hand, the DELETE operation can make a change to a directory object.

According to the given question, the common operations that supports requirements where directory needs to be able to make changes to directory objects securely are;

Bind, addSearch, modifyBind, modifyStartTLS, delet

According to the question, we are to discuss the common operations that supports some requirements as regards the changing of directory objects securely.

As a result of this we can see that making use of  StartTLS, delete can serve this purpose and other function as well.

Therefore, common operations that supports requirements where directory needs to be able to make changes to directory objects securely is Search and modify.

Answers

Answer:

Following are the code to this question:

def binarynumber(num):#defining a method binarynumber that accepts a parameter num

   x=""#defining a string variable x

   if (num!=0):#defining if condition to check number not equal to 0

       while (num>=1):#defining a loop that check value is grater then equal to one

           if (num %2==0):#defining if condition to check num is even

               x=x+"0" #add string value 0 in num variable

               num=num/2 #divide the value by 2

           else:#defining else block

               x=x+"1"#add string value 1 in num variable

               num=(num-1)/2#first subtract 1 into num variable then divide the value by 2

   else:

       x="0"#assign string value 0 in num variable  

   return "".join(reversed(x))#return value

num = int (input ("Enter any number: "))#defining num variable that input the integer value

print (binarynumber(num))#using print method to call method binarynumber with passing num parameter

Output:

Enter any number: 12

1100

Explanation:

In the above python code a method "binarynumber" is declared, in which the "num" variable passes as the parameter inside the method a string variable "x" is declared that stores all converted values. Inside the method and if the block is declared that checks number value is not equal to 0 if this condition is false then it will add string value and reverse its value. Or if the condition is true it defines a while loop that calculates the given number binary digits and returns its value. At the last step, the num variable is declared that inputs the integer value from the user end and calls the method by using the print method.
