Have you pulled your car up to the gas/petrol pump lately and been shocked by the high
price of gasoline? As the pump clicked past Rs1400 or 1500, maybe you thought about
trading in that SUV for something that gets better mileage. Or maybe you are worried
that your car is contributing to the greenhouse effect. Or maybe you just want to have
the coolest car on the block. Currently, there is a solution for all this problems, it's the
hybrid electric vehicle.
The vehicle is lighter and roomier than a purely electric vehicle, because there is less
need to carry as many heavy batteries. The internal combustion engine in hybrid-electric
is much smaller and lighter and more efficient than the engine in a conventional vehicle.
In fact, most automobile manufacturers have announced plans to manufacture their own
hybrid versions. Hybrid electric vehicles are all around us. Most of the locomotives we
see pulling trains are diesel-electric hybrids. Cities like Seattle have diesel-electric
buses -- these can draw electric power from overhead wires or run on diesel when they
are away from the wires. Giant mining trucks are often diesel-electric hybrids.
Submarines are also hybrid vehicles -- some are nuclear-electric and some are dieselelectric. Any vehicle that combines two or more sources of power that can directly or
indirectly provide propulsion power is a hybrid.
Its a free source of energy we know very well man has needed and used energy at an increasing rate for the sustenance and well-being since time immemorial. Due to this a lot of energy resources have been exhausted and wasted. Proposal for the utilization of waste energy of foot power with human locomotion is very much relevant and important for highly populated countries like India where the railway station, temples etc., are overcrowded all round the clock .When the flooring is engineered with piezo electric technology, the electrical energy produced by the pressure is captured by floor sensors and converted to an electrical charge by piezo transducers, then stored and used as a power source. And this power source has many applications as in agriculture, home application and street lighting and as energy source for sensors in remote locations.

Nowadays pollution is a major issue for whole world. Pollution is manmade and can be seen in own homes. In case Gas powered lawn mowers due to the emission of gases it is responsible for pollution. Also the cost of fuel is increasing hence it is not efficient. So the Solar powered lawn cutters are introduced. Solar powered lawn mower can be described as the application of solar energy to power an electric motor which in turn rotates a blade which does the mowing of a lawn. Solar energy is the renewable energy. Grass cutter or lawn mowing with a standard motor powered lawn mower is an inconvenience, and no one takes pleasure in it. Cutting grass cannot be easily accomplished by elderly, younger, or disabled people. Motor powered push lawn mowers and riding lawn mowers create noise pollution due to the loud engine, and local air pollution due to the combustion in the engine. Also, a motor powered engine requires periodic maintenance such as changing the engine oil. Even though electric lawn mowers are environmentally friendly, they too can be an inconvenience. Along with motor powered lawn mowers, electric lawn mowers are also hazardous and cannot be easily used by all.
Detailed presentation on the basics of an electric vehicle, comparison of different motors for EV application, comparison of different batteries for EV application, Charging infrastructure for EV in India and a brief on BMS(Battery Management System).
Vehicles to travel from one place to another are among the greatest gifts of science to mankind. Of course, man has not stopped at mere wheeled contraptions to travel upon from one place to another. They developed the modern cars that are nothing short of great wonders, so much so that they have their own movies made. One of the most famous movies about cars is Fast and Furious. The seventh movie of the series has been released on 26 March, 2015, and features some of the best cars the series has shown so far. Let us take a look at The Cars In Fast And Furious 7.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

9. INTRODUCTION
Amelioration of standard of Living and industrialization leap up the pressure on the conventional
sources of power. Depletion of conventional sources becomes a problem in present world. And
ever rising cost of conventional fuel may be major impediment in economic and social growth of
third world nations.
All of us (developing and developed nations) are searching for new and newer sources of energy
and its efficient use. Moving towards modernization, luxuries become necessities which lead the
people towards the need of personal vehicle thus contributing to the substantially increased
traffic density. This increased traffic density can be utilized for generation of Electricity by using
an innovative Technique.
In this project work an attempt has been made to fabricate a ramp, by which we can utilize the
energy in power generation. This may further be used in battery charging.
The efficiency of our machine is some where 0.4 to 0.5 percent. It is seems a very small number
but if we think in terms of number of vehicles and time it will be a huge amount of energy saved.
This type of ramp is best suited for the places where the speed breaker is a necessity. The places
like Toll bridges and vehicle parking stands are best for its utilization.

