Hydrographic survey is the survey of physical features present underwater.
This slide briefs you about the definition of the survey, its application, use, etc. It also discusses the sounding process used in the hydrographic survey.
UNMANNED SURFACE VEHICLE (USV) FOR COASTAL SURVEILLANCEIAEME Publication
The purpose of this paper is to design and fabricate an unmanned surface vehicle (USV) for the coastal surveillance for the maritime of India. It aims to monitor territorial waters on a round-the-clock basis and allows the intelligence to take appropriate action to prevent terrorism, illegal smuggling and human trafficking as the continuous use of an aircraft for surveillance is prohibitively expensive along the Indian coastline which is a massive stretch measuring 7,517km.In this paper an Air Cushioned Vehicle (ACV) popularly known as a Hovercraft is chosen for surveillance as it has the ability to traverse any surface compared to other coastguard vessels thereby earning the title of amphibious boats. Its ability to access 75% of littoral allows them to come on shore during emergencies unlike conventional coastguards that have only 5% littoral access and cannot enter shallow water.

Transforming Brand Perception and Boosting Profitabilityaaryangarg12
In today's digital era, the dynamics of brand perception, consumer behavior, and profitability have been profoundly reshaped by the synergy of branding, social media, and website design. This research paper investigates the transformative power of these elements in influencing how individuals perceive brands and products and how this transformation can be harnessed to drive sales and profitability for businesses.
Through an exploration of brand psychology and consumer behavior, this study sheds light on the intricate ways in which effective branding strategies, strategic social media engagement, and user-centric website design contribute to altering consumers' perceptions. We delve into the principles that underlie successful brand transformations, examining how visual identity, messaging, and storytelling can captivate and resonate with target audiences.
Methodologically, this research employs a comprehensive approach, combining qualitative and quantitative analyses. Real-world case studies illustrate the impact of branding, social media campaigns, and website redesigns on consumer perception, sales figures, and profitability. We assess the various metrics, including brand awareness, customer engagement, conversion rates, and revenue growth, to measure the effectiveness of these strategies.
The results underscore the pivotal role of cohesive branding, social media influence, and website usability in shaping positive brand perceptions, influencing consumer decisions, and ultimately bolstering sales and profitability. This paper provides actionable insights and strategic recommendations for businesses seeking to leverage branding, social media, and website design as potent tools to enhance their market position and financial success.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

2. INTRODUCTION
Under water vehicle are of 3 type:
• Remoted operated
vehicle(RUVs)
• Unmanned underwater
vehicle(UUVs)
• Autonomous Underwater
Vehicle(AUVs)
3. AUVs
An autonomous underwater vehicle (AUV) is a
robot which travels underwater without
requiring input from an operator.
The first AUV was developed at the Applied
Physics Laboratory at the University of
Washington as early as 1957 by Stan Murphy,
Bob Francois
4. Design of the AUVs……
• The vehicle is 21" (53 cm) in diameter, and about 8 ft.
(2.5 m) long.
• It weighs about 450 lbs. (200 kg).
• It is capable of operating at water depths up to 4500
m with a nominal velocity of 3 kts (1.5 m/s). In a
survey mode it has a maximum range of about 50 km
i.e. (31.0686).
5. Parameters of the AUVs are as follows:-
1. SENSORS
2. NAVIGATORS
3. PROPULSION
4. POWER
6. SENSORS
• Primarily oceanographic tools, AUVs carry
sensors to navigate autonomously and map
features of the ocean. Typical sensors include:
I. compasses
II. depth sensors
III. side-scan sonars
IV. magnetometers
V. thermistors
7. Navigation
• AUVs can navigate using an underwater acoustic positioning system. When
operating within a net of sea floor deployed baseline transponders this is known
as LBL navigation. When a surface reference such as a support ship is
available, ultra-short baseline (USBL) or short-baseline (SBL) positioning is
used to calculate where the subsea vehicle is relative to the known (GPS)
position of the surface craft by means of acoustic range and bearing
measurements.
• Inertial navigation is a dead reckoning type of navigation system that computes
its position based on motion sensors. Once the initial latitude and longitude is
established, the system receives impulses from motion detectors that measure
the acceleration along three or more axes enabling it to continually and
accurately calculate the current latitude and longitude. Its advantages over other
navigation systems are that, once the starting position is set, it does not require
outside information, it is not affected by adverse weather conditions and it
cannot be detected or jammed.
8. PROPULSION
• AUVs can rely on a number of propulsion techniques, but propeller based
thrusters or Kort nozzles are the most common by far. These thrusters are
usually powered by electric motors and sometimes rely on a lip seal in
order to protect the motor internals from corrosion.
9. POWER
• Most AUVs in use today are powered by rechargeable batteries (lithium
ion, lithium polymer, nickel metal hydride etc.), and are implemented with
some form of Battery Management System. Some vehicles use primary
batteries which provide perhaps twice the endurance—at a substantial extra
cost per mission. A few of the larger vehicles are powered by aluminum
based semi-fuel cells, but these require substantial maintenance, require
expensive refills and produce waste product that must be handled safely. An
emerging trend is to combine different battery and power systems with
Ultra-capacitors.
10. Applications Of AUVs
Commercial Uses
The oil and gas industry uses AUVs to make detailed maps of the seafloor
before they start building subsea infrastructure; pipelines and sub sea
completions can be installed in the most cost effective manner with
minimum disruption to the environment. The AUV allows survey
companies to conduct precise surveys of areas where traditional
bathymetric surveys would be less effective or too costly.
Military Uses
A typical military mission for an AUV is to map an area to determine if
there are any mines, or to monitor a protected area for new unidentified
objects. AUVs are also employed in anti-submarine warfare, to aid in the
detection of manned submarines.
11. Research Uses
Scientists use AUVs to study lakes, the ocean, and the ocean floor. A
variety of sensors can be affixed to AUVs to measure the concentration of
various elements or compounds, the absorption or reflection of light, and
the presence of microscopic life. Additionally, AUVs can be configured as
tow-vehicles to deliver customized sensor packages to specific locations.
