Quizlet was founded in 2005 by Andrew Sutherland as a studying tool to aid in memorization for his French class, which he claimed to have "aced". [6] [7] [8] Quizlet's blog, written mostly by Andrew in the earlier days of the company, claims it had reached 50,000 registered users in 252 days online. [9]
Real-time simulators are used extensively in many engineering fields. As a result, the inclusion of simulation applications in academic curricula can provide great value to the student. Statistical power grid protection tests, aircraft design and simulation, motor drive controller design methods and space robot integration are a few examples of ...
Just as the class P is defined in terms of polynomial running time, the class EXPTIME is the set of all decision problems that have exponential running time. In other words, any problem in EXPTIME is solvable by a deterministic Turing machine in O (2 p ( n ) ) time, where p ( n ) is a polynomial function of n .
A system is said to be real-time if the total correctness of an operation depends not only upon its logical correctness, but also upon the time in which it is performed. [5] Real-time systems, as well as their deadlines, are classified by the consequence of missing a deadline: [6] Hard – missing a deadline is a total system failure.
Numerical analysis is the study of algorithms that use numerical approximation (as opposed to general symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). [25] Modern numerical analysis does not seek exact answers, because exact answers are often impossible to obtain in practice.
A flashcard or flash card is a card bearing information on both sides, usually intended to practice and/or aid memorization. It can be virtual (part of a flashcard software ) or physical. Typically, each flashcard bears a question or definition on one side and an answer or target term on the other.
The systems studied in chaos theory are deterministic. If the initial state were known exactly, then the future state of such a system could theoretically be predicted. However, in practice, knowledge about the future state is limited by the precision with which the initial state can be measured, and chaotic systems are characterized by a strong dependence on the initial condit
A group of students preparing for a test. Test preparation (abbreviated test prep) or exam preparation is an educational course, tutoring service, educational material, or a learning tool designed to increase students' performance on standardized tests.
