Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry.

An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

INTRODUCTION
1.1 INDIAN RAILWAY
The history of rail transport in India began in the mid-nineteenth century.Prior to 1850, there
were no railway lines in the country. This changed with the first railway in 1853. Railways
were gradually developed, for a short while by the British East India Company and
subsequently by the Colonial British Government, primarily to transport troops for their
numerous wars, and secondly to transport cotton for export to mills in UK. Transport of
Indian passengers received little interest till 1947 when India got freedom and started to
develop railways in a more judicious manner
Indian Railways is an Indian state-owned enterprise, owned and operated by the Government
of India through the Ministry of Railways.
The first train in the country had run between Roorkee and Piran Kaliyar on December 22,
1851 to temporarily solve the then irrigation problems of farmers, large quantity of clay was
required which was available in Piran Kaliyar area, 10 km away from Roorkee. The necessity
to bring clay compelled the engineers to think of the possibility of running a train between the
two points.[4] In 1845, along with Sir Jamsetjee Jejeebhoy, Hon. Jaganath
Shunkerseth (known as Nana Shankarsheth) formed the Indian Railway Association.
Eventually, the association was incorporated into the Great Indian Peninsula Railway, and
Jeejeebhoy and Shankarsheth became the only two Indians among the ten directors of the GIP
railways. As a director, Shankarsheth participated in the very first commercial train journey
in India between Bombay and Thane on 16 April 1853 in a 14 carriage long train drawn by 3
locomotives named Sultan, Sindh and Sahib. It was around 21 miles in length and took
approximately 45 minutes.
A British engineer, Robert Maitland Brereton, was responsible for the expansion of the
railways from 1857 onwards. The Calcutta-Allahabad-Delhi line was completed by 1864.
The Allahabad-Jabalpur branch line of the East Indian Railway opened in June 1867.
Brereton was responsible for linking this with the Great Indian Peninsula Railway, resulting
in a combined network of 6,400 km (4,000 mi). Hence it became possible to travel directly
from Bombay to Calcutta via Allahabad. This route was officially opened on 7 March 1870
and it was part of the inspiration for French writer Jules Verne's book Around the World in
Eighty Days. At the opening ceremony, the Viceroy Lord Mayo concluded that "it was
thought desirable that, if possible, at the earliest possible moment, the whole country should
be covered with a network of lines in a uniform system"
Indian Railways is the world's seventh largest commercial or utility employer, by number of
employees, with over 1.307 million employees as of last published figures in 2013. As
for rolling stock, IR holds over 239,281 Freight Wagons, 62,924 Passenger Coaches and
9,013 Locomotives. The trains have a 5 digit numbering system and runs 12,617 passenger
trains and 7421 freight trains daily. As of 31 March 2013, 20,884 km (12,977 mi) (31.9%) of
the total 65,436 km (40,660 mi) route length was electrified.[7] Since 1960, almost all
electrified sections on IR use 25000 Volt AC traction through overhead catenary delivery.
7. 1.2 N E RAILWAY GORAKHPUR