13. 2.3 CHAIN AND SPROCKET MECHANISM
Chains are made up of number of rigid links which are hinged together by pin
Joints in order to provide the necessary flexibility for warping round driving and
driven wheels. These wheels have projecting teeth of special profile and fir into
the corresponding recesses in the links of chain as shown in figure. The toothed
Wheels are known as sprocket wheels or simply sprocket.
The chains are mostly used for transmit motion and power from one shaft to another,
when the centre distance between their shafts is short such as in bicycle, motorcycle,
agriculture machinery, etc
In the case of bicycle chains by varying the size (and therefore, the tooth count) of the
sprockets on each side of the chain, we can modify the overall gear ratio of the chain
drive. By providing different-sized driving sprockets and different-sized driven sprockets.

14. 2.4 FREEWHEEL
In mechanical or automotive engineering, a freewheel is a device in a transmission
that disengages the driveshaft from the driven shaft when the driven shaft rotates
Faster than the driveshaft. This condition exists in a bicycle going downhill when
the rider holds his feet still, no longer pushing the pedals. Without a freewheel,
with a fixed connection between the rear wheel and the pedals, the rear wheel
Would drive the pedals round.The simplest freewheel device consists of two saw-toothed,
spring-loaded discs pressing against each other with the toothed sides together, somewhat
like a Ratchet. Rotating in one direction, the saw teeth of the drive disc lock with the
teeth of the driven disc, making it rotate at the same speed. If the drive disc slows down
or stops rotating, the teeth of the driven disc slip over the drive
Disc teeth and continue rotating.

15. 2.5 PULLEY AND BELT
A pulley is a wheel with a groove along its edge, the pulleys are used to transmit
power from one shaft to another by means of flat belts or ropes. Since the velocity ratio
is inverse ratio of diameter of driving and driven pulleys.
The belts are used to transmit power from one shaft to another by means of pulley
which rotate at the same speed or different speed.

16. 2.6 DYNAMO
It is an electrical generator that produces direct current with the use of a commutator.Dynamos
were the first electrical generators capable of delivering power for industry and the foundation
upon which many other later electric power conversion devices were based ,including the electric
motor,the alternating current alternator,and the rotary converter.Today,the simpler alternator
dominates large power scale power generation,for efficiency,reliability and cost reasons.

17. 2.7 WIND MILL
A wind mill is a machine that converts the energy of wind into rotational energy by means of
vanes called blades or vanes. The reason for the name “WIND MILL” is that the devices
originally were developed for milling grains for food production; the name stuck when in the
course of history windmill machinery was adapted to supply power for many industrial and
agricultural need other than milling. The majority of modern wind mills take the form of wind
turbines used to pump water, either for land drainage or to extract groundwater.

18. 2.8 LIGHT EMITTING DIODE
A light emitting diode (LED) is a two lead semi conductor light source that resembles a back pn
junction diode; expect that an LED also emits light. When an LED’s anode lead has a voltage
that is more positive than its cathode lead by at least the LED’s forward voltage drop, current
flows. Electrons are able to recombine with holes within the device, releasing energy in the form
of photons. This effect is called ELECTROLUMINESCENCE and the colour of light
(corresponding to the energy of the photons) is determined by the energy band gap of the
semiconductor.

20. WORKING PRINCIPLE
LAW OF INERTIA
According to Newton’s law of inertia, force is designated as the product of mass and
acceleration, where acceleration is measured relative to an inertial reference.
Newton’ law F =M*A.
LAW OF DYNAMIC FRICTION
The stage when the body acted upon by an external force is just on the point of moving,
is called limiting equilibrium of the body. The force of friction which is offered by the
rough surface at the stage of limiting equilibrium, is called limiting friction. When a
body starts moving, the force of friction offered by the surface is called the dynamic
friction
.
When a body is at the point of limiting equilibrium the force of friction is maximum. The
angle which the resultant of the maximum force of friction and normal reaction make
with the normal reaction is called the angle of friction. It is denoted by tan lamda
Tan lambda = Maximum force of friction/ Normal reaction.
The ratio of the limiting friction and normal reaction is called coefficient of friction.

21. BELT AND CHAIN
Belt and chain are used for the power transmission from one shaft to another shaft.
According to law of belting, the centre line of the belt as it approaches the pulley must lie
in a plane perpendicular to the axis of that pulley, or must lay in the plane of the pulley,
otherwise the belt will run off the pulley.
Power transmitted by the belt = (T1 – T2)*V/75.
If T be the number of teeth on chain, p the pitch, d the pitch circle diameter, then
D = p cosec (180/T).
Gears are mainly used for transmission of power and motion; gears are used when
positive drives are necessary and when the centre distance is relatively short.
FARADAY LAW OF ELECTRICITY
Electric current flows from positive to negative polarity but electrons flow reverse
direction. Current flows when electrons find a path to move along. Electricity is
measured in ampere.
Coulomb is the basic quantity of electricity. One coulomb equals 6.25 billion electrons.
WORKING
As the vehicle passes over the ramp, there‘s is a surface contact between vehicle tires
and roller, which will tend to rotate the roller, it is free to rotate as it is supported on
bearings which are mounted on T-shape supports which are bolted to wooden base.

