Abstract

Horizontal Axis Wind Turbine (HAWT) had been widely used in Malaysia, however, research concluded that the power produced is still low which approximately 0.02% from the wind turbine input is. The average wind speed in Penang, Malaysia, is recorded between 1.0 m/s to 2.5 m/s whereby to produce 2.7 kW of power by HAWT, 12.0 m/s of average wind speed is needed. Therefore, the main objective in this project is to develop and analyse the suitability on the Vertical Axis Wind Turbine (VAWT) to be used for power generation with the wind speed in between 0.5 m/s to 3.0 m/s. Ducting system is chosen rather than the open air since commercial buildings used Heat Ventilation Air Conditioning (HVAC) system. Arduino microcontroller and LabVIEW is used as interfaced to setup two types of sensors that is temperature sensor and anemometer.

Abstract

Cyclic voltammetry electrochemical biosensors reported a wide usage and applications for its fast response, able to be miniaturized and its sensitivity. However, the bulky, expensive and laboratory-based readout circuitry made it impossible to be used in the field-based environment. A miniaturized and portable readout circuitry for the DNA detection using hybridization technique had been design and developed in this work. It embedded with fabricated FR4 based sensor and produced respective current when the applied voltage was within the range of 0 to 0.5 V. The readout circuitry had been verified with five analysis environments. Bare Au with distilled water (dH2O), bare Au with ferricyanide reagent solution, DNA immobilization, DNA non-hybridization and DNA hybridization. All the results performed produced peak cathodic current when the applied input voltage is within 0.5 V to 3 V and hence proved that the miniaturized and portable readout circuitry is suitable to be implemented for cyclic voltammetry electrochemical biosensor.

Abstract

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.
