Marine Navigation Systems

Ship navigation system that is already set in the Global Maritime Distress adan Safety System (GMDSS). The GMDSS is an international agreement in which regulate communication procedures, the procedure’s safety, as well as the types of equipment in the ship. The purpose of the agreement is to improve safety and also to make procedures easier to implement in order to avoid danger. Existing communication systems in the GMDSS indeed have been specially designed to ensure the safety and necessity of handling signaling distress in the sea and this applies to the whole world. Of course, this system has other capabilities that send and receive signals sent by the danger of another ship, the ship that affected so they can immediately get help as soon as possible. This system can also be used to study the safe route that will pass quickly and safely.

Some systems are incorporated in the GMDSS has long operated with functions as diverse as general radio communication which aims to ship communication tools through a network of terrestrial radio and safety related. Ship navigation systems such as alerting useful to give notice of a disaster or threatening danger as well as to coordinate an inter-ship aid. Tool – navigation tools that are typically used in marine vessels such as radar (radio detection and ranging), GPS (global positioning system), RDF (radio direction finder), enchosounder, AIS (automatic identification system), and many others. The navigation tool must meet the standards set by the GMDSS as to ensure the safety of the crew is in the ships.

GMDSS communication system is divided into two satellite communication systems and ground communications systems created with the aim to coordinate the danger signals between ships on the high seas. Communication is done can be within a range of short, medium, or remotely by using a specific frequency that VHF (very high), and MF (medium), and HF (high) frequency. The main function of the navigation system in the ocean is to determine the bow that can be known within a ship from origin to destination. An explanation of the navigation system briefly ships can illustrate the complexity of existing systems on ships. To that end, a driving ships and crews should be aware of the GMDSS and navigation systems used by ships dikemudikannya with the aim to prevent any unwanted bad thing. For that, it needs a deeper introduction of navigation tools such ships to know the basic things about the navigation tools that are used all ships.

An Artificial Muscles Super Wide to Heal If Trimmed

An Artificial Muscles Super Wide to Heal If Trimmed

With the nano meter technology, it is not impossible to make a very stretchy material. Materials have been found with the use of certain types of rubber and carbon coating with nano meter scale. Super elastic material when it is made with the intended use of super elastic sensor. But when the super elastic material that is truncated, it is definitely the tool can not be reused. The invention allows for the production of super elastic and can heal themselves when cut. The researchers found the idea of human muscle to be stretched and can heal themselves after suffering an injury. When you pull a muscle a little force, perhaps you will feel extreme pain for a while. But the human body can heal any damage incurred as a result of this forced stretching muscles.

Now researchers makes it possible to replicate using electrically-responsive polymer. These polymers are used to make artificial muscle for robotic haptic systems and experimental. So when there are robots that use of these polymers in the cable and the other part, is expected when punctured or cut, the robot can heal themselves and can return to work as it should.

This is the first time the use of electrically responsive polymer with super elastic properties and can be self-healing, so it can be used as artificial muscles more resilient. Thanks to the super-elastic properties of the polymer used, a sheet of electrically responsive polymer with a length of 2.5 centimeters can be stretched up to 2.5 meters long. It’s fantastic not result ?! The researchers then tried to stab the polymer. When the polymer was stabbed, miraculously the polymer may recover. Even the electrically responsive polymer is able to heal themselves well in room temperature conditions. Continue reading
