State diagram for a turnstile A turnstile. An example of a simple mechanism that can be modeled by a state machine is a turnstile. [4] [5] A turnstile, used to control access to subways and amusement park rides, is a gate with three rotating arms at waist height, one across the entryway.
As a consequence, the same is true of the inclusion problem, i.e., given two NFAs, is the language of one a subset of the language of the other. Given as input an NFA A and an integer n, the counting problem of determining how many words of length n are accepted by A is intractable; it is #P-hard.
AVMs are increasingly used by mortgage lenders to determine what a property might be worth in order for them to lend against the valuation. The advantages of using AVMs over traditional appraisals are that they save time, money and resources (e.g. there are no transport requirements), thus lowering the cost of valuing a property.
An example of a deterministic finite automaton that accepts only binary numbers that are multiples of 3. The state S 0 is both the start state and an accept state. For example, the string "1001" leads to the state sequence S 0, S 1, S 2, S 1, S 0, and is hence accepted.
Formally, a deterministic Büchi automaton is a tuple A = (Q,Σ,δ,q 0,F) that consists of the following components: . Q is a finite set.The elements of Q are called the states of A.
Fuzzy logic is an attempt to apply the easy design of logic controllers to the control of complex continuously varying systems. Basically, a measurement in a fuzzy logic system can be partly true. The rules of the system are written in natural language and translated into fuzzy logic.

Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building ...
