This study investigated potential ammonia impacts on a sand dune nature reserve 600 m upwind of an intensive poultry unit. Ammonia concentrations and total nitrogen deposition were measured over a calendar year. A series of ammonia and nitrogen exposure experiments using dune grassland species were conducted in controlled manipulations and in the field.(More)
The real time Battery Monitoring System (BMS) has been designed using LabVIEW Interface for Arduino (LIFA). The voltage devide was used for sensing of battery voltage and the ACS712 based on effect hall sensor was used for current sensing. The computer with Ni LaBVIEW calculated and observed voltage and current of Battery. The result showed that BMS can(More)
In transportation, BLDC motors are required to have high torque. This BLDC electric motor is designed to drive an electric car. Increased torque can be done in many ways one of which is the selection of the stator material. Effect on the generated torque can be studied by replacing its stator materials. Design was begun with determining the electrical(More)
A Wireless Battery Monitoring System (WBMS) for electric vehicle has been developed for monitoring voltage, current and temperature of battery. This system consists of hardwares (sensors, a microcontroller, a bluetooth module, an Android smartphone) and software. It was designed on a low cost microcontroller ATMEGA 328 (Arduino UNO). Voltage, current and(More)
This paper presents dynamic voltage collapse prediction on an actual power system using support vector regression. Dynamic voltage collapse prediction is first determined based on the PTSI calculated from information in dynamic simulation output. Simulations were carried out on a practical 87 bus test system by considering load increase as the contingency.(More)
Brushless direct current (BLDC) motor is now widely used for industrial and automotive field since its efficiency is higher than a permanent motors and it has relatively small size. Therefore modelling of BLDC was necessary for its application. The objective of this research was to investigate the performance of BLDC motor modeled by using ANN. The target(More)
A research on the preparation of graphite waste powder from zinc-carbon primary battery has been conducted in order to use the powder as anode material for LiFePO<sub>4</sub> (LFP) battery. The result shows that the component of graphite powder is dominated with carbon and some impurities. The LFP battery with graphite waste powder shows charging capacity(More)
Illuminance level in the softcopy image viewing room is a very important factor to optimize productivity in radiological diagnosis. In today's radiological environment, the illuminance measurements are normally done during the quality control procedure and performed annually. Although the room is equipped with dimmer switches, radiologists are not able to(More)
This research study the application of graphite waste from primary battery and its composite with TiO<sub>2</sub> and Cu-TiO<sub>2</sub> as anode for Li-ion battery. The graphite waste in rod form were sliced into 1 mm thickness of thin pellets, then the titania layer were coated by chemical bath deposition. In order to modifiy the TiO<sub>2</sub>/Graphite(More)
