SCADA system is more porpular than other control system in the modern industrial processes. This research describes the automated switch control for SCADA based electrical distribution system of primary substation by using PLC. The objective of this research is to transform the manual control system to automated switch control system in Myanmar. There are four main portions in SCADA based electrical distribution system. They are automated control system, interfacing units, monitoring system and networking system. The automated control system is emphasised in this research. This system can be accomplished by using PLC ladder diagram. This automated distribution system is analyzed to develop a secure, reliabe and convenient management tool which can use remote terminal units (RTUs). The simulations based approach automated system are demonstrated in this research. According to the simulation results, the proposed aut...

The present study examines the incidence of these Wormian bones in dry skulls in the North costal Andhra Pradesh. Materials and Methods and Results: In a sample study of 58 skulls, we have found in 14 of them (24.13%), the Wormian bones confined to the lambdoid suture only and their number ranging from 1 to 4. When in multiples they showed a tendency to be more on the right side. We have not found any of them in the coronal suture or sagittal suture or at the pterion. One skull showed quite a large Wormian bone extending into the occipital bone. (Figures)

Materials, methods and results: Ina sample study of 30 cadavers at NRI medical college, Chinnakakani, Andhra Pradesh (24 males and 6 females), we have found variations in the various branches and reported (figures).

Research paper thumbnail of The Maxillary Arch and Cephalometric Measurements: Comparing Ethnic Malays and Ethnic Chinese in Malaysia

Mean ages were 23.5 years (Malay) and 21.1 years (Chinese), and both groups were brachycephalic with the cephalic index 86.4 for Malay and 85.9 for Chinese which is not significantly different between them. Means of anterior arch width (AAW), posterior-arch-width (PAW) and arch-length were significantly different between two groups. AAW and PAW were significantly different from their corresponding indices for Malays but not for Chinese. The Pont's and Korkhaus' Indices could not be applied to the Malays but moderately to the Chinese.

Research paper thumbnail of Diesel Engine Dynamics Modeling Considering Fuel Injection Period Based on Combustion Heat Release Rate Identification

The behaviors of intake and exhaust systems are also important because these systems govern the fluid flow into engine cylinders. This study presents a diesel engine dynamics model based on the identification of the combustion heat release rate and intake and exhaust valve properties. Using the identification results, instantaneous engine speeds and cylinder pressures can be obtained by considering fuel injection period, air intake and exhaust properties, the in-cylinder combustion process, and crank rotational dynamics. The simulation results for the engine speed and in-cylinder pressure indicate good agreement with experimental data for different external loads and low and high engine speeds.
