airplane technologies

An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine orpropeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includesrecreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.

The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight".^[1] They built on the works of Sir George Cayley dating from 1799, when he set forth the concept of the modern airplane (and later built and flew models and successful passenger-carrying gliders).^[2] Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal also studied heavier-than-air flight. Following its limited use in World War I, aircraft technology continued to develop. Airplanes had a presence in all the major battles of World War II. The first jet aircraft was the German Heinkel He 178 in 1939. The first jet airliner, the de Havilland Comet, was introduced in 1952. The Boeing 707, the first widely successful commercial jet, was in commercial service for more than 50 years, from 1958 to 2010.

adobe after effects

Adobe After Effects is primarily used as a software for video editors, to create motion graphics and also visual effects. It allows users to animate, edit, and compose media be it 2D or 3D space with many different built-in tools and third party plug-ins which can be downloaded from the Internet depending on what type of plug in the user is looking for. It also provides individual attention to variables like parallax and also user adjustable angles of observation.

Adobe After Effects is a layer-oriented program software. Each individual media object like video clips, still images, audio clips, etc. runs on its own. In contrast, other Non-Linear Editing Systems use a system where individual media objects can occupy the same track as long as they do not overlap at the same time. This track-oriented system is more suitable for editing and can keep project files more simple. The layer oriented system that Adobe After Effects has is suitable for extensive video effects work and also keyframing. Other compositing packages, especially the ones that employ tree or node workflows, such as Nuke Software, and eYeon Fusion, are better suited to managing larger volumes of objects within a composite. Adobe After Effects is capable of countering the problem somewhat by selectively hiding layers or by grouping them into pre-compositions.

The main interface of Adobe After Effects consists of several panels. Three of the most commonly used panels are the Project Panel, Composition Panel, and the Timeline Panel. The project panel acts as a bin to important still images,videos or audio footage items. Footage files in the Project Panel are used in the Timeline Panel, where layer ordering and timing can be adjusted according to the user. The items visible at the current time marker are displayed in the Composition Panel.

Adobe After Effects shares many of the same features with other Adobe programs, such as creating shapes, that are defined by bezier curves. Like Adobe Photoshop and Adobe Illustrator, After Effects can import and manipulate many image formats, filters, and adjustments.

Adobe After Effects integrates with other Adobe Software Programs such as Adobe Illustrator, Adobe Photoshop, Adobe Premiere Pro, Adobe Encore and Adobe Flash. Additionally, it works with third party 3D programs like Cinema 4D, Lightwave 3D, and Autodesk 3D Max.

CPU MADE

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s.^[1] Traditionally, the term "CPU" refers to a processor and its control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.^[2]

The form, design and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations,hardware registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and "executes" them by directing the coordinated operations of the ALU, registers and other components.

Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously calledmicrocontrollers or systems on a chip (SoC). Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called "cores"; in that context, single chips are sometimes referred to as "sockets".^[3] Array processors or vector processors have multiple processors that operate in parallel, with no unit considered central.
