Bridge Measurement
The sensitivity of a sensor can be increased by incorporating it in a bridge arrangement. Impedance varying sensors are often arranged in DC or AC Wheatstone bridges. In some types…
The Binary Search Algorithm
All right, so you've read about sorting algorithms, and now you've got a sorted array. Just having a sorted array, however, doesn't do anything for you unless you are going…
Data Trees: Introduction
It is recommended that you read the essay on linked lists before proceeding to this essay. Trees are data structures organized into a group of interconnected nodes that form leaves…
Sorting Algorithms: Introduction
Sorting has been analyzed by computer scientists for decades, and thus it is an ideal subject to begin with when studying computer science. Sorting is done with algorithms, which are…
Lists and Arrays: Introduction
Lists and Array are the most basic types of data structures. They allow the programmer to organize data into more sophisticated patterns than the simple variables would allow. Almost all…
Recursion and Iteration
Recursion and iteration are two very commonly used, powerful methods of solving complex problems, directly harnessing the power of the computer to calculate things very quickly. Both methods rely on…
The Space-Time Continuum
Algorithms like Quicksort and Mergesort are exceedingly fast, but require lots of space to do the operations. On the other side of the spectrum, Bubble Sort is exceedingly slow, but…
Converting from decimal to octal or hexadecimal
It turns out that when you wish to convert from decimal to octal or hexadecimal, there is a very easy formula that you can use. I'll give you the one…