2.2 HEAT TREATMENT SHOP
Heat treatment is the process of heating and cooling of a material to change its physical and
mechanical properties without changing the original shape and size. Heat treatment of steel is
often associated with increasing its strength, but can also be used to improve machinability,
formability, restoring ductility, etc. Basic heat treatment process for steels are described in
the following subsections.
DIFFERENT TYPES OF HEAT TREATMENT PROCESS
1. Hardening.
2. Tempering.
3. Austempring.
4. Martempring.
5. Annealing.
6. Spheroidizing.
7. Normalizing.
8. Nitriding.
13. Fig 2.7 heat treatment
Fig 2.8 Iron Carbon Diagram
14. HARDENING
Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite
is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at
which austentizing rapidly takes place depends upon the carbon content in the steel used. The
heating time should be increased ensuring that the core will also be fully transformed into
austenite. The microstructure of a hardened steel part is ferrite, martensite, or cementite.
TEMPERING
Tempering involves heating steel that has been quenched and hardened for an adequate
period of time so that the metal can be equilibrated. The hardness and strength obtained
depend upon the temperature at which tempering is carried out. Higher temperatures will
result into high ductility, but low strength and hardness. Low tempering temperatures will
produce low ductility, but high strength and hardness. In practice, appropriate tempering
temperatures are selected that will produce the desired level of hardness and strength. This
operation is performed on all carbon steels that have been hardened, in order to reduce their
brittleness, so that they can be used effectively in desired applications.
Austempering
Austempering is heat treatment that is applied to ferrous metals, most notably steel and
ductile iron. In steel it produces a bainite microstructure whereas in cast irons it produces a
structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite.
Martempering
Martempering is a heat treatment for steel involving austenitisation followed by step
quenching, at a rate fast enough to avoid the formation of ferrite, pearlite or bainite to a
temperature slightly above the martensite start (Ms) point.
Annealing
Annealing is a heat process whereby a metal is heated to a specific temperature /colour and
then allowed to cool slowly. This softens the metal which means it can be cut and shaped
more easily. Mild steel, is heated to a red heat and allowed to cool slowly.
Spheroidizing
Spheroidizing is a form of heat treatment for iron-based alloys, commonly carbon steels, in
order to convert them into ductile and machinable alloys.
A spheroidized structure in high-carbon steel is usually obtained by a divorced eutectoid
transformation (DET) reaction, which occurs during slow cooling of aus- tenite with fine
cementite particles.
Normalizing
Normalizing Heat Treatment Definition. Normalizing Heat Treatment process is heating a
steel above the critical temperature, holding for a period of time long enough for
transformation to occur, and air cooling.
15. Nitriding
Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create
a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy
steels. However, they are also used on medium and high-carbon
steels, titanium, aluminum and molybdenum. Recently, nitriding was used to generate unique
duplexmicrostructure (Martensite-Austenite, Austenite-ferrite), known to be associated with
strongly enhanced mechanical properties.
2.3 WELDING SHOP
Welding is a fabrication or sculptural process that joins materials,
usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature
metal-joining techniques such as brazing and soldering, which do not melt the base metal. In
addition to melting the base metal, a filler material is often added to the joint to form a pool
of molten material (the weld pool) that cools to form a joint that can be as strong as the base
material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld.
Some of the best known welding methods include:
1. Shielded metal arc welding (SMAW) - also known as "stick welding", uses
an electrode that has flux, the protectant for the puddle, around it. The electrode
holder holds the electrode as it slowly melts away. Slag protects the weld puddle from
atmospheric contamination.
2. Gas tungsten arc welding (GTAW) - also known as TIG (tungsten, inert gas), uses a
non-consumable tungsten electrode to produce the weld. The weld area is protected
from atmospheric contamination by an inert shielding gas such as Argon or Helium.
3. Gas metal arc welding (GMAW) - commonly termed MIG (metal, inert gas), uses a
wire feeding gun that feeds wire at an adjustable speed and flows an argon-based
shielding gas or a mix of argon and carbon dioxide (CO2) over the weld puddle to
protect it from atmospheric contamination.
4. Flux-cored arc welding (FCAW) - almost identical to MIG welding except it uses a
special tubular wire filled with flux; it can be used with or without shielding gas,
depending on the filler.
5. Submerged arc welding (SAW) - uses an automatically fed consumable electrode
and a blanket of granular fusible flux. The molten weld and the arc zone are protected
from atmospheric contamination by being "submerged" under the flux blanket.
6. Electroslag welding (ESW) - a highly productive, single pass welding process for
thicker materials between 1 inch (25 mm) and 12 inches (300 mm) in a vertical or
close to vertical position.
Many different energy sources can be used for welding, including a gas flame, an electric arc,
a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding
may be performed in many different environments, including in open air, under water, and
in outer space. Welding is a hazardous undertaking and precautions are required to
16. avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and
exposure to intense ultraviolet radiation.
Until the end of the 19th century, the only welding process was forge welding,
which blacksmiths had used for centuries to join iron and steel by heating and
hammering. Arc welding and oxyfuel welding were among the first processes to develop late
in the century, and electric resistance welding followed soon after. Welding technology
advanced quickly during the early 20th century as World War I and World War II drove the
demand for reliable and inexpensive joining methods. Following the wars, several modern
welding techniques were developed, including manual methods like SMAW, now one of the
most popular welding methods, as well as semi-automatic and automatic processes such as
GMAW, SAW, FCAW and ESW. Developments continued with the invention of laser beam
welding, electron beam welding, magnetic pulse welding (MPW), and friction stir welding in
the latter half of the century. Today, the science continues to advance. Robot welding is
commonplace in industrial settings, and researchers continue to develop new welding
methods and gain greater understanding of weld quality.
Fig 2.9 welding by torch
Oxy Fuel Welding
Oxy-fuel is one of the oldest welding processes, besides forge welding. Still used in industry,
in recent decades it has been less widely utilized in industrial applications as other
specifically devised technologies have been adopted. It is still widely used for welding pipes
and tubes, as well as repair work. It is also frequently well-suited, and favored, for fabricating
some types of metal-based artwork. As well, oxy-fuel has an advantage over electric welding
and cutting processes in situations where accessing electricity (e.g., via an extension cord or
portable generator) would present difficulties; it is more self-contained, and, hence, often
more portable.
17. In oxy-fuel welding, a welding torch is used to weld metals. Welding metal results when two
pieces are heated to a temperature that produces a shared pool of molten metal. The molten
pool is generally supplied with additional metal called filler. Filler material depends upon the
metals to be welded.
In oxy-fuel cutting, a torch is used to heat metal to its kindling temperature. A stream of
oxygen is then trained on the metal, burning it into a metal oxide that flows out of
the kerf as slag.

