— This paper proposes energy efficient of automatic street lighting system based on low cost microcontroller. The main objective is to design energy efficient based controller for controlling the Light Emitting Diode (LED) based street lamp via appropriate lighting levels control. This system is consists of a microcontroller, light sensor, rain sensor,(More)
Solar electricity from Grid-Connected Photovoltaic (GCPV) systems has experienced rapid growth as one the most important renewable energy technologies globally. However, due to the intermittent and fluctuating weather conditions throughout the day and year, it is often a challenge to model the output performance of a GCPV system. This paper presents a model(More)
This paper presents a Bat Algorithm (BA) for sizing optimization of Grid-Connected Photovoltaic (GCPV) system. BA was used to search for the optimal photovoltaic (PV) module and inverter from their respective databases such that the expected Specific Yield (SY) in kWh per kWp could be maximized. In addition, the sizing process also involves the dimensioning(More)
— In IC design environment, the chip performance is influence by design environment, schematic and sizing parameter of the transistor. Therefore, this study is an attempt to investigate the performance of 4-bit Brent Kung Parallel Prefix Adder using Silvaco EDA Tools and targeted to 0.18um Silterra Technology. The objective of this project is to review the(More)
