Radar Coastal Surveillance - Essay Example The primary aim of the present research is the determination of the extent to which radar systems efficiently and effectively execute the requirements and tasks associated with coastal surveillance. Hew (2006), a defence systems analyst with the Defence Science and Technology Organisation, contends that no single radar system is capable of fulfilling the stated tasks and responsibilities but that coastal area characteristics have to be matched against specific systems. In other words, the selection of the coastal radar selection system is dependant upon the characteristics of the coastal area in question and no radar system addresses the needs and features of all. Proceeding from an acknowledgement of this argument, this study will review all of radar technology, coastal surveillance requirements and existent methods for radar coastal surveillance to determine the optimal system, or systems for the execution of coastal surveillance responsibilities.As a strategy for responding to the selected researched question and satisfying the research's articulated aim, an in-depth investigative exploration of radar technology, coastal radar systems, and the requirements of coastal radar surveillance shall be undertaken. The results of the investigation shall determine the optimal coastal radar surveillance system(s).Prior to presenting the data upon which the discussion pertaining to the research question shall be based, it is necessary to contextualize the report's focus. This shall be done through a review of the definition for radar systems, an historical analysis of its development and the articulation of its responsibilities and tasks. 2.1 Background Practically all systems, from computer and communication systems to air and naval defense systems may ultimately be identified as multi-tasking technological networks, comprised of several asynchronous parallel distributed operations and whose total response is, by definition, both complex and probabilistic. Further evidencing the inherently complex nature of systems is the fact that operational responses vary in accordance to output events

Art history from 1580-1980 - Essay Example This was 1793 painting of nude man with an appearance a real classical young man. Other paintings before 1800 that show naturalism are Francisco Goya’s paintings named â€Å"And so Was His Grandfather† and â€Å"You who cannot†. Artists highly engaged with the nature from 1580-1980. They did this by spending their time to study nature. They started shifting from religious and supernatural paintings to nature paintings. They engaged with nature in their art by portraying objects in their arts as they appear exactly in reality. This was done based on the artists’ scientific knowledge. There was a strong connection between science and art. Examples of paintings that depict nature include John constable’s â€Å"The Hay Wain† and Joseph Mallord’s â€Å"Snowstorm: Hannibal and Army† (Rothko & Rothko 65). Other nature paintings include Theodore Gericault’s â€Å"The Raft of Medusa† and William Blake’s â€Å"Dante Running from The Three Beasts†. All these were painted after 1800. Nature was depicted in the renaissance arts in various forms. For instance, it was presented in paintings, sculptures and music during that period. Naturalism was significant to many artists and movements. For instance, it was significant to humanisms movement. During the renaissance period the society had started to focus more on human values than religious values. As such, artists painted humans in the natural world to show their position on earth. Nature was also significant to naturalism movement where artists were recognized based on how well their represented nature in their paintings. Nature became a source idea for many artists. They got their ideas by simply studying or observing it (Rothko & Rothko
