The main aim of this Automatic Illumination of Tunnel project is to saving the power in idle time. For this we have to design an electronic circuit. This is most useful in traffic lights whenever the traffic is more the lights are on with bright, when the traffic is less then automatically lights are in set to off. So the power is automatically save. These tunnels are placed in the underground and this can be used roads like train, busses, vehicles, and canal. The tunnel is relatively narrow and long. The basic tunnels types for construction are cut and cover tunnel, bored tunnels, immersed tube tunnels.

This project uses the concepts of visual adjustment, in this temporal adaption, spatial adaption. For The safety types of the tunnel lighting are symmetrical and asymmetrical lightening, asymmetric counter beam lightening. The arrangements of the tunnel lightening are cell mounting (enough space) and wall mounting (not having enough space) these two techniques are used in this project based on these two concepts the tunnel is arranged. To control the tunnel lighting use the innovative systems, this should be the cost efficient system, optimizing the security, actually the tunnel having not having the control for power consumption, this problem can be solved by using the plc controlled lighting system. By using this project the maintenance cost is reduced, less installation charges. The components used for this project are X-OR gate, OR gate, AND gate, IR transmitter, IR receiver and 555 timer circuit.

This 3G Tutorial seminar topic explain the basic concepts behind the 3G network, it explain about which technology it is using and what type of data rate and the range of the bandwidth. first 1G first generation technology is implemented, this technology uses the concept of frequency division multiple access, that is separate frequencies each and every call so this technology having problems to connect a call, here frequencies are divided, To overcome this problem next 2G second generation technology is come in to existence, this technology uses the concept of time division multiple access, in this technique time slot and TDMA frames are taken into consideration, one time slot is 0.5ms, one TDMA frame is equal to eight time slots based on these the calls are connected in 2G, compared to 1G, 2G is most reliable. Next in 2001 3G network is come in to existence but India not preferred that network at that time due to high cost, in that time some countries used 3G, later in 2010 November 3G services started in India by Tata docomo, due to high data rate, video calling facility, the 3G services are started all networks like Aircel, Airtel, Vodafone, reliance. 3G uses the code division multiple access technique, it uses the frequency reuse concept and hand off concept.

The main aim of this project is to transmit the FM signal using two transistors. In this project we use the two transistors in one circuit. Both transistors are of type BC548. Second transistor base is connected to the collector of the first transistor. The circuit is basically a radio frequency RF oscillator; it operates at 100MHZ frequency range. When the input audio signal is applied to the first transistor then that signal is amplified by the first transistor. Then the output of the first transistor at collector terminal is fed to the base of the second transistor then this signal is modulated and set the resonant frequency. Here to set the resonance frequency we have to change the capacitance value. After setting the resonance frequency then we has to connect to the colpitts oscillator.

This ECE project mainly uses the equipments of transistors, capacitors, resisters, voltmeter to set the voltage value. This project mainly used in transmitting the Frequency modulated signal. There is the limited range for frequency modulated signal. The limit should not be cross. The FM wireless signal should contain licence, without the license it is illegal. Here the difference is used the two transistors for amplification and for modulation.

This Spread Spectrum seminar topic explains about the how the signal is spreading in that area. The spread spectrum is mainly used in military areas because this spectrum is more secure compared the other signals. The spread spectrum cannot interfere with other signal, and this spectrum cannot be modulated. The bandwidth used here is in high range. This spread spectrum is used for multiple access and for multiple functions. Spread spectrum decrease the interference with other signals for secure condition. Normally spread spectrum use the noise for spread in the range of narrow band. The receiver converts the data into original form. This spread spectrum used in phase modulators and this technology explained in 1941. At the starting of founded this technology the army not interested to implement this but after some days they are having the problem with normal signals so they are now implementing the spread spectrum.

There are the techniques to implement the spread spectrum these are direct sequence, multi carrier, frequency hopping, time hopping technique. These are the techniques used for implementation transmission and reception here using the direct sequence spread spectrum for digital data transmission. Spread spectrum clock generation technique is used to avoid the interference. This sends a clock signal, especially for the microprocessors to reduce the spectral density. This ECE seminar topic is mainly used in military areas.

This Hydro Electric Power Electrical Technical Presentation mainly explains about how the hydro electric power is generated by using the water flow. Nowadays electrical power generated sources are from coal, sunlight, water but the main problem is coal level reduced day by day. So to get the power the main resource is hydro electric power. These days all over the world 10 to 16% of the power generated from the water resource. The main aim of this seminar is to get the power from water. To get the hydro electric power we have to construct big dams, reservoirs.

These projects should be constructing with large area and with more height from the mountains the water flows down at that place we have to put the turbine, and then based on the water flow and height of the mountain the power can be generated. When the water is falling from the mountain then the turbines are rotated, when the turbines rotated then power is generated. This falling water should not be waste, this should be sent again to reservoir then the water is not wasted and the more power is generated. So the hydro electric process is good for the power generation, and there is the small and big turbines are available in industry. The small size of turbines generates less power, big turbines generate high power but the problem is that big turbine cost is high even though we have to use big turbines because for high power generation. So this is the best technology to generate power. This Project mainly useful for final year Electrical and Electronics Engineering Students.