23. CALCULATIONS:
Here,
w1 = Angular Speed of Vehicle Tire (rad/sec)
w2 = Angular Speed of Roller (rad/sec)
d1 = Diameter of Tire (mm)
d2 = Diameter of Roller (mm)
v = Velocity of Vehicle (m/sec)
I = Moment of Inertia of Roller (pipe)
Do = Outside Diameter of Roller (mm)
Di = Inside Diameter of Roller (mm)
V = Voltage (volts)
I = Current (Ampere)
T = Time (seconds)
R = Rotational Kinetic Energy of Roller (Joules)
E = Electrical Energy (Joules)
When Velocity ofVehicle is, v=2.78m/sec
d1=600mm
d2=165mm
And v=r*w.
So, w1= 2.78 / (d1/ 2)
= 2.78 / (.600 / 2)
= .00926 rad / sec
And, (w1/w2) = (d2/d1)
So, w2= (.0926*600) / 165
= .0336 radian / sec

24. Moment of Inertia of Roller, I= (3.14*(do4-di4)) / 64
= d0= 165mm
= did = 155mm
=8046250mm4
Rotational Kinetic Energy of Roller= (I*w2*w2) / 2
= (8046250*.0336*.0336) / 2
= 4541 J
Electrical energy= V*I*t.
= 5*.8*4
= 16J
Efficiency=Electrical Energy / Rotational Kinetic Energy
=16 / 4541
=.004
=.4percent
When Velocity ofVehicle is, v=3.32m/sec
d1=600mm
d2=165mm
And v = r*w.
So, w1 = 3.32 / (d1/2)
= 3.32 / (.600/2)
= .01108 radian/sec
And, (w1/w2) = (d2/d1)
So, w2 = (.01108*600)/165
= .0401rad/sec

25. Moment of Inertia of Roller, I= (3.14*(do4-di4)) / 64
= d0=165mm
= did =155mm
=8046250mm4
Rotational Kinetic Energy of Roller= (I*w2*w2)/2
= (8046250*.0401*.0401) / 2
= 6469 J
Electrical Energy = V*I*t
= 5.5*1*4
= 22 J
Efficiency=Electrical Energy / Rotational Kinetic Energy
= 22 / 6469
= .0045
= .45percent
When Velocity ofVehicle is, v=4.155m/sec
d1=600mm
d2=165mm
And v = r*w.
So, w1 = 4.155 / (d1/2)
= 4.155 / (.600/2)
= .0138 radian/sec
And, (w1/w2) = (d2/d1)
So, w2 = (.0138*600)/165
= .0503 radian/sec

26. Moment of Inertia of Roller, I = (3.14*(do4-di4))/64
= do =165 mm
= di =155 mm
= 8046250 mm4
Rotational Kinetic Energy of Roller = (I*w2*w2)/2
= (8046250*.0503*.0503)/2
= 10057J
Electrical Energy = V*I*t.
= 6.8*1.2*4
= 34 J
Efficiency= Electrical Energy / Rotational Kinetic Energy
= 34 / 10057
= .0048
= .48percent

28. CONCLUSION
We concluded that, electricity is generated by our project. By implementing we
Observed that on moving a vehicle over the roller speeds varying from 10-15 km/hr,
And in this region 5-7 volts is being produced. Speed Vs energy plot shows that energy
produced is directly proportional to speed but there will be a limit of Mechanical
Instruments.
The efficiency of air set ups is about 0.4 to 0.5%, which seems a very small value but if we see it
in terms of numbers of vehicles passed per unit time, there will be huge amount
of energy saved.

29. AREA OF UTILITY & FUTURE SCOPE
Electric ramp can be utilized on Express Toll Stoppages for en-lightning the path lights and also
for the ticketing at the pickets. It can be used in rural areas contributing towards high paced
development of villages. As we know most of the villages having electricity problem. So it can
play a major role in en-lightning the streets of villages as well fulfills the basic need of
electricity in villages.
A part from that, energy generated from this should meet the environmental standards and cost-
effective. And finally would like to sum up with the fact that scarcity of electricity in India is
major obstruction towards the development of our country and hitting on the pockets of common
man with increase in the consumption and the prices. So, conservation could be one way to do
that however the other and better way would be to install these electricity generating ramps
where ever possible thus helping our society with catastrophic problem of electricity, rather
government should take an initiative and all the cooperative societies to help and ward off this
problem and making it a success
**THE ELECTRICITY GENERATOR RAMPS**.
If we use concert structure in fabrication of speed breaker on the roads, It will become more
beneficial. The structure of concert works efficiently and reliably. We can also use more rollers
instead of one; also leap up the size of the roller to generate more electricity.