MATERIAL HANDLING SYSTEM
Material Handling is the field concerned with solving the pragmatic problems involving
the movement, storage in a manufacturing plant or warehouse, control and protection of
materials, goods and products throughout the processes of cleaning, preparation,
manufacturing, distribution, consumption and disposal of all related materials, goods and
their packaging .The focus of studies of Material Handling course work is on the
methods, mechanical equipment, systems and related controls used to achieve these
functions. The material handling industry manufactures and distributes the equipment and
services required to implement material handling systems, from obtaining, locally
processing and shipping raw materials to utilization of industrial feed stocks in industrial
manufacturing processes. Material handling systems range from simple pallet rack and
shelving projects, to complex conveyor belt and Automated Storage and Retrieval
Systems (AS/RS); from mining and drilling equipment to custom built barley malt drying
rooms in breweries. Material handling can also consist of sorting and picking, as well
as automatic guided vehicles.
MATERIAL HANDLING EQUIPMENT-
Material-handling equipment is equipment that relate to the movement, storage, control
and protection of materials, goods and products throughout the process of manufacturing,
distribution, consumption and disposal. Material handling equipment is the mechanical
equipment involved in the complete system. Material handling equipment is generally
separated into four main categories: storage and handling equipment, engineered systems,
industrial trucks, and bulk material handling.

25. Descriptionof some important parts of air-braking system-
BRAKE CYLINDER- There are two 355 mm brake cylinder under frame, which is fed
by common distributor valve. It has the piston-rod arrangement, which works under
pressure. Brake cylinder is connected to distributor valve on one side and by pivot to the
block cylinder.
BRAKE PIPE- This is charged from the locomotive at 5 kg/cm3 and causes
application and release of brakes due to change in its pressure through the locomotive
control system. The pipe linked to distributor system.
FEED PIPE- It having 6kg/cm3 pressure, and keeps the auxiliary reservoir charge at
fuel pressure even when brakes are applied. Feed pipe are also connected to the
distributor valve.
DISTRIBUTOR VALVE- It is connected to the brake pipe auxiliary reservoir and
brake cylinder. It controls the pressure in the brake cylinder. It controls the pressure in the
brake cylinder in proportion to the reduction of pressure in brake-pipe.
ANGLE COCK- It is use for alarming purpose.
HOUSE COUPLING- Both the brake-pipe and feed pipe are fitted to the angle cock
outlet for the passage of compressed air from one coach to another mean of braided
rubber and metal coupling.
GUARD VAN VALVE & PRESSURE GAUGE- These are provided in the guards
compartments. These are provided to control the train movement.
ISOLATING COCK- Use for isolating the air from one point to the other point.
CHOKE- It is device for restricting the flow of air from one point brakes circuit to other
point. The handle of this cock is kept parallel to the pipe to indicate that it is in open
conditions.
