Green and Light Weight Vehicles Power Transmission System Design and Development

The learning on green vehicle was introduced and promoted to reduce the difficulty of air toxic waste caused by emissions of conventional vehicle. The Green mobility are vehicles with low fuel energy consumption and low zero exhaust gas emission, these vehicles are like hybrid, battery powered, and fuel cell electric vehicle that can be enhanced to be more efficient than the conventional vehicles through a new design and development of power transmission system. Power transmission system for green and lightweight vehicles consists of different components like gear box, propeller shaft, differential and final drive. 

In this review more emphasis is given to gear box due to some reasons firstly, it is one of the heaviest component of the power train system and as a result weight reduction is critically needed to increase the efficiency of the vehicle. Secondly, gearshift takes place therefore, torque interruption needs to minimize. The outcome from the simulation software will be validated by investigational tests on test rigs. 

One way of minimizing fuel consumption is to reduce the weight of the gearbox by 10 reduction in vehicle mass can enhanced fuel economy by about to 7 . The dissimilar researchers confirm that to have high vehicle efficiency the type of the transmission they used matters. A vehicle using automated manual transmission AMT and dual clutch transmission is more efficient in terms of less energy loss and gearshift comfort.

Analysis of Active Power Flow Control with Phase Shifting Transformer in AC Transmission Line

Nowadays, active power flow should be controlled because voltage fluctuation occurred on various load conditions. Phase shifting transformer PST is used to control the active power flow in three phase electricity transmission network. It can increase reliability and can serve as an alternative to new investments in overhead lines. The control of active power flow is achieved by adjusting the phase angle of the voltages at the PST terminals. In this paper, 230 kV AC transmission line is chosen for active power flow control. 

Two conditions, maximum and minimum load conditions are considered as a case study for active power flow control performance in a selected line. Simulation of active power flow with PST model is carried out by using Matlab software. Finally, according to simulation results, system voltages and active power depend phase angles are revealed in this paper.

Design and Simulation of 80 kHz High Frequency Converter Using CD 4047IC CMOS

The electrical power appliances which convert source frequency to another frequency level is known as frequency converter. This research proposed a novel design method to achieve the 80 kHz high frequency converter. In this design, the circuits have been made which contains step-down transformer, inverter circuit using MOSFETs, CD 4047IC and step-up transformer. Single phase source is used as a source. 

Therefore, the rectification is used to convert the AC source to DC source and to supply the 12V by using voltage regulator. Inverter is used to convert DC to AC. Circuit simulation was done by using Proteus software.

Optimization of Process Parameters in MIG Welding of Two Dissimilar Materials

The joining of dissimilar Aluminum Alloy and Copper aluminum plates of 5mm thickness was carried out by technique. Optimum process parameters were obtained for joints using statistical approach. Five different tool designs have been employed to an alyse the influence of rotation speed and traverse speed over the micro structural and tensile properties. In FSW technique, the process of welding of the base material, well below its melting temperature, has opened up new trends in producing efficient dissimilar joints. Effect of welding speed on microstructures, hardness distribution and tensile properties of the welded joints were investigated. 

By varying the process parameters, defect free and high efficiency welded joints were produced. The ratio between tool shoulder diameter and pin diameter is the most dominant factor. From micro structural analysis it is evident that the material placed on the advancing side dominates the nugget region. The hardness in the HAZ of 6061 was found to be minimum, where the welded joints failed during the tensile studies.

Analysis and Comparision of Different Spectrum Sensing Technique for IEEE 802 11

The electromagnetic spectrum is natural resources. The use of wireless communication grows day by day but spectrum allocation policies is static, it tends to increase the spectrum scarcity problem. COGNITIVE RADIO refers to advance wireless radio which aims to improve the spectrum utilization by identify unused spectrum from environment. Spectrum sensing proposed the key method of cognitive radio which detects the presence of primary user in licensed frequency band to utilize unused spectrum. There are three categories of spectrum sensing techniques Non-Cooperative System, Cooperative System, Interference Based Sensing. 

The current work aim on the performance analysis of Non-Cooperative System under low and high SNR, validating the result and applied the technique for IEEE 802.11 WLAN , IEEE 802.16 WIMAX . To estimate the threshold chi-square equation has been solve and identify no. of detected signal, signal under AWGN with the help of MATLAB software. It has been observed during analysis that energy rises at high SNR under AWGN and under high SNR no. of detected signal decreases gradually when the no. of sample increases. Under low SNR no of detected signal increases when no. of sample increases gradually.

Experimental Analysis of Optical Coherent Communication System in India Through Atmospheric Turbulence

Free Space Optical FSO communication is the transmission of optical signals through the atmosphere. This technology promises high wireless data rates, highly secured transmission, license-free operation and immunity to electro- magnetic interference. However, FSO reliability is decreased considerably by atmospheric conditions. In this paper, we characterize the Ghanaian atmospheric channel for FSO communication based on visibility statistic. We use Kruse's model to estimate atmospheric attenuation in India. The probability of outage on an FSO link is computed to determine the availability of the link. Our results show atmospheric attenuation as high as 150.95dB km and 128.2316dB km in the 850nm and 1550nm transmission window respectively. The average atmospheric attenuation in India for 850nm and 1550 nm wavelengths is below 2dB km. The Probability of encountering higher attenuation condition is low.

Water Quality Issues Related to Special Industrial Zones Along Hlaing River

In this study water quality of Hlaing River was monitored along the downstream reach during low flow periods and water samples were collected once a week during January and February. Stations for sample collection were fixed after site survey. There are altogether 14 stations to analyse water quality of the study river reach. The monitoring program includes collection of samples from seven locations along the river into which seven streams discharge. 

These samples were analysed for a number of water quality parameters such as temperature, total dissolve solid, total suspended solid, Conductivity, Salinity, pH, BOD, COD and Arsenic. The results of water quality parameters showed significant variation in water quality of the river and the water quality monitoring data were compared to the water quality standards for different uses.It is found that water quality of Hlaing River deteriorates and doesn't meet the requirements for conserving of living environment due to the pollution from the tributary streams which received wastewater from adjacent industrial zones and newly Satellite town.
