Online train ticket booking system project.pdfKamal Acharya
Rail transport is one of the important modes of transport in India. Now a days we
see that there are railways that are present for the long as well as short distance
travelling which makes the life of the people easier. When compared to other
means of transport, a railway is the cheapest means of transport. The maintenance
of the railway database also plays a major role in the smooth running of this
system. The Online Train Ticket Management System will help in reserving the
tickets of the railways to travel from a particular source to the destination.

An In-Depth Exploration of Natural Language Processing: Evolution, Applicatio...DharmaBanothu
Natural language processing (NLP) has
recently garnered significant interest for the
computational representation and analysis of human
language. Its applications span multiple domains such
as machine translation, email spam detection,
information extraction, summarization, healthcare,
and question answering. This paper first delineates
four phases by examining various levels of NLP and
components of Natural Language Generation,
followed by a review of the history and progression of
NLP. Subsequently, we delve into the current state of
the art by presenting diverse NLP applications,
contemporary trends, and challenges. Finally, we
discuss some available datasets, models, and
evaluation metrics in NLP.
2. E-WASTE
E-Waste or electronic wastes are the discarded electrical and electronic devices
that have reached the end of their life. It contain over 1000 different substances
many of which are toxic and creates environment pollution and hazardous for
human health.
It also contains resources like metals which can be recovered and reused.
Examples of e-waste are computers, cellular phones, stereos, refrigerators, air
conditioners, other consumer durables, etc.
E-waste is not hazardous waste but its constituents are hazardous.
4. DIFFERENT CATEGORIES OF E-WASTE
CLASSIFICATION EXAMPLES
1) Lighting equipment Bulb, CFL
2) Consumer equipment T.V., Radio, Video camera, Amplifiers
3) Medical devices With the exception of all implanted and
infected products, Radio therapy equipment,
dialysis, etc.
4) IT and Telecommunication PCs, Printers, Telephones
5) Monitoring and control Smoke Detectors, Heating Regulators,
instruments Thermostat
5. 6) Toys leisure and sport Computer/Video Games, Electric trains
equipment
7) Electrical and electronic tools Drills, Saws, Sewing machine
8) Large and Small household Refrigerator, Freezer, Washing Machine,
appliances Cooking appliances, Grinders, watches, etc.
9) Automatic dispensers For hot drinks, Money, etc.
6. E-WASTE CHALLENGES
• High Volume of e-Waste,
• Limits or restrictions to dump e-waste with Municipal Solid Waste in Landfills,
• Growing number of Product Types,
• Heavy, Bulky and complex Waste to process,
• Requires special logistics and new handling facilities, with new e-waste processing
Technology.
7. EFFECT OF E-WASTE ON THE ENVIRONMENT
Toxic chemicals from e-waste enter the soil and shows its presence in the food
chain of living organisms.
These are non-biodegradable and cause soil pollution.
E-Waste dumping yards and nearby places are polluted and cause health
hazards.
Due to the toxins released by e-waste to the soil, growth of plants get affected
and also these toxins enter the river and lakes and also affects aquatic life.
8. EFFECTS OF E-WASTE ON HUMAN BODY
ELEMENTS EFFECT ON HUMAN BODY
1) LEAD (found in printed Affects brain development of child, damages
circuit boards) kidney, blood system, central nervous system, etc
2) CHROMIUM DNA damage and Asthmatic Bronchitis.
(chip resistors
and semiconductors)
3) MERCURY Chronic damage to brain and respiratory system,
(Switches and flat
screen monitors)
9. 4) CADMIUM Causes neural damage, accumulates in kidney and
(CRTs, computer ) liver, toxic irreversible effects on human body.
batteries, etc.)
5) Plastics including It causes reproductive and developmental problems,
PVC damages immune system, interfere with regulatory
(Cable insulation/) hormones, etc.

11. • LANDFILLING: (1) It is one of the most widely used methods for disposal of
e-waste in India.
(2) Here, trenches are made on the flat surfaces and soil is
excavated from it.
(3) Then waste materials are buried in it, which is covered by a
thick layer of soil.
• INCINERATION: (1) It is a controlled and complete combustion process, in which
the waste material is burned at a high temperature (900 to 1000
degree celsius).
12. (2) Some plants remove iron from the slag for recycling.
(3) By incineration some environmentally hazardous organic
substances are converted into less hazardous compounds.
• RECYCLING: Recycling is a process of dismantling that is removal of different
parts of e-waste containing dangerous substances like, Hg, separation
of plastic, segregation of ferrous and non-ferrous metals and printed
circuit boards, hard drives, floppy drives, Compact disks, mobiles, fax
machines, CPUs, Memory chips, Connecting wires and cables can be
recycled.
13. ENVIRONMENTAL FRIENDLY METHODS OF E-
WASTE MANAGEMENT
• Approaches for Bioremediation
1) Bioremediation includes all the actions that takes place in order to biotransform an
environment which has already altered by contaminants, to its original state.
2) Microbiological processes can be applied to mobilize metals from electronic waste
materials.
3) Bacteria: Thiobacillus, thiooxidans, T.ferrooxidans, and fungi- Aspergillus niger,
Penicillium simplicissimum will grow in the presence of electronic scrap.
4) The formation of inorganic and organic acids caused the mobilization of metals.
14. 5) Both of the fungi Aspergillus niger, Penicillium simplicissimum were able to mobilize
Cu and Su by 65%.
6) Al, Ni, Pb and Zn by more than 95%.
7) Thiobacillus were able to leach more than 90% of the available Cu, Zn, Ni & Al, Pb
precipitated as PbSO4 while Sn precipitated probably as SnO.
18. • E-waste generated in the US, Eastern Europe, Australia (developed countries) is
exported to the developing countries like India, Afghanistan, Western Europe, China,
Pakistan, Ghana, Benin, Egypt, Nigeria, etc.
• 93% of E-waste, generated in US is exported to Asian Countries like India, China,
Malaysia, Singapore, etc.
• 7% of E-waste, generated in US is exported to Mexico and Canada.
• On average each American generated 29.5 kg of E-waste, compared to less than 5
kg per person in China.
19. • Above graph shows that, with time and as with development, global e-waste
generation will increase which is not good for the environmental health.
