Fuzzy logic is a form of logic that accounts for partial truth and vagueness. It is used in applications like ABS brakes, control units, and air conditioners. A fuzzy logic system defines membership functions that assign a degree of truth between 0 and 1 to inputs and uses a rules and inference mechanism to map inputs to outputs. For example, a fuzzy air conditioner controller defines membership functions for temperature inputs like "cold" and outputs like "stop" or "fast", and uses rules like "if cold then stop" to determine the fan speed based on the temperature.
WiMAX (IEEE 802.16) provides wireless broadband access over long distances using base stations. It supports high-speed Internet access without wires for home and business subscribers. WiMAX uses centralized control and supports applications with different quality of service needs. The physical layer allows directional antennas and uses frequency or time duplexing. The media access control layer uses connections, maps uplink and downlink channels, and supports scheduling services like unsolicited grant service for real-time traffic.

Candi Productions was chosen as the production company because they specialize in low-budget films and helping promote student work. All3media was selected as the distribution company as they are a major global distributor of television shows in the UK like Hollyoaks and Skins, which attract large teenage audiences, fitting the target audience of the thriller film. As a major distributor of British content, All3media would be well-suited to distribute the thriller filmed in the UK to British and young audiences across various platforms like YouTube and Facebook.
This document describes the design of a finite state machine (FSM) to control a simple washing machine. The washing machine has six states: off, fill water 1, drain 1, fill water 2, rinse, and drain 2. The FSM will use three D flip-flops to represent the three state bits and control the water, drum motor speed, and other functions. Boolean logic equations are provided for the D flip-flop inputs and outputs, as well as the control signals to the washing machine components. Block and state diagrams are included to illustrate the design.
