Development of a Integrated Air Cushioned Vehicle (Hovercraft)IJMER
The design and development of a hovercraft prototype with full hovercraft basic functions is
reported by taking into consideration, size, material and component availability and intermediate
fabrication skill. In-depth research was carried out to determine the components of a hovercraft
system and their basic functions and in particular its principle of operation. Detailed research in design
was done to determine the size of component parts, quite in accordance with relevant standard
requirements as applicable in the air cushioned vehicles (ACV). The fabrication of the designed
hovercraft by using materials that are readily available by taking into consideration the economic
constraints and time constraints. It also includes the testing process which includes the tweaking of
various parameters that govern lift and thrust of the hovercraft. Further research is recommended to
improve on the efficiency of the craft.
The air cushion vehicle or “HOVERCRAFT”, as it is popularly known is the newest vehicle in today’s transport scene. As well as being new, this vehicle is different from other more conventional, terrestrial vehicle in that it requires no surface contact for traction and it is able to move freely over a variety of surface while supported continuously on a self-generated cushion of air. Though the concept is new, the rate of development of hovercraft has been outstandingly faster than that of any other mode of transport.

These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze rapid improvements in the economic feasibility of robotic exoskeletons. These exoskeletons can be worn by workers in harmful environments and physically disabled people. By sensing a person’s nerve impulses, these exoskeletons can activate motors that help people move and lift heavy objects. Improvements in biosensors, ICs, materials, batteries, and other components have enabled dramatic reductions in cost and weight, and improvements in response time
The world today has about 4000 offshore support vessels of various types. While statistical data are not very precise, there appears to be more than 200 under construction at present. These modern vessels, intended for fleet replacement on the one hand, and to meet the more demanding needs of deeper water operations on the other, are of much improved designs and packed with multifunctional capabilities.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2) Flies like a plane.
3) It can hover over or move across land or water surfaces while
being held off from the surfaces by a cushion of air.
4) Float like a boat.
6. 4) A Hovercraft can travel over all types of
surfaces including grass, mud, muskeg, sand,
quicksand, water and ice .Hovercraft prefer
gentle terrain although they are capable of
climbing slopes up to 20%, depending upon
surface characteristics.

10. 1) The first design by Swedish designer Emmanuel Swedenborg in 1716.The
project was short-lived because it was never built.
2) In 1915 Austrian Dagobert Müller built the world's first "water effect"
vehicle.
3) In 1931 Finnish aero engineer Toivo J. Kaario began designing a developed
version of a vessel using an air cushion and built a prototype.
4) During World War II an engineer in the United States of America, Charles
Fletcher, invented a walled air cushion vehicle. Because the project was
classified by the U.S. government, Fletcher could not file a patent.
11. INVENTION
1) The idea of the modern
hovercraft is most often associated
with Sir Christopher Cockerell.
2) Cockerell built several models of
his hovercraft design in the early
1950s.
15. Basic Structure Of
Hovercraft
Parts Of Hovercraft
o Propeller :-
It pushes the hovercraft
ahead by pushing air behind.
o Fan :-
Primary purpose is to inflate
the cushion contained
within the skirt beneath the
craft as well as to provide
thrust with which to propel
the craft forward.
o Skirt :-
Part that allows the
hovercraft to clear
obstacles. Generally
speaking, the higher the
skirt, the larger the obstacle
that the craft will clear.
16. Detailed Construction Of
Hovercraft
Construction of hovercraft varies
according to it’s Applications.
17. Radar: apparatus that detects objects through the use of
microwaves.
Pylon: supporting post.
Dynamic propeller: two-bladed apparatus that provides
motion.
Fin: steering device.
Rudder: apparatus that prevents drift.
Lift-fan air intake: opening to allow air to enter.
Main level drive gear box: compartment that contains and
protects the gear mechanism.
Skirt finger: part of the flexible skirt.
Passenger entrance: opening on the side wall that provides
access to the passenger cabin.
Flexible skirt: lower flexible part.
Bow door ramp: opening at the front.
Control deck: cubicle from which a hovercraft is operated.
18. Principle Of Working
#) To lift the craft by a cushion of air to propel it
using propellers.
#) The air sucked in through a port by large lifting
fans which are fitted to the primary structure of the
craft.
#) They are powered by gas turbine or diesel
engine.
19. #) Fan is used to inflate the skirt and rest is
ducted down under the craft to fill area
enclosed by the skirt.
#) At the point when the pressure equals
the weight of the craft, the craft lifts up and
air is escaped around the edges of the skirt.
#) So a constant feed of air is needed to lift
the craft and compensate for the losses.
20.
21. 1) Travel over any surface.
2) Shortcutting routes.
3) Travel rivers up as fast as down, irrespective of the current.
4) Travel in dry water-beds
5) No collision with debris, logs etc.
6) Access to 75% of coastal area instead of only 5% with conventional vessels
22. #) Hovercraft are very fuel efficient
(CO² friendly) as Hovercraft do not
have to plough through the water
but "fly" above the surface. At
maximum speed fuel consumption
of a Hovercraft is approx. 70% less
than of a fast patrol boat with
similar payload capacity.
#) No turbulence or impact in water
as no propeller churns up the water
so sea life remains untouched.
23. 1) They move a lot of air and can be relatively
loud.
2) Steep grades can be issue.
3) Potential of skirt damage/puncture.
4) Not exactly agile (eg: cornering).
24. Applications of Hovercraft
• Border/coastal/inland patrol, anti terrorism, drug
smuggling patrol.
• High speed marine sub surface & ground scanning survey
& detection.
• Rescue work from flooded areas, mud, sand, tidal areas.
Rescuers can reach floods, mud, sand & ice victims
without exposing rescuers to life threatening danger.
• Distribution of famine or flood aid support craft. Relief

rocks, coral, or marine life.
• Filming & TV work. Store sales & advertising (Harrods).
26. The future of hovercraft
seems uncertain, but there is
a good chance there will be
huge hover ports all over the
world, like the one in the
picture. Thinner hovercraft
might be built so civilians
can drive safely on roads..
27. • Hovercrafts have been a must have for coast guard
veterans, disaster relief agencies, and personnel,.
Publicly and commercially, rescue services to those in
need.
• personal fishing excursions,
• accommodate previously hard to reach locations,
providing transportation, goods and delivery services
more effectively than before, while law enforcement,
military, and government patrol and rescue outfits can
find their mark quickly and effortlessly, no matter the
terrain’s composition.
• With unique ingenuity comes exceptional design, style
and reliability. Hovercrafts are safe, exciting to use
and drive, and are easier to own than ever!
