ExoskeletonBhaskar JhaThis document outlines an exoskeleton, which is a wearable device that enhances its user's strength and mobility. It discusses the types of exoskeletons, their main components like a skeleton, microcomputers, power supply and wrist band. It also describes how exoskeletons like the Ekso suit can help paralyzed patients walk again by powering joints and allowing users to stand, walk and climb stairs. While exoskeletons provide benefits, they also face challenges related to power supply, weight and cost.
History of NavigationgautamanuragThe document summarizes the history of navigation from ancient times to modern day. It describes how early navigators stayed close to shore and used landmarks to navigate before later developing tools like charts, quadrants, and astrolabes to determine latitude and longitude. Key advances included the invention of the chronometer to measure longitude in 1764 and modern technologies like radar, Loran, and GPS satellites that provide highly accurate global positioning. The overall progression showed how explorers improved navigation techniques and tools over time to trade, explore new lands, and spread religion more safely and efficiently around the world.
Powered exoskeletonVostrikov ArkadyThis document discusses exoskeletons, including what they are, types of powered exoskeletons such as HAL, HULC, and ReWalk, details about the HULC exoskeleton, and the future of exoskeletons with more efficient energy sources and use replacing wheelchairs.
Ship Management PresentationM HPiracy is increasing, especially off the coast of Somalia, where ships are being targeted. In 2009, there were over 200 attacks and 30 hijackings. Most attacks occur when ships are low and slow, making them vulnerable targets. The pirates' goal is ransom, with over $200 million paid in ransoms in 2009 alone. Navies like the European Union Naval Force are working to counter piracy by patrolling the waters and intercepting pirate ships, but the future remains uncertain as weather conditions can impact pirate activity.
Ship survey presentationGamal MahranThe document discusses the various types of surveys conducted by Nippon Kaiji Kyokai (ClassNK), a ship classification society, including annual surveys, intermediate surveys, special surveys, and docking surveys. The purpose of the different surveys is to inspect the hull, machinery, equipment and overall condition of ships to confirm they meet classification standards and safety requirements. The document provides details on the scope and requirements of each type of survey.
Transport waterSheilalinThe document discusses various aspects of water transport. It describes how water transport carries people and goods via boats, ships, and ferries. Ships can carry heavier loads than trucks or trains. The document outlines different types of water vessels like ocean liners, cargo ships, ferries, and examples of specialized ships like bulk carriers, tankers, and container ships. It also discusses river transport and the use of ships, ferries, and canoes. The advantages of water transport are its ability to carry large loads at low cost, while disadvantages include slow speed and risk of damage from weather.
Satellites presentationVikas SharmaSatellites orbit Earth for a variety of purposes such as communication, weather monitoring, and navigation. They come in different types depending on their distance from Earth, including low-Earth orbit, medium-Earth orbit, and geostationary orbit. The Global Positioning System is a constellation of 24 satellites that provides location and time information to GPS receivers anywhere on Earth.
