Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas[1] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement in contexts of data broadcasting.
Lambda calculus (also written as λ-calculus) is a formal system in mathematical logic for expressing computation based on function abstraction and application using variable binding and substitution. It is a universal model of computation that can be used to simulate any Turing machine and was first introduced by mathematician Alonzo Church in the 1930s as part of his research of the foundations of mathematics.
Lambda calculus consists of constructing lambda terms and performing reduction operations on them
The LED Display System is used at the colleges and schools for displaying day-to-day information continuously or at regular intervals during the working hours. Being a WIRELESS transceiver system, it offers flexibility to display flash news or announcements faster than the programmable system. The wireless-based display system can also be used at other public places like schools, hospitals, railway stations, gardens etc. without affecting the surrounding environment. The LED display system mainly consists of a WIRELESS transceiver and a display toolkit which can be programmed from an Arduino. It consists of the main purpose is to convey the information through the LED. It can serve as the information passing in as an electronic display board and display the important displays instantaneously this avoiding the latency. Being wireless, the WIRELESS based LED display is easy to expand and allows the user to add more and more display units at any time and at any location in the campus depending on the requirement of the institute.
Waste heat is that which is generated in a process by way of fuel combustion or chemical reaction, and then dumped into the environment even though it could still be reused for some useful and economic purpose.

In simple terms, Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information. And instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. Since simple light bulbs are used, there can technically be any number of access points.
This technology uses a part of the electromagnetic spectrum that is still not greatly utilized- The Visible Spectrum. Light is in fact very much part of our lives for millions and millions of years and does not have any major ill effect. Moreover there is 10,000 times more space available in this spectrum and just counting on the bulbs in use, it also multiplies to 10,000 times more availability as an infrastructure, globally.

Abstract— This paper accurately models photovoltaic (PV) arrays based on genetic and Cuckoo Optimization algorithms. These algorithms are used to obtain the parameters of the array model based on a PV cell datasheet information. In this work, a comparison between the two-diode model and the single-diode model is presented. The adopted model is implemented on simulation platforms using MATLAB 2020a environment and it is designed to be of use to power electronics specialists. The mathematical analysis of the model is presented in detail where different cases of different temperature and solar irradiance are adopted. The model was tested and validated with experimental data. Validation and comparison data are taken from the Mutah university PV power plant. The results show that the two-diode model is more accurate than the single diode model, Cuckoo optimization algorithm handles the problem with low iterations and better fitness value as compared with the genetic algorithm. The work in paper is useful for power electronics designers and researchers who need an effective and more accurate way to model and simulate photovoltaic arrays.

Q.3. Write a Precise for the passage given below: [ 15]
The best definition of an adult that was ever given is one who has stopped growing at both
ends and has begun to grow in the middle. But no one has ever given a good definition of
a teenager.
George Bernard Shaw once said, ' It is a pity that youth has been wasted on the young'.
The contrary is true. It is no secret at all that the Good Lord knew, it was better to put the
illusions of light at the beginning, in order that as we grew closer to eternity, we might
better see the purpose of living.
Since we cannot think of a good definition of a teenager, possibly it would be interesting
to discuss the psychology of the teenager. The psychology of the teenagers may be
reduced to three dominant characteristics: self consciousness, imitativeness and
restlessness.
The difference between a child and a teenager is that a child wants to be loved, a teenager
wants to Jove. The affection of free choice are preferred to the natural affections in 'the
family.
When the teenager emerges, he discovers his own personality and begins to affirm his
ego. A teenager is like a chick just breaking the shell in which he has been confined - the
shell of the family- and beginning to find himself in a great, broad world.

Identification bracelets begin to appear: 'its me'. Up to this point, his life has been merged very
much in the family. If the parents say, 'We are going to visit Aunt Jane today', the child has to
go. But the teenager puts up an arguments; he refuges to be a part of an anonymous group . His
personality asserts itself, saying, '1 don't want to go.' This is the age when the boy begins to
carry a comb, and the girl wins the battle of lipstick. The only word in which they feel at home is
with fellow teenagers.
Hence they have a language of their own. Only in their own mIlieu do they feel they are
understood.
They are proud of it when nobody understands them. Ordinary words have little exchange value,
particularly with adults. There is much they would have to say if they could find words. Fear of
being misunderstood drives them to silence or else to bebop talk, which only the initiated can
understand. '
In addition to that, they love to wear clothes that attract attention. They feel that there is a kind of
conspiracy against their own ego which they resist by over asserting themselves. The boys wear
socks that are so loud their feet can never go to sleep. Girls do their hair a thousand different
ways to express various personalities. There is a fondness for writing names on fences, driving
hot rods, making loud noises on street corners and in buses, in order that people may be
conscious that here, at last, a personality is beginning to emerge. Gestures are quick, gauche, and
awkward. Sloppiness is cultivated to attract attention; feelings are easily hurt. But all these are
signs that a personality is being born into the adult world, and democracy is founded on
personalities. Be not too hard on them.
The second characteristic of the teenager is imitation. The ego must emerge from its inferiority.
It may do it in one of two ways, either by creation or by imitation. If the teenager is keen on
developing his own character, being himself and not someone else, then he creates; he assumes
responsibility; he has a sense of value, and he discovers the purpose of life and concentrates on
the development of his character in a constructive way. His is willing to say 'No' to certain
things. He resists the crowd and the mob, knowing that the crowd and the mob are often wrong.
There are not many, however, who are creative, even the minority.
The third characteristic of a teenager is restless. The teenager is like mercury which can be
dispersed in several directions. The restlessness is due in part to the discovery of vital and
biological impulses stirring within.
Th~ body - imperative is more immediate than the so~ - imperative. Hence, the teenager finds
perseverance difficult and the long attention to the same subject almost impossible. It is this
fidgety quality which most tries the patience of adults. He discovers less the laws than the
illusion life. This tremendous physical energy is ready to spend itself on a tackling dummy or
jitterbugging but almost completely disappears when mother wants the screens put up in the
spring.: time. Puppy love, crushes and infatuations are common, There are friendships that seem
closer than the friendship of teenager and yet there are hardly any friendship that are quite as .
volatile. Adults must remember, however, that this urge for affection, for love, for friendship, for
society, is good and right. God put it in them and it is not to be crushed, but developed along
right lines. (822words)
