AAI Aerosonde
The AAI Aerosonde is a small unmanned aerial vehicle (UAV) designed to collect weather data, including temperature, atmospheric pressure, humidity, and wind measurements over oceans and remote areas. The Aerosonde was developed by Insitu, and is now manufactured by Aerosonde Ltd, which is a strategic business of AAI Corporation. The Aerosonde is powered by a modified Enya R120 model aircraft engine, and carries on board a small computer, meteorological instruments, and a GPS receiver for navigation. It is also used by the United States Armed Forces for intelligence, surveillance and reconnaissance (ISR). Design and development On August 21, 1998, a Phase 1 Aerosonde nicknamed "Laima", after the ancient Latvian deity of good fortune, completed a 2,031 mile (3,270 km) flight across the Atlantic Ocean. This was the first crossing of the Atlantic Ocean by a UAV; at the time, it was also the smallest aircraft ever to cross the Atlantic (the smallest aircraft record was subs ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Latvian Mythology
Latvian mythology is the collection of myths that have emerged throughout the history of Latvia, sometimes being elaborated upon by successive generations, and at other times being rejected and replaced by other explanatory narratives. These myths stem from folk traditions of the Latvian people and pre-Christian Baltic mythology. Latvian mythology is used particularly as a tool for reconstructing and analysing the historical pagan beliefs and national identity of Latvia. It is important to note that the minute details of most, if not all of these myths vary per region and sometimes even family. History 13th–18th century There are few reports of Baltic tribes, the ancestors of modern Latvians, and their mythology until Christianization in the 13th century. Since Christianization, there have been several reports related to local mythology including chronicles, travel reports, visitation records, Jesuit reports and other accounts of pagan practices. These reports are considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorological Instrumentation And Equipment
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at Weather prediction, prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

The population of Benbecula were sympathetic to the Jacobite cause, and smuggled him off the island to safety, as the song has it: "over the sea to Skye". In 2006, local residents took control of parts of the island in a community buy-out. The previous landowners, a sporting syndicate, ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border.

Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
