Wind turbine is a device that converts kinetic energy of wind into electrical energy. Weak air pressure with an average of 2m/s to 4m/s makes wind turbine implementation in Malaysia becoming difficult and unrealistic. In order to produce a good power and torque, a quality air pressure is needed. Wind turbine performance depends on the incoming wind speed. Fluctuating and low quality air pressure are the significant challenges in wind turbine implementation. There are many types of mechanism and control but the production of output power is still considered low compared to the actual equipment. In a large building, Heat Ventilation Air Conditioning (HVAC) system is highly required to control the indoor temperature and consistent air pressure through ducting. The consistency of air pressure in ducting system make a drive for this research to proposed a wind turbine implementation in ducting system in order to produce electrical energy. In HVAC there are five parameters to be considered in order to identify the air pressure distribution in ducting system. These five parameters are input air pressure, ducting height, distance between blower to the pipe, total effective length and gap between trunk or run out.  In this paper, an analysis of air pressure  effect in a ducting system will be conducted via a development of air pressure prototype. Thousands of experiments are required with regards to a huge number of experiments to be considered. Spesifically a statistical analysis Taguchi Method is used to reduce a number of experiments. Without statistical analysis, 3125 experiments  shall be conducted to identify the air pressure distribution in the ducting system. However, these huge number of experiments are reduced to only 25 experiment by using Taguchi method based on the function of L25 in array orthogonal

Traditional entrance keys performed a number of drawbacks, including the ease with which they can be stolen, duplicated, or misplaced, allowing unauthorized people to gain access to cash, valuables, and other important documents. As known, most digital electronic entrance locks use application specific integrated circuits (ASICs) as based, which have the disadvantage of being unable to be reconfigured, as opposed to field programmable gate arrays (FPGA). This project proposed a home security code lock using verilog hardware descriptive language (HDL) with two unlocking modes, using a button or a keypad which can be changed using a switch. The 7-segment on the Altera DE2-115 trainer board is used to display the passcode press by the keypad. The result of simulation on the keypad using finite state machine (FSM) technique was fulfill the theoretical concept in which it will go to the next state each time the correct input or passcode was entered. When the wrong input or passcode was entered, it will be entered to reset mode. As the conclusion, a fully comply output according to the theoretical FSM concept is fully achieved in this project.

<span>This work presents a design and development of a remote controller application using an Altera DE2-115 board. A remote controller lighting provides smart technologies make it viable to monitor, control and support users in which can enhance the quality life and promote independent living. Nowadays, to turn on the electrical devices, a user will go to the located switch. It is difficult and required more time to switch on the devices instead of staying at certain location while controlling the switching mode of the devices. Implementing this system, users do not need to have numerous switches in their home to turn on the lights as they can do this digitally from a switchless control located in one place or using a remote controller. The Altera board is built with eighteen slide switches which act as inputs and at the same time it will display the outputs on seven segments, LEDs and LCD display character. As a conclusion, the remote controller lighting system provides convenience and energy efficiency in order to allow the users to control the lighting system using smart devices. </span>
