| 1 | Conceptualizations of High-Performance Antennas for Use in Wearables | 1.Mehaboob Mujawar, 2.Dr R Purushotham Naik, 3.Dr M Pavithra Jyothi |
A type of antennas that can be worn on the body for lengthy periods of time without losing performance is what this study aims to create. The following qualities should be present in the suggested antennas: (1) being ergonomic and conformal to prevent any discomfort; (2) minimizing radiation into the human body for safety reasons while also ensuring a high on-body radiation efficiency; and (3) utilizing reasonable materials and manufacturing processes to reduce the overall cost and maintain a certain level of robustness. These characteristics are listed in descending order of importance. The belt buckle was chosen as the foundation for the suggested antenna designs because it had all of these desirable characteristics. The belt buckle's metal has a rigid structure that allows the designs to be both effective and strong. Two unique inventive types of belt antennas will be covered in this thesis. The second one is based on a design resembling a single tongue buckle, while the first one is based on a design resembling a pin buckle. An internal reverberation chamber is being built in order to precisely measure the on-body radiation effectiveness of the suggested antennas. Textile electromagnetic bandgap materials are being investigated and used with the second belt antenna in order to improve the on-body radiation efficacy of the antenna from its present level of roughly 40% to a level of over 70%. |

| 3 | Electrical Vehicle Powered By BLDC Motor | 1.Jogu Akhila, 2.Ch.Ramaiah |
The best alternative for e mobility is electric-based transportation. The importance for electrical transportation increasing rapidly throughout the world due to the decrease in conventional fuels like petrol and diesel. In India, still, most of the transportation is using the conventional I.C. engine vehicles only. According to the surveys, it may take five to ten more years to replace all the existing vehicles with electric vehicles. An electric vehicle or drive train requires several subsystems such as the battery, charging circuit, motor drive, converters, and other controlling circuits. Out of all the subsystems, the vital system in a vehicle is the electrical motor used in the electrical vehicle design. Several motors are available such as a three-phase induction motor, synchronous motor, reluctance motor, and brushless D.C. motor. Out of all the motors, the more suitable motor for electric vehicle applications is the BLDC motor, which provides high torque under starting and running conditions. Hence, the vehicle will be effective by employing the BLDC motor. In this project, the model of the BLDC based electric vehicle is created, and the output waveforms are presented. The model of the vehicle is created in MATLAB/SIMULINK. The vehicle is operated under various conditions. The output waveforms of various subsystems are obtained. |

| 4 | Design Of DC-DC Converters For On-board Charging Applications | 1.R.Saritha, 2.T.Jayanth |
Climate change and the greenhouse effect are the major motivational factors for the development of electric transportation systems word wide. The major components in electric vehicles are the motor, energy storage system, and control circuits. Out of all the major research areas in current trend are the charging technologies. Various charging techniques available are static charging, dynamic charging, etc. Using the charging circuits of an electric vehicle, the power can be transferred from grid to vehicle and also from vehicle to grid. The power flow will be from the grid to the vehicle if the battery storage is less. But, it is possible to send back the power from vehicle to grid if the bidirectional charging circuit is employed in the vehicle. This requirement can be utilized during the lack of power produced by renewable energy sources. In this paper, a bi-directional charging circuit for electric vehicles is designed and simulated. The charging circuit can send and receive the power in both directions. The simulation results of the charging circuit are shown and the waveforms related to the charging and discharging are also shown. Entire simulations are performed in SIMULINK. |

| 5 | An Experimental Study On Partial Replacement Of Cement With Flyash And Alccofine In Concrete | 1.Shaik Dilshad, 2.P Siva Kumar |
With the growing technology in concrete world and urbanisation there is lot of requirements of raw material. Due to scarcity of non-renewable resources, concrete making materials are required to be preserved, so there is utmost necessity of using supplementary waste materials in concrete. The waste materials like fly ash, silica fume, lime stone quarry fine, blast furnace slag etc can be used as replacement of cement to address the issue of environmental pollution. In present study an attempt has been made to investigate the strength and shrinkage characteristics of concrete by partially replacing cement by fly ash in different proportions. To supplement the loss in strength of concrete due to addition of fly ash at higher percentage levels, another cementations material alccofine as partial replacement of fly ash had seen used to prepare binary and ternary mixes respectively. The results obtained in present study showed that there is marked improvement in compressive strength and shrinkage properties of concrete with addition of fly ash and alccofine both.
