The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

Japan, unmanned aircraft builded..[ 1858 ]

Researchers build unmanned aircraft to scan Japan's most forbidding locales

Researchers from the University of Tokyo and Mitsubishi Electric Corp. have developed an unmanned aircraft to provide detailed aerial images of wetlands, mountains and other natural areas that are difficult for humans to reach.
The new unmanned aircraft will help researchers observe slight changes in nature with the camera attached to its body, which can take up to 400 color images during a single flight, capturing objects on the ground as small as 2 square centimeters in size. The research team plans to use their invention to monitor ecosystems across the country.
The aircraft -- about 1.7 meters wide and weighing around 2 kilograms -- can be folded and carried in the trunk of an automobile. Flight routes can be programmed into the global positioning system (GPS) of the craft, which flies at an altitude of 80 to 150 meters for up to 30 minutes on a single charge.
To date, researchers have often been forced to give up on aerial photography from helicopters and airplanes due to bad weather. Moreover, they have been unable to obtain detailed photographs because they had to avoid flying at low altitudes for safety reasons.
During the test flight last month, the unmanned aircraft successfully took photographs of small pale pink polygonum flowers in the Yawata wetlands in Hiroshima Prefecture, where a number of aquatic plants have been lost over the past few years. The area has been turned into grasslands after the prefectural government started a water channel development project in the wetlands in fiscal 2007.
"The daily operating cost of unmanned aircraft is 1 million yen, about 10 percent of the expense of flying conventional airplanes. We can see the effectiveness of the project, and it will be helpful (for the government) to improve policy efficiency by adjusting measures if needed," said developer and University of Tokyo professor Shinji Suzuki.
