Which branch of science helps avoid or minimize stress related injuries at workplace? _____ is a branch of science that aims to

QveST [7]

Answer:

Ergonomics

Explanation:

We can get stress injuries in the workplace, and the study of the stress injuries at workplaces is a very important branch of scientific study currently, and all companies from all the fields are working on it, and so are the academic and research institutions. And this branch has gained heights in the past 10 years as companies want to increase worker productivity as well as bring down the downtime as well as various injury claims related to the job. And we know this branch as "ergonomics".

What is an Algorithm? (might not be in the chapter text). Give an example.

Rashid [163]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

An algorithm is the list of a finite set of instructions and rules that a computer needs to do to complete a task in order to solve a problem.

In short, an algorithm is a series of instructions that are implemented step by step to solve a problem. For example, you could consider a pizza recipe an algorithm for making a pizza in an everyday life routine. But when you are talking about using algorithms in computation and in mathematics. It means that solving a problem using a series of steps step by step.

For example, your everyday tasks aligned on a google calendar and remind you about your tasks using the alarm, etc- how to implement this using set of instructions and rules- is an algorithm.

Solving a quadratic equation is another example of an algorithm.

Binary search, array sorting are an example of an algorithm in computation. Because these algorithms based on the execution of step-by-step instruction to solve a problem such as sorting a list of numbers etc.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer

oksano4ka [1.4K]

Answer:

The program in Python is as follows:

def get_user_values():

user_values = []

n = int(input())

for i in range(n+1):

inp = int(input())

user_values.append(inp)

output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

for i in user_values:

if i <= upper_threshold:

print(i,end=" ")

get_user_values()

Explanation:

This defins the get_user_values() method; it receives no parameter

def get_user_values():

This initializes user_values list

user_values = []

This gets the number of inputs

n = int(input())

This loop is repeated n+1 times to get all inputs and the upper threshold

for i in range(n+1):

inp = int(input())

user_values.append(inp)

This passes the list and the upper threshold to the output..... list output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

This defines the output.... list

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through the list

for i in user_values:

If current element is less or equal to the upper threshold, the element is printed

if i <= upper_threshold:

print(i,end=" ")

The main method begins here where the get_user_values() method is called

get_user_values()

Convert infix to postfix

kvv77 [185]

Answer:

static int checkSymbol(char ch)

{

switch (ch)

{

case '+':

case '-':

return 1;

case '*':

case '/':

return 2;

case '^':

return 3;

}

return -1;

}

static String convertInfixToPostfix(String expression)

{

String calculation = new String("");

Stack<Character> operands = new Stack<>();

Stack<Character> operators = new Stack<>();

for (int i = 0; i<expression.length(); ++i)

{

char c = expression.charAt(i);

if (Character.isLetterOrDigit(c))

operands.push(c);

else if (c == '(')

operators.push(c);

else if (c == ')')

{

while (!operators.isEmpty() && operators.peek() != '(')

operands.push(operators.pop());

if (!operators.isEmpty() && operators.peek() != '(')

return NULL;

else

operators.pop();

}

else

{

while (!operators.isEmpty() && checkSymbol(c) <= checkSymbol(operators.peek()))

operands.push(operators.pop());

operators.push(c);

}

while (!operators.isEmpty())

operands.push(operators.pop());

while (!operands.isEmpty())

calculation+=operands.pop();

calculation=calculation.reverse();

return calculation;

}

Explanation:

Create the checkSymbol function to see what symbol is being passed to the stack.
Create the convertInfixToPostfix function that keeps track of the operands and the operators stack.
Use conditional statements to check whether the character being passed is a letter, digit, symbol or a bracket.
While the operators is not empty, keep pushing the character to the operators stack.
At last reverse and return the calculation which has all the results.
