Answer:

THREE strategies which local municipality is implementing in addressing the issue of lack of clean water caused by human factors include:

1) Increasing the amount of tax for those companies which are opening their wastes into water sources which can help built better water cleaning and recycle system.

2) Tree plantation is another strategy to help secure the water sources and naturally keep cleaning it.

3) Running awareness campaigns for general people to keep the water sources clean as well as use the only amount of water which they need and not waste it.

Suppose you have two arrays of ints, arr1 and arr2, each containing ints that are sorted in ascending order. Write a static meth

telo118 [61]

Since both arrays are already sorted, that means that the first int of one of the arrays will be smaller than all the ints that come after it in the same array. We also know that if the first int of arr1 is smaller than the first int of arr2, then by the same logic, the first int of arr1 is smaller than all the ints in arr2 since arr2 is also sorted.

public static int[] merge(int[] arr1, int[] arr2) {
int i = 0; //current index of arr1
int j = 0; //current index of arr2
int[] result = new int[arr1.length+arr2.length]
while(i < arr1.length && j < arr2.length) {
result[i+j] = Math.min(arr1[i], arr2[j]);
if(arr1[i] < arr2[j]) {
i++;
} else {
j++;
}
}
boolean isArr1 = i+1 < arr1.length;
for(int index = isArr1 ? i : j; index < isArr1 ? arr1.length : arr2.length; index++) {
result[i+j+index] = isArr1 ? arr1[index] : arr2[index]
}
return result;
}

So this implementation is kind of confusing, but it's the first way I thought to do it so I ran with it. There is probably an easier way, but that's the beauty of programming.

A quick explanation:

We first loop through the arrays comparing the first elements of each array, adding whichever is the smallest to the result array. Each time we do so, we increment the index value (i or j) for the array that had the smaller number. Now the next time we are comparing the NEXT element in that array to the PREVIOUS element of the other array. We do this until we reach the end of either arr1 or arr2 so that we don't get an out of bounds exception.

The second step in our method is to tack on the remaining integers to the resulting array. We need to do this because when we reach the end of one array, there will still be at least one more integer in the other array. The boolean isArr1 is telling us whether arr1 is the array with leftovers. If so, we loop through the remaining indices of arr1 and add them to the result. Otherwise, we do the same for arr2. All of this is done using ternary operations to determine which array to use, but if we wanted to we could split the code into two for loops using an if statement.

How to calculate a pid controller

pishuonlain [190]

Answer:

Control by PID1

is a control method often used for servos.

Don't you know what a bondage is? Well, it's a system, capable of reaching and

maintain a setpoint thanks to the measurements it performs.

Imagine, for example, in a car on the highway. You want to drive at 130Km / h

without having to press the accelerator. Your car's cruise control should

by itself maintain this speed. When approaching a slope the system "notices" that for

the same power at the level of the motor, it no longer reaches the 130 km / h setpoint and will add a

little acceleration. Yes but by how much? And how long will it take for the system to

stabilize around the setpoint?

That's the whole servo problem and PID control is one way to solve it!

PID is the most widely used regulator in industry. The idea of this control body is to

intentionally modify the value of the error which remains between the setpoint and the measurement

performed.

For example in the case of a position control the error would be: ε = c (p) - s (p)

In the case of proportional control, the error is virtually amplified by a certain gain

constant that should be determined according to the system.

Setpoint (t) = Kp.ε (t)

What in Laplace gives:

Setpoint (p) = Kp.ε (p)

Answer:

A. True

Explanation:

Be sure your processor is receiving sufficient cooling by verifying if there is a heatsink on it. If there is, make sure that it's inserted fully into cpu_fan port on the motherboard. If the boot process still turns off, you may have a defective processor or replace the motherboard.
