In the maritime mechanical world, supercavitation is the most heady method of acclaim. Supercavitation is an effect created when a bubbling layer forms around an object inside a liquid (try imagining the submerged part of the vessel being surrounded by bubbles). The gas layer reduces friction 900 times than normal, which means the vehicle travels much faster than moving in the water.
So any ship equipped with this technology is a great asset to every navy. In addition to its fast and low fuel consumption, its speed and shape make it easy to locate sound waves. It even torpedoed the smoke in the race. Juliet Marine Systems, a private company in Portsmouth, New Hampshire, is trying to make one. It's called MAIL, designed for defense - the protection of naval vessels, and the chase of pirates looking at commercial ships. It can also be an effective ferry in the landing of enemy troops.

A Bicycle

A bicycle is a two wheeled light vehicle is one of the most common as well as important vehicles in our country. It is made with a triangular frame of steel tubes mounted on two wheels. The site is adjusted on the frame. The rear wheels are provided with the pedals. When the pedals are worked with the feet of the rider, the wheel which is connected with the pedals by a chain works and moves ahead and it causes the front wheel to run and thus the cycle runs ahead. A handle bar which is used for keeping balance is attached with the front wheel. There is a brake set and a bell is also attached with the handle bar. A bicycle is very much important means of transport as it is not costly to buy and we have so many cancha and narrow road all over the country in which other vehicle's movement is not easy at all.

Based on the importance, transportation is termed as the most important fact and we cannot do without it for a single day. Amid different types of transportation mode, I prefer the bicycle.

A bicycle is a very common and popular transportation mode and is available around the world. It is mostly used for its light and easy carrying system and for its health benefits as well. The wheels are attached to a frame for smooth movement. It was introduced in the beginning of the 19th century and due to its easy operation, it became famous globally. Interestingly, the number of bicycles produced after its invention has surpassed the number of automobiles. Bicycles are the key transport modes in the backwards geographical locations. It also helps the riders to keep fit as they are to drive it using its foot pedals.

Traffic congestion is a frequent event in my locality in India and most of the time I get late for my office. I have bought a bicycle mostly to go to my office and use it not only for reaching office I use it to go other places as well. I can reach my office in due time and also could reach the other necessary places without getting late for the appointments. Besides, I can have access to a bicycle where even a motorbike cannot enter. So, the riding on a bicycle is beneficial for me. If I use public transports, I have to stand in a queue to get on the vehicle. Moreover, the traffic congestion occurs more during the office hours. So, I ride my bicycle to reach the destinations, particularly at the office before it is late.

Riding a bicycle has numerous benefits. Firstly, it makes you fit on each of your ride every day. The bicycle requires physical labour to ride on. You are to pedal the cycle using your legs to move on and that pedalling requires lot of physical energy. It helps to burn the fat, strengthens your leg muscles, ankles and feet and thus makes you fit physically for your daily activities. Moreover, you could reach your destinations quickly and could also move in places where motorbikes cannot enter easily. Riding a bicycle is much better than running in the morning or evening. So, I started using the bicycle in my everyday transportation.
  A bicycle is my preferred mode of transportation for different reasons. Firstly, it is economic to ride on a bicycle as the price of fuels and gas is on the rise. So, if you are on your bike, you are saving your bucks. Secondly, riding helps to feel you relaxed physically. As you are riding, you are having physical exercise and that will remove all your stresses away. Besides, it helps to lose the unwanted weights from your body and regular riding will change your shape and also will improve your stamina. Safety is another issue which is rarely found in the other transportation mode. When you are riding, you will pedal after your needs and there is no need to start racing with the other vehicles, thus there are comparatively fewer chances of accidents.

Robotics is a technique that includes design, fabrication, operation, and application robots, just like computers for controlling, reflecting their signaling and processing information. These technologies involve automated machines used to replace people in hazardous fields or in derived products, or catches of symbols, behaviors, and / or cognitions. Many robots today are inspired by animals, also called biological guessing robots.

The idea of ​​making machines can be automatic from the ages, but functional and applied studies did not make much progress until the 20th century. Throughout history, Recognition is to imitate human actions, and often manage tasks in a similar manner. Today, robots are a rapidly evolving field. Through technology development links, robots have been created to serve many different purposes, including underwater robots, industrial robots, or military robots. . Many robots have replaced toxic jobs such as detonating bom

Although much of today's robots are either human-driven or operate in a static environment, attention to robots can operate autonomously in an increasingly dynamic environment. These robots require some combination of hardware and navigation software to move the environment. Special events (such as people and other obstacles that are not fixed) can cause problems or collisions. Some advanced robots such as ASIMO and Meinü Robot have particularly good hardware and navigation software. There are also auto cars, Ernst Dickmanns unmanned cars, and other vehicles in the DARPA Grand Challenge, which are able to sense the environment well and then make a navigation based decision. This information. Most robots use a GPS device to orientate with coordinates, along with radar, sometimes combined with data from other sensors such as LIDAR, camera, and navigation system. Better direction between coordinates.

If robots work effectively in families and other non-industrial environments, the way they are programmed to do work, and especially how they are ordered to stop work will be very important. . Those who interact with them may have little to no training in robots, and communication interfaces will therefore need to be very intuitive. Sci-fi writers often assume that the robot will eventually be able to communicate with humans through speech, gestures, and facial expressions, rather than a command line interface. Although speech is the most natural way for people to communicate with each other, it is not natural for the robot. It takes a long time before the robot can interact as naturally as the fictional C-3PO robot

The era of technology will bring enormous profits to companies, by reducing labor costs and increasing productivity through automated machinery. Experts call this the second economy, as technology almost completely replaces humans and transactions only take place on computers. It will produce a new billionaire class who benefit from the development of technology, both the seller and the buyer.

Meanwhile, a large number of workers will lose their jobs and will not be able to support themselves and their families. While their qualifications do not afford to find another job. That will be a very difficult problem for the whole economy.

"Contrary to fears that automation technology and robots will leave millions of workers jobless all over the world, job opportunities will not go away, but it needs development. While jobs that robots have been able to replace and do not require humans, there are still jobs that involve higher technology. "

Therefore, according to experts, the main solution is the training of higher qualified workers. In the future we will be able to face two possibilities. Firstly, if the labor force is well reformed and can handle highly technical jobs, the world will grow tremendously with the support of machinery technology and, own.

However, the second scenario is somewhat worse, as the speed of renovation does not keep pace with the growth of science and technology. Then there will be so many unemployed people, leading to social chaos, the decay of the rich and the poor, the economic burden that will put the world in crisis.

leuhahahihastudy well!
